title: Psychiatric disorders and use of mental health services by Ontario women.
abstract: OBJECTIVE
  To describe the lifetime prevalence of selected psychiatric disorders in Ontario women and to compare these estimates with use of mental health resources.
  
  
  METHODS
  We obtained data from a survey of 3062 Ontario women, aged 25 to 74 years, who participated in the Women's Health Study. A 5-item scale assessed lifetime prevalence of 5 psychiatric disorders (anxiety, depression, posttraumatic stress disorder [PTSD], obsessive-compulsive disorder [OCD], and anorexia [AN] or bulimia [BN]). We assessed use of mental health services by comorbidity. We employed stratified random sampling to select study subjects. Prevalence estimates were weighted and 95%CIs were obtained using Taylor linearization techniques (1).
  
  
  RESULTS
  Nearly 30% of those surveyed reported at least 1 of the disorders studied. The most common were depression (27%) and anxiety (21%). Lifetime prevalence of PTSD, OCD, and AN or BN were 10.7%, 6.1%, and 3.9%, respectively. Successively younger birth cohorts displayed an increase in prevalence and a decrease in onset-age for all disorders. "Ever" use of mental health services was higher for women with 3 or more comorbid disorders (65%) than for those with no disorder (9.8%), or only 1 disorder (51.4%).
  
  
  CONCLUSIONS
  The results of this study highlight the need to conduct more research into the reasons for the low rates of professional service use, especially for women with high comorbidity. They also highlight the need to understand the phenomenon underlying the possibly increasing rates of disorders in younger birth cohorts, so that outreach strategies can be modified to accommodate differences in younger women.
