-A high prevalence of body image dissatisfaction has been observed among adolescents over the last decades. The aim of this study was to evaluate the association between body image dissatisfaction and demographic factors in adolescents. The sample consisted of 405 boys and girls (247 from an urban area and 158 from a rural area) aged 14 to 17 years enrolled in public schools of a small-sized municipality. The demographic variables analyzed were gender (male, female), age (14-15 years, 16-17 years), and area of residence (urban, rural). The perception of body image was evaluated using a figure rating scale. The prevalence of body image dissatisfaction was 56.5%. Both girls (26.5%) and boys (39.5%) wished to have a larger body silhouette. An association was observed between body image dissatisfaction and gender, with boys showing a 1.24 times higher chance (95%CI: 1.05-1.47) of body image dissatisfaction than girls. The prevalence of body image dissatisfaction is high even among adolescents from small-sized municipalities. Body image dissatisfaction is more prevalent among boys. Healthcare workers and teachers should be aware of the importance to encourage youngster to better understand themselves and their body and to reflect about current body images.

O presente estudo teve por objetivo verificar a associação entre a insatisfação com a imagem corporal e os fatores demográficos em adolescentes. A amostra foi composta por 405 escolares (247 domiciliados na área urbana e 158 na rural), de ambos os sexos, de 14 a 17 anos, do ensino público de um município de pequeno porte. As variáveis demográficas analisadas foram sexo
RESUMOO objetivo do presente estudo foi verificar a prevalência da percepção com a imagem corporal (IC) e identificar a associação com fatores sociodemográficos, estado nutricional e maturação sexual em escolares do sexo masculino (7 a 17 anos) do município de Cascavel, PR, Brasil. Foram avaliados 1.521 escolares e analisadas as variáveis idade, série, nível econômico, IMC, maturação sexual e a percepção da imagem corporal. Utilizou-se o teste qui-quadrado e a regressão logística multinomial. A prevalência de insatisfação com a IC foi de 74,7%, e os escolares que desejam diminuir a silhueta possuem de sete a 13 anos (RC=2,81; IC95%=1,48-5,31) e apresentam estado nutricional normal (RC=0,14; IC95%=0,20). Aqueles que desejam ter uma silhueta maior têm entre sete e dez anos (RC=1,86; IC95%=1,15-3,02), cursam o Ensino Fundamental (RC=0,50; IC95%=0,30-0,85) e possuem estado nutricional normal (RC=2,17; IC95%=1,45-3,27). Conclui-se que a insatisfação com a imagem corporal associou-se com a idade, série e estado nutricional. INTRODUÇÃOA imagem corporal pode ser definida como uma construção multidimensional (THOMPSON, 1990), a qual representa como as pessoas pensam, sentem e se comportam a respeito da sua forma física (MUTH; CASH, 1997). A partir disso, surgem dois aspectos específicos da imagem corporal: a exatidão da estimativa do tamanho do corpo e os sentimentos gerados em relação às suas porções e a ele como um todo -insatisfação corporal ou desvalorização da forma física (CORDÁS; CASTILHO, 1994).A sociedade vem demonstrando uma preocupação excessiva com os padrões de beleza, os quais têm exigido perfis antropométricos cada vez mais magros para o sexo feminino e fortes para o sexo masculino (PEREIRA et al., 2009). A obsessão pela perfeição da beleza física converte-se em doenças emocionais, seguida por ansiedade, depressão, fobias, atitudes compulsivas e repetitivas, conduzindo a pessoa a desenvolver o transtorno dismórfico corporal, que tem como sintomas o desejo de uma imagem corporal perfeita e a distorção da real imagem diante do espelho (FERREIRA; CASTRO; GOMES, 2005). A busca pelo corpo considerado ideal faz com que a sociedade apresente alterações na representação da imagem corporal, inclusive em crianças e adolescentes, visto que estudos
Objective To identify biological and psychosocial factors associated with dropout in a multidisciplinary behavioral intervention in obese adolescents.Methods A total of 183 adolescents (15.4±1.6 years), pubertal (Tanner stage 3 or 4) and obese (34.7±4.0kg/m2), were enrolled in a 12-week behavioral intervention, which included clinical consultations (monthly), nutritional and psychological counseling (once a week), and supervised aerobic training (three times/week). The studied variables were weight, height, body mass index, body composition (skinfold), cardiorespiratory fitness (direct gas analysis), blood lipids and self-reported symptoms of eating disorders (bulimia, anorexia and binge eating), anxiety, depression, body image dissatisfaction and quality of life. Statistical analysis included binary logistic regression and independent t-tests.Results Of the adolescents, 73.7% adhered to the program. The greatest chance for dropout was observed among adolescents older than 15 years (odds ratio of 0.40; 95%CI: 0.15-0.98), with more anorexia symptoms (odds ratio of 0.35; 95%CI: 0.14-0.86) and hypercholesterolemia (odds ratio of 0.40; 95%CI: 0.16-0.91) at baseline.Conclusion Older adolescents, with more symptoms of eating disorders and total cholesterol have less chance to adhere to multidisciplinary treatments.
The aim of this study was to identify the morphological configuration of youth athletes from professional soccer clubs and to verify their differences according to the tactical position on the field. Overall, 67 male players aged 15 to 17 years were evaluated. The examined anthropometric measurements included body mass, body height, skinfolds (triceps, subscapular, supraspinal and medial calf), girths (flexed and tensed arm and calf) and breadths (humerus and femur). For statistical purposes, analysis of variance and post hoc Bonferroni and Kruskal-Wallis tests were used. We concluded that goalkeepers were heavier and taller than center backs (p = 0.015 and p = 0.001), midfielders (p = 0.005 and p <0.001) and center forward players (p = 0.024 and p <0.001). The average somatotype for defense, forward and goalkeeper positions was a balanced mesomorph. Midfield players showed ectomorphic-mesomorph characteristics. It was concluded that goalkeepers were characterized as being taller and heavier and that somatotype features of athletes were similar between positions, except for midfield players.
Both high and low-intensity training improved biomarkers related to NAFLD. Thus, high-intensity training can be a safe and effective alternative to prevent and treat NAFLD in adolescents with obesity.
