Objective: To evaluate the effects of a universal prevention programme for disordered eating behaviours (DEB) and sedentary lifestyle among Mexican young people. Design: Non-experimental single group field study with repeated measures (pre-test, post-test and at 6-month follow-up). Setting: Public high school in Hidalgo, Mexico. Methods: In all, 214 young women and 154 young men aged 15–18 years with a mean age of 16.4 participated in the study. For both young women and men, data were collected using the Brief Questionnaire for Disordered Eating Behaviours (DEB) and the short form of the International Physical Activity Questionnaire. Among young men, additional data were collected using the Drive for Muscularity Scale (DMS). Intervention: Five activity-based sessions. In the first four sessions, the following topics were addressed: thinness culture, myths and realities of dieting and supplements, healthy eating behaviours and healthy menus. At the end of each session, students engaged in an enjoyable physical activity hour. In the fifth session, participants were divided into three parallel workshop groups focusing on: thinness culture, healthy menus, and physical activity. The programme incorporated a variety of dissonance-based interventions using interactive psychoeducational strategies. Results: After 6 months, repeated-measures analyses of variance (ANOVAs) revealed a significant reduction in the mean DEB scores in young women. In young men, DEB and DMS mean scores decreased but not significantly. Physical activity frequency and duration showed a significant increase in the total sample over time. Conclusions: Overall, implementation of the programme had positive effects on young people and important differences were found between the sexes.

The objective of this study was to determine the relationship between the body mass index (BMI) and the body image of indigenous women from Hidalgo, Mexico. Body dissatisfaction/satisfaction was evaluated in 167 adult women (M age = 34.45, SD = 6.76) based on BMI and on the partial markup technique of image. The 83% of women assessed had some degree of body dissatisfaction specially related to the desire of thinness (51%) than with the desire of being robust (32%). Normal weight (21%) and low weight (20%) women were those who were more satisfied with their body image; on the contrary, women with obesity (57%) were the less satisfied. However a significant association among BMI and body satisfaction/dissatisfaction was not identified. One of the main contributions of this study was to analyze the correspondence between two little studied variables in indigenous adult women: BMI and body image. These findings strength the need to keep studying this kind of population as well as the development of preventive and promoting health programs aimed to indigenous groups.

En mujeres se ha reportado que a mayor índice de masa corporal (IMC), mayor interiorización del ideal estético de la delgadez (IIED), y mayor seguimiento de conductas alimentarias de riesgo (CAR). El objetivo de esta investigación consistió en determinar la presencia de CAR y de IIED en mujeres adolescentes de Hidalgo, México y su asociación tanto entre ellas como con el IMC, el porcentaje de grasa corporal (PGC), los tiempos de comida (TC) y la actividad física (AF). El estudio fue de tipo transversal con un diseño no experimental descriptivo y de asociación en una muestra no probabilística de 220 mujeres de preparatoria, de entre 14 a 18 años de edad (Medad = 15.9 ± .99), quienes respondieron una batería de cuestionarios validados. Para obtener el IMC, cada participante fue pesada y medida, mientras que el PGC se obtuvo por bioimpedancia eléctrica. Los resultados arrojaron que 17.3 % de la muestra presentó riesgo moderado y 15.5 % alto de CAR; mientras que 23.2 % registró riesgo de IIED. Se encontró que el IMC aumenta significativamente 2.7 veces el riesgo de IIED y de CAR 2.5 veces; la IIED incrementa 11.8 veces el riesgo de CAR (Odd Ratio; . < .05). Se concluye que, en la muestra de estudio, las CAR y la IIED están presentes; que a mayor IIED mayor riesgo de estas y que un exceso de peso corporal, basado en el IMC, aumenta el riesgo tanto de CAR como de IIED. Es necesario que los programas de prevención para mujeres adolescentes consideren lo anterior de manera conjunta para garantizar su éxito.
