Abstract
Background
Subjective cognitive decline (SCD), an early indicator of cognitive impairment, may affect COPD care and outcomes, yet its sociodemographic associations in Chronic Obstructive Pulmonary Disease (COPD) remain poorly understood.
Objective
To investigate the prevalence of SCD among people with COPD across different age groups and identify associations between demographics, risk behaviors, comorbidities, and self-reported SCD.
Design
Pooled 2019 BRFSS data from 24 states using the Cognitive Decline module were analyzed. Logistic regression assessed relationships between demographics, behaviors, comorbidities, and SCD, adjusting for confounders.
Participants
A total of 12,003 adults with COPD aged ≥ 45 were included in the study (weighted population = 617,792).
Main Measures
Prevalence of SCD, associations with demographics, behaviors, health status, income, employment, and smoking.
Key Results
Among adults with COPD, 24.1% reported SCD. The prevalence among those with SCD was highest in those aged 55–64 (30.2%), followed by 65–74 (24.5%) and 45–54 (23.1%). Older age (55 to 64: AOR = 0.63, 95% CI: 0.49 – 0.80; 65 to 74: AOR = 0.54, 95% CI: 0.40 – 0.72; 75 to 79: AOR = 0.41, 95% CI: 0.29 – 0.60; 80 + : AOR = 0.47, 95% CI: 0.32 – 0.69) and higher annual income (e.g., $25,000 to $49,999: AOR = 0.80, 95% CI: 0.65 – 0.99; $50,000 to $74,999: AOR = 0.68, 95% CI: 0.51 – 0.91) were associated with lower odds of reporting SCD, while unemployment (AOR = 1.73, 95% CI: 1.33 – 2.27), history of stroke (AOR = 1.35, 95% CI: 1.05 – 1.74), and fair or poor health (AOR = 0.47, 95% CI: 0.39 – 0.57) were linked to higher odds of reporting SCD.
Conclusions
Among adults with COPD, the prevalence of SCD varied by age, with the highest rates in those aged 55–64, and was independently associated with socioeconomic factors and health risks, emphasizing the complex interplay of demographic and health-related factors in SCD.
