Abstract

The prevalence of renal insufficiency in hypertensive participants without comorbidities affecting renal function is unknown. The objective of this study was to assess the prevalence and predictors of renal insufficiency in general hypertensive population. We examined 994 hypertensive participants aged 45-70 years without previously diagnosed diabetes, cardiovascular disease or chronic kidney disease. Renal insufficiency was defined as estimated glomerular filtration rate <60 ml min(-1) per 1.73 m(2) by the Modification of Diet in Renal Disease formula. The metabolic syndrome was defined according to the International Diabetes Federation and the US National Cholesterol Education Program Third Adult Treatment Panel criteria. Glucose homoeostasis was assessed with an oral glucose tolerance test. The prevalence of renal insufficiency was 6.7% (95% confidence interval (CI) 5.3-8.5). In a multivariate model, the presence of renal insufficiency was predicted by female gender (odds ratio (OR) 3.57 (95% CI 1.90-6.72)), older age (OR 1.13 (95% CI 1.07-1.18)), use of diuretics (OR 2.13 (95% CI 1.19-3.82)) and metabolic syndrome (OR 2.79 (95% CI 1.34-5.79)). Newly diagnosed diabetes or prediabetes did not predict renal insufficiency. The prevalence of renal insufficiency was found to be lower than previously reported in hypertensive general population. Metabolic syndrome, but not newly diagnosed diabetes or prediabetes per se, was strongly associated with renal insufficiency especially in women. Renal insufficiency was also associated with the use of diuretics, but the clinical relevance of this finding needs to be clarified.
