ABSTRACT El presente estudio analiza la estructura factorial y las propiedades psicométricas de la Eating Self-Efficacy Scale (ESES; Glynn y Ruderman, 1986), un instrumento desarrollado para medir la autoeficacia en relación a la ingesta alimentaria. En el estudio han participado 298 sujetos distribuidos en dos grupos: con normopeso (n= 193) y con exceso de peso (n= 105). Los análisis factoriales exploratorios apoyan la existencia de una estructura bidimensional, con los factores Afecto Negativo y Circunstancias Socialmente Aceptables. El análisis factorial confirmatorio corrobora este modelo de dos factores con una muestra independiente (N= 345). La escala y sus subdimensiones muestran un elevado nivel de consistencia interna. Por último, se han encontrado asociaciones entre las puntuaciones a la ESES y otras variables con las que hipotéticamente estarían relacionadas.

    ABSTRACT: Overweight and obesity in children in Mexico was among the countries with the highest prevalence's in the world. Mexico currently has few innovative and comprehensive experiences to help curb the growth of this serious public health problem. Therefore, the aim of this study is to assess the effectiveness of a nutrition and physical activity strategy, called "Nutrition on the Go" ("nutrición en movimiento") in maintaining the BMI values of school children in the State of Mexico. A two-stage cluster trial was carried out. Sixty schools were selected in the State of Mexico, of which 30 were randomly assigned to the intervention group (IG) and 30 to the control group (CG). A total of 1020 fifth grade school children participated. The intervention strategy aimed to decrease the energy content of school breakfasts and include fruits and vegetables, as well as increase physical activity and the consumption of water during the time spent at school. The strategy was implemented over a 6-month period. The estimated probability (EP) of obesity between baseline and the final stage for the IG decreased 1% (Initial EP = 11.8%, 95%CI 9.0, 15.2, final EP = 10.8, 95%CI 8.4, 13.) For the CG, the probability increased 0.9% (baseline EP = 10.6%; 95%CI 8.1, 13.7; final EP = 11.5, 95%CI 9.0, 14.6). The interaction between the intervention and the stage is the average odd time corrected treatment effect, which is statistically significant (p = 0.01) (OR = 0.68, 95%CI 0.52, 091).This represents the interaction between intervention and stage, which is highly significant (p = 0.01) (OR = 0.68; 95%CI 0.52, 091). In addition, girls had a protective effect on obesity (OR = 0.56; 95%CI 0.39, 0.80). The intervention strategy is effective in maintaining the BMI of school children.

    ABSTRACT: This study examined the factor structure and psychometric properties of the Spanish version of the Weight Efficacy Life-Style Questionnaire (WEL), an instrument developed to measure self-efficacy in relation to food intake. A total of 292 Spanish persons participated, from three groups: clinical group, overweight group, and normal-weight group. The findings showed evidence of three situational factors (Negative Emotions, Social Pressure, and Physical Discomfort). The confirmatory factor analysis corroborated the three-factor model on an independent sample (N = 345). The results show a high degree of internal consistency of the scores of WEL. Significant correlations were found between the WEL scores and other variables that were hypothesized would be related to them. Significant differences on self-efficacy scores were found between some of the groups. The scores of WEL also significantly correlated with the Eating Self-Efficacy Scale scores. Finally, results are discussed and future research directions are suggested.
