【摘要】 目的 探讨内江市企事业及机关单位从业人员20~60岁人群中超重、肥胖者及其相关因素。 方法 2009年6月－2010年9月采用整体随机分层方法，对内江市企事业及机关单位从业人员共5 832例进行调查。用问卷了解吸烟、饮酒、运动、家族史、文化程度，并测定身高、体重、空腹血糖、甘油三酯、胆固醇等。采用SPSS 17.0软件进行统计学分析，以双侧Plt;0.05为有统计学的意义。与肥胖有关的危险因素采用多因素logistic回归分析。 结果 超重及肥胖者比例为27.16%，其中超重者1 377例，占23.6%，肥胖者207例，占3.55%；肥胖较超重者空腹血糖、甘油三酯、血压更高；多因素logistic回归分析提示:超重及肥胖与年龄、吸烟、性别、运动、家族史、文化程度有关，与饮酒无关。 结论 内江市企事业及机关单位从业人员20~60岁人群中超重、肥胖者比例为27.16%；肥胖较超重者更易发生高血糖、高血压、高血脂、高尿酸血症；超重及肥胖与年龄、吸烟、性别、运动、家族史、文化程度均有关。【Abstract】 Objective To investigate the prevalence and the risk factors of overweight and obesity among employees aged 20 to 60 years old in enterprises and government institutions in Neijiang city. Methods From June 2009 to September 2010, 5 832 employees in government departments, enterprises and institutions in Neijiang were surveyed using stratified random sampling method. Items like physical exercise, smoking, drinking, educational level, and family history were collected through face-to-face questionnaire, and their height, weight, fasting plasma glucose, triglyceride, cholesterol were measured. SPSS 17.0 was used for statistical analysis, and the relationship of each index was analyzed by Pearson correlative analysis. Bilateral Plt;0.05 was considered to be statistically significant. Risk factors associated with obesity were analyzed by Logistic regression analysis. Results The overweight and obesity morbidity rate was 27.16%, including 1377 cases of overweight (23.6%) and 207 cases of obesity (3.55%). Fasting plasma glucose, triglyceride, and blood pressure of obesity patients were higher than those of the overweight patients. Correlation analysis showed that overweight and obesity were positively correlated with fasting plasma glucose (r=0.116,Plt;0.01), triglyceride(r=0.319,Plt;0.01), uric acid (r=0.373,Plt;0.01), diastolic blood pressure (r=0.198,Plt;0.01), and systolic blood pressure (r=0.212,Plt;0.01), but not correlated with cholesterol. Logistic regression multivariate analysis showed that overweight and obesity were related with age, smoking, sex, sports, the educational level and family history, but not related with drinking. Conclusions The prevalence of overweight and obesity among employees aged 20 to 60 years old in enterprises and government institutions in Neijiang city is 27.16%. People with overweight and obesity are more susceptible to hyperglycemia, hypertension, hyperlipemia, and hyperuricemia. Overweight and obesity were closely related with age, smoking, gender, sports activities, family history, and educational level.
