Mortality among people with OCD.

Several mental disorders have consistently been found to be associated with decreased life expectancy, but little is known about whether this is also the case for obsessive-compulsive disorder (OCD). The aim of a new research published in JAMA Psychiatry was to determine whether people who receive a diagnosis of OCD are at increased risk of death. The experts conducted a nationwide prospective cohort study with 30 million person-years of follow-up, using data from Danish longitudinal registers. It has been estimated mortality rate ratios (MRRs), adjusted for calendar year, age, sex, maternal and paternal age, place of residence at birth and somatic comorbidities, to compare people with OCD with the ones without OCD. Of 10.155 people suffering with that disorder, 110 (1.1%) died during the average follow-up of 9.7 years. The risk of death by natural or unnatural causes was significantly higher among individuals with OCD than among the general population. Moreover, after the exclusion of people with comorbid anxiety disorders, depression or substance use disorders, OCD was still associated with increased mortality risk.

Association of bullying behavior at 8 years of age and use of specialized services for psychiatric disorders by 29 years of age.

A research, published on the Jama Psychiatry, aimed to observe the associations between bullying behavior at 8 years of age and adult psychiatric outcomes by 29 years of age. The cross-section was composed of 5034 Finnish children with information about childhood bullying behavior from 8 to 29 years of age: information about bullying, exposure to bullying and psychiatric symptoms were obtained from parents, teachers and child self-reports when children were 8 years of age; use of specialized services for psychiatric disorders from 16 to 29 years of age was obtained from a nationwide hospital register. Among the participants, 4540 (90.2%) did not engage in bullying behavior: of these, 520 (11.5%) had received a psychiatric diagnosis at follow-up; 33 of 166 (19.9%) who engaged in frequent bullying, 58 of 251 (23.1%) frequently exposed to bullying and 24 of 77 (31.2%) who both frequently engaged in and were frequently exposed to bullying had received psychiatric diagnoses. The results showed that exposure to bullying, even in the absence of childhood psychiatric symptoms, is associated with severe adulthood psychiatric outcomes that require treatment in specialized services.
