Short-Term Effects of an Obesity Prevention Program Among Low-Income Hispanic Families With Preschoolers.

OBJECTIVE: To assess the short-term effects of an obesity prevention program promoting eating self-regulation and healthy food preferences in low-income Hispanic children. DESIGN: Randomized controlled trial with pretest, posttest, and 6- and 12-month assessments. SETTING AND PARTICIPANTS: Head Start and similar early learning institutions in Houston, TX, and Pasco, WA. A total of 255 families with preschoolers randomized into prevention (n = 136) and control (n = 119) groups. INTERVENTION: Multicomponent family-based prevention program. Fourteen waves lasted 7 weeks each with 8-10 mother-child dyads in each group. MAIN OUTCOME MEASURES: Parent assessments included feeding practices, styles, and knowledge. Child assessments included child eating self-regulation, willingness to try new foods, and parent report of child fruit and vegetable preferences. Parent and child heights and weights were measured. ANALYSIS: Multilevel analyses were employed to consider the nested nature of the data: time points within families within waves. RESULTS: The program had predicted effects on parental feeding practices, styles, and knowledge in the pre- to post-comparisons. Effects on child eating behavior were minimal; only the number of different vegetables tried showed significant pre-post differences. CONCLUSIONS AND IMPLICATIONS: Short-term effects of this prevention program highlight the importance of family-focused feeding approaches to combating child overweight and obesity.

Emotion regulation strategies and childhood obesity in high risk preschoolers.

The current study examined the relationships between the specific strategies that preschool children use to regulate their emotions and childhood weight status to see if emotion regulation strategies would predict childhood weight status over and above measures of eating self-regulation. 185 4- to 5-year-old Latino children were recruited through Head Start centers in a large city in the southeastern U.S. Children completed both a delay of gratification task (emotion regulation) and an eating in the absence of hunger task (eating regulation). Eating regulation also was assessed by maternal reports. Four emotion regulation strategies were examined in the delay of gratification task: shut out stimuli, prevent movement, distraction, and attention to reward. Hierarchical linear regressions predicting children's weight status showed that both measures of eating regulation negatively predicted child obesity, and the use of prevent movement negatively predicted child obesity. Total wait time during the delay of gratification tasks was not a significant predictor. The current findings are consistent with studies showing that for preschool children, summary measures of emotion regulation (e.g., wait time) are not concurrently associated with child obesity. In contrast, the use of emotion regulation strategies was a significant predictor of lower child weight status. These findings help identify emotion regulation strategies that prevention programs can target for helping children regulate their emotions and decrease their obesity risk.
