A recent study published in Childhood Obesity by DUPRI Scholars Michelle White and James Moody, DUPRI student Madelynn Wellons, and their co-authors explores how the characteristics of parents’ social networks may influence obesity and health behaviors in young children. The research focuses on African American and Hispanic families, two groups at elevated risk for childhood obesity, and investigates how the social connections of parents may play a role in shaping their children’s health outcomes.
The study analyzed data from 118 parents—74 African American and 44 Hispanic—of children aged 2 to 4 years, using a cross-sectional, observational design. Researchers adapted the social network survey from the Important and Health Matters Social Network Battery (PhenX Toolkit) and assessed child health behaviors using items from the National Health and Nutrition Examination Survey. Children’s body mass index z-scores (BMIz) were calculated from measured height and weight recorded at their most recent well-child visit. Linear regression models were employed to assess associations between parent network characteristics, child BMIz, and specific health behaviors.
Findings revealed that parents of Hispanic children reported fewer supportive social connections than African American parents, naming an average of 3.7 versus 5.0 supportive individuals in their networks, a difference that approached statistical significance. Across both groups, a higher number of stressful relationships within a parent’s network was significantly associated with a higher child BMIz. Among African American families, a greater number of supportive network members was linked to longer weekday and weekend sleep for children, and reduced weekday screen time. In Hispanic families, having more individuals with whom the parent discussed important matters was associated with increased child sleep during the week.
These findings underscore the importance of parent social networks in influencing early childhood health behaviors and weight outcomes, with notable variations by population. Strengthening supportive relationships and reducing parental stress within these networks may be promising strategies for addressing obesity risk in young children.
