Association between the metabolic syndrome and chronic kidney disease in Chinese adults

Background. The metabolic syndrome is a common risk factor for cardiovascular and chronic kidney disease (CKD) in Western populations. We examined the relationship between the metabolic syndrome and risk of CKD in Chinese adults. Methods. A cross-sectional survey was conducted in a nationally representative sample of 15 160 Chinese adults aged 35–74 years. The metabolic syndrome was defined as the presence of three or more of the following risk factors: elevated blood pressure, low high density lipoprotein (HDL)-cholesterol, high triglycerides, elevated plasma glucose and abdominal obesity.
