Objective To identify independent associations screen time categories, between body mass index (BMI) obesity in adolescents. Design, Setting, Participants This...
To determine associations between bedtime screen time behaviors and sleep outcomes in a national study of early adolescents.
Abstract Background To assess the prevalence of various media parenting practices and identify their associations with early adolescent screen time problematic social media, video game, mobile phone use. Methods Cross-sectional data from Year 3 Adolescent Brain Cognitive Development (ABCD) Study (2019–2022) that included 10,048 adolescents (12–13 years, 48.3% female, 45.6% racial/ethnic minorities) in US were analyzed using multiple linear regression analyses adjusting for potential...
Abstract Background According to the Physical Activity Guidelines Advisory Committee Scientific Report, limited evidence is available on sedentary behaviors (screen time) and their joint associations with physical activity (steps) for cardiovascular health in adolescence. The objective of this study was identify screen time categories disease (CVD) risk factors (blood pressure, hemoglobin A1c, cholesterol) Methods This analyzed data from Adolescent Brain Cognitive Development (ABCD) Study,...
Screen time has been reported to be associated with binge-eating disorder (BED) among adolescents in the US; however, potential mediators remain unclear. This study aimed evaluate depression symptoms as a mediator of prospective association between screen and BED.
Abstract Objective To assess whether specific parent media practices are associated with the consumption of R-rated (restricted) movies and mature-rated video game use in early adolescents. Methods Data from Adolescent Brain Cognitive Development (ABCD) Study ( N = 10,054, 12–13 years, Year 3, 2019–2021) were analyzed. Ordinal logistic regression models used to associations among parenting or use, adjusting for potential confounders. Results Parental allowance bedroom screen (adjusted odds...
To estimate associations between sociodemographic factors and cardiometabolic risk among a demographically diverse sample of U.S. adolescents aged 10-14 years. This study analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 1412), Years 2 3 (2018-2021). Cardiometabolic including hemoglobin A1c cholesterol (total (TC), high-density lipoprotein (HDL-C), non-HDL-C) were assessed. Multivariable linear regression models conducted to (age, sex, race ethnicity, household...
Abstract Study Objectives Adequate sleep is essential for adolescents' physical, emotional, and cognitive well-being. However, accurately capturing the complex components of in this demographic challenging, especially with retrospective self-report measures. This study aims to compare data obtained from youth reports, caregiver Fitbit devices among early adolescents. Methods Data 11,879 adolescents (11−14 years, 47.83% female), Year 2 Adolescent Brain Cognitive Development (ABCD) Study, were...
During the COVID-19 pandemic, adolescents and families have turned to online activities social platforms more than ever maintain well-being, connect remotely with friends family, schooling. However, excessive screen use can negative effects on health (e.g., sleep). This study examined changes in sleep habits recreational time (social media, video gaming), their relationship, before across first year of pandemic Adolescent Brain Cognitive Development (ABCD) Study.
Abstract Sociodemographic and lifestyle factors (sleep, physical activity, sedentary behavior) may predict obesity risk in early adolescence; a critical period during the life course. Analyzing data from 2971 participants (M = 11.94, SD 0.64 years) wearing Fitbit Charge HR 2 devices Adolescent Brain Cognitive Development (ABCD) Study, glass box machine learning models identified predictors Fitbit-derived measures of sleep, cardiovascular fitness, sociodemographic status. Key include...
Abstract Youth screen media activity is a growing concern, though few studies include objective usage data. Through the longitudinal, U.S.-based Adolescent Brain Cognitive Development (ABCD) Study, youth (m age = 14; n 1415) self-reported their typical smartphone use and passively recorded three weeks of via ABCD-specific Effortless Assessment Research System (EARS) application. Here we describe validate passively-sensed keyboard app measures, provide code to harmonize measures across...
To determine the association between cyberbullying (victimization and perpetration) sleep disturbance among a demographically diverse sample of 10-14-year-old early adolescents.
Objective In this study, we describe the rationale, supported by preliminary data, for a novel, digital, immersive virtual reality (VR)-based mind–body approach, designed to reduce bedtime arousal in adolescents with insomnia. Methods Fifty-two high-school students (16–20 years; 32 female) ( N = 18) and without 34) DSM-5 insomnia symptoms engaged 20 min of VR-guided meditation paced breathing (0.1 Hz) intervention condition) quiet activity control condition), right before bedtime, on two...

The menstrual cycle is a loop involving the interplay of different organs and hormones, with capacity to impact numerous physiological processes, including body temperature heart rate, which in turn display rhythms. advent wearable devices that can continuously track data opens possibility using these prolonged time series skin noninvasively detect variations occur ovulatory cycles. Here, we show variation better represented by model oscillation, cosinor, than biphasic square wave model. We...
