AIM: To investigate the mortality of suicide in Shandong province and the distribution among different populations, and study the evoking factors and ways of suicide together with the family structure.
METHODS: 1 A prospective cohort study was performed in 8 areas of Shandong province from January 1988 to December 1992, with the clues of rural doctors and the data collected by psychiatric physicians. There were 468 343 residents in 1998 and 479 438 residents in 1992 among 8 observational areas. According to the rescuing records of rural health center, 74 suicide uncompleters were selected for a case-control study, while 72 subjects who matched in gender and age were taken as normal control group. A total of 84 767 subjects from 15 cities of Shandong province were examined by an epidemiologic survey, adopting random stratified sampling in cluster and the investigation by psychiatric physicians. 2 All the testees were surveyed for gender, age and occupation, etc. Family environment scale of 10 factors was used to evaluate the suicide uncompleters and normal controls.
RESULTS: 1 The mortality of suicide in population of 15 years old and above were 22.32 per 1 000 000 in the group of cohort study and 16.66 per 1 000 000 in the group of sampling survey. The suicide mortality of females was obviously higher than that of males in the cohort study group (27.36, 17.26 per 1 000 000, χ2=21.64, P < 0.01), and the sampling study group was the same (20.52, 12.72 per 1 000 000, χ2=3.86, P < 0.05). 2 The commonest evoking factors of suicide were family conflict (58.9%, 45%, 64%) and mental disorder (11.1%, 24%, 9%), and the mainly way of suicide was taking poison (62.2%, 67%, 90%). 3 The result of case-control study showed that, the factor scores of cohesion, intellectual-cultural orientation, active-recreational orientation and organization in the family of suicide were lower than those in the family of control group, while the factor score of conflict in suicide family was higher than that in control group.
CONCLUSION: By three epidemiologic study methods, it is found that the mortality of suicide is higher in the females of Shandong province, the cause is family conflict and taking poison is major way of suicide.
