The relative importance of socio-economic factors on risk for suicide in the immigrant population may differ from that for the native population; however, few studies have addressed this issue on a national basis. With a nested case-control design and data from Norwegian population registers we identified 11,409 suicide cases in the years 1992-2012 and 191,785 sex-birthdate-matched controls. The influence of socio-economic factors on the risk for completed suicide was assessed through conditional logistic regression. Among 11,409 suicides, 1139 (10%) were individuals with an immigration background of either themselves or their parent(s). Suicide cases, as well as the controls, with an immigration background differed in several aspects of their socio-economic status from those without such a background. Being single or separated, divorced or widowed, was, however, associated with an increased risk of suicide regardless to the subjects' immigration background. Low level of education and low annual income significantly increased the risk for suicide in almost all the study subgroups. Living in the capital area was associated with a reduced risk of suicide in first-generation immigrants but an increased risk in native Norwegians. In conclusion, persons with an immigration background, as well as native Norwegians, shared most common risk factors for suicide, but the strength of associations between socio-economic factors and risk for suicide can differ by immigration background.
社会经济因素对移民人群自杀风险的相对重要性可能与本土人群不同；然而，很少有研究从全国范围探讨这个问题。本研究采用巢式病例对照设计，利用挪威人口登记处的数据，于 1992 年至 2012 年期间确定了 11409 例自杀病例和 191785 名性别、出生日期相匹配的对照。通过条件逻辑回归评估社会经济因素对完成自杀风险的影响。在 11409 例自杀者中，有 1139 人（10%）有移民背景，或其父母有移民背景。有移民背景的自杀病例和对照在社会经济地位的几个方面与没有移民背景的人不同。然而，无论其移民背景如何，单身或分居、离婚或丧偶与自杀风险增加相关。受教育程度低和年收入低显著增加了几乎所有研究亚组的自杀风险。居住在首都地区与第一代移民自杀风险降低相关，但与挪威本地人自杀风险增加相关。总之，有移民背景的人与挪威本地人有许多共同的自杀风险因素，但社会经济因素与自杀风险之间的关联强度可能因移民背景而异。
