The process of migration and resettlement has been associated with increased risk for psychiatric illness. Our study sought to examine the association between age at immigration and risk for mood, anxiety, and substance use disorders (SUDs) among adult immigrants in Canada.
Data from the Canadian Community Health Survey: Mental Health and Well-Being, a cross-sectional study of psychiatric disorder conducted in 2002, was used to identify a representative sample of adult immigrants in Canada (n = 4946). Logistic regression was used to examine the association between age at immigration (0 to 5 years, 6 to 17 years, and 18 years and older) and 12-month prevalence of mood and anxiety disorders, and SUDs.
Immigrants who arrived prior to age 6 years reported the highest risk for mood (OR 3.41; 95% CI 1.7 to 7.0) and anxiety disorders (OR 6.89; 95% CI 3.5 to 13.5), compared with those who immigrated at the age of 18 years or older, after adjusting for covariates, including duration of residence.
Younger age at immigration was associated with increased risk of having a current mood disorder, anxiety disorder, or SUD. These findings speak to the importance of developing and evaluating targeted prevention programs for young immigrant children and adolescents.
移民和重新安置的过程与精神疾病风险增加有关。我们的研究旨在探讨加拿大成年移民的移民年龄与情绪、焦虑和物质使用障碍（SUD）风险之间的关系。
使用 2002 年进行的一项关于精神障碍的横断面研究——加拿大社区健康调查：心理健康和幸福感的数据，确定了加拿大成年移民的代表性样本（n=4946）。使用逻辑回归来检验移民年龄（0 至 5 岁、6 至 17 岁和 18 岁及以上）与 12 个月情绪和焦虑障碍以及 SUD 患病率之间的关联。
与 18 岁及以上移民相比，6 岁之前到达的移民报告情绪（OR 3.41；95%CI 1.7 至 7.0）和焦虑障碍（OR 6.89；95%CI 3.5 至 13.5）的风险最高，调整了包括居住时间在内的协变量后。
移民年龄越小，患当前情绪障碍、焦虑障碍或 SUD 的风险越高。这些发现强调了为年轻移民儿童和青少年制定和评估有针对性的预防计划的重要性。
