摘  要:目的研究血肌酐正常的中老年人群血尿酸(UA)水平和早期肾功能损害的关系及其早期肾功能损害的患病率。方法对成都的社区自然人群按照随机抽样方法抽取样本,对血肌酐正常的1023人,平均年龄(63±6)岁;进行了相关心血管危险因素的调查,其中包括血肌酐和血UA水平。评价肾功能采用MDRD方程估算的肾小球滤过率(eGFR)。根据资料分析该人群早期肾功能损害[89≥eGFR≥60ml·min^-1·(1.73m^2)^-1]的患病率,并将人群按血UA水平四分位间距分为4组:UA〈282umol/L(A组)、282umol/L≤UA〈331umol/L(B组),331umol/L≤UA〈379umol/L(C组),UA≥379umol/L(D组),分析血UA水平与早期肾功能损害的关系。结果该组人群中早期肾功能损害的患病率为28.1%,其中男性的患病率为35.8%,女性为19.5%,差异有统计学意义(P〈0.01)。在男女两性中,血UA水平均和eGFR呈负相关,男性D组肾功能损害的患病率是A组的4.5倍(45.1%比10.6%),女性D组肾功能损害患病率为A组的3.8倍(38.7%比9.9%)。采用Logistic回归模型校正了性别,年龄,腰围,体质指数,甘油三酯,高密度酯蛋白胆固醇,总胆固醇,高血压病史及糖尿病病史等因素后,以A组为对照,早期肾功能损害的OR值B组为1.740(95%CI:0.817—3.706;P:0.151),C组为3.599(95%CI:1.742—7.433;P=0.01)及D组为5.488(95% CI:2.613—11.525;P〈0.01)。结论在血肌酐正常的中老年人群中,血UA水平和早期肾功能损害独立相关,男性早期肾功能损害的患病率高于女性。Objective To investigate the association between serum uric acid (UA) and early kidney damage and the prevalence of early kidney damage [ 89 ≥ GFR ≥60 ml · min^-1 (1.73m^2)^-1] in the middle-aged and elders with normal serum creatinine. Methods A survey of cardiovascular risk factors, including serum UA and estimated glomerular filtration rate (eGFR) [ according to MDRD ( modification of diet in renal disease) equation], was carried out in a local general population of Chengdu. A total of 1023 subjects with normal serum creatinine [mean age: (63 ±6) years; male: female =52. 7% : 47. 3% ] were recruited by random sampling method. The subjects were divided into 4 groups (A, B, C, D) according to the quartiles of serum UA levels (A: UA 〈282 umol/L, B: 282 umol/L±UA 〈331 umol/L, C: 331 umol/L±UA 〈379 umol/L, D:UA≥379umol/L). Results In the group, the prevalence of early kidney damage was 28. 1% (men: 35.8% 〉 women: 19. 5%, P 〈0. 01). In men and women, serum UA and mild kidney dysfunction were negatively correlated, and the prevalence of early kidney damage significantly increased with the elevated level of serum UA. The prevalence of early kidney damage was higher in men than women (P 〈 0. 01 ). According to the logistic regression analysis adjusting for age, gender, waist, body mass index, triglyceride, HDL-C, total cholesterol, history of hypertension and diabetes type 2, the odds ratio of the prevalence of early kidney damage were 1.0 [ B:I. 740 (P =0. 151 ), C:3.599 (P =0. 01 ) and D: 5. 488 (P 〈 0. 01 ) respectively ]. Conclusion In the middle-aged and elders with normal serum creatinine, serum UA and eGFR are negatively correlated. And serum UA level is independently associated with early kidney damage.
