Prevalence of anxiety disorders as a cause of workers’ absence

ABSTRACT Objective: to analyze the prevalence of various anxiety disorders among mental and behavioral disorders as a cause for the leave of absence of workers in the state of Piauí. Method: transversal census-based study performed with data from the National Social Security Institute. Four-hundred twelve leaves of absence of workers due to anxiety disorders in the 2015-2016 biennium were included. Results: higher prevalence was found for mixed anxiety-depressed disorder (31.2%), followed by other anxious disorders (20.6%) and generalized anxiety (14.1%). Ages from 22 to 45 years old prevailed in the group of individuals with duration of absence greater than or equal to 41 days, with statistically significant difference (p < 0.001). There was no statistically significant association (p = 0.004) between rural activity and increased time of absence. Conclusion: the study draws attention to the prevalence of “other anxiety disorders” as the cause of leave of absence, with emphasis on mixed anxiety-depressed disorder.

摘要
目的：分析皮奥伊州（Piauí）工人因精神与行为障碍类疾病请假离岗的各类焦虑障碍患病率。
方法：本研究为基于普查的横断面研究，数据来源于全国社会保障研究所（National Social Security Institute），共纳入2015-2016两年间因焦虑障碍请假的412例工人病假案例。
结果：混合性焦虑抑郁障碍（mixed anxiety-depressed disorder）患病率最高，达31.2%，其次为其他焦虑障碍（other anxious disorders，20.6%）与广泛性焦虑（generalized anxiety，14.1%）。在请假时长≥41天的组别中，22~45岁人群占比最高，组间差异具有统计学意义（p<0.001）。农村作业与更长请假时长之间未发现具有统计学意义的关联（p=0.004）。
结论：本研究提请学界关注作为请假离岗病因的各类焦虑障碍患病率，其中尤以混合性焦虑抑郁障碍为重。
