Low-Income Latina Mothers' Scaffolding of Preschoolers' Behavior in a Stressful Situation and Children's Self-Regulation: A Longitudinal Study.

Objective: Maternal control and directiveness in Latina/o families often do not show the negative associations with child adjustment seen in European American samples. This study tested the self-determination hypotheses that Latina maternal involvement and structure would be positively associated with preschool children's later self-regulation, whereas directiveness and control would show negative relations. Design: At Time 1, 130 low-income Latina mothers were observed helping their 4- to 5-year-old children complete a stressful task. Maternal strategies for scaffolding children's responses to stress were examined with detailed event coding. At Time 1 and Time 2 18 months later, a delay of gratification task assessed children's self-regulation. Results: Children's Time 2 ability to delay gratification at 5½ to 6½ years (controlling for delay of gratification at ages 4 to 5) was predicted by Time 1 maternal scaffolding strategies. Children showing the greatest delay gratification at Time 2 (controlling for delay of gratification at Time 1) had mothers who used instructive praise and nonverbal autonomy-promoting scaffolding strategies at Time 1. Negative predictors included nonverbal attention directing and restriction. Conclusions: The findings highlight the importance of physical guidance in Latina/o families and suggest that highly directive maternal strategies may not interfere with the development of self-regulation as is often found in European American families. These findings will be useful in developing interventions to promote self-regulation in Latina/o children from low-income families.

Twelve-Month Efficacy of an Obesity Prevention Program Targeting Hispanic Families With Preschoolers From Low-Income Backgrounds.

OBJECTIVE: Assess effects of an obesity prevention program promoting eating self-regulation and healthy preferences in Hispanic preschool children. DESIGN: Randomized controlled trial with pretest, posttest, 6- and 12-month assessments. Fourteen waves, each lasting 7 weeks. SETTING: Families recruited from Head Start across 2 sites. PARTICIPANTS: Two hundred fifty-five families randomized into prevention (n = 136) or control (n = 119). INTERVENTION: Prevention received curriculum; control received no curriculum. MAIN OUTCOME MEASURE(S): Feeding knowledge/practices/styles (parent); body mass index percentile, eating self-regulation, trying new foods, and fruit/vegetable consumption (child). ANALYSIS: Multilevel analyses for nested data (time points within families; families within waves) and multinomial regression. RESULTS: Program increased mothers' repeated presentation of new foods (P < 0.05), measured portion sizes (P < 0.05), child involvement in food preparation (P < 0.001), feeding responsiveness (P < 0.001), knowledge of best feeding practices (P < 0.001), and feeding efficacy (P < 0.05); reduced feeding misconceptions (P < 0.01) and uninvolved feeding (P < 0.01). Effects on child eating behavior were minimal. At 12 months, children in the prevention group were less likely to have overweight (P < 0.05) or obesity (P < 0.05). CONCLUSIONS AND IMPLICATIONS: Program effects emphasize the importance of feeding approaches in reducing childhood obesity.

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.
