目的了解辽宁省城乡居民自杀死亡的状况,为预防自杀提供依据。方法采用辽宁省疾病预防控制中心1999—2003年城乡自杀死亡资料及公安部门提供的人口数据,对辽宁省城乡自杀死亡进行分析。结果辽宁省城市居民1999—2003年平均自杀死亡率为6.28/10万,农村为18.34/10万,农村高于城市(χ2=1626.74,P<0.0001)。自杀死亡率随年龄增长而增高,男性高于女性,但农村15～24岁女性高于男性(χ2=5.48,P<0.05)。城乡间自杀方式构成存在统计学意义(χ2=778.75,P<0.01)。农村自杀死亡时间季节性较城市明显。结论辽宁省城乡居民自杀死亡率差异显著,应重点对农村、老年、男性及15～24岁农村女性采取有针对性的预防措施,以降低自杀死亡率。
Objective To understand the suicide death status of urban and rural residents in Liaoning Province and provide evidence for suicide prevention. Methods The data of suicide deaths in urban and rural areas from 1999 to 2003 in Liaoning Province Centers for Disease Control and Prevention and population data provided by the public security department were used to analyze the suicide deaths in urban and rural areas of Liaoning Province. As a result, the average suicide mortality rate of urban residents in Liaoning Province during 1999-2003 was 6.28 per 100 000, rural areas was 18.34 per 100 000, and rural areas were higher than urban areas (χ2=1626.74, P<0.0001). Suicide mortality increased with age, males were higher than females, but rural females aged 15-24 years were higher than males (χ2=5.48, P<0.05). There was a statistically significant difference in suicide between urban and rural areas (χ2=778.75, P<0.01). Rural suicide deaths are more seasonal than urban ones. Conclusion The suicide mortality rate between urban and rural residents in Liaoning Province is significantly different. Targeted prevention measures should be taken for rural, aged, male and rural women aged 15 to 24 to reduce suicide mortality.
