Prehypertension is a new category of blood pressure (BP) classification according to the Seventh Report of The Joint National Committee. Little is known about the epidemiology of prehypertension in rural China. The purpose of the present study is to determine the prevalence of prehypertension and associated risk factors in rural adult people of China.
Through cluster multistage and random sampling method, a resident group of 29,970 people aged > or =35 years old in Liaoning Province was selected from 2004 to 2005. The survey on BP and associated risk factors was carried out. Prehypertension was defined as systolic BP between 120 and 139 mmHg or diastolic BP 80 and 89 mmHg. Overall, the prevalence of prehypertension was 47.0%, males 51.2% and females 42.6%, respectively. The prevalence of hypertension was 36.2%. Multivariable logistic regression showed overweightness, obesity and drinking were risk factors of prehypertension. Female and greater than high school education status were shown as protective factors.
The prevalence of prehypertension of rural adult people in China is dramatically high and it was associated with many risk factors. Comprehensive lifestyle modifications are needed to be taken to decrease the incidence of prehypertension and to prevent prehypertension people from hypertension and cardiovascular disease.
根据美国国家联合委员会第七次报告，高血压前期是一种新的血压分类类别。在中国农村地区，关于高血压前期的流行病学情况知之甚少。本研究的目的是确定中国农村成年人中高血压前期的患病率及相关危险因素。
通过整群多级随机抽样方法，于2004年至2005年选取了辽宁省29970名年龄≥35岁的居民群体。对血压及相关危险因素进行了调查。高血压前期定义为收缩压在120至139mmHg之间或舒张压在80至89mmHg之间。总体而言，高血压前期的患病率为47.0%，男性为51.2%，女性为42.6%。高血压的患病率为36.2%。多变量逻辑回归显示超重、肥胖和饮酒是高血压前期的危险因素。女性和高中以上文化程度为保护因素。
中国农村成年人高血压前期的患病率极高，且与多种危险因素相关。需要采取综合的生活方式干预措施来降低高血压前期的发病率，并预防高血压前期人群发展为高血压和心血管疾病。
