Breastfeeding: factors associated with the continuation of breastfeeding, the current situation in Japan, and recommendations for further research

There are a number of research reports that address the various advantages that breastfeeding brings to mothers and children, as well as to families and society, and in addition to a number of physically positive effects, breastfeeding has an important role in terms of mental and psychological effects. Ninety-five % of mothers desire to breastfeed, which reflects social acceptance, but the actual breastfeeding rate of the first month after childbirth is 42%, which accounts for about a half of all mothers. Breastfeeding is a natural behavior, but it cannot be performed only by instinct, so mothers discontinue breastfeeding for various reasons. While these reasons for the discontinuation of breastfeeding have been studied in many countries, research regarding the usability of care to support breastfeeding is being conducted in other countries at a level that can be considered evidential, but not yet in Japan. In addition, the current situation is that breastfeeding is strongly promoted but the support provided remains inadequate for mothers who cannot breastfeed, regardless of whatever efforts they make. This article will review several factors associated with the continuation of breastfeeding and the current situation in Japan, with the intention of identifying desirable areas for further research.
