The prevalence of hyperuricemia and its correlates in an inland Chinese adult population, urban and rural of Jinan

摘要

Economy has developed rapidly in China, and the clustering of cardiovascular risk factors in subjects increased remarkably over the past two decades. However, no data are available regarding the temporal prevalence of hyperuricemia and its correlates in this rapidly developing area, especially in the inland area. The cross-sectional survey was based on a random sample of 4,218 residents aged 35-64 years in the Jinan area. Hyperuricemia was defined as serum uric acid ≥416 μmol/L in men and ≥357 μmol/L in women. Subjects underwent physical examination and fasting blood testing. Complete data were available for analysis from 1,979 men and 2,062 women. The age-adjusted prevalence of hyperuricemia was 6.4 % for men and 2.1 % for women. The prevalence of hyperuricemia was greater in urban (6.7 %) than in rural areas (1.7 %) of Jinan city. Multivariate logistic regression models revealed hyperuricemia associated with hypertriglyceridemia [men: odds ratio (OR) = 6.101, 95 % confidence interval (CI) 4.064-9.159; women: OR = 7.103, 95 % CI 3.578-14.099] and high serum creatinine level (men: OR = 2.603, 95 % CI 1.602-4.230; women: OR = 5.237, 95 % CI 2.667-10.284). Hyperuricemia was also significantly associated with male sex, urban residence, hypertension, obesity, and hypercholesterolemia. Age (1-year increase) was negatively associated with hyperuricemia in men but positively associated with hyperuricemia in women. In conclusion, the prevalence of hyperuricemia is higher in urban than rural areas of Jinan, China. Male sex, urban residence, hypertension, obesity, hypercholesterolemia, hypertriglyceridemia, and high serum creatinine level contributed to hyperuricemia in this population.
