Abstract : There is an increasing awareness regarding breakfast skipping, duration of sleep, and sleep timing effects on body mass index. The current study aimed to assess breakfast skipping, duration of sleep, and sleep timing effects on body mass index among high school students in Tabuk, Saudi Arabia. This cross-sectional study was conducted among 1640 randomly selected high secondary school male students in Tabuk City during the period October 2019 to April 2020. Participants were asked to sign a written informed consent then interviewed to collect demographic data, frequency of breakfast intake, sleep duration and sleep timing during working days and weekends, the participant's weight and height were measured to calculate the body mass index. The chi-square test was used to compare obese, overweight, and underweight students regarding breakfast skipping, sleep duration, and timing. A P-value<0.05 was considered significant. The ethical committee of the University of Tabuk approved the research. Participants (age 17.75±1.40), 44.8% were breakfast-skippers, 27% were either obese or overweight, while underweight was evident in 19%. In the present study, 41.2% sleep <8 hours/night, 51.2% and 97.5% used to sleep later than midnight during weekends and weekends respectively. Obesity was commoner among breakfast skippers (20.6% vs. 14.5%), P-value <0.05, no significant differences was evident between obesity, overweight, and underweight regarding sleep duration, and sleep timing during the weekdays and weekends. Obesity was commoner among breakfast skippers, with no differences between obese, overweight, and underweight regarding sleep duration and timing.
