Objective: To examine the presence of body image concerns, drive for muscularity, and disordered eating behaviors in collegiate student-athletes., Participants: One hundred and one NCAA Division I student-athletes participated in Phase I; 15 of these also participated in Phase II., Methods: This study employed a mixed method, sequential explanatory design. Participants first completed survey measures assessing body image concern, drive for muscularity, and eating behaviors. These results influenced open-ended, semi-structured interviews, which were thematically analyzed., Results: Body image and disordered eating behaviors were of greater concern than drive for muscularity. Student-athletes reported engaging in eating behaviors as opposed to not eating, yet these eating behaviors trended toward disordered behaviors such as obsessive "healthy eating" or orthorexia., Conclusions: This study took a novel methodological approach to examining student-athlete body image and eating behaviors. Results emphasize the need for further support and education for student-athletes around body image and eating behaviors.

Background: The causes of obesity are multifactorial, with genetic, environmental, behavioural and societal contributions. These factors also affect adherence to diet and exercise after bariatric surgery. The objective of this study was to evaluate changes in perceived obesity-related stigma, exercise and dietary adherence perioperatively as well as what demographic factors most influence the magnitude of these changes., Methods: Validated questionnaires regarding perception of stigma and adherence to diet and exercise regimens were administered to 104 bariatric surgery patients preoperatively and postoperatively at three, six and 12 months. Scoring was compared for improvement, and concomitant factors were analysed for effect on magnitude of improvement., Results: Our study found overall improvement in perception of stigma as well as adherence to diet and exercise regimens. Those with a family history of obesity had less robust improvement compared to those without a family history of obesity. Those who were Caucasian also did not have as robust of an improvement in their scores., Conclusions: Patient perception of obesity-related stigma and adherence to diet and exercise regimens improve after bariatric surgery. However, a patient with a family history of obesity and/or a Caucasian ethnicity may have a less robust improvement in these facets.

Background: Ads depicting models promoting calorie-dense foods and beverages are ubiquitous and no known research has examined their effects on consumers. Drawing from social comparison theory, we hypothesized that participants who viewed ads with models (versus without models) would be more likely to rate models and less likely to rate themselves as able to consume the calorie-dense foods regularly and still maintain their weight/shape. We also hypothesized that participants who viewed ads with models (versus without models) would report more body dissatisfaction and, consistent with consumer research, a greater intention to purchase the product., Methods: Participants (N = 168) were randomly assigned to view food or beverage ads with models or without models and completed self-report measures., Results: Participants who viewed ads without models were more likely to rate themselves and most people as able to consume calorie-dense foods regularly and maintain their weight/shape and reported a greater intention to purchase the product. Consistent with our hypotheses, participants who viewed ads with models reported increased body dissatisfaction., Conclusions: Results indicate that consumers' perceptions of their own and others' abilities to regularly consume calorie-dense foods and maintain their weight/shape change based on whether (or not) the calorie-dense foods are promoted by a model. Our findings reveal the nuanced negative effects of calorie-dense food ads with and without models and give insight into the psychological and potential physical health consequences that food ads can have on consumers.

Purpose: This study aimed to develop and validate the Girls' Disinclination for Physical Activity Scale (G-DAS)and implement the scale along with an objective measure of physical activity (PA) in a longitudinal sample of adolescent girls., Methods: Participants were non-Hispanic White girls who were assessed at ages 13 years (n=151) and 15 years (n=98). Girls completed the G-DAS and the Physical Activity Enjoyment Scale and wore an accelerometer for 7 days., Results: Results supported a five-factor solution for the GDAS;factors represented reasons for disliking PA including low perceived competence, lack of opportunities, high perceived exertion, concern about physical appearance,and threats to girls' gender identity. Data supported the reliability and validity of the G-DAS. Low perceived competence was the most common reason girls reported disliking PA and predicted a decreased likelihood of maintaining sufficient PA across ages 13 to 15 years., Conclusion: Developing PA-related skills prior to adolescence may reduce declines in adolescent girls' PA.

