The authors analyzed occupaitional and non-occupational psycho-social factors for comprehensive school teachers, evaluated their health state according to self-estimation and to thorough medical examinations conducted in prophylactic examinations. Findings are that the major working hazard for the teachers is work intensity: about 80% of the teachers consider the work physically exhausting and nearly 90% assume the work exhausting morally. High prevalence of general non-infectious diseases and health state complaints necessitates regular periodic medical examinations for teachers.
