Abstract
29
Background Children exposed to gestational diabetes mellitus (GDM) in utero are at
30
high-risk of obesity. Given that nutritional habits can track from infancy to childhood, the
31
aim of this study was to evaluate the association between the timing of fruit juice
32
introduction in infancy and later consumption of sweet-tasting foods and beverages
33
among children exposed (GDM+) and unexposed (GDM-) to GDM. Methods A total of
34
107 GDM+ and 59 GDM- participated in the project. Data on the timing of fruit juice
35
introduction during infancy were retrospectively collected for 62 GDM+ and 32 GDM-
36
children. Current dietary intakes were collected with two 24-hour dietary recall
37
questionnaires. Children were divided into groups according to the median timing of
38
juice introduction (9 months). Results Mean age of children was 6.3±2.6 and 7.6±3.7
39
years for GDM+ and GDM- children, respectively (p=0.08). Mean age of fruit juice
40
introduction was similar between groups (p>0.05). Consuming >1 serving of fruit juice
41
per day was 2.72 times more prevalent among GDM+ children introduced to fruit juice
42
<9 months, compared to GDM+ children introduced ≥9 months (CI: 1.19-6.20). This
43
association was not observed in the GDM- group. The timing of fruit juice introduction
44
was not associated with later consumption of sweets, desserts and sweet-tasting
45
beverages when adjustment for children’s age was made among GDM+ and GDM-
46
children. Conclusion Early introduction of fruit juice in infant diet is associated with
47
higher prevalence of consumption of >1 serving of fruit juice per day in GDM+ children.

Introduction
50
Children born to mothers with gestational diabetes mellitus (GDM) are at high risk of
51
developing obesity and type 2 diabetes later in life (1, 2). There is a lack of effective
52
postnatal strategies to prevent these complications among these high-risk children (3)
53
although it is well established that healthy lifestyle behaviours are associated with a
54
reduced risk of obesity among children in the general population (4). On the other hand,
55
despite efforts made to promote a healthy diet among children, consumption of high
56
amounts of ultra-processed foods and beverages rich in free sugar, like fruit juice, sugar-
57
sweetened beverages (SSB), pastries and candies is highly prevalent among Canadian
58
children (5).
59
Preference for sweetness is innate among newborns and this preference generally remains
60
during childhood (6). However, pre- and postnatal experiences, like exposure to different
61
flavors during in utero and early postnatal periods, can modulate taste preferences (7).
62
The introduction of complementary foods in the infant diet represents also a critical
63
period for flavor experiences in early life, particularly among non-breastfed children that
64
have been exposed since birth to only the flavour of formula (8). Moreover, increasing
65
evidence suggests that food preferences in children would depend on foods offered and
66
the context of feeding during early life (8). In fact, both healthy and unhealthy dietary
67
patterns established during infancy can track into childhood (9). Accordingly, some
68
authors evaluated the association between SSB and fruit juice consumption in infancy
69
and their later consumption in childhood and found that consumption of these types of
70
beverages in early life was positively associated with their consumption during childhood

(10, 11). However, to our knowledge, no such study has been conducted among children
72
exposed to GDM in utero. Given their in utero exposure to an environment rich in
73
glucose, it is possible that taste development in these children could differ from children
74
unexposed to GDM, particularly developmental preferences for sweet tasting foods,
75
which could impact food habits. In fact, previous research has shown that fetal
76
environment could be involved in food preferences programming (12).
77
While it is well recognized that SSB have a negative impact on children’s health (13),
78
fruit juice is generally considered a healthier food option by parents. In fact, 100% fruit
79
juice is considered as a serving of fruits in the 2007 Canada’s Food Guide, which could
80
encourage parents to introduce fruit juice early in their infant’s diet (14), without
81
consideration for the sweet taste of this type of beverage. Thus, given that food habits
82
could track from infancy to childhood (15, 16), and in order to identify new targets for
83
prevention of obesity development among children exposed (GDM+) to GDM in utero,
84
the primary objective of this study was to evaluate the association between early
85
introduction of fruit juice during infancy and childhood consumption of sweet-tasting
86
foods and beverages among GDM+ children. Secondly, we evaluated the association
87
between early introduction of fruit juice and childhood consumption of sweet-tasting
88
foods and beverages among a group of children unexposed (GDM-) to GDM in utero, in
89
order to compare results between groups.

