Perceived risks of COVID-19, attitudes towards preventive guidelines and impact of the lockdown on students in Uganda: A cross-sectional study.

BACKGROUND: This study explored students' perceptions of COVID-19 risks and preventive measures and assessed the impacts of the national lockdown on students in Uganda. METHODS: A web-based survey was conducted to explore students' perceived risks of COVID-19 and preventive measures; sources of COVID-19 information and impacts of the lockdown. Both undergraduate and post-graduate students (n = 398) participated in the study. Data were analysed using IBM-SPSS-26. RESULTS: Students acknowledged COVID-19 as a health risk, and their preventive behaviours were influenced by age, gender, marital status and living situation. Most students followed face mask guidelines but did not comply with lockdown restrictions. Social distancing was not always possible due to overcrowding. Students' main sources of COVID-19 information were local media (e.g., TV, radio) and social media. Most students (especially females) were unable to access online learning platforms due to poor internet connectivity, high costs and no access to computers. Meanwhile, a majority of those who studied online did not enjoy the experience. Students experienced depression, frustration, stress and anxiety during the lockdown; became less physically active and spent most of their time on social media, sleeping, eating or watching movies. Some students indulged in smoking, drinking alcohol, taking drugs and gambling for their first time, while others did them more often than before. CONCLUSION: The increase in sedentary activity, poor mental health and substance use over the lockdown period puts students at risk of health complications and poses a potential threat to the healthcare system. These risks may also negatively impact their future learning and academic potential. Further research is needed to understand the transitional experiences of students between physical and virtual learning, and how they can be supported. There is also a need to ascertain the feasibility of guidelines such as social distancing in developing countries, to increase compliance.

Air pollution exposure in relation to guard duty at Tidworth Camp: A cross-sectional study.

BACKGROUND: Air pollution is the largest environmental health risk in the United Kingdom, and an issue of concern amongst outdoor workers. Road transport is a major source producing the largest amount of nitrogen dioxide (NO2) and ozone (O3) (as a secondary pollutant). Hundreds of vehicles enter and exit the Tidworth Camp's main gate daily, potentially producing these pollutants. However, the air pollution exposure experienced by personnel on guard duty is unknown. This study aimed to determine and compare background NO2 and O3 levels experienced by personnel on guard duty. METHODS: Cross-sectional data was collected using a static sampling technic on randomly selected days of the week. Data analysis was done using IBM-SPSS-26 and a p-value of <0.05 was considered statistically significant. RESULTS: The background concentration of NO2 and O3 pollutants were within recommended limits. There was no significant difference between mean morning and afternoon exposure levels for both pollutants. However, NO2 and O3 levels were significantly higher during weekdays compared to weekends (M = -0.022, SD = 0.007, t(6) = -8.672, p <0.0001 and M = -0.016, SD = 0.008, t(6) = -5.040, p = 0.002 respectively). Both pollutants showed no significant differences in exposure levels when only weekdays were compared. NO2 levels showed a weak positive correlation during weekdays (r = 0.04) and a strong positive correlation during weekends (r = 0.96). O3 levels had a positive correlation on both weekdays and weekends; however, levels on Monday showed a negative correlation (r = -0.55). Linear regression analysis showed that outside temperature was a significant predictor of O3 levels (p = 0.026). CONCLUSION: Personnel on guard duty experienced higher pollution levels during weekdays compared to weekends; however, air pollution levels for both pollutants were within recommended limits. Further studies are recommended over hotter months using a personal sampling technic to measure personal air pollution exposure levels in order to minimise any health and safety risks.
