Determinants of COVID-19-related knowledge and preventive behaviours among students in reopened secondary schools: cross-sectional study

PURPOSE: In Ethiopia, more than 26 million students have been out of the classroom for nearly 9 months. On 18 September, the Ethiopian Minister of Health advised the Parliament the possibility of reopening schools provided certain conditions were met. Schools are currently reopening in the country for the first time since March 2020. OBJECTIVE: This study assessed the knowledge and preventive health behaviours toward COVID-19 and associated factors among secondary school students. DESIGN, SETTING, PARTICIPANTS AND OUTCOME MEASURES: An institution-based cross-sectional study was conducted from October to December 2020 in Gondar city, Northwest Ethiopia. A total of 370 secondary school students were included. Bivariable and multivariable ordinal logistic regression model were fitted to identify the predictors of knowledge about COVID-19. Simple and multiple linear regression analysis were done to identify factors associated with preventive behaviour. A p<0.05 was used to declare statistical significance. RESULTS: Only one-fourth (23.5%, 95% CI 19.5% to 28.1%) of the participants had a good knowledge about COVID-19. The mean score of preventive behaviour was 22.8±SD 6.2. Marital status, religion, father education, living arrangement and sources of information were significantly associated with knowledge about COVID-19. Being female and using health professionals as source of information increased the engagement in preventive behaviours. On the other hand, student whose father employed in non-governmental organisation and other jobs had decreased engagement in preventive health behaviours. CONCLUSION: Significant number of the students had inadequate knowledge about COVID-19 and poorly engaged in COVID-19 preventive behaviour. Thus, it is suggested to include and disseminate about COVID-19 in related academic sessions, using school clubs and minimedias. The sources of COVID-19-related information need to strengthen the dissemination of tailored, credible and timely message to enhance the knowledge and engagement of the students in preventive behaviours.
