Impact of COVID-19 on the Life of Higher-Education Students in İstanbul: Relationship Between Social Support, Health-Risk Behaviors, and Mental/Academic Well-Being.

Objective: This study aimed to draw a general picture of the impact of the coronavirus disease 2019 (COVID-19) -pandemic on the life of higher-education students in İstanbul, with specific emphasis on the relationship between students' social support systems, health-risk behaviors, and mental/academic well-being.

Methods: A total of 2583 higher-education students from different fields of study participated in an online survey gathering information from several domains, including available social networks, support-seeking attitudes, substance use patterns, physical activity levels, academic stress, academic satisfaction, and psychological well-being during the pandemic.

Results: Our findings pointed to major changes in students' life circumstances and daily routines during COVID-19, including a significant decrease in contact with friends, overall substance use, and physical activity as well as high levels of depression, academic stress, and academic dissatisfaction. Depressive symptoms were significantly predicted by the loneliness score (OR = 2.08, 95% CI = 1.88-2.29), female gender (OR = 1.65, 95% CI = 1.21-2.24), frequency of binge drinking (OR = 1.4, 95% CI = 1.06-1.86), and level of academic stress (OR = 1.15, 95% CI = 1.1-1.19), whereas the number of people to easily borrow money from was found to be a protective factor against depression (OR = 0.95, 95% CI = 0.92-0.99).

Conclusion: Our results highlight the need for higher-education institutions to take the appropriate social and mental health interventions, tailored to fit the specific requirements of the COVID-19-related measures.
