| description | Introduction
Chronic obstructive pulmonary disease (COPD) is associated with cognitive impairment, but consequences of this association on a person’s functional limitations are unclear. We examined the association between COPD and increased confusion and memory loss (ICML) and functional limitations among adults with COPD.
Methods
We studied adults aged 45 years or older in 21 states who participated in the 2011 Behavioral Risk Factor Surveillance System (n = 102,739). Presence of COPD was based on self-reported physician diagnosis. ICML was based on self-report that confusion or memory loss occurred more often or worsened during the prior year. ICML-associated difficulties were defined as giving up household chores and former activities, decreased ability to work or engage in social activities, or needing help from family or friends during the prior year due to ICML. General limitations were defined as needing special equipment as a result of a health condition, having had activity limitations for 2 weeks or more in the prior month, or being unable to work. Multivariable models were adjusted for demographics, health behaviors or conditions, and frequent mental distress.
Results
COPD was reported by 9.3% of adults. ICML was greater among those with COPD than among those without COPD (25.8% vs 11%; adjusted prevalence ratio [aPR], 1.48; 95% confidence interval [CI], 1.32%–1.66%). People with COPD, either with or without ICML, were more likely than those without COPD to report general functional limitations. Among people reporting ICML, those with COPD were more likely to report interference with work or social activities than those without COPD (aPR, 1.17; 95% CI, 1.01%–1.36%).
Conclusion
Functional limitations were greater among those with COPD than among those without, and ICML may further affect these limitations. Results from our study can inform future studies of self- management and functional limitations for people with COPD. |
