New method: Research team analyzes stress biology in babies
Date:8/28/2012

After waking up, the concentration of the stress hormone cortisol in saliva rises considerably; this is true not only for grown-ups but for babies as well. A research team from the Ruhr-Universitt Bochum and from Basel has reported this finding in the journal Psychoneuroendocrinology. "This gives us a new, non-invasive and uncomplicated possibility to already research the activity of the stress system during infancy," Prof. Dr. Gunther Meinlschmidt, of the Clinic of Psychosomatic Medicine and Psychotherapy at the LWL University Hospital of the RUB, said. The information not only open doors to the pursuit of as-yet unresolved research inquiries, but could also be used in the future to diagnose illnesses in the hormone-producing organs, such as the adrenal gland, of infants.

Testing stress hormones: easy with grown-ups, hard with babies

Scientists usually test the stress hormones of grown-ups by placing test subjects in an experiment under stress-inducing conditions. Since a similar practice is, for ethical reasons, unthinkable to use with babies, it is rather more difficult to find out how well-developed their stress systems are. The German-Swiss research team circumvented this problem by observing a naturally occurring "stress situation" waking up. The cortisol-concentration in grown-ups rises after they wake up, presumably to prepare the body for the requirements of the day. At what age this cortisol-reaction develops has long been unclear.

Cortisol levels rise in babies upon waking up

Data from 64 newborns and infants between the ages of three weeks and six months were used in the study. On two days the infants' parents had their children suck on a small cotton swab at home, once right after waking up and once half an hour later. Through this saliva, the scientists determined the cortisol-concentration. The cortisol amount rose considerably after the infants awoke in 63 % of cases. Neither the hour th
