Association between tobacco product use and respiratory health and asthma-related interference with activities among U.S. Adolescents.

ABSTRACT

Tobacco use adversely affects long-term respiratory health. We examined the relationship between sole and dual tobacco product use and both respiratory health and respiratory-related quality of life during adolescence in the U.S. Using adolescent data (baseline age 12-17) from Waves 4.5 (data collected from December 2017-December 2018) and 5 (data collected from December 2018-November 2019) of the Population Assessment of Tobacco and Health Study, we examined the associations between combustible (i.e., cigarette or cigar), vaped, and dual (i.e., both cigar/cigarette and e-cigarette) tobacco/nicotine use at baseline and two respiratory symptoms (all adolescents, n = 11,748) and new asthma diagnosis (adolescents with no baseline diagnosis, n = 9,422) at follow-up. Among adolescents with asthma (Wave 5, n = 2,421), we estimated the association between current tobacco use and the extent to which asthma interfered with daily activities. At follow-up, 12.3 % of adolescents reported past 12-month wheezing/whistling, 17.4 % reported past 12-month dry cough, and 1.9 % reported newly diagnosed asthma. Baseline current cigarette/cigar smoking was associated with subsequent wheezing/whistling and baseline report of another tobacco product use pattern was associated with subsequent asthma diagnosis. Among adolescents with asthma, 5.7 % reported it interfering with activities some of the time and 3.1 % reported interference most/all of the time in the past 30 days. Past 30-day sole cigarette/cigar smoking and dual use was positively associated with asthma-related interference with activities compared to never tobacco use and sole e-cigarette use. Combustible and dual tobacco use pose direct risk to respiratory health and indirect risk to quality of life through respiratory health.
