Abstract
Objective: To investigate the effects of perinatal dioxin exposure on the physical development of 5 years old children. Subject and method: 185 pairs of mother-infant living in Bien Hoa (dioxin-contaminated area) and 104 pairs of mother-infant living in Ha Dong (control area) were collected. Dioxin exposure of infants was estimated by the measurement of dioxin concentrations in breast milk of nursing mothers. The height, weight, head circumference and BMI were measured and the associations between these indicators and the levels of dioxin exposure were assessed. Result: The concentrations of dioxin in breast milk of mothers in Bien Hoa were 2-3 times higher than those of mothers in Ha Dong. In both boys and girls, almost of body indicators of Bien Hoa group were significantly higher than those of Ha Dong group. Positive relationships were found between body indexes and dioxin exposure levels. Conclusion: Perinatal exposure to dioxin can affect physical development of 5-year-old children.
