中国成年人血清尿酸与高血压前期的关系

目的 探讨中国成年人中血清尿酸水平与高血压前期的关系,评估年龄、肥胖、空腹血糖(FPG)和脂类对其影响.方法 对14 451例非高血压者的血压、BMI、FPG、血脂、血尿酸水平进行分析.结果 将血清尿酸水平按五分位法进行分层,校正相关因素后高血压前期风险的OR值随尿酸水平升高而升高.血清尿酸水平200～380 μmol/L,与高血压前期风险呈线性相关,200 μmol/L为这种线性相关的转折点,FPG可影响两者的相关性(P＜0.0001).结论 血清尿酸水平与高血压前期相关联,并独立于其他代谢危险因素.这种关联性在年长个体中差异无统计学意义.FPG可影响这种相关性.

Serum uric acid and prehypertension among Chinese adults

Objective The aim of this article is to discuss the relation between serum uric acid and prehypertension, and to evaluate the influence of age, obesity, fasting plasma glucose (FPG) and lipids in Chinese adults. Methods All the 14 451 non-hypertensive samples were analyzed for blood pressure, body mass index (BMI), FPG, lipids and serum uric acid. Results The serum uric acid levels were stratified by quintiles, after adjustment for relevant factors, OR values of prehypertcnsion increased with the elevated uric acid levels. Serum uric acid level was 200-380 μmol/L, it had a linear relationship with the risk of prehypertension, 200 μmol/L as a turning point for this linear relationship, FPG could affect their correlation (P ＜ 0.0001 ). Conclusions Serum uric acid was associated with prehypertension, independent of metabolic risk factors. The associations were not significant in old individuals. FPG may modify the associations.
