Asthma-COPD Overlap Syndrome (ACOS) among Adults — United States, 2015
Sangeeta Gupta, MD, MPH; Raymond Tutu, PhD
Introduction: The objective of this study was to use data from the Behavioral Risk Factor Surveillance System (BRFSS) to examine the prevalence of asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) by state and by select sociodemographic groups among U.S. adults.
Methods: Data from 2015 BRFSS were analyzed to determine prevalence of ACOS. COPD and asthma prevalence data were also provided for quick comparison.
Results: Nationally, 2.2 percent of adults were estimated to have ACOS. State prevalence varied considerably, ranging from as low as 1.3 percent in Colorado to as high as 5.0 percent in Kentucky and West Virginia. Smoking tobacco and obesity were significantly correlated with ACOS. Respondents with ACOS also were more likely to report disability. ACOS increased with age and was more prevalent in women.
Conclusion: ACOS has been described and acknowledged recently as a distinct clinical entity with a greater health burden and worse health outcomes than either COPD or asthma alone. This study is the first analysis of ACOS prevalence in all 50 states (plus the District of Columbia and Puerto Rico).
