RESUMO
INTRODUCTION: Almost 281 million people were living in a foreign country in 2022, and more than 100 million were displaced because of war conflicts and human right violations. Vaccination coverage of infectious diseases in migrants from some disadvantaged settings could be lower than reception countries populations, consequently seroprevalence studies and better access to vaccination could contribute to reducing these differences. METHODS: A descriptive retrospective cross-sectional study was conducted including migrants, living ≤5 years in the reception country and ≥16 years old, who requested a medical exam between January 1st, 2020 and January 31st, 2021. Seroprevalence assessment was performed, and vaccination was offered to those individuals without immunity to hepatitis B, hepatitis A, varicella, measles, mumps, and rubella. RESULTS: A total of 315 migrants were attended during the study period. Immunity protection at arrival was 252/296 (85.1%) for measles, 274/295 (92.9%) for rubella, 257/296 (86.8%) for mumps, 264/295 (89.5%) for varicella, 267/313 (85.3%) for hepatitis A, and 104/300 (34.6%) for hepatitis B. The final immunity protection after full vaccination schedules was 278/296 (93.9%) for measles, 287/295 (97.3%) for rubella, 274/296 (92.6%) for mumps, 276/295 (93.6%) for varicella, 280/313 (89.5%) for hepatitis A, and 139/300 (46.3%) for hepatitis B. CONCLUSIONS: The vaccination intervention has increased immunity rates for the studied diseases in the attended migrants in our center, however, such interventions should be maintained to reach local population immunization levels. Moreover, the collaboration between shelter and reference specialized health centers is fundamental to implement such vaccination programs.
RESUMO
OBJECTIVE: To assess the self-perception of nurses and general practitioners (GPs) toward Physical Activity on Prescription (PAP) in Madrid Primary Health-Care (PHC). DESIGN: A survey-cohort study. SITE: Nurses and GPs of Madrid PHC System. PARTICIPANTS: A total of 319 GPs and 285 nurses' responders. MEASUREMENTS: Data were analyzed under a classification tree analysis by four predictor variables: (i) Health professional (Nurses/GPs); (ii) Exercise prescription collaboration with all health professionals: physicians, nurses, psychologists, physical therapists, sports medicine physicians, sports scientists, nutritionists, and teachers (Yes/No); (iii) PA promotion collaboration with Sports Scientists (Yes/No); and (iv) The stage of change of PHC staff to PA promotion (0-4 Likert scale). RESULTS: Regarding the predictor variable (i), responders without PA guidelines knowledge and positive attitude to collaborate with nurses in PA promotion are more GPs of female sex (nurses n=33 and GPs n=175) than male sex (nurses n=3 and GPs n=59) (p<.001). For the predictor variable (ii) only 9.30% of PHC staff with a positive attitude to collaborate with all health professionals in PA promotion and exercise prescription. For the predictor variable (iii) was shown low collaboration with sports physicians and sports scientists under a multidisciplinary PAP approach (26.50% responders). Finally, in the predictor variable (iv) Staff maintaining PAP for at least 6 months, self-considered active, and with PAP knowledge want to collaborate with Sports scientists (Yes=233; No=133). CONCLUSIONS: Nurses and GPs are conscious of health-related PA benefits despite the lack of PAP knowledge and lack of willingness to collaborate with other health personnel, exercise professionals, and community resources available.
RESUMO
Lifestyle, a major determinant of health status, comprises a number of habits and behaviours that form a part of daily life. People with healthy lifestyles have a better quality of life, suffer less disease, and have a longer life expectancy. This work reports the design and content validation of a questionnaire-the 'PONTE A 100' questionnaire-assessing the lifestyle of adults. This collects information across five dimensions-'Eating Habits', 'Physical Activity', 'Smoking and use of Alcohol and other Drugs', 'Emotional Wellbeing', and 'Safety and Non-intentional Injuries'-via the answering of a total 33 items. Psychometric validation of the instrument's content was obtained via expert opinions. This was performed by two rounds of assessment and involved 34 experts representing different health science disciplines (mean experience, 27.4 ± 9.4 years). At the end of each round, adjustments were made according to their recommendations. Agreement between the experts was examined using the Aiken V test. A final V value of 0.95 (95% CI, 0.90-1.00) was obtained for the questionnaire as a whole, highlighting the validity of its content. The questionnaire would therefore appear to be an appropriate instrument for assessing the lifestyle of adults.
