Epidemiological Relativity Study of Hyperuricemia with Factors of Purine-rich Food, Obesity, and Drinking

Objective To investigate the prevalence of hyperuricemia and its associated factors including purine-rich food,obesity, and drinking in some population in Beijing. Methods A cross-sectional study of hyperuricemia was carried out in state-employees who had yearly health examination at our hospital in Beijing from September to December 2005. The prevalence of hyperuricemia was calculated in the population. The form of food frequency was used to understand the intake status of purine-rich food. Data were further analyzed by multivariate logistic regression models to identify the risk factors of hyperuricemia. Results The prevalence of hyperuricemia in the population was 10.9%, and was 13.8% and 6.3% in men and women, respectively. Bivariate and multivariate logistic regression analysis showed that male gender, hard liquor, overweight/obesity, waist obesity, hypercholesterolemia, and hypertriglyceride were associated with increased prevalence of hyperuricemia (P0.05) ; however, products of nutrient buillon, seafood, animal organs, and mushroom had no significant association with the prevalence of hyperuricemia in either men or women. The products of nuts, nutrient buillon, and eating in restaurant were significantly associated with the prevalence of overweight and obesity in women(P0.05), was no significantly associated with the prevalence of hyperuricemia. Conclusions Male gender, hard liquor, waist obesity, hypercholesterolemia, and hypertriglyceride may increase the prevalence of hyperuricemia in some populations in Beijing. The purine-rich food may not be a risk factor of hyperuricemia.
