OBJECTIVE: Previous studies have found associations between poor
fetal and infant growth and the risk of suicide. The authors’ goal was
to investigate the association between height—a measure of childhood
growth—and suicide risk.
METHOD: The authors conducted a record
linkage study of the birth, conscription, mortality, family, and census
register data of 1,299,177 Swedish men followed from age 18 to a maximum
of age 49.
RESULTS: There were 3,075 suicides over an average
follow-up period of 15 years. There was a strong inverse association
between height and suicide risk. In fully adjusted models, a 5-cm
increase in height was associated with a 9% decrease in suicide risk.
strong inverse association between height and suicide may signify the
importance of childhood exposure in the etiology of adult mental
disorder or reflect stigmatization or discrimination encountered by
short men in their adult lives.
Watch some goof spin this into, "short men are just innately depressed and insecure, so they kill themselves. See? That's why tall men are better!"
I for one lean towards the "discrimination causes suicide" theory, because that's obvious.
P.S. Yeah, this study is about a correlation, not a definitive cause. Don't worry, I know. Very strong percentages though. Researchers also ruled out factors such as socioeconomic status, psychiatric diagnoses, etc. More here:
