综合干预儿童单纯性肥胖群体:2年效果观察

Comprehensive intervention in children with simple obesity:two year effect observation

目的探讨综合干预儿童单纯性肥胖群体的方法及其效果。方法从淮北市城区选择6所初中学校作为研究现场,该校所有在校学生为研究对象,其中3所学校为干预组(1831人),3所学校为对照组(2431人)。采用世界卫生组织身高标准值为肥胖判断标准。对干预组进行为期2年的群体干预,干预措施包括膳食调整、运动处方、健康教育、行为矫正、耳穴按压等。干预对象为超重儿童极其家长、肥胖儿童及其家长及非肥胖儿童家长。对照组除与干预组同期体检外不施加任何干预措施。结果①经过2年干预,干预组肥胖发生率从9.8%降至6.9%(χ2=9.77,P<0.01),对照组肥胖发生率从9.9%上升为12.3%(χ2=7.09,P<0.01)。干预后两组肥胖发生率差异有显著性意义。②干预后肥胖度干预组从(45.9±11.8)%降至(34.2±11.8)%,结果差异有显著性意义(u=29.8,P<0.001),对照组从(46.2±12.1)%上升至(48.9±13.7)%,结果差异有显著性意义(u=7.27,P<0.001)。干预组与对照组儿童身高增长幅度基本一致。③干预后血总胆固醇、三酰甘油、载脂蛋白B及收缩压降低,而对照组肥胖儿童无明显变化。结论儿童单纯性肥胖群体综合干预可有效降低儿童肥胖发生率和肥胖度及心脑血管疾病的危险因素。

AIM:To explore the method and effect of comprehensive intervention on simple obesity of children. METHODS:Six junior middle schools were selected as investigation sites,and students in these schools were chosen as subjects.Three of the schools consisted of intervention group(1 831 cases) and the other three were as control group (2 431 cases).WHO height norm value was used to measure the obesity.The intervention group received two year colony intervention,including dietary adjustment,sport prescription,health education,behavior modification,stimulate acupuncture at ear.The intervention subjects were excess child, obese child,no obese child and their parents.Except for physical examination, the control group was not inflicted on any other factor. RESULTS:①The incidence of obesity among the students in the intervention group was reduced from 9.8%to 6.9%(χ2=9.77,P< 0.01),while that of the control group was increased from 9.9%to 12.3%(χ2=7.09,P< 0.01) over the 2 year intervention period.After the intervention,the incidence of the two groups showed significant differences.②The degree of obesity among the students in the intervention group was reduced from (45.9±11.8)%to(34.2±11.8)%and the differences were significant(u=29.8, P< 0.001), that of the control group was increased from(46.2±12.1)%to (48.9±13.7)%and the differences was significant (u=7.27, P< 0.001).Increment of height of students was almost same in the intervention group and control group.③Blood total cholesterol,triglyceride, apolipoprotein B and systolic pressure all dropped after intervention,and there was no significant change in the students of the control group. CONCLUSION:The comprehensive intervention of simple obesity for children can effectively reduce the prevalence of obesity,obesity degree and risk factor of cardiovascular disease.
