Is overweight at 12 months associated with differences in eating behaviour or dietary intake among children selected for inappropriate bottle use?

Bottle feeding beyond the recommended weaning age of 12 months is a risk factor for childhood obesity. This paper describes a sample of toddlers at high risk for obesity: prolonged bottle users from a low-income multi-ethnic community. We report here baseline mealtime and feeding behaviour, 24h dietary recall and bottle intake data for Feeding Young Children Study (FYCS) participants, by overweight (≥85% weight-for-length) status. FYCS enrolled 12-13-month-olds from urban nutrition programmes for low-income families in the United States who were consuming ≥2 bottles per day. Our sample was predominately Hispanic (62%), 44% of mothers were born outside of the United States and 48% were male. Overall, 35% were overweight. Overweight status was not associated with mealtime/feeding behaviours, bottle use or dietary intake. Most (90%) children ate enough, were easily satisfied and did not exhibit negative (e.g. crying, screaming) mealtime behaviours, per parent report. The sample's median consumption of 4 bottles per day accounted for 50% of their total calories; each bottle averaged 7 ounces and contained 120 calories. Mean daily energy intake, 1098.3kcal day^-1 (standard deviation=346.1), did not differ by weight status, nor did intake of fat, saturated fat, protein or carbohydrates. Whole milk intake, primarily consumed via bottles, did not differ by weight status. Thus, overweight 12-13-month-olds in FYCS were remarkably similar to their non-overweight peers in terms of several obesity risk factors. Findings lend support to the set-point theory and prior work finding that weight and intake patterns in the first year of life alter subsequent obesity risk.
