Abstract
2
This study explored how mothers' observed and self-reported child feeding practices
3
(child control over food choices, encouragement of balance and variety, and teaching about
4
nutrition) were associated with mother-child snack food selections and child snack food
5
consumption in a laboratory setting. Mothers (N = 107) and their 4.5-year-old children (52%
6
female) selected up to 5 snack foods (out of 9 snack foods: 6 higher-energy-density [ED] and 3
7
lower-ED) for optional child consumption throughout a one-hour laboratory visit. Mothers’ in-
8
the-moment child feeding practices during the snack food selection task were coded using
9
observational coding schemes, and mothers’ global child feeding practices (i.e., across meals and
10
snacking occasions) were self-reported using the Comprehensive Feeding Practices
11
Questionnaire (Musher-Eizenman & Holub, 2007). Results of multiple linear regression analyses
12
with covariates showed that higher-ED snack food selections were positively associated with
13
observed child control over food choices (B = 0.35, SE = 0.12, p = .006) and self-reported
14
teaching about nutrition (B = 0.49, SE = 0.19, p = .010), and negatively associated with self-
15
reported encouragement of balance and variety (B = -0.66, SE = 0.24, p = .007). Lower-ED
16
snack food selections were positively associated with self-reported encouragement of balance
17
and variety (B = 0.53, SE = 0.20, p = .008). Child consumption of higher-ED or lower-ED snack
18
foods were not significantly associated with mothers’ child feeding practices (observed or self-
19
reported). We discuss the implications of these findings for future research on children’s snack
20
food selection and consumption.

1. Introduction
24
Accumulating evidence suggests that snacking behaviors are associated with total dietary
25
energy intake (Deming et al., 2017; Shriver et al., 2018), overall dietary quality (Kachurak et al.,
26
2019), and obesity risk (Kachurak et al., 2018) among preschool-aged children (aged 2 to 5
27
years) in the United States. Therefore, it is important to identify factors that are associated with
28
preschoolers’ snacking behaviors, including their selection and consumption of snack foods.
29
Snacking is broadly defined as consuming foods or beverages between meals, and items
30
consumed between these occasions are labeled, “snack foods” (Blaine et al., 2017; Hess et al.,
31
2016). Although snack foods are sometimes defined by their nutritional value (e.g., low-nutrient,
32
high-energy-density foods/beverages; Hess et al., 2016), our definition includes all
33
foods/beverages in order to identify factors associated with variations in the energy density of
34
preschoolers’ snack food selections and consumption.
35
Over the past four decades, the average number of snacking occasions among
36
preschoolers’ in the United States has increased from one to three snacking occasions per day
37
(Dunford & Popkin, 2018). Preschoolers currently consume over 25% of their average daily
38
calories during snacking occasions (Shriver et al., 2018), primarily from high-energy-density
39
foods, such as cookies, potato chips and sugar-sweetened beverages (Deming et al., 2017;
40
Shriver et al., 2018; Welker et al., 2018). Developmental research suggests that preschoolers
41
naturally prefer foods that are high in fat and sugar, which tend to be higher in energy density,
42
and dislike foods with strong bitter flavors, which tend to be lower in energy density, such as
43
green vegetables (Anzman-Frasca et al., 2018; Birch, 1999). Problematically, consuming high-
44
energy-density snack foods has been linked to lower overall dietary quality among preschoolers
45
(Kachurak et al., 2019). Higher overall dietary energy density (i.e. across meals and snacking
4 46
occasions) has in turn been associated with greater obesity risk among children aged 2 to 8 years
47
(Vernarelli et al., 2011), which highlights the importance of research to identify factors
48
associated with the energy density of preschoolers’ snack food selections and consumption
49
(Rolls & Leahy, 2010). Such research stands to inform strategies to improve preschoolers’
50
dietary quality and reduce their obesity risk, and is critical in light of evidence demonstrating
51
poor dietary quality (Hamner & Moore, 2020) and recent increases in the prevalence of severe
52
obesity (Skinner et al., 2018) among preschoolers in the United States.
