(英) Factors associated with the discontinuation of breastfeeding until 3 months after delivery

(日) Study Purpose : The purpose of this study was to calculate the degree of the influences of factors affecting the discontinuation of breastfeeding until 1 month after delivery on that until 3 months after delivery, and to identify indicators of the discontinuation of breastfeeding until3months. Methods : The subjects were 60 mothers who delivered a single infant and initiated breastfeeding in an early puerperal stage after full-term vaginal delivery. As possible indicators of breastfeeding until 3 months after delivery, 3 breast morphological factor variables(``nipple morphological abnormalities : flat nipples, true inverted nipples, and large nipples ≥17 mm in diameter'', ``nipple fissures'', and ``mammary gland tissue thickness ≤21 mm'')and5factors (bleeding volume at delivery, birth weight, the absence of breastfeeding in the last child, a smoking habit, and the absence of breastfeeding at discharge)were surveyed. The 8 factors were surveyed at the time of puerperal discharge. The continuation of breastfeeding 3 months after delivery was ascertained by telephone. The degree of the influences of each factor on the milk feeding form was analyzed by Fisher's exact method and logistic regression analysis. Results and conclusion Factors affecting the milk feeding form 3 months after delivery Among the 8 possible factors leading to the discontinuation of breastfeeding, the absence of breastfeeding at discharge(Fisher p＝0．003)alone compared with its presence resulted in mixed/ bottlefeeding 3 months after delivery. The odds ratio of each factor in the mother/child was 1．931 for the thickness of mammary gland tissue, 1．677 for bleeding volume at delivery, 2．502 for the absence of breastfeeding in the last child, and 7．337 for the absence of breastfeeding at discharge. By logistic regression analysis, only the absence of breastfeeding at discharge was correlated with mixed/bottlefeeding 3 months after delivery(odds ratio, 7．337 ; p＝0．017). These results suggest that the absence of breastfeeding at discharge is an indicator of the discontinuation of breastfeeding until 3 months after delivery.
