“…This result can be explained in view of some evidence among females that associated a higher BMI with higher PA levels triggered by their desire to exercise to lose weight (Ingledew and Sullivan, 2002). Additionally, the possible mediating role of BMI in the relationship between PA and GSC, already hypothesized in previous studies (Reddon et al, 2017), was only supported among males, which is in line with Mak et al (2016).…”

“…For the design of the initial model, we considered the theory about the effect of PA on self-concept and the effect of PA on BI. We started from an adaptation of EXSEM (Sonstroem and Morgan, 1989) and some aspects from the variant proposed by Martin-Ginis et al (2012) or the role of BMI on PA and BI (Mak et al, 2016). The possible direct effects among some variables, such as PA and GSC (Sani et al, 2016), were also included.…”

Objective: The aim of this research was to study the mediation of body dissatisfaction, physical self-concept, and body mass index (BMI) on the relationship between physical activity and self-concept in adolescents. Materials and Methods: A sample of 652 Spanish students between 12 and 17 years participated in a cross-sectional study. Physical self-concept and general self-concept were assessed with the Physical Self-Concept Questionnaire (CAF), body dissatisfaction with the Body Shape Questionnaire (BSQ), and physical activity was estimated with the International Physical Activity Questionnaire (IPAQ-SF). BMI was utilized as a measurement of body composition. Structural equation modeling was used to assess the results. Results: The resulting models showed good fit indexes. Final model for all participants explained the 17% of the variance of body dissatisfaction, 57% of physical self-concept, and 60% of general self-concept. Physical activity had a positive and indirect effect on self-concept ( β = 0.29, p < 0.01) and direct effects on body dissatisfaction ( β = −0.26, p < 0.01) and physical self-concept ( β = 0.20, p < 0.01). BMI had a direct effect on body dissatisfaction ( β = 0.31, p < 0.01) and on physical self-concept ( β = −0.10, p < 0.01) and an indirect effect on general self-concept ( β = −0.24, p < 0.01). However, it was only associated with physical activity in males, playing a mediating role between physical activity and body dissatisfaction. Conclusion: Physical activity can help individuals to achieve a positive self-concept and promote psychological well-being in adolescents through the improvement of physical perceptions and body satisfaction. The importance of BMI, body dissatisfaction, and physical self-concept on the configuration of the self-concept is also emphasized. Educational policymakers and Physical Education teachers should implement strategies to promote physical activity in the schools and provide a Quality Physical Education programs to increase physical activity during adolescence.

“…Male and female Brazilian adolescents scored higher (57.2 and 53.1, respectively) on total body esteem than in a study that examined 905 Hong Kong adolescents using the same scale (boys -42.33; girls -40.05). 8,10 Consistent with similar studies, 4,10,11 in the studied group, boys tended to have higher body esteem than girls, and this relationship differed according to age group.…”

“…Moreover, other studies that applied the same questionnaire observed consistent findings, especially emphasizing the relation between body esteem and health. 8,10,11 Furthermore, sex and age have been considered factors that strongly influence body esteem, especially among adolescents. Mendelson et al 4 evaluated 571 male and 763 female adolescents and young adults (between 12 and 25 years old) from Canada and observed that girls scored less than boys for total body esteem.…”

Objective: To investigate the association between weight status and anthropometric indicators of adiposity with body esteem.Methods: Cross-sectional study including 305 adolescents from a public school in Rio de Janeiro, Brazil. Data were collected by a selfadministered questionnaire and anthropometric measurements.The Body-Esteem Scale for Adolescents and Adults was used to evaluate total body esteem and the "appearance", "weight", and "attribution" domains. Body mass index (weight/stature 2 ) was applied to assess weight status and waist circumference, the central body adiposity. The association between indicators of adiposity and body esteem was assessed using Student's t-test or Mann-Whitney's test and linear regression models, stratified by sex and age group. Results: Overweight/obesity was observed in 46% of younger adolescents (10 to 13 year-old girls, 10 to 14 year-old boys), 38% of older boys (15 to 18 year old), and 16% of older girls (14 to 18 year old). For both boys and girls in the younger age group, body mass index and waist circumference (as continuous variables) were inversely associated with total body esteem and weight domain. Overweight/obesity was associated with the appearance body esteem domain only among younger male adolescents; no association was found between either the body mass index or waist circumference and the attribution domain. Conclusions: Indicators of adiposity were associated with low body esteem. These findings underscore the fact that considering adolescents' feelings concerning their body and appearance is important to promote a healthy control of weight. Objetivo: Investigar a associação entre a condição de peso e os indicadores antropométricos de adiposidade com a estima corporal. Métodos: Estudo transversal com 305 adolescentes de uma escola pública do Rio de Janeiro, Brasil. Os dados foram coletados utilizando um questionário autoaplicado e por meio de medidas antropométricas. A Escala de Estima Corporal para Adolescentes e Adultos foi utilizada para avaliar a estima corporal total e os domínios "aparência", "peso" e "atribuição". O índice de massa corporal (peso/estatura 2 ) foi utilizado para avaliar a condição do peso e circunferência da cintura, a adiposidade central. A associação entre indicadores de adiposidade e estima corporal foi avaliada por meio dos testes t de Student ou Mann-Whitney e por modelos de regressão linear, estratificados por sexo e faixa etária. Resultados: Sobrepeso/obesidade foi observado em 46% dos adolescentes mais jovens (meninas de 10 a 13 anos, meninos de 10 a 14 anos), em 38% dos meninos de 15 a 18 anos e em 16% das meninas de 14 a 18 anos. Na faixa etária mais jovem, o índice de massa corporal e a circunferência da cintura (como variáveis contínuas) foram inversamente associados à estima corporal total e ao domínio peso, tanto em meninos quanto em meninas. O sobrepeso/obesidade associou-se ao domínio corporal 'aparência' apenas entre os meninos mais jovens. Nenhuma associação foi encontrada entre índice de massa corporal e a circunferê...

“…A difference should also be highlighted in the role taken on by body image in the model put forward by Fernández-Bustos et al (9) and ours. In this respect, they provided body image with a mediating role between BMI and physical activity (50), whereas our study showed body image to be an independent construct which, alongside anthropometric values and variables associated with physical ability, predict self-concept. Therefore, it should be noted that anthropometric variables such as BMI are associated with body dissatisfaction in both men and women (10).…”

The aim was to analyze the extent to which anthropometric values, in line with body image and physical ability, predict physical self-concept, and the latter, in turn, predicts the practice and intention to pursue physical activity. A total of 302 participants, 150 males and 152 females were recruited from different primary schools in Extremadura (Spain). The age of the participants ranges from 10 to 13 years old (M = 11.74; SD = 0.86). The indirect effects of the model showed significant relationship between physical condition (p = 0.001) and PA levels, according to the perception of self-concept [β = 0.231, 95% BcCI = (0.055, 0.212)]. However, anthropometric variables proved not to be related to any significant extent (p < 0.05). The second level covered the indirect effects between the intention to be physically active and self-concept, which showed a significant relationship between the perception of self-concept (p = 0.000) and the intention to be physically active. Last, the third level showed significant relationships between physical condition (p = 0.001) and the intention to pursue physical activity. The present investigation concluded that physical condition, anthropometric variables, and body image predict the perception of physical self-concept in adolescents. Finally, this article highlights the importance of body image perception, anthropometric values, and physical condition in the intention of being physically active. In addition, it highlights the mediating role of physical self-concept to develop physical activity.
