Background

The Global Burden of Disease Study 2010 GBD 2010 identified mental and substance use disorders as the 5th leading contributor of burden in 2010, measured by disability adjusted life years DALYs. This estimate was incomplete as it excluded burden resulting from the increased risk of suicide captured elsewhere in GBD 2010-s mutually exclusive list of diseases and injuries. Here, we estimate suicide DALYs attributable to mental and substance use disorders.

Methods

Relative-risk estimates of suicide due to mental and substance use disorders and the global prevalence of each disorder were used to estimate population attributable fractions. These were adjusted for global differences in the proportion of suicide due to mental and substance use disorders compared to other causes then multiplied by suicide DALYs reported in GBD 2010 to estimate attributable DALYs with 95% uncertainty.

Results

Mental and substance use disorders were responsible for 22.5 million 14.8–29.8 million of the 36.2 million 26.5–44.3 million DALYs allocated to suicide in 2010. Depression was responsible for the largest proportion of suicide DALYs 46.1% 28.0%–60.8% and anorexia nervosa the lowest 0.2% 0.02%–0.5%. DALYs occurred throughout the lifespan, with the largest proportion found in Eastern Europe and Asia, and males aged 20–30 years. The inclusion of attributable suicide DALYs would have increased the overall burden of mental and substance use disorders assigned to them in GBD 2010 as a direct cause from 7.4% 6.2%–8.6% to 8.3% 7.1%–9.6% of global DALYs, and would have changed the global ranking from 5th to 3rd leading cause of burden.

Conclusions

Capturing the suicide burden attributable to mental and substance use disorders allows for more accurate estimates of burden. More consideration needs to be given to interventions targeted to populations with, or at risk for, mental and substance use disorders as an effective strategy for suicide prevention.
