- Hábitos alimentarios y actitudes hacia el cambio en alumnos y trabajadores universitarios españoles(Sociedad Española de Nutrición Parenteral y Enteral, 2013) Sanchez-Tainta, A. (Ana); Zazpe, I. (Itziar); Rodriguez-Mourille, A. (Ana); Santiago, S. (Susana); Marques, M. (María); Beunza, J.J. (Juan José); Fernandez-Montero, A. (Alejandro)Introducción: El entorno educativo y laboral ha adquirido protagonismo como ámbito prometedor para llevar a cabo intervenciones nutricionales en población adulta. Objetivos: El objetivo de este trabajo es evaluar los hábitos alimentarios y actitudes hacia el cambio en trabajadores y alumnos universitarios con distinto perfil académico. Métodos: Estudio epidemiológico descriptivo de tipo transversal en población universitaria española de 1429 sujetos. Se analizaron los hábitos alimentarios y las actitudes hacia el cambio de hábitos. Resultados: La edad media de los trabajadores fue de 37 años y en los estudiantes de 23 años. En ambos grupos el fraccionamiento de la ingesta más frecuente fue de cuatro tomas al día. En los alumnos se observó menor frecuencia de consumo de verdura, vino, pescado y frutos secos y mayor de bebidas carbonatadas, repostería comercial, fast-food y carnes rojas. Por otro lado, en general los hábitos alimentarios de los estudiantes de ciencias fueron más saludables que los de letras. Aunque no se observaron diferencias significativas en las actitudes hacia el cambio entre estudiantes y trabajadores, el 32 % de los empleados y el 39 % de los estudiantes afirmaron estar planteándose seriamente cambiar sus costumbres. Conclusiones: el patrón alimentario fue más saludable entre los trabajadores que entre los alumnos, especialmente en aquellos que cursan grados de letras, que constituyen el grupo más vulnerable desde el punto de vista nutricional. Además, aproximadamente un tercio de los trabajadores y alumnos se planteaba modificar sus hábitos.
- Macronutrient quality index and cardiovascular disease risk in the Seguimiento Universidad de Navarra (SUN) cohort(2022) Martinez-Gonzalez, M.A. (Miguel Ángel); Zazpe, I. (Itziar); Vanegas, P. (Paola); Santiago, S. (Susana); Fernández-Lázaro, C.I. (César I.); De-la-O-Pascual, V. (Víctor)Purpose To assess the association between a multi-dimensional Macronutrient Quality Index (MQI) and the risk of cardiovascular disease (CVD) in a Mediterranean cohort. Methods Prospective analyses among 18,418 participants (mean age 36 years, 60.8% women) of the Seguimiento Universidad de Navarra (SUN) cohort. Dietary intake information was obtained through a validated semi-quantitative food-frequency questionnaire (FFQ). The MQI (expressing high-quality macronutrient intake) was calculated based on three previously reported quality indices: the Carbohydrate Quality Index (CQI), the Fat Quality Index (FQI), and the Healthy Plate Protein source Quality Index (HPPQI). Adherence to the Mediterranean diet (MedDiet) and Provegetarian Diet was evaluated using the Trichopoulou index and the score proposed by Martinez-Gonzalez, respectively. CVD was defined as new-onset stroke, myocardial infarction, or CVD death. Results After a median follow-up time of 14 years (211,744 person-years), 171 cases of CVD were identified. A significant inverse association was found between the MQI and CVD risk with multivariable-adjusted HR for the highest vs. the lowest quartile of 0.60 (95% IC, 0.38-0.96; P-trend = 0.024). Conclusion In this Mediterranean cohort, we found a significant inverse relationship between a multidimensional MQI (expressing high-quality macronutrient intake) and a lower risk of CVD.
