METHODS The primary objective of this review was to examine the evidence related to(More)
BACKGROUND Previous research has documented that self-objectification is associated with numerous negative outcomes including body shame, eating disorder (ED) pathology, and negative affect. This exploratory open study investigated whether or not an evidence-based body image improvement program that targets thin-ideal internalization in university women(More)
BACKGROUND Childhood obesity is a growing problem, particularly in rural, Louisiana school children. Traditionally, school-based obesity prevention programs have used a primary prevention approach. Finding methods to deliver secondary prevention programs to large numbers of students without singling out overweight students has been a challenge. An(More)
OBJECTIVE Rates of obesity among children have been rising in recent years. Information on the prevalence of obesity in children living in rural communities is needed. We report the prevalence of overweight and obesity in children enrolled in grades 4 to 6 who live in rural areas of Louisiana, USA. METHODS AND PROCEDURES These data were collected as(More)
BACKGROUND Caloric restriction (CR), energy intake reduced below ad libitum (AL) intake, increases life span in many species. The implications for humans can be clarified by randomized controlled trials of CR. METHODS To determine CR's feasibility, safety, and effects on predictors of longevity, disease risk factors, and quality of life in nonobese humans(More)

Childhood obesity prevention trials suggest that, on average, overweight/obese children lose body weight and nonoverweight children gain weight. This investigation tested the(More)
OBJECTIVE To develop a prototype of the Body Morph Assessment (BMA), and to test the reliability and validity of this new measure of body image. The BMA is a realistic and relatively simple procedure that uses computer morphing for the assessment of body image. For the purposes of this preliminary study, a prototype of the BMA was developed for usage with(More)
