目的探讨社会生态模式对学生进行肥胖干预对体脂含量的有效性,为制定科学有效的青少年肥胖干预措施提供依据。方法利用分层整群抽样方法,选择北京市房山区城市、乡村小学、中学各4所共16所学校7~18岁学生共3 164名,平均年龄(11.31±2.19)岁,其中各选取2所学校共1 656名进入干预组。利用社会生态理论模型从学生、学校、家庭3个层面进行为期3个月的肥胖干预。干预方式包括健康教育、改善环境等,干预内容包括健康饮食与运动等。干预前后分别测量体脂含量。结果干预组体脂含量上升了1.69百分点,对照组上升了2.52百分点,对照组的上升幅度高于干预组(t=2.91,P=0.004)。干预效果女生(干预组上升1.24百分点,对照组上升2.58百分点,P=0.005)优于男生(干预组上升2.12百分点,对照组上升2.47百分点,P=0.287),小学生(干预组上升1.16百分点,对照组上升3.14百分点,P<0.01)优于中学生(干预组上升2.29百分点,对照组上升2.00百分点,P=0.128),乡村学生(干预组上升2.08百分点,对照组上升2.69百分点,P=0.006)优于城市学生(干预组上升1.31百分点,对照组上升2.33百分点,P=0.054),对非超重肥胖学生、超重肥胖学生均有效。结论社会生态模型可以有效控制儿童青少年的体脂含量,从而有效防控肥胖。在以后的干预中可以考虑进行学生、学校、家庭多个层面的干预措施。
Objective To explore the effectiveness of social ecological model on body fat content of obesity intervention in students and to provide a basis for the establishment of a scientific and effective intervention for obesity in adolescents. Methods By stratified cluster sampling, 3 164 students aged 7-18 years from 16 schools in 4 primary and secondary schools in Fangshan District of Beijing were enrolled, with an average age of (11.31 ± 2.19) years, of which 2 A total of 1 656 schools entered the intervention group. Using the theory model of social ecology from three levels of students, schools, families for a period of 3 months of obesity intervention. Interventions include health education, improvement of the environment, interventions include healthy diet and exercise. Before and after intervention were measured body fat content. Results The body fat content of the intervention group increased by 1.69 percentage points, while that of the control group increased by 2.52 percentage points. The increase of the control group was higher than that of the intervention group (t = 2.91, P = 0.004). The effect of intervention was 1.24 percentage points higher in the intervention group and 2.58 percentage points higher in the control group (P = 0.005) than in the boys (2.12 percentage points in the intervention group and 2.47 percentage points in the control group, P = 0.287) and 1.16 percentage points in the intervention group (P <0.01) was better than that of middle school students (the intervention group increased 2.29 percentage points and the control group increased 2.00 percentage points, P = 0.128); the rural students (intervention group increased 2.08 percentage points and the control group increased 2.69 percentage points, P = 0.006) In city students (the intervention group increased by 1.31 percentage points and the control group increased by 2.33 percentage points, P = 0.054), it was effective for non-overweight obese students and overweight obese students. Conclusion The social ecological model can effectively control the body fat content of children and adolescents, thus effectively preventing and treating obesity. In future interventions, interventions at multiple levels of students, schools and families may be considered.