53
Mothers and other primary caregivers influence the development of preschoolers’ eating
54
behavior through their child feeding practices (Savage et al., 2007; Scaglioni et al., 2018;
55
Vaughn et al., 2016). In the context of snacking, child feeding practices (also known as food
56
parenting practices) include parenting behaviors such as determining the level of child control
57
over snack food choices, encouraging balance and variety in children’s snack food choices, and
58
teaching children about nutritional proprieties of different snack foods (Davison et al., 2015;
59
Gevers et al., 2014). Numerous studies have investigated mothers’ child feeding practices during
60
meals, while relatively fewer have examined mothers’ child feeding practices during snacking
61
occasions (see Blaine et al., 2017 for a review). This is an important gap in the literature because
62
associations between child feeding practices and children’s eating behavior may differ in the
63
context of snacking occasions compared to meals. Indeed, results of two qualitative studies
64
suggest that mothers perceive snacking occasions as distinct from meals, and that parents vary
65
both what and how they feed their children depending on the context (Fisher et al., 2015; Loth,
66
Nogueira de Brito, et al., 2018). For example, parents reported giving preschoolers more control
67
over what and when they ate during snacking occasions compared to during meals (Loth,
68
Nogueira de Brito, et al., 2018). These findings highlight the need for additional research on
5 69 70
associations between mothers’ child feeding practices and preschoolers’ snacking behavior. Although there are numerous child feeding practices that warrant further investigation
71
(see Davison et al., 2015 and Vaughn et al., 2016) child control over food choices,
72
encouragement of balance and variety, and teaching about nutrition are especially relevant to
73
studies of preschoolers’ snacking behavior; these child feeding practices can be observed during
74
snack food selections and have corresponding self-report measures of global child feeding
75
practices. Assessing child feeding practices using both observational and self-report measures
76
can allow for more nuanced insights into associations between mothers’ child feeding practices
77
and preschoolers’ snacking behavior (Fries et al., 2019; Pesch & Lumeng, 2017). For example,
78
observational measures during snacking occasions can capture “in-the-moment” child feeding
79
practices, while global self-report measures can capture parents’ perceptions of their child
80
feeding practices across meals and snacking occasions. Importantly, associations between
81
mothers’ child feeding practices and children’s eating behavior may differ by measurement
82
approach due to the strengths and limitations that are unique to observational and self-report
83
measures (Pesch & Lumeng, 2017). A number of studies conducted during meals have shown
84
inconsistencies between observational and self-report measures of child feeding practices (e.g.,
85
Bergmeier et al., 2015; Farrow et al., 2011; Fries et al., 2019). The extent to which observational
86
and self-report measures of mothers’ child feeding practices differentially predict preschoolers’
87
snacking behavior is currently unknown, which limits the development of nutrition education
88
programming that aims to improve preschoolers’ dietary quality and reduce obesity risk through
89
modifying mothers’ child feeding practices during snacking occasions.
90
A few studies have examined why parents offer snacks to children (e.g., Blaine et
91
al., 2015; Damen et al., 2019, 2020), while much remains to be explored regarding how parents
6 92
affect preschoolers’ snacking behavior through their child feeding practices. A few studies have
93
linked variations in parents’ self-reported child feeding practices to the energy density of
94
children’s snack food preferences and consumption. Regarding high-energy-density (ED) snack
95
foods, children’s liking (Boots et al., 2019) and consumption (Boots et al., 2018; Corsini et al.,
96
2018; Fisher & Birch, 1999) of high-ED snack foods have been linked to higher self-reported
97
global coercive parental control over preschoolers’ eating behavior (e.g., restriction). However,
98
similar associations with self-reported global restriction have not been found in some other
99
studies (e.g., Bauer et al., 2017; Harris, Mallan, Nambiar, & Daniels, 2014). On the other end of
100
the spectrum, parental self-reports of granting children higher control over their own eating
101
behavior have been positively associated with preschoolers’ selection (Wellard et al., 2014) and
102
consumption (Chaidez et al., 2014) of high-ED foods, although these associations were not
103
specific to snacking occasions. Lastly, parents of 4- to 12-year-olds who reported lower child
104
consumption of high-ED snack foods also highly endorsed globally encouraging healthy food
105
and teaching children about food (Gevers et al., 2015).
106
Few studies have examined how parents’ child feeding practices are associated with
107
children’s selection and consumption of low-ED foods, both generally and specific to snacking
108
(see Yee et al., 2017 for a review). There are two notable exceptions: In one study, parents of 3-
109
to 7-year-olds reported lower child liking of fruits when they also reported higher global child
110
control over food choices (Vollmer & Baietto, 2017). Another study found that parents of 2- to
111
5-year-olds reported higher child fruit and vegetable consumption when they reported higher
112
global encouragement of balance and variety and teaching about nutrition (Shim et al., 2016).
113
Additional research is needed to clarify associations between mothers’ child feeding practices
114
and preschoolers’ selection and consumption of snack foods that vary in energy density.
7 115
In the current study, we pursued two related aims on associations between mothers’ child
116
feeding practices and preschoolers’ snacking behavior. This study adds uniquely to the literature
117
through our use of both observational and self-report measures of mothers’ child feeding
118
practices (specifically, child control over food choices, encouragement of balance and variety,
119
and teaching about nutrition). First, we explored the correspondence between mothers' observed
120
feeding practices in the context of a mother-child snack food selection task, and mothers’ self-
121
report of global child feeding practices (i.e., across meals and snacking occasions). Next, we
122
explored how mothers’ child feeding practices (observed and self-reported) were associated with
123
mother-child selections, and child consumption, of higher-energy-density and lower-energy-
124
density snack foods in a laboratory setting. Given the mixed and/or limited findings on these
125
associations in the literature, all analyses were exploratory.
