Relationship Between Tobacco Product Use and Health-Related Quality of Life Among Individuals With COPD in Waves 1-5 (2013-2019) of the Population Assessment of Tobacco and Health Study
Abstract
Introduction
We examined the association between tobacco product use and health-related quality of life (HRQOL) among individuals with COPD in Waves 1-5 of the Population Assessment of Tobacco and Health (PATH) Study.
Methods
Adults ≥40 years with an ever COPD diagnosis were included in cross-sectional (Wave 5) and longitudinal analyses (Waves 1 to 5). Tobacco use included 13 mutually exclusive categories of past 30-day (P30D) single use and polyuse with P30D exclusive cigarette use and ≥5 year cigarette cessation as reference groups. Multivariable linear regression and generalized estimating equations (GEE) were used to examine the association between tobacco use and HRQOL as measured by the PROMIS Global-10 questionnaire.
Results
Of 1,670 adults, 79.4% ever used cigarettes; mean (SE) pack-years was 30.9 (1.1). In cross-sectional analysis, P30D exclusive cigarette use and e-cigarette/cigarette dual use were associated with worse HRQOL compared to ≥5-year cigarette cessation. Compared to P30D exclusive cigarette use, never tobacco use and ≥5 year cigarette cessation were associated with better HRQOL, while e-cigarette/cigarette dual use had worse HRQOL. Longitudinally (n=686), e-cigarette/cigarette dual use was associated with worsening HRQOL compared to both reference groups; only never tobacco use was associated with higher HRQOL over time compared to P30D exclusive cigarette use.
Conclusions
E-cigarette/cigarette dual use was associated with worse HRQOL compared to…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 1,670 participants or records.
