Asthma Morbidity, Comorbidities, and Modifiable Factors Among Older Adults.


ABSTRACT: BACKGROUND:Asthma morbidity is increased among older adults, especially older adult women. Interventions to improve asthma control in this population are not well described. OBJECTIVE:The objective of this study was to identify risk factors (including modifiable factors) associated with asthma-related hospitalizations and emergency department or urgent care center visits (ED/UCV) among older adults. A secondary objective was to investigate sex differences in variables relevant to asthma control. METHODS:Data were obtained from 14,076 older adults ?65 years with active asthma participating in the 2006-2010 Behavioral Risk Factor Surveillance System Asthma Call-back Survey (a random-digit dialed survey) in 40 US states, the District of Columbia, and Puerto Rico, representative of >2.6 million persons. Weighted, adjusted logistic regression was conducted. RESULTS:One or more asthma-related hospitalizations in the past year were reported by 5.7% (95% confidence interval [95% CI] = 5.0% to 6.4%) of participants; 10.6% (95% CI = 9.7% to 11.5%) reported ?1 asthma-related ED/UCV. Compared with older adults without asthma-related hospitalizations, adjusted odds were higher among those with ?1 asthma-related hospitalization for chronic obstructive pulmonary disease (COPD), coronary artery disease, depression, cockroaches or mold in the home, and cost barriers to asthma-related health care or medication. All these factors, except for cockroaches, were associated with asthma-related ED/UCV. Compared with males, adjusted odds were higher among females for COPD, depression, obesity, and cost barriers to asthma-related health care or medication. CONCLUSIONS:Among older adults, asthma-related hospitalizations and ED/UCV were associated with clinical comorbidities, mold in the home, and financial barriers to asthma-related health care. Interventions addressing modifiable factors could reduce asthma morbidity among older adults.
