Background:Decreased glomerular filtration rate (GFR) was associated with increased mortality and decreased quality of life in previous studies. In Korean adults, the prevalence rates of cardiometabolic risk factors are higher in women than in men after middle age. We evaluated the association between cardiometabolic risk factors and decreased GFR in Korean women.

Methods:We evaluated 2,339 subjects using data from the Korea National Health and Nutrition Examination Survey VII-1 (2016) after excluding participants with GFRs of <15 mL/min/1.73 m2. Normal GFR was ≥60 mL/min/1.73 m2, and decreased GFR was 15–59 mL/min/1.73 m2. Socioeconomic status, lifestyle factors, body mass index, waist circumference, and comorbidities were evaluated to analyze the association between cardiometabolic risk factors and decreased GFR. The odds ratio (OR) and 95% confidence interval (CI) were calculated using multivariate logistic regression analyses.

Results:As age increased, the OR for decreased GFR increased. In comparison with women with waist circumferences of <85 cm, the women with waist circumferences of ≥85 cm (OR, 1.94; 95% CI, 1.22–3.10) had a significant increase in the OR for decreased GFR. In women with diabetes mellitus, the OR for decreased GFR significantly increased (OR, 3.14; 95% CI, 1.70–5.81).

Conclusion:Decreased GFR was associated with age, abdominal obesity, and diabetes mellitus in Korean women. Control of abdominal obesity and appropriate management of diabetes mellitus are needed to prevent chronic kidney disease in Korean women.
