title: Association of Microalbuminuria with Metabolic Syndrome among Aged Population.
abstract: Background. The impact of the various components of metabolic syndrome (MetS) on chronic kidney disease has been conflicting. We aim to investigate the association between MetS and microalbuminuria and identify the major contributing components of MetS that result in microalbuminuria in the Chinese aged population. Methods. A total of 674 adults aged 55-98 years (males: 266; mean age: 66.5 ± 7.5 years) were studied. MetS was defined by the 2004 Chinese Diabetes Society criteria and microalbuminuria by urine albumin-creatinine ratio (UACR) ≥3 mg/mmoL. Results. The prevalence of microalbuminuria was gradually increased with increasing number of MetS components (P < 0.05). In multivariate regression, after adjusting for age and sex, MetS was the strongest correlate of microalbuminuria (OR = 1.781, 95% CI = 1.226-2.587; P < 0.05) followed by the fasting plasma glucose (FPG) (OR = 1.217, 95% CI = 1.044-1.092; P < 0.05), systolic blood pressure (SBP) (OR = 1.011, 95% CI = 1.107-1.338; P < 0.05), and high-density lipoprotein cholesterol (HDL-C) (OR = 0.576, 95% CI = 0.348-0.953; P < 0.05). Conclusions. MetS is independently associated with microalbuminuria in the Chinese aged population. Elevated FPG is the most predominant component of metabolic syndrome associated with microalbuminuria followed by elevated SBP and reduced HDL-C.
