Brazilian national survey data from 1975 to 2008 documents secular trends in breastfeeding practices. The median duration of breastfeeding increased from 2.5 to 11.3 months, and exclusive breastfeeding prevalence for infants under six months rose from 3.1% to 41.0%. The study was authored by Sônia Isoyama Venâncio and reanalyzes seven national surveys using consistent statistical techniques.
