BACKGROUND Identifying predictors of tobacco use patterns that differ in harm among reproductive-aged women may inform efforts to protect women and children against adverse health impacts of tobacco use. METHODS Changes in tobacco use patterns were examined among women (18-49 years) who completed Wave 1 (W1) and Wave 2 (W2), or W2 and Wave 3 (W3) of the U.S. Population Assessment of Tobacco and Health (PATH, 2013-2016) study, and were using cigarettes, filtered cigars and/or cigarillos in the first wave over which data were included for that respondent (Time 1; T1). We examined the proportion of respondents whose tobacco use transitions from T1 to Time 2 (T2) were harm-maintaining (continued using combusted tobacco), harm-reducing (transitioned to electronic nicotine delivery systems (ENDS), or harm-eliminating (quit tobacco). Multinomial logistic regressions (with harm-maintaining as the baseline category) were conducted to examine associations between ENDS use, demographic, and psychosocial characteristics with each transition. RESULTS A majority of women (83 %) exhibited harm-maintaining transitions, followed by harm-eliminating (14.7 %) and harm-reducing (2.3 %) transitions. Use of ENDS at T1 was associated with increased odds of harm reduction and decreased odds of harm elimination. Younger women were more likely to make both harm-reducing and harm-eliminating transitions. Increased educational attainment, identifying as Black or Hispanic, increased psychiatric symptoms, and pregnancy were associated with harm elimination, whereas living at or above poverty was associated with harm reduction. CONCLUSIONS Study results contribute new information on the impact of ENDS, sociodemographic characteristics, psychiatric symptoms, and pregnancy on tobacco use transitions among reproductive-aged women.

电子尼古丁传送系统和其他受访者特征对美国全国育龄妇女样本烟草使用转变的影响。

背景 确定对育龄妇女危害不同的烟草使用模式的预测因素可以为保护妇女和儿童免受烟草使用对健康造成不利影响的努力提供信息。方法 对完成美国烟草与健康人口评估 (PATH, 2013-2016）研究，并在第一波中使用香烟、过滤雪茄和/或小雪茄，其中包含该受访者的数据（时间 1；T1）。我们研究了从 T1 到时间 2 (T2) 的烟草使用转变为维持危害（继续使用燃烧的烟草）、减少危害（过渡到电子尼古丁输送系统 (ENDS)）或消除危害（戒烟）的受访者比例。 ). 进行多项逻辑回归（以维持伤害作为基线类别）来检查电子尼古丁传送系统使用、人口统计和心理社会特征与每次转变之间的关联。结果 大多数女性 (83 %) 表现出维持伤害转变，其次是消除伤害 (14.7 %) 和减少伤害 (2.3 %) 转变。在 T1 时使用 ENDS 与减少伤害的几率增加和消除伤害的几率降低相关。年轻女性更有可能同时减少伤害和伤害-消除过渡。教育程度的提高、被认定为黑人或西班牙裔、精神症状的增加和怀孕与消除危害有关，而生活在贫困或贫困以上则与减少危害有关。结论 研究结果提供了关于 ENDS、社会人口特征、精神症状和怀孕对育龄妇女烟草使用转变的影响的新信息。
