Youth and caregiver physical activity and sedentary time: HCHS/SOL Youth

Objectives: We examined associations between youth and caregiver moderate/ vigorous physical activity (MVPA) and sedentary (SED) time, using accelerometery, in the Hispanic Community Health Study/Study of Latino Youth (HCHS/ SOL) Youth. Methods: Participants were 623 caregivers and 877 youth 8-16 years old, enrolled in 2012-2014. Associations of youth and caregiver MVPA time, SED time, and meeting MVPA recommendations (> 150 min/week, adults; > 420 min/week, youth) were examined in regression models that controlled for sample weights, design effects, and demographic and health covariates. Results: Youth whose caregivers met MVPA recommendations were nearly twice as likely to meet these recommendations themselves when compared to youth whose caregivers did not meet MVPA recommendations (OR = 1.9, 95% CI 1.1, 3.3). Youth and caregiver SED time also were significantly related (p < .05). A similar pattern of findings was observed in analyses limited to relationships in which the caregiver was a biological parent of the youth (N = 485 caregivers; N = 795 youth). Conclusions: MVPA and SED are correlated within Latino families as observed by statistically significant relationships of youth and caregiver activity. Additional research is needed to understand underlying genetic and environmental factors that explain these findings.
