This study considered the interrelationships among biological maturation and its physical correlates, social physique anxiety, and appearance-related physical self-perceptions in 113 adolescent female figure skaters participating in solo (n = 73) or partner contexts (n = 40). Participants were interviewed about their menarcheal status, underwent a…

In this study we examined self-reported suicide attempts and their relationship to other health risk factors in a community sample of 16,644 adolescents. Fifteen percent endorsed suicide attempts (10% single; 5% multiple attempts). We hypothesized that multiple attempters would show higher prevalence of comorbid health risks than single or…

Little research has investigated sociocultural factors in the development of body dissatisfaction in preadolescent girls. This study examined the combined influence of media and peer factors. The participants were 100 girls aged nine to 12 years. The girls completed questionnaire measures of media exposure (television and magazines), peer…

The body mass index (BMI), or the ratio of weight in kilograms to the square of height in meters, is widely used to determine the presence or absence of overweight and obesity in adults. Although many consider BMI an acceptable clinical surrogate of body fatness, it does not differentiate between fat and fat-free tissues. Thus, children and…

A lifespace has to do with how selves are mediated by combining multiple cultural symbols to construct an identity in the world. The authors cite examples from media texts, as well as from a narrative study conducted with 10 adolescent girls in a treatment program for eating disorders, that illustrate the importance of practitioners considering…

The validity of estimates of peak oxygen consumption (VO[subscript 2]peak) using submaximal exercise tests may be compromised when the participants being tested are not similar to the participants used to develop the test. This study compared ethnic differences in the heart rate (HR) and oxygen consumption (VO[subscript 2]) responses to submaximal…

The physical educator's role is evolving into that of a teacher who is well educated in the areas of teaching, skill acquisition and development, motor learning, exercise physiology, physical conditioning, weight management, health, and lifestyle management. In an era when childhood obesity is at an all-time high, body composition can be one…

Prader-Willi syndrome is a multisystem neurogenetic obesity disorder with behavioral manifestations, including hyperphagia, compulsive behavior, self-injury, and mild to moderate mental retardation. In an 8-week open-label study, we evaluated adjunctive therapy with the anticonvulsant topiramate in 8 adults with Prader-Willi syndrome. Appetite was…

This study compared the effect of physical activity and obesity on academic achievement and was based on the premise that the health of a child has an effect on his or her ability to learn and to achieve academically. Specifically, health-related topics of inactivity and obesity were considered. The participants included 12,607 third grade…

Canadian data from the 1998 Cross-National Survey on Health Behaviors in School-Aged Children were analyzed to examine the effects of school experiences on personal health (physical health, mental health, self-esteem, helplessness, and body image) and interpersonal relationships (number of close friends and making friends) among adolescents.…

The purpose of this study was to test a conceptual model based on theoretical and empirically supported relationships related to the influences of weight perceptions, weight concerns, desires to change weight, friends, age and location in relation to physical activity (PA) and smoking in adolescents. A total of 1242 males and 1446 females (mean…

Though leanness in athletes is often a natural state, it can pose long-term liability to some athletes' performance and/or health. The physician must determine when leanness is reason for clinical concern. Athletes who do not eat enough to sustain training must either reduce the exercise load or increase nutritional intake.

Reports a study of postmenopausal women's practice of exercise after age 30. Subjects (n=111) were studied with regard to their practice of weight-bearing, aerobic, regular, and area specific exercise. Findings indicated that regular practice (at least 90 minutes weekly) of weight-bearing, aerobic, and regular exercise affected the development of…

The goal of this study was to evaluate the relationships between self-reported and measured height, weight, and body mass index (BMI) in a sample of eighth-grade students. The study population consisted of eighth-grade students in eastern North Carolina who completed a cross-sectional survey, self-reported their height and weight, and had their…

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO[subscript 2]max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO[subscript 2]max (M = 39.96 mL[middle dot]kg[superscript -1][middle…
