Although observational data suggest that men's attempts and behavior at quitting smoking are often stimulated during their spouses' pregnancy, few studies have systematically examined this phenomenon.
This was a cross-sectional study which examined Chinese men's smoking behaviors during and after their wives' pregnancy. Women who visited community health centers for routine immunization of their children were approached. Information was mainly collected on men's tobacco use before, during and after pregnancy in July to August 2011. Individual and socio-environmental factors were examined by non-conditional logistical regression analysis to find potential reasons behind men's quitting during pregnancy and maintained this change till the post-partum period.
Totally 765 of 811 eligible women (94.3%) completed the interview. Prior to pregnancy, 42.9% of husbands smoked; this decreased to 36.34% during pregnancy, a reduction of 6.53%. Although the rate increased to a higher level (43.79%) after delivery, positive changes in men's smoking behavior were detected. One-third (29.88%) reduced the daily number of cigarettes smoked, and nearly half (45.12%) relocated themselves to smoke when their pregnant wives were nearby. Noticeably, those who quit were most likely occasional smokers (Odds Ratio(OR) = 4.83, 95%CI [2.22, 10.48]), smoking less than ten years (OR = 2.80, 95%CI [1.19, 6.58]), not smoking at home (OR = 4.48, 95%CI [1.94, 10.39]), not smoking for social use (OR = 4.05, 95%CI [1.74, 9.41]), under lower financial pressure after the birth of child (OR = 5.28, 95%CI [2.14, 13.02]) and influenced by family members (OR = 2.82, 95%CI [1.25, 6.38]). However, only 22% of spontaneous cessation was maintained postpartum. Most relapses occurred within 6 months after delivery.
Pregnancy offers an opportunity to decrease smoking amongst Chinese males. Intervention programs involving expectant fathers may be effective to further reduce prevalence of smoking among men in China.
尽管观察数据表明男性尝试戒烟的行为及其戒烟行为通常在其配偶怀孕期间受到刺激，但很少有研究系统地考察过这一现象。
这是一项横断面研究，考察了中国男性在其妻子孕期及产后的吸烟行为。研究人员接触了那些带孩子到社区卫生中心进行常规免疫接种的女性。主要收集了2011年7月至8月期间男性在妻子怀孕前、孕期及产后的吸烟情况。通过非条件逻辑回归分析考察个体及社会环境因素，以找出男性在孕期戒烟并在产后维持这一变化的潜在原因。
811名符合条件的女性中有765名（94.3%）完成了访谈。怀孕前，42.9%的丈夫吸烟；孕期这一比例降至36.34%，下降了6.53%。尽管产后这一比例升至更高水平（43.79%），但男性吸烟行为仍出现了积极变化。三分之一（29.88%）的男性减少了每日吸烟量，近一半（45.12%）的男性在怀孕的妻子身边时会换地方吸烟。值得注意的是，那些戒烟的男性最有可能是偶尔吸烟者（比值比（OR）=4.83，95%置信区间[2.22, 10.48]），吸烟年限少于10年（OR = 2.80，95%置信区间[1.19, 6.58]），不在家中吸烟（OR = 4.48，95%置信区间[1.94, 10.39]），吸烟并非出于社交目的（OR = 4.05，95%置信区间[1.74, 9.41]），孩子出生后经济压力较小（OR = 5.28，95%置信区间[2.14, 13.02]）以及受到家庭成员影响（OR = 2.82，95%置信区间[1.25, 6.38]）。然而，只有22%的自发戒烟行为在产后得以维持。大多数复吸发生在产后6个月内。
怀孕为降低中国男性吸烟率提供了一个契机。涉及准父亲的干预项目可能会有效进一步降低中国男性的吸烟率。
