    El síndrome metabólico (SMet) está asociado con el desarrollo de enfermedades crónicas no transmisibles. Los enfoques dietéticos tradicionales se centran en brindar orientación nutricional, aunque existen barreras psicológicas, interpersonales y culturales que dificultan la adherencia a un estilo de vida saludable como la dieta mediterránea (DMed). El objetivo del estudio es identificar factores reportados por pacientes que limitan o facilitan la adherencia a una DMed en pacientes chilenos con criterios diagnósticos de SMet. Se trabajó bajo un enfoque cualitativo, mediante entrevistas individuales y grupales con 17 pacientes chilenos con elementos del diagnóstico de SMet. Las entrevistas estuvieron orientadas por un guion temático donde se indagó actitudes, sentimientos, experiencias y reacciones que actúan como barreras o promotores para el inicio y mantenimiento de DMed como intervención nutricional para prevención de enfermedades crónicas. Los participantes reportaron que el desconocimiento de técnicas culinarias apetecibles, la falta de tiempo y de apoyo activo o participación familiar dificultan la implementación de una DMed a largo plazo. Por el contrario, se encontraron factores facilitadores a la adherencia como menos carga de trabajo o responsabilidades domésticas, no tener hijos o vivir con hijos mayores y la necesidad urgente de cambio a un estilo de vida saludable.

    Background: a healthy food intake pattern, specifically the Mediterranean diet (MedDiet), is a factor associated with reduced risk, lower prevalence, and better management of chronic diseases. However, there is limited information regarding how patients integrate proposals for adherence to this food pattern in their daily lives. Objective: to identify factors and conditions that influence adherence to the MedDiet in Chile. Methods: an exploratory qualitative study was applied in 35 to 65-year-old patients of both sexes who presented at least one diagnostic criterion of metabolic syndrome (MetS). Through in-depth interviews and focal groups, knowledge, assessment, attitudes, and practices associated with changes and maintenance of healthy eating habits, with emphasis on the MedDiet, were investigated. Information analysis was carried out under the grounded theory approach using the ATLAS.ti software. Results: participants recognized the value of healthy eating, including the MedDiet, but declared low knowledge (identification of single foods items) together with facilitators (variety of ingredients) and limiting factors (taste, availability/cost of some items, family dynamics) for its routine adoption. In addition, change in eating habits generates a high initial cognitive and emotional load that requires not only individual but also relational effort as it implies modifications of family and collective practices. Conclusions: information obtained on barriers and opportunities to adhere to healthy eating such as the MedDiet is key to design and implement nutritional interventions based on this food pattern and that can be sustainable in time for chronic disease management in Chile.

    Mediterranean diet and psychological well-being intervention to reverse metabolic syndrome in Chile (CHILEMED trial)

    Psychosocial status and lifestyle are key risk factors of non-communicable diseases (NCDs), which, in turn, are main drivers of healthcare costs and morbimortality worldwide, including Chile. Mediterranean diet (MedDiet) is one of the healthiest dietary patterns under study. However, its impact on high-risk conditions, such as metabolic syndrome (MetS), and NCDs outside the Mediterranean Basin remains mostly unexplored. Even though Central Chile has an environment, food production, and culinary traditions comparable to those present in Mediterranean countries, few studies -some with significant methodological limitations- have evaluated the effect of MedDiet on health and/or disease in Chilean subjects. Importantly, a Mediterranean lifestyle is a modus vivendi that integrates physical health with mental and social well-being. Psychological well-being (PWB) is associated with healthy behaviors, positive health outcomes, and longevity, thereby emerging as a novel healthcare goal. We report here an ongoing randomized controlled clinical trial in Chilean patients with MetS seeking to test whether (1) a PWB theory-based intervention facilitates induction to and increases long-term adherence to a locally adapted MedDiet, and (2) a MedDiet intervention -implemented alone or combined with well-being promotion- is more effective at reversing MetS compared to individuals following a low-fat diet without psychological support. The CHILEan MEDiterranean (CHILEMED) diet intervention study is a 1-year trial including patients with MetS living in Chile. Participants will be assigned randomly by a computer-generated random number sequence to one of the three intervention arms: a) low-fat diet as control group, b) MedDiet alone, and c) MedDiet plus well-being support. Patients will be followed-up by individual and/or group online nutritional sessions or phone cal as well as 6- and 12-month in-person re-assessment of medical history, medication use, food intake, PWB, anthropometrics/physical exam, and blood collection for laboratory analysis. The primary outcome of the trial will be the effect of the MedDiet -with or without PWB intervention- on overall reversal of MetS compared to low-fat diet alone. Based on a statistical superiority trial, expected impact, and patient loss, the estimated study sample is 339 subjects (113 individuals per arm in 3 equal-sized groups). Currently, we have enrolled 179 patients, predominantly women, evenly distributed by age (group means ranging from 45.7 to 48,9 years-old), 3/4 are obese with almost all of them showing abdominal obesity, 70% are hypertensive, whereas <10% exhibit diabetes. If findings turn out as expected (e.g., MedDiet -with or without PWB intervention- is better than the low-fat diet for reversion of MetS at 1-year follow-up), CHILEMED will provide further beneficial evidence of the MedDiet on NCD risk conditions beyond the Mediterranean region.
