Factors associated with smoking continuation or cessation were analyzed among parents of 4-month-old infants, in order to prepare the basic materials for a smoking cessation support program for pregnant women and their partners. The study focused on the changes in partners' smoking activities upon learning of their partner's pregnancy.
An anonymous self-completed questionnaire was given to parents of 1,198 infants during a 4-month medical checkup in City A of Hyogo prefecture (776 couples) and City B of Gifu prefecture (422 couples). The questionnaire items collected information on age, education, smoking history, current smoking status, and awareness about smoking. The additional items for fathers were occupation, workplace smoking environment, and attitude toward smoking; and the additional items for women were number of children, family composition, and partners' attitudes and behaviors regarding smoking upon learning of their pregnancy. The number of valid answers (for pairs) was 558 (71.9%) in City A and 395 (93.6%) in City B. The data on men who had been smokers before learning of their partner's pregnancy were analyzed. For each area, a comparative item-by-item analysis was performed on data from men who ceased smoking upon learning of the pregnancy (smoking cessation group) and those who continued smoking (smoking continuation group). For logistic regression analysis, the objective variables were the 2 groups, and the explanatory variables were the items showing statistical differences between the groups and the items related to the survey areas.
Of the men whose data were included in the analysis, 210 (37.6%) in City A and 204 (51.6%) in City B had been smokers before learning of their partner's pregnancy. Among these, 16 (7.6%) in City A and 26 (12.7%) in City B ceased smoking after learning of the pregnancy. The results of logistic regression analysis showed that the odds ratio for continuing smoking was 2.77 [95% confidence interval (CI): 1.17-6.57] for men with at least 2 children, 0.05 (95% CI: 0.01-0.18) for those who decided to cease smoking immediately, and 0.19 (95% CI: 0.08-0.44) for those who were strongly encouraged to cease smoking by their pregnant partner upon learning of the pregnancy.
In male smokers who learned of their partner's pregnancy, men with 2 or more children were more likely to continue smoking, while men who considered quitting smoking immediately upon learning of the women's pregnancy, and those whose pregnant partners strongly encouraged them to do so, were more likely to cease smoking.
分析4个月大婴儿的父母中与继续吸烟或戒烟相关的因素，以便为针对孕妇及其伴侣的戒烟支持项目准备基础材料。该研究聚焦于伴侣得知自己怀孕后其吸烟行为的变化。
在兵库县A市（776对夫妇）和岐阜县B市（422对夫妇）对1198名婴儿的父母进行为期4个月的体检时，发放了一份匿名自填问卷。问卷项目收集了年龄、教育程度、吸烟史、当前吸烟状况以及对吸烟的认知等信息。父亲的附加项目包括职业、工作场所吸烟环境以及对吸烟的态度；女性的附加项目包括子女数量、家庭构成以及伴侣得知其怀孕后对吸烟的态度和行为。A市有效回答（成对）数量为558份（71.9%），B市为395份（93.6%）。对在得知伴侣怀孕前吸烟的男性数据进行分析。对每个地区，对得知怀孕后戒烟的男性（戒烟组）和继续吸烟的男性（继续吸烟组）的数据进行逐项目比较分析。对于逻辑回归分析，目标变量为两组，解释变量为两组间显示出统计学差异的项目以及与调查地区相关的项目。
在纳入分析的男性中，A市210名（37.6%）和B市204名（51.6%）在得知伴侣怀孕前吸烟。其中，A市16名（7.6%）和B市26名（12.7%）在得知怀孕后戒烟。逻辑回归分析结果显示，至少有2个孩子的男性继续吸烟的比值比为2.77 [95%置信区间（CI）：1.17 - 6.57]，得知怀孕后立即决定戒烟的男性为0.05（95% CI：0.01 - 0.18），得知怀孕后被其怀孕伴侣强烈鼓励戒烟的男性为0.19（95% CI：0.08 - 0.44）。
在得知伴侣怀孕的男性吸烟者中，有2个或更多孩子的男性更有可能继续吸烟，而得知女性怀孕后立即考虑戒烟的男性以及其怀孕伴侣强烈鼓励他们戒烟的男性更有可能戒烟。
