A diagnosis of mental health disorder is associated with up to 15 life years lost (LYLs) compared to the general population, according to a Danish study published in The Lancet.
The population-based cohort study included almost 7.4 million people aged
The study found that mortality rates were higher for people with a mental disorder than for the general population (28.70 deaths vs 12.95 deaths per 1,000 person-years). Additionally, all types of disorders were associated with higher mortality rates, with mortality rate ratios (MRRs) ranging from 1.92 for mood disorders to 3.91 for substance use disorders.
All types of mental disorders were associated with shorter life expectancies, with excess LYLs ranging from 5.42 years for organic disorders in females to 14.84 years for substance use disorders in males.
Most premature mortality was attributable to causes of death related to general medical conditions, including infectious diseases, neoplasms, diabetes, circulatory system diseases and respiratory diseases.
The authors say the findings highlight the need for coordinated care of general medical conditions in those with mental disorders.
