          Abstract

          OBJECTIVE: To construct a scale for assessing the quality of mealtime habits in a sample of urban Mexican adults, computing the contribution of a set of advisable and unadvisable mealtime habits. MATERIAL AND METHODS: We performed an exploratory factor analysis among 7 472 adults participating in the baseline assessment of the Health Workers Cohort Study, to assess the mealtime habits quality. Likelihood ratio test for difference of two probabilities and test for the difference of two means were used to identify differences between low and high categories of the Mealtime Habits Quality Scale (MHQS) across variables of interest. RESULTS: Participants with the top quality of mealtime habits showed lower rates of overweight, obesity, abdominal obesity, and elevated body fat. They were also more adherent to a prudent dietary pattern than a western dietary pattern, and consumed more fruits and vegetables. CONCLUSIONS: Anthropometric and dietary variables differed across MHQS categories. However, further validation of the scale, and assessment of their ability to predict weight gain or related diseases are needed, using prospective and intervention studies.

          OBJETIVO: Construir una escala para evaluar la calidad de los hábitos al comer, calculando la contribución de un grupo de hábitos recomendables y no recomendables, en población adulta urbana de México. MATERIAL Y MÉTODOS: Realizamos un análisis exploratorio de factores en 7 472 adultos participantes en el Estudio de Cohorte de Trabajadores de la Salud para evaluar la calidad de los hábitos al comer. Para identificar diferencias entre la baja y alta calidad de los hábitos al comer a través de las variables de interés, utilizamos la prueba de razón de probabilidades a fin de evaluar la diferencia entre dos proporciones y la prueba de comparación de medias. RESULTADOS: Los participantes clasificados en la categoría de alta calidad de los hábitos al comer presentaron prevalencias más bajas de sobrepeso, obesidad, obesidad abdominal y porcentaje de grasa corporal elevado. Además, mostraron mayor adherencia al patrón dietario prudente que al patrón dietario occidental, así como mayor consumo de frutas y verduras. CONCLUSIONES: Las variables antropométricas y de dieta muestran diferencias a través de las categorías de la escala de la calidad de hábitos al comer. Sin embargo, será necesario validar la escala y evaluar su capacidad para predecir ganancia de peso o enfermedades relacionadas, mediante estudios prospectivos o de intervención.

          Who succeeds in maintaining weight loss? A conceptual review of factors associated with weight loss maintenance and weight regain.

          Weight loss is difficult to achieve and maintaining the weight loss is an even greater challenge. The identification of factors associated with weight loss maintenance can enhance our understanding for the behaviours and prerequisites that are crucial in sustaining a lowered body weight. In this paper we have reviewed the literature on factors associated with weight loss maintenance and weight regain. We have used a definition of weight maintenance implying intentional weight loss that has subsequently been maintained for at least 6 months. According to our review, successful weight maintenance is associated with more initial weight loss, reaching a self-determined goal weight, having a physically active lifestyle, a regular meal rhythm including breakfast and healthier eating, control of over-eating and self-monitoring of behaviours. Weight maintenance is further associated with an internal motivation to lose weight, social support, better coping strategies and ability to handle life stress, self-efficacy, autonomy, assuming responsibility in life, and overall more psychological strength and stability. Factors that may pose a risk for weight regain include a history of weight cycling, disinhibited eating, binge eating, more hunger, eating in response to negative emotions and stress, and more passive reactions to problems.

            International ethical guidelines for biomedical research involving human subjects.

            (2002)
            The CIOMS guidelines have been developed and revised with the problems of conducting medical research in less developed countries particularly in mind. The proposed guidelines were first published in 1982, revised in 1993, and have now been published in a third version after a revision process lasting three years. Last month the Bulletin published just one guideline and accompanying commentary. There now follow all the guidelines, without commentary, but with an appendix detailing what should be in a protocol.
