Objective@#We aimed to investigate the
association of increased
smartphone screen time with
insomnia , bedtime
procrastination ,
depression ,
anxiety ,
body mass index (BMI), and
physical activity during the
coronavirus disease of 2019 (COVID-19)
pandemic . @*
Methods @#An online
survey was performed for
university students from all regions of
Lebanon during the lockdown. The
survey included
questionnaires about
smartphone screen time ,
diet ,
physical activity , psychological symptoms, and bedtime
procrastination . We defined 6 hours of
smartphone use as critical based on a
survey done in
United States . @*Results@#Among
female students ,
smartphone use duration,
physical activity levels, BMI,
depression ,
anxiety , and
insomnia severity were significantly higher than in
male . When we stratified participants based on 6 hours of
smartphone use,
females , unhealthy
food consumption ,
insomnia ,
anxiety ,
depression , and bedtime
procrastination were significantly higher in the group with ≥6 hours of
smartphone use. When we divided based on 7 hours,
physical activity and
body weight also differed between the two groups.
Logistic regression analysis revealed that
female ,
overweight ,
insomnia , and bedtime
procrastination were significant predictors of a phone
screen time of 7 hours. @*Conclusion@#Our findings suggest that
adults should be more cautious and responsible when using
smartphones and be more concerned about the
health -related
risks .
