ABSTRACT
La presente investigación es de tipo cuantitativa con diseño no experimental, transversal y retrospectiva. Se realiza en preadolescentes de educación básica de nivel primaria del norte de México; la muestra estuvo constituida por 992 sujetos, 500 niñas y 492 niños. Rescata la percepción corporal: imagen real, ideal, social, futura, inconformidad corporal, expectativa corporal, distorsión corporal social e idealización corporal, en relación a las variables de género y nivel socioeconómico; para lo que se utiliza como instrumento de medición la escala Body Image Assessment (BIAS), versión informatizada de la versión original. Los resultados obtenidos muestran, aunque no de manera contundente, en relación al género, que las niñas son más vulnerables a problemáticas relacionadas con la imagen corporal, así como los preadolescentes, niños y niñas, del nivel socioeconómico alto.
The present investigation is of a quantitative type with a non-experimental, transversal and retrospective design. The sample consisted of 992 subjects, 500 girls and 492 boys. This is done in primary school with pre-teens in northern Mexico. It rescues the corporal perception: real, ideal, social, future image, corporal nonconformity, corporal expectation, social corporal distortion and corporal idealization, in relation to the variables of gender and socioeconomic level; for what is used as a measuring instrument the computerized version of the original Body Image Assessment (BIAS). The results obtained show, although not overwhelmingly, in relation to gender, that girls are more vulnerable to problems related to body image, as well as preadolescents, boys and girls, of a high socioeconomic level.

OBJECTIVE: Physicians who know about physical activity guidelines (PAG) and those who adhere to the PAG themselves may have a greater tendency to recommend physical activity (PA) to their patients. This study was aimed at evaluating the level of PA in a group of medical residents from Puerto Rico and to assess their knowledge regarding the PAG for adults. METHODS: A total of 104 medical residents from Puerto Rico completed a selfadministered questionnaire designed to obtain standardized estimates of their PA and to determine their level of knowledge regarding the PAG. RESULTS: Results: Most of the medical residents (66.3%) declared that they did not have any knowledge of the existence of the PAG and that their residency programs had not provided any educational activities about the PAG (96.2%). The level of inactivity among medical residents was high; 41.35% reported not engaging in any PA during their leisure time. CONCLUSION: Most of the medical residents in this group from Puerto Rico did not know about the PAG and many of them did not engage in PA. As a means of improving patient care, medical residents from Puerto Rico might benefit if their programs implemented educational activities aimed at increasing knowledge of both PA and the PAG.
