Current status of exercise and its impact on quality of life in patients undergoing peritoneal dialysis in the post-COVID-19 period.

Clinical Nephrology 2023 October 6
OBJECTIVES: The aims of this study were to investigate the current status and the influence factors of exercise, and to explore the impact of exercise on the quality of life (QoL) in peritoneal dialysis (PD) patients in the post-COVID-19 period.

MATERIALS AND METHODS: Those PD patients who were followed up between September 2020 and August 2021 were enrolled. The collected data included demographic information, clinical data, exercise data, and QoL.

RESULTS: In total, 339 PD patients were included in this cross-sectional study. The mean age was 44.0 ± 13.0 years, with a median PD duration of 6.7 (1.7 - 41.9) months. The primary renal disease was glomerulonephritis (68.4%). 277 (81.7%) PD patients performed exercise, with median exercise time 5.0 (3.5 - 7.8) hours per week. The main type of exercise was slow walking. Pain (odds ratio (OR) = 0.311, p = 0.002) and lower hemoglobin level (OR = 1.016, p = 0.033) were independent risk factors for exercise. Moreover, male sex (B = 2.803, p < 0.001) was an independent protective factor, while advanced age (B = -0.097, p < 0.001), higher body mass index (B = -0.154, p < 0.001), and pain (B = -0.643, p = 0.023) were independent risk factors for exercise intensity. After adjustment for other confounders, exercise (B = 5.787, p = 0.037) was an independent protective factor for total score of QoL in PD patients.

CONCLUSION: In the current study, 81.7% of PD patients performed exercise in the post-COVID-19 period. Pain and anemia were independent risk factors for exercise in PD patients. Advanced age, female sex, higher body mass index, and pain were independently associated with lower exercise capacity in PD patients. PD patients undergoing exercise had better QoL.
