An Exploratory Assessment of Sociocultural Attitudes and Appearance Comparison Among Athletes With Physical Disabilities.

This study aimed to assess the internalization of sociocultural attitudes and appearance comparison among U.S. athletes with physical disabilities. Female (n = 19) and male (n = 25) athletes between the ages of 18 and 73 years completed a quantitative survey along with two exploratory open-ended questions related to body appearance and influencers. Results showed significant correlations between internalization of the thin and low-body-fat ideal and appearance comparison (r = .55, p < .05) and internalization of the muscular ideal and appearance comparison (r = .76, p < .05) among women. For men, results showed a significant association between internalization of the muscular ideal and appearance comparison (r = .52, p < .05). The findings prompt further investigation of whether appearance comparison and internalization influence body dissatisfaction and disordered eating among athletes with physical disabilities.

Insomnia, Psychosocial Well-Being, and Weight Control Behaviors Among Healthy-Weight Adolescent Females: Brief Report.

BACKGROUND: Weight control behaviors (WCBs) typically involve appearance- or health-driven behaviors that may be influenced by physiological, psychological, or social factors. Sleep disturbances like insomnia are an important area of research for adolescent populations, as early intervention may result in improvements in other physical and mental health domains. The purpose of this study was to investigate the relationship of insomnia, psychosocial well-being, and current WCBs in healthy-weight female adolescents. METHOD: Female adolescents (N = 323; Mage = 12.33 ± .04) who had healthy body mass index (BMI) levels completed self-report items on insomnia, depression, self-esteem, and physical self-concept. Multivariate analysis of covariance (MANCOVA), controlling for age, was conducted to further examine differences in insomnia and psychosocial variables among the WCB groups. RESULTS: Compared to those who were trying to stay the same weight or not trying to do anything about their weight, the girls who were trying to lose weight had significantly greater insomnia and depression symptoms, and lower self-esteem, with small to medium effect sizes. CONCLUSIONS: Clinicians working with adolescent girls should include assessments of WCBs in addition to measures of insomnia symptoms, even for adolescent girls within a normal BMI range, as these are common and frequently co-occurring phenomena. Additional research is needed to further disentangle these complicated relationships.

Living in a Larger Body: Do Exercise Motives Influence Associations between Body Image and Exercise Avoidance Motivation?

The study explored reasons for exercise as possible mediators of the relationship between body appreciation and exercise avoidance motivation and between body surveillance and exercise avoidance motivation. Using a cross-sectional design, 131 women with a body mass index (BMI) of 25 or higher completed measures of body surveillance, body appreciation, reasons for exercise, and exercise avoidance motivation. Mediation analyses indicated that appearance-oriented reasons for exercise partially mediated the body surveillance-exercise avoidance motivation relationship. Health and fitness professionals, organizations, and environments should avoid reinforcing appearance-oriented reasons for exercise. Rather, empowering exercise experiences and environments should be created as they seem to benefit women regardless of reasons for exercise.

Ecological analysis of college women's physical activity and health-related quality of life.

Despite significant health benefits of regular physical activity, over 60 percent of college women do not meet recommended physical activity guidelines to promote their health and health-related quality of life (HRQoL), a comprehensive construct including physical and psychosocial health functioning. The major purpose of this study was to examine the influences of individual (e.g., self-efficacy, enjoyment), social (e.g., family and friend support), and physical environmental factors (e.g., crime safety) on college women's physical activity and HRQoL. Participants were 235 (Mean age = 21.0 years) college women from a public research university located in the southwest region of the United States. They completed validated surveys assessing their perceptions of physical activity, HRQoL, and social ecological factors during the spring semester of 2012. The findings of three multiple linear regressions, entering individual factors first, followed by social and physical environmental factors, revealed that self-efficacy and crime safety were significantly related to physical activity. For HRQoL-physical functioning, significant factors were self-efficacy, enjoyment, and crime safety. Enjoyment was the only factor related to HRQoL-psychosocial functioning. These findings indicated that physical activity professionals need to foster safe environments, enhance self-efficacy, and provide enjoyable activities to promote college women's physical activity and HRQoL.

