Investigation of the prevalence of hyperuricemia in the elderly people in a community in Shanghai and analysis of the influence factor

Objective: To investigate the incidence rate of hyperuricemia in the population over 65 years old who had the physical examination in Dapuqiao Community in Shanghai to early find out the patients with asymptomatic hyperuricemia and analyze the related risk factors. Methods: In 2013, 1 540 cases over 65 years old were collected in Dapuqiao Community in Shanghai, among them 680 were the male and 860 the female. The prevalence of hyperuricemia and the differences between the male and female were investigated. At the same time, the patients were divided into a hyperuricemia group with 541 cases and a control group(no hyperuricemia group) with 999 cases according to the level of uric acid and the relative risk factors which caused hyperuricemia were analyzed. Results: The incidence rate of hyperuricemia was 35.13%(541/1 540), and among them, the male accounted for 35.44%(241/680), and the female 34.88%(300/860), and the differences had no statistical significance(P0.05). The logistic regression analysis found that the old age, high BMI, hypertriglyceridemia, high creatinine, high blood urea nitrogen, and others were the risk factors of hyperuricemia but the high HDL cholesterol level was the protective factor(P0.01). Conclusion: Hyperuricemia is associated with a variety of metabolic diseases and the elderly people have the high prevalence of hyperuricemia. It is suggested that the regular blood uric acid level be tested for the elderly people over 65 years old to find out the patients and intervene them early.