126 127 128
2. Method 2.1 Participants Mother-child dyads were recruited through birth announcements and a local community
129
hospital in central Pennsylvania to participate in a longitudinal study that began when children
130
were 4 to 6 months of age. Mothers were told that the longitudinal study focused on children’s
131
basic needs (e.g., eating, crying, sleeping, soothing) and children’s emotional and physical
132
development. The inclusion criteria for participation in the longitudinal study were: Maternal age
133
≥ 18 years, full-term pregnancy (≥ 37 weeks) without complications (e.g., low birth weight), and
134
plans to remain in the geographic area for at least two years. As part of their on-going
135
participation in the longitudinal study, a subset of the sample participated in a follow-up study
136
between 2014 to 2017 when the children were 4.5 years of age, including a laboratory visit and
137
questionnaire measures. The analytic sample for the current study included only those
8 138
participants with complete data for the laboratory visit and questionnaire measures collected at
139
age 4.5 years (N = 107). Few dyads were excluded due to missing either the laboratory visit (n =
140
4), or questionnaire measures (n = 1), having only a male primary caregiver (n = 2), or child food
141
allergies that could not be accommodated in the mother-child snack food selections task (n = 1).
142
2.2 Procedures and Measures
143
Mother-child dyads came to the laboratory to complete a battery of behavioral tasks that
144
assessed parenting behaviors and children’s cognitive and emotional development within two
145
weeks of being 4.5 years of age. Anthropometric data (i.e., height and weight) were collected at
146
the end of the laboratory visit. Mother-child dyads were continuously video-recorded throughout
147
the laboratory visit, which lasted approximately 1.5 hours. Mothers completed questionnaire
148
measures within approximately one month of completing the laboratory visit. All study
149
procedures were reviewed and approved by the university Institutional Review Board. Mothers
150
provided written consent for their own and their child’s study participation.
151
2.2.1 Mother-child snack food selections. Mother-child snack food selections were
152
assessed approximately 20-minutes into the laboratory visit using a standardized protocol: A
153
research assistant entered the observation room to present a small, three-tiered shelf lined with
154
nine snack food options (described below) and an empty tray to the mother and child. The
155
research assistant told the dyad to select up to five snack foods for the child to have available
156
throughout the remainder of the laboratory visit (approximately one hour). The research assistant
157
exited the room while the mother and child selected snack foods and placed them on the tray.
158
Dyads took a mean of 2.48 minutes (SD = 0.81) to make their selections. After the dyad made
159
their selections, the research assistant re-entered the observation room, removed snack foods that
160
were not selected, and placed the snack tray on a table within the child’s reach. The research
9 161
assistant reminded the dyad that the selected snack foods would remain available throughout the
162
remainder of the laboratory visit and began the next task.
163
The snack food options included in this task were consistent with common options in
164
food retail settings in the United States (e.g., gas stations, convenience stores; Tester et al.,
165
2011), and with qualitative definitions of snack foods provided by mothers of preschoolers, such
166
as relatively small portions of food (Blake et al., 2015). The energy density values of the snack
167
food options were calculated from the Nutrition Facts label information and categorized
168
according to typical energy density standards (Rolls & Leahy, 2010, p. 545). The snack food
169
options were unevenly divided by energy density category to reflect the current unbalanced food
170
environment in the United States (Krebs-Smith et al., 2010) and included 6 higher-energy-
171
density snack foods (≥ 1.5 kcal/g) and 3 lower-ED snack foods (< 1.5 kcal/g). The higher-ED
172
snack foods were: chocolate candy (0.6 ounce Milky Way, 4.40 kcal/g; or 0.6 ounce Twix, 4.71
173
kcal/g); pastry (1.8 ounce Little Debbie honeybun, 4.31 kcal/g); chocolate chip cookies (1.1
174
ounce Chips Ahoy mini, 4.84 kcal/g; or 1.2 ounce Famous Amos bite size; 5.00 kcal/g); Fruit
175
Roll-up (0.5 ounce Betty Crocker, flavor varied, 3.57 kcal/g); popcorn (1 ounce SmartFood,
176
white cheddar, 5.71 kcal/g); and potato chips (1 ounce Lays, regular, 5.71 kcal/g; or 1 ounce Utz,
177
regular, 5.36 kcal/g). The lower-ED snack foods were: small, whole apple (Macintosh, 0.47
178
kcal/g); applesauce (4 ounce Mott’s, original, 0.79 kcal/g); and baby carrots (2 ounce,
179
0.44kcal/g). Snack foods were presented in the same order on the shelf for each mother-child
180
dyad. In rare cases, select snack foods were substituted (n = 5) with snack foods that were
181
comparable in energy density to accommodate child food sensitivities or allergies.
182 183
Trained research assistants recorded which snack foods were selected for the snack tray in real time (i.e., live-coded) during the task. For descriptive purposes, we calculated the number
10 184
of children who selected each snack food, and the total number of snack foods selected (any
185
energy density). For our principal analyses, we calculated the total number of higher-ED and
186
lower-ED snack foods selected.
