摘要

摘要: 目的探讨儿童肥胖综合干预对自我效能、体重认知和行为改变阶段的作用, 为儿童肥胖的干预提供科学依据。方法研究设计为整群随机对照人群试验。2013年9月在北京市东城区选取12所小学的1 889名儿童(7~11岁), 开展肥胖综合干预。6所学校(930名)被随机分配至干预组, 6所学校(959名)被随机分配至对照组, 干预时长为1年。对研究对象开展面对面问卷调查, 使用R 4.0.3软件分析数据, 并采用多元线性回归模型分析干预效果。结果干预后, 干预组与对照组儿童自我效能评分分别为(4.4±0.9)和(4.2±1.1)分。干预后, 干预组低估和高估自我体重的比例分别为28.4%和11.3%, 对照组则为37.1%和6.9%;相比对照组, 干预组儿童低估体重的风险降低(OR=0.64, 95%CI=0.52~0.80, P<0.01), 高估体重的风险增加(OR=1.79, 95%CI=1.26~2.54, P<0.01)。干预后, 干预组儿童处于行为改变意向阶段和行动阶段的比例分别为65.3%和83.6%, 对照组则为59.8%和69.8%;相比于对照组, 干预组更多儿童在行为改变中转变为意向阶段(OR=1.28, 95%CI=1.03~1.59, P=0.02)和行动阶段(OR=2.59, 95%CI=2.04~3.27, P<0.01)。结论儿童肥胖综合干预对提高自我效能、改善体重认知和促进行为改变有积极作用, 但会增加高估体重的风险。

Abstract: Objective To evaluate the effectiveness of a comprehensive intervention for childhood obesity on self-efficacy, weight perception, and stage of behavior change, and to provide a scientific evidence for childhood obesity interventions. Methods The study was a cluster-randomized controlled trial. Twelve primary schools and 1 889 children (aged 7-11 years) from Dongcheng District in Beijing were recruited in September, 2013, and were administered a comprehensive intervention for childhood obesity. Six schools (930) were randomly allocated to the intervention group, and six schools (959) were randomly allocated to the control group. A face-to-face questionnaire survey was carried out, R 4.0.3 software was used to analyze the data, and multiple linear regression model was used to analyze the intervention effect. Results After the intervention, mean (standard deviation) scores of self-efficacy among children in the intervention and control groups were (4.4±0.9) and (4.2±1.1), respectively. After the intervention, the proportion of children in the intervention group who underestimated or overestimated their body weight was 28.4% and 11.3%, respectively, while the figures in the control were 37.1% and 6.9%; compared with the control, the risk of underestimating body weight decreased among children in the intervention group(OR=0.64, 95%CI=0.52-0.80, P<0.01), while the risk of weight overestimation increased(OR=1.79, 95%CI=1.26-2.54, P<0.01). After the intervention, the proportion of children in the contemplation or action stage of behaviour change was 65.3% and 83.6%, while the figures in the control group were 59.8% and 69.8%, respectively; in comparison with the control group, more children in the intervention group were in comtemplation (OR=1.28, 95%CI=1.03-1.59, P=0.02) or action stage of behaviour change(OR=2.59, 95%CI=2.04-3.27, P<0.01). Conclusion The comprehensive intervention for childhood obesity improved self-efficacy, weight perception, and facilitated behavior change, but may increase the risk of weight overestimation.
