Hypertension is frequently studied in surveys; however, prehypertension, a new blood pressure status between normotension and hypertension, is rarely reported.
All data were derived from the China Health and Nutrition Survey (CHNS) and were analysed by logistic regression for correlation.
The prehypertension prevalence was 27.4%, with a hypertension rate of 36.9%. The awareness, treatment, and uncontrolled rates among all hypertension participates were 19.8%, 83.6%, and 55.0%, respectively. The epidemic rate of hypertension increased with increasing age (p < 0.001), and prehypertension appeared to have an epidemic peak in the age group of 38-57 years (p < 0.001). In general, the incidence of hypertension in urban participants was higher than in rural subjects (p < 0.001), and prehypertension in urban subjects was lower than that in rural subjects (p < 0.001). According to the results of logistic regression, hypertension and prehypertension were associated with age, gender, location, body mass index (BMI), body fat rate (BFR), waist circumference (WC), education, and the intake of energy-yielding nutrients<0.05).
The current study reveals a high epidemic rate of hypertension and prehypertension in Central China. These results indicate the urgent need to develop strategies to improve the prevention of hypertension and prehypertension in Central China.
高血压在调查中经常被研究；然而，血压在正常和高血压之间的新状态——前期高血压，很少被报道。
所有数据均来自中国健康与营养调查（CHNS），并通过逻辑回归进行相关性分析。
前期高血压的患病率为 27.4%，高血压的患病率为 36.9%。所有高血压患者的知晓率、治疗率和未控制率分别为 19.8%、83.6%和 55.0%。高血压的流行率随年龄的增加而增加（p<0.001），前期高血压在 38-57 岁年龄组出现流行高峰（p<0.001）。一般来说，城市参与者的高血压发病率高于农村居民（p<0.001），而城市居民的前期高血压发病率低于农村居民（p<0.001）。根据逻辑回归的结果，高血压和前期高血压与年龄、性别、地点、体重指数（BMI）、体脂率（BFR）、腰围（WC）、教育程度和能量产生营养素的摄入量有关（p<0.05）。
本研究揭示了中国中部地区高血压和前期高血压的高流行率。这些结果表明，迫切需要制定策略，以改善中国中部地区高血压和前期高血压的预防。
