The ongoing global economic crisis may have affected people's mental health. This study aimed to, among a sample of the working population, estimate and compare the prevalence of depressive and anxiety disorders in different time intervals from January 2008 to October 2009 and to examine the demographic and socioeconomic correlates of mental disorders.
From January 2008 to October 2009, 3579 employees in Alberta were recruited using the random digit dialing method. Mental disorders were assessed using the World Health Organization's Composite International Diagnostic Interview-Auto 2.1. The lifetime and 12-month prevalence of depressive and anxiety disorders in different time intervals were estimated and compared.
The 12-month prevalence of major depressive disorder (MDD) before September 1, 2008; between September 1, 2008, and March 1, 2009; and between March 1, 2009, and October 30, 2009, was 5.1%, 6.8%, and 7.6% (P = 0.03), respectively. The lifetime prevalence of dysthymia reported during the 3 periods was 0.4%, 0.7%, and 1.5% (P = 0.006), respectively. No changes in the 12-month prevalence of social phobia, panic disorder, and generalized anxiety disorder were found over time.
The ongoing global economic crisis may have contributed to the increased prevalence of MDD. Future studies are needed to monitor the changes in the prevalence and to describe how the event may affect people's employment status, income, and health.
当前的全球经济危机可能对人们的心理健康产生影响。本研究旨在对劳动力样本进行评估，比较 2008 年 1 月至 2009 年 10 月不同时间段内抑郁和焦虑障碍的患病率，并探讨精神障碍的人口统计学和社会经济学相关性。
2008 年 1 月至 2009 年 10 月，采用随机数字拨号法在艾伯塔省招募了 3579 名员工。使用世界卫生组织复合国际诊断访谈自动 2.1 版评估精神障碍。估计并比较了不同时间段内终身和 12 个月的抑郁和焦虑障碍的患病率。
2008 年 9 月 1 日前、2008 年 9 月 1 日至 2009 年 3 月 1 日和 2009 年 3 月 1 日至 2009 年 10 月 30 日期间，重度抑郁症（MDD）的 12 个月患病率分别为 5.1%、6.8%和 7.6%（P=0.03）。3 个时期报告的心境恶劣的终身患病率分别为 0.4%、0.7%和 1.5%（P=0.006）。社交恐惧症、惊恐障碍和广泛性焦虑障碍的 12 个月患病率随时间变化无变化。
当前的全球经济危机可能导致 MDD 的患病率增加。需要进一步研究来监测患病率的变化，并描述该事件如何影响人们的就业状况、收入和健康。
