Excessive ranges of the stress hormone cortisol throughout the third trimester of being pregnant might enhance speech and language expertise within the first 3 years of a kid’s life, based on analysis offered on the twenty fifth European Congress of Endocrinology in Istanbul.

The staff will subsequent assess whether or not youngsters uncovered to excessive cortisol within the womb usually tend to have greater intelligence quotient (IQ) scores. Apart from the info on maternal cortisol ranges and early language growth, the Odense Youngster Cohort additionally has information on intelligence assessments carried out by youngsters aged 7 years previous. “Early language growth in youngsters is called a predictor for cognitive operate later in life, equivalent to consideration, reminiscence and studying, so we wish to examine whether or not prenatal cortisol publicity can also be related to IQ scores of youngsters aged 7 years previous,” stated Dr Fenger Dreyer.
