This exploratory cross-sectional study tested whether dyspnea-related anxiety (Breathlessness Beliefs Questionnaire) relates to reduced physical activity (accelerometer step counts), and whether dyspnea severity (UCSD Shortness of Breath Questionnaire) mediates that relationship.

To date, however, the association between dyspnea severity, objectively measured physical activity (PA), and dyspnea-specific anxiety symptoms has not been explored. In this study, we hypothesized that higher dyspnea-related anxiety (assessed via Breathlessness Beliefs Questionnaire-BBQ) would be associated with reduced PA (assessed via accelerometer-derived step counts), and that dyspnea severity (assessed via the University of California, San Diego Shortness of Breath Questionnaire) would mediate the relationship between dyspnea-related anxiety and PA. Forty-two Veterans were recruited (88% white, 93% male) with a mean age of 69 +/ -6 years, mean FEV1 67 +/ -21%, and mean daily step count (averaged over 14 +/ - 1 days) of 4635 +/-2115 steps. PA and BBQ scores were significantly correlated (r = -0.38, p = .014) . Simple mediation analysis demonstrated a significant indirect effect of BBQ scoreson PA through dyspnea severity (point estimate = -0.26, 95% CI = [-0.43, -0.11]). After accounting for indirect effects, there was no significant main effect of BBQ scores on PA (β = -0.12, p = .44), suggesting dyspnea levels completely mediated the relationship between BBQ scores and PA. Although the direction of relationship between these variables cannot be determined using cross-sectional data, this exploratory study suggests the need for longitudinal studies examining dyspnea-specific anxiety and PA in this population.","cbCait1Zk2wsUmok","https://ap.wps.com/l/cbCait1Zk2wsUmok","pdf",1419013,"English","# Methods\n## Participants and measures\n## Correlation and mediation analysis\n# Results\n## Key associations and mediation effects\n# Implications\n## Need for longitudinal research","[{\"question\":\"What was the study’s main hypothesis about dyspnea-related anxiety and physical activity?\",\"answer\":\"Higher dyspnea-related anxiety was hypothesized to be associated with reduced physical activity measured by accelerometer-derived step counts.\"},{\"question\":\"How was dyspnea severity assessed, and what role did it play in the analysis?\",\"answer\":\"Dyspnea severity was assessed using the University of California, San Diego Shortness of Breath Questionnaire, and it mediated the relationship between dyspnea-related anxiety and physical activity.\"},{\"question\":\"What did the mediation results suggest about how dyspnea-related anxiety affects activity?\",\"answer\":\"After accounting for indirect effects, the direct main effect of dyspnea-related anxiety on physical activity was not significant, indicating dyspnea severity completely mediated the relationship.\"}]","EXPLORING DYSPNEA-RELATED ANXIETY AND PHYSICAL ACTIVITY IN OLDER US VETERANS WITH COPD - Issue S2 - research findings and implications | PDF",1790644938]
