An examination of how e-cigarette/cigarette use during adolescence is associated with future use during the third trimester of pregnancy.

ABSTRACT

Background: Adolescent e-cigarette use has increased, as has e-cigarette use during pregnancy, yet little is known about how these types of tobacco/nicotine (cigarettes/e-cigarettes) use during adolescence are associated with tobacco/nicotine use during the third trimester of pregnancy among young adults. Methods: National longitudinal data (2013-2018) from the Population Assessment of Tobacco and Health (PATH) study were used. Young adults ages 18-20 who indicated past-year pregnancy made up the analytic sample (N = 246). Logistic regression was used to evaluate the association between history of past 30-day use of cigarettes/e-cigarettes during adolescence (i.e., 14-17) and later use during the third trimester of pregnancy among young women (i.e., 18-20). Results: Within the sample of young women who indicated a pregnancy during the past year, 18.9% indicated smoking cigarettes and 4.2% indicated using e-cigarettes during their last trimester. Cigarette smoking in adolescence (wave 1 or 2) was associated with cigarette use during the last trimester (aOR = 4.76, 95% CI = 1.36, 16.6); however, e-cigarette use during adolescence was not associated with either cigarette or e-cigarette use during the third trimester of pregnancy. Conclusions: Tobacco/nicotine prevention in early adolescence has implications for preventing tobacco/nicotine-related harms during pregnancy among young adults. Intervention programs and clinicians informed about various types of tobacco/nicotine are needed to address tobacco/nicotine cessation among adolescents to prevent consequences of tobacco/nicotine use during pregnancy.
