[目的 ] 研究成人肥胖特点 ,探索有效干预措施。 [方法 ] 对上海市卢湾区 2个社区体重指数 (BMI)≥ 2 5的肥胖成人采取整群抽样法、询问法和问卷式调查 ,并随机抽取其中 3 0 %的肥胖者进行干预前后的对比分析。 [结果 ] 干预后干预组的健康认知程度提高 ,同时有行为发生改变的趋势。表现在对肥胖危害认识和中国居民膳食指南的知晓率明显提高 (P <0 .0 1) ,脂肪摄入量明显下降 ,且摄入总量低于对照组 (P <0 .0 5 ) ;运动频率明显提高 ,完全不运动者由干预前的 5 2 .3 8%下降至干预后的 19.0 5 % (P <0 .0 5 ) ;血清生化方面 ,高密度脂蛋白 -C(HDL -C)有显著上升且明显高于对照组 (P <0 .0 0 5 ) ,而低密度脂蛋白 -C(LDL -C)明显的下降 (P <0 .0 0 1)。 [结论 ] 脂肪摄入过量、运动频率过低、对肥胖控制和预防相关知识的缺乏是当前成人肥胖特点也是控制的关键点。提示在社区进行肥胖干预是可行有效的
[Objective] To study the characteristics of adult obesity and explore effective interventions. [Methods] The obese adults with body mass index (BMI) ≥ 25 in two communities in Luwan District of Shanghai were surveyed by cluster sampling method, questionnaire method and questionnaire survey, and 30% obese people were selected randomly to compare before and after intervention analysis. [Result] After intervention, the health cognition level of the intervention group increased while the behavior changed. The awareness of obesity and Chinese dietary guidelines was significantly improved (P <0. 01), the fat intake significantly decreased, and the total intake was lower than that of the control group (P <0.05). The frequency of exercise was significantly increased from 52.38% before intervention to 19.0 5% after intervention (P <0.05). Serum biochemistry showed that high-density lipoprotein-C (HDL-C ) Was significantly higher than that of the control group (P <0.05), while LDL-C (LDL-C) was significantly decreased (P <0.01). [Conclusion] The excessive intake of fat and the low frequency of exercise, the lack of knowledge about the control and prevention of obesity, are the key points of the current obesity status of adults. Suggesting that obesity intervention in the community is feasible and effective