187
2.2.2 Child snack food consumption. Trained research assistants coded video
188
recordings of the laboratory visit to indicate which snack foods, if any, the child consumed. If the
189
child consumed any amount of a snack food, ranging from a single bite to the full portion, the
190
snack food was coded as consumed. Video recordings did not allow for more precise estimates of
191
snack food consumption due to limited camera angles. For descriptive purposes, the proportion
192
of snacking occasions initiated by the child (as compared to snacking occasions initiated by the
193
mother) was calculated. For our principal analyses, we calculated the total number of higher-ED
194
and lower-ED snack foods consumed.
195
2.2.3 Observed maternal child feeding practices. Trained research assistants coded
196
mothers’ child feeding practices during the snack food selections task. Observational coding
197
schemes for child control over food choices (i.e., “child control”), encouragement of balance and
198
variety (i.e., “encourage balance”), and teaching about nutrition (i.e., “teach nutrition”) were
199
developed based on corresponding parental self-report measures of the same child feeding
200
practices (Musher-Eizenman & Holub, 2007). These child feeding practices were chosen because
201
they could be observed during snack food selection, and few studies have observed these child
202
feeding practices, particularly in the context of snacking (Blaine et al., 2017; Yee et al., 2017).
203
Observed child control indicated the degree to which the mother allowed the child to control
204
snack food selections. Coded values ranged from 0 to 4, with higher scores indicating greater
205
child control over snack food selections. Observed encouragement of balance and variety
206
indicated the degree to which the mother promoted varied and nutritious (according to the
11 207
mother’s perception) snack food selections. Coded values ranged from 0 to 2, with higher scores
208
indicating greater encouragement of balance and variety. Observed teaching about nutrition
209
indicated the degree to which the mother used didactic (i.e., instructional, informational)
210
techniques to encourage the selection of nutritious (according to the mothers’ perception) snack
211
foods. Coded values ranged from 0 to 2, with higher scores indicating greater maternal teaching
212
about nutrition. Research assistants trained on the coding schemes until they reached reliability,
213
defined as a single measures intra-class correlation coefficient (ICC) of 0.85 or higher (Hallgren,
214
2012). Approximately 20% of video-recordings (n = 25) were double-coded for reliability during
215
the final coding stage. Coders demonstrated strong reliability for all constructs (ICC ≥ 0.95). We
216
used the coded values for each observed child feeding practice in our principal analyses.
217
2.2.4 Maternal self-reported child feeding practices. Mothers completed the
218
Comprehensive Feeding Practices Questionnaire (CFPQ; Musher-Eizenman & Holub, 2007).
219
The CFPQ is a validated self-report assessment of twelve global child feeding practices (i.e.,
220
across all meals and snacks). Relevant to the current study, the CFPQ was developed with
221
parents of preschool-aged children (Musher-Eizenman & Holub, 2007), and has demonstrated
222
associations with parent-reported food preferences among 3- to 7-year olds (Vollmer & Baietto,
223
2017). Three of the CFPQ scales corresponded to the observed child feeding practices measured
224
during the snack food selections task and were included in the current study: child control over
225
food choices (5-items, α = .66), encourage balance and variety (4-items, α = .69), and teaching
226
about nutrition (3-items, α = .56). All items were assessed on a 5-point Likert scale, with higher
227
scores indicating greater endorsement of the child feeding practice. We calculated the mean
228
scores of the items corresponding to each self-reported child feeding practice for our principal
229
analyses.
12 230
2.2.5 Study covariates. Since the time elapsed since a child last ate may be associated
231
with snack food selections and consumption, it was tested as a potential study covariate. In
232
addition, prior research suggests that associations between mothers’ child feeding practices and
233
children’s eating behavior may be explained in part by maternal and child sociodemographic and
234
weight status characteristics (Bergmeier et al., 2020; McPhie et al., 2014; Patel et al., 2018).
235
Therefore, we tested the following variables as covariates: maternal age, maternal education
236
level, maternal BMI, household income, child sex, and child BMI-for-age z-score. Variables that
237
had statistically significant (p < .05) bivariate associations with mothers’ child feeding practices
238
(observed and/or self-reported), mother-child snack food selections, and/or children’s snack food
239
consumption were retained in multiple linear regression analyses predicting mother-child snack
240
food selections and children’s snack food consumption; this allowed us to estimate the amount of
241
variance explained by mothers’ child feeding practices above and beyond maternal and child
242
sociodemographic and weight status characteristics.
243
2.2.5.1 Time elapsed since the child last ate. Mothers reported the time of their child’s
244
last meal or snack prior to the laboratory visit. The number of minutes elapsed between the meal
245
or snack and the start time of the laboratory visit was calculated. Values that exceeded the 95th
246
percentile (n = 5) were Winsorized to (i.e., replaced with) the 95th percentile value. Two missing
247
values were assigned the Winsorized mean, resulting in a sample mean of 111.78 minutes (SD =
248
62.86, min = 20.00, max = 267.00). The number of minutes elapsed since the child last ate (i.e.,
249
“child last ate”) was treated as a continuous variable in the analyses.
