Background: Four-day school week (FDSW) use has increased substantially among US districts in recent years, but limited data exist on health impacts of this school schedule. This study examined associations of reduced school exposure via FDSWs with adolescent health and risk behaviors, obesity, and food security. Methods: Self-report data from…

Childhood obesity is a prevalent health condition, the effects of which extend to mental health, social relationships, educational performance, and long-term physical health conditions. The present study focused on an optimized student support intervention that functions in predominantly high-poverty urban locations, which recognizes students as…

Background: "Choose Health: Food, Fun, and Fitness" (CHFFF) is aimed at 3rd to 6th graders, and uses experiential learning, food preparation, active games, goal setting, and a family newsletter to target behaviors shown to decrease childhood obesity and chronic disease risk. This study aimed to evaluate CHFFF as intended in low-income…

Background: Embedded within children's weight trajectories are complex environmental contexts that influence obesity risk. As such, the normative environment of body mass index (BMI) within schools may influence children's weight trajectories as they age from kindergarten to fifth grade. Methods: I use 5 waves of the ECLS-K--Kindergarten Class…

Background: This was a cross-sectional survey to investigate the relationship of age, parent education, sleep duration, physical activity, and dietary habits with overweight or obesity in school-age children in Shanghai. Methods: The survey gathered information from 13,001 children in grades 1 through 5 (age 6 to 10 years) among 26 elementary…

The Tennessee Department of Education's office of coordinated school health (CSH) works with every school district in the state to address all aspects of student health, with a special emphasis on reducing Tennessee's childhood obesity rates. Encouraging adequate physical activity and providing physical education for all students are the central…

Background: We examined prevalence, incidence, and trajectory of obesity from kindergarten through grade 8 in one of the first states to implement annual surveillance. Methods: Participants included 16,414 children enrolled in kindergarten in Arkansas in 2004 with complete body mass index (BMI) measurements in kindergarten and eighth grade.…

Background: South Africa has a high prevalence of HIV and obesity. Interventions to date have primarily focused on adolescents and adults. Prevention of obesity, in particular, is not addressed substantively in the current pre-adolescent school curriculum. Education about factors underlying these issues early in life could reach beyond children,…

Background: Body mass index (BMI) increases when students are away on summer vacation. Evaluation of serial BMI measurements on year-round students allows new insight into the reasons children gain weight seasonally. Methods: The 206 first and second graders of 2-year-round elementary schools with obesity intervention programs were weighed and…

Background: Childhood obesity is a significant but largely "modifiable" health risk, disproportionately affecting socioeconomically disadvantaged, racial/ethnic minority, and rural children. Elementary school-aged children typically experience the greatest increases in excess weight gain and therefore are important targets for reducing…

The Tennessee Department of Education's office of coordinated school health (CSH) works with every school district in the state to address all aspects of student health, with a special emphasis on reducing Tennessee's childhood obesity rates. Encouraging adequate physical activity and providing physical education for all students are the central…

Purpose: Evidence indicates that active school travel (AST) including walking can effectively lower levels of obesity among school-age children. Yet Queensland has been identified as one of the most inactive states in Australia where only 5 per cent of Years 1 and 5 children engaged in AST on a daily basis. The purpose of this paper is to explain…

Encouraging adequate physical activity and providing physical education for all students are the central…

Objective: Childhood obesity represents a significant public health problem. This study examined physical activity and nutrition behaviours and attitudes of 9-11-year-olds, and factors influencing these behaviours. Design: Study participants recorded pedometer steps for 7 days and completed physical activity enjoyment, food attitudes and food…

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…