Better Health-Related Fitness in Youth: Implications for Public Health Guidelines.

Public health guidelines for physical activity (PA) behaviors are being updated with 2018 as a proposed release date. Currently, ≥60 minutes of daily PA are recommended for youth. Thus, the purpose of this study was to investigate the association between reported days of aerobic PA and health-related fitness (HRF). Participants included 4448 students in grades 6-8. Self-reported days of ≥60 minutes of aerobic PA was obtained. HRF was assessed with FitnessGram. Discriminant analysis indicated that weekly days of aerobic PA related to HRF. Adolescents who participated in ≥5 days of weekly aerobic PA generally had better fitness results than those with ≤4 days. Chi-square analyses indicated the highest percentages of adolescents in the FitnessGram Healthy Fitness Zone™ (HFZ) for each test item were those with ≥5 days of aerobic PA. These findings provided initial support that the impact of aerobic PA on HRF plateaus at 5 days per week. Thus, adolescents may be able to improve HRF even if they do not meet the currently recommended guidelines for daily PA.

Weight Control Behavior as an Indicator of Adolescent Psychological Well-Being.

BACKGROUND: Adolescence is a critical time for the development of psychological well-being. Weight gain and the emergence of body image concerns during this period can lead to the development of negative psychological states. To explore this issue, we examined the relationship between weight control behavior (WCB; ie, trying to lose, gain, stay the same, or do nothing about weight) and levels of depression and self-esteem. METHODS: Adolescents (508 boys, 502 girls; Mage = 12.32 ± .88 years) completed a survey that assessed WCB, depression, and self-esteem. Descriptive discriminant analysis was used to analyze WCB group differences on psychological well-being. Multivariate post hoc analysis further examined group differences. Structure coefficients indicated the relative importance of each dependent variable in boys and girls. RESULTS: Results indicated that, among both sexes, WCB was significantly related to depression and self-esteem. Individuals trying to lose weight had lower levels of psychological well-being than the other groups. CONCLUSIONS: Adolescents trying to lose weight reported the lowest psychological well-being scores whereas those not doing anything to control weight reported the highest levels of psychological well-being. These findings have important implications for screening and education programs designed to monitor and support adolescent psychological well-being.

Development and validation of the intuitive exercise scale.

Up to 80% of individuals with eating disorders engage in dysfunctional exercise, which is characterized by exercising in excessive quantities often past the point of pain as well as compulsive feelings and negative affect when exercise is disrupted (Cook, Hausenblas, Crosby, Cao, & Wonderlich, 2015). Intuitive exercise involves an awareness of the senses while moving and attending to one's bodily cues for when to start and stop exercise, rather than feeling compelled to adhere to a rigid program (Reel, 2015). The purpose of this study was to design a measurement tool to evaluate the construct of intuitive exercise in research, treatment, and prevention settings. The 14-item Intuitive Exercise Scale (IEXS) was developed and validated in the current study with completed surveys from 518 female and male adult participants. Exploratory factor analysis was used to identify four latent constructs, including emotional exercise, exercise rigidity, body trust, and mindful exercise, which were supported via confirmatory factor analysis (CFI=0.96; SRMR=0.06). The IEXS demonstrated configural, metric, and scalar invariance across women and men. Correlations with measures of intuitive eating, exercise dependence, and exercise motivation supported convergent and discriminant validity.

Predictors of obesity bias among exercise science students.

