| Summary: | 碩士 === 臺北醫學大學 === 護理學研究所 === 96 === Overweight, obese children and adolescents are increasing worldwide. This health problem has been considered in relation to genetic, environmental and social-cultural factors. Due to changes of activity patterns in recent years, children’s physical activity decrease and sedentary activity increase. Besides that children engage in different sedentary activities from before. Hence, research need to investigate the relationships between sedentary behavior and overweight (include obese); however research results have been inconsistent findings, for that further research. The aims of this study are understand children’s sedentary activity patterns and compare their sedentary activities after school between the overweight (include obese) and normal weight school-age children.
The design of this study is case control Purposive sampling was used to select 196 fourth-grade overweight (include obese) children with their parents, and 196 class, age, and gender- matched control. Three-day physical activity record was used three consecutive days to obtain sedentary activities and in order to compare sedentary activities between the overweight and normal weight school-age children.
The results of this study were as below: The sample consists of 238 boys and 190 girls that have a mean age of 9.8 year. (1) Children spent time on sedentary activity 273.2min. Children spent more time on homework, cram school and TV viewing on weekday. However, children spent more time on TV viewing and doing homework on weekend. (2) Total and central overweight(include obese) children spent more time on television viewing significant more than normal weigh children (p <.01) and central obesity children spent more time on reading significant less than normal weight children (14.6min/day vs. 22.2min/day, p <.01) on weekday. Time spent on TV viewing(p <.05) and total media time (p <.01)more than 2 hours are related to central obesity for self-report nonacademic sedentary activity, and which are related to total and central obesity for parent-report.
The results of the research can be used for the improvement of education and school units. Suggestions are made to develop interventions to reduce the time in sedentary activities, and increase physical activity levels in order to prevent children’s overweight and obese.
