This study used daily experimental data from smart bands worn by 142 respondents to investigate the relationship between the number of minutes slept and self-reported mood. The results showed that more minutes of sleep were associated with improved mood. Time preferences, altruism, and trust were also associated with mood. Finally, our analysis…

Lifestyle risk behaviours--physical inactivity, poor diet, poor sleep, recreational screen time, and alcohol and tobacco use--collectively known as the "Big 6" emerge during adolescence and significantly contribute to chronic disease development into adulthood. To address this issue, the Health4Life program targeted the Big 6 risk…

Background: We aimed to characterize relationships between delayed high school start time policy, which is known to lengthen school night sleep duration, and patterns in activity outcomes: physical activity, non-school electronic screen time (non-schoolwork), and sports and extracurricular activity among adolescents. Methods: We used data from the…

Numerous studies have reported a disruption in the lifestyle habits (LsHs) of post-secondary students during the COVID-19 pandemic. Given the importance of LsHs for these young adults' physical and mental health and academic success, it is pertinent to examine whether these changes were maintained beyond the public health crisis. As post-pandemic…

Objective: Determine the temporal and spatial characteristics of stairs versus elevator use in a university residence hall to inform future physical activity promotion efforts. Participants: All residents and visitors for a single, four-story residence hall dormitory building located on a college campus in Orange, CA. Methods: Smart mat systems…

Objective: Examine effects of self-affirmation on university students' processing of health risk messages related to sedentary behavior. Participants: Eighty-eight students from a Canadian university (females = 53; males = 35; M[subscript age] = 21.74, SD = 5.36) participated during the 2018-2019 academic year. Methods: Participants were…

Background: Schools play a vital role in student health, and a collaborative approach may affect health factors such as physical activity (PA) and nutrition. There is a lack of recent literature synthesizing collaborative approaches in K-12 settings. We present updated evidence about interventions that used a coordinated school health approach to…

Background: School-based health education can provide students with learning experiences that improve knowledge, attitudes, and perceptions (KAP) and behaviors regarding physical activity and nutrition. Methods: We conducted a 2-phase systematic review. Phase 1 was a review of reviews (ie, systematic reviews or meta-analyses) that were published…

Research recognizes that physical activity habits developed earlier in life are likely to be continued throughout life. To combat rises in obesity rates and declining physical activity levels among adults, studies emphasize the responsibility higher education institutions have in targeting young adult's physical activity habits. Theories of…

This empirical cross-sectional study explored the effect of chronotypes on classroom behaviour. One hundred and forty young Portuguese children, from 1st to 4th grades, were examined regarding their chronotype and disruptive behaviours occurring in the classroom. Three groups of chronotypes (i.e., morning, intermediate and evening) were…

For undergraduate students, excessive screen time is associated with poorer mental health and greater perceived stress. Objective: The purpose of the present investigation was to determine the potential moderating influence of physical activity and sleep on the relationship between screen time and stress. Participants & Methods: A…

This article discusses concepts related to character strengths and positive youth development and how these ideas can be applied to improve outcomes among gifted young people. A theory with roots in public health, The Theory of Triadic Influence (TTI), is discussed with examples applied to gifted populations. Practitioners and researchers from…

In the United States, the Coronavirus Disease 2019 (COVID-19) pandemic necessitated nationwide closures of kindergarten through twelfth grade (K-12) schools. Stay-at-home orders and social distancing mandates were also implemented to mitigate the spread of COVID-19. The purpose of this systematic review was to synthesize the existing literature on…
