The objective of the study was to estimate the odds ratio for the association between unemployment and parasuicide, controlling for potential confounding variables.
A case-control study was conducted involving 507 cases of parasuicide and 200 age- and sex-matched controls presenting to emergency departments in Edmonton, Canada. Subjects were interviewed using an extensive questionnaire developed for a World Health Organization study of parasuicide. The data were analyzed using conditional logistic regression.
In a crude analysis, the odds ratio for the association between unemployment and parasuicide was 12.0 (95% confidence interval, 6.0-23.9). After controlling for sociodemographic factors, lifetime prevalence of several Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition, disorders, previous parasuicide, hopelessness, childhood experiences, and emotional support from family and friends, the odds ratio was 5.2 (95% confidence interval, 2.3-11.4).
Those who are unemployed have an increased risk of parasuicide, and this association persists after accounting for a wide range of potential confounders.
本研究的目的是估计失业与准自杀之间关联的比值比，并控制潜在的混杂变量。
开展了一项病例对照研究，纳入了507例准自杀病例以及200例年龄和性别匹配的对照，这些对照来自加拿大埃德蒙顿的急诊科。使用为世界卫生组织一项准自杀研究开发的一份详尽问卷对受试者进行访谈。采用条件逻辑回归分析数据。
在粗分析中，失业与准自杀之间关联的比值比为12.0（95%置信区间为6.0 - 23.9）。在控制了社会人口学因素、《精神障碍诊断与统计手册（第三版修订本）》中几种障碍的终生患病率、既往准自杀史、绝望感、童年经历以及来自家人和朋友的情感支持后，比值比为5.2（95%置信区间为2.3 - 11.4）。
失业者有更高的准自杀风险，并且在考虑了广泛的潜在混杂因素后，这种关联依然存在。
