目的:了解成都市3~6岁学龄前儿童超重、单纯性肥胖发展趋势和干预效果,以寻求更有效的干预措施。方法:自2000~2007年对成都市五城区所有一类托幼园所3~6岁儿童进行调查,对其超重、肥胖发生、发展动态趋势进行分析研究,并设重点干预点进行连续干预监测。参照WHO标准,应用身高别体重法评价儿童超重和肥胖。结果:2000~2005年中,成都市学龄前儿童超重、单纯性肥胖发生率显著升高(2000年为6.50%、2.14%;2005年为9.57%,4.39%,P<0.001);通过对托幼园所实施肥胖干预后,2005~2007年儿童超重、单纯性肥胖检出率处于稳定控制状态(2007年为9.13%,4.17%,P>0.05)。2005~2007年对本市15所托幼机构实施重点干预后,儿童超重、肥胖检出率为8.51%,3.26%,明显降低(P<0.05),而一般干预点,超重、肥胖发生率明显升高(10.42%,5.12%,P<0.05)。结论:学龄前儿童超重、单纯性肥胖呈上升趋势,有效的干预措施能控制超重和肥胖发生率。
Objective: To understand the development trend and intervention effect of overweight and simple obesity in preschool children aged 3 ~ 6 in Chengdu in order to seek more effective interventions. Methods: From 2000 to 2007, children aged 3 ~ 6 years old in kindergartens of all five districts in Chengdu City were investigated. The occurrence and development trends of overweight and obesity were analyzed and analyzed. Continuous intervention monitoring was conducted with key intervention points . According to WHO standards, height and weight were used to evaluate children’s overweight and obesity. Results: From 2000 to 2005, the incidence of overweight and simple obesity among preschool children in Chengdu was significantly higher (6.5%, 2.14% in 2000; 9.57%, 4.39%, P <0.001 in 2005) After implementation of obesity intervention in kindergarten, the detection rate of overweight and simple obesity in children from 2005 to 2007 was in a steady state of control (9.13% and 4.17% in 2007, P> 0.05). From 2005 to 2007, the detection rate of children overweight and obesity was 8.51% and 3.26%, respectively, significantly reduced (P <0.05) after intervention in 15 nurseries in the city. However, the incidence of overweight and obesity was significantly increased High (10.42%, 5.12%, P <0.05). CONCLUSION: Overweight and simple obesity in preschool children is on the rise. Effective interventions can control the incidence of overweight and obesity.
