Twins have lower risk of suicide than general population

Researchers in Denmark identified 21,653 same sex twins born from 1870 to 1930 and established date and cause of death from 1943 to 1993. They compared suicide rates with the general population.
Twins (both men and women) had a substantially lower suicide rate compared with the general population. This supports the view that strong family ties reduce the risk for suicidal behaviour, say the authors. From British Medical Journal:

Twins have lower risk of suicide than general population

Risk of suicide in twins: 51 year follow up study BMJ Volume 327, pp 373-4

Researchers in Denmark identified 21,653 same sex twins born from 1870 to 1930 and established date and cause of death from 1943 to 1993. They compared suicide rates with the general population.

Twins (both men and women) had a substantially lower suicide rate compared with the general population. This supports the view that strong family ties reduce the risk for suicidal behaviour, say the authors.

The strongest risk factor for suicide is mental illness, and other studies have found mental illness to be slightly more common among twins than among singletons. “This should lead to a higher proportion of twins committing suicide compared with the general population, but our findings show exactly the opposite, further underscoring the importance of strong family ties,” they conclude.
