ABSTRACT
OBJECTIVE@#To explore the relationship between metabolic syndrome (MS) and the risk for chronic kidney disease (CKD) in premenopausal and postmenopausal women.@*METHODS@#We conducted a cross-sectional study among 1346 community-based women from June to October 2012 and collected the data of personal history, lifestyle, physical measures and laboratory indicators. The diagnosis of CKD was established for an eGFR of less than 60 mL/min per 1.73 m or albuminuria. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Guide. According to an epidemiological survey in Guangdong province, women older than 48.9 years were classified as having a postmenopausal status. The prevalence of MS and CKD was determined in both the premenopausal and postmenopausal women, and the association between MS and CKD was analyzed using logistic regression models.@*RESULTS@#MS was significantly correlated with CKD in premenopausal women in both unadjusted analyses (OR=3.10, 95% : 1.32-7.28, =0.009) and in analysis after adjustment for potential confounders (OR=4.09, 95% : 1.63- 10.32, =0.003). When adjusted for diabetes, hypertension, and hyperuricemia, no correlation was found between MS and CKD in premenopausal women (OR=1.56, 95% : 0.31-7.63, = 0.592); in the unadjusted analyses, MS was significantly correlated with CKD in postmenopausal women ( < 0.001). After further adjustment for age, education status, current smoking, physical inactivity, and current drinking, MS was still significantly correlated with CKD (OR=2.60, 95% : 1.69-3.99, < 0.001). When adjusted for diabetes, hypertension, and hyperuricemia, the correlation between MS and CKD was still significant (OR=1.61, 95% : 1.09-2.37, =0.018). In the unadjusted model, a high blood pressure (OR=2.77, 95%CI: 1.57-4.89, < 0.001), an elevated serum triglyceride level (OR=1.84, 95%: 1.16-2.90, =0.009) and a high fast glucose level (OR=2.07, 95%: 1.30-3.28, =0.002) were all significantly correlated with CKD in postmenopausal women. After adjusting for age, current smoking, current alcohol use, education status and physical inactivity, a high blood pressure (OR=2.28, 95%: 1.22-4.26, =0.01), a high serum triglyceride level (OR=1.71, 95%: 1.03-2.86, =0.039) and a high fast glucose (OR=2.25, 95%: 1.36-3.73, =0.002) were still significantly correlated with CKD in postmenopausal women. Blood pressure, serum triglyceride level, fast glucose, serum HDL cholesterol level and central obesity were not correlated with CKD in either the unadjusted model or adjusted model in premenopausal women ( > 0.05).@*CONCLUSIONS@#MS is correlated with CKD in both premenopausal and postmenopausal women, and the association is dependent on diabetes, hypertension, and hyperuricemia in premenopausal women but not in postmenopausal women.
