Saliva Anomaly in Juvenile Delinquents
article, sourced to "The Washington Post" appeared in "The
West Australian" Newspaper, Monday Jan 31 '00, TODAY section, p, 13:
Boys who are highly aggressive have significantly lower levels of a stress hormone in their saliva, which might indicate a possible biological basis of antisocial behaviour.
Keith McBurnett, of the University of Chicago, and colleagues studied 38 boys aged 7 to 12 who had a history of behaviour problems. The researchers took saliva samples twice over a four year period to measure the amount of the stress hormone cortisol.
Boys with a proclivity towards violence had significantly lower levels of cortisol, the researchers say in the January issue of the Archives of General Psychiatry.
Cortisol is normally released in response to fear, such as fear of punishment for misbehaviour. Low levels, the researchers say, may indicate the boys do not fear the possible consequences of their actions.
There would appear to be a possibility of a link between the observations of this University of Chicago research team and Hafer's observations. The findings in both cases concern anomalies in the saliva of groups of children. It is a well-recognised feature of ADHD behaviour that children do not appear to fear the consequences of their actions. Hafer also claims that people affected by phosphate would be at significantly greater risk of delinquent, violent and criminal behaviour.
