AIM: This study examined the pattern of sedentary behaviour during the week and on weekends, and associations with health outcomes among children aged 5-7 years in Sweden.
METHODS: This cross-sectional study used data from 342 children, many of whom had at least one parent born outside the Nordic region. Physical activity and sedentary time were measured by accelerometry. A sedentary bout was defined as 1-4 and 5-9 minutes. Diet, time in front of television or computer screen, sleep and physical activity behaviour were measured via parental reports, and anthropometric data by research staff.
RESULTS: The number of sedentary bouts was higher on weekends than on weekdays. Compared to girls, boys had more 1-4 minute bouts on both weekdays and weekend days, and more 5-9 minute bouts on weekends. A higher number of 5-9 minute bouts was associated with a higher body mass index and waist circumference.
CONCLUSION: This study showed an association between sedentary activity and weight status in children as young as 5-7 years. Reducing time, especially longer bouts, spent in sedentary activities may encourage healthy weight development in children.
