摘要
【目的】 探索儿童单纯肥胖症的群体干预方法 ,降低学龄儿童肥胖发病率。 【方法】 从北京市城区选择 5所小学作为研究现场 ,该小学所有学生均为研究对象 ,其中 2所学校为干预组 (15 97人 ) ,3所学校为对照组 (2 118人 )。采用WHO身高标准体重值为肥胖判断标准。对干预组进行为期 3年的群体干预 ,干预措施包括健康教育、增加运动和饮食调整 ,重点为调整晚餐进食顺序、增加蔬菜水果的摄入量、减少静坐时间、增加运动等。干预对象为超重儿童及其家长、肥胖儿童及其家长、非肥胖儿童家长。对照组除与干预组同期体检外不接受任何干预措施。 【结果】 经过3年干预 ,干预组肥胖发病率从 16.9%降至 12 .1% (P <0 .0 1) ,对照组肥胖发病率从 17.4%上升为 2 3 .2 % (P <0 .0 1)。干预后两组肥胖发病率差别极显著。对干预组 75 7名 1~ 3年级儿童进行追踪观察 ,3年后原非肥胖儿童中 3 .6%成为肥胖儿童 ,原肥胖儿童中 5 9.1%仍维持肥胖状态。对照组 10 3 1名 1~ 3年级儿童中 ,有 11.9%的原非肥胖儿童三年后为肥胖儿童 ,原肥胖儿童中 92 .2 %仍维持肥胖状态。干预组非肥胖儿童成为肥胖的危险性明显小于对照组 ,对照组肥胖儿童维持肥胖的可能性明显大于干预组。
To evaluate the impact of a school-based intervention program to childhood obesity and to reduce the prevalence of obesity among school childrenTwo intervention and three control primary schools were selected from Beijing urban district,randomly,to attend the field trial. all the children (3 715 students, grade 1 to 6)from these 5 schools were involved the study and there were 1 597 in intervention schools(interventiong group) and 2 118 in control schools (control group), respectively. The children from 2 intervention schools participated in a school-based intervention program over 3 school years (from 1997 to 2000).The program included health education, exercise,and dietary adjustment. The progam focused on decreasing consumption of high-caloric foods and incerasing fruit and vegetable intake in supper, and decreasing sedentary time. Obesity was defined by WHO standard weight for height. Outcomes were assessed using pre-intervention and follow-up measures.The prevalence of obesity among the children in intervention group was reduced from 16.9% to 12.1% over the 3 school years intervention periods. The obesity prevalence among the children in control group increased from 17.4% to 23.2% over the 3 school years. The prevalence of obesity in intervention group was significantly lower than control group after intervention. Among the children in intrevention group,3.6% of no-obese children became to obese and 59.1% of obese children remained obese over the 3 school years intervention periods. During the same 3 years, 11.9% of no-obese children became to obese and 92.2% of obese children remained obese among the children in control group. The obesity incidence was significantly less for the children who were no-obese in intervention than control group(odds ratio,0.276,95% confidence interval, 0.127~0.443,P<0.01). The percent of obesity maintenance was significantly greater for the children who were obese in control vs intervention group(OR,0.122,95% CI,0.062~0.240,P<0.01).[Conclusion]The school-based intervention program was suitable and effective in school, and reduced prevalence of obesity significantly among school children.
