Relationship between breast milk dioxin concentrations and steroid hormone levels in Vietnamese

本研究的目的是通过比较越南喷洒落叶剂的地区和未喷洒落叶剂的地区，阐明母乳中二恶英与血清和唾液中类固醇激素、寄生虫生长之间的关系。研究对象为20 ~ 30岁的母亲和4 ~ 16周龄的子代，每对50对。二恶英浓度与某些甾体激素水平呈U型关系。女孩的生长与二恶英浓度和类固醇激素水平的关系比男孩的强。

The purpose of this study was to clarify the association of dioxin in breast milk and steroid hormone in serum and saliva, primiparae's growth by comparing the defoliant sprayed area and non-sprayed area in Vietnam. The subjects were mother aged between 20 and 30 years old and their primiparae aged between 4 and 16 weeks, each 50 pairs.Almost Dioxin isomer concentrations from sprayed area were higher than non-sprayed area. Dioxin concentrations showed U-shaped relationship with some steroid hormone levels. Girl's growth showed stronger relationship with dioxin concentrations and steroid hormone levels than boy's growth.
