Abstract Rationale: Chronic lung diseases, such as COPD and bronchiectasis (BE), may manifest differently by gender in symptom presentation, time to diagnosis, and overall disease burden. This study aimed to assess perceptions of individuals with self-reported COPD, BE, or non-tuberculous mycobacteria (NTM) regarding healthcare experiences and disease-related symptoms. Methods: This cross-sectional study analyzed data from US-based and international participants with self-reported COPD, BE, or NTM using an online survey. Participants were recruited through the COPD Foundation (COPDF) social media channels and completed a questionnaire developed with input from a steering committee that included COPDF leadership, physician-researchers, and patient stakeholders. The survey explored participants’ experiences with healthcare, disease burden, and self-reported symptoms. A subset of women answered additional questions regarding menopause-related symptom changes. Descriptive statistics were calculated and analyzed across self-identified genders and two disease groups: COPD (with or without BE or NTM) and BE (with or without NTM or COPD). Continuous variables were compared using ANOVA, while categorical variables were analyzed using chi-square or Fisher's exact test. Results: Of 632 respondents included in these analyses (mean age 70±9 years, 74% women), 68% reported COPD and 32% BE (both groups included individuals with or without additional diagnoses). Women with COPD were younger than men (p=0.048) and had a shorter duration between symptom onset and initial healthcare visit (< 6 months) (p<0.01). Compared to men, a higher proportion of women with COPD reported that their diagnosis was not explained by a healthcare provider (p=0.0381) and that they experienced anxiety, depression, or fear related to their diagnosis (p=0.0074). Among participants with BE, men and women were similar in age, though a higher proportion of men had shorter intervals (<6 months) between initial healthcare visit and confirmed diagnosis (p=0.0244) and received their diagnosis during hospitalization (p=0.0244). Both men and women across diagnoses reported similar levels of disease management burden, pulmonologist visit frequency, CAAT scores, numbers of comorbidities, and financial difficulties related to their lung condition. Over 75% of women identified as post-menopausal, with approximately one-third reporting worsening pulmonary symptoms associated with menopause. Conclusions: Despite similarities in disease management and comorbidity burden, women with BE and men with COPD reported longer times to initial healthcare visits and diagnostic delays, respectively. Additionally, over one-third of post-menopausal women experienced symptom exacerbation since menopause. These findings underscore the need to further explore gender-based differences and disparities in healthcare access and pulmonary care to enhance lung health outcomes across genders.
