Association between occupational stress and mental health of nurses during the COVID-19 pandemic: A cross-sectional research.

Aim: This study is aimed to explore the association between the occupational stress and mental health among Chinese nurses during the COVID-19 pandemic.

Design: Cross-sectional study.

Methods: There were 2913 nurse participants enrolled in the study. Demographic characteristics and other data were measured by a self-reported questionnaire. Occupational stress was measured by using the effort-reward imbalance (ERI) questionnaire. Mental health was measured by the Patient Health Questionnaire-9 and the General Anxiety Disorder-7.

Results: Among the participants, 14.32% (417) experienced ERI; 8.1% (237) and 7.2% (210) reported depressive and anxiety symptoms, respectively. Compared with a reference group at the lowest quartile of the ERI, participants in the highest quartile had an adjusted odds ratio (OR) (95% CI) of 11.17 (4.42, 28.25) for incident depressive symptoms. For anxiety symptoms, the OR and 95% CI was 2.28 (1.21, 4.29). The ERI was shown to have a detrimental effect on mental health, especially depressive symptoms.
