Home and Family Environment Related to Development of Obesity: A 21-Year Longitudinal Study.

ABSTRACT: BACKGROUND:Early-life conditions are important for the development of obesity. We hypothesized that home and family characteristics reflective of less supportive environments during childhood will be associated with higher adult BMI and faster BMI growth between ages 5 and 21 years. We also examined the timing and acceleration of BMI increase by adult weight status (normal weight, overweight, obese, and extremely obese) to discern how BMI increase differs across group and across time. METHODS:BMI was assessed in 1000 Chilean youth (52% female) at ages 5, 10, 15, and 21 years. Latent growth curve analysis modeled BMI trajectories from 5 to 21 years. Observer and maternal ratings assessed children's home and family environments and parenting at 1 and 10 years. RESULTS:The four weight groups differed in acceleration of BMI increase starting at age 5, with bigger children getting bigger faster. Higher 21-year BMI related to family stress, father absence, maternal depression, frequent child confinement (in playpen), an unclean home environment at 1 year, and low provision for active stimulation and few stimulating experiences at 10 years. Accelerated BMI increase related to lower learning stimulation in the home at 1 year and less parental warmth and acceptance at child age 10. CONCLUSIONS:Home and family characteristics that reflect an absence of support for children's development were associated with overweight/obesity in young adulthood and accelerated BMI growth. Findings identify several home and family characteristics that can serve as preventive or intervention targets.

Project description:BACKGROUND:Research has demonstrated a significant positive association between frequent family meals and children's dietary intake; however, the promotion of healthful family meals has not been rigorously tested for key food environment and nutrition-related behavioral outcomes in a randomized trial. OBJECTIVE:To describe family home food environment and nutrition-related parent and child personal and behavioral outcomes of the Healthy Home Offerings via the Mealtime Environment Plus program, the first rigorously tested family meals intervention targeting childhood obesity prevention. DESIGN:Randomized controlled trial. Baseline, postintervention (12 months, 93% retention), and follow-up (21 months, 89% retention) data (surveys and dietary recalls) were collected. PARTICIPANTS/SETTING:Children aged 8 to 12 years (N=160) and their parents were randomized to intervention (n=81) or control (n=79) groups. INTERVENTION:The intervention included five parent goal-setting calls and 10 monthly sessions delivered to families in community settings that focused on experiential nutrition activities and education, meal planning, cooking skill development, and reducing screen time. MAIN OUTCOME MEASURES:Family home food environment outcomes and nutrition-related child and parent personal and behavioral outcomes. STATISTICAL ANALYSES PERFORMED:Analyses used generalized linear mixed models. Primary comparisons were contrasts between intervention and control groups at postintervention and follow-up, with adjustments for child age and parent education. RESULTS:Compared with control parents, intervention parents showed greater improvement over time in scores of self-efficacy for identifying appropriate portion sizes, with significant differences in adjusted means at both post-intervention (P=0.002) and follow-up (P=0.01). Intervention children were less likely to consume at least one sugar-sweetened beverage daily at post-intervention than control children (P=0.04). CONCLUSIONS:The Healthy Home Offerings via the Mealtime Environment Plus program involved the entire family and targeted personal, behavioral, and environment factors important for healthful changes in the home food environment and children's dietary intake. The intervention improved two nutrition-related behaviors and this may inform the design of future family meal interventions.
