Physical Activity and Sedentary Time among Kidney Transplant Recipients: Associations with Health-Related Quality of Life and Psychosocial Health

Abstract

Objective: The primary objective of this thesis was to determine associations of health-related quality of life (HRQoL) and psychosocial factors (i.e., self-esteem, depression, psychological growth) with objectively-assessed walking (i.e., pedometers), self-reported physical activity, and sedentary time among kidney transplant recipients. Methods: Adults across Canada, living with a kidney transplant were recruited using research advertisements placed in kidney transplant-related media. Interested individuals were sent a survey package containing a health-related questionnaire, step pedometer, and a self-addressed business reply envelope Results: A total of 32 kidney transplant recipients returned a completed survey, for a response rate of 82.1% (32 out of 39). The total average steps per day were 9751.8 steps (SD = 3685.1). Overall, 59% were achieving public health physical activity guidelines. The total average sitting time during the week was 11.6 hours per day while total average sitting time during the weekend was 8.9 hours per day. Compared to those not achieving at least 10,000 steps per day, those who were achieving at least 10,000 steps per day had a significantly higher physical component score for HRQoL (Mdiff = 7.8, p = .018), and fewer depressive symptoms (Mdiff = 3.7, p = .031). Similar patterns emerged for meeting physical activity guidelines and sitting time. Conclusion: For kidney transplant recipients, greater participation in walking, overall physical activity, and lower engagement in sedentary activity, was associated with better HRQoL and fewer depressive symptoms.
