Objective: Early prevention of renal dysfunction progression and cardiovascular disease is important in diabetes. We aimed to determine the risk factors for renal dysfunction and cardiovascular disease among medical insurance subscribers between 40 and 74 years of age in Japan.
Methods: This retrospective study involved 1585 subjects, including 97 patients with diabetes, who had undergone a specific health checkup in 2013 and 2019. The primary composite outcome included decline in estimated glomerular filtration rate (eGFR) by ≥30%, increase in urine albumin-to-creatinine ratio (UACR) by ≥30 mg/gCre, and increase in the Framingham Risk Score by ≥5%. We categorized the subjects into groups with and without these outcomes. Univariate analysis was conducted using Welch’s t-test, Pearson’s correlation coefficient, and Fisher’s exact test. Based on the univariate analysis, principle component and logistic analyses were performed to determine the predictive risk factors.
Results: Significant between-group differences were noted in terms of age, BMI, waist circumference, blood pressure, hemoglobin, hematocrit, triglyceride, HDL-C, LDL-C, AST, ALT, γ-GTP, HbA1c, serum creatinine, eGFR, urine creatinine, UACR, urine protein-to-creatinine ratio, sex, antihypertensive medication, history of anemia, diabetes, smoking, alcohol consumption, weight change, exercise habits, the will to improve and others. Logistic analysis showed that age (odds ratio [95% confidence interval]: 1.04 [1.02-1.06], P <0.0001), HDL-C (0.97 [0.96-0.98], P <0.0001), HbA1c (1.35 [1.12 -1.63], P =0.0015), and male sex (3.90 [2.97-5.11], P <0.0001) were predictive risk factors.
Conclusion: Lower HDL-C and higher HbA1c were detected as the risk factors for patients with diabetes and without diabetes. The results of this study indicate that the harmful effects of hyperglycemia and dyslipidemia may have started before the patients actively exhibit metabolic disorders.