All subjects were participants in a cohort study that aims to evaluate the impact of GDM
93
on mother’s and children’s health and to examine whether a healthy postnatal
94
environment could attenuate the adverse consequences of in utero exposure to GDM.
95
This study takes place at the Institute of Nutrition and Functional Foods (INAF), at Laval
96
University (Quebec City, Canada), and recruits women with and without a history of
97
GDM and their children. Participants were recruited from a previous project conducted
98
by our research team that has been previously described (17). Additionally, recruitment is
99
conducted through access to medical records from the two major hospitals with a
100
neonatal care unit in the metropolitan area of Quebec City (Hôpital Saint-François
101
d’Assise and Centre Hospitalier de l’Université Laval-CHUL). Recruitment is also
102
conducted by emails sent to Laval University community as well as posts on healthcare
103
websites and on social media (Facebook). Children with a history of in utero exposure to
104
GDM between 2003 and 2013 are included in the study and children exposed to type 1 or
105
type 2 diabetes are excluded. Children from the control group had to be born to a mother
106
that never have had diabetes (Type1, 2 or GDM) before or after the index pregnancy. To
107
date, a total of 107 children exposed (GDM+) and 59 children unexposed (GDM-) to
108
GDM in utero have participated in the project. Written consents were obtained from all
109
participating mothers and children and ethical approval was obtained from the Laval
110
University Ethics Committee (2011-196-A-4 R-3) and from the Centre Hospitalier
111
Universitaire de Québec Ethics Committee (2015-2031). This study is registered in the

Children came with their mother to the INAF research center for a single 1-hour visit.
115
During this visit, data about the timing of fruit juice introduction were retrospectively
116
collected by a self-administrated questionnaire completed by the mother of each child.
117
Mothers were asked when their child drank fruit juice, defined as 100% pure juice, for
118
the first time (infant age given in months and/or weeks). A randomly selected subsample
119
of participants (n=20) completed this questionnaire for a second time at home, within a 2
120
weeks interval between each completion, in order to evaluate the reliability of answers
121
given for this questionnaire. Results of the reliability test showed a strong correlation
122
between answers given for the completion of both infant feeding questionnaires (r=0.81,
123
p < 0.001).
124
Outcomes
125
In order to estimate current dietary intakes of children, a 24-hour dietary recall (24HDR)
126
was conducted with a trained dietitian using the 5 steps of the Automated Multiple-Pass
127
Method (AMPM): 1) quick list of the food items consumed 2) reminder of the food items
128
frequently forgotten 3) time and type of meals 4) details about serving size consumed,
129
brand name of commercial products, ingredients and methods of homemade foods 5)
130
review of the dietary recall (18). All food and drink items consumed in the previous day,
131
from midnight to midnight, were recorded. Three-dimensional food models were used to
132
enhance accuracy of portion size estimates. Mothers of children younger than 10 years
133
were asked to complete the 24HDR whereas children were present during the interview
134
and were asked to add information if needed (i.e. for food consumed outside home). For
135
children ≥10 years, the 24HDR was completed directly by the child, with the help of the
136
mother if needed (i.e. for food preparation details). A second 24HDR was completed over

the phone with the mother following the same validated method, the AMPM (18), 7-10
138
days after their visit. Mean intakes for the two questionnaires were used in analyses.
139
Dietary intake data were analyzed using Nutrition Data System for Research (NDSR)
140
(19, 20). From this software, reports can be extracted by nutrients or by food group
141
categories for each participant. In order to extract data regarding sweet-tasting foods and
142
beverages, the Nutrition Coordinating Center (NCC) Food Group Count System from
143
NDSR was used (19, 20). The NCC Food Group Count System is composed of 9 groups
144
and 168 subgroups of foods, based on recommendations made by the Dietary Guidelines
145
for Americans and the USDA Food Guide Pyramid. For the purpose of this study, groups
146
and subgroups of foods containing high amount of sugar (21) or known for their sweet
147
taste were extracted and compiled together to form 4 foods and beverages groups. These
148
groups were used in analyses, with a description of a portion size provided bellow:

Children were categorised as non-consumers (0 serving/d), consumers (>0 serving /day)
160

