NCT03480373

Brief Summary

Aim 1: To compare the overall toxicant exposure in pregnant women who use electronic cigarettes (e-cigs, vapor, e-liquid, e-juice, vape, vaping devices) compared to women who smoke conventional cigarettes. Aim 2. To compare toxicant exposure and birth outcomes among infants born to pregnant women who use e-cigs compared to women who smoke conventional cigarettes. Aim 3. To explore potential mechanisms by which e-cigs could influence birth weight.

Outcome Measures

Primary Outcomes (1)

  • To compare the overall toxicant exposure in pregnant women who use electronic cigarettes compared to women who smoke conventional cigarettes.

    The overall toxicant exposure will be measured at each trimester and adjusted for potential confounding covariates. A multivariate analysis of variance (MANOVA) with repeated measures will be used to evaluate the pregnant women who use electronic cigarettes compared to women who smoke conventional cigarettes at each trimester.

    9 months
