Prevalence of psychiatric disorders during pregnancy-a feasibility study at second trimester ultrasound in the general population (GROUP study): study protocol.

Introduction: During the perinatal period, women have an increased risk for psychiatric disorders, which are highly prevalent in this context. In addition, there are significant delays in diagnosing these conditions, worsening their prognosis and increasing their societal burden. Studies describing psychiatric disorders in the perinatal period often focus on specific disorders; only postpartum depression and, to a lesser extent, anxiety disorders are studied.
