Breastfeeding has immediate and long-term benefits for both maternal and child health. This study examines the association between Baby-Friendly Hospital Initiative (BFHI) experiences and breastfeeding outcomes in the Mountain West region.
A cross-sectional (retrospective secondary data analysis) was performed using the 2016 Pregnancy Risk Assessment Monitoring System (PRAMS) data. The participants were derived from a stratified random sample of 2,013 women living in Utah and Wyoming who recently had a live birth and who were surveyed on BFHI practices. The association between BFHI experiences and breastfeeding duration were assessed using crude and adjusted Poisson regression models, controlling for other BHFI experiences and maternal age, pre-pregnancy BMI, household income, smoking, alcohol, delivery method, and number of days spent in the hospital post delivery.
82.4% and 82.3% of women from Utah and Wyoming, respectively, reported breastfeeding for 2 months or longer. After controlling for other BFHI experiences and potential confounders, the one shared BFHI experience that was associated with breastfeeding for 2 months or longer vs less than 2 months was starting breastfeeding in the hospital (adjusted prevalence ratio [aPR]=1.49, 95% CI (1.12, 1.98) in Utah and aPR=2.03, 95% CI (1.13, 3.64) in Wyoming. Among women in Utah and Wyoming, only 5 of 7 BFHI steps were significant for breastfeeding duration in at least one state.
There is substantial epidemiological support for health benefits to both mother and infant for exclusive breastfeeding to 6 months and prolonged breastfeeding until at least 1-year. Our findings suggest that women who initiate breastfeeding in the hospital may be more likely to breastfeed for a longer duration.
母乳喂养对母婴健康具有即时和长期的益处。本研究探讨了“爱婴医院倡议”(BFHI)经历与美国西部山区母乳喂养结果之间的关联。
使用2016年妊娠风险评估监测系统(PRAMS)数据进行横断面研究(回顾性二次数据分析)。参与者来自犹他州和怀俄明州的2013名近期有活产且接受过BFHI实践调查的女性的分层随机样本。使用粗泊松回归模型和调整后的泊松回归模型评估BFHI经历与母乳喂养持续时间之间的关联,同时控制其他BFHI经历以及产妇年龄、孕前体重指数、家庭收入、吸烟、饮酒、分娩方式和产后住院天数。
犹他州和怀俄明州分别有82.4%和82.3%的女性报告母乳喂养2个月或更长时间。在控制其他BFHI经历和潜在混杂因素后,与母乳喂养2个月或更长时间而非少于2个月相关的一项共同BFHI经历是在医院开始母乳喂养(犹他州调整患病率比[aPR]=1.49,95%置信区间CI;怀俄明州aPR=2.03,95%CI(1.13,3.64))。在犹他州和怀俄明州的女性中,7项BFHI步骤中只有5项在至少一个州对母乳喂养持续时间具有显著意义。
有大量流行病学证据支持纯母乳喂养至6个月并延长母乳喂养至至少1年对母婴健康有益。我们的研究结果表明,在医院开始母乳喂养的女性可能更有可能进行更长时间的母乳喂养。
