摘要
PURPOSE:Electronic Nicotine Delivery Systems (ENDS) use among adolescents has increased greatly over the past decade, but its impact on chronic respiratory health conditions, like asthma, is not fully understood.
METHODS:We examined data from Waves 1-5 (2013-2019) of the Population Assessment of Tobacco and Health Study using discrete time hazard models to analyze the association between time-varying tobacco product use and incident diagnosed asthma among adolescents aged 12-17 years at baseline. We lagged the time-varying exposure variable by one wave and categorized respondents by current use status (1+ days in the past 30 days): never or non-current, exclusive cigarette, exclusive ENDS, and dual cigarette and ENDS use. We also controlled for sociodemographic (age, sex, race/ethnicity, parental education) and other risk factors (urban/rural setting, secondhand smoke exposure, household combustible tobacco use, body mass index).
RESULTS:At baseline, over half the analytic sample (n = 9,141) was 15-17 years old (50.4%), female (50.2%), and non-Hispanic White (55.3%). Adolescents who exclusively smoked cigarettes had a statistically significant higher risk of incident diagnosed asthma at follow-up (adjusted Hazard Ratio (aHR): 1.68, 95% confidence interval (CI): 1.21-2.32) compared to those not currently using cigarettes or ENDS, but adolescents using ENDS exclusively (aHR: 1.25, 95% CI: 0.77-2.04) or in combination with cigarettes (aHR: 1.54, 95% CI: 0.92-2.57) did not.
DISCUSSION:Short-term exclusive cigarette use was associated with a higher risk of incident diagnosed asthma over five years of follow-up among adolescents. We did not find conclusive evidence for an association between exclusive ENDS or dual use and incident diagnosed asthma.
