Objective   To understand the anxiety and insomnia of nurses in 2020 and its influencing factors, so as to provide orientation for formulating relevant policies.

  Methods   A total of 738 nurses in a designated hospital for treatment of COVID-19 patients in Quanzhou were investigated by convenient sampling. The basic demographic information, cognition of COVID-19, anxiety and insomnia of these subjects were surveyed with self-made questionnaire, self rating anxiety scale (SAS) and insomnia severity index(ISI). The influencing factors of anxiety and insomnia were analyzed by multiple linear regression.

  Results   The incidence of anxiety and insomnia were 8.5% and 35.8%, respectively. The results of multiple linear regression analysis showed that regular physical exercise was the influencing factor to reduce nurses' anxiety(β =-4.226, P = 0.002) and insomnia (β = - 1.706, P = 0.003). Nurses who had a personal history of disease (β = 3.320, P = 0.023), considered resignation due to the COVID -19 (β = 5.012, P = 0.031), thought that they might infect their family members and/or friends with COVID-19 virus (β = 4.631, P < 0.001) and were treated differently by others (β = 3.829, P = 0.003) had more anxiety; nursing staff who had a personal history of disease (β = 1.277, P = 0.036), considered resignation due to the COVID-19 (β =1.946, P = 0.045), worried about infecting other people with novel coronavirus (β = 1.063, P = 0.006), thought that they might infect their family and friends with COVID-19 virus (β =1.156, P = 0.003) and were treated differently by others (β =1.507, P = 0.004) also had more serious insomnia. There was a positive correlation between anxiety and insomniaβ and its 95% CI value was 0.280(0.258, 0.302, P < 0.001).

  Conclusions   In 2020 nurses in Quanzhou had anxiety and insomnia, which were affected by many factors. Employers should pay attention to the mental health of high-risk personnel and carry out psychological intervention when necessary.
