Parental physical activity (PA) and reduced sedentary time are linked to increased child PA. However, excessive parental moderate-to-vigorous PA may inversely affect children's activity levels, warranting further investigation.
Area of Science:
- Pediatric obesity prevention
- Public health research
- Behavioral science
Background:
- Low-income children in the U.S. face higher obesity rates.
- Limited research exists on parental physical activity (PA) and sedentary behavior modeling in low-income ethnic minority families.
- Objective measures of preschooler and parent PA are scarce.
Purpose of the Study:
- To examine the association between parent and child physical activity (PA) and sedentary behaviors.
- To investigate parental modeling effects on children's PA in a low-income, multiethnic population.
Main Methods:
- Cross-sectional study of 1,003 low-income parent-child pairs (Latino and African American).
- Objective PA measurement using accelerometers worn by parents and children for 7 days.
- Analysis of sedentary behavior, light PA, and moderate-to-vigorous PA (MVPA) associations.
Main Results:
- A positive association was found between parent and child sedentary behavior and light PA.
- Child and parent MVPA showed a positive correlation up to 40 minutes of parental MVPA daily.
- An inverse association between parent and child MVPA emerged when parental MVPA exceeded 40 minutes per day.
Conclusions:
- Increased parental PA and decreased sedentary behavior correlate with enhanced child PA.
- Further research is necessary to elucidate the effects of high parental MVPA on children's MVPA levels.
