Epidemiology of hyperuricemia in the elderly.
BACKGROUND
Our study used data collected in Chung-Hsing Village to evaluate the relationship between hyperuricemia and the cardiovascular risk factors and the socio-demographic factors in the elderly in May 1998.


METHODS
All individuals aged 65 and over were studied. A total of 1093 subjects, out of 1774 registered residents, were contacted by face-to-face interview. The response rate was 61.6 percent. However only 586 respondents had blood tests and completed questionnaires. Analysis in this study was based on these 586 subjects. To study the significant correlates of hyperuricemia, t- test, two-way ANOVA, chi-square test and multivariate logistic regression were used.


RESULTS
Our results showed that 66 percent were men and 34 percent were women. The mean age was 73.1+/-5.3 years. The proportions of hyperuricemia were 57.3 percent in men and 40.9 percent in women (p < .01). In chi-square test, hypercholesterolemia, hypertriglyceridemia, renal function impairment, retirement status and marital status were related to hyperuricemia. After controlling the other covariates, the multivariate logistic regression analysis showed that the significant related factors of hyperuricemia were hypercholesterolemia, hypertriglyceridemia, and renal function impairment.


CONCLUSIONS
Hyperuricemia is often found in the elderly. Hyperuricemia is more common in elderly men than in elderly women. A large-scale investigation will be suggested in the future to address causal-effect issues between hyperuricemia and hypercholesterolemia, hypertriglyceridemia, or renalfunction impairment.
