Sociodemographic differences in patterns of sedentary and physically active behavior in older children and adolescents
ABSTRACT Numerous studies have found that involvement in moderate-intensity and strenuous activity has positive effects on health. This study considered the prevalence of different aspects of physical activity and sedentary behavior in 11-16-y-olds based on a representative national survey of 3270 Icelandic primary schoolchildren (91% response rate). All-day sedentary behavior was extremely rare (< 1%), and the vast majority (91%) were physically active (> or = 3 times per week) during school or leisure time, thanks largely to school physical education. Only 39% were physically active (> or = 3 times per week) during leisure time, and only 29% engaged in regular (> or = 3 times per week) leisure time strenuous exercise. Girls were more sedentary, less leisure time physically active, and less involved in leisure time strenuous exercise. Sedentary behavior increased and physically active behavior decreased with age, especially after early adolescence. However, there were no age differences in strenuous leisure time exercise. Upper-class students were less sedentary and more physically active during leisure time than working-class students. Finally, rural students were more sedentary during leisure time, and less physically active than students from urban areas. An interaction was found between age and residence when predicting leisure time physical activity, indicating that the inverse age-activity relationship in urban areas is partly reversed in rural areas. Conclusion: Compulsory school physical education frequently failed to translate into voluntary physical involvement. Sociodemographic differences in physical activity were greater during leisure time, than during school and leisure time combined.

ABSTRACT: The purpose of this cross sectional study was to explore the physical activity patterns of a group of rural children living in Saskatchewan, Canada. Of the 103 participants (aged 8-13 years), 53.7% met the national guideline for the amount of physical activity required to achieve optimal health benefits. Children's involvement in out of school organized physical activities, (e.g. baseball, soccer, dance) was associated with whether or not they met the guideline. There was no statistically significant association between the children's physical activity and their participation in physical activities in school, television watching behavior, or their parents' educational levels. Results suggest that many rural children in Saskatchewan are not physically active enough for health benefits and several factors can potentially influence the physical activity of this group of children. Further exploration of such factors may assist families, communities, schools, and health professionals in promoting physical activity in this population.