The purpose of the present study was to investigate particular psychosocial predictors of obesity bias in prehealth professionals, which include the internalization of athletic and general body ideals, perceived media pressure and information, and achievement goal orientations. Exercise science undergraduate students (n= 242) filled out a survey containing questions of demographic characteristics, achievement goals, social-cultural attitudes toward appearance (using Sociocultural Attitudes Towards Appearance Questionnaire-3), and obesity bias measurements (using the antifat attitudes test and fat phobia scale). The results indicated that students were explicitly biased toward overweight and obese individuals, held had high task and ego goals, and had high internalization of an athletic body type ideal, as determined by mean scores being above the median values for each scale. Internalization of the athletic body type predicted obesity bias for fat phobia, weight control blame, and physical/romantic attractiveness. In conclusion, exercise science students may enter programs socialized from society and sport, and, potentially, these psychosocial attitudes and beliefs may have implications to working with future clients, especially for those of the general population and those whose body shape and size are different than themselves.

Psychosocial Mediators of the Fitness-Depression Relationship Within Adolescents.

BACKGROUND: A lot of evidence showed that boys and girls are at high risk of developing major or minor depression in adolescence. Increases in physical fitness have been associated with lower levels of depressive symptoms, yet the mechanisms that underlie (or mediate) this relationship have not been thoroughly examined. METHODS: 528 boys (mean age = 12.33 years) and 507 girls (mean age = 12.32 years) drawn from a suburban school district participated. Self-report measures were used to assess the mediators (body satisfaction and social physique anxiety) and the outcome (depression); the Progressive Aerobic Cardiovascular Endurance Run (PACER) in conjunction with age, Body Mass Index (BMI), and sex were used to determine an objective estimate of cardiorespiratory fitness. Path analyses were used to test the proposed models. RESULTS: The effects of fitness on depressive symptoms were mediated through body satisfaction and social physique anxiety; 25% to 35% of the depression variance was explained. CONCLUSION: Boys' and girls' depression scores were based on the extent that their fitness levels improved their body satisfaction and lowered their social physique anxiety; body satisfaction was particularly important for girls. Thus, early adolescents' psychological well-being may be enhanced through improvements in aerobic functioning.

Weight status and body image perceptions in adolescents: current perspectives.

Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

Biopsychosocial correlates of dietary intent in middle school girls.

Adolescent girls commonly engage in weight management and dietary restriction with the hopes of changing their bodies to more closely approximate social body ideals. The purpose of this study was to examine biopsychosocial factors that predict dietary restraint. Participants (n=774, Mage=12.38) completed measures of dietary intent, pubertal status, sociocultural pressures, body comparison, internalization, body dissatisfaction, social support, and general self-esteem. Height, weight, and cardiorespiratory fitness were objectively measured. Pressures to lose weight and gain muscle mass, internalization of social body ideals, and friend support predicted higher levels of dietary intent; cardiorespiratory fitness predicted lower levels of dietary intent. Girls who experience pressure, adopt social body ideals as their own, and experience social support from friends may be at increased risk for disturbed eating attitudes and behaviors. Fitness may offer a protective effect against psychological and social risk factors. Additional research is needed to establish the causal nature of these relationships and determine effective methods for reducing disordered eating risk among adolescent girls.

Cardiorespiratory Fitness May Help in Protecting Against Depression Among Middle School Adolescents.

PURPOSE: Cross-sectional studies demonstrate a robust association between depression, physical activity, and cardiorespiratory fitness in adolescents, but longitudinal evidence that can better parse the direction of these effects is scarce and conflicting, and no such studies in adolescents have considered the importance of fitness (as opposed to physical activity per se) for preventing depression. Therefore, the present study sought to determine if cardiorespiratory fitness in the first year of middle school (sixth grade) would protect against developing depression a year later (seventh grade), even after controlling for other risk factors (i.e., preexisting depression levels and weight status). METHODS: Participants (N = 437 with 54.9% female) were recruited from six different middle schools during their sixth-grade year and reassessed during the seventh grade. At each assessment, participants completed self-report measures of depression and fitness. Participants were also weighed and were asked to complete a shuttle-run at both points. RESULTS: A cross-lagged panel model indicated that cardiorespiratory fitness in the sixth grade was associated with significantly less depression by the seventh grade in girls, even after controlling for preexisting depression and weight. The effect was in the same direction for boys, but was nonsignificant. In both cases, effects were modest to small. CONCLUSIONS: Cardiorespiratory fitness had a small, but significant protective effect against developing depression in middle school girls, and may have a similar but smaller effect in boys. Promotion of cardiorespiratory fitness can be an important strategy for preventing depression in middle school adolescents, but needs to be coupled with interventions that more directly address symptom treatment.