RESUMO
This study investigates perception and production of the Catalan mid-vowel /e/-/É/ contrast by two groups of 4.5-year-old Catalan-Spanish bilingual children, differing in language dominance. Perception was assessed with an XAB discrimination task involving familiar words and non-words. Production accuracy was measured using a familiar-word elicitation task. Overall, Catalan-dominant bilingual children outperformed Spanish-dominant bilinguals, the latter showing high variability in production accuracy, while being slightly above chance level in perception. No correlation between perception and production performance could be established in this group. The effect of language dominance alone could not explain the Spanish-dominant participants' performance, but quality of Catalan input (native vs. accented speech) was identified as an important factor behind familiar-word production and the inaccurate representation of the target contrast in the lexicon of the bilinguals' less-dominant language. More fine-grained measurements of experience-related factors are needed for a full understanding of the acquisition of challenging contrasts in bilingual contexts.

BACKGROUND: The objective was to estimate the prevalence of household food insecurity (HFI) depending on sociodemographic factors and its association with lifestyle habits and childhood overweight and obesity. METHODS: Data was collected from 1,938 children aged 2 to 14 years who participated in the "Study about Malnutrition" of the Community of Madrid. Weight and height were obtained through physical examination. Body mass index was calculated as weight/height2 (kg/m2) and the criteria of the WHO were used for determining conditions of overweight and obesity. The participants' parents answered a structured questionnaire about their diet, lifestyle (physical activity and screen time), and food insecurity. The diet quality was assessed with the Healthy Eating Index in Spain and food insecurity, defined as the lack of consistent access to sufficient food for a healthy life, was measured via three screening questions and the Household Food Insecurity Access Scale (HFIAS). Odds Ratios (ORs) and Relative Risk Ratios (RRRs) were estimated using logistic regression models and adjusted for confounding variables. RESULTS: The overall prevalence of HFI was 7.7% (95% CI: 6.6â9.0), with lower values in children 2 to 4 years old (5.7%, 95% CI: 4.0â8.1) and significantly higher values in households with low family purchasing power [37.3%; OR: 8.99 (95% CI: 5.5â14.6)]. A higher prevalence of overweight (33.1%) and obesity (28.4%) was observed in children from families with HFI, who presented a lower quality diet and longer screen time compared to those from food-secure households (21.0% and 11.5%, respectively). The RRR of children in families with HFI relative to those from food-secure households was 2.41 (95% CI: 1.5â4.0) for overweight and 1.99 (95% CI: 1.2â3.4) for obesity. CONCLUSION: The prevalence of HFI was high in the paediatric population, especially in households with low family purchasing power. HFI was associated with lower diet quality and higher prevalence of childhood overweight and obesity. Our results suggest the need for paediatric services to detect at-risk households at an early stage to avoid this dual burden of child malnutrition.

Introduction: Eating disorders (ED) are a multifactorial pathology. In their origin multiple variables are involved to which nowadays a possible enhancing factor is added: the diffusion and promotion of the culture of thinness and the apology of ED through the social media (SM) used by the youngest people. Through the feedback tools of the social networks (likes, comments, visits, retweets, etc.) and the elements of comparison between equals of the most visual SMs, many users come to develop risk behaviours that in turn give feedback to others. In addition, a sense of belonging to a group or tribe is created through communities whose members feel supported and where very restrictive diets are shared in an affective way, as well as ways of hiding these and other behaviours from those who do not belong to the group; both elements make it difficult for professionals and the family to intervene. Due to the extensive use of SMs, the rapid dissemination of all that is published, and the limited control over shared content, it is virtually impossible to control those sites that advocate and promote behaviours that contribute to the development or maintenance of ED. Cyberbullying or intimidation through digital technologies often uses body image criticisms that damage the self-esteem of the most vulnerable. This cyberbullying is a factor increasingly present in young people who have suffered an ED. The key to prevention is considered to be media literacy in the use of SM, as well as parental supervision of the youngest. People at risk or who have already been diagnosed with ED find in these networks the social support they seek but are biased towards risk behaviours, when it is possible for health professionals to use them to the benefit of promoting healthy habits and for recovery from these disorders.
