目的 分析广东省居民低血压流行病学特征。方法 采用多阶段分层整群随机抽样方法 ,抽取新兴县、广州市越秀区等 1 3个市 (县、区 ) ,所有抽中家庭的 1 5岁及以上人口作为调查对象。被调查对象收缩压 (SBP)≤ 98mmHg并且舒张压 (DBP)≤ 6 0mmHg为低血压。采用 1 990年全国人口普查数据进行标化 ,并与 1 991年高血压调查数据进行比较。结果 共调查 1 5 4 74人 ,1 5岁及以上居民低血压粗患病率为 4 0 % ,其中男性为 2 4 % ,女性为 5 2 % ,女性高于男性 (χ2 =87 4 7,P <0 0 1 ) ;标化患病率为 5 7% ,其中男性为 3 4 % ,女性为 7 3% ,女性高于男性 (Z =1 4 72 ,P <0 0 1 )。随着年龄的增加 ,男女性低血压的患病率均呈下降趋势 (趋势 χ男2 =1 5 9 2 6 ,χ女2 =1 78 0 0 ,χ总2 =31 7 96 ,P值均 <0 0 1 ) ;低血压患病率随文化程度、工作种类的改善而升高 ;农村患病率较城市高 ;单身者较有配偶者患病率高。与 1 991年相比 ,2 0 0 2年广东省居民低血压的标化患病率降低 (Z =2 98,P <0 0 1 ) ,女性除 1 5～岁年龄组外 ,其他年龄组低血压患病率均降低 ,男性低血压患病率除 1 5～岁年龄组升高外 ,其他年龄组无变化。结论 广东省低血压患病率在不同人群的分布相差较大 ,低年龄、女性、高文化程度、国
Objective To analyze the epidemiological characteristics of hypotension among residents in Guangdong Province. Methods A multistage stratified cluster random sampling method was used to select 13 counties (counties and districts), including Xinxing County and Yuexiu District of Guangzhou City, among which the population aged 15 and over was selected as the survey target. Subjects to be investigated systolic blood pressure (SBP) ≤ 98mmHg and diastolic blood pressure (DBP) ≤ 600mmHg for hypotension. Using the data from the 1990 national census, the data were standardized and compared with the data from the 1999 hypertension survey. Results A total of 1 5474 people were surveyed. The prevalence of hypotension was 40% in residents aged 15 and over, including 24% in males and 52% in females, and higher in females than in males (χ2 = 87.47, P <0.01). The standardized prevalence rate was 57%, including 34% in males and 73% in females and higher in females than in males (Z = 1472, P <0.01). The prevalence of hypotension among men and women showed a decreasing trend with age (trend χ2 = 151926, χ2 = 1780, χ2 = 31 7 96, P values <0 0 1). The prevalence of hypotension increased with the improvement of educational level and work types. The prevalence rate in rural areas was higher than that in urban areas. The prevalence of single spouses was higher than that of spouses. Compared with 1991, the prevalence of hypotension was lower in Guangdong residents (Z = 2 98, P 0 01) in 2002. In addition to the age group of 1 5 ~, women of other age groups The prevalence rate of hypotension was decreased. The prevalence of hypotension in men was not changed in other age groups except for the increase in 15 ~ age group. Conclusions The prevalence of hypotension in Guangdong Province varies greatly among different groups of people, with a low age, women, high education level,
