Abstract:
Objective: To understand prevalence, control of hypertension and intake of sodium and potassium among residents aged 50-69 years old in Zhejiang Province. Methods: A multi-stage random cluster sampling method was used to select 3 032 residents aged 50-69 years old in Zhejiang Province. The demographic characteristics, prevalence and control of hypertension were collected through a questionnaire survey, and physical measurement was also performed. The stratified random sampling method was used to detect the level of sodium and potassium in the 24 h urine of 676 subjects. The total amount of 24 h urinary sodium ≥102.55 mmol and the ratio of 24 h urinary sodium and potassium content ≥2 were defined as excessive. Results: The prevalence of hypertension (95%CI) was 56.89% (54.39%-59.40%), and the awareness, treatment and control rate of hypertension were 58.25% (55.01%-61.49%), 45.37% (42.10%-48.65%) and 19.75% (17.01%-22.50%), respectively. 78.99% (n=534) of residents had excessive 24 h urinary sodium, and 95.41% (n=360) of residents had excessive ratio of 24 h urinary sodium and potassium. Conclusion: The prevalence of hypertension in residents aged 50-69 years old in Zhejiang Province was at a high level, and the control of hypertension was not satisfactory in 2017. Most of residents have excessive level of sodium intake and the level of sodium and potassium intake was not balanced. 目的： 了解浙江省50~69岁人群高血压患病、控制及钠、钾摄入情况。 方法： 2017年1月至5月，采用多阶段随机整群抽样方法，浙江省抽取3 032名50~69岁居民，通过问卷调查收集调查对象的人口学特征、高血压患病和控制情况，并对其进行体格测量。分层随机抽样检测676名调查对象的24 h尿液中钠、钾水平，以24 h尿钠总量≥102.55 mmol和24 h尿钠、钾含量比值≥2判断为超标。 结果： 高血压患病率（95%CI）为56.89%（54.39%~59.40%），高血压知晓率、治疗率和控制率分别为58.25%（55.01%~61.49%）、45.37%（42.10%~48.65%）和19.75%（17.01%~22.50%）。24 h尿钠含量超标率为78.99%（534名），24 h尿钠、钾比值超标率为95.41%（360名）。 结论： 2017年浙江省50~69岁居民高血压患病率处于较高水平，高血压的控制不理想，大多数调查对象钠摄入水平超标，钠、钾摄入水平不均衡。.