Introducción: Los trastornos de la conducta alimentaria (TCA) son una patología multifactorial. En su inicio están implicadas múltiples variables a las que se les suma hoy en día un posible potenciador: la difusión y promoción de la cultura de la delgadez y la apología de los TCA a través de las redes sociales (RR. SS.) usadas por los más jóvenes. A través de las herramientas de feedback de las redes (likes, comments, visitas, retweets, etc.) y los elementos de comparación entre iguales de las RR. SS. más visuales, muchos usuarios llegan a desarrollar conductas de riesgo que a su vez retroalimentan a otros. Por otra parte, se crea la sensación de pertenencia a un grupo o tribu a través de comunidades cuyos miembros se sienten apoyados y donde se comparten de forma afectiva dietas muy restrictivas, así como formas de ocultarlas y otras conductas a quienes no pertenecen al grupo; ambos elementos dificultan la intervención por parte de los profesionales y la familia. Debido al uso extensivo de las RR. SS., a la rápida difusión de todo aquello que se publica y al escaso control que hay sobre el contenido que se comparte, resulta prácticamente imposible controlar los sitios donde se hace apología y se promueven las conductas que contribuyen al desarrollo o mantenimiento de los TCA. El ciberacoso o intimidación por medio de tecnologías digitales utiliza con frecuencia críticas sobre la imagen corporal que dañan la autoestima de los más vulnerables, y es un factor cada vez más presente en los jóvenes que han padecido un TCA. Se considera que la clave de la prevención reside en la alfabetización mediática del uso de las RR. SS., así como la supervisión parental de los más jóvenes. Las personas en riesgo o ya diagnosticadas de TCA encuentran en estas redes el apoyo social que buscan, pero sesgado hacia las conductas de riesgo, cuando sería posible explotarlas en beneficio de la promoción de hábitos saludables y para la recuperación de estos trastornos.

Introduction: The prevention of eating disorders in secondary schools is important since it is aimed at students with ages in which the individual is most vulnerable and the disorder can become chronic. After reviewing the evidence, outside and within our country, the recommendations assembled will be helpful to design efficient preventive programs for implementation in secondary education. The use of interactive content, approach to risk factors, prevention of obesity, application in early ages, interventions carried out by the center's own staff, inclusion of the gender perspective and evaluation of the programs in a controlled, rigorous and scientific way.
Introducción: La prevención de los trastornos de la conducta alimentaria en los centros educativos de secundaria es importante ya que se dirige a alumnos con edades en las que el individuo es más vulnerable y el trastorno puede cronificarse. Tras la revisión de la evidencia fuera y dentro de nuestro país, se recogen una serie de recomendaciones que nos conducirán a obtener una mayor eficacia a la hora de implementar programas preventivos en la educación secundaria: uso de contenido interactivo, abordaje de factores de riesgo, prevención de la obesidad, aplicación en edades tempranas, intervenciones realizadas por el propio personal del centro, inclusión de la perspectiva de género y evaluación de los programas de forma controlada, rigurosa y científica.

Introduction: Existen ciertos colectivos más vulnerables en la comunidad, como los adolescentes y jóvenes involucrados en actividades lúdicas o deportivas que implican una alta competitividad y que llevan asociada una elevada importancia del peso corporal, que tienen significativamente más riesgo de presentar un trastorno de la conducta alimentaria (TCA). Para una prevención primaria efectiva a nivel comunitario, la evidencia nos indica la conveniencia de dirigir nuestros esfuerzos hacia esos grupos con más riesgo, siendo el paradigma de la promoción de la salud la fórmula más indicada. Se sugiere poner en práctica un enfoque participativo, multimodal e interactivo, basando los programas en la terapia motivacional y la disonancia cognitiva, tratando de que estos sean sostenibles e intentando contar con el apoyo de líderes comunitarios.

