Study Shows Association, but not Causation, between Breastfeeding Rates and Legislation in the United States
A study published in the October 2008 edition of the American Journal of Public Health found state variations in breastfeeding initiation and duration, where western and northwestern states had the highest rates. Additionally, researchers found that breastfeeding initiation rates were highest in states with multiple pieces of legislation supportive of breastfeeding and lowest among states with no such legislation.
