The neurocognitive benefits of breastfeeding that are present in early school-aged children may not extend into adolescence, according to a 16-year follow-up of the Promotion of Breastfeeding Intervention Trial (PROBIT). This follow-up study was published in PLOS Medicine.
A total of 13 557 participants from PROBIT (79.5% of those initially randomized) were examined at age 16 years. Neurocognitive function was assessed in 7 verbal and nonverbal cognitive domains using a computerized, self-administered test. In contrast to earlier findings at age 6.5 years, the scores between groups in adolescence were not significantly different, except for the intervention group’s slightly higher scores for verbal function.
