The Lundby study is a longitudinal, epidemiological study of mental disorder in the normal Swedish population. The study began in 1947. Ninety-nine percent of the 2550 inhabitants of Lundby were personally examined by psychiatrists. Of the 3563 persons evaluated, 735 died. During the observation period, 28 subjects committed suicide (23 males, 5 females). Due to the few female suicides, only males have been studied concerning rates of suicide.
