Overview
Once believed to be rare, OCD was found to have a lifetime prevalence of 2,300 per 100,000 (2.3%) of the overall population. The twelve month prevalence of OCD is 1,200 per 100,000 (1.2%) of the overall population.[1][2] Discovery of effective treatments and education of patients and health care providers have significantly increased the identification of individuals with OCD. International studies have shown a similar incidence and prevalence of OCD worldwide.
Epidemiology and Demographics
- The lifetime prevalence of obsessive compulsive disorder is 2,300 per 100,000 (2.3%), though many cases of OCD go under-treated in primary care settings.[2][3]
- The twelve month prevalence of obsessive compulsive disorder is 1,200 per 100,000 (1.2%) of the overall population.[1]
- The lifetime prevalence of OCD is higher for individuals who have not graduated high school (3.4%) than for those who have (1.9%). However, the lifetime prevalence is higher for those who graduate with a college degree (3.1%) than for those who have minimal college background (2.4%).
- The onset of OCD averages at 19.5 years old, but usually ranges from the late teenage years until the mid-20s in both sexes, however the age of onset for males tends to be younger in males than that in females.[4]
- A 2008 study suggests OCD symptoms in Japanese patients are similar to those found in Western countries, proving that, contrary to prior hypotheses, the disorder transcends culture and geography.[5]
- It has been alleged that sufferers are generally of above-average intelligence, as the disorder necessitates complicated thinking patterns.
