目的 探讨学龄前集体管理儿童的肥胖干预方法,为从公共卫生角度早期控制、减少肥胖发生率提供科学依据。方法 自2009年7月起,随机选取干预和对照幼儿园各2所,对在园3~4岁儿童进行为期2年的监测。对干预幼儿园进行健康教育宣传,比较干预前后儿童的膳食频率和肥胖发生率。结果 干预后儿童的饮食行为较对照组幼儿园有明显改善,差异有统计学意义(P<0.05)。干预后肥胖发生率有所降低,但与对照组比较差异无统计学意义(P>0.05)。 结论 在幼儿园学龄前进行健康教育预防肥胖的发生是可行的。但对于肥胖儿童需要更有利的干预措施才能控制和减少肥胖。

Objective To study the obesity intervention methods of preschool children in collective management and to provide the scientific basis for public health and early control,reduce the incidence of obesity.

Results After the intervention,the children's eating behavior of the control group kindergarten had obviously improved and there were significant differences(P<0.05).After intervention obesity rates had fallen,but compared with no significant differences(P>0.05). Conclusions Health education in preschool kindergarten to prevent obesity happened is feasible.But more favorable intervention measures are needed to reduce the occurrence of obesity for obese children.
