Abstract

Objective: To examine spatial-temporal distribution and risk of suicide, as well as trends in suicide mortality rates, in the indigenous and non-indigenous population of the state of Mato Grosso do Sul, Brazil.

Methods: Data were obtained from the Information Department of the Brazilian Unified Health System. Deaths recorded as voluntary self-inflicted injuries (ICD-10 codes X60.0 to X84.9) were considered suicide. Suicide rates were estimated and adjusted by age in the population > 9 years of age. Kernel analysis was used to assess the spatial distribution of suicide cases, while trend analysis was carried out using a non-parametric test (Mann-Kendall).

Results: The suicide risk among the indigenous population was 8.1 (95%CI 7.2-9.0) times higher than in the non-indigenous population. For indigenous residents in the 15-24 age group, the risk was 18.5 (95%CI 17.5-19.6) times higher than in the non-indigenous population. The majority of indigenous cases were concentrated in a few villages in reservation areas, mainly occupied by Guarani-Kaiowá and Guarani-Ñandeva groups. Rate patterns remained stable over time in both groups.

Conclusion: Suicide is a serious public health problem in Mato Grosso do Sul, and has had an alarming and disproportionate impact on the indigenous population for more than a decade.

巴西中部的时空趋势和自杀风险:一项对比土著和非土著居民的生态研究。
目的:研究巴西南马托格罗索州土著和非土著居民自杀的时空分布和风险,以及自杀死亡率的趋势:研究巴西南马托格罗索州(Mato Grosso do Sul)原住民和非原住民自杀的时空分布和风险,以及自杀死亡率的趋势:数据来自巴西统一卫生系统信息部。记录为自愿自残(ICD-10代码X60.0至X84.9)的死亡被视为自杀。在年龄大于 9 岁的人群中,对自杀率进行了估算和年龄调整。核分析用于评估自杀病例的空间分布,而趋势分析则采用非参数检验(Mann-Kendall):结果:原住民的自杀风险比非原住民高 8.1 倍(95%CI 7.2-9.0 倍)。15-24 岁年龄组的原住居民的自杀风险是非原住居民的 18.5 倍(95%CI 为 17.5-19.6 倍)。大多数土著病例集中在保留区的几个村庄,主要由瓜拉尼-卡伊瓦(Guarani-Kaiowá)和瓜拉尼-南德瓦(Guarani-Ñandeva)群体居住。随着时间的推移,这两个群体的自杀率模式保持稳定:在南马托格罗索州,自杀是一个严重的公共卫生问题,十多年来对土著人口的影响令人震惊且不成比例。
