Institute for Child Health Research, West Perth, WA, Australia 2 School of Psychology, The University of Western Australia, Perth, WA, Australia 3 Department of Endocrinology and Diabetes, Princess Margaret Hospital for Children, Perth, WA, Australia Background: Current treatment programs for childhood obesity have highlighted the importance of the role of the family in treatment. Considering this, it is surprising that few studies have examined the role of family or parental factors in development of childhood obesity. Aim: To examine what family and maternal factors predict higher weight in boys and girls during middle to late childhood. Methods: Longitudinal data from the Childhood Growth and Development Study were used for this research. The study involved 286 healthy weight, overweight and obese children, aged between 6 and 13 years at baseline, who completed baseline, 1year follow-up and 2-year follow-up assessments. Overweight/obese children were recruited from clinical and community settings. The study assessed maternal BMI, maternal education, family structure, family income, maternal psychopathology, maternal self-esteem, parenting style, general family functioning, and negative life events. Linear mixed models were used to identify which of these maternal and family factors predicted child BMI z-score. Results: For community-based children, maternal BMI was a significant multivariate predictor of child BMI z-scores, with increases in maternal BMI being associated with concurrent increases in child BMI z-score. Also for the community based sample, children from a single-parent family had higher BMI z-scores than children from two-parent families. For boys only, a significant interaction was found between maternal BMI and family structure. For girls only, maternal BMI, maternal education and family structure were significant predictors of child BMI z-scores. In addition, a significant interaction effect was identified between maternal education and family structure. For the clinical participants,
ANZOS 2013 abstracts low family income was the only significant multivariate predictor of child BMI z-scores. Conclusion: The strong association between child BMI, maternal BMI and family structure confirms the need to find ways of targeting prevention and intervention efforts for childhood obesity at families with overweight parents, particularly single-parent families. http://dx.doi.org/10.1016/j.orcp.2013.12.711 213 The effectiveness of interventions to promote healthy weight gain in infants and young children from socioeconomically disadvantaged and indigenous families: A systematic review Rachel Laws 1,∗ , Karen Campbell 1 , Georgina Russell 2 , Elizabeth Denney-Wilson 2 , David Crawford 1 , Kylie Ball 1 , John Lynch 3 1 Centre
for Physical Activity and Nutrition Research, Deakin University, Melbourne, VIC, Australia 2 Faculty of Health, University of Technology, Sydney, NSW, Australia 3 School of Population Health, University of Adelaide, Adelaide, SA, Australia Background and aims: Early childhood is an important period for establishing behaviours that will affect weight gain and health across the life course. Children from disadvantaged families including those from low socio-economic backgrounds and indigenous families have significantly higher rates of obesity, making early intervention particularly important in these groups. Little is known however, about the most effective intervention approaches in these populations. This study will report the findings of a systematic review of the effectiveness of interventions to promote healthy weight gain in children 0—5 years from socioeconomically disadvantaged and indigenous families. Methods: Searches of major electronic databases were undertaken to identify intervention studies promoting healthy weight gain in children aged 0—5 years from low socio-economic and indigenous families. Articles published in the last 20 years reporting on feeding practices, anthropometric, diet, physical activity or sedentary behaviour outcomes were included. A total of 4144 unique citations were identified and a screening of titles, abstracts resulted in 83 papers to be reviewed
e119 to identify studies meeting the eligibility criteria. Data on included studies are to be extracted by one reviewer and verified by a second reviewer. Internal and external validity will also be assessed using standard quality rating tools. Results: The review will assess overall effectiveness of the interventions using meta-analysis (if possible) and narrative synthesis. The review will also report on the reach of the interventions, the most important intervention targets, the effectiveness of various intervention strategies and delivery modes as well as the generalizability of the studies. Significance: This review will provide important new information about the best bets in obesity prevention interventions for socioeconomically disadvantaged and indigenous families, as well as identifying key gaps in knowledge to guide future research. To be considered for ‘late breaking abstracts’ with results to be updated. http://dx.doi.org/10.1016/j.orcp.2013.12.712 214 Satiety responsiveness in toddlerhood predicts energy intake and weight status at 4 years of age Kimberley M.

Methods: Using an ‘eating in the absence of hunger’ paradigm, energy intake (kJ) from a semi-standardised lunch meal and a standardised selection of snacks were measured. Participants were 37 children (16 male, Median age = 4.4, IQR = 3.7—4.5 years) recruited via an existing longitudinal study (NOURISH RCT). All participants were tested in their own home. Data on maternal characteristics, child eating behaviours (age 2 years) reported by mothers on a validated questionnaire, and measured child height and weight were collected within the NOURISH trial. Correlation and partial correlation analyses were used to examine longitudinal relationships.
