Young men in the North

Young men in the North - The conscription cohort in the Northern Finland

Military service is obligatory for men in Finland. However, in the Northern Finland around one third of men attending military call-up session are rejected from service due to problems in somatic or mental health. In addition, around 13% of those entering the service are pre-term exempted because of health problems. Failure in military service may expose young man in risk for marginalisation. This cohort study focuses on somatic and mental health deficits as well as social factors relating to coping in military service and its longitudinal consequences in adult life. It also investigates protective factors that may enhance wellbeing and reduce the risk for marginalisation.