250
2.2.5.2 Maternal BMI. Trained research assistants measured mothers’ height (measured
251
at child age 6 months) and weight (measured at child age 4.5 years) using a standard stadiometer
252
(Seca 213) and scale (Tanita UM-080). Maternal BMI was calculated from height and weight
13 253
(kg/m2) and treated as a continuous variable in the analyses. Mothers who were pregnant (n = 5)
254
were excluded from the analytic sample in all analyses including maternal BMI.
255
2.2.5.3 Child BMI-for-age z-score. Trained research assistants measured child height and
256
weight at child age 4.5 years using a standard stadiometer (Seca 213) and scale (Tanita UM-
257
080). Child weight, height, sex, and age on the date of measurement were entered into the U.S.
258
Centers for Disease Control and Prevention (CDC) SAS program (2016) to calculate child BMI-
259
for-age z-scores (BMIz) according to the 2000 growth charts (Kuczmarski et al., 2002). Child
260
BMIz was treated as a continuous variable in the analyses.
261
2.3 Analyses
262
As preliminary analyses, we calculated descriptive statistics (e.g., means, standard
263
deviations (SD), frequencies) for participant sociodemographic and weight characteristics and all
264
study variables. We also conducted Pearson correlations to explore bivariate associations among
265
all potential covariates and study variables. For our principal analyses, we first conducted
266
Pearson correlations to explore the correspondence between observed and self-reported measures
267
of mothers’ child feeding practices. Next, we conducted multiple linear regression analyses to
268
explore how mothers’ child feeding practices (observed and self-reported) were associated with
269
mother-child selections, and child consumption, of higher-ED and lower-ED snack foods. There
270
was no evidence of multicollinearity (all variance inflation factors ≤ 2) in the regression
271
analyses. Analyses were conducted using SPSS version 24 (IBM Corporation, 2016). Results
272
were considered statistically significant at p < .05.

3. Results 3.1 Preliminary Analyses Participant characteristics are presented in Table 1. The majority of mothers identified as
276
non-Hispanic, White and were married. Children were evenly represented by sex and were
277
primarily non-Hispanic, White. The prevalence of obesity among mothers (n = 30, 28%) and
278
children (n = 11, 10%) was consistent with national averages in the United States (Flegal et al.,
279
2016; Skinner et al., 2018).
280
Descriptive statistics on mother-child snack food selections and child snack food
281
consumption are presented in Table 2. The majority of dyads (n = 85, 79%) selected the
282
maximum of 5 snack foods (min = 1, max = 5). Chocolate chip cookies were the most commonly
283
selected snack food (n = 73, 68%), followed by applesauce (n = 68, 64%), apple (n = 59, 55%),
284
chocolate candy (n = 57, 53%), fruit roll-up (n = 57, 53%), popcorn (n = 52, 49%), carrots (n =
285
48, 45%), potato chips (n = 42, 39%), and honeybun (n = 37, 35%).
286
Approximately two-thirds of children (n = 67, 63%) consumed at least one snack food
287
(any amount) during the one-hour observation period following snack food selections. The fruit
288
roll-up was the most commonly consumed snack food (n = 25, 23%), followed by apple (n = 22,
289
21%), chocolate chip cookies (n = 21, 20%), applesauce (n = 18, 17%), popcorn (n = 14, 13%),
290
chocolate candy (n = 13, 12%), honeybun (n = 8, 8%), carrots (n = 7, 7%), and potato chips (n =
291
7, 7%). Among children who consumed any snack foods, children initiated the vast majority of
292
snacking occasions (Mproportion = 0.88, SD = 0.31, min = 0.00, max = 1.00); children were the sole
293
initiators of snacking occasions in most dyads (82%).
294 295
3.1.1. Covariate associations. There were several small, statistically significant bivariate associations involving potential covariate variables (see Table 3). There were no statistically
15 296
significant associations involving household income, child sex, or child BMI-for-age z-score (p >
297
.05; data not shown). Therefore, we retained the time elapsed since the child last ate, maternal
298
age, maternal education, and maternal BMI as covariates in the multiple regression analyses
299
predicting mother-child snack food selections and children’s snack food consumption. In
300
addition, these preliminary analyses revealed that the number of higher-ED and lower-ED
301
density snack foods selected had small correlations with the number of these snacks foods that
302
children consumed (see Table 3). Therefore, we also included the number of higher-ED and
303
lower-ED snack foods selected as a covariate in the multiple linear regression analysis predicting
304
children’s consumption of snacks foods corresponding in energy density.
305
3.2 Principal Analyses
306
Results of the Pearson correlation analyses testing associations between the observational
307
and self-report assessments of mothers’ child feeding practices are presented in Table 3. Notably,
308
observed child control over food choices was not correlated with self-reported child control (r =
309
0.02, p = .842). On the other hand, observed encouragement of balance and variety and observed
310
teaching about nutrition had small, positive correlations with their corresponding self-report
311
measures (r = 0.21, p = .030, and r = 0.24, p = .013, respectively).
