Food groups, diet quality and colorectal cancer risk in the Basque Country.

BACKGROUND: The results obtained to date concerning food groups, diet quality and colorectal cancer (CRC) risk vary according to criteria used and the study populations. AIM: To study the relationships between food groups, diet quality and CRC risk, in an adult population of the Basque Country (North of Spain). METHODS: This observational study included 308 patients diagnosed with CRC and 308 age- and sex-matched subjects as controls. During recruitment, dietary, anthropometric, lifestyle, socioeconomic, demographic and health status information was collected. Adherence to the dietary recommendations was evaluated utilizing the Healthy Eating Index for the Spanish Diet and the MedDietScore. Conditional logistic regressions were used to evaluate the associations of food group intakes, diet quality scores, categorized in tertiles, with CRC risk. RESULTS: The adjusted models for potential confounding factors showed a direct association between milk and dairy products consumption, in particular high-fat cheeses [odds ratio (OR) third tertile vs first tertile = 1.87, 95% confidence intervals (CI): 1.11-3.16], and CRC risk. While the consumption of fiber-containing foods, especially whole grains (OR third tertile vs first tertile = 0.62, 95%CI: 0.39-0.98), and fatty fish (OR third tertile vs first tertile = 0.53, 95%CI: 0.27-0.99) was associated with a lower risk for CRC. Moreover, higher MD adherence was associated with a reduced CRC risk in adjusted models (OR third tertile vs first tertile = 0.40, 95%CI: 0.20-0.80). CONCLUSION: Direct associations were found for high-fat cheese, whereas an inverse relation was reported for fiber-containing foods and fatty fish, as well as adherence to a Mediterranean dietary pattern.

Prevalence and magnitude of body weight and image dissatisfaction among women in dietetics majors / Prevalencia y magnitud de la insatisfacción con el peso e imagen corporal en mujeres estudiantes de Dietética

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 (non-random 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.

Algunos autores han sugerido que los estudiantes de Dietética pueden presentar una elevada insatisfacción con el peso corporal. Por este motivo, se llevó a cabo el presente trabajo con el objetivo de analizar la insatisfacción con el peso y la imagen corporal en una muestra de mujeres estudiantes de Dietética. Además, se analizaron predictores de la magnitud de la insatisfacción con el peso corporal. Las participantes fueron 62 voluntarias con normopeso que tenían una media de edad de 21,87±1,89 años (muestra no aleatoria). La evaluación incluyó medidas antropométricas, el test somatomórfico matrix y el eating disorders inventory (EDI-2). Los resultados se analizaron con el programa estadístico SPSS vs. 15.0. Un elevado porcentaje de estudiantes eligieron un peso ideal menor que su peso actual (67,7%) e imágenes corporales con menos grasa corporal y más masa muscular que la que tienen actualmente (56,4%). La magnitud de la insatisfacción con el peso corporal se asoció con la insatisfacción con la grasa corporal y la masa muscular, y con la subescala “insatisfacción corporal” del EDI-2. Por lo que, desde el punto de vista de salud pública, consideramos de interés seguir trabajando en esta línea de investigación con el objetivo de comprender mejor el grado de insatisfacción con el peso corporal en mujeres dietistas, y cómo esa insatisfacción podría afectar a su práctica profesional.
