Parents' participation in physical activity predicts maintenance of some,but not all, types of physical activity in offspring during early adolescence:A prospective longitudinal study

摘要

Purpose: We aimed to examine the longitudinal associations between parents' and youth's participation in physical activity(PA).Methods-: One hundred and ninety youth cuompleted self-admitiistered questionnaires 3 times per year from 2011 to 2015, and their parents completed an interviewer-administered questionnaire during a telephone interview once in2011-2012. Data on youth's and parents' activities were classified as interdependent or coactive/imdependent.Results: Youth with one or both parents who participated in interdependent activities were more likely to maintain participation in interdependent activities(hazard ratio(HR) = 3.63: 95% confidence interval(CI) = 1.30-10.17). Youth's sustained participation in coactive/independent activities was not associated with parents' participation in coactive/independent activities(HR= 0.97; 95%CI=0.46-2.06).Conclusion: Longitudinal associations between parents' and youth's participation in PA differed across type of PA. Encouraging parents' participation in interdependent activities may promote sustained participation in interdependent activities in youth.
