Abstract:
Objective To investigate the prevalence and related factors of hypertension among elderly population in Fujian Province. Methods We extracted data of 4 483 elderly residents(aged≥60 years) from a stratified multi-stage random sampling cross-sectional survey on hypertension in Fujian Province from August 2014 to July 2016. Prevalence, awareness, treatment and control rates of hypertension were calculated. We compared the prevalence of hypertension between genders and residential areas(coastal or inland, rural or urban), then analyzed related factors of hypertension. Results The overall crude prevalence of hypertension among elderly in Fujian Province was 60.2%, and the weighted prevalence was 59.1%, while the awareness, treatment and control rates were 55.8%, 50.1% and 17.0%, respectively. The prevalence of hypertension was significantly higher in women(63.2% vs 57.1%, P<0.05), but awareness, treatment and control rates showed no gender difference(55.9% vs 55.6%, 50.6% vs 49.6%, 17.6% vs 16.6%, P>0.05, respectively). Urban elderly residents had similar prevalence of hypertension with rural elderly residents(59.1% vs 61.4%, P>0.05), but were more awared and better treated and controled(60.2% vs 51.5%, 56.1% vs 44.4%, 25.4% vs 8.8%, P<0.05, respectively). Elderly residents in coastal areas had higher prevalence and severity(level 2 to 3) of hypertension(77.0% vs 55.9%, 25.9% vs 15.3%, 15.5% vs 5.6%, P<0.05, respectively) than in inland areas. Related risk factors of hypertension in the elderly population included age, central obesity, education level, family history of hypertension, body fat percentage and body mass index. Conclusions The prevalence of hypertension among elderly population in Fujian Province is relatively high, especially in women, and those with central obesity or living in coastal areas. Meanwhile, the awareness, treatment, and control rates of hypertension in old population remain low.
