In Canada, 91% of all mothers initiate breastfeeding, but 40-50% stop by 6 months and only 34% breastfeed exclusively for 6 months, with lower rates among socially and/or economically vulnerable women. The Canada Prenatal Nutrition Program (CPNP) aims to support breastfeeding among vulnerable women, but there is no formal framework or funding for sites to integrate proactive postnatal breastfeeding support. This research aimed to i) describe infant feeding practices among clients of one Toronto CPNP site using charitable funds to offer a lactation support program (in-home lactation consultant visits, breast pumps); ii) determine whether breastfeeding outcomes at 6 months differ based on maternal sociodemographics and food insecurity; and iii) assess utilization of the lactation support program.
Infant feeding practices were collected prospectively at 2 weeks, 2, 4 and 6 months postpartum via telephone questionnaires (n = 199). Maternal sociodemographics were collected at 2 weeks and food insecurity data at 6 months postpartum. Program monitoring records were used to determine utilization of the lactation support program.
Ninety-one percent of participants were born outside of Canada; 55% had incomes below the Low-Income Cut-Off; and 55% reported food insecurity. All participants initiated breastfeeding, 84% continued for 6 months and 16% exclusively breastfed for 6 months. Among breastfed infants, ≥76% received vitamin D supplementation. Approximately 50% of infants were introduced to solids before 6 months. Only high school education or less and food insecurity were associated with lower breastfeeding rates. Overall, 75% of participants received at least one visit with a lactation consultant and 95% of these received a breast pump.
This study provides initial evidence that postnatal lactation support can be delivered within a CPNP site, with high uptake by clients. While all participants initiated breastfeeding and 84% continued for 6 months, adherence to the recommended 6 months of exclusive breastfeeding was low. Further research is needed to better understand the barriers to exclusive breastfeeding and how to support this practice among vulnerable women.

在加拿大,91%的母亲都会开始母乳喂养,但有 40-50%的母亲会在 6 个月时停止母乳喂养,只有 34%的母亲会在 6 个月内纯母乳喂养,社会和/或经济弱势群体中的这一比例更低。加拿大产前营养计划(CPNP)旨在支持弱势群体中的母乳喂养,但没有为各站点提供正式框架或资金来整合积极的产后母乳喂养支持。本研究旨在:i)描述多伦多一个 CPNP 站点的客户的婴儿喂养情况,该站点使用慈善资金提供母乳喂养支持计划(上门哺乳顾问访问、吸乳器);ii)确定 6 个月时的母乳喂养结果是否因产妇的社会人口统计学和粮食不安全状况而异;iii)评估母乳喂养支持计划的利用情况。
通过电话问卷调查,在产后 2 周、2、4 和 6 个月时前瞻性收集婴儿喂养情况(n=199)。在产后 2 周时收集产妇的社会人口统计学数据,在产后 6 个月时收集粮食不安全数据。使用方案监测记录来确定母乳喂养支持计划的利用情况。
91%的参与者出生在加拿大以外;55%的人收入低于低收入线;55%的人报告粮食不安全。所有参与者都开始母乳喂养,84%的人持续母乳喂养 6 个月,16%的人纯母乳喂养 6 个月。在母乳喂养的婴儿中,≥76%的婴儿接受了维生素 D 补充剂。大约 50%的婴儿在 6 个月之前开始添加固体食物。只有高中学历或以下和粮食不安全与较低的母乳喂养率有关。总体而言,75%的参与者至少接受过一次哺乳顾问的访问,其中 95%的人接受了吸乳器。
本研究初步证明,产后哺乳支持可以在 CPNP 站点提供,客户的接受度很高。虽然所有参与者都开始了母乳喂养,84%的人持续母乳喂养 6 个月,但坚持推荐的 6 个月纯母乳喂养的比例很低。需要进一步研究以更好地了解纯母乳喂养的障碍以及如何在弱势群体中支持这一做法。该研究在 clinicaltrials.gov 注册,注册号为 NCT03400605。
