Why the study?
Physical activity is essential in chronic heart failure, but longitudinal changes and associated factors during the post-discharge transition period require greater understanding to help create interventions.
Physical activity in chronic heart failure patients drops to its lowest level two weeks post-discharge, and this decline is significantly mediated by CHF-related symptoms and kinesiophobia.
Symptom increases at 2 weeks post-discharge associate with PA decline in CHF; hypothesis-generating for targeted interventions.
Abstract Background Physical activity (PA) is essential and effective for chronic heart failure (CHF) patients. Greater understanding of the longitudinal changes in PA and its association factors during the post-discharge transition period may help create interventions for improving PA. The aims of this study are: 1) to compare the change of PA; 2) to examine the associated factors of PA change; 3) to verify the mediating pathways between the factors and PA during the post-discharge transition period in CHF patients. Methods A total of 209 CHF patients were recruited using a longitudinal study design. Structured questionnaires were used to assess PA, CHF-related symptoms, kinesiophobia, and demographics, disease characteristics. PA questionnaire was investigated: (1) during admission, (2) two weeks after discharge, (3) two months after discharge, and (4) three months after discharge. Additional three questionnaires were collected during admission. Generalized estimating equation models (GEE) were fitted to identify variables associated with PA over time. We followed STROBE checklist for reporting the study. Results PA of CHF patients decreased unevenly, with the lowest level at two weeks after discharge. CHF-related symptoms and kinesiophobia were significantly associated with PA change trend over time. Compared with before hospitalization, increase in CHF-related symptoms at two weeks and two months after discharge were significantly associated with a decrease in PA. In the path analysis, CHF-related symptoms related to PA not only directly but also indirectly through kinesiophobia. Conclusion PA was changed during the post-discharge transition period and associated with CHF-related symptoms and kinesiophobia in CHF patients. Improving kinesiophobia may help reduce CHF-related symptoms and improve PA.
