摘要
Background and aims: In previous studies, Pro12Ala polymorphism in peroxisome proliferator-activated receptors gamma 2 (PPAR-gamma 2) was shown to be associated with both longevity and metabolic syndrome, which was closely related with hyperuricemia. We examined long-lived subjects (>= 90 years), to ascertain whether the polymorphism is associated with the level of serum uric acid (SUA). Methods: The present study analysed data from a survey conducted in 2005 on all residents aged 90 years or more in a district with 2,311,709 inhabitants. Results: The sample comprised 669 unrelated Chinese participants (aged 90-108 years, mean: 93.54 +/- 3.53 years; 67.2% women). The genotype frequencies of the Pro12Ala polymorphism were 0% Ala12Ala and 9.0% Pro12Ala, 91.0% Pro12Pro. Between men or women, and between subjects who were or were not 12Ala carriers, neither in SUA levels nor the prevalence of hyperuricemia were significant. Between subjects with and without hyperuricemia, the difference in prevalence of 12Ala carriers was also non-significant. Unadjusted and adjusted multiple logistic regressions showed that the odds ratios (OR) for hyperuricemia were not associated with Pro12Ala polymorphism in PPAR-gamma 2. Conclusions: In Chinese nonagenarians and centenarians, SUA levels are not associated with polymorphism in PPAR-gamma 2.