161
groups described above.
162
Statistical analyses
163
Descriptive statistics were calculated as mean ± standard deviation (SD) or as percentage
164
(%). Participant’s characteristics and dietary intakes during childhood of GDM+ and
165
GDM- children were compared using Student t-test, Chi-squared test (χ2) or Fisher’s
166
exact test (when cell number was <5). GDM+ and GDM- children were divided into
167
groups according to the median timing of fruit juice introduction during infancy, which
168
was 9 months. Fisher’s exact test and χ2 test were performed to evaluate the distribution
169
of children across different groups of consumers and high consumers of sweet tasting
170
food and beverages among GDM+ and GDM- children. Finally, prevalence ratios (PR)
171
using log binominal model were calculated to evaluate the prevalence of consumers and
172
high consumers of food items from the different food groups in children introduced to
173
fruit juice before 9 months compared to those introduced at 9 months or later among
174
GDM+ and GDM- children. Given the low prevalence of children who consumed >1
175
serving of STB per day in both groups, the PR of high consumption of STB was not
176
computed. Finally, stepwise regression analyses were performed to determine which
177
cofactors should be included in the adjusted models among the following: breastfeeding
178
duration, timing of solid food introduction, children’s sex and age, maternal education
179
level and family incomes. Accordingly, analyses were only adjusted for children’s age.
180
The p value ≤0.05 and confidence interval (CI) of 95% were used to identify statistically
181
significant results. SAS software, version 9.4, was used for analyses.

Results
183
A total of 107 GDM+ and 59 GDM- children were recruited, but only 62 GDM+ and 32
184
GDM- children had complete information regarding the timing of fruit juice introduction.
185
Within the subsample with missing information, 9 mothers did not answer the specific
186
question regarding the timing of fruit juice introduction and 63 gave the answer “I don’t’
187
know” to this question. Thus, analyses included the 94 children with complete
188
information. Among GDM+ children without data on fruit juice introduction (n=45), a
189
lower proportion had been breastfed compared to children included in analyses (80%
190
compared to 95%, p=0.03). However, there was no difference regarding children’s age
191
and sex, maternal education level, family incomes and the timing of solid food
192
introduction (results not shown). There was also no statistically significant difference in
193
characteristics of GDM- children included and excluded from analyses. Characteristics of
194
the 94 participating children are presented in Table 1. Overall, 77 % and 78% of GDM+
195
and GDM- children received fruit juice during the first year of life, respectively.

The group “yes” refers to children who reported having consumed any amount of items from the specific food group. Fruit juice includes citrus and non-citrus 100% pure juice; sweet-tasting beverages (STB) include sweetened and artificially sweetened soft drinks, fruit drinks, tea and water; sweets include sugar, syrup, honey, jam, molasses, fudge, caramel, chocolate syrup, candy, chocolate candy, gum drops, frosting or glaze and sweetened flavored milk beverage powder; desserts include cakes, cookies, pies, pastries, danish, doughnuts and cobblers. P value was calculated with χ2 analyses and with Fisher’s exact test when cell number was <5.
238
As seen in Table 4, GDM+ children introduced to fruit juice before 9 months did not
239
have different PR for the consumption of any amount of fruit juice, sweets and desserts
240
compared to GDM+ children introduced to fruit juice ≥ 9 months. However, consuming
241
more than 125 ml of fruit juice per day was 2.72 times more prevalent among GDM+
242
children introduced to fruit juice before 9 months, compared to those introduced at 9
243
months or later (CI: 1.19-6.20). Although prevalence of consumption of any amount of
244
STB in the crude model was 2.11 higher for GDM+ children exposed to fruit juice earlier
245
(CI: 1.02-4.34, result not shown), this latter was no longer statistically significant after
246
adjustment for children’s age (PR: 1.43, CI: 0.85-2.42, Table 4). Among GDM- children,
247
the prevalence for the consumption of any amount or for >1 serving of any food and
248
beverage groups was similar according to the timing of fruit juice introduction (Table 4).

