To study determinants for changes in maternal smoking behaviour during and after pregnancy, questionnaire information on smoking habits was recorded in a cohort of 3710 Norwegian women during early pregnancy, at delivery, and one year later. Of 3039 cohabiting women with complete information on smoking at all three occasions 31% smoked in early pregnancy 23% in the late pregnancy and 28% one year after delivery. Among the cohabiting mothers who smoked in early pregnancy, 44% stopped during pregnancy. After adjusting for confounding factors, the odds ratio for smoking cessation among these women who had cohabitants who smoked as opposed to not smoking was 0.2 (95% CI: 0.1-0.2). Among cohabiting non-smoking women during late pregnancy the odds ratio for being a smoker one year after child birth was 3.0 (95% CI: 2.2-4.0), if their cohabitants smoked as opposed to not smoking. The women's smoking behaviour changes considerably during and after pregnancy and their cohabitants' smoking seems to be a major determinant for changes in their smoking behaviour.
为研究孕期及产后母亲吸烟行为变化的决定因素，在一个由3710名挪威女性组成的队列中，于孕早期、分娩时及产后一年记录了有关吸烟习惯的问卷信息。在所有三个时间点均有吸烟情况完整信息的3039名同居女性中，31%在孕早期吸烟，23%在孕晚期吸烟，28%在产后一年吸烟。在孕早期吸烟的同居母亲中，44%在孕期戒烟。在对混杂因素进行调整后，与同居伴侣不吸烟的女性相比，同居伴侣吸烟的女性戒烟的优势比为0.2（95%置信区间：0.1 - 0.2）。在孕晚期不吸烟的同居女性中，如果其同居伴侣吸烟而非不吸烟，那么产后一年成为吸烟者的优势比为3.0（95%置信区间：2.2 - 4.0）。女性在孕期及产后的吸烟行为变化很大，其同居伴侣的吸烟情况似乎是其吸烟行为变化的一个主要决定因素。
