Feasibility of using the Fitbit ? Charge HR in validating self-reported exercise diaries in a community setting in patients with heart failure

摘要

Background: Use of wrist-worn activity monitors has increased over the past few years; however, the use of the Fitbit? Charge HR (FCHR) in a community setting in patients with heart failure has not been tested. Purpose: The purpose of the study was to assess the feasibility, practicality and acceptability of utilizing the FCHR to validate self-reported exercise diaries and monitor exercise in community dwelling patients with heart failure. Methods: Thirty heart failure patients (12 females and 18 males) aged 64.7 ± 11.5 years were provided with a FCHR. Participants were provided with an exercise routine and for eight weeks, recorded their exercise sessions in self-reported exercise diaries and used the FCHR to record those exercise sessions. Results: Exercise data from the self-reported exercise diaries were validated with data from the FCHR. Participants’ perception and acceptance of using the FCHR was positive. Validation of exercise and physical activity interventions using the FCHR appears feasible and acceptable in patients with heart failure. Conclusion: Wrist-worn activity monitors can be useful for objective measurement of exercise adherence and monitoring of physical activity in patients with heart failure in a community setting.
