ABSTRACT

OBJECTIVE: To evaluate the risk of adverse birth outcomes among adults who use electronic cigarettes (e-cigarettes) before and during pregnancy. METHODS: Data from the 2016-2018 PRAMS (Pregnancy Risk Assessment Monitoring System) were used to assess the association between e-cigarette use during the 3 months before and last 3 months of pregnancy among 79,176 individuals with a recent live birth and the following birth outcomes: preterm birth, small for gestational age, and low birth weight (LBW). Adjusted prevalence ratios were generated using average marginal predictions from multivariable logistic regression models. Models were stratified by prenatal combustible cigarette smoking and frequency of e-cigarette use (daily or less than daily use). RESULTS: In the 3 months before pregnancy, 2.7% (95% CI 2.6-2.9%) of respondents used e-cigarettes; 1.1% (95% CI 1.0-1.2%) used e-cigarettes during the last 3 months of pregnancy. Electronic cigarette use before pregnancy was not associated with adverse birth outcomes. Electronic cigarette use during pregnancy was associated with increased prevalence of LBW compared with nonuse (8.1% vs 6.1%; adjusted prevalence ratio 1.33; 95% CI 1.06-1.66). Among respondents who did not also smoke combustible cigarettes during pregnancy (n=72,256), e-cigarette use was associated with higher prevalence of LBW (10.6%; adjusted prevalence ratio 1.88; 95% CI 1.38-2.57) and preterm birth (12.4%; adjusted prevalence ratio 1.69; 95% CI 1.20-2.39). When further stratified by frequency of e-cigarette use, associations were seen only for daily users. CONCLUSION: E-cigarette use during pregnancy, particularly when used daily by individuals who do not also smoke combustible cigarettes, is associated with adverse birth outcomes.

ABSTRACT

OBJECTIVE: To explore risk perceptions of traditional and nontraditional tobacco products (NTPs) among young adult smokers. METHODS: Focus groups with African Americans, non-Hispanic whites, and Hispanics. Risk ratings of light, regular, and menthol cigarettes and of NTPs and marijuana and cigarettes were compared. RESULTS: Participants tended to view light cigarettes as safer than regular cigarettes. Shisha and herbal products were rated as safer than traditional cigarettes, but there were differences in ratings by race/ethnicity, related to preferred cigarette variety. CONCLUSIONS: Health communication messages about the use of cigarettes and NTPs should consider risk perceptions about the products and racial/ethnic differences.
