Wojcicki JM, et al. Early exclusive breastfeeding and maternal attitudes towards infant feeding in a population of new mothers in San Francisco, California. Breastfeed Med. Feb 2010;5(1):9-15.
This study investigated the frequency of exclusive breastfeeding in the early postpartum period, maternal attitudes toward breastfeeding, and WIC Program participation status in a population of mothers at two San Francisco hospitals. The results showed that a higher percentage (79.8%) of the sample was exclusively breastfeeding at 1 to 4 days postpartum. There were no significant differences in the rates of formula or mixed feeding, by WIC participant status. Independent risk factors for formula or mixed feeding at 1 to 3 days postpartum included Asian/Pacific Islander ethnicity. Being a college graduate was associated with a decreased risk of formula or mixed feeding.