Discussion
260
This study showed that early introduction of fruit juice during infancy, defined as before
261
9 months of age, is associated with a higher odds of consuming sweetened and artificially
262
sweetened beverages and high amounts of fruit juice during childhood among GDM+
263
children. The association between the timing of fruit juice introduction and odds of

consuming >125 ml of fruit juice per day remained statistically significant after
265
adjustment for children’s age, but the association between fruit juice introduction and
266
later consumption of STB was no longer statistically significant after adjustment for
267
children’s age. Among GDM- children, no statistically significant association between
268
the timing of fruit juice introduction and consumption of sweet-tasting food and
269
beverages during childhood was observed.
270
Results of this study suggest that the prevalence of consumption of more than 1 serving
271
of fruit juice per day was higher among GDM+ children exposed to fruit juice before 9
272
months compared to those exposed to juice at or after 9 months. To our knowledge, this
273
is the first study that evaluated the association between early life nutrition and food and
274
beverage intakes during childhood among GDM+ children, which limits comparison of
275
these results with the current literature. However, few studies conducted in the general
276
population that investigated the association between SSB or juice intakes in infancy and
277
beverage consumption in childhood showed similar results that these found in the GDM+
278
group (10, 11). Analyses from the Infant Feeding Practices Study II (IFPS II), a national
279
longitudinal study conducted in the United-States, showed that consuming SSB during
280
the first year of life was associated with an increased risk of consuming SSB more than
281
one time per day at the age of 6 years (10). In addition, Sonneville et al. showed that
282
higher intakes of fruit juice at the age of 12 months was associated with a higher
283
consumption of fruit juice and SSB in both early and mid-childhood when compared to
284
infant that did not consume any amount of fruit juice at 12 months (11). More

much juice per day during childhood compared to those that did not consume any amount
287
of juice at 1 year (2.4 vs 1.2 servings per day) (11).
288
Our study showed no statistically significant association between the timing of fruit juice
289
introduction during infancy and later consumption of foods containing high amount of
290
sugar among GDM+ children. To our knowledge, no study has evaluated the association
291
between juice introduction in infancy and later consumption of sweet foods in children
292
exposed or unexposed to GDM in utero. However, Rose et al. evaluated the association
293
between dietary patterns in early life and dietary patterns in childhood using data from
294
the IFPS II (9). This study showed that infants having a high density energy diet at 9
295
months, which included high amounts of juice, sweet foods and French fries, were greater
296
consumers of SSB, sweet desserts and fried potatoes at 6 years, compared to other dietary
297
patterns in infancy (9). Liquid and solid foods have different properties. Indeed, sugars
298
from liquid sources are associated with less satiety compared to sugar from solid foods,
299
mainly due to the different fiber content (22). However, we are unaware of any published
300
study evaluating the influence of the food matrix on taste development, thus it is unclear
301
whether sugar intake from juice could affect taste preference for sugar from solid foods
302
the same way that for sugar from liquids.
303
Furthermore, this study showed no statistically significant association between the timing
304
of fruit juice introduction and later consumption of sweet tasting food and beverages
305
among GDM- children. The lack of association in the control group, which is not in
306
agreement with studies conducted in the general population (9-11), could possibly be
307
explained by the small number of participants in the GDM- group, which limits the
308
statistical power to detect statistically significant results.

The association between the timing of fruit juice introduction in infant diet and beverages
310
consumption in childhood among GDM+ children could be explained in part by the
311
development of taste preferences in early life. As mentioned earlier, it has been
312
demonstrated that taste preferences track from infancy to childhood and that the early life
313
period could be a critical moment to program children’s dietary habits (8). In fact,
314
nutritional experiences in early life have neurological programing effect that influence
315
eating behaviour later in life (23). A study conducted in mice that evaluate the
316
neuroanatomical development of the olfactory system showed that exposure through
317
mother’s milk to odours that activate GFP-tagged olfactory receptors was associated with
318
larger glomeruli in the olfactory bulb and with significant preferences for the activating
319
odour (24). These results suggest that exposure to specific flavours during early life result
320
in enhanced detection of these learned odours, which could facilitate their acceptance by
321
children. Among studies conducted in humans, Pepino et al. demonstrated that infants
322
who were routinely fed with sweet water in early life preferred high levels of sucrose in
323
childhood, compared to those who were not routinely fed with sweet water in infancy,
324
highlighting the impact of early exposure to sweet on modulation of taste preference for
325
sweetness (25). However, even if the early life period is recognized as critical for the
326
development of taste preferences, the exact timing to shift taste preferences is still
327
unknown (26). In order to answer this gap, a randomized clinical trial has been conducted
328
among formula-fed infants to test whether the timing of introduction of protein
329
hydrolysate formulas (PHF), known for their particularly unpleasant flavour, in infant
330
diet would influence its acceptance later in infancy (27). This study showed that infant
331
exposed to PHF earlier (i.e. at 1.5 and 2.5 months) consumed significantly more amount

