摘要:
目的 了解分析安徽省皖北、皖中、皖南三个地区≥40岁人群高血压患病率、意识率、控制率差异及相关危险因素,为不同地区高血压防治提供针对性意见。 方法 以长江、淮河为界,将安徽省分为皖北、皖南、皖中3个地区。采用多阶段分层整群抽样方法,通过问卷调查和体格测量对2015年安徽省≥40岁人群高血压患病、知晓、控制情况以及相关影响因素进行调查。采用χ2检验分析高血压加权患病率、意识率和控制率的地区差异,加权logistic逐步回归分析高血压危险因素,logistic逐步回归分析高血压知晓率和控制率的影响因素。 结果 共纳入2 967名≥40岁的居民。安徽省高血压总体患病率为37.7%(皖中40.1%、皖北38.6%、皖南34.3%),皖北≥60岁人群高血压患病率明显高于皖中、皖南。本次调查高血压知晓率为52.5%,控制率为18.6%,3个地区间差异有统计学意义。皖南高血压知晓率是皖中2.19倍,控制率是其3.88倍,远高于皖北(均P < 0.05)。 结论 安徽省≥40岁人群高血压患病率较高,且皖北高血压控制率远低于皖南,年龄、BMI、文化程度均是影响高血压患病率和控制率的因素。安徽省南北地区、城乡预防卫生保健水平存在较大差异。 Abstract:Objective To analyse the differences in the prevalence, awareness rate, control rate and related risk factors of hypertension amongst people aged ≥ 40 years in North Anhui, Central Anhui and South Anhui and provide targeted suggestions for hypertension prevention and treatment in different regions. Methods Using the Yangtze and the Huaihe River as the boundary, Anhui Province was divided into three areas: North Anhui, South Anhui and Central Anhui. Multi-stage stratified cluster sampling was used to investigate the prevalence, awareness, control and related factors of hypertension in Anhui Province in 2015 using a questionnaire survey and physical measurement. χ2 test was used to analyse the regional differences in the weighted prevalence rate, awareness rate and control rate of hypertension. In addition, weighty logistic stepwise regression was conducted to analyse the risk factors of hypertension. Logistic stepwise regression was used to analyse the influencing factors of hypertension awareness and control rate. Results A total of 2 967 residents aged ≥ 40 years were included in this study. The overall prevalence of hypertension in Anhui Province was 37.7% (40.1% in Central Anhui, 38.6% in North Anhui and 34.3% in South Anhui). The prevalence of hypertension in people aged ≥ 60 years in North Anhui was significantly higher than that in Central Anhui and South Anhui. The awareness rate of hypertension was 52.5%, and the control rate was 18.6%. The difference amongst the three regions was statistically significant. The awareness rate and control rate of hypertension in South Anhui were 2.19 times and 3.88 times as high as those in Central Anhui, which were higher than those in North Anhui, and this difference was significant (all P < 0.05). Conclusion The prevalence of hypertension amongst people aged ≥ 40 years was high in Anhui Province, and the control rate of hypertension in North Anhui was lower than that in South Anhui. Age, BMI and the level of education were considered as factors affecting the prevalence and control rate of hypertension. Great differences in the level of preventive health care were found between North and South of Anhui Province and between urban and rural areas. -
