Background: On a global scale, the mental health consequences of eating habits among the general population are becoming a concern. Particular attention should be directed to the youthful population. Aims: Determine the relationship between university students’ consumption of junk food and their levels of stress, anxiety, and depression. Method: University students were asked to complete: a demographic questionnaire, questions on junk food consumption, and depression anxiety stress scores (DASS-21). Body mass index measurements were taken. Logistic regressions were utilized to construct odds ratios (ORs) with 95% confidence intervals to identify the association between university students’ consumption of junk food and their levels of stress, anxiety, and depression. Results: There were ( N = 509), 66% females and 34% males, mean age was ( M = 18.1 ± .5) years participated in this study. Daily consumption of junk food was significantly linked to stress (odds ratio [OR], 4.5; 95% confidence interval [CI], 2.5−8.3), anxiety (OR, 11.1; 95% CI, 6.2−20.1), and depression (OR, 7.9; 95% CI, 4.5−13.9). Conclusions: This is the first thorough study conducted in Egypt to examine the relationship between stress, anxiety, and depression, and junk food consumption among undergraduates at a private Egyptian university. Many college students struggle emotionally, and those who are emotionally troubled are more likely to participate in eating unhealthy food. Our research will be used to inform regional policies on adolescent nutrition and to create preventative strategies.

Mass vaccination is the most effective strategy against the spread of the COVID-19 pandemic. However, concerns about the vaccine’s safety and effectiveness remain a huge obstacle to vaccine acceptance. The aim of the present study was to explore different COVID-19 vaccine outcomes, including the development of adverse events and/or COVID-19 infection following COVID-19 vaccination. A cross-sectional study was conducted by distributing an online survey targeting staff and students at the British university in Egypt. A total of 637 participants fully completed the survey. Of these, 609 (95.6%) participants received the COVID-19 vaccine. Only 12.6% of the total vaccinated participants reported COVID-19 infection after vaccination. Of these, only 2.8% reported having severe symptoms while 9.9% reported having no or mild symptoms. The most common side effects reported after the first vs. second dose were headache (36.3% vs. 14.6%), tiredness and fatigue (26.9% vs. 10.7), and fever (25.6% vs. 6.7%). In conclusion, the present study explored different COVID-19 vaccine outcomes where the overall incidence of side effects is higher after the first dose than after the second dose. There is a relationship between COVID-19 vaccines’ side effects and gastrointestinal disorders, gender, and the type of COVID-19 vaccine. Post-vaccination symptoms were more frequently reported in women compared to men and more frequent with viral vector vaccines compared to other types. The effectiveness of different types of COVID-19 vaccines was confirmed by the lower incidence rate of post-vaccination COVID-19 infection.
