Data analysis from the 2018 Centers for Disease Control and Prevention Breastfeeding Report Card failed to show improvements in breastfeeding outcomes in Baby-Friendly facilities over statewide breastfeeding initiation programs.
In a pooled analysis of prospective studies, researchers found an increased risk of breast cancer among parous women that persists for more than 20 years after childbirth. Breastfeeding did not modify this pattern.
Breastfeeding for six months or longer cuts the risk of developing type 2 diabetes nearly in half for women throughout their childbearing years, according to results of a long-term observational study.
Breastfeeding is associated with less frequent bacterial infections and with less subsequent obesity. Using antibiotics reduces or removes these favorable effects of breastfeeding, perhaps via alterations in the intestinal microbiota.
