Analysis of basic conditioning factors in the mother/child affecting breast‐feeding

Purpose : The purpose of this study was to clarify basic conditioning factors affecting the continuation of breast‐feeding until１month after delivery and find parameters for its continuation and the assessment of care need.
Methods : As basic conditioning factors in the mother/child affecting the continuation of breast‐feeding, ５ factors（age, number of children previously cared for, delivery time, bleeding volume at delivery, and birth weight）, which were suggested to affect breast‐feeding by the literature, were analyzed by logistic regression analysis, and the degrees of their influences were calculated. In addition, to evaluate the influences of３factors（absence of breast‐feeding in the last child, smoking habit, and absence of breast-feeding at discharge）, which were major influential factors but had to be deleted in the process of the production of a questionnaire of breast‐feeding limitation factors（Haku, M.２００４）, on the feeding method１ month after delivery, differences were analyzed by Fisher’s direct method and the ▯２ test.
Results : １．Basic conditioning factors affecting the milk feeding method１month after delivery The odds ratio for each factor in the mother/child was１．０３３for age,０．８７２for the number of children previously cared for, １．０１２ for delivery time, １．６５９ for bleeding volume at delivery, and ２．８６１ for birth weight. Bleeding volume at delivery（p＝０．０４２）and birth weight（p＝０．０２１）were significantly correlated with mixed/bottle‐feeding１month after delivery.
２．Three factors affecting breast‐feeding１month after delivery
Mixed/bottle‐feeding１month after delivery was significantly more frequently observed in mothers with the absence of breast‐feeding in the last child（Fisher p＝０．０００６）, a smoking habit（Fisher p＝０．０４）, and the absence of breast‐feeding at discharge（▯２＝７．２８, p＝０．００７）than in those otherwise.
Conclusion : These results suggest that５basic conditioning factors “bleeding volume at delivery ≥５００ml”, “birth weight＜２５,００g”, “absence of breast‐feeding in the last child”, “smoking habit”, and “absence of breast‐feeding at discharge” can be parameters for the assessment of breast‐feeding limitation factors.
