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

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.

The association of current exclusive e-cigarette use and dual use of e-cigarettes and cigarettes with psychological distress among U.S. adults.

This observational study examines the association of current e-cigarette use and dual use of e-cigarettes and cigarettes (dual use) with psychological distress among U.S. adults. We differentiate dual use based on the smoking frequency and compare the relationship between dual use and psychological distress to that of exclusive cigarette smoking with the same smoking frequency. Using data from the 2015-2018 National Health Interview Surveys, we analyzed adults aged 18+ (N = 55,780) who currently use e-cigarettes or/and cigarettes and have no history of using other tobacco products, and adults who never used any tobacco. Multinomial logistic regression models estimate the association of current e-cigarette use and dual use with psychological distress severity (no/mild, moderate, and severe).In the sample, 15.3% and 2.9% of adults experienced moderate and severe psychological distress. Compared to never tobacco users, current exclusive e-cigarette users and dual users who smoke daily had higher odds of moderate and severe psychological distress. Dual users who smoke nondaily had higher odds of moderate, but not severe psychological distress than never tobacco users. Compared to exclusive daily smokers, dual users with daily smoking had higher odds of moderate and severe psychological distress. Compared to exclusive nondaily smokers, dual users with nondaily smoking had higher odds of moderate but not severe psychological distress. Our findings suggest that exclusive e-cigarette use is associated with psychological distress severity. Dual use is associated with higher odds of psychological distress severity compared to never tobacco users and exclusive cigarette smoking, and this association differs by smoking frequency.

Does Experienced Discrimination Explain Patterns of Menthol Use Among Young Adults? Evidence from the 2014 San Francisco Bay Area Young Adult Health Survey.

BACKGROUND: Young adults are at high risk for using flavored tobacco, including menthol and underrepresented populations, such as Latino and African American young adults, are at particular risk. OBJECTIVES: The purpose of this study is to identify sociodemographic correlates of menthol use among young adult smokers and examine the potential role of experienced discrimination in explaining any associations. METHODS: We conducted a probabilistic multimode household survey of young adults (aged 18-26) residing in Alameda and San Francisco Counties in California in 2014 (n = 1,350). We used logistic regression to evaluate associations between menthol cigarette use and experienced discrimination among young adult smokers as well as with respect to sociodemographic, attitudinal, and behavioral predictors. Interactions between experienced discrimination and race/ethnicity, sex and LGB identity were also modeled. RESULTS: Latino and non-Hispanic Black young adult smokers were more likely to report current menthol use than non-Hispanic Whites, while those with college education were less likely to do so. Experienced discrimination mediated the relationship between race and menthol use for Asian/Pacific Islander and Multiracial young adult smokers with odds of use increasing by 32 and 42% respectively for each additional unit on the experienced discrimination scale. Conclusions/Importance: Latino and African American young adult smokers have disproportionately high menthol use rates; however, discrimination only predicted higher use for Asian/Pacific Islander and Multiracial young adult smokers. Limits on the sale of menthol cigarettes may benefit all nonwhite race/ethnic groups as well as those with less education.
