The prevalence of hyperuricemia is low in Uygurs, who have a high prevalence of cardiovascular risk factors such as hypertension, overweight-obesity, dyslipidemia, hyperglycemia, and insulin resistance (IR). This study sought to investigate the relationships between serum uric acid (UA) and these risk factors in this population. A cross-sectional study was conducted in Uygurs (859 males, 1268 females) aged 20 to 70 years. Demographic data, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), and fasting and postprandial blood were obtained, and biological measurements were determined. The mean of BMI, SBP, DBP, total cholesterol, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides, fasting blood glucose, fasting insulin, and homeostasis model assessment insulin resistance index (HOMA-IR), and the prevalence of hypertension, IR, hyperglycemia, overweight-obesity, hypercholesteremia, hyper-LDL-c, and hypertriglyceridemia increased with UA but the prevalence of hypo-HDL-c decreased (p < 0.05). Logistic regression analysis showed that the odds ratios for IR, overweight-obesity, hypercholesteremia, hyper-LDL-c, and hypertriglyceridemia against the lowest UA group increased but decreased for hypo-HDL-c (p < 0.05). The UA in the hypo-HDL-c group was lower than that of the controls; the prevalence of hypo-HDL-c in hyperuricemia subjects was lower than in those with normal UA (p < 0.05). But the opposite results were observed between overweight-obesity, hyperglycemia, IR, hypercholesteremia, hypertriglyceridemia, and hyper-LDL-c and correspondence controls, respectively (p < 0.05). In Uygur, elevated UA is associated with overweight-obesity, hypercholesteremia, hyper-LDL-c, hypertriglyceridemia, hyperglycemia, and IR. The HDL-c level significantly increases with UA, whereas the prevalence of hypo-HDL-c decreases. Further studies are needed to clarify why UA is positively correlated to HDL-c.
维吾尔族人群中高尿酸血症的患病率较低,但高血压、超重肥胖、血脂异常、高血糖和胰岛素抵抗(IR)等心血管危险因素的患病率较高。本研究旨在探讨该人群血尿酸(UA)与这些危险因素之间的关系。采用横断面研究方法,纳入年龄在 20 至 70 岁的维吾尔族人群(男性 859 人,女性 1268 人)。收集人口统计学数据、收缩压(SBP)、舒张压(DBP)、体重指数(BMI)和空腹及餐后血糖,并进行生物学指标检测。结果显示,BMI、SBP、DBP、总胆固醇、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c)、甘油三酯、空腹血糖、空腹胰岛素和稳态模型评估的胰岛素抵抗指数(HOMA-IR)的平均值,以及高血压、IR、高血糖、超重肥胖、高胆固醇血症、高 LDL-c 和高三酰甘油血症的患病率随着 UA 的增加而升高,而低 HDL-c 的患病率则降低(p<0.05)。Logistic 回归分析显示,IR、超重肥胖、高胆固醇血症、高 LDL-c 和高三酰甘油血症的 OR 值随着 UA 最低组的升高而增加,而低 HDL-c 的 OR 值则降低(p<0.05)。低 HDL-c 组的 UA 低于对照组;高尿酸血症患者的低 HDL-c 患病率低于正常 UA 患者(p<0.05)。但超重肥胖、高血糖、IR、高胆固醇血症、高三酰甘油血症和高 LDL-c 与相应对照组之间的结果相反(p<0.05)。在维吾尔族人群中,UA 升高与超重肥胖、高胆固醇血症、高 LDL-c、高三酰甘油血症、高血糖和 IR 有关。UA 水平随着 HDL-c 的升高而显著升高,而低 HDL-c 的患病率则降低。需要进一步研究来阐明为什么 UA 与 HDL-c 呈正相关。
