TOPLINE:
Obsessive-compulsive disorder (OCD) is linked to a twofold increased risk for all-cause mortality and a heightened risk for death from both natural and unnatural causes, a new study showed.
METHODOLOGY:
- Investigators studied a population-based cohort (58% female) of 61,378 people with OCD and 613,780 unaffected individuals from several Swedish population registers and a sibling cohort of 34,085 people with OCD (58% female) and 47,874 unaffected full siblings (48% female).
- The median 8.1-year follow-up and median age at first diagnosis of OCD were 27 years.
- The researchers used Cox proportional hazard models, adjusting for birth year, sex, county, country of birth (Sweden vs abroad), and sociodemographic variables.
TAKEAWAY:
- (adjusted hazard ratio [aHR], 1.82; 95% CI, 1.76-1.89), an almost threefold higher risk for mortality due to unnatural causes (aHR, 3.30; 95% CI, 3.05-3.57), and a higher risk for mortality due to natural causes (aHR, 1.31; 95% CI, 1.24-1.37).
- Of all the unnatural causes of death, suicide was most common (hazard ratio [HR], 4.90; 95% CI, 4.40-5.46), followed by accidents (HR, 1.92; 95% CI, 1.68-2.19).
- Similar results were found in the sibling comparison, where the HR of all-cause mortality was 1.85 (95% CI, 1.67-2.03), death from natural causes was 1.51 (95% CI, 1.35-1.68), and death from unnatural causes was 3.10 (95% CI, 2.52-3.80).
- Natural causes of death that were higher in the OCD vs non-OCD cohort included endocrine, nutritional, and metabolic diseases; mental and behavioral disorders; and diseases of the nervous, circulatory, respiratory, digestive, and genitourinary systems.
IN PRACTICE:
“Better surveillance, prevention, and early intervention strategies should be implemented to reduce the risk of fatal outcomes in people with OCD,” the authors wrote.
SOURCE:
Lorena Fernández de la Cruz, PhD, of Karolinska Institutet, Solna, Sweden, led the study, which was published online on January 17 in the British Medical Journal.
LIMITATIONS:
The study does not establish causality. Registry data used by the investigators only included diagnoses made in specialist care and may not have included diagnoses made in other settings. It is also unclear whether the findings, derived from a Swedish population, can be generalized to other populations, health systems, and medical practices.
DISCLOSURES:
The study was funded by the Swedish Council for Health, Working Life and Welfare, Region Stockholm, the Swedish Society of Medicine, and Karolinska Institutet. Dr. de la Cruz received royalties for contributing articles to UpToDate and Wolters Kluwer Health and for editorial work from Elsevier outside the submitted work.
