Abstract 11412: Predictors of Overall Perceived Health in Patients with Heart Failure
INTRODUCTION: Overall perceived health (OPH) is a powerful and independent predictor of negative health outcomes and low health-related quality of life. For reasons unknown, OPH is conspicuously low in patients with heart failure (HF).
OBJECTIVE: The purpose of this study was to determine the key variables associated with OPH in persons with HF and to evaluate the variability in OPH attributable to each.
METHODS: This cross-sectional predictive correlational study was a secondary analysis of an existing dataset. Individual characteristics, biophysiological variables, physical symptoms, psychological symptoms, and physical and social functioning were included as predictor variables in a five-step hierarchical regression analysis.
RESULTS: The sample (n=265) was primarily male (64.2%), white (61.9%), with a mean age of 62 years, at least a high school education, and a household income enough or more than enough to meet needs. Most (69.1%) had systolic dysfunction, and 78.5% were NYHA III or IV. Individual characteristics explained 20.5% of the variance in OPH. The final model containing 15 predictors explained 39.2% of the variance in OPH. Six variables were significant independent predictors of OPH: income, social functioning, comorbid burden, symptom stability, race, and the interaction of gender and social functioning, the later indicating social functioning was a stronger predictor for males than for females. In a multiple mediation analysis, the effects of shortness of breath and fatigue on OPH were mediated by physical and social functioning. Gender moderated the mediation of fatigue by social functioning.
CONCLUSIONS: These variables explained a significant portion of the variance in OPH and can be used to target individuals at risk for low OPH and tailor interventions. If OPH decreases or is low, a focus on patient symptoms and ability to participate in life activities is appropriate, with particular attention to social functioning in men.
