东北地区城市居民脑卒中多因素人群归因危险度分析

Investigation of population attributable risk of stroke′s risk factors among urban adult groups in northeast China

目的利用调整人群归因危险度及综合人群归因危险度评价东北地区城市居民脑卒中的危险因素,为开展预防治疗工作提供科学依据。方法按地理经济水平随机抽取辽宁省沈阳、鞍山和锦州3个城市,采用分层随机抽样对11个行政区≥35岁的17 170名城区常住(≥5年)居民进行调查。由培训过的医师对调查对象进行了血压测量和常见脑卒中危险因素资料的收集。结果东北地区城市居民的主要危险因素为年龄、性别、吸烟、腰围、高血压、高血脂和脑卒中家族史,其调整人群归因危险度分别为47.9%、28.8%、3.9%、10.6%、44.2%、17.5%和13.9%,7个因素综合人群归因危险度为83.4%。结论利用调整人群归因危险度和综合人群归因危险度对脑卒中危险因素的评价及制定相应防治策略方面有较高的价值;对高危人群开展脑卒中等慢性病预防的健康教育和治疗的干预措施可有效地降低其患病率。

Objective To estimate the stoke′s risk factors in urban residents from northeast China by using corrected population attributable risk（PARc%） and synthesized population attributable risk（sPAR%）,and to provide scientific basis for preventing and intervene measurement of stroke.Methods Three cities in Liaoning Province（Shenyang,Anshan and Jinzhou） were randomly selected according to the condition of economic geographly.Through cluster random sampling to a resident（≥5 years） group of 17 170 people aged more than 35 years old in 11 districts of selected cities.The blood pressure measurement and correlative risk factors about stroke were investigated by trained doctors.Results The majority risk factors of stroke in northeast urban area are age,sex,smoking,waistline,hypertension,hyperlipemia and family stroke history,and the PARc% of these seven risk factors are 47.9%,28.8%,3.9%,10.6%,44.2%,17.5% and 13.9%,respectively.The sPAR% of these seven risk factors are 83.4%.Conclusion It has high value to estimate stroke′s risk factors and to formulate prevention and crue strategy by using PARc% and sPAR%.It can degrade the stroke′s prevalence of the high-risk group effectively by evolving healthy education of prevention and therapy of intervention study.