312
Results of the multiple linear regression analyses for mother-child snack food selections
313
and child snack food consumption are presented in Table 5 and Table 6, respectively. Only the
314
models predicting higher-ED snack food selections (R2 = 0.22, F = 2.56, p = .009) and lower-ED
315
snack food selections (R2 = 0.19, F = 2.13, p = .030) were statistically significant. Regarding
316
higher-ED snack food selections, mother-child dyads tended to select more higher-ED snack
317
foods when mothers were observed to give children higher levels of control over food choices,
318
and when mothers reported higher levels of teaching about nutrition. Specifically, each one-unit
16 319
in increase observed child control (measured on a 0 to 4 scale) was associated with selecting 0.35
320
more higher-ED snack foods (SE = 0.12, p = .006). Each one-unit increase in self-reported
321
teaching about nutrition (measured on a 1 to 5 scale) was associated with selecting 0.49 more
322
higher-ED snack foods (SE = 0.19, p = .010). Dyads tended to select fewer higher-ED snack
323
foods when mothers self-reported higher encouragement of balance and variety: Each one-unit
324
increase in self-reported encouragement of balance and variety (measured on a 1 to 5 scale) was
325
associated with selecting 0.66 fewer higher-ED snack foods (SE = 0.24, p = .007). Regarding
326
lower-ED snack food selections, dyads tended to select more lower-ED snack foods when
327
mothers self-reported higher encouragement of balance and variety. Specifically, each one unit
328
increased in self-reported encouragement of balance and variety was associated with selecting
329
0.53 more lower-ED snack foods (SE = 0.20, p = .008).
330
4. Discussion
331
Preschool-aged children the United States tend to consume high-energy-density foods
332
during snacking occasions (Deming et al., 2017; Shriver et al., 2018; Welker et al., 2018). Given
333
concerning evidence linking children’s consumption of high-energy-density foods to lower
334
dietary quality (Kachurak et al., 2019) and higher childhood obesity risk (Vernarelli et al., 2011),
335
it is critical to identify factors that reduce preschoolers’ selection and consumption of higher-
336
energy-density foods, and promote their selection and consumption of lower-energy density
337
foods during snacking occasions. Considering parents’ proximal influence on preschoolers’
338
eating behaviors (Savage et al., 2007; Scaglioni et al., 2018), the current study explored
339
associations among mothers’ child feeding practices (observed and self-reported), mother-child
340
snack food selections, and children’s snack food consumption in a laboratory setting.
17 341
For our first aim, we explored the correspondence between mothers’ child feeding
342
practices observed during a mother-child snack food selection task in the laboratory, and
343
mothers’ self-reported global child feeding practices (i.e., across meals and snacks). We found a
344
small degree of positive correspondence in the observed and self-reported measures of
345
encouragement of balance and variety and teaching about nutrition, and no correspondence in the
346
observed and self-reported measures of child control over food choices. These results add to
347
existing literature demonstrating inconsistencies between observational and self-report measures
348
of child feeding practices during meals (Bergmeier et al., 2015; Farrow et al., 2011; Fries et al.,
349
2019). To our knowledge, the current study is among the first to compare observational and self-
350
report measures of encouragement of balance and variety and teaching about nutrition. Our
351
results demonstrated that mothers were somewhat consistent in their use of encouragement of
352
balance and variety and teaching about nutrition during snack food selections (observed) and
353
globally across meals and snacking occasions (self-reported). These findings highlight the need
354
for additional research on how parents develop these child feeding practices, as their consistent
355
use (or non-use) across meals and snacking occasions may compound their effects on children’s
356
dietary quality and obesity risk over time (Yee et al., 2017).
357
The null association between observed and self-reported child control over food choices
358
is consistent with a prior study conducted with parents of 1-to-3-year olds, which found that
359
observed and self-reported measures of allowing children to choose foods during meals had
360
among the lowest consistency of the child feeding practices they assessed (Fries et al., 2019).
361
There are a few possible explanations for the lack of an association between observed and self-
362
reported measures of child control over food choices in the current study. This finding may
363
reflect differences in the context of measurement: Mothers may exert different levels of control
18 364
over snack food selection compared to globally across all meals and snacks, as suggested by a
365
qualitative study of parents of preschool-aged children (Loth, Uy, et al., 2018). Alternatively, it
366
may be that mothers underestimate the extent to which they grant their children control over food
367
choices when asked in a questionnaire. However, this explanation is limited by the differences in
368
the context of measurement. As a third explanation, it may be that in observed assessments,
369
mothers are responding to their children’s desires in-the-moment, allowing children more control
370
while also giving them information about their choices in a more covert effort to guide food
371
selection (Stifter & Moding, 2019). Future studies should continue to explore reasons for
372
agreement or disagreement between observed in-the-moment and global maternal self-report
373
assessments of child control, including agreement between observed and self-report assessments
374
that are both specific to snacking.
