Abstract

Human milk is the ideal source of nutrition for infants; however, adherence to breastfeeding recommendations is suboptimal and availability of Canadian breastfeeding data are limited. Using the 2017-2018 Canadian Community Health Survey Public Use Microdata File (Maternal Experiences Module, n = 5558, weighted n = 1 669 462) we computed breastfeeding indicators and explored sociodemographic, health, and geographical predictors of breastfeeding with univariate logistic regression models. Nationally, of all participants who gave birth in the preceding 5 years, 91% initiated breastfeeding, 43% exclusively breastfed to ≥5 months and 35% to ≥6 months, 56% reported any breastfeeding at ≥6 months, and 31% reported breastfeeding at ≥12 months. Breastfeeding cessation was most commonly attributed to insufficient milk supply (25%), but reasons differed significantly by breastfeeding duration. Breastfeeding initiation, exclusivity for ≥5 months, and extended breastfeeding ≥12 months all differed by geographic region, and by most sociodemographic and health characteristics. Positive breastfeeding outcomes were highest in British Columbia, and lowest in Quebec and the Atlantic region, and generally higher if caregivers had recently immigrated to Canada, were married, were >30 years of age, were not White, were nonsmoking, had completed postsecondary education, and had an annual household income >$40 000. These disparities indicate the need for tailored, equitable approaches to breastfeeding support, and continued regional monitoring of breastfeeding outcomes.

加拿大的母乳喂养:2017-2018年加拿大社区健康调查的开始、排他性和延续的预测因素
母乳是婴儿理想的营养来源;然而,坚持母乳喂养建议是次优的,加拿大母乳喂养数据的可用性是有限的。利用2017-2018年加拿大社区卫生调查公共使用微数据文件(产妇经验模块,n = 5558,加权n = 1 669 462),我们计算母乳喂养指标,并利用单变量logistic回归模型探讨母乳喂养的社会人口、健康和地理预测因素。在全国范围内,在过去5年内分娩的所有参与者中,91%开始母乳喂养,43%纯母乳喂养至≥5个月,35%至≥6个月,56%报告母乳喂养≥6个月,31%报告母乳喂养≥12个月。停止母乳喂养最常见的原因是母乳供应不足(25%),但原因因母乳喂养时间长短而有显著差异。开始母乳喂养、纯母乳喂养≥5个月以及延长母乳喂养≥12个月的时间均因地理区域以及大多数社会人口统计学和健康特征而异。母乳喂养阳性结果在不列颠哥伦比亚省最高,在魁北克和大西洋地区最低,如果照顾者最近移民到加拿大,已婚,年龄>30岁,非白人,不吸烟,完成高等教育,家庭年收入> 4万美元,则母乳喂养阳性结果通常更高。这些差异表明,需要采取有针对性的、公平的母乳喂养支持方法,并继续对母乳喂养结果进行区域监测。