- Association of dairy consumption with respiratory infections. Myth or reality?(Asociación Española de Pediatría de Atención Primaria, 2018) Moreno-Galarraga, L. (Laura); Martin-Calvo, N. (Nerea); García-Blanco, L. (Lorena); Zazpe, I. (Itziar); Alvarez-Zallo, N. (Noelia); Peñafiel-Freire, D.M. (Diego Mauricio)Introducción: la leche y los derivados lácteos son alimentos importantes para el desarrollo. Sin embargo, la creencia de que se asocian con infecciones respiratorias está provocando que se limite su consumo o se sustituya por bebidas vegetales. El objetivo del estudio fue analizar si el consumo de lácteos se asocia con determinadas infecciones respiratorias en la infancia. Material y métodos: estudio transversal con 169 voluntarios de entre 4 y 7 años. Información recogida mediante cuestionarios en papel. Información dietética recogida mediante cuestionario de frecuencia de consumo de alimentos semicualitativo de 151 ítems. Se valoró la asociación del consumo de leches, quesos y yogures con determinadas enfermedades respiratorias (otitis media aguda, sinusitis, mastoiditis, neumonía), comparando dos categorías de consumo definidas a partir de la mediana de cada alimento, mediante regresión logística multivariable. Resultados: no se encontraron asociaciones entre el consumo de lácteos y las enfermedades respiratorias analizadas (odds ratio: 0,85; intervalo de confianza del 95%: 0,44 a 1,64]). Al analizar cada lácteo por separado, se encontró una asociación inversa entre el consumo de quesos y las enfermedades respiratorias en conjunto (odds ratio: 0,50; intervalo de confianza del 95%: 0,26 a 0,98), pero no para cada una de las infecciones por separado (otitis media aguda ni neumonía). No se encontró asociación significativa con los desenlaces para ningún otro derivado lácteo (leche o yogures). Conclusiones: los resultados no apoyan una asociación directa entre el consumo de leche y derivados con infecciones respiratorias en la infancia. Con los datos actuales no está justificado restringir el consumo de leche o derivados en niños en edad escolar.
- Consumo de jamón curado e incidencia de eventos cardiovasculares, hipertensión arterial o ganancia de peso(Doyma, 2009) Martinez, J.A. (José Alfredo); Martinez-Gonzalez, M.A. (Miguel Ángel); Zazpe, I. (Itziar); Bes-Rastrollo, M. (Maira); Cuervo, M. (Marta); Ruiz-Canela, M. (Miguel)Fundamento y objetivo: El jamón curado es uno de los alimentos característicos de la dieta mediterránea española. Sin embargo, no existe ningún estudio epidemiológico prospectivo que haya valorado sus efectos sobre la salud humana. Nuestro objetivo fue evaluar la asociación entre el consumo de jamón curado y la incidencia de hipertensión arterial, enfermedad cardiovascular y/o ganancia de peso. Sujetos y método: En una cohorte epidemiológica prospectiva y dinámica de 13.293 graduados universitarios (Proyecto SUN) se analizó la incidencia de enfermedad cardiovascular, hipertensión arterial y la ganancia de peso a lo largo de un seguimiento máximo de 6 años. Se ajustaron modelos de regresión de Cox para estimar hazard ratios (riesgos relativos [RR]) tras ajustar por posibles factores de confusión. Resultados: El consumo de jamón en los niveles más altos (> 4 raciones/semana) no presentaba asociación con la incidencia de eventos cardiovasculares (RR=1,02; [IC 95%: 0,44-2,39]), tras ajustar por edad, sexo, ingesta energética total y patrón dietético, en comparación con los consumos inferiores a una vez por semana. Al repetir esta comparación para la hipertensión, y tras ajustar por edad, sexo, ingesta energética total e índice de masa corporal, se encontró un RR = 0.74 (IC 95%: 0.55-1.01). En la comparación del cambio de peso medio anual entre estas mismas categorías extremas de consumo (<1 versus >=4 raciones) se encontró una diferencia no significativa de 0,033 kg (IC 95%: -0,041 a +0,107) en la ganancia media de peso al año tras ajustar por sexo, edad, tabaco, actividad física e índice de masa corporal inicial. Conclusiones: Los