Prevalence of depression, anxiety and stress after the COVID-19 pandemic period among students at the Medical University of Sofia; Significance of demographic, educational, and pandemic-related variables

This cross-sectional study aimed to determine the prevalence of depression, anxiety, and stress among undergraduate dental students at Sofia Medical University and to investigate its associations with some demographic, educational and pandemic-related variables. A self-reported questionnaire that included the validated DASS-21 scale was administered to a group of 2nd, 3rd, 4th, and 5th year students (n=70, response rate 95.7%). Results indicated abnormal levels of depression, anxiety, and stress in 34.3%, 65.7% and 59.7% of the participants, respectively. A much larger proportion of females suffered from abnormal levels of anxiety (56.6%) as compared with males (9%), p=.003. Single students exhibited significantly higher level of depression (25.4%) than those having a partner (9%), p=.037. Third-year dental students demonstrated higher level of depression (19.4%) compared to 5th year students (1.5%), p=.007 as well as higher stress scores (25.4%) than 2nd year students (17.9%), p=.035. Academic performance (assessed by GPA in this study), dentistry as the first students’ choice when applying for MUS, financial responsibilities, and pandemic-related academic responses were not found significant factors for depression, anxiety, and stress (p>.05). These outcomes highlight the need to provide psychological support programs with special attention on susceptible groups. Dental students should implement preventive measures and adopt coping strategies to manage stress and reduce levels of anxiety and depression.
