目的了解宁夏生态移民自杀意念的现况,分析影响移民人群自杀意念的危险因素,为预防自杀提供参考。方法在宁夏地区生态移民安置区,采用多阶段抽样方法,抽取≥18岁常住农村居民2 000人,采用中文版复合型国际诊断交谈表-计算机辅助入户进行访谈,以近1年来是否认真考虑过自杀为自杀意念阳性判断标准。自杀意念危险因素分析采用Logistic回归模型。结果近1年生态移民自杀意念报告率为5.31%(95%CI:4.21%~6.41%),年龄标化后生态移民自杀意念发生率为5.73%(95%CI:4.59%~6.87%),不同性别移民自杀意念标化报告率[男性为3.02%(95%CI:1.66%~4.38%)、女性为7.44%(95%CI:5.80%~9.07%)]差异有统计学意义(2=13.12,P<0.001),近1年回、汉族移民自杀意念报告率分别为6.07%和4.46%,差异无统计学意义(2=2.06,P=0.150)。Logistic回归分析进入方程的因素有:女性(OR=2.25,95%CI:1.30~3.89)、年龄(OR=1.03,95%CI:1.01~1.04)、精神障碍史阳性(OR=4.54,95%CI:2.89~7.15)、县外移民(OR=1.59,95%CI:1.00~2.54)。结论影响生态移民自杀意念的因素是多方面的,精神障碍史阳性、女性、高年龄以及县外移民自杀意念发生风险增加。
Objective To understand the status quo of suicidal ideation of ecological immigrants in Ningxia and to analyze the risk factors of suicidal ideation affecting immigrants, so as to provide references for preventing suicide. Methods In the resettlement area of Ningxia Hui Autonomous Region, a multi-stage sampling method was adopted to collect 2 000 resident rural residents aged 18 or above. The interview was conducted with the help of a computer-assisted intercom with the Chinese version of the compound international diagnostic interview form. In the past year, Suicide as a positive criterion for suicidal ideation. The risk factors for suicidal ideation were analyzed using Logistic regression model. Results The reported rate of suicidal ideation of ecological immigrants was 5.31% (95% CI: 4.21% ~ 6.41%) in the past year. The incidence of suicidal ideation of ecological immigrants was 5.73% (95% CI: 4.59% ~ 6.87% The reported rates of suicide ideation among different gender immigrants were statistically significant (3.02% (95% CI: 1.66% -4.38%) in males and 7.44% (95% CI: 5.80% ~ 9.07%) in females = 13.12, P <0.001). The report rates of suicide ideation of Han immigrants in the past year were 6.07% and 4.46% respectively, with no significant difference (2 = 2.06, P = 0.150). Logistic regression analysis included the following factors: female (OR = 2.25, 95% CI: 1.30-3.89), age (OR = 1.03, 95% CI: 1.01-1.04), history of mental disorders (OR = 4.54, 95% CI: 2.89 ~ 7.15), immigrants outside the county (OR = 1.59, 95% CI: 1.00 ~ 2.54). Conclusion The factors affecting suicidal ideation of ecological immigrants are multifaceted. The incidence of mental disorders is positive, and the suicidal ideation of women, high age and immigrants beyond the county is at increased risk.
