on behalf of the TARGetKids! Collaboration ABSTRACT OBJECTIVES: To determine whether parent report of difficulty buying food was associated with child body mass index (BMI) z-score or with eating habits in young children.METHODS: This was a cross-sectional study in primary care offices in Toronto, Ontario. Subjects were children aged 1-5 years and their caregivers, recruited through the TARGet Kids! Research Network from July 2008 to August 2011. Regression models were developed to test the association between parent report of difficulty buying food because of cost and the following outcomes: child BMI z-score, parent's report of child's intake of fruit and vegetables, fruit juice and sweetened beverages, and fast food. Confounders included child's age, sex, birth weight, maternal BMI, education, ethnicity, immigration status, and neighbourhood income.
RESULTS:The study sample consisted of 3333 children. Data on difficulty buying food were available for 3099 children, and 431 of these (13.9%) were from households reporting difficulty buying food. There was no association with child BMI z-score (p = 0.86). Children from households reporting difficulty buying food (compared with never having difficulty buying food) had increased odds of consuming three or fewer servings of fruits and vegetables per day (odds ratio [OR]: 1.31, 95% confidence interval [CI]: 1.03-1.69), more than one serving of fruit juice/sweetened beverage per day (OR: 1.60, 95% CI: 1.28-2.00), and, among children 1-2 years old, one or more servings of fast food per week (OR: 2.91, 95% CI: 1.67-5.08).CONCLUSION: Parental report of difficulty buying food is associated with less optimal eating habits in children but not with BMI z-score.KEY WORDS: Child; obesity; diet; poverty; food supply La traduction du résumé se trouve à la fin de l'article.Can 4 The most recent prevalence of food insecurity reported, also using data from the CCHS, was 12.0% in 2014 in participating provinces and territories.
5Household food insecurity has been associated with multiple nutritional risk factors that may be associated with obesity in toddlers, including lower fruit and vegetable intake 6,7 and higher sugar-sweetened beverage intake, 7 as well as lower levels of physical activity and higher screen time in young children. 8 Poverty hasshown similar associations with nutritional risk. 9 Recent studies have also indicated that food insecurity may lead to obesogenic feeding behaviours, such as restriction of food and pressure to eat, in infants. 10 However, studies examining food insecurity as a predictor of obesity in young children have shown conflicting results.
11While some studies have examined food insecurity in the US using national-level data, research specific to the Canadian population is important, as mechanisms of public income and We thank Deborah Frank for her thoughtful feedback on our manuscript.