375
For our second aim, we explored how mothers’ child feeding practices (observed and
376
self-reported) were associated with mother-child snack food selections and children’s snack food
377
consumption. We found that mothers’ child feeding practices explained a small amount of
378
variance of selections of both higher-energy-density and lower-energy-density foods, above and
379
beyond covariates. However, mothers’ child feeding practices did not explain a statistically
380
significant amount of variance in children’s consumption of higher-energy-density or lower-
381
energy-density foods during the one-hour observation period following snack food selections.
382
The relatively small amount of variance explained by our multiple linear regression models is
383
consistent with nutrition research examining complex health outcomes, such as child feeding
384
practices, and suggest that unmeasured factors affected snack food selection and consumption
385
(Pounis, 2019).
19 386
With regard to snack food selections, mother-child dyads selected more higher-energy-
387
density snack foods when mothers were observed to give children greater control over the snack
388
food choices. This finding is consistent with a previous study of parents of 3- to 12-year-olds,
389
which found that the mean energy content of a hypothetically selected fast food meal was higher
390
when parents self-reported greater child control over food choices (Wellard et al., 2014). The
391
positive association between observed child control over food choices and higher-energy-density
392
snack food selection may be explained by children’s natural preferences for foods that are higher
393
in energy density (Anzman-Frasca et al., 2018; Birch, 1999). Recent evidence for this preference
394
has come from a hypothetical food choice study in which children aged 3 to 14 years rated
395
higher-energy-density foods as more preferred than lower-energy-density foods (Potter et al.,
396
2017). Mothers’ self-reported global child control over food choices, however, was not
397
associated with the energy density of mother-child snack food selections. This inconsistency
398
suggests that children’s in-the-moment control over food choices was more salient to snack food
399
selections than the amount of control children generally have over their food selections across
400
meals and snacks. This may be explained by differences in the level of child control mothers’
401
grant children during snacking occasions versus their more global practices across meals and
402
snacks, as suggested by the null bivariate association we found between these two measures.
403
Alternatively, this finding may reflect differences in the timescale of measurement; observed
404
child control and mother-child snack food selections were assessed simultaneously, whereas
405
mothers self-reported global child control was assessed within one-month of the laboratory visit.
406
Mother’s self-reported encouragement of balance and variety had favorable associations
407
with the energy density of dyads’ snack food selections. These findings are among the first to
408
show an association between mother’s encouragement of balance and variety and mother-child
20 409
snack food selections of lower-energy-density snack foods, and complement existing research
410
demonstrating similar associations between higher global encouragement and balance and
411
variety and children’s lower consumption of higher-energy-density snacks foods (Gevers et al.,
412
2015), and children’s higher consumption of fruits and vegetables (Shim et al., 2016). The null
413
associations between observed encouragement of balance and variety and snack food selections
414
may suggest that mothers’ global use of this practice was more salient to dyads’ snack food
415
selections than their in-the-moment use of this practice. The favorable associations between
416
mothers’ self-reported global encouragement of balance and variety, and the energy density of
417
dyads’ snack food selections may be explained by social influences on children’s eating behavior
418
over time, as parental encouragement can influence children’s food choices despite children’s
419
preferences for high-energy-density foods (see Scaglioni et al., 2018 for a review).
420
In contrast, when mothers self-reported higher teaching about nutrition, dyads tended to
421
select more higher-energy-density snack foods. Again, this finding is among the first to show an
422
association between mothers’ teaching about nutrition and mother-child snack food selections of
423
high-energy-density snack foods, and in some respects complements existing research
424
demonstrating positive associations between restrictive child feeding and children’s consumption
425
of high-energy-density snack foods (Boots et al., 2018; Corsini et al., 2018; Fisher & Birch,
426
1999). However, observed teaching about nutrition had an opposite, marginally significant
427
negative association with higher-energy-density snack food selections. Associations between
428
teaching about nutrition and snack food selections may depend on how mothers contextualize
429
their nutrition education messages to children. For example, mothers may teach children about
430
food in the context of weight loss, which has been associated with negative child eating behavior
431
outcomes such as early dieting (Balantekin et al., 2014). Or, mothers may teach children about
21 432
foods in the context of supporting healthy growth and active play, which has been linked to
433
positive effects on children’s eating behavior such as increasing children’s liking and intake of
434
lentils (a lower-energy-density food; Ramsay et al., 2017). Additional research on how mothers
435
frame their nutrition education messages to children would help clarify associations between
436
teaching about nutrition and children’s snacking behavior.
