Suicide in Hong Kong 1971-1990: age trend, sex ratio, and method of suicide.

This study gives an overview of the suicide rates in Hong Kong in the last 2 decades (1971-1990). It was found that the average suicide rate for the whole population was 11.3 per 100,000 population and it has been quite steady in recent years. The male and female adolescent (age-group 10-24 years) suicide rates were approximately the same, while the ratio of the overall male to female rate was 1.3:1. This indicated a relatively high female rate as compared with other countries. An examination of the suicide rates for various age-groups showed that the rate increased with age. The adolescent suicide rate was not particularly high (4.7 per 100,000 population for the age-group 10-24 years), but that for the elderly was 4-5 times the overall rate (49.5 per 100,000 population for those aged over 70 years). As regards the method of suicide, jumping from a height and hanging predominated in all age-groups. These methods were in great contrast to those used in other countries.
