. The aim of this study was to identify lifestyle habits that contribute to night sleep reduction in the Kuwaiti population. . Children were 10 to 12 years old and were approximately equally distributed among 138 elementary schools representing the 6 governorates of Kuwait. In the first phase of the study, data were collected from 8317 children. The same data were collected 2 years later from 6316 of the children from the first phase of the study. Calibrated examiners conducted sleep evaluation, lifestyle habits interviews, and body weight measurements. A multilevel random intercept and slope model was conducted to determine the effect of screen-based activities on the daily night sleep hours at 3 levels: within schools, among children, and over time. The primary dependent variable was the number of daily sleep hours. Independent variables assessed were lifestyle habits including screen-based activity variables including TV and video game use. . Screen-based activities were significant factors that reduced daily sleep hours (P < .05). There were statistically significant variations between schools and children over time. Conclusion. Longitudinal analysis of Kuwaiti children revealed that TV and video game use were major risk behaviors contributing to decreased sleep duration with strong clustering effect of the observations within schools across time.

What Is Already Known About This Topic?: The prevalence of insufficient physical activity (PA) among Chinese adults has shown an upward trend, reaching 22.3% in 2018. Leisure time PA (LTPA) constitutes a minimal proportion of total physical activity patterns.

Background: This study aimed to compare the prevalence of excess weight in adolescents living in Florianópolis, Santa Catarina, Brazil, from 2007 to 2017/2018 and assess associations with physical activity level, screen time, muscle strength, and cardiorespiratory fitness.
Methods: Two cross-sectional surveys were conducted with adolescents (14 to 19 years old). The body mass index was calculated from measurements of body weight (kg) and height (m2).

Background: Recent research suggests that children spend increasing amounts of time engaging in screen-based activities and less time outdoors in natural environments. There is a growing body of theory-driven literature evidencing that child screen use and exposure to nature are associated with wellbeing outcomes in contrasting ways. However, few studies have explored their combinative effects, and the relational family context has been largely overlooked.

Exercise is a powerful tool for disease prevention and rehabilitation. Commercially available virtual reality (VR) devices and apps offer an immersive platform to gamify exercise and potentially enhance physiological and psychological benefits. However, no work has compared immersive exercise to closely matched 2D screen-based equivalents with the same visual and auditory stimuli.

Aim: A worry regarding young people's physical activity engagement relates to a potentially competing development: the role of screen-based media (SBM) in their everyday lives. The present study aimed to assess time spent on different types of SBM, self-reported moderate-to-vigorous physical activity (MVPA) and physical activity in different domains and their interrelations.
Methods: The study is based on data from 3737 participants aged 11, 13 and 15 years from Norway collected in 2021/2022 as part of the Health Behaviour in School-aged Children collaborative cross-national survey.
