[New research horizons of epidemiology applied to mental health.]

Epidemiological research in psychiatry has always played an important role, having allowed a precise classification of psychiatric disorders and a quantification of their spread in the general population. In the current context of precision psychiatry, the fields of development of epidemiological research include: 1) the relationship between mental health and physical well-being, overcoming the stigma associated with psychiatric disorders; 2) gender differences; 3) the impact of the physical environment on mental health beyond the socio-cultural context. These issues can be explored through a close collaboration between various health professionals, and also by spreading the culture of mental health monitoring in contexts outside psychiatry.
