目的比较超重与正常体重儿童体适能、体力活动的差异及其父母与子女体力活动水平之间的关系,为制定针对肥胖儿童的干预方案提供参考。方法选取扬州市某小学119名8岁儿童及其父母为研究对象。采集身高、体重、体质量指数(BMI)数据,使用体力活动问卷测量儿童及其父母的体力活动水平,采用中国体质健康指标中8个运动测试全面评定儿童体适能水平。结果超重男童体力活动水平(2.90±0.65)与正常体重儿童(2.41±0.72)差异均有统计学意义(t=2.89,P<0.05)。母亲与其子女的体力活动水平呈正相关(β男=0.32,β女=0.35,P值均<0.05)。结论超重儿童体适能、体力活动水平低于正常体重儿童,母亲体力活动水平与子女体力活动水平关系密切。
Objective To compare the differences of physical fitness and physical activity between overweight and normal weight children and the level of their parents’ and their children’s physical activity so as to provide a reference for making intervention programs for obese children. Methods A total of 119 8-year-old children and their parents in a primary school in Yangzhou City were selected as the study objects. Body height, weight and body mass index (BMI) data were collected. Physical activity questionnaire was used to measure the physical activity level of children and their parents. 8 physical fitness tests were used to evaluate children’s physical fitness level comprehensively. Results There was a significant difference in the level of physical activity between overweight boys (2.90 ± 0.65) and normal weight children (2.41 ± 0.72) (t = 2.89, P <0.05). Mothers had positive correlation with their children’s physical activity (β = 0.32, β = 0.35, P <0.05). Conclusion The physical fitness and physical activity level of overweight children is lower than that of normal weight children. The physical activity level of mothers is closely related to the physical activity level of their children.
