OBJECTIVES: People with asthma can experience limitations in their daily activities. However, it is not apparent which personal characteristics are associated with such limitations. Therefore, the objective was to investigate the characteristics associated with having an activity of daily living limitation (ADLL) or instrumental activity of daily living limitation (IADLL) among United States (US) adults with asthma.
METHODS: This cross-sectional study included US adults with asthma in the Medical Expenditure Panel Survey full-year consolidated dataset. Two multivariable binomial logistic regression models were developed to investigate the characteristics associated with: (1) having an ADLL; and (2) having an IADLL. Characteristics included in the models were: age, sex, race, ethnicity, education, employment, income, marriage, smoking, exercise, pain, health, and mental health status. The analysis (conducted in SAS) maintained the complex survey structure and included weighting variables to produce national estimates. The a priori alpha value was 0.05.
RESULTS: Overall, 112 (weighted n=1,371,186) US adults with asthma had an ADLL and 2217 (weighted n=35,974,635) had no ADLL. Meanwhile, 202 (weighted n=2,267,453) US adults with asthma had an IADLL while 2125 (weighted n=35,062,562) had no IADLL. Characteristics associated with having an ADLL versus no ADLL included: employed versus unemployed (odds ratio [OR]=0.231, 95% confidence interval [CI]=0.088-0.606), smoker versus non-smoker (OR=0.435, 95% CI=0.207-0.918), and quite a bit/extreme pain versus little/moderate pain (OR=4.430, 95% CI=2.157-9.100). Characteristics associated with having an IADLL versus no IADLL included: white versus another race (OR=0.593, 95% CI=0.363-0.968), employed versus unemployed (OR=0.287, 95% CI=0.145-0.565), married versus not married (OR=0.565, 95% CI=0.336-0.948), and quite a bit/extreme pain versus little/moderate pain (OR=2.862, 95% CI=1.667-4.913).
CONCLUSIONS: The characteristics identified in this study as having an association with ADLL or IADLL offer insights into areas where interventions may be made to help improve the health outcomes of US adults with asthma, and opportunities for future study.
