摘　　要：目的了解广东省居民脑卒中患病情况及其危险因素。方法运用多阶段整群随机抽样方法,抽取广东省大城市、中小城市、2类农村各3个区(县),1类农村4个县,每个县(区)抽取3个街道(乡)、6个居委,每个居委抽取90户,对抽取户的15岁及以上居民用面对面询问方法获得其个人基本情况,体检获取体重、身高、血压数据,血脂使用统一的方法进行检测。结果共调查15岁及以上居民17857人。脑卒中的粗患病率为789/10万,年龄标化患病率为600/10万。城乡粗患病率分别为1208/10万、416/10万,差异有统计学意义(P<0.01)。男女粗患病率分别为953/10万、655/10万,差异有统计学意义(P<0.05)。不论城乡、性别,脑卒中的患病率随年龄的增加而上升。高血压、脑卒中家族史、超重者、戒酒者、血脂异常者、轻职业性体力活动等人群脑卒中的患病率较高。生存的脑卒中患者平均发病年龄为57岁,8.4%的患者在45岁前发病,80.0%在45～74岁发病。根据分类树分析,脑卒中的主要危险因素为高血压、年龄高、轻职业性体力活动、高胆固醇、居住在城市和低高密度脂蛋白。结论脑卒中是危害广东省居民健康的一种严重疾病,增加体力活动、保持良好的饮食习惯和防治高血压是预防控制脑卒中的主要措施。Objective To describe the prevalence rate and influencing factors of stroke in Guangdang Province. Methods A representative people sample was selected through multi - stage randomized cluster sampling. Data of socioeconomics and stroke status were collected by face - to - face interview. The data of weight, height and blood pressure were obtained by physical examination. The blood lipid was detected. Results A total of 17 857 people were selected. The crude prevalence of stroke was 789/100 000, and the age - adjusted rate was 600/100 000. There were significant differences for crude rate between urban （ 1 208/100 003） and rural （416/100 000）, and male （953/100 000） and female （655/100 000）. The stroke prevalence rate increased with age. The population with hypertensive, or stoke - history, or overweight, or alcohol - quitting, or abnormal blood lipid or light physical activity had high prevalence of stroke. The average age of stroke onset was 57 years old. At the onset age, 8.4% of patients were before 45 years old, and 80.0% were between 45 - 74 years old. Using regression and classification tree method, the major risky factors of stroke were hypertension, aging, light physical activity, high blood eholesterin, urban residents and low blood high density lipoprotein. Conclusion Stroke was a serious disease which threated Guangdong people＇s health. Increasing physical activity, improving dietary pattern and prevention hypertension were important measures to prevent and control stroke.
