Abstract:
Objective To explore the epidemiological status and risk factors of hyperuricemia in rural area of the Three Gorges.Methods A cross-sectional survey was carried out in rural area of Yiling District,Yichang City,which was located north-west bank of Xiling Gorge in 2007.A standard structure questionnaire was used to collect demographic data,social-economic status and life-style features.Fasting venous blood was collected and serum uric acid (SUA) was determined.Hyperuricemia was defined as SUA levels ≥ 417 μmol/L (70 mg/L) in men and ≥ 357 μmol/L (60 mg/L) in women.Multiple logistic regression analysis was used to analysed the risk factors of hyperuricemia.Results A total of 9354 participants aged 35 and above were included,19.9％ (1866/9354) participants were the Three Gorges migrants.Serum uric acid level in men was significantly higher than that in women[(285.1 ± 80.2) μmol/L vs.(210.3-65.0)μ mol/L,P ＜ 0.01].Serum uric acid level increased significantly in both genders in proportion to increase of age,and was higher in men than in women in all age groups (all P ＜ 0.01).The age-adjusted prevalence was significantly higher in men than in women (5.6％ vs.3.3％,P ＜0.01),and was also higher in men aged 35-44 and aged 45-54 than in women (both P ＜ 0.01).There was no significance in prevalence of hyperuricemia in both men and women aged 55-64 and aged ≥ 65.After adjusting age,gender,educational level,migration and occupation,the multiple logistic regression analysis showed that the prevalence of hyperuricemia was higher in alcohol drinking participants than that of nonalcohol drinking participants (OR =2.06,95％ CI:1.59-2.67,P ＜ 0.01),and in participants used to consume less green vegetables and fruits than in participants consuming more green vegetables and fruits (OR =1.77,95％ CI:1.27-2.47,P ＜ 0.01).Conclusions The prevalence of hyperuricemia is relatively low in rural area of the Three Gorges.Alcohol drinking and low intake of green vegetables and fruits are the risk factors of hyperuricemia in this population.