Introduction: Eating disorders (ED) are a complex pathology in which numerous etiopathogenic factors intervene, and their approach requires an interdisciplinary approach, which is why nutritional education (NE) should be part of both prevention and treatment programs, since NE aims to modify eating behavior to achieve healthier patterns and, for this, the development of nutritional teaching programs is required, directed to the patients and their environment, focusing on the different factors that condition food choices and attitudes towards feeding. NE in these patients is a fundamental therapeutic tool to achieve normalization of eating behavior, since it will allow to contribute knowledge that facilitates the adoption of healthy behaviors, abandon erroneous ideas, and reduce the irrational fear of certain foods, as well as minimize nutritional risk and normalize eating behavior. The prevalence of eating disorders has been increasing over the years and the concern is such that the different autonomous communities, hospitals, and government entities have developed guidelines and protocols that include NE for the prevention and management of the disease. Scientific evidence and organizations such as the American Society of Parenteral and Enteral Nutrition (ASPEN), the American Dietetic Association (ADA), and the Spanish Society of Clinical Nutrition and Metabolism (SENPE) recognize the importance of NE in the treatment of ED and the participation of nutrition professionals in this area. Therefore, the approach to the prevention of ED must be broad, so that it encompasses vulnerable groups and their environment; in the same way, action protocols for treatment must include NE as one of their pillars, through implementation of nutritional education programs to achieve changes in eating behavior, which can be carried out in the different phases or treatment modalities (hospitalization, day hospital, outpatient clinics, etc.) even though each one has different objectives and addresses different theme areas, and they must be developed in a multidisciplinary way with a delegation of clear functions for each professional, in favor of the recovery and stability of the patient and his sociofamilial environment.
Introducción: Los trastornos de la conducta alimentaria (TCA) son una patología compleja en la que intervienen numerosos factores etiopatogénicos y su abordaje requiere un enfoque interdisciplinar, por lo que la educación nutricional (EN) debe formar parte tanto de los programas de prevención como del tratamiento, ya que la EN tiene como finalidad modificar la conducta alimentaria para alcanzar patrones más saludables y para ello se requiere el desarrollo de programas de enseñanza nutricional dirigidos al paciente y su entorno, incidiendo en los diferentes factores que condicionan las elecciones alimentarias y las actitudes hacia la alimentación. La EN en estos pacientes es una herramienta terapéutica fundamental para conseguir normalizar la conducta alimentaria, ya que va a permitir aportar conocimientos que faciliten la adopción de conductas saludables, abandonar ideas erróneas y disminuir el temor irracional hacia determinados alimentos, así como minimizar el riesgo nutricional y normalizar la conducta alimentaria. La prevalencia de los TCA ha ido en incremento a lo largo de los años y es tal la preocupación, que las diferentes comunidades autónomas, hospitales y entidades gubernamentales han elaborado guías y protocolos donde incluyen la EN para la prevención y el abordaje de la enfermedad. La evidencia científica y organismos como la Sociedad Americana de Nutrición Parenteral y Enteral (ASPEN), la Asociación Americana de Dietética (ADA) y la Sociedad Española de Nutrición Clínica y Metabolismo (SENPE) reconocen la importancia de la EN en el tratamiento de los TCA y la participación de los profesionales de la nutrición en esta área. Por tanto, el enfoque de la prevención de los TCA debe ser amplio, de manera que abarque los grupos vulnerables y su entorno; de la misma forma, los protocolos de actuación para el tratamiento deben incluir como uno de sus pilares la EN mediante la implementación de programas de educación nutricional para conseguir cambios de la conducta alimentaria, programas que pueden llevarse a cabo en las distintas fases o modalidades del tratamiento (hospitalización, hospital de día, consultas externas, etc.) aunque cada uno tenga distintos objetivos y aborde diferentes áreas temáticas. Deberán desarrollarse de forma multidisciplinar con una delegación de funciones clara para cada profesional en pro de la recuperación y estabilidad del paciente y su entorno sociofamiliar.

