  This cross-sectional study analyzed by gender the association between body weight perception and weight control behavior with quality of life (QL) in 563 middle school students (age x. = 13.3, SD = 0.94), from all grades of nine middle schools of South region of Jalisco state realized in 2010. There were 51.9% boys and 19.8% worked. A self-administered questionnaire on line was used (YQOL-R), perceptual module, and five items of body weight adapted from 2009 Middle School YRBS. Statistical analysis included chi squared, Student t test, Spearman correlation, ANOVA and Tamhane�Ls T2. Results: QOL was higher in normal weight perception category than low weight or overweight perception categories; a negative correlation between QOL and weight perception was observed (overweight rs = -.22; low weight rs = -.16); QOL was lower in those who tried to maintain weight in total sample and in girls in relation to those who tried to maintained it. We concluded that weight control behavior is associated with weight perception and both are associated with quality of life. Gender was important to understand the variables studied.

  Este estudio transversal analizo la asociacion de la percepcion del peso corporal y el comportamiento alimentario de control de peso con la calidad de vida (CV) por genero, en 563 estudiantes de secundaria (edad x. = 13.3, DE = 0.94) de todos los grados de nueve secundarias de la region del sur de Jalisco realizado en 2010. Eran 51.9% varones, 19.8% del total trabajaban. Se auto-administro en linea un cuestionario de CV (YQOL-R) modulo perceptual, y cinco items acerca del peso adaptados del 2009 Middle School YRBS. Estadistica: chi cuadrada, t de Student, p de Spearman y ANOVA, T2 de Tamhane. Resultados: CV mas alta para peso percibido cercano al correcto, respecto a bajo peso y sobrepeso; correlacion negativa entre CV y percepcion del peso (sobrepeso rs = -.22; bajo peso rs = -.16); CV mas baja en quienes trataban de mantenerse en su peso en muestra total y en mujeres respecto a las que querian mantenerlo. Concluimos que el comportamiento alimentario esta asociado de manera importante a la percepcion del peso y ambos a la calidad de vida, y el genero es fundamental para comprender las variables estudiadas.
