山东沿海居民血尿酸水平与心血管疾病危险因素的关系

目的 探讨山东沿海地区居民的血清尿酸水平与心血管疾病危险因素之间的相关性.方法 实验设计采用随机整群抽样分层设计的方法 ,调查研究了4 988名山东沿海地区居民一般生活、健康及营养状况,采用白动生化分析仪和电化学发光分析仪检测受试者的空腹血尿酸、血脂、胰岛素等指标.结果 在男女受试者中,其心血管危险因索如收缩压、舒张压、肌酐、总胆固醇(TC)、甘油三酯(TG)、腰围以及体重指数(BMI)都随着血清尿酸值的升高而增加,而高密度脂蛋白胆固醇水平逐级降低.女性受试者的稳态模型评估的胰岛素抵抗指数(HOMA.IR)逐级升高,而男性受试者的升高不明显.与血尿酸<280μmol/L组相比.血尿酸280～319、320～349 >1350 μmol/L 3组女性受试者发生高血压的相对危险度(DR)分别为1.54、1.88和2.70,而发生代谢综合征(MS)的OR分别为2.29、4.15和4.96;在男性,与血尿酸<280μmoL/L组相比,血尿酸320～379、380～419和≥420 μmol/L 3组受试者发生MS的OR分别为I.41、1.87和3.27,血尿酸/>420 μmol/L组发生高血压的OR为1.52.调整混杂因素后,Logistic回归分析显示,在男性和女性巾高尿酸均可视为高血压的独立危险因素.结论 较高的血清尿酸水平与心血管疾病的发生和发展密切相关,在临床实践中应予重视.

Correlation between serum uric acid and cardiovascular risk factors in Shandong coastal inhabitants

Objective To elucidate the relationship between serum uric acid (SUA) and cardiovascular risk factors in Shandong coastal inhabitants. Methods A random, stratified cluster sampling method was conducted. A population.based cross-sectional survey for hyperuricemia was performed and 4 988 dwellers of Shandong coast were investigated. Fasting SUA,lipid profiles,insulin concentrations,etc.,were determined by automatic biochemical analysis device and electrochemiluminescence analyzer.The investigation of general,healthy and nutritional conditions was carried out by questionnaire. Results In male and female subjects, the cardiovascular risk factors such as systolic blood pressure,diastolic blood pressure, selum ereatinine,total cholesterol.triglvceride,waist circumference and body mass index all increased with rising SUA,and the level of senlm high densitv lipoprotein fell accordingly.Homeostasis model assessment insulin resistance index (HOMA- IR) in female subjects increased by the quartile group,not in male subjects.Compared with SUA<280 μmol/L group.odds ratio(OR) values of hypertension in SUA 280-319,320-349,≥350 μmol/L groups were 1.54,1.88 and 2.70 respectively in female,and 2.29,4.15 and 4.96 for metabolic syndrome (MS).As for male,compared with SUA<280 μmol/L group OR value of hypertension in SUA ≥420 μmol/L group was 1.52,and OR values of MS of 1.41,1.87 and 3.27 occurred in SUA 320～379,380～419,≥420 μmol/L groups.After being adjusted for confounding factors,logistic stepwise regression revealed that elevated SUA was an independent risk factor for hypertension in both genders.Conclusion Elevated SUA level is closely related to the incidence and development of cardiovascular diseases,and should not be ignored in clinical practice.
