Japanese mothers' breastfeeding knowledge and attitudes assessed by the Iowa Infant Feeding Attitudes Scale.

This study describes Japanese mothers' knowledge and attitudes towards breastfeeding using the Iowa Infant Feeding Attitudes Scale (IIFAS). A cross-sectional survey of 1,612 mothers was conducted in Japan in 2007. The participants were recruited at the free health checks conducted for infants at 18 months of age. The survey was self-administered using the Japanese version of the IIFAS. Descriptive statistics were used to summarise sample characteristics and IIFAS score followed by multiple logistic regression to identify association between total IIFAS score and breastfeeding duration. While the IIFAS showed that the majority recognized some benefits of breastfeeding, their overall knowledge and attitudes towards breastfeeding were neutral and more positive towards the use of infant formula. It is important to provide accurate prenatal education that focuses on methods and long-term benefits of infant feeding to mothers, family and health professionals.
