目的 了解广东省居民单纯收缩期高血压 (ISH)的流行病学特征。方法 利用 2 0 0 2年广东省居民营养与健康状况调查资料 ,进行ISH描述性流行病学分析。结果 广东省 1 5岁及以上居民ISH粗患病率为 8 1 % (标化率为 5 3% ) ,其中男性为 7 6 % (标化率为 4 7% ) ,女性为 8 4 % (标化率为 5 9% ) ,男女性标化患病率差异有显著性 (u =2 97,P <0 0 1 ) ;35岁以前男性ISH患病率高于女性 ,35～ 74岁则女性高于男性 ;ISH总患病率随年龄增长而迅速增高 ;低收入、高文化程度者、学生、干部的ISH患病率较低 ,ISH患病率随着体质指数、腰围的增加而增高 ;与 1 991年相比 ,ISH标化患病率总体差异无显著性 (u =1 94 ,P >0 0 5 )。结论 ISH以老年人多见 ,随年龄增长而迅速增高 ;预防控制ISH要从早期开始并以控制肥胖为主
Objective To understand the epidemiological characteristics of isolated systolic hypertension (ISH) in Guangdong province. Methods Based on the survey data of nutrition and health status of residents in Guangdong Province in 2002, the descriptive epidemiological analysis of ISH was carried out. Results The crude prevalence of ISH was 15% (standardized rate was 53%) in residents aged 15 years and older in Guangdong Province, of which 76% were male (47% standardized) and 84% female The standardization rate was 59%). The standardized prevalence of male and female was significantly different (u = 2 97, P <0.01). Before age 35, the prevalence of ISH was higher in males than in females and 35-74 years The prevalence of ISH increased rapidly with age. The prevalence of ISH among low-income and high-education students, students and cadres was lower, and the prevalence of ISH increased with the increase of body mass index and waist circumference The prevalence of ISH was not significantly different from that in 1991 (u = 1 94, P> 0.05). Conclusion ISH is more common in the elderly and increases rapidly with age. The prevention and control of ISH should be controlled from the early stage and controlled mainly by obesity
