Abstract
The relationships among age, sex, marital status and suicidal behaviour in Australia and Hong Kong showed disparity in age-specific suicide rates among the four marital status groups, never married, married, widowed and divorced, for both sexes in the two locations. Examining the coefficients of preservation suggested the coefficient for never married to married in all cases was larger than 1, except for the groups of teenagers aged 15–19 years for both sexes and of elderly women aged 60 years or over in Hong Kong. The widowed or divorced groups have lower suicide rates than the married women among the elderly in Hong Kong. Hong Kong women seem not to have been benefited in marriage as much as men. Responsibility and workload in married life rather than low social status are the likely reasons for the relative high female suicide rate in Hong Kong. Possible cultural and environmental factors which are somewhat speculative (yet to be confirmed) are discussed.
