Abstract [en]

Purpose: Depressive symptoms have been shown to directly influence perceived health among persons with heart failure (HF). Decreased physical activity and appetite may also be predictive of poor perceived health.The purposes of this study were to determine whether appetite and physical activity predicted perceived health, and to determine whether depressive symptoms mediated or moderated their relationship with perceived health.

Methods: A total of 184 patients with mild to severe HF were included. Appetite, depressive symptoms and perceived health were measured by self-report questionnaires (Council on Nutrition Appetite Questionnaire, Patient Health Questionnaire and EuroQol 5D index). Physical activity was measured by SenceWearTM for 6 days. A separate series of multiple linear regression analyses were run to determine whether depressive symptoms mediated or moderated the relationship between physical activity and perceived health, and between appetite and perceived health.

Results: Higher physical activity predicted better perceived health (ß=0.202, p=.006) but the strength of the association decreased (ß=0.13, p=.048) when depressive symptoms were included in the model. There was a significant mediation effect for depressive symptoms on perceived health (sobel=2.03, p=.041) (Fig 1). Appetite was a significant predictor of perceived health. Examination of this association among those with and without depressive symptoms, however showed positive association between appetite and perceived health remained only for patients without depressive symptoms demonstrating a moderating effect (p<.001) (Fig 2).

Conclusion: Identifying and treating depression simultaneously while addressing appetite and physical activity may be key to improving perceived health among persons with HF.
