To compare breastfeeding difficulties attributable to the baby and mother/milk and exclusive breastfeeding between a group of late preterm (LP) infants and term infants.
We utilized data from a prospective community-based cohort (n=2977) in Calgary, Alberta, and performed bivariate and multivariable analyses to identify demographic, obstetric, maternal and infant health indicators that were independently associated with term status and breastfeeding outcomes.
Multivariable analyses found that LP status was an independent risk factor for breastfeeding difficulties attributable to the baby (OR 1.72, 95% CI 1.24-2.38), but not for difficulties due to mother/milk (defined as not producing enough milk or having flat or inverted nipples). Among women who were breastfeeding at hospital discharge, mothers of LP infants were less likely to report exclusive breastfeeding at 4 months (OR 0.67, 95% CI 0.46-0.97), after controlling for household income level, mode of delivery and postpartum maternal physical health.
Mothers of LP infants need increased support to establish successful breastfeeding outcomes and to ensure that these infants receive the full benefits of breast milk.
比较婴儿和母亲/奶导致的母乳喂养困难以及纯母乳喂养在一组晚期早产儿（LP）和足月产儿中的差异。
我们利用来自阿尔伯塔省卡尔加里市一项前瞻性社区队列研究（n=2977）的数据，进行了单变量和多变量分析，以确定与足月产儿状态和母乳喂养结果相关的人口统计学、产科、产妇和婴儿健康指标。
多变量分析发现，LP 状态是婴儿母乳喂养困难的独立危险因素（OR 1.72，95% CI 1.24-2.38），但不是母亲/奶导致的困难（定义为产奶不足或乳头扁平或内陷）的独立危险因素。在出院时正在母乳喂养的妇女中，LP 婴儿的母亲在 4 个月时报告纯母乳喂养的可能性较小（OR 0.67，95% CI 0.46-0.97），在控制家庭收入水平、分娩方式和产后产妇身体健康状况后。
LP 婴儿的母亲需要更多的支持，以建立成功的母乳喂养结果，并确保这些婴儿充分受益于母乳。