ACCEPTED MANUSCRIPT
of PHF at 7.5 months compared to infants exposed later (i.e at 3.5 months) (27). Infants
333
exposed to PHF at 3.5 months consumed the same amount of PHF at 7.5 months as
334
infants from the control group who were fed with cow-milk base formulas (27). Thus,
335
authors suggested that the window of opportunity to modulate taste preferences could
336
start to close as early as 3.5 months.
337
Although we first hypothesized that early introduction of fruit juice in the infant diet
338
would lead to an increased consumption of sweet-tasting foods and beverages, we only
339
found associations with beverage intakes. As mentioned above, it is possible that the food
340
matrix of juice, a liquid with no fiber, would influence differently the consumption of
341
beverages and solid foods because of their different properties (22). Furthermore, in
342
addition to the taste preference theory, it has been suggested that fruit juice intake in
343
infancy could be a gateway to later consumption of caloric beverages by establishing the
344
habit of consuming these types of drinks (11). Similarly, the association between the
345
timing of fruit juice introduction and its later consumption could also be explained by
346
dietary habits established by parents during infancy that could remain during childhood.
347
In fact, it is possible to think that parents continue to feed their children the same types of
348
food from infancy to childhood, explaining associations seen for beverages but not for
349
foods.
350
Our study presents some limitations. First, given the cross-sectional study design, the
351
timing of fruit juice introduction was retrospectively collected. This did not allow us to
352
quantify the amount of juice intakes in infant diet neither the frequency of consumption
353
during this period, which can have an impact on taste development and dietary habits.
354
This study design is also at risk of recall bias, although our reliability test showed a

strong correlation between answers given for the two completed questionnaires.
356
Furthermore, mothers had the possibility to answer “I don’t know” to the question
357
regarding the timing of juice introduction, which reduces risk of recall bias in our
358
analyses. In fact, it is possible to think that mothers that answered this question were
359
confident of their answer. However, this study should be repeated using a prospective
360
study design in order to limit this bias. Another limitation of the study is its small sample
361
size, in both the GDM+ and GDM- groups, which increases the likelihood of type 2 error.
362
Indeed, given the small sample size of participants in the control group (n=32), it is
363
possible that the lack of association observed in this group is due to low statistical power.
364
Furthermore, the homogeneity of participant’s characteristics (high income families with
365
high education level) restricts our results to this study population only. Finally, this study
366
did not evaluate specifically taste preferences of children, which limits interpretation of
367
these results. In fact, Divert et al. showed that consumption of sweet tasting foods and
368
beverages was not clearly associated with sweet liking, evaluated using a liking score, in
369
a cohort study of school-aged children (28). Despite these limitations, this study presents
370
several strengths. This is, to our knowledge, the first study that evaluated the impact of
371
early life nutrition on dietary habits during childhood among children exposed to GDM in
372
utero, a population at high-risk of many health problems such as obesity (1). Another
373
strength is the use of two 24HDR to evaluate current dietary intakes of children. This
374
allowed us to have quantitative data regarding food group intakes, while others studies
375
generally use semi-quantitative questionnaires (10, 11). The use of two recalls, as it has
376
been done by others in large population studies (29-31), helps to reduce the day-to-day
377
variability of dietary intakes measured with 24HDR while minimizing the burden on

379
dietitian minimized risk of food misclassification, especially for fruit juice and fruit
380
drinks.
381
Conclusion
382
This study suggests that early introduction of fruit juice in the infant diet is associated
383
with higher prevalence of consumption of high amounts of fruit juice in GDM+ children.
384
Further studies using a prospective study design in a larger cohort will be necessary to
385
investigated whether delaying or avoiding the introduction of fruit juice in infancy could
386
be a promising strategy to improve dietary habits, with possible lower consumption of
387
high caloric foods, and therefore, prevent obesity among this high-risk population of
388
children.
