According to the American Academy of Pediatrics, infants should be exclusively breastfed for the first 6 months of life followed by breastfeeding with complementary food for up to 2 years of age or beyond. Knowledge of breastfeeding recommendations may greatly influence breastfeeding practices; however, the association between a woman's knowledge of exclusive breastfeeding recommendations and breastfeeding duration is not well explored. This study aims to examine the relationship between knowledge of exclusive breastfeeding recommendations before birth and breastfeeding duration.
Data from the prospective, longitudinal 2005-2007 Infant Feeding and Practices Study II were analyzed (N = 2,935). Knowledge of national breastfeeding recommendations (yes; no) was based on a survey question asking the recommended length of breastfeeding. Breastfeeding duration was reported in weeks and was analyzed as any breastfeeding or exclusive breastfeeding. Cox proportional hazard models were used to obtain crude and adjusted hazard ratios (HRs) and 95% confidence limits (CLs).
Overall, 91.7% of women did not exclusively breastfeed the recommended duration and one in five (21.4%) did not know current breastfeeding recommendations. Women without knowledge of exclusive breastfeeding recommendations had a lower probability of breastfeeding compared with women with knowledge of breastfeeding recommendations. Furthermore, after adjusting for confounders, women without knowledge of exclusive breastfeeding recommendations had 11% higher risk (HR = 1.11; 95% CL = 1.01-1.23) of ceasing breastfeeding at every point in time compared with women who reported knowledge of breastfeeding recommendations while exclusive breastfeeding was not significant.
Findings from this study provide evidence that a mother's knowledge of exclusive breastfeeding recommendations impacts breastfeeding practices. Healthcare providers and public health professionals should educate mothers about breastfeeding.
根据美国儿科学会的建议，婴儿在出生后的前6个月应纯母乳喂养，之后母乳喂养并添加辅食直至2岁或更久。对母乳喂养建议的了解可能会极大地影响母乳喂养行为；然而，女性对纯母乳喂养建议的了解与母乳喂养持续时间之间的关联尚未得到充分研究。本研究旨在探讨产前对纯母乳喂养建议的了解与母乳喂养持续时间之间的关系。
分析了2005 - 2007年前瞻性纵向婴儿喂养与实践研究II的数据（N = 2935）。对国家母乳喂养建议的了解情况（是；否）基于一个询问母乳喂养建议时长的调查问题。母乳喂养持续时间以周为单位报告，并分析为任何形式的母乳喂养或纯母乳喂养。使用Cox比例风险模型来获得粗风险比和调整后的风险比（HRs）以及95%置信区间（CLs）。
总体而言，91.7%的女性未进行建议时长的纯母乳喂养，五分之一（21.4%）的女性不知道当前的母乳喂养建议。与了解母乳喂养建议的女性相比，不了解纯母乳喂养建议的女性进行母乳喂养的可能性较低。此外，在对混杂因素进行调整后，与报告了解母乳喂养建议的女性相比，不了解纯母乳喂养建议的女性在每个时间点停止母乳喂养的风险高11%（HR = 1.11；95% CL = 1.01 - 1.23），而纯母乳喂养情况不显著。
本研究结果提供了证据，表明母亲对纯母乳喂养建议的了解会影响母乳喂养行为。医疗保健提供者和公共卫生专业人员应向母亲们宣传母乳喂养知识。
