ABSTRACT

Objective:To understand the prevalence of hypertension among residents in Keshan disease areas of Sichuan Province, in order to provide scientific basis for prevention and control of hypertension among residents in Keshan disease areas in Sichuan Province in the future.Methods:From 2017 to 2018, Keshan disease case search was carried out in 28 Keshan disease counties (cities, districts, referred to as counties) in Sichuan Province. According to the results of case search, survey sites were selected. Questionnaire survey and blood pressure measurement on permanent residents of the survey sites were conducted according to the unified Keshan disease monitoring plan by professionals. The diagnostic criteria of hypertension refer to the "Chinese Guidelines for Prevention and Treatment of Hypertension" (2019).Results:Totally 24 709 people aged 16 and over were investigated in 28 counties, and 6 022 patients with hypertension were detected, with a detection rate of 24.4% (6 022/24 709); the prevalence of hypertension was 25.5% (2 597/10 199) in male and 23.6% (3 425/14 510) in female; isolated systolic hypertension accounted for 46.5% (2 798/6 022); the constituent ratio of hypertension was 61.9% (3 725/6 022) in grade one, 27.6% (1 665/6 022) in grade two and 10.5% (632/6 022) in grade three.Conclusions:Although the detection rate of hypertension in Keshan disease areas in Sichuan Province is lower than that in the whole country (26.3%), it is still a long-term public health problem. The monitoring of related diseases and health education should be carried out continuously in Keshan disease areas.
