Objective. The purpose of the study was to determine the distribution of estimated glomerular filtration rate (eGFR) values among the Japanese working generation using representative health checkup data. Design. Cross-sectional, observational, large cohort study Setting. Japan Health Insurance Association, Tokyo Branch Participants. Data for 766,556 participants aged 35-74 years who attended preventative health checkup for lifestyle-related disease conducted by the Japan Health Insurance Association, Tokyo Branch, in 2012 were included. After excluding dialysis patients and those with missing data, 766,095 participants (mean age, 48.9 years; 68.1% male) were selected for analysis. Main outcome measures. Serum creatinine-based eGFR values were analyzed in 5-year age groups. Results. The age-specific mean eGFR values were 86.4, 83.0, 79.8, 77.4, 75.5, 73.2, 70.9, and 67.8 mL/min/1.73 m2 for the age groups of 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-69, and 70-74 years, respectively. The difference in eGFR per 1-year difference in age was 0.523 mL/min/1.73 m2/year. The mean eGFR was higher in the female participants for all age groups, being most apparent in those aged 35-50 and 60-74 years. However, without body surface-area correction, the mean eGFR was lower in the female participants for all age groups. Conclusion We described the distribution of eGFR values on the basis of a large data set obtained during health checkup examinations in Japan. We found these data to be representative of the 35-74 year-old Japanese general population.
