High prevalence and low awareness of hyperuricemia in hypertensive patients among adults aged 50–79 years in Southwest China

INTRODUCTION: This study was aimed to assess the prevalence of hyperuricemia and its associated risk factors among hypertensive patients in Southwest China. METHODS: From September 2013 to March 2014, a multistage, stratified sampling was conducted on 3505 hypertensive people aged 50–79 years who lived in urban communities within Chengdu and Chongqing, using a questionnaire and performing physical and biochemical measurements. RESULTS: In the study population, approximately 18.2% of all hypertensive participants had hyperuricemia (638/3505), with a prevalence rate of 21.5% in men and 16.2% in women (p < 0.05). Multivariate logistic regression analysis showed that aging, without spouse, current drinking, preferring hotpot, hypertriglyceridemia, BMI ≥ 25 kg/ m(2), and central obesity were all positively correlated with hyperuricemia, whereas female gender was negatively correlated with hyperuricemia. The prevalence of hyperuricemia among hypertensive patients in urban adults aged 50–79 years in southwestern China was high, while levels of awareness were extremely low. DISCUSSION: Improved hyperuricemia health knowledge should be delivered to improve public awareness of the disease and it may need aggressive strategies aiming at the prevention and treatment of hyperuricemia. It is may necessary to encourage people to check blood uric acid levels when they first time to be diagnosed with hypertension, especially in the elderly.
