Sleep Duration, Mental Health, and Increased Difficulty Doing Schoolwork Among High School Students During the...

We estimated the prevalence of short sleep duration (<8 h/average school night) among high school students (grades 9-12) during the COVID-19 pandemic by using data from the Adolescent Behaviors and Experiences Survey (January-June 2021; N = 7,705). An adjusted logistic regression model predicted prevalence ratios for more difficulty doing schoolwork during the pandemic compared with before the pandemic. Most (76.5%) students experienced short sleep duration, and two-thirds perceived more difficulty doing schoolwork. Students who slept less than 7 hours per school night or experienced poor mental health were more likely to report increased difficulty doing schoolwork. Addressing students' sleep duration could complement efforts to bolster their mental health and learning.
