Maternal stress hormones and maternal smoking increase daughter's risk of nicotine dependence
Date:1/9/2014

others participated, where their hormone levels (cortisol and testosterone) were measured during pregnancy and their smoking status was recorded. Their children, 649 of whom were daughters and 437 of whom were sons, were interviewed as adults and their smoking status was also recorded.

The findings revealed that in female but not male offspring, elevated prenatal cortisol exposure and exposure to maternal smoking during pregnancy were associated with increased rates of nicotine dependence as adults. No links were found between elevated prenatal testosterone exposure and adult nicotine dependence. There were also no findings among male offspring.

"Our findings highlight the particular vulnerability of daughters to long-term adverse outcomes following maternal stress and smoking during pregnancy. We don't yet know why this is, but possible mechanisms include sex differences in stress hormone regulation in the placenta and adaptation to prenatal environmental exposures," added Stroud. "Also, cortisol and nicotine may affect developing male and female brains differently. Furthermore, if daughters of smoking mothers are more likely to grow up nicotine dependent, the result is dangerous cycle of intergenerational transmission of nicotine addiction."

"These new data may help us to focus our attention on individuals at greatest risk for later smoking," said Dr. John Krystal, Editor of Biological Psychiatry. "It is interesting that female, but not male, offspring seemed to be at greatest risk. Sex differences in the vulnerability to smoking are important and merit further study."
