Abstract:Objective To describe the level and epidemic features of death due to suicide among the elderly in Yunnan Province, and to provide a basis for reducing suicide among the elderly and promoting healthy aging. Methods We analyzed the epidemiological characteristics of suicide deaths among the elderly in Yunnan Province based on the provincial surveillance data from the Population Death Information Registration and Management System from 2015 to 2019. Results From 2015 to 2019, the reported suicide mortality rate of the elderly in Yunnan Province ranged from 25.02/100,000 to 28.59/100,000, and the standardized suicide mortality rate fluctuated between 25.29/100,000 and 27.17/100/000. Over the five years, the reported suicide mortality rate was higher in the male elderly than in the female elderly as well as higher in the rural elderly than in the urban elderly. The reported suicide mortality rate increased with age during the same year, and the suicide mortality rate of the male elderly aged 80 years and above was the highest (44.67/100,000-57.81/100,000). The reported suicide mortality rate of the elderly aged 80 and above showed an upward trend, with a statistically significant difference (APC=7.92%, P<0.05). Most the elderly who died of suicide were married (67.21%). Pesticide poisoning (55.86%) and hanging (34.12%) were the most common methods of suicide. Conclusion Suicide is one of the leading causes of injury death among the elderly in Yunnan Province. Comprehensive preventive strategies should be taken to reduce the incidence of suicide behavior among the elderly.
