title: Prevalence of chronic kidney disease in the Black Sea Region, Turkey, and investigation of the related factors with chronic kidney disease.
abstract: We aimed to assess the prevalence of CKD in the Black Sea Region, Turkey, and to evaluate any relationship between age, gender, diabetes, obesity, hypertension, and CKD. This study was conducted in 70 different areas in Tokat Province in the Black Sea Region, in the northern part of Turkey. The estimated glomerular filtration rate (eGFR) was calculated from the serum creatinine using MDRD formulas. CKD-defined estimated GFR was lower than 60 mL/min/1.73 m(2). A total of 1,079 persons were included in this study (mean age 41.4+/-17 years [range: 18-95 years], 49.4% males, 50.6% living in an urban area). Of the 1,079 individuals, 5.28% were diabetic, 22.9% were obese, and 37.8% were hypertensive. CKD was found in 62 of them (5.75%). The prevalence of CKD was 5.58% in non-diabetics and 8.77% in diabetics. No significant differences were found between two groups. The prevalence of CKD was 3.77% in non-hypertensive individuals and 8.82% in hypertensive patients, and 4.46% in non-obese and 9.31% in obese. The evident significant differences were found between groups (p < 0.0001 and p = 0.004, respectively). The prevalence of CKD increased with age within our population. A salient observation was the markedly higher prevalence of CKD in females than males (p = 0.046). There was an inverse correlation between eGFR and age (r = 0.529, p < 0.0001). The overall prevalence of CKD was 5.75% in general population. The prevalence of CKD increased with age within our population. Age, gender, obesity and hypertension were found to be significant risk factors for development of CKD in our population.
