Effects of socioeconomic factors on secular trends in suicide in Japan, 1953-86.
The effects of socioeconomic factors on secular trends in suicide rates in Japan for the periods 1953-72 and 1973-86 were investigated using twelve socioeconomic indicators. Multiple regression analysis showed that the socioeconomic indicators affecting suicide rates were not identical in the two periods. The rates in both sexes in 1953-72 were closely related to unemployment rate and the labour force but between 1973 and 1986, divorce rate and the proportion in tertiary industry were most influential. The changes reflect the socioeconomic changes in industrial structure in Japan in transition from an industrial to a service economy.
