Imagen corporal en adolescentes lituanos de 11 a 19 años. Diferencias según actividad física e IMC

espanolSe estudio la imagen corporal y las diferencias en la misma segun actividad fisica e IMC, en 2942 adolescentes lituanos (1405 chicos y 1537 chicas), de 11 a 19 anos. La imagen corporal se midio mediante el cuestionario HBSC, la actividad fisica mediante el cuestionario PACE y el IMC con la formula peso/altura2, clasificando a la poblacion en Sobrepeso/Obesidad segun el IOTF. Las chicas se veian mas gordas que los chicos (t 2935.50= 11.37; p=0.000; d=0.420). Los sujetos que realizaban menos actividad fisica (t 2012.21= 2.57; p=0.010; d=0.115) y aquellos con sobrepeso/obesidad (t 392.04= 14.86; p=0.000; d=1.501) tuvieron peor imagen corporal. Se recomienda implementar programas de actividad fisica y programas psicologicos para mejorar la imagen corporal y la composicion corporal de los adolescentes lituanos, prestando especial atencion a las chicas, a aquellos que realizan menos actividad fisica y a aquellos con sobrepeso/obesidad. EnglishThis paper studied the body image and its differences by physical activity and Body Mass Index (BMI), in a sample of 2942 Lithuanian adolescents (1405 males and 1537 females), aged between 11 and 19. Body image was measured with the questionnaire HBSC, physical activity with questionnaire PACE, and BMI through the formula height/weight2, classifying the adolescents according to the IOTF. The results indicated that girls saw themselves fatter than boys (t 2935.50= 11.37; p=0.000; d=0.420). The adolescents that performed less physical activity (t 2012.21= 2.57; p=0.010; d=0.115) and those with excess weight/obesity (t 392.04= 14.86; p=0.000; d=1.501) had worse body image. It is recommendable to implement physical activity programs and psychological programs to improve the body image and the body composition of Lithuanian adolescents, paying special attention to girls, those who do less physical activity and those who are overweight/obese.
