Swedish researchers say short men may have a higher risk of suicide.

"We found a twofold higher risk of suicide in short men than tall men," they write in the American Journal of Psychiatry.

Of course, short men can live healthy, rewarding lives with no suicidal designs. Tall men and those of average height can also commit suicide.

Researchers working on the study included Finn Rasmussen, MD, PhD. Rasmussen is an associate professor in the public health sciences department of Sweden's Karolinska Institute.

Swedish Suicide Study

Rasmussen's study included nearly 1.3 million Swedish men born from 1950 to 1981. Their height at age 18-19 was noted. That data came from Sweden's military records. Their average height back then was about 5 feet 9 inches, write the researchers.

The men were followed for an average of 15 years. During that time, they had 3,075 suicides.

"Taller men had a much lower risk of suicide than shorter men," write the researchers.

They only focused on suicide risk among men aged 18-49. The results can't be applied to older men or to women, write the researchers.

Researchers' Views

The pattern didn't seem to stem from socioeconomic or prenatal influences, the researchers write.

The results also didn't change much when the researchers excluded men with psychiatric diagnoses at the time of military conscription.

Marital status didn't make much difference, either.

Low weight gain in infancy might be a risk factor for adult suicide in adult life, write the researchers. So could impaired childhood growth due to psychological stress and disrupted family life, they report.

Stigma of Shortness?

Short children may suffer stigmatization and discrimination, write the researchers.

But they didn't have information on childhood intelligence or whether the men were teased or traumatized as children because of their height.

The possible influence of unemployment, relationship breakdown, or mental illness couldn't be fully assessed, write the researchers.

But they did check alcohol-related deaths and deaths of undetermined cause.

Stronger ties were seen with alcohol-related deaths. That "suggest[s] that substance misuse may contribute to the observed patterns," write the researchers.
