Potential risk factorsfor maternal and child health should therefore be identifiedand reduced as early as possible. The consumption of e-ciga-rettes represents one of these potential risk factors. Exploringrisk perceptions about e-cigarette use during pregnancy canprovide early indications of possible user motives. Therefore,our mixed methodsSTudy onE-cigarettes andPregnancy(STEP) aimed to comprehensively analyze risk perceptionsabout e-cigarette use during pregnancy based on anInte-gratedHealthBeliefModel (IHBM). This paper describes thestudy design, methods, sample population and limitations ofSTEP. Methods: Our sequential mixed methods study combinedqualitative and quantitative approaches. In the qualitativesection of the study which preceded the quantitative part ofthe study, we aimed to characterize risk perceptions aboute‑cigarette use during pregnancy. We used a netnographic re-search approach which analyzed discussion threads in onlineforums dealing with e-cigarette use during pregnancy. Theanalysis was based on an IHBM. Identified themes were incor-porated in the questionnaire which was developed for the quantitative part of the study. The quantitative section aimedto quantify, among other things, perceived threats, barriersand benefits and to explore differences in risk perception ac-cording to sociodemographic characteristics and tobacco ande-cigarette usage. Results: In the qualitative section, 1552 posts in 25 online dis-cussion threads dealing, inter alia, with e-cigarette use duringpregnancy were identified. The quantitative part looked atthe responses in the questionnaires handed in by 575 preg-nant women who attended a hospital in Hamburg (Germany)from April 2018 to January 2019 (response rate: 27.5\%). Conclusion: Data collection was successful for both the qual-itative and quantitative parts of the study. When interpretingthe results of STEP, different limitations should be taken intoaccount. The results of STEP provide starting points for thedevelopment of tailored preventive measures for pregnantwomen.}, language = {en} } @misc{SchillingSpallekMauletal., author = {Schilling, Laura and Spallek, Jacob and Maul, Holger and Tallarek, Marie and Schneider, Sven}, title = {Active and Passive Exposure to Tobacco and e-Cigarettes During Pregnancy}, series = {Maternal and Child Health Journal}, volume = {25}, journal = {Maternal and Child Health Journal}, number = {4}, issn = {1092-7875}, doi = {10.1007/s10995-020-03037-8}, pages = {656 -- 665}, abstract = {Objectives Active and passive exposure to tobacco cigarettes during pregnancy is associated with multiple negative health outcomes for the fetus. In addition, exposure to e-cigarettes has been progressively discussed as a new threat to fetal health. Until now, there has been a lack of studies examining active and passive exposure to tobacco and e-cigarettes among pregnant women. The objective of our current STudy on E-cigarettes and Pregnancy (STEP) was to advance and complement the current knowledge regarding active and passive exposure to tobacco and e-cigarettes before pregnancy and during early and late pregnancy. Methods One element of the STEP study was a quantitative cross-sectional design: A sample of 540 pregnant women recruited at an obstetrician clinic in Hamburg from April 2018 to January 2019 were surveyed once via a standardized questionnaire and provided complete information regarding their consumption of tobacco and e-cigarettes. We performed a descriptive analysis of tobacco and e-cigarette use before pregnancy and during early and late pregnancy, as well as bivariate analysis of these variables with sociodemographic determinants. Passive exposure was assessed by asking the participating pregnant women about the consumption of tobacco and e-cigarettes by their partners, in general, and in their homes. Results Before pregnancy, 20.0\% of the participants used tobacco cigarettes exclusively, 1.3\% used e-cigarettes exclusively, and 6.5\% were dual users. Educational level was significantly associated with tobacco cigarette use (p < 0.001) and dual use (p = 0.047) before pregnancy. During early (late) pregnancy, 8.7\% (2.8\%) used tobacco cigarettes and 0.4\% (0.0\%) used e-cigarettes exclusively. Twenty-point nine percent of women's partners consumed tobacco cigarettes exclusively, 2.7\% consumed e-cigarettes exclusively, and 2.7\% consumed both. A total of 8.5\% (16.7\%) of the partners who consumed tobacco cigarettes exclusively (e-cigarettes exclusively) did so in the women's homes. Conclusions for Practice Among pregnant women, the use of tobacco cigarettes remains prominent before and during pregnancy, while e-cigarette use predominately occurs before pregnancy. Our study shows that pregnant women are frequently exposed to their partners' tobacco and e-cigarette use within their homes. Strategies to reduce such exposure should be further intensified. Significance In the last decade, e-cigarettes have become popular, and e-cigarette use has been increasing, even among pregnant women. However, there is a lack of knowledge concerning the exposure to e-cigarettes before pregnancy and during early and late pregnancy, as well as studies comparing e-cigarettes and tobacco cigarettes. The current study found that active exposure to e-cigarettes before pregnancy is high, while exposure during pregnancy is marginal. In contrast, exposure to tobacco cigarettes before and in early pregnancy is high but decreases during late pregnancy. In addition, the results of our study show that pregnant women are passively exposed to tobacco and e-cigarettes at home. Pregnant women should be advised against exposing themselves, actively or passively, to tobacco and e-cigarette smoke.}, language = {en} }
