  • Lifestyle behaviors associated with the initiation of renal replacement therapy in Japanese patients with chronic kidney disease: a retrospective cohort study using a claims database linked with specific health checkup results

    Hara A., Hirata T., Okamura T., Kimura S., Urushihara H.

    Environmental Health and Preventive Medicine (Environmental Health and Preventive Medicine)  26 ( 1 ) 102 2021.12

    Research paper (scientific journal),  ISSN  1342078X

     View Summary

    Background: Chronic kidney disease (CKD) is an independent risk factor for progression to an end-stage renal disease requiring dialysis or kidney transplantation. We investigated the association of lifestyle behaviors with the initiation of renal replacement therapy (RRT) among CKD patients using an employment-based health insurance claims database linked with specific health checkup (SHC) data. Methods: This retrospective cohort study included 149,620 CKD patients aged 40–74 years who underwent a SHC between April 2008 and March 2016. CKD patients were identified using ICD-10 diagnostic codes and SHC results. We investigated lifestyle behaviors recorded at SHC. Initiation of RRT was defined by medical procedure claims. Lifestyle behaviors related to the initiation of RRT were identified using a Cox proportional hazards regression model with recency-weighted cumulative exposure as a time-dependent covariate. Results: During 384,042 patient-years of follow-up by the end of March 2016, 295 dialysis and no kidney transplantation cases were identified. Current smoking (hazard ratio: 1.87, 95% confidence interval, 1.04─3.36), skipping breakfast (4.80, 1.98─11.62), and taking sufficient rest along with sleep (2.09, 1.14─3.85) were associated with the initiation of RRT. Conclusions: Among CKD patients, the lifestyle behaviors of smoking, skipping breakfast, and sufficient rest along with sleep were independently associated with the initiation of RRT. Our study strengthens the importance of monitoring lifestyle behaviors to delay the progression of mild CKD to RRT in the Japanese working generation. A substantial portion of subjects had missing data for eGFR and drinking frequency, warranting verification of these results in prospective studies.

    Incorrect Since CVD risk increases with age, categories for age were based on 10-year intervals up to age 60 years and 5-year intervals thereafter. Diabetes mellitus (DM) is defined as having a fasting blood glucose level of ≥ 126 mg/dL, currently using anti-diabetic medication, or both. Cigarette smoking was dichotomized as current versus other. Low-density lipoprotein cholesterol (LDL-C) was calculated using the Friedewald equation . Non-HDL-C was calculated by subtracting HDL-C from TG. If the TG level was greater than 400 mg/dL, we set the value as missing (n =96).
