This cross-sectional survey revealed a high prevalence of mental health symptoms among health care workers who involved patient care during COVID-19 in central Ethiopia. Overall, 60.3%, 78%, and 33.8% of the study participants were self-reported symptoms of depression, anxiety, and stress respectively. This study was found higher than the study conducted among healthcare workers in China that showed 50.7% of symptoms of depression, 44.7% of anxiety, and 73.4% of stress(7). Again, our study was higher than the result in Iraq that revealed 45% of depression, 47% of anxiety, and 18% of stress (13). This difference may be due to high fear of COVID-19 with a lack of personal protective equipment that indicated 71.1% of respondents report limited personal protective material in our study. In resourced countries like China this is not much concern as low resourced counties.
Most age categories have a risk of developing stress symptoms and the age category of 26 to 30 had significantly associated with depression when compared to the age category of 18 to 25. This result was in line with the study done in China(14). As age advanced, there is a higher burden of the family, which influences the symptoms of mental health status, as they are more likely to worry about their families(15). Married healthcare workers had also a higher odds ratio of depression and stress. This can be explained by when pandemic disease happened with severe morbidity and mortality that high-risk transmission to their family, health care workers might have more stress, and depression.
In this study, depression, anxiety, and stress were higher in women, showing that the mental health status during the COVID-19 pandemic highly significant in women. This is in line with the study report done in Turkey (16) and that confirmed female gender has been identified as potentially exposed to symptoms of mental health problems after the happening of pandemics(17). A study from China found that women have three-folds higher anxiety, depression, and stress than in men during the COVID-19 pandemic(18).
In this study, we found that healthcare workers who have working in Addis Ababa and Oromiya especial zone were significantly associated with symptoms of depression, anxiety, and stress. This may be because Addis Ababa and Oromiya especial zone have a higher incidence of the COVID-19 infected patients and increasing every day than other central Oromiya regions. Regarding professional attributes, compared with pharmacists, medical laboratory professionals had a higher risk of depression, anxiety, and stress, whereas nurses had a higher risk of depression symptoms. This may be due to medical laboratory technologists/technicians and nurses have higher exposure to blood-contacting, workload, and stay in the ward a long time and provide direct nursing practice to patients respectively. This was reported in the studies in done China(19, 20). This situation may be influenced in their mental health status symptoms of depression, anxiety, and stress.
The study result shows that healthcare workers who had working in the COVID-19 treatment center had a higher risk of symptoms of depression, anxiety, and stress. This result was similar to the study conducted in China(8). Again, healthcare workers who have working in the emergency department, surgical department, outpatient department, and the laboratory department had significantly associated with self-reporting symptoms of depression. This was observed in the studies reported in Fujian, China (20), China (14), and Landon, United Kingdom (6). This can also be explained by the high-risk exposure area of the working department.
In this study, healthcare workers who have working experience of less than 10 years had a higher risk of depression and anxiety symptoms. This explained by those health care workers who have low experience in their working environment during a disease outbreak might have a higher fear of contagion, depression, and anxiety. Additionally, the study participants who have no training had higher anxiety. During the occurrence of outbreak disease, training regarding the prevention and control mechanisms, personal protection methods, the severity of the disease, transmission method and in addition to psychological intervention should be provided in time for health care workers (20, 21). In This study, we found 71.1% of health care workers reported a shortage of personal protective equipment which has significantly associated with symptoms of depression. Ensuring staff protection from the COVID-19 pandemic is very essential to have a better capacity for disease prevention and mental health outcome that targeted to minimize the fear of the pandemic (21). A systematic review and meta-analysis study found that having personal protective medical equipment, following preventive actions and timely informed about the COVID-19 are among protective factors (19).
Limitation of the study
This study has several limitations; first, as a cross-sectional nature of the study, it does not show a causal relationship. Second, the study restricted only in the central Ethiopia, which cannot generalizable for the other region of Ethiopia. Third, to minimize the spread of the COVID-19 infection, all study participants in the working department were taken, which may have a selection bias.
