Effects of environmental exposure of dioxins on infant development of social emotional behavior

在越南岘港的一个二恶英热点地区，我们对230名新生儿进行了4个月、1年和3年的随访。婴儿的母亲母乳中含有较高的二恶英表现出较低的神经发育评分，不仅包括认知和运动，但也社会情感量表测试贝利量表，表明二恶英暴露可能会影响社会交往。虽然母亲每日的二恶英摄入量较低，但鱼和蛋的食物模式与母乳中的二恶英水平有关。

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.
