Abstract
This study aimed to collect survey data on physical activity and organized sport participation among children across different weight categories. Using online data collection, 906 parents provided information about 1002 children (age = 10.9 ± 2.5 years, body height = 150.2 ± 16.4 cm, and body mass = 42.4 ± 15.8 kg). Most children (79%) achieved the recommended 60 min. of moderate-to-vigorous physical activity (MVPA) per day; 50% participated in club sports; and 41% took part in organized sports. Most of them (69%) were in the healthy weight category, 7% were underweight, and 22% of the children were overweight or obese. Participation in sports activities among overweight and obese children was nearly as high as among their peers. Achieving 60 min. of MVPA/day was associated with significantly lower odds (OR = 0.51 CI: 0.30-0.85; p < 0.01) of childhood obesity in the total sample. Football was the most popular club and organized sport among boys, while dancing was most preferred among girls. The preferred sports were generally well-suited to the respective weight categories. The relatively high levels of physical activity observed may be explained by daily physical education (PE) classes in schools and governmental support for sports. Our findings suggest that further research is needed to support effective obesity prevention, particularly those examining dietary habits and other lifestyle factors.
