ABSTRACT
Obesity and eating disorders are currently two significant health problems in Mexico. The aim of this study was to examine the effects of an integrated prevention program on university students through an exploratory controlled study that targeted specific predisposing factors of disordered eating and obesity related to healthy eating, physical activity, body image satisfaction and perceived pressure to be thin. A total of 388 university students participated (264 females and 124 males) and were assigned either to an intervention condition or one of the two control conditions (study skills vs. nonintervention); each comprised of a total of eight workshops lasting 90 min. The program did not have any effect on the male students. In contrast, there was an interaction effect for time and group in thin-ideal internalization (η2 = 0.04) and in disordered eating attitudes/behaviours (η2 = 0.03); both showed improvements over time only among the female sample. Though, the effect size was insignificant, which means that the effectiveness of this integrated prevention program was limited. Integrated prevention approaches to eating and weight-related problems are still nascent in Mexico, and further research in this field is warranted so as to fine tune future prevention programs.

The study of the factors that regulate high energy food intake is especially relevant nowadays due to the high prevalence of overweight and obesity. Food intake regulation can be divided in two basic processes, namely satiation and satiety. Satiation is the process that determines the moment in which feeding stops and regulates the amount of ingested food during a single meal. Satiety is the interval between meals and regulates the time elapsed between two meals. The longer the interval, the lower energy intake. Each of these processes are regulated by different factors, which are here reviewed.

El objetivo de este artículo es presentar una clasificación para el estudio de las conductas alimentarias y el estado nutricional en el proceso de enfermedad del cáncer. Las conductas alimentarias son un factor que interviene en la aparición, progresión y tratamiento del cáncer, además de comprometer el estado nutricional de los individuos. La relación entre nutrición y cáncer es bidireccional: por un lado, una alimentación inadecuada puede aumentar la incidencia de determinados cánceres, así como alterar el estado nutricional de los pacientes que ya presentan la enfermedad, y por otro lado, el propio cáncer y sus tratamientos pueden inducir la aparición de problemas nutricionales que se presentan en un 40-80% de los pacientes en el curso de la enfermedad. Por esta relación se hace evidente la dependencia que existe entre conducta alimentaria y cáncer. Las conductas alimentarias pueden estudiarse en tres etapas: conducta alimentaria antes del cáncer, conducta alimentaria durante el cáncer y conducta alimentaria después de los tratamientos. Por tal motivo, la investigación acerca del estado nutricional de los pacientes y las conductas alimentarias que se manifiestan en este lapso es fundamental para conocer y evitar el aumento de la morbilidad y mortalidad de las personas por cáncer.
