| Outline of Final Research Achievements |
This study examined characteristics and determinants of toddlers' objectively measured physical activity and obesity. The results showed that toddlers engaged in 468 min/day (67%/day) of sedentary behavior, 65 min/day (9%/day) of moderate-to-vigorous physical activity, and 6399 step counts/day. Unlike preschoolers after 3 years of age, there were no significant gender differences on toddlers' physical activity, and weekend physical activity was higher than weekdays. Toddlers' sedentary time was related to their mothers' sedentary time on weekdays and their fathers' outdoor play time with their child on weekends. Moreover, encouraging their children to be active, and fathers' BMI, but not mothers' correlated with their children's obesity index.
