目的 探索以社区为基础的健康教育和健康促进对人群的体质指数、超重或肥胖的影响。方法 于 1991～ 2 0 0 0年期间在北京、上海和长沙三城市各选取 10万社区人群 ,随机分为干预和对照社区各 5万人群。在干预社区开展多种形式的健康教育和健康促进活动 ,评价干预和对照两社区人群KAB水平和体质指数变化。结果 与 1992年基线调查相比 ,在三城市人群和不同目标人群的干预对对照组KAB水平、人群经常运动比率的净提高 ,在统计学上有显著性差异。对照组在全人群体质指数、超重率和肥胖率上升趋势高于干预组 ,其干预对对照组的净降低在统计学上有显著性差异。结论 健康教育和健康促进可有效控制人群体质指数的上升 ,对人群预防心脑血管病具有重要的意义。
Objective To explore the impact of community-based health education and health promotion on the body mass index, overweight or obesity. Methods From 1991 to 2000, 100,000 community residents in each of Beijing, Shanghai and Changsha cities were selected and randomly divided into intervention and control groups of 50,000 residents each. Conducted various forms of health education and health promotion activities in intervention communities, and evaluated KAB levels and BMI changes among intervention and control groups. Results Compared with the baseline survey in 1992, the KAB level in the control group and the net increase in the crowd’s regular exercise rate were significantly different among the three cities and different target groups. In the control group, the body mass index, overweight rate and obesity rate in the whole population tended to rise higher than that in the intervention group. The net reduction of the intervention in the control group was statistically significant. Conclusion Health education and health promotion can effectively control the rise of body mass index, which is of great significance for the prevention of cardiovascular and cerebrovascular diseases in the population.
