Parent–child associations for changes in diet screen time and physical activity across two decades in modernizing China: China Health and Nutrition Survey 1991–2009

摘要

BackgroundWhile the household context is important for lifestyle behavior interventions, few studies have examined parent–child associations for diet and physical activity (PA) changes over time in a rapidly urbanizing country. We aimed to investigate changes in diet, screen time, and PA behaviors over time in children and their parents living in the same household, and examine the parent–child association for these behaviors.
