Lower average height of pedophiles reinforces theory of a biological
TORONTO, Oct. 22 /CNW/ - Height may point to a biological basis for
pedophilia, according to new research released by the Centre for Addiction and
Mental Health (CAMH). The study found that pedophilic males were shorter on
average than males without a sexual attraction to children.
The study, published in Sexual Abuse: A Journal of Research and
Treatment, suggests that pedophiles may have been exposed to pre-birth
conditions that affected their physical development. The researchers observed
this height difference by analyzing the files of over 1,000 men who were
assessed for pedophilia or other sexual disorders between 1995 and 2006 at the
Kurt Freund Laboratory in Toronto, Canada.
A difference in average height is a trait found in other illnesses with
biological links. The average difference in height was two centimeters, which
is similar to the shorter height associated with schizophrenia or Alzheimer's
Further research is necessary, but this finding re-enforces evidence that
pedophilia has a biological cause, possibly related to brain development
"This research does not mean that pedophiles are not criminally
responsible for their behavior," said Dr. James Cantor, CAMH Psychologist and
lead researcher on the study, "but the discovery of biological markers for
pedophilia has important implications for future study and possibly
This study adds to previous research from this team that found pedophiles
have lower IQs, are three times more likely to be left-handed, failed school
grades significantly more frequently, and suffered more head injuries as
The Kurt Freund Laboratory was established in 1968 and remains one of the
world's foremost centres for the research and diagnosis of pedophilia and
other sexual disorders.