resultados de esta cohorte no proporcionan evidencia de que el consumo de jamón curado se asocie a mayor riesgo cardiovascular, de hipertensión arterial o de ganancia de peso.Background and objective: Cured ham is a characteristic food in Spanish Mediterranean diet. However, no prospective epidemiologic study assessing its effects on human health is available. Our aim was to assess the association between the consumption of cured ham and cardiovascular disease, hypertension or weight gain. Subjects and Method: In a prospective and dynamic epidemiologic cohort composed exclusively of university graduates (the SUN Project, n=13,293), we analyzed the incidence of cardiovascular disease, hypertension or average yearly weight gain after a maximum follow-up of 6 years. Cox (proportional hazards) regression models were fitted to estimate hazard ratios (relative risks [RR]) after adjusting for potential confounding. Results: No association was found between higher levels of consumption of cured ham (> 4 servings/week) and the incidence of cardiovascular disease (RR=1.02; [95%CI]: 0.44-2.39), in analyses adjusted for age, sex, total energy intake and dietary pattern, compared to the consumption of less than one serving a week. When we repeated this comparison for the incidence of hypertension, and adjusting for age, sex, total energy intake and body mass index, the RR was 0.74 (95% CI: 0.55-1.01). In the comparison of average yearly weight gain between these extreme categories of cured ham consumption (<1 versus >=4 servings/week) a non-significant difference of 0.033 kg (95% CI: -0.041 to 0.107) was found after adjusting for sex, age, smoking, physical activity, and baseline body mass index. Conclusions: The results of this cohort study do not support any association between the consumption of cured ham and a higher risk of cardiovascular disease, hypertension or weight gain.
- Beneficial changes in food consumption and nutrient intake after 10 years of follow-up in a Mediterranean cohort: the SUN project(BioMed Central, 2016) Martinez-Gonzalez, M.A. (Miguel Ángel); Fuente-Arrillaga, C. (Carmen) de la; Zazpe, I. (Itziar); Bes-Rastrollo, M. (Maira); Santiago, S. (Susana); Ruiz-Canela, M. (Miguel); Gea, A. (Alfredo)Abstract Background: The assessment of changes in dietary habits provides interesting information on whether or not the observed trends are in line with accepted nutritional guidelines. The objective was to evaluate within-subject longitudinal changes in food consumption and nutrient intake and in a 10-year follow-up study. Methods: The SUN (Seguimiento Universidad de Navarra) project is a prospective Spanish cohort study. Diet was assessed using a 136-item food-frequency questionnaire (FFQ), previously validated in Spain. The participants were 3036 university graduates (55.8 % women) of Spain and the main outcome measures the changes in dietary quality and in food consumption and nutrient intake. Paired t-tests and conditional logistic regression models were used to evaluate within-subject longitudinal dietary changes and the risk of inadequacy respectively, after 10 years of follow-up. Results: During follow-up, participants showed a relevant and significant increase (p < 0.001) in the consumption of fruits (7.4 %), vegetables (8.6 %), low-fat dairy products (35.2 %), lean meat (12.4 %), fish (2.9 %), whole grains (53.2 %), nuts (52.4 %) and a significant decrease in legumes (−7.4 %), whole-fat dairy products (−44.2 %), red meat (−17.6 %), sugar-sweetened beverages (−58.7 %) and wine (−11.9 %). With respect to nutrients, we found a higher proportion of carbohydrates (3.6 %) and fiber (7.4 %) and a decrease in total energy intake (2.7 %), total fat (−4.5 %), SFA (−9.4 %), MUFA (−4.9 %), PUFA (−12.7 %), w-3 and w-6 fatty acids (−9.1 and −20.5 % respectively) and cholesterol (−9.6 %). Conclusions: In this Mediterranean cohort study, mainly beneficial changes in the consumption of most foods and macronutrients were observed after 10 years of follow-up.