Introduction: The media, by means of advertising, convey an ideal of unreal beauty associated with positive traits such as popularity, esteem, acceptance, intelligence, etc. This can be one of the factors that compromise emotional and physical health, being responsible for creating unrealistic expectations and body dissatisfaction, and exerting a very important influence on the triggering or maintenance of bad eating habits that can lead to eating disorders. The youngest population has a low capacity to anticipate the harmful effects of certain messages with commercial interests, and this requires implementing preventive programs based on media education, accompanied by modeling in the family nucleus to promote a healthy lifestyle.
Introducción: Los medios de comunicación, a través de la publicidad, transmiten un ideal de belleza no real asociado con rasgos positivos como popularidad, aprecio, aceptación, inteligencia, etc. Esto puede constituir uno de los factores que comprometen la salud emocional y física, siendo responsables de crear expectativas poco realistas e insatisfacción corporal y ejerciendo una influencia muy destacada en el desencadenamiento o mantenimiento de los malos hábitos alimentarios que pueden abocar en trastornos de la conducta alimentaria. La población más joven tiene una baja capacidad para prever los efectos nocivos de ciertos mensajes con intereses comerciales, por lo que se requiere la puesta en marcha de programas preventivos basados en la educación mediática, acompañada de un modelado del núcleo familiar en el que se promueva un estilo de vida saludable.

PURPOSE: There is a considerable literature supporting the role of lipids in fertility. However, little is known about their impact on male and female gametes. Our study aimed to investigate the relationships between lipids levels in serum, follicular fluid and seminal plasma with ovarian response and sperm concentration regardless of age and body mass index (BMI). METHODS: 51 follicular fluid and serum samples of IVF-ICSI cycles and 52 seminal plasma and serum samples of males in the infertility study were analyzed for cholesterol, triglycerides, and non-esterified fatty acids. The parameters used to assess gonadal response were number of mature oocytes in metaphase II and total motile sperm. Differences between groups were studied by means Principal Component Analysis, Kolmogorov-Smirnov test, Pearson correlation, Student's T, and multivariate linear regression. RESULTS: Using a multivariate linear regression model to exclude the effect of the age and BMI, we found that the lipid profile in follicular fluid and plasma influence inversely and significantly on ovarian response and the number of matured oocytes recovered. Moreover, we found that seminal lipid levels are predictors of seminal quality independent of plasma lipid values. CONCLUSION: Our current analysis demonstrates the association of low ovarian response and low number of motile sperms with abnormal lipids levels.

The plasma glycoprotein afamin has been previously identified as an alternative carrier protein for vitamin E in extravascular fluids such as plasma and cerebrospinal, ovarian follicular, and seminal fluids. However, to date, no study has established a relationship between afamin levels and infertility in women or men. The purposes of our study were (i) to assess the level of afamin in serum and seminal fluids in infertile men compared to healthy controls and (ii) to study the association between polymorphisms in afamin genes and male infertility. This observational, prospective study evaluated the afamin levels in serum and seminal fluids from infertile men (n = 39) and compared them to those in healthy controls (n = 30). We studied the association between single-nucleotide polymorphisms (SNPs) in the 5`-untranslated region (5`-UTR) of the afamin gene and infertility and analyzed a total of 1000 base pairs from the untranslated region of the afamin gene. Subjects with low sperm motility and low sperm concentration had higher median seminal afamin (18.9 ± 2.9 ng/mg of proteins) and serum afamin concentrations (24.1 ± 4.0 ng/mg of proteins) than subjects with normal sperm parameters (10.6 ± 1.4 ng/mg of proteins) (p < 0.02) (15.6 ± 1.4 ng/mg of proteins) (p < 0.002). A total of five different polymorphisms were found, including one deletion and four single-nucleotide polymorphisms (SNPs). A new transversion (A/T) (position 4:73481093) was identified in an oligoasthenoteratozoospermic patient and was associated with high levels of afamin in plasma and seminal fluids. The prevalence of this variant in our study in the case homozygous for TT is 0.985 (98.5%), and in the case heterozygous for TA is 0.015 (1.5%). Our results suggest that genetic variations in afamin might be associated with male infertility. These findings could significantly enhance our understanding of the molecular genetic causes of infertility.

