[Prevalence, control of hypertension and intake of sodium and potassium among residents aged 50-69 years old in Zhejiang Province in 2017].

To understand prevalence, control of hypertension and intake of sodium and potassium among residents aged 50-69 years old in Zhejiang Province. 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. The prevalence of hypertension (95) 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% (=534) of residents had excessive 24 h urinary sodium, and 95.41% (=360) of residents had excessive ratio of 24 h urinary sodium and potassium. 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.
