Metabolic syndrome and its components associated with glomerular filtration rate in middle-aged and elderly population / 中华内分泌代谢杂志

ABSTRACT

Objective To explore the relationship between metabolic syndrome(MS) and glomerular filtration rate(GFR).Methods A total of 10 140 adults aged 40 years and older inhabitants in Zhaiji community of Guiyang urban areas were investigated from May 2010 to August 2010 by adopting stratified cluster sampling method.The venous blood sample was drawn for the measurements of serum creatinine(Cr), fasting plasma glucose(FPG), OGTT 2hPG, fasting insulin, triglyceride(TG), total cholesterol(TC), high-density lipoprotein-cholesterol(HDL-C), low-density lipoprotein-cholesterol(LDL-C), and fasting plasma insulin.The definition of MS in our study was modeled after the Adult Treatment Panel Ⅲ(ATP-Ⅲ).Decreased GFR was defined as an estimated GFR<60 ml·min-1·(1.73 m2)-1.Results The prevalence of GFR less than 60 ml·min-1·(1.73 m2)-1 were 3.0% and 1.2% in participants with and without MS, respectively.The multivariate-adjusted odds ratios[95% confidence interval(CI)] of MS, which were independently associated with decreased GFR, were with elevated blood pressure, higher TG, lower HDL-C, and elevated FPG, their statistically odds ratios were 1.78, 2.96, 1.06, and 1.22, respectively.The prevalence of GFR decreased with the increase of MS components by 0.56%, 1.10%, 1.50%, 2.87%, 3.23%, and the odds ratios were 1.00, 1.57, 1.93, 3.07, and 2.89, respectively.Conclusion With the increase of MS components the risk of GFR decline increased.The occurrence of chronic renal dysfunction(CKD) might integrate multiple different risk factors of MS.
