目的 研究超重、中心性肥胖和吸烟（吸烟总量 [TACS] 和状况）之间的关联。设计 基于人群的横断面研究。设置 从中国南京市的三个城区和两个农村县随机选择的行政村和街道（n = 45）。对象和方法 35 岁或以上的当地永久男性居民的代表性样本（n=13,463）；城镇居民占66.5%。答复率为90.1%。根据中国新标准定义超重（BMI≥24）和中心性肥胖（男性腰围≥85）。使用逻辑回归和线性回归分析检查吸烟（数量和状态）与肥胖之间的关联。结果 总体超重率为 36.1%（29.7%，24=28）。调整年龄、居住地、教育程度、职业、家庭收入、饮酒、膳食摄入、职业和休闲身体活动后，当前吸烟者（33.0%）的患病率分别显着低于不吸烟者（39.9%）和戒烟者（39.2%）（p<0.05）。吸烟量与 BMI 呈负相关（与不吸烟者相比，低、中、高 TACS 吸烟者的 OR 和 95% CI 分别为 0.88 [0.79, 0.98]、0.77 [0.69, 0.86] 和 0.77 [0.69, 0.86]）。中心性肥胖患病率为35.9%。与不吸烟者相比，只有男性戒烟者中心性肥胖的风险增加（OR = 1.38，95％CI = 1.10，1.74），而与当前吸烟者没有显着相关性（OR = 1.02 [0.92，1.12]）。吸烟量与向心性肥胖没有显着相关性。结论 在中国男性中，吸烟与以 BMI 为指标的体重呈负相关，但与以腰围为指标的向心性肥胖无关。戒烟可能会增加整体体重增加和发生中心性肥胖的风险。预防和戒烟应成为中国公共卫生的优先事项。
OBJECTIVES To examine the association between overweight, central obesity and cigarette smoking (total amount of cigarettes smoked [TACS] and status). DESIGN Population-based cross-sectional study. SETTING Administrative villages and neighborhoods (n=45) randomly selected from three urban districts and two rural counties in Nanjing City, China. SUBJECTS AND METHODS A representative sample (n=13,463) of permanent local male residents aged 35 years or older; 66.5% were urban residents. The response rate was 90.1%. Overweight (BMI>=24) and central obesity (waist circumference>=85 in men) were defined according to the new Chinese standard. The association between smoking (amount and status) and obesity was examined using logistic and linear regression analysis. RESULTS The overall prevalence of overweight was 36.1% (29.7% with 24=28). After adjusted for age, residence, education, occupation, family income, alcohol drinking, dietary intake, occupational and leisure-time physical activity, the prevalence was significantly lower among current smokers (33.0%) than in non-smokers (39.9%) and ex-smokers (39.2%), respectively (p<0.05). The amount of cigarette smoked was reversely associated with BMI (compared to non-smokers, ORs and 95%CIs for smokers with low-, medium- and high-TACS were 0.88 [0.79, 0.98], 0.77 [0.69, 0.86], and 0.77 [0.69, 0.86], respectively). The prevalence of central obesity was 35.9%. Compared to nonsmokers, only male ex-smokers were at increased risk of central obesity (OR=1.38, 95%CI=1.10, 1.74), while there was no significant association with current- smokers (OR=1.02 [0.92, 1.12]). The amount of cigarette smoked was not significantly associated with central obesity. CONCLUSIONS Cigarette smoking was negatively associated with body weight indicated by BMI but not with central obesity indexed by waist circumference in Chinese men. Cessation of smoking may increase the risk of gaining overall body weight and developing central obesity. Cigarette smoking prevention and cessation should be a public health priority in China.
