| Research Abstract |
In a dioxin hot spot in Danang, Vietnam, we followed up 230 newborns for 4 months, 1 year and 3 years after birth. Infants whose maternal breast milk contained higher dioxins showed lower neurodevelopmental scores including not only cognitive and motor but also social emotional scales tested by Bayley scales, suggesting that dioxin exposure may influence on social interactions. Although maternal daily dioxin intake was low, food pattern of fish and egg were related to levels of dioxins in breast milk.
