9.1 Countrywide Systematic Reviews: Summarizing National Scientific Literature on Mental Health for Children and Youth

of this Symposium is to present new data from a number of epidemiological studies globally that use new methods, sampling frames, and analytic methods to build upon the work of the first generation of psychiatric epidemiological studies.Methods: Four presentations will focus on data from Ontario, Brazil, Greece, and the United States, and data from the Global Burden of Disease database.Each presentation will focus on innovations in sampling, measurement, data analysis, and data synthesis to go beyond simple estimates of prevalence and associations with risk and protective factors.Results: The results across the 4 presentations support the high prevalence of mental disorders among children and youth as well as highlighting important inequities across specific populations.Conclusions: A developmentally sensitive approach to estimating prevalence and morbidity associated with mental disorders among children and youth identifies important differences among age groups and certain social determinants of health.Given the implications of the early onset and lifetime burden of mental disorders, more resources need to be directed toward effective prevention and intervention initiatives for vulnerable children and youth in both high-income and low-and middle-income countries across the globe.