Background Bariatric Surgery is the most effective alternative for weight reduction. However, weight regain is a serious problem. Therefore, pre and post-operative psychological management becomes relevant for these patients. Aim To unify criteria about the psychological management patients undergoing bariatric surgery. Material and Methods A questionnaire about psychological practice in bariatric surgery was sent to 50 national expert psychologists, members of the Chilean Bariatric and Metabolic Society. When no agreement among them was achieved, the Delphi methodology was applied. Scores of 86% or greater were used to reach consensus. Results The specialized clinical assessment is crucial for a good preoperative evaluation and to obtain and adequate compliance after surgery. Psychological interventions evolved towards a preparation process to achieve behavioral changes aiming to maintain good long term weight reduction results. Conclusions The indications and recommendations emanating from this consensus generated a document that establishes minimum criteria and quality care standards, which should reduce mental health risks of bariatric surgery and enhance lifestyle changes.

Human natural killer (NK) cells are considered professional cytotoxic cells that are integrated into the effector branch of innate immunity during antiviral and antitumoral responses. The purpose of this study was to examine the peripheral distribution and expression of NK cell activation receptors from the fresh peripheral blood mononuclear cells of 30 breast cancer patients prior to any form of treatment (including surgery, chemotherapy, and radiotherapy), 10 benign breast pathology patients, and 24 control individuals. CD3-CD56dimCD16bright NK cells (CD56dim NK) and CD3-CD56brightCD16dim/- NK cells (CD56bright NK) were identified using flow cytometry. The circulating counts of CD56dim and CD56bright NK cells were not significantly different between the groups evaluated, nor were the counts of other leukocyte subsets between the breast cancer patients and benign breast pathology patients. However, in CD56dim NK cells, NKp44 expression was higher in breast cancer patients (P = .0302), whereas NKp30 (P = .0005), NKp46 (P = .0298), and NKG2D (P = .0005) expression was lower with respect to healthy donors. In CD56bright NK cells, NKp30 (P = .0007), NKp46 (P = .0012), and NKG2D (P = .0069) expression was lower in breast cancer patients compared with control group. Only NKG2D in CD56bright NK cells (P = .0208) and CD56dim NK cells (P = .0439) showed difference between benign breast pathology and breast cancer patients. Collectively, the current study showed phenotypic alterations in activation receptors on CD56dim and CD56bright NK cells, suggesting that breast cancer patients have decreased NK cell cytotoxicity.
RESUMO
The aim of this study was to determine the concentrations of oxidative stress markers, antioxidant enzymes and cytokines in the follicular fluid of young women with low response in ovarian stimulation cycles compared with high responders and fertile oocyte donors of the same age, to assess the impact of oxidative stress on ovarian reserve. The activity of follicular fluid antioxidant enzymes glutathione transferase, glutathione reductase and glutathione peroxidase was significantly lower in young women with reduced ovarian reserve compared with that in high responders and oocyte donors. Follicular fluid concentrations of oxidative stress marker malondialdehyde combined with 4-hydroxyalkenals and nitric oxide were higher in low responders than in high responders and oocyte donors. Significant differences between low responders and donors in concentrations of IL-2, IL-6, IL-8 and vascular endothelial growth factor were observed, with higher concentrations in low responders. However, IL-10 concentration was lower in low responders than in high responders and donors. No significant differences were found in follicular fluid concentrations of tumour necrosis factor alpha between the three groups. These results demonstrate that different concentrations of oxidative stress markers, oxidant enzymes and cytokines in low responders compared with high responders and oocyte donors may negatively impact ovarian response.

Quality of life, dependency and mental health are multidimensional constructs that cannot be observed directly yet can be deduced in an indirect manner through indicators or profiles generated from questionnaires. These questionnaires are based on the validity of information transmitted by the respondents about perceptions, feelings and attitudes. For this reason, the information is difficult to contrast with and translate to a measuring system. The use of questionnaires or rapid quality of life and mental health evaluation scales involve a process directed towards an early identification of specific problems so as to establish medical treatment. This work will review the most commonly used scales or questionnaires in determining these variables and their relationship with the nutritional status of the population.
