Background: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also…

With the increase of childhood obesity and sedentary behavior, it is essential to discover innovative ways to motivate youth to be more active. Many Hispanic children in the United States in obesogenic environments particularly lack opportunities for physical activity (PA). Exergames (i.e., motion-based video games) may enhance PA among at-risk…

To assess the prevalence of weight misperception in American adolescents and its association with diet and physical activity behaviors, "Youth Risk Behavior Survey" data were utilized for this study. Based on reported and perceived weight, adolescents in the study were grouped into four categories (true negative [52.4%] = normal body…

Much is known about the influence of potential lifestyle factors on adolescents' nutritional status, but in Croatia there are not many studies of this topic. Past studies have shown many variables associated with being overweight/obese. Thus, this study investigated the associations between the overweight/obesity status and lifestyle factors of…

Little is known about the correlates of physical activity and sedentary behavior in Hispanic adolescents. This study examined at baseline and 2-year follow-up: (1) the relationship between self-efficacy for physical activity and physical activity, (2) the association of weight perception with physical activity and sedentary behavior, and (3)…

This report, from researchers at ChildObesity180, an initiative of the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University, explores the impact of the Boston Foundation's investment in four nonprofits that provide structured physical activity to students. The report finds that investments in "Build Our…

Background: We examined the body mass index (BMI) of students attending Seventh-day Adventist (Adventist) schools in Australia in 2001 and 2012. Methods: A total of 3069 students attending Adventist schools in Australia responded to a health and lifestyle survey in 2001 (N = 1335) and 2012 (N = 1734). The survey captured self-reported height and…

Education and training in schools are essential elements in the development and socialization process of children from early childhood. The fact of considering health as a complete physical, mental and social wellbeing (World Health Organization (1848), WHO), and not only as the absence of illness, is closely related to the achievement of optimal…

Approximately one in three preadolescents (34%) is obese/overweight and one in four (25%) experience a mental health issue. Urban youth suffer from higher rates of these problems, and at earlier ages than their peers. This study's purpose was to determine feasibility/acceptability and preliminary effects of the COPE (Creating Opportunities for…

[For "[West Virginia Youth…

Background: Income disparities in US youth in academic achievement appear to widen during the summer because of discontinued learning among children from lower-income households. Little is known about whether behavioral risk factors for childhood obesity, such as diet and physical activity, also demonstrate a widening difference by income when…

This collection of fact sheets includes: (1) Alcohol and Drug Use; (2) Bullying and Suicidal Behaviors; (3) Dietary Behaviors; (4) Disease Prevention and Health Care Access; (5) Injury Risk and Violence; (6) Physical Inactivity; (7) Sexual Behaviors; (8) Tobacco Use; and (9) Weight Management. [For "[West Virginia Youth Risk Behavior/School…

Objective: A recent economic approach suggests that people do not account for the long-term implications of unhealthy behaviours, preventing them from performing a fully rational trade-off between current benefits and future costs, leading to negative health outcomes. We examined whether the current allocation of time to physical activity among…

Background: We evaluated the 12-month effects of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, Nutrition) program versus an attention control program (Healthy Teens) on overweight/obesity and depressive symptoms in high school adolescents. Methods: A cluster randomized controlled…

Objective: The aim of this study was to explore parental perceptions of adolescent health behaviours and to examine to what extent parents' perceptions of their children's health behaviours are determined by the family's socio-demographic characteristics. Method: Participants in the study were 605 parents. They completed questionnaires in which…
