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: This paper presents the development and validation of a weight control selfefficacy inventory measuring self-efficacy perceptions in three areas of weight control –feeding style, influence of external stimuli on over-eating behaviors and physical activity patterns. Following an exhaustive literature review, an opinion interview and consultation with 4 experts in the area, 120 items were built. The statistical item analysis in a sample of 193 students allowed us to sort out 37 items out of the original pool. Then, reliability and validity analyses were performed in a sample of 439 students. Factor analysis resulted in 3 factors explaining 44.083% of the total variance. Satisfactory internal consistencies were found for each factor (.88, .91 and .88 respectively). Results are discussed and directions for future research are suggested.

    ABSTRACT: Achieving a preventive attitude is the first step in eliminating cancer risk behaviours. This cross-sectional study evaluated the attitude towards the European Code against Cancer, in 3,031 relatives of cancer patients. The study looked for keys to improve attitude by means of educational interventions. Attitude was evaluated using a questionnaire with 63 items and a Likert's scale. Measured from -2 to +2 , the mean score was 0.905 [0.894 - 0.971]. Five per cent had a mean score under 0.38 and another 5% over 1.46. A multivariate analysis found that age, sex and level of education were significantly associated with attitude: young men with a low cultural level were those with the lowest preventive attitude. The family history of cancer was not associated with attitude. Educational interventions should modify the perceived advantages of smoking and drinking, and the disadvantages related to preventive diet and sun and workplace protection.

    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.
