Familial Factors Associating with Youth Physical Activity Using a National Sample

The purpose of this study was to examine the associations of familial and child-related factors with reported child physical activity using a representative sample of US children and adolescents. Data were analyzed from the combined 2017–2018 National Survey of Children’s Health. Household addresses were randomly selected within each US state. One parent within each household answered health and wellness questions pertaining to one randomly selected child (n = 37,392; 48.8% female; 6–17 years old). Weighted logistic regression models examined the independent and joint associations between family-level and child-level factors with a child meeting the 60 min of physical activity per day guideline. After controlling for confounders, higher levels of family resilience (odds ratio (OR) = 2.17; 95% confidence interval (CI): 1.35–3.49, p = 0.001), high event attendance (OR = 1.65; 95%CI: 1.18–2.31, p = 0.004), and high family income (OR = 1.84, 95%CI: 1.34–2.52, p < 0.001) significantly associated with higher odds of a child meeting the 60 min of physical activity per day guideline. Family generational status and adult education significantly modified the association between family resilience and child physical activity. Programs that develop family resilience and encourage parental attendance for their child’s events or activities may positively influence a child’s physical activity behaviors. Expanded or enhanced programming may be needed for lower income families.
