[Association between hypertriglyceridemic waist?to?height ratio phenotype and chronic kidney disease in a community population in South China: a cross-sectional study].

OBJECTIVE: To investigate the relationship between hypertriglyceridemic waist to height ratio phenotype (HWHtR) and chronic kidney disease (CKD) in a community population in South China. METHODS: A cross sectional study was conducted among 2142 residents in Zhuhai (Guangdong Province, China) from June to October of 2012. The HWHtR phenotype was defined as a waist to height ratio(WHtR) ≥0.55 and triglyceride level ≥2.0 mmol/L, based on which the participants were divided into HWHtR group and nonHWHtR group. CKD was defined as an eGFR<60 mL/min per 1.73 m2 or an ACR ≥30 mg/g. A logistic regression model was established to investigate the relationship between chronic kidney disease and HWHtR phenotype. RESULTS: Compared with the nonHWHtR group, the HWHtR group had a higher prevalence of chronic kidney disease (11.1% vs 33%, P<0.001). Analysis using the logistic regression model showed that HWHtR was significantly associated with CKD in the unadjusted analyses (OR=3.23, 95% CI: 2.32-4.48, P<0.001). After adjustment for age, sex, history of hypertension, history of diabetes, systolic blood pressure, diastolic blood pressure, drinking, physical exercise, education and current smoking, HWHtR was significantly associated with CKD (OR=2.36, 95% CI: 1.52-3.67, P<0.001); the association of HWHtR and CKD was still significant after further adjustment for BMI (OR=2.12, 95%CI: 1.34-3.35, P<0.001). CONCLUSION: Our finding suggests that HWHtR is associated with CKD in this community population.
