Weekday-to-weekend sleep discrepancy is a common phenomenon in school-age children and youths. However, the effects of weekday-to-weekend sleep differences remain unclear. A systematic review that included 72 observational studies was conducted to examine the association of weekday-to-weekend differences in bedtime, rise time, mid-point of sleep and sleep duration with academic performance and health-related outcomes in children and youths. Weekday-to-weekend difference in sleep timing (e.g., bedtime) was associated with poorer academic performance and depressive symptoms in in youths, particularly secondary school students, and a higher risk of substance use as well as overweight/obesity in the overall samples. In addition, weekday-to-weekend difference in sleep duration showed a modest association with poorer academic performance and depressive symptoms in the overall samples, as well as a higher risk of overweight/obesity, particularly in Asian children and youths. Albeit limited evidence, greater sleep differences were related to an increased risk of behavioral problems and suicidality. Findings on the associations between weekday-to-weekend sleep differences and specific cognitive abilities, anxiety, and cardiometabolic risks were limited and inconclusive. Longitudinal and experimental studies utilizing objective sleep measures are recommended to further examine the impacts of weekday-to-weekend sleep differences on mental and physical health, and to gain more insight into the mechanisms underlying their associations.

Objective: To evaluate whether social jet lag (SJL) and weekend catch-up sleep (CUS), proxies of circadian misalignment, were associated with BMI and chronic conditions.
Methods: Participants (n = 2,050,18-65y) were part of a virtual cross-sectional and population-based research. We examined CUS and SJL as continuous and categorical (< 1 h,1-2 h, > 2 h).

The sleep difference between weekdays and weekends can lead to negative physical and mental health outcomes in adolescents. Thus, this study has attempted to analyze the impact of sleep time differences on various health outcomes, using nationally representative panel data. Data from the junior high school student panel of the Korean Children and Youth Panel Survey were analyzed.

Objectives: Discrepancy in weekday-weekend sleep induces negative effects on physical health, obesity, psychological disorders, and academic performance; this particularly affects adolescent students through extracurricular tutoring, including evening self-study, private tutoring, and home studies. The present research aimed to clarify sociodemographic and economic factors, including extracurricular tutoring time, associated with weekday-to-weekend sleep differences using longitudinal data.
Study Design: Data from the Korean Children and Youth Panel Survey (KCYPS) data were analyzed.

Objectives: To investigate the relationship between differences in weekday-to-weekend sleep habits and stress responses in a working population.
Methods: This cross-sectional study used data from university workers on sleep habits, differences in sleep duration between weekdays and weekends, and each midpoint of the sleep phase on weekdays and weekends. Social jetlag was defined as the difference in the midpoint of the sleep phase between weekdays and weekends.

In this study, we examined patterns of obesity, physical activity (PA), sleep, and screen time in urban American Indian (AI) youth in the 6-8 grade. A youth sample (N = 36) from 3 middle schools was recruited to participate in this observational sample of convenience. Youth completed a demographic and screen time survey, measurements of height and weight, and wore a wrist accelerometer continuously for 7 days to assess PA and sleep.
