Background
Cardiovascular disease is major cause of mortality among chronic kidney disease (CKD) patients, and it is fundamental to focus on reducing the potential risk factors. Regular physical activity is known to reduce the risk of cardiovascular disease in general population. However, whether the change of physical activity habits is beneficial for pre-dialysis CKD patients had not been examined thoroughly.
Methods
We performed a nationwide population based cohort study using the database of Korean National Health Insurance System. Among adult patients who received national health screening program ≥2 times between 2012 and 2016, CKD patients were identified using the serum creatinine and dipstick albuminuria measurements. Those who previously underwent dialysis or diagnosed cardiovascular disease were excluded. The frequency and the intensity of the physical activity were obtained at least twice, from self-reported questionnaire during the health examination. The study groups were divided according to the status of physical activity habit alteration; active, quit exercise, start exercise, and inactive group. Then, the development of myocardial infarction (MI), stroke or death was assessed using the multivariate Cox regression analysis.
Results
During the median follow up of 3.18 years, 549,187 CKD patients were examined for adverse outcomes. Compared to those who remained inactive, the active group patients who consistently continued physical activity exhibited lower risk of MI (hazard ratio (HR); 0.76, 95% confidence interval (95% CI); 0.69-0.85), stroke (HR (95%CI) 0.69 (0.62-0.78)), and death (HR (95%CI) 0.62 (0.57-0.67)). Moreover, those who newly started physical activity also showed lower risk of adverse outcomes, compared to the inactive group (HR (95%CI) 0.83 (0.76-0.89)).
Conclusion
Continuation of physical activity in pre-dialysis CKD patients is beneficial to reduce the risk of cardiovascular disease development. Therefore, clinicians should encourage even mild intensity of physical activity to CKD patients.
