Résumé
<p><b>OBJECTIVE</b>To explore the relationship between metabolic syndrome and chronic kidney disease (CKD) in a rural adult population of Hunan province.</p><p><b>METHODS</b>1953 residents (older than 18 years) from the same village were randomly selected, using a stratified, multistage sampling method. All residents were interviewed and tested for albuminuria with morning spot urine albumin to creatinine ratio (abnormal: >/= 30 mg/g), reduced renal function with estimated glomerular filtration rate by modified MDRD equation [abnormal: < 60 ml/min (1.73 m(2))]. The associations of kidney damage indicators with demographic characteristics (age, gender, smoking status), indicators on health (diabetes, hypertension) and metabolic syndrome traits were examined.</p><p><b>RESULTS</b>Eligible data of 1709 subjects were enrolled in the study. After the adjustment of age, gender and other metabolic syndrome traits, participants with metabolic syndrome had a higher prevalence of CKD (19.3% vs. 13.2%, P < 0.001) than those without the syndrome. As the number of metabolic syndrome traits increased, so did the prevalence of CKD. There seemed to be a strong and independent association between metabolic syndrome and chronic kidney disease. For participants without hypertension and diabetes, metabolic syndrome was also associated with CKD (OR value 1.733, 95%CI: 1.20 - 2.41, P = 0.004).</p><p><b>CONCLUSION</b>In these 1709 adults under this study from a village of southern China, metabolic syndrome seemed to be associated with CKD.</p>