Calidad de vida, dependencia y salud mental son constructos multidimensionales no observables directamente pero que pueden ser deducidos de manera indirecta a través de indicadores o perfiles generados a partir de cuestionarios. Estos cuestionarios se basan en la validez de la información de percepciones, sentimientos y actitudes que trasmite el encuestado. Por esta razón, esta información es difícil de contrastar y traducir a un sistema de medida. El empleo de cuestionarios o escalas de valoración rápida de la calidad de vida, dependencia y salud mental, conlleva un proceso dirigido a identificar precozmente a sujetos con problemas específicos para poder instaurar programas de intervención. Este trabajo revisa las escalas o cuestionarios más empleados en la determinación de estas variables y su relación con el estado nutricional de la población.

Multidisciplinary experts in the areas of nutrition and health met in Chinchón, Madrid, on November 25-26, 2013 under the auspices of the Fundación para la Investigación Nutricional (Nutrition Research Foundation) and with the collaboration of the Madrid Regional Government's Health Ministry, the International Sweeteners Association and the Carlos III Health Institute CIBER of Physiopathology of Obesity and Nutrition. They analyzed the current status of scientific knowledge on low- and no-calorie sweeteners (LNCS) and developed a consensus Decalogue on their use; this constitutes the Chinchón Declaration. Sweeteners, including sugar, represent a subject of undeniable interest and are currently a popular topic, although areas relating to their safety and benefits remain unknown to segments of academia and the general public. The nature of LNCS makes them vulnerable to biased and even contradictory information. They are food additives that are broadly used as sugar substitutes to sweeten foods, medicines and food supplements when non-nutritional or non-caloric alternatives are needed. The Chinchón Decalogue is the outcome of a meeting for reflection and consensus by a group of experts with backgrounds in different scientific disciplines (toxicology, clinical nutrition, community nutrition, physiology, food science, public health, pediatrics, endocrinology and nutrition, nursing, pharmaceutical care and food legislation). The Decalogue includes different aspects of LNCS related to regulation, use, benefits and safety. In general, benefits of LNCS have been traditionally neglected in comparison with the tendency for emphasising unexisting or unproven possible risks. The need to strengthen research on LNCS in Spain was emphasized, as well as the need to educate both professionals and the public.
Expertos de carácter multidisciplinar de las áreas de conocimiento de la nutrición y la salud reunidos en Chinchón, Madrid, los días 25 y 26 de noviembre de 2013 , bajo los auspicios de la Fundación para la Investigación Nutricional y con la colaboración de la Consejería de Sanidad del Gobierno de la Comunidad de Madrid, la International Sweeteners Association y el CIBER de Fisiopatología de la Obesidad y la Nutrición del Instituto de Salud Carlos III, analizaron el estado actual del conocimiento científico en torno a los Edulcorantes sin y bajos en calorías (ESBC) y desarrollaron un Decálogo sobre su uso que constituye la Declaración de Chinchón. Los edulcorantes, incluido el azúcar, constituyen un elemento de indudable interés y actualidad, aunque no exento de desconocimiento por algunos sectores tanto académicos como de la población en general. La propia naturaleza de los ESBC los hace susceptibles de informaciones tergiversadas e incluso contradictorias. Son aditivos alimentarios ampliamente utilizados como sustitutivos del azúcar para endulzar alimentos, medicamentos y complementos alimenticios cuando se persiguen fines no nutritivos. El Decálogo de Chinchón es fruto de una reunión de reflexión y consenso por parte de un grupo de expertos procedentes de distintas disciplinas científicas (toxicología, nutrición clínica, nutrición comunitaria, fisiología, bromatología, salud pública, atención primaria, pediatría, endocrinología y nutrición, enfermería, atención farmacéutica y legislación alimentaria). El decálogo incluye diferentes aspectos de los EBSC relacionados con la legislación, uso, beneficios y seguridad. En general, los beneficios de los EBSC han sido tradicionalmente desatendidos en comparación con la tendencia de destacar posibles riesgos inexistentes o que no han sido probados. Hace especial hincapié en la necesidad de fortalecer la investigación de los EBSC en España, así como la necesidad de formar en este ámbito a los profesionales y a los consumidores en general.
