Urinary iodine excretion as a predictor of the iodine content of breast milk.
Endemic goitre has re-emerged in Thailand. This is particularly dangerous for children since iodine deficiency disorders (IDDs) might negatively influence their intellectual and mental development. In order to assess the situation, the iodine content of breast milk was determined and a method is proposed on how to monitor IDDs in lactating mothers later on. Seventy-five lactating women aged from 15 to 45 years, from 12 villages of 3 districts, namely Chumpae. Srichompu and Pupaman within the mountainous areas of Khon Kaen province, Northeast of Thailand were investigated. The breast milk from 46.7 per cent of mothers was found to be below recommended standards. In addition, 52.0 per cent of the women investigated had low urinary iodine excretion. The risk of women with low iodine excretion was 15 fold higher in comparison to women with sufficient iodine excretion to provide breast milk for their babies with insufficient iodine content. It is concluded that urinary iodine excretion can be used to monitor the IDDs in lactating mothers.
