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

本研究的目的是通过对越南落叶剂喷洒区和未喷洒区进行比较，阐明母乳中二恶英、血清和唾液中类固醇激素与初产妇生长的关系。研究对象是年龄在20到30岁之间的母亲和她们4到16周的初产妇，每对50对。喷施区二恶英异构体浓度几乎高于未喷施区。二恶英浓度与某些类固醇激素水平呈u型关系。与男孩相比，女孩的生长与二恶英浓度和类固醇激素水平的关系更强。

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.
