Me: I found this study which linked to small babies to adult suicide rates to be very interesting. The biological answer that is stated is over the fact that smaller babies haveve less serotonin, which contributes to impulsivity, agression, and suicidal behavior. It seems babies which are born either shorter or lighter than their counter parts are both at risk to suicide. However, that is not all. Short stature in adulthood also increased the suicide tendency, which makes perfect sense, where they were smaller as a baby or average as a baby. It seems no matter how we view it, smaller people just have higher rates of suicide attempts. Obviously there is a social and emotional challenge associated with small stature and I believe completely that anyone who has insecurities with their small stature should seek comfort and help from someone to reduce the risks of suicidal behavior.

Short Male Babies Have More Than Double The Risk Of Violent Suicide Attempts, Study Suggests
ScienceDaily (Jan. 18, 2008) — Short male babies run more than double the risk of a violent suicide attempt as an adult, suggests a new study. Catch up growth during childhood does not lessen the impact of short stature at birth, the research shows.
(Me: That is very interesting that catch-up growth seems to have no effect so it is more than just social or emotional but biological in nature)
The findings are based on almost 320,000 Swedish men out of a total of more than 713,000 people all born between 1973 and 1980. Using national registers, they were tracked from birth to the date of attempted suicide, death, emigration, or the end of 1999, whichever came first.
Short babies of less than 47 cm in length, were more likely to attempt suicide as adults, no matter what height they reached in adulthood, compared with normal length babies. Short birth length also more than doubled the risk of a violent suicide attempt as opposed to a non-violent one.
A violent suicide attempt was defined as hanging, the use of a firearm or knives, jumping from a height or in front of vehicles, and drowning.
Short stature in adulthood also boosted the risk.
Men who were normal length babies, but who were short in adult life were 56% more likely than tall men to attempt to take their own lives. The taller a man was, the less likely he was to attempt suicide, the findings showed.
Men who were born underweight (under 2500 g), but who reached normal height were more than 2.5 times as likely to make a violent suicide attempt.
And those who were born prematurely, and therefore short and underweight, were more than four times as likely to attempt violent suicide as those born after 38 to 40 weeks of pregnancy.
The authors suggest that the brain chemical serotonin may be key. It is crucial to brain development and low levels are important in impulsivity, aggression, and suicidal behaviour. Serotonin levels may be affected by premature birth and other factors restricting growth in the womb, they add.
This study, Fetal and childhood growth and the risk of violent and non-violent suicide attempts: A cohort study of 318,953 men, is published in the Journal of Epidemiology and Community Health.
