Analysis of the mammary gland structure involved in lactation and factors associated with breast-feeding continuation

本研究的目的是阐明影响从分娩到分娩后3个月持续母乳喂养的因素。我们认为，本研究结果可为有效支持母乳喂养提供依据，实现母亲“以母乳哺育子女”的愿望。结果1.以下3大类22项是影响母乳喂养持续到产后1个月的因素1）影响母乳喂养的社会心理因素：14个项目“母乳喂养的第一次育儿”、“放弃经验”、“由于理想中的孩子和实际孩子之间的差异而造成的适应不良”、“与孩子一起生活的经验不足”、“精力不足”、“对母乳喂养缺乏兴趣或愿望”，“不适当的目标/取向和价值观”、“不适当的决策”、“家庭成员或其他人的干扰”、“不利于母乳喂养的生活环境”、“家庭成员或家中的危急情况”、“乳房问题”、“缺乏支持”和“产妇忧郁”。2）影响母乳喂养的乳房形态因素：3项“乳房形态异常（扁平乳头、内陷乳头、大乳头直径[大于或等于] 17 mm）"、“乳头裂隙”、“乳腺组织厚度[小于或等于] 21 mm”。3）影响母乳喂养的母/儿背景因素：5项“分娩时出血量[大于或等于] 500 ml”、“出生体重< 2,500 g”、“最后一个孩子没有母乳喂养”、“吸烟习惯”、2.出院时母乳喂养可能是母乳喂养持续到产后3个月的指标。结论根据这些结果，我们打算开发一个评估工具，以支持继续母乳喂养。

The purpose of this study was to clarify factors affecting breast-feeding continuation from delivery until 3 months after delivery. We consider that the results of this study may provide the basis of effective support for breast-feeding, allowing the realization of mothers' wish for "childcare by breast-feeding".Results1.The following 22 items in 3 categories were factors affecting the continuation of breast-feeding until 1 month after delivery1)Psychosocial factors affecting breast-feeding : 14 items"Fist childcare by breast-feeding", "resignation from experience", "maladjustment due to differences between the idealize child and the actual child", "insufficient living experience with the child", "insufficient energy", "lack of interest in or wish for breast-feeding", "inappropriate goals/orientations and values", "inappropriate decision-making", "disturbance by family members or others", "living situations not conducive to breast-feeding", "critical situations of family members or at home", "breast troubles", "lack of support", and "maternity blues".2)Breast morphological factors affecting breast-feeding : 3 items"Breast morphological abnormalities (flat nipples, inverted nipples, and large nipples 【greater than or equal】 17 mm in diameter)", "nipple fissures", and "mammary gland tissue thickness 【less than or equal】 21 mm".3)Background factors in the mother/child affecting breast-feeding : 5 items"Bleeding volume at delivery 【greater than or equal】 500 ml", "birth weight < 2,500 g", "absence of breast-feeding in the last child", "smoking habit", and "absence of breast-feeding at discharge".2.Breast-feeding at discharge may be an indicator of the continuation of breast-feeding until 3 months after delivery.ConclusionBased on these results, we intend to develop an assessment tool for support for the continuation of breast-feeding.
