目的调查60~79岁成渝地区城市社区高血压人群的糖尿病患病率,探讨该人群糖尿病患病的影响因素。方法采取分层抽样的方法,调查成都及重庆城市社区60~79岁的老年高血压患者2135例,所有患者均安排空腹血糖检查。没有糖尿病病史的老年高血压人群口服葡萄糖耐量实验(OGTT),调查对象安排统一的问卷调查。统计分析该人群糖尿病患病率及分布特点,分析该人群患糖尿病的影响因素。结果成渝地区城市社区老年高血压人群的糖尿病患病率为39.6%。女性患病率(42.9%)高于男性患病率(35.0%)(P<0.01)。老年高血压人群糖尿病患病率随年龄的增加呈逐渐增加趋势(P=0.02)。59.9%糖尿病患者为本次调查新诊断的患者。年龄、较高的收入水平、糖尿病家族史、超重或肥胖、高甘油三酯血症为老年高血压人群患糖尿病的危险因素,体育锻炼为老年高血压人群患糖尿病的保护因素。结论成渝地区城市社区60~79岁老年高血压人群糖尿病患病率高,且大部分患者既往未诊断,漏诊率高,应加强检测,及时发现大量的漏诊患者。
