甘肃省榆中农村居民心血管病主要危险因素分布与聚集情况分析

目的：了解甘肃榆中县农村居民心血管病危险因素的分布与聚集情况，为实施心血管疾病干预措施提供依据。方法采用整群随机抽样的方法，于2013年6月抽取了甘肃省榆中县35周岁以上农村居民1185名，进行心血管病危险因素流行病学调查，分析危险因素的聚集情况。结果①研究人群高血压患病率、吸烟率、超重率、肥胖率、血脂异常率和糖尿病患病率依次为26.4%、28.9%、34.9%、8.6%、46.2%和7.0%，其中高血压患病率（χ^2=83.583，P〈0.001）、血脂异常率（χ^2=5.705，P〈0.01）和糖尿病患病率（χ^2=17.557，P〈0.001）随年龄增高而升高，男性吸烟率（60.6%）高于全国平均水平（53.3%），女性肥胖率高于男性（χ^2=3.850，P〈0.05）。②具有1个及以上心血管病危险因素的个体比例高达84.0%，男性较于女性更严重，差异有高度统计学意义（P〈0.01）。结论榆中县农村居民心血管病危险因素超重、肥胖和血脂异常比例高，且危险因素聚集现象严重，应针对重点人群积极开展心血管疾病危险因素的干预措施。

Main risk factors for cardiovascular disease in Yuzhong County,Gansu Province rural distribution and aggregation analysis

Objective To master the Yuzhong County, Gansu Province rural residents cardiovascular disease risk fac-tors distribution and aggregation case, in order to provide the basis for the implementation of cardiovascular disease interventions. Methods Used cluster random sampling method, sampled of 1185 cases, whose ages were older than 35 in Yuzhong County, Gansu Province, in June 2013 was extracted. Epidemiological investigation of cardiovascular dis-ease risk factors was carried and the risk factors gathered case was analyzed. Results ①The prevalence rate of hyper-tension, smoking, overweight, obesity, lipid disorder and diabetes were 26.4%, 28.9%, 34.9%, 8.6%, 46.2% and 7.0%. The prevalence of hypertension （χ^2=83.583, P〈0.001）, dyslipidemia （χ^2=5.705, P〈0.01） and diabetes prevalence （χ^2=17.557, P〈0.001） increased with age rises, male smoking rate （60.6%） was higher than the national average （53.3%）, fe-male＇s obesity rate was higher than male （χ^2= 3.850, P〈0.05）. ②The proportion of individuals had one or more risk factors for cardiovascular disease up to 84.0%, males were more serious than females, the differences were statistically significant （P〈0.01）. Conclusion The proportion of rural residents of cardiovascular disease risk factors of overweight, obesity and dyslipidemia are higher in Yuzhong County. At the same time the risk factors clustering phenomenon are seriously. The interventions for cardiovascular disease risk factors for the focus groups should be actively carried out.
