Associations between anthropometric parameters (body mass index, waist circumference and waist to hip ratio) and newly diagnosed hyperuricemia in adults in Qingdao, China: A cross-sectional study

摘要

Background and Objectives: To evaluate the association between anthropometric parameter of obesity and newly diagnosed hyperuricemia (HUA) in a general Chinese population. Methods and Study Design: A population-based cross-sectional survey included 9 615 participants (3777 men and 5838 women) aged 35-74 years in 2006 and 2009 in Qingdao, China. The multivariate linear regression was used to assess the linear associations between anthropometric parameter of obesity [body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR)] and serum uric acid. The logistic regression model was performed to estimate the associations between BMI, WC, WHR and newly diagnosed HUA. Results: The prevalence of newly diagnosed HUA was higher in men than in women (19.46% vs 11.34%, p<0.05). Multivariate liner regression showed that BMI, WC and WHR were positively correlated with serum uric acid. Multivariate logistic regression revealed that being overweight [men, odds ratios (OR): 1.69, 95% confidence intervals (95% CI): 1.37-2.08; women, OR: 1.67, 95% CI: 1.34-2.09] and obese (men, OR: 3.01, 95% CI: 2.38-3.79; women, OR: 2.91, 95% CI: 2.31-3.67) were significantly associated with a higher risk of newly diagnosed HUA. Abdominal obesity (WC: men, OR: 2.26, 95% CI: 1.88-2.73; women, OR: 1.96, 95% CI: 1.61-2.39; WHR: men, OR: 1.91, 95% CI: 1.61-2.26; women, OR: 1.39, 95% CI: 1.16-1.67) were associated with an increased risk of newly diagnosed HUA. Conclusions: This study demonstrated that BMI, WC and WHR were positively correlated with serum uric acid in both genders. Meanwhile, overweight, obese and abdominal obesity were associated with increased risk of newly diagnosed HUA.
