Suicide: intelligence matters in Sweden
Swedish men who score lower in intelligence tests at age 18 are more likely to commit suicide later in life than those with higher scores. Following a cohort of 987 308 men for five to 26 years, Gunnel and colleagues (p 167) found that the risk of suicide decreased by 12% (95% confidence interval 10% to 14%) for each additional unit scored in the test. Parents' socioeconomic status influenced the results only slightly, and poorly performing offspring of well educated parents were at greatest risk.