437
Regarding children’s snack food consumption, we found that the child feeding practices
438
we assessed in this study using both observed and self-reported measures explained little
439
variance in children’s consumption of higher- or lower-energy-density snack foods. These
440
findings are in contrast to prior studies that have linked parent self-report measures of child
441
control, encouragement of balance and variety, and teaching about nutrition to parent-reported
442
child consumption of higher-energy-density and lower-energy-density foods (Chaidez et al.,
443
2014; Gevers et al., 2015; Shim et al., 2016). Our conflicting findings may be explained by
444
differences in assessment approaches for child feeding practices and/or children’s snack food
445
consumption, and by differences in sample characteristics across studies. Interestingly, children’s
446
consumption of higher- and lower-energy density snack foods had a medium bivariate
447
association in the current study, which suggests that children who consumed snack foods were
448
more interested in snacking generally than considering the energy density of the snack foods.
449
Additionally, although children’s hunger levels were not measured in the current study, the
450
amount of time elapsed since the child’s last meal or snack was not associated with child snack
451
food consumption. This finding provides additional evidence that most preschoolers will
452
consume at least some amount of snack foods when they are available, which is consistent with
453
existing research showing high rates of eating in the absence of hunger among preschool-aged
454
children (Corsini et al., 2018; Harris et al., 2014). Taken together, these findings support recent
22 455
calls for additional research on associations between children’s appetitive traits and snacking
456
behavior (see Kral et al., 2018 and Porter et al., 2018), particularly given that child sex and BMI
457
were also not associated with snack food selections or consumption in the current study.
458
4.1 Strengths, Limitations, and Future Directions
459
This study has several strengths and a few notable limitations. A primary strength is our
460
use of observational measures to assess mothers’ child feeding practices, mother-child snack
461
food selections, and children’s snack food consumption. Observational measures overcome some
462
limitations of self-reported measures of child feeding practices and eating behavior (e.g., social
463
desirability and recall bias), and allowed us to compare participants under the same conditions
464
(e.g., standardized snack food options and duration of time for consumption), which strengthens
465
the validity of our results (Bruemmer et al., 2009; Pesch & Lumeng, 2017). At the same time,
466
our findings are limited to behaviors that occurred in a laboratory setting, which may not
467
generalize to behaviors in more typical contexts, such as homes or food retail locations. For
468
example, mothers and children may have behaved atypically due to being video recorded and/or
469
having few other competing demands for their attention during the snack food selection task.
470
Further, we focused on child feeding practices that could be observed during the snack food
471
selection task and had corresponding self-report measures on the Comprehensive Feeding
472
Practices Questionnaire (Musher-Eizenman & Holub, 2007). Additional insight could be gained
473
in studies investigating a broader range of child feeding practices (e.g., child involvement in food
474
preparation, maternal role modeling) in the context of snacking.
475
There are other unmeasured factors that may have impacted the total number of higher-
476
energy-density and lower-energy-density snack foods selected and/or consumed in this study.
477
We did not assess children’s liking of the snack food options, children’s perceptions of the taste
23 478
or sensory properties of the snack food options, or children’s hunger levels, although we did
479
assess the time elapsed since the child had last eaten. The snack food options were unevenly
480
divided by energy density category to reflect the current food environment (Krebs-Smith et al.,
481
2010) such that more higher-energy-density snack foods were available for selection than lower-
482
energy-density snack foods; this unequal division may have increased the number of higher-ED
483
snack foods that mother-child dyads selected by chance alone, and prevented us from comparing
484
mother-child snack food selections and children’s consumption between energy density
485
categories. The precise amount of each snack food consumed was not measured and could not be
486
assessed retrospectively from video recording due to limited camera angles, which prohibited
487
more detailed analyses of child snack food consumption such as caloric or macronutrient intake.
488
Despite this limitation, our observational assessment overcomes some of the limitations
489
associated with parent-reported food frequency questionnaires (e.g., recall bias), which are
490
among the most common assessments in the existing literature on children’s snacking behavior
491
(Blaine et al., 2017). Lastly, mothers were the only primary caregivers represented in this
492
sample, and most participants identified as non-Hispanic, White. Additional research is needed
493
to test the generalizability of these findings in samples that are more diverse in
494
sociodemographic characteristics.
495
5. Conclusions
496
Snacking occasions are an area of opportunity to reduce children’s dietary energy
497
density, which may in turn improve overall dietary quality and decrease childhood obesity risk
498
(Dunford & Popkin, 2018). The results of this exploratory, laboratory-based study revealed that
499
mothers’ child feeding practices were associated with mother-child selections of higher-energy-
500
density and lower-energy-density snack foods, but not children’s consumption of these snack
24 501
foods. Associations with snack food selections varied depending on whether mothers’ child
502
feeding practices were assessed using an observational measure administered while dyads
503
selected the snack foods, or using a self-report measure of mothers’ global child feeding
504
practices (i.e., across all meals and snacks). Further, mothers’ child feeding practices (both
505
observed and self-reported) explained a relatively small amount of variance in the selection of
506
higher-energy-density and lower-energy-density snack food selections, suggesting that other
507
factors influence snack food choices. Future studies should continue to explore how parents’
508
child feeding practices and other factors (e.g., child appetitive traits) influence preschool-aged
509
children’s snacking behavior.
