Stress tied to smaller babies

Stressed-out pregnant women may carry smaller-than-average babies, a new study finds.

Stressed-out pregnant women may carry smaller-than-average babies, a new study finds.

In findings published in the September-October issue of Psychosomatic Medicine, researchers from the University of Miami School of Medicine studied 98 women who were 16 to 29 weeks pregnant.

The women completed questionnaires that measured their levels of distress from daily hassles, depression and anxiety. The women also underwent ultrasounds to measure their foetuses, and they provided urine samples to measure levels of stress-linked hormones such as cortisol and norepinephrine.

The researchers found that the foetuses of the mothers with higher rates of depression, anxiety and stress weighed less and were smaller than average.

Cortisol may transmit stress
In addition, cortisol levels were linked to the weight of the foetus, indicating that cortisol may be a potential mechanism for transmitting a mother's stress to her unborn baby.

"One of the things this research highlights is that if you are pregnant and under extreme amounts of stress or feeling depressed, you should talk with your doctor about ways of treating these conditions during pregnancy," study author Miguel A. Diego said in a prepared statement. – (HealthDayNews)
