目的了解北京市劳动力人口主要慢性病的流行特征和防治水平,为提高劳动力人口健康水平提供科学依据。方法于2008年10-11月采用多阶段分层随机整群抽样的方法对北京市18～59岁的19314名劳动力人口进行问卷调查、体格测量和实验室检查。结果北京市劳动力人口超重肥胖、中心性肥胖、高血压、血脂异常、糖尿病的年龄标化患病率分别为54.6%、50.0%、31.6%、31.5%、7.5%,男性患病率均明显高于女性(χ2值分别为394.292、669.805、376.568、589.845、90.583,P<0.01),并且随着年龄的增加,患病率升高(趋势χ2值分别为1384.641、1652.408、2140.382、779.054、766.485,P<0.01)。郊区超重肥胖、高血压患病率高于城区,差异均有统计学意义(χ2值分别为39.334、12.045,P<0.01),城区糖尿病、血脂异常患病率高于郊区,差异均有统计学意义(χ2值分别为15.265、46.478,P<0.01)。高血压、糖尿病、血脂异常的治疗率分别为34.4%、47.8%、12.9%,控制率分别为14.3%、27.2%、0,城区高血压、糖尿病控制率高于郊区,差异均有统计学意义(χ2值分别为47.800、5.703,P<0.01)。结论超重肥胖是劳动力人口的主要健康问题,主要慢性病治疗和控制情况不乐观,郊区情势严重。应尽早在工作场所开展生活方式干预。 Objective To understand the epidemiological characteristics and the level of prevention and treatment of the major chronic diseases among the working-age population in Beijing and to provide a scientific basis for improving the health of the working-class population. Methods A questionnaire survey, physical measurement and laboratory tests were conducted among 19,314 labor force population aged 18-59 years in Beijing from October to November in 2008 by using multistage stratified random cluster sampling. Results The age-standardized prevalence of overweight, central obesity, hypertension, dyslipidemia and diabetes in Beijing’s labor force population were 54.6%, 50.0%, 31.6%, 31.5% and 7.5% (Χ2 = 394.292, 669.805, 376.568, 5889.845, 90.583, respectively, P <0.01), and with the increase of age, the prevalence increased (trend χ2 values ​​were 1384.641,1652.408,2140.382,779.054,766.485 respectively, P <0.01). The prevalence of overweight and obesity in suburban areas was higher than that in urban areas (χ2 = 39.334, 12.045, P <0.01). The prevalence of diabetes mellitus and dyslipidemia in urban areas was higher than that in suburbs Significance (χ2 values ​​were 15.265,46.478, P <0.01). The treatment rates of hypertension, diabetes and dyslipidemia were 34.4%, 47.8% and 12.9%, respectively, and the control rates were 14.3% and 27.2% respectively. The control rates of urban hypertension and diabetes were significantly higher than those in the suburbs (χ2 values ​​were 47.800,5.703, P <0.01). Conclusion Overweight and obesity is the major health problem of the labor force population. The treatment and control of the major chronic diseases are not optimistic and the situation in the suburbs is serious. Life style interventions should be initiated in the workplace as soon as possible.
