A short training program improves the accuracy of portion-size estimates in future dietitians

[EN] The objective of this study was to determine whether a short training program, using real foods, would decreased their portion-size estimation errors after training. 90 student volunteers (20.18±0.44 y old) of the University of the Basque Country (Spain) were trained in observational techniques and tested in food-weight estimation during and after a 3-hour training period. The program included 57 commonly consumed foods that represent a variety of forms (125 different shapes). Estimates of food weight were compared with actual weights. Effectiveness of training was determined by examining change in the absolute percentage error for all observers and over all foods over time. Data were analyzed using SPSS vs. 13.0. The portion-size errors decreased after training for most of the foods. Additionally, the accuracy of their estimates clearly varies by food group and forms. Amorphous was the food type estimated least accurately both before and after training. Our findings suggest that future dietitians can be trained to estimate quantities by direct observation across a wide range of foods. However this training may have been too brief for participants to fully assimilate the application.

Cooperative learning strategies to teach nutrition to geriatric nursing staff

[EN] The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks. The assessment instruments included two pretest and two posttest questionnaires with questions selected in multiplechoice format. The first questionnaire was about general knowledge of applied nutrition (0-88 point scale) and the second one on geriatric nutrition knowledge (0-18 point scale). Data were analyzed using SPSS vs. 11.0. The outcomes indicated a significant increase in general nutrition knowledge (difference between the pre- and posttest mean score: 14.5±10.1; P<0.001) and in geriatric nutrition knowledge for all participants (difference between the pre- and post-test mean score: 4.6±4.6; P<0.001). So the results indicated that cooperative learning strategies could improve the nutrition knowledge of nursing staff. Additionally, the results of this study provide direction to continuing nutrition education program planners regarding appropriate content and methodology for programs.

Prevalence and magnitude of body weight and image dissatisfaction among women in dietetics majors

[EN] Some authors have suggested that body weight dissatisfaction may be high in students majoring in dietetics. Therefore, this study was conducted to examine the extent of body weight and image dissatisfaction in a sample of women in dietetics major. Additionally, predictors of magnitude of body weight dissatisfaction were analyzed. Participants were 62 volunteers with normalweight whose mean age was 21.87±1.89 years old (nonrandom sample). The assessment instruments included anthropometric measurements, a somatomorphic matrix test and an eating disorders inventory (EDI-2). Data were analyzed using SPSS vs. 15.0. A larger proportion of students chose an ideal body weight lower than actual weight (67.7%) and body image with less body fat and more muscle mass than actual values (56.4%). The magnitude of body weight dissatisfaction was associated with muscle mass and body fat dissatisfaction, and with the subscale of EDI-2 “body dissatisfaction”. So, from a public health standpoint, we consider important to continue working in this line of research with the aim of better understanding the extent of body weight dissatisfaction in women dietitians, and how this dissatisfaction could interfere with their professional practice.

La alimentación de personas con discapacidades: cumplimiento de las recomendaciones para la ingesta de alimentos y nutrientes

[ES] Las personas con discapacidades son un grupo heterogéneo de población, con una amplia variedad en factores que afectan a sus hábitos alimentarios y a su estado nutricional. Los resultados del presente estudio ponen en evidencia que la alimentación que reciben los pacientes estudiados no cumple las recomendaciones nutricionales establecidas por organismos nacionales e internacionales.

Sobrepeso, obesidad y bajo peso en niños tratados por el Servicio de Urgencias de Pediatría.

[ES] En el presente trabajo se estudiaron de forma transversal 235 niños con edades comprendidas entre los 2 y 14,9 años. El 6% de la muestra total presentó bajo peso, y el 17% sobrepeso u obesidad. Por lo que concluimos que los servicios de pediatría deberían tener un papel activo en el control y prevención de las alteraciones del estado nutricional.

Imagen corporal en estudiantes universitarios: comportamientos dietéticos y actitudes nutricionales

[ES] En el presente estudio se evalúa la relación entre el estado nutricional, las actitudes y comportamientos dietéticos, y la percepción de la imagen corporal en universitarios. Se registraron más casos de sobrepeso en hombres que en mujeres. Sin embargo, la tendencia a “hacer dietas” fue mayor en las mujeres, lo que podría deberse a la presión social por mantener una imagen estilizada.

Imagen y composición corporal en hombres jóvenes

[ES] El objetivo de este estudio fue analizar la percepción de la imagen corporal y comparar los resultados con las medidas reales en un grupo de hombres universitarios. Los resultados mostraron que desean tener un cuerpo más musculoso que el cuerpo que tienen y que el que creen tener. Además, piensan que las mujeres prefieren hombres con cuerpos musculosos.
