目的了解烟台市不同性别老年人肥胖与糖尿病发病的关系。方法采用分层整群随机抽样的方法，对烟台市莱山区、蓬莱市、栖霞市和海阳市4个区市抽取的986名≥60周岁的老年人进行问卷调查、体格检查和血糖检测，应用Logistic回归模型分析烟台市不同性别老年人肥胖与糖尿病的关系。结果烟台市老年人肥胖率和腹型肥胖率分别为10．04％和60．85％，糖尿病的患病率为10．85％。调整年龄、文化程度、月收入、既往工作性质、吸烟和饮酒等因素后，肥胖老年人患糖尿病的危险为正常体重老年人的3．121倍（OR=3．121，95％CI1．978～5．119），并且肥胖与患糖尿病存在性别差异，仅男性肥胖与患糖尿病的关系有统计学意义（OR=3．924，95％CI1.61—7．174），腹型肥胖老年人患糖尿病的危险为非腹型肥胖老年人的2．398倍（OR：2．398，95％CI2．123—4．412），并且腹型肥胖与患糖尿病存在性别差异，仅男性腹型肥胖与患糖尿病的关系有统计学意义（OR=2．917，95％CI1．249～4．019）。结论烟台市老年人肥胖、腹型肥胖与糖尿病关系存在性别差异，可把体质指数和腰围作为男性糖尿病发病的预测指标。

And there was a gender difference between diabetes and obesity. The cross-sectional association between the incidence of diabetes and masculine obesity was of statistical significance alone （ OR = 3. 924,95% CI 1. 561 - 7. 174）. The elderly with the abdominal obesity 2. 398 times as likely to suffer from diabetes as the elderly with the non-abdominal obesity （ OR = 2. 398,95% CI 2. 123 - 4. 412 ）. There was a gender difference between diabetes and abdominal obesity.
