Prevalence of Hypertension and 10-Year Cardiovascular Disease Risk Among Older Adults Living in Quanzhou, A Coastal Region of Southeast China.

Abstract

ObjectiveThis study aims to analyze the prevalence of hypertension and 10-year cardiovascular disease (CVD) risk among older adults living in a coastal region of southeast China.MethodsA population-based cross-sectional survey of 2018 adults was conducted on 60–98-year-old residents in Quanzhou from September 2016 to March 2018 using multistage stratified cluster random sampling. The 10-year CVD risk was estimated by applying the Chinese model recommended by the Chinese guidelines for CVD prevention.ResultsThe overall prevalence of hypertension, prehypertension, and normotension among older adults in Quanzhou was 29.0%, 18.7%, and 52.3%, respectively. The percentage of participants with low, moderate, and high 10-year CVD risk was 49.7%, 36.8%, and 13.5%, respectively. Older age, low salt awareness, and low levels of physical activity were significantly correlated with hypertension. The 10-year CVD risk was higher for men than women and increased with age. Higher blood pressure was associated with a greater 10-year CVD risk.ConclusionMore than half of the older adults in Quanzhou surveyed by this study were normotensive, and approximately half the participants had a moderate or high 10-year CVD risk. We recommend the implementation of regionally targeted interventions, such as screening of blood pressure and other risk factors, to reduce blood pressure and CVD risk in Chinese populations.
