目的：调查调整母亲的婴儿喂养意愿后，母亲吸烟是否仍然与母乳喂养时间缩短有关。方法：在一项纵向队列研究中招募了居住在英国雅芳市、预计在1991年4月1日至1992年12月31日期间分娩的孕妇。主要结局指标包括妊娠 32 周时的母婴喂养意愿：第一周的意愿、第一个月剩余时间的意愿以及第 2 至 4 个月的意愿。母亲吸烟的定义是在怀孕期间任何时间报告的任何吸烟情况。母乳喂养开始时间和持续时间的数据基于产后 6 个月的调查问卷，如有必要，辅以 15 个月调查问卷的数据。结果：与不吸烟者相比，怀孕期间吸烟的女性在 6 个月时不进行母乳喂养的调整后比值比为 1.5（95% CI：1.3 - 1.7）（根据母亲年龄、教育程度和意愿进行调整）。对产后前 6 个月母乳喂养持续时间的生存分析发现，计划母乳喂养时间少于 1 个月的女性在任何给定时间停止母乳喂养的可能性比计划母乳喂养至少 4 个月的女性高 78%，而吸烟者停止母乳喂养的可能性比不吸烟者高 17%。母乳喂养而不是吸烟对母乳供应的生理影响。
Aim: To investigate whether maternal smoking remains associated with decreased breastfeeding duration after adjustment for the mother's infant feeding intention. Method: Pregnant women resident within Avon, UK, expected to give birth between 1 April 1991 and 31 December 1992 were recruited in a longitudinal cohort study. Main outcome measures included maternal infant feeding intention at 32 wk of pregnancy: intention for the first week, intention for the rest of the first month and intention in months 2 to 4. Maternal smoking was defined as any smoking reported at any time during pregnancy. Data on initiation and duration of breastfeeding were based on the questionnaire at 6 mo postpartum, supplemented by data from the 15-mo questionnaire if necessary. Results: Women who smoked during pregnancy had an adjusted odds ratio of 1.5 (95% CI: 1.3 - 1.7) of not breastfeeding at 6 mo compared to non-smokers ( adjusting for maternal age, education and intention). Survival analysis of duration of breastfeeding in the first 6 mo postpartum found that women who intended to breastfeed for less than 1 mo were 78% more likely to stop at any given time than women planning to breastfeed for at least 4 mo, while smokers were 17% more likely to stop breastfeeding than non-smokers.Conclusion: Although women who smoke are less likely to breastfeed their infants than are nonsmoking women, it appears that this is largely due to lower motivation to breastfeed rather than a physiological effect of smoking on their milk supply.