Losing Weight on Reality TV: A Content Analysis of the Weight Loss Behaviors and Practices Portrayed on The Biggest Loser.

A number of weight loss-related reality television programs chronicle the weight loss experience of obese individuals in a competitive context. Although highly popular, such shows may misrepresent the behavior change necessary to achieve substantial weight loss. A systematic, quantitative content analysis of Seasons 10-13 (n = 66 episodes) of The Biggest Loser was conducted to determine the amount of time and number of instances that diet, physical activity, or other weight management strategies were presented. The average episode was 78.8 ± 15.7 min in length. Approximately 33.3% of an episode, representing 1,121 segments, portrayed behavioral weight management-related content. Within the episode time devoted to weight management content, 85.2% was related to physical activity, 13.5% to diet, and 1.2% to other. Recent seasons of The Biggest Loser suggest that substantial weight loss is achieved primarily through physical activity, with little emphasis on modifying diet and eating behavior. Although physical activity can impart substantial metabolic health benefits, it may be difficult to create enough of an energy deficit to induce significant weight loss in the real world. Future studies should examine the weight loss attitudes and behaviors of obese individuals and health professionals after exposure to reality television shows focused on weight loss.

Psychosocial predictors of drive for muscularity in male collegiate athletes.

The purpose of this study was to examine the simultaneous relation of general and sport-specific pressures about body weight and shape, negative affect, and body satisfaction to drive for muscularity (DM) in male collegiate athletes. Participants were 183 male athletes who were drawn from three NCAA Division I institutions and represented 17 different sports. As hypothesized, after controlling for BMI and sport type, sport-specific pressures, negative affect, and body satisfaction were significant predictors, and accounted for 15-34% of the variance in muscularity-oriented body image and muscularity behaviors; general pressures however were not significantly related. These findings offer insight into the personal and social antecedents of DM in male athletes, and serve as a starting point for future research on DM in this population.

Adolescent sleep disparities: sex and racial/ethnic differences.

OBJECTIVES: During adolescence, significant changes occur in sleep (eg, decreased sleep duration and increased sleep problems). To date, few studies have examined whether self-reported sleep duration differences exist between races/ethnicities in early adolescence (ages 11-14 years). METHODS: This study compared sexes and race/ethnicity groups on self-reported sleep duration in a large (n = 1543; 48.9% boys) racially/ethnically diverse (62.7% White, 23.7% Hispanic/Latino, 10.4% African American, and 3.2% Asian) sample of young adolescents (mean age, 12.31) drawn from local middle schools. RESULTS: A 2-way analysis of variance revealed that there was a trend for a significant sex effect (P = .067, partial χ2 = .002), with boys reporting more sleep than girls and significant race/ethnicity effects (P < .001, partial χ2 = .012), with Hispanic and African American students reporting shorter sleep duration than White and Asian students. The interaction between sex × race/ethnicity was significant (P = .014, partial χ2 = .002), with post hoc tests revealing that Hispanic males demonstrated significantly shorter sleep duration than White and Asian males and African American females demonstrating significantly shorter sleep duration than White females. CONCLUSIONS: Given the literature showing short sleep duration is related to various negative health outcomes and all-cause mortality, more research is needed to determine the factors involved in these disparities. Adolescent sleep disparities: sex and racial/ethnic differences.

Personality and psychological correlates of eating disorder symptoms among male collegiate athletes.

