ABSTRACT
INTRODUCTION: The purpose was to make longitudinal measurements of physical activity and study whether physical activity decreases over time in maintenance hemodialysis (MHD) patients.
METHODS: This was an observational study, where MHD patients were considered in a 12-month follow-up. Laboratory variables and physical activity were tested three times over 12-months in 124 hemodialysis patients. Physical activity was measured using the Human Activity Profile (HAP), the Stanford 7-day Physical Activity Recall Questionnaire (PAR), and walking speed. Repeated measure variance analysis was used to analyze changes of physical activity. The Bonferroni method was used to do pairwise comparisons.
FINDINGS: The proportion of decreased physical activity increased (P < 0.05). The maximal activity score (MAS), adjusted activity score (AAS), HAP dimension scores, and walking speed all decreased at the three time points studied (P < 0.001). At the same time, moderate physical activities and PAR values changed at three time points (P < 0.05). Pairwise comparisons showed that between the baseline and the 6-month follow-up, MAS, AAS, the scores of personal/household work, entertainment/social, independent exercise, leg effort, and back effort, all decreased(P < 0.05). Between the baseline and the 12-month follow-up, and between the 6-month follow-up and the 12-month follow-up, all the scores of HAP and walking speed decreased significantly (P < 0.001). Between the baseline and the 6-month follow-up, moderate physical activities and PAR values increased (P < 0.05). However, between the baseline and the 12-month follow-up, and between the 6-month follow-up and the 12-month follow-up, moderate physical activities and PAR did not change statistically.
CONCLUSION: Physical activity decreased in hemodialysis patients in the 12-month follow-up.
