目的研究分析成都市中心城区居民血脂异常患病率及合并心血管危险因素的现状。方法采用分层整群抽样的方法,于2010年2月-10月间共调查14个中心城区居委会中35~70岁常住(2年以上)居民994人,根据年龄划分为3组:青年组(年龄≤44岁),中年组(年龄45~59岁)和老年组(年龄≥60岁)。进行问卷、体格检查和实验室检查。进一步调查血脂异常患者合并的主要心血管危险因素。结果成都市区居民血脂异常的患病率为28.47%(283/994),标准化患病率为24.65%,其中男性24.68%,女性30.91%,不同性别间患病率有显著性差异(χ2=4.513,P=0.034);女性老年组和中年组患病率高于青年组,差异有统计学意义(P<0.05);男性各年龄组患病率差异无统计学意义(P>0.05)。血脂异常人群中合并高血压最多,男性和女性分别为50.04%(49/96)和52.41%(98/187),其次为合并糖尿病和冠状动脉粥样硬化性心脏病(冠心病);血脂异常合并高血压、脑卒中史、冠心病史、腹型肥胖和肥胖的人群中,不同性别之间差异无统计学意义(P>0.05);男性血脂异常人群中吸烟和饮酒的比例高于女性,差异有统计学意义(P<0.05)。结论成都市城市社区居民血脂异常患病率较高,应针对该地区血脂异常的流行病学特征及危险因素,采取综合措施,降低血脂异常患病率。
Objective To study and analyze the prevalence of dyslipidemia and cardiovascular risk factors in urban centers of Chengdu. Methods A stratified cluster sampling method was used to survey 994 residents aged 35-70 years (over 2 years) in 14 central urban neighborhoods from February to October 2010, and divided into 3 groups according to their ages: young group (≤44 years of age), middle-aged (45-59 years of age), and elderly (≥60 years of age). Conduct questionnaires, physical examination and laboratory tests. Further investigation of major cardiovascular risk factors associated with dyslipidemia. Results The prevalence of dyslipidemia in urban residents in Chengdu was 28.47% (283/994). The standardized prevalence was 24.65% in men and 24.68% in men and 30.91% in women. There was a significant difference in prevalence among different sexes (χ2 = 4.513, P = 0.034). The prevalence rate in elderly women and middle-aged women was higher than that in youth group (P <0.05). There was no significant difference in the prevalence among all age groups (P> 0.05) . Patients with dyslipidemia had the most hypertension, with 50.04% (49/96) and 52.41% (98/187) respectively in men and women, followed by those with diabetes and coronary heart disease (CHD); dyslipidemia There were no significant differences among different sexes in those with hypertension, history of stroke, history of coronary heart disease, abdominal obesity and obesity (P> 0.05). The prevalence of smoking and drinking in men with dyslipidemia was higher than that in women, The difference was statistically significant (P <0.05). Conclusion The prevalence of dyslipidemia is high in urban community residents in Chengdu. In view of the epidemiological characteristics and risk factors of dyslipidemia in the area, comprehensive measures should be taken to reduce the prevalence of dyslipidemia.