Despite a proliferation of research on disordered eating in female athletes, few studies have included male athletes. The purpose of this study was to determine which of five personality and psychological variables of interest (i.e., perfectionism, self-esteem, optimism, reasons for exercise, and appearance orientation) best predicted eating disorder status (i.e., symptomatic or asymptomatic) in male athletes. Two hundred three male athletes (Mage=20.29, SD=1.64) from three National Collegiate Athletic Association (NCAA) Division I institutions participated. More athletes were asymptomatic (80.8%) than symptomatic (19.2%). None of the variables significantly predicted symptomatic status. These findings contrast the literature on predictors of disordered eating symptomatology among female athletes, and suggest the need for further research to identify other potential predictors of eating disturbance among male athletes.

Relations between sedentary behavior and FITNESSGRAM healthy fitness zone achievement and physical activity.

PURPOSE: To investigate the relations between sedentary behaviors and health-related physical fitness and physical activity in middle school boys and girls. METHODS: Students (n = 1515) in grades 6-8 completed the Youth Risk Behavior Survey sedentary behavior questions, the FITNESSGRAM physical fitness items, and FITNESSGRAM physical activity self-report questions. RESULTS: When students reported ≤ 2 hours per day of sedentary behaviors, their odds of achieving the FITNESSGRAM Healthy Fitness Zone for aerobic capacity, muscular strength and endurance, flexibility, and body composition increased. Similarly, the odds of achieving physical activity guidelines for children increased when students reported ≤ 2 hours per day of sedentary behaviors. CONCLUSIONS: Results illustrate the importance of keeping sedentary behaviors to ≤ 2 hours per day in middle school children, thus increasing the odds that the student will achieve sufficient health-related fitness benefits and be more likely to achieve the national physical activity guidelines.

Relationship of weight-based teasing and adolescents' psychological well-being and physical health.

BACKGROUND: To date, research has focused primarily on psychological correlates of weight-based teasing. In this study, we extended previous work by also examining physical health-related variables (eg, physical self-concept and physical fitness [PF]). METHODS: Participants included 1419 middle school students (637 boys and 782 girls). Of these, 245 (17.3%) reported being teased about being overweight. Participants completed measures of self-esteem, depression, physical self-concept, physical activity (PA) self-efficacy, and self-report physical and sedentary activities. Participants also completed PF testing. RESULTS: After controlling for demographic characteristics, participants who were teased about being overweight had higher scores on depression and lower scores on self-esteem, physical self-concept, PA self-efficacy, and health-related measures of PF in comparison to participants who were not teased. CONCLUSIONS: The results of this study support previous research indicating relationships between teasing and low levels of psychological well-being, physical self-concept, and PA self-efficacy, and establishes one between weight-based teasing and different types of PF. Research is needed to determine the potential causal nature of the relationships between teasing and fitness and evidence-based interventions are needed to reduce weight-based teasing and its potential effects on health and well-being.

Dieting, exercise, and intuitive eating among early adolescents.

Dieting to lose weight, with its focus on restriction of caloric intake, may disrupt intuitive eating processes, though other forms of weight loss, such as exercising, which do not emphasize food may not. In a sample of 669 middle school boys and 708 girls, regardless of sex or exercising, dieting was related to feeling less free to eat what was wanted and to eating more to soothe emotions than to satisfy actual physical hunger. Exercising, independent of dieting, was associated with feeling less permission to eat what was wanted, but also eating to satisfy physical hunger as opposed to coping with emotional distress. Overall, girls were more aware and trusting of their bodily hunger and satiety cues than boys, but when boys were exercising, they scored similarly to girls on this dimension. These findings suggest that different weight loss approaches - dieting vs. exercising - have unique relationships to young adolescents' intuitive eating and these associations tend to be stable across sex. Longitudinal studies now are needed to examine how dieting that begins in childhood or early adolescence might have long-term effects on the progression of intuitive eating.
