THE STUDY OF INSOMNIA IN DIFFERENT GROUPS OF WORKERS DURING THE COVID-19 PANDEMIC

To understand the contribution of the work-related and extra-professional factors on the risk of insomnia during the COVID-19 pandemic. The survey was prepared on a GoogleDrive form. The questionnaire was distributed online and collected data from 769 responders. The dependent variable was the presence or absence of insomnia. Non parametric tests and correlations were used to find the main predictors linked with a greater chance of developing insomnia. The onset or the aggravation of the insomnia was reported by 41.01% of responders. The maximum rate was in healthcare workers (42.01%). Significant direct correlations were found between insomnia and work load, fear for the inefficiency of the personal protective equipment, changes in workplace, procedures and working schedule, belonging to a vulnerable health group, general psycho-social strain and lack of social recognition. A significant occupational stressor related to insomnia was represented by the contact with COVID-19 patients followed by fear of developing infection at work. The personal perception of risk was found a composite indicator and it was the only non-occupational factor related to insomnia. The best identified predictors for insomnia consisted in work overload (OR=2.13, CI=1.7-2.5, p=0.03), occupations supposing contact with COVID-19 patients (OR=2.04, CI =1.7-2.3, p=0.01), belonging to a vulnerable health group (OR=1.53, CI=1.1-2.3, p=0.001), personal perception of risk (OR=1.26, CI =1.2-1.3, p=0.001) and lack of social recognition (OR=1.21, CI =1-1.3, p=0.02). The study highlights the main risk factors that should be avoided in order or to reduce the occurrence of insomnia and its consequences.
