Secondhand smoke (SHS) from partners is a major source of exposure for non-smoking women. However, epidemiological studies have rarely examined social factors associated with continued and indoor smoking among pregnant women's partners.
We analyzed data on 6,091 partners of non-smoking pregnant women in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Partners' age, education, income, workplace SHS exposure (almost never or sometimes, almost every day), and pregnant women's smoking history (never, quit before pregnancy awareness, quit after pregnancy awareness) were used as social factors. Multiple logistic regression analyses were conducted to examine the associations of social factors with partners' continued smoking and indoor smoking.
Among 2,432 smoking partners, 2,237 continued to smoke after pregnancy awareness. Workplace SHS exposure was associated with increased risk of partners' continued smoking: the odds ratio of workplace SHS exposure almost every day compared with almost never or sometimes was 2.08 (95% confidence interval, 1.52-2.83). Women's quitting smoking after-but not before-pregnancy awareness was associated with decreased risk of partners' continued smoking: the odds ratio of women's quitting after pregnancy awareness compared with never smoking was 0.57 (95% confidence interval, 0.40-0.80). About one-third of partners who continued to smoke did so indoors. Older age, lower education, workplace SHS exposure, and women's quitting smoking after pregnancy awareness were associated with increased risk of partners' indoor smoking.
Workplace SHS exposure and pregnant women's smoking history were associated with continued smoking and indoor smoking among partners of non-smoking pregnant women.
来自伴侣的二手烟（SHS）是非吸烟女性的主要暴露源。然而，流行病学研究很少检查与孕妇伴侣持续和室内吸烟相关的社会因素。
我们分析了东北医疗百万基因组学计划生育与三代队列研究中 6091 名非吸烟孕妇伴侣的数据。伴侣的年龄、教育程度、收入、工作场所 SHS 暴露（几乎从不或有时，几乎每天）以及孕妇的吸烟史（从不、怀孕前戒烟意识、怀孕后戒烟意识）被用作社会因素。采用多因素逻辑回归分析，探讨社会因素与伴侣持续吸烟和室内吸烟的关系。
在 2432 名吸烟伴侣中，有 2237 名在怀孕后仍继续吸烟。工作场所 SHS 暴露与伴侣持续吸烟的风险增加有关：与几乎从不或有时相比，每天暴露于工作场所 SHS 的比值比为 2.08（95%置信区间，1.52-2.83）。女性在怀孕后而非怀孕前戒烟与伴侣持续吸烟的风险降低有关：与从不吸烟相比，女性在怀孕后戒烟的比值比为 0.57（95%置信区间，0.40-0.80）。大约三分之一继续吸烟的伴侣在室内吸烟。年龄较大、教育程度较低、工作场所 SHS 暴露以及女性在怀孕后戒烟与伴侣室内吸烟的风险增加有关。
工作场所 SHS 暴露和孕妇吸烟史与非吸烟孕妇伴侣的持续吸烟和室内吸烟有关。