Background: Efforts toward increasing participation in physical activity to prevent and treat overweight and obesity have as yet proved unsuccessful. Among the many barriers that discourage participation are weight-related stigmas. The primary purpose of this study was to explore the relationship between consciousnesses of weight-related stigma and perceived competence in physical activity. A secondary purpose of the study was to explore the potential mediation effects of body esteem and body mass index (BMI) on the relationship. Consciousness of weight stigma, body esteem, and BMI are explored as predictors of perceived competence in physical activity., Methods: Participants included 76 adults who were enrolled in a weight management program. Data were collected using self-administered questionnaires. Path modeling was used to assess the relationships between stigma consciousness and perceived physical activity competence, and the potential mediation effects of BMI and body esteem., Results: Tests indicated that body esteem, but not BMI, mediated the relationship of consciousness of weight-related stigma and perceived physical activity competence., Conclusions: Consciousness of weight stigma, regardless of objective weight status, may negatively affect individuals' willingness to participate in physical activity. Findings such as these are important in furthering understanding the factors that affect behavior, and subsequently conducting programs to overcome perceptions of weight and physical activity to encourage participation., (Copyright 2010 S.

Objective: This study examines developmental change and intraindividual stability in girls' fat stereotypes and associations between girls' internalization of stereotypes and their psychosocial well-being., Methods and Procedures: Participants included 163 non-Hispanic white girls. Girls' fat stereotypes were assessed at ages 9 and 11 years and their height and weight and all measures of psychosocial well-being, including global self-worth, perceived physical appearance, and maladaptive eating attitudes, were assessed at ages 9, 11, and 13 years. Change in girls' fat stereotypes between ages 9 and 11 was assessed using Repeated Measures ANOVA. Intraindividual stability in stereotypes was assessed using Spearman rank correlation analysis. Planned comparisons were used to test the hypothesis that overweight girls who internalize fat stereotypes are at heightened risk of poor psychosocial well-being., Results: Girls' fat stereotypes decreased significantly between ages 9 and 11. Moderate intraindividual stability was observed in overweight girls', but not nonoverweight girls', reported stereotypes. As predicted, overweight girls who reported high fat stereotypes reported significantly lower psychosocial well-being than all other girls in the sample, independent of their weight status., Discussion: Findings suggest that overweight girls may be particularly sensitive to weight-based stereotypes and may experience poor psychosocial well-being when they internalize stereotypes. Health practitioners working with overweight girls need to be aware of girls' sensitivity to weight-based stereotypes and should actively work against condoning and reinforcing such stereotypes.

Purpose: For decades, researchers have proclaimed the positive psychosocial benefits of participation in physical activity. However, recent meta-analyses of the literature have found infrequent and inconclusive empirical support for the link between physical activity and psychosocial well-being. In this study, we use data from a longitudinal study to explore the links between participation in physical activity and global self-esteem among girls from childhood into early adolescence and the direction of this relationship., Methods: Participants included 197 non-Hispanic white girls. Girls' participation in physical activity and their global self-esteem were assessed when they were 9, 11, and 13 years old. Panel regression was used to assess the lagged effect of physical activity on self-esteem and the lagged effect of self-esteem on physical activity, controlling for family socioeconomic status (SES) and girls' body mass index (BMI)., Results: A significant lagged effect of physical activity on self-esteem was identified. Specifically, higher physical activity at ages 9 and 11 years predicted higher self-esteem at ages 11 and 13 years respectively, controlling for covariates. Positive effects of physical activity on self-esteem were most apparent at age 11 and for girls with higher BMI. No support was gained for the lagged effect of self-esteem on physical activity., Conclusions: Results suggest that participating in physical activity can lead to positive self-esteem among adolescent girls, particularly for younger girls and those at greatest risk of overweight. These findings highlight the necessity of promoting physical activity among adolescent girls as a method of fostering positive self-worth.

Background: This study examines whether associations between activity-related support and adolescents' physical activity differ for adolescents at high versus low risk of physical inactivity., Methods: Participants included 202 middle-school-aged girls (N = 92) and boys (N = 110). Physical activity was assessed using three self-report questionnaires. Activity-related support from mothers, fathers, siblings, and peers was assessed using the Activity Support Scale. Perceived sport competence was assessed using the Physical Activity Self Description Questionnaire. Participants' height and weight were measured and used to calculate their age- and sex-adjusted Body Mass Index percentile. Participants were classified as being at high risk for physical inactivity if they fulfilled two of the following three criteria: (1) overweight; (2) female; or (3) having low perceived sport competence., Results: Activity-related support from all sources was associated with higher levels of physical activity among adolescents. A stronger association between activity support and physical activity was found for adolescents at high risk for physical inactivity in comparison to adolescents at low risk., Conclusions: Findings from this study suggest that the activity-related support from family and friends may be an effective tool in promoting physical activity among youth at risk of physical inactivity.
