Although research studies have not demonstrated conclusively that American children are less fit than in the past, solid evidence does exist that they are more fat. Childhood obesity is a major public health problem. (IAH)

Examined whether 132 preschool children who varied in levels of body fat differed on psychosocial functioning. Children did not differ in self-esteem and family functioning as function of body fat. Prospectively, physical self-esteem weakly but significantly correlated with body fat at one and two years; father's perception of family functioning…

Determined the influence of a heavy-load bench press on indicators of upper-body power during an explosive pushup, examining the influence of a set of 5 repetitions of 5 repetition maximum (RM) bench press preceding explosive pushups. There were no significant differences for any of the force platform data when explosive pushups were preceded by…

Let K be a compact subset of the interior of the unit disk D in the plane and suppose one can't see through the boundary of D and identify K. However, assume that one can take "topological X-rays" of D which measure the "density" of K along the lines of the X-rays. By taking these X-rays from all directions, a "topological MRI" is generated for…

Objective: The purpose of this study was to establish baseline values on physiological parameters for 7-11 graders (n = 146) in a rural area of Alabama and to examine whether differences existed among the adolescents in the county. Design: Descriptive. Setting: Many adolescents in the southern portion of the United States suffer disproportionately…

Recent research suggests that racial residential segregation may be detrimental to health. This study investigates the influence of neighborhood racial isolation on obesity and considers the role of neighborhood disorder as a mediator in this relationship.

About one half (54.0%) purchased lunch [greater than or equal] 2…

This article investigates (i) how the structuring practices and meanings associated with dance classes at an inner-city American high school operated as institutional spaces (re)producing "dividing practices" that supported racial and classed hierarchies; (ii) how these racist structures were created and maintained relative to dominant notions of…

Background: Although the effects of nutrition on health and school performance are often cited, few research studies have examined the effect of diet quality on the academic performance of children. This study examines the association between overall diet quality and academic performance. Methods: In 2003, 5200 grade 5 students in Nova Scotia,…

Background: This study examined physical activity (PA) levels of overweight and nonoverweight African American and Caucasian students (n = 198) during game play in physical education classes. Methods: Body fat percentages (%BFs) were determined using the skinfold technique and Slaughter et al prediction equations. Girls were classified as…

In this article we examine the importance of sensation seeking and pragmatism in the steroids and sports supplements behavior and attitudes of high school and junior high school students on Long Island, New York.