- Associations between overall, healthful, and unhealthful low-fat dietary patterns and breast cancer risk in a Mediterranean cohort: The SUN project(Elsevier, 2023) Martinez-Gonzalez, M.A. (Miguel Ángel); Romanos-Nanclares, A. (Andrea); Sanchez-Bayona, R. (Rodrigo); Zazpe, I. (Itziar); Toledo, E. (Estefanía); Aguilera-Buenosvinos, I. (Inmaculada)Objectives: Dietary patterns may have a greater influence on human health than individual foods or nutrients, and they are also of substantial interest in the field of breast cancer prevention. Beyond the adequate balance of macronutrients, evidence indicates that the quality of macronutrient sources may play an important role in health outcomes. We sought to examine the relationship between healthful and unhealthful low-fat dietary patterns in relation to breast cancer. Methods: We used observational data from a Mediterranean cohort study (the Seguimiento Universidad de Navarra project). We prospectively followed 10 930 middle-aged women initially free of breast cancer during a median follow-up of 12.1 y. We calculated an overall, an unhealthful, and a healthful low-fat diet score, based on a previously validated 136-item food frequency questionnaire and grouped participants into ter- tiles. Incident breast cancer—overall and stratified by menopausal status—was the primary outcome. It was self-reported by participants and confirmed based on medical reports or consultation of the National Death Index. We used multivariable Cox regression models adjusted for potential confounders. Results: During 123 297 person-years of follow-up, 150 cases of incident breast cancer were confirmed. No signifi- cant associations were observed for overall or premenopausal breast cancer. For postmenopausal women, we observed a significant association for moderate adherence to the unhealthful low-fat dietary score and postmeno- pausal breast cancer (comparing tertile 2 to tertile 1; hazard ratio = 2.18; 95% confidence interval, 1.15 4.13). Conclusions: In conclusion, no clear associations were observed, although more research is needed to address the association between an unhealthful dietary pattern and postmenopausal breast cancer risk.

- Relative validity of a semi-quantitative food-frequency questionnaire in an elderly Mediterranean population of Spain(Cambridge University Press, 2010) Martinez-Gonzalez, M.A. (Miguel Ángel); Perez-Bauer, M. (Manuel); Zazpe, I. (Itziar); Toledo, E. (Estefanía); Carrasco, P. (Paula); Pinol, J.L. (Josep L.); Fernandez-Ballarth, J.D. (J. D.); Corella, D. (Dolores); Salas-Salvado, J. (Jordi); Martin-Moreno, J.M. (J.M.)The aim of the present study was to assess reproducibility and relative validity of a self-administered FFQ used in the PREDIMED Study, a clinical trial for primary prevention of CVD by Mediterranean diet in a population at high cardiovascular risk. The FFQ was administered twice (FFQ1 and FFQ2) to explore reproducibility at 1 year. Four 3d dietary records (DR) were used as reference to explore validity; participants therefore recorded their food intake over 12 d in the course of 1 year. The degree of misclassification in the FFQ was also evaluated by a contingency table of quintiles comparing the information from the FFQ2 and the DR. A total of 158 men and women (aged 55-80 years) were asked not to modify their dietary habits during the study period. Reproducibility for food groups, energy and nutrient intake, explored by the Pearson correlation coefficient (r) raneed 0.50-0.82, and the intraclass correlation coefficient ([CC) ranged from 0.63 to 0.90. The FFQ2 tended to report higher energy and nutrient intake than the DR. The validity indices of the FFQ in relation to the DR for food groups and energy and nutrient intake ranged (r) from 0.24 to 0.72, while the ranee of the ICC: was between 0.40 and 0.84. With regard to food groups, 68-83 % of individuals were in the same or adjacent quintile in both methods, a figure which decreased to 55-75 % for enemy and nutrient intake. We concluded that FFQ measurements had :good reproducibility and a relative validity similar to those of FFQ used in other prospective studies.
