Both perceived job insecurity and unemployment has been associated with an increased risk of developing mental ill health. It has, moreover, been proposed that an insecure employment may be as detrimental as unemployment itself.
To estimate incidence rate ratios (RRs) of (i) redeemed prescriptions for psychotropic drugs and (ii) psychiatric hospital treatment due to mood, anxiety, or stress-related disease, among fixed-term contract workers (as an operationalization of insecure job) vs. unemployed, in the general population of Denmark.
Data on baseline employment status were drawn from the Danish Labor Force Surveys in the years 2001-2013. Participants (10,265 fixed-term contract workers and 7926 unemployed) were followed for up to 5 years in national registers (2439 cases of psychotropic drug use, 71,516 person years; 311 cases of psychiatric hospital treatment, 86,790 person years). Adjusted RRs were obtained by Poisson regression. We aspired to minimize health selection effects by (i) exclusion of survey participants who received sickness benefits, social security cash benefits, psychiatric hospital treatment or a prescription for psychotropic drugs, within 1-year prior to baseline (n = 11,693), (ii) adjustment for age, gender, level of education, calendar year, disposable family income and maternity/paternity benefits within 1-year prior to baseline.
The adjusted RR for fixed-term contract workers vs. unemployed was 0.98 (99.5% CI: 0.87-1.11) for psychotropic drugs and 0.93 (99.5% CI: 0.67-1.30) for psychiatric hospital treatment.
The present study did not find significant differences in the risk of developing mental ill health between fixed-term contract workers and unemployed, and thus suggests that fixed-term contracts may be as detrimental as unemployment.

感知到的工作不安全感和失业都与心理健康问题风险增加有关。此外，有人提出不稳定就业可能与失业本身一样有害。
在丹麦普通人群中，估计定期合同工（作为不稳定工作的一种体现）与失业者相比，（i）精神药物处方赎回量以及（ii）因情绪、焦虑或与压力相关疾病而接受精神病医院治疗的发病率比值（RRs）。
2001 - 2013年丹麦劳动力调查提供了基线就业状况数据。在国家登记册中对参与者（10265名定期合同工和7926名失业者）进行了长达5年的跟踪（2439例精神药物使用病例，71516人年；311例精神病医院治疗病例，86790人年）。通过泊松回归获得调整后的RRs。我们希望通过以下方式尽量减少健康选择效应：（i）排除在基线前1年内领取疾病津贴、社会保障现金津贴、接受精神病医院治疗或有精神药物处方的调查参与者（n = 11693），（ii）对年龄、性别、教育程度、日历年份、家庭可支配收入以及基线前1年内的产假/陪产假津贴进行调整。
定期合同工与失业者相比，精神药物的调整后RR为0.98（99.5%CI：0.87 - 1.11），精神病医院治疗的调整后RR为0.93（99.5%CI：0.67 - 1.30）。
本研究未发现定期合同工和失业者在患心理健康问题风险上存在显著差异，因此表明定期合同可能与失业一样有害。
