Women need to relax – Male fetuses ignore their stressed-out mothers – health – 20 July 2010 – New Scientist

July 20

Baby girls born to women with moderate to severe asthma had higher levels of cortisol in their cord blood – an average of 245 millimoles per litre – compared with girls born to controls and mildly asthmatic women, who averaged 202 and 209 millimoles per litre respectively.

However, no difference in cortisol levels was observed in baby boys born to either group.

The team also observed that 22.5 per cent of girls born to asthmatic women were small for their gestational age, meaning they were among the lightest 10 per cent of all babies born worldwide. But just 9.5 per cent of girls born to healthy women fell into this group. Again, no difference was observed in boys from either group.
