Prevalence of post-traumatic stress disorder (PTSD) in university students during the COVID-19 pandemic: a meta-analysis attending SDG 3 and 4 of the 2030 agenda

Background: Most universities around the world have been heavily affected by the COVID-19 pandemic, as declared by the World Health Organization (WHO) in March 2020. Many students were isolated at home and underwent a forced transition from face-to-face learning to e-learning, at least in the first few months. The subsequent months and years were typically characterised by a slow return to normal learning under COVID-19 protocols and restrictions. A potential consequence of the lockdowns, social restrictions and changes to learning is the development of PTSD (post-traumatic stress disorder) in university students, affecting their health and well-being (SDG3) and quality of education (SDG4). Materials and Methods: Medline was searched through PubMed for studies on the prevalence of PTSD in university students from 1 December 2019 to 31 December 2021. The pooled prevalence of PTSD was calculated with random-effects models. Results: A total of six studies were included, across which the prevalence of PTSD among university students was 23%. Meta-regression showed that the prevalence of PTSD was significantly higher with older age, but independent of the percentage of women in a study or its methodological quality. Conclusions: Our results suggest that students suffer from PTSD at a moderate rate. Measures are needed to address the mental health issues of university students that have arisen during COVID-19 all around the world. © 2022 by the authors. Licensee MDPI, Basel, Switzerland

Understanding the emergence of infectious diseases: Social representations and mass media

The present study examines social representations of the threat created by emerging infectious diseases. A free association experiment was carried out in which the stimulus was a news item where the framing of a discourse (human interest vs. attribution of responsibility) was manipulated. Results showed that the human interest discourse sparked off representations linked to vulnerability, while the responsibility discourse produced representations concerning preventive health care promoted by the authorities. Even so, the effect of the discourse was limited and showed that the new information is anchored in previous interpretive schemes. Implications of mass media on health communication are considered
