[目的]对昆明市农村汉族和彝族村民吸烟行为与BMI指数和腰围的关系进行对比分析。[方法]在昆明市石林县采用PPS抽样方法对6006名45岁以上村民通过问卷调查和体格检查获取所需资料。[结果]汉族的肥胖率明显高于彝族(χ2=4.88,P﹤0.01)。汉族与彝族村民的中心性肥胖率、汉族男性与彝族男性腰围的分布无差别(χ2=1.48,P﹥0.05);但汉族女性的中心性肥胖率明显高于彝族女性(χ2=3.97,P﹤0.01)。汉族和彝族吸烟者与未吸烟者的肥胖率和中心性肥胖率没有差别(χ2=1.06,P﹥0.05),但不吸烟者的超重率和体重过轻者的比率均明显高于吸烟者(χ2=4.21,P﹤0.01)。[结论]应在农村居民中开展戒烟的健康教育,特别是在汉族村民中加强合理饮食的健康教育,以减少超重和中心性肥胖的发生。
[Objective] To compare the relationship between smoking behavior and BMI index and waist circumference among Han and Yi villagers in rural areas of Kunming. [Method] The PPS sampling method was adopted in Shilin County, Kunming City to get the necessary information on 6006 villagers aged 45 and above through questionnaire and physical examination. [Results] The obesity rate of Han people was significantly higher than that of Yi people (χ2 = 4.88, P <0.01). The central obesity rate of Han and Yi villagers did not differ between Han and Yi men (χ2 = 1.48, P> 0.05); however, the central obesity rate of Han women was significantly higher than that of Yi women (χ2 = 3.97, P < 0.01). There was no difference between obesity rate and central obesity rate in Han and Yi smokers and non-smokers (χ2 = 1.06, P> 0.05), but the rates of overweight and underweight among non-smokers were significantly higher than those of smokers χ2 = 4.21, P <0.01). [Conclusion] Health education should be carried out among rural residents to stop smoking. In particular, health education should be strengthened among villagers in the Han nationality to reduce the incidence of overweight and central obesity.
