Abstract

Introduction: Approximately 7.7 percent of adults over the age of 65 have asthma in the United States (U.S), further, the population of older adults in the U.S. will increase to 20% by 2030. Health Related Quality of Life is low for this age group and asthma is often misdiagnosed and undertreated creating a need for research to improve factors that influence Asthma Quality of Life. Aims: This study explored two aims. The first aim evaluates the relationship between medication numeracy and asthma self-management knowledge with asthma self-efficacy. The second aim evaluates medication numeracy, asthma self-management knowledge, asthma self-efficacy, and asthma control with asthma quality of life. Methods: A secondary analysis was derived from the completed study entitled, “Asthma in Older Adults: Identifying Phenotypes and Factors Impacting Outcomes,” and was completed to identify factors affecting quality of life in older adults with asthma. Descriptive statistics, Pearson correlation coefficients, and regression analysis were used to explore these factors. Variables were chosen with guidance from the literature and the Wilson and Cleary Health Related Quality of Life Theory. Results: After completed analysis, the data showed that the regression model for Aim one was not significant and the variables of Asthma Self-Management Knowledge and medication numeracy did not have a significant relationship with asthma self-efficacy. For Aim two regression model showed significant relationships of age, number of comorbidities, medication numeracy and subjective asthma control with asthma quality of life. Conclusions: A new model of Asthma Quality of Life based on Wilson and Cleary’s Health Related Quality of Life model was proposed that included the variables that were found to be significant predictors of Asthma Quality of Life.