- Dietary inflammatory index and anthropometric measures of obesity in a population sample at high cardiovascular risk from the PREDIMED trial(Cambridge University Press, 2015) Martinez, J.A. (José Alfredo); Martinez-Gonzalez, M.A. (Miguel Ángel); Fiol, M. (Miquel); Fito, M. (Montserrat); Shivappa, N. (Nitin); Sanchez-Tainta, A. (Ana); Zazpe, I. (Itziar); Rekondo, J. (J.); Ros, E. (Emilio); Ruiz-Canela, M. (Miguel); Estruch, R. (Ramón); Santos-Lozano, J.M. (José M.); Lamuela-Raventos, R.M. (Rosa Maria); Serra-Majem, L. (Luis); Corella, D. (Dolores); Fernandez-Crehuet, J. (Joaquín); Pinto, X. (Xavier); Salas-Salvado, J. (Jordi); Hebert, J.R. (James R.)The dietary inflammatory index (DII) is a new tool to assess the inflammatory potential of diet. We aimed to determine the association between the DII and body mass index (BMI), waist circumference and waist to height ratio (WHtR). We conducted a cross-sectional study of 7,236 participants recruited into the PREDIMED trial (PREvención con DIeta MEDiterránea). Information from a validated 137-item food frequency questionnaire was used to calculate energy, foods and nutrients. A 14-item dietary screener was used to assess adherence to the Mediterranean diet (MeDiet). Sex-specific multivariable linear regression models were fitted to estimate differences (and 95% confidence intervals) in BMI, waist circumference and WHtR across quintiles of the DII. All nutrient intakes, healthy foods and adherence to the MeDiet were higher in the quintile with lowest DII score (more anti-inflammatory values) except for animal protein, saturated and monounsaturated fat. Though an inverse association between DII and total energy was apparent, the DII was associated with higher average BMI, waist circumference and WHtR after adjusting for known risk factors. The adjusted difference in WHtR for women and men between the highest and lowest quintile of DII was 1.60% (95% CI 0.87-2.33) and 1.04% (95% CI 0.35-1.74), respectively. Pro-inflammatory scores remained associated with obesity after controlling for the effect that adherence to a MeDiet had on inflammation. In conclusion, this study shows a direct association between the DII and indices of obesity and supports the hypothesis that diet may have a role in the development of obesity through inflammatory modulation mechanisms.
- Association between parental attitudes towards their offspring's diet and children's actual dietary habits - The SENDO project(Scielo, 2021) Moreno-Galarraga, L. (Laura); Romanos-Nanclares, A. (Andrea); Martin-Calvo, N. (Nerea); Zazpe, I. (Itziar); Santiago, S. (Susana); Benítez-Borja, A (Andrea)Introduction: the preschool stage is a critical period for teaching and modeling healthy habits to positively influence children's health and wellbeing throughout their lifetime. Objectives: to evaluate the association between parental attitudes towards their offspring's dietary habits in Spanish children aged 4 to 7 years participating in the Follow-up of Children for Optimal Development (SENDO) project. Methods: we defined an index to measure information on parental attitudes towards their offspring's diet (0 to 8 points), and another one to measure children's actual dietary habits (0 to 19 points). A higher score meant healthier attitudes and healthier habits, respectively. Information was collected through an online questionnaire completed by parents. We calculated crude and multivariable-adjusted odds ratios (OR) and 95 % confidence intervals (CI) for children's healthy dietary habits associated with parental scores in the parental attitudes index. Generalized estimation equations (GEE) were used to account for intra-cluster correlation between siblings. Results: a total of 423 preschoolers (52.3 % boys, mean age 5.3 years) were included in the analyses. Half of the children (51 %) reported unhealthy dietary habits, whereas 56 % of parents reported high adherence to the healthy eating index. Compared to those in the lowest category, the children whose parents were in the highest category in the parental attitudes index showed significantly higher odds of having healthy dietary habits (OR: 2.91; 95 % CI: 1.30-6.53, p for trend = 0.004). Conclusions: our results support a direct association between parental attitudes and their offspring's dietary habits, suggesting that public health interventions aimed at improving children's dietary habits should shift from the individual- to a family-based approach.
