Obesity is a chronic disease with an increasing prevalence in all groups of age, and is associated to increased general mortality and cardiovascular risk. The multidisciplinary non surgical approach must be the treatment of choice for obese subjects. However, the results of such approach among subjects with severe or morbid obesity, are unsatisfactory. In this group of patients, bariatric surgery and specifically gastric bypass achieves good long term results, maintaining a low body mass index, reducing complications and improving quality of life. Considering the widespread practice of bariatric surgery in Chile, the Nutrition Unit of the Ministry of Health formed a task force to propose update guidelines for the surgical treatment of obesity. These guidelines were proposed after a thorough literature review and discussion with groups that practice bariatric surgery using defined protocols. This document provides a summarized version of the guidelines. The first section discusses the background for bariatric surgery and the second part give specific recommendations for patient management and the formation of reference centers for surgical management of obesity.

La transicion demografica y nutricional que vive Chile se ha reflejado en una prevalencia alta y creciente de obesidad y enfermedades cronicas vinculadas a la alimentacion. A pesar de los esfuerzos realizados es poco probable cumplir con las metas sanitarias propuestas para el 2010 en cuanto a reducir la obesidad y el sedentarismo. Como parte de sus funciones el Consejo Asesor en Nutricion y Alimentacion del Ministerio de Salud ha revisado recientemente y definido las prioridades nacionales en este campo. En la opinion del Consejo los esfuerzos debieran orientarse fundamentalmente a fortalecer la estrategia de intervencion nutricional a traves del ciclo vital, a mejorar la capacidad institucional del pais en el ambito de los alimentos, a revisar y modernizar la gestion de los programas alimentarios y a desarrollar una alianza estrategica con las empresas productoras de alimentos, sociedades cientificas, grupos academicos y con los propios consumidores orientada a promover una mayor oferta y consumo de alimentos saludables y a regular la publicidad en este campo. Para avanzar en la meta propuesta se requiere sin duda de una mayor inversion de recursos publicos y privados fundamentalmente orientados a la promocion de estilos de vida saludable, con especial enfasis en alimentacion y actividad fisica

Background: The Ministry of Health incorporated in 2008 in the national supplementary feeding program a milk based drink for pregnant and nursing women fortified with EPA and DHA. The product initially presented some degree of rejection in the population, which led to modify its organoleptic characteristics. Objective: To evaluate in a national sample the acceptability and consumption of the modified product a year after starting distribution. Methodology: Random sample of 1,272 beneficiaries in 62 clinics and 21 rural health posts across the country. A semi-structured survey to assess withdrawal, acceptability and consumption by the beneficiary and other household members was applied. Results: Ninety point seven % of mothers regularly withdrew the product. There were important problems in the preparation of “Purita Mama” by lower dilution (22%) or excessive concentration (50.8%). The overall assessment of the product showed an average of 3 (regular) on a scale of 1 to 5 in pregnant and lactating women, highlighting negative opinions about the excessive sweetness (19.2%) and strong aroma (49.9%). The median overall assessment of the mothers was 3 (regular) on a scale of 1 to 5, without significant differences between pregnant and lactating women. The median consumption of the beneficiaries was 250 ml/day, close to schedule and higher in the nursing women, although they receive more product. Eighty % of mothers appreciate the nutritional benefits of the product to the mother or child. About 60% of mothers do not share the milk drink, which indicates a relatively low domestic dilution. Conclusions: there was no significant change in the level of acceptability of the product and the consumption levels were relatively adequate. It is important to enhance information on how to prepare the product, to propose different alternatives for consumption and eventually to consider alternatives of flavor.

La disminucion de la obesidad es un objetivo sanitario para la decada. Objetivo: Evaluar respuesta antropometrica, metabolica y adherencia a corto plazo, a un modelo de intervencion en obesidad infantil. Sujetos y Metodo: Ninos(as) obesos, 6-19 anos, ingresados a un programa piloto; intervencion multidisciplinaria, de 4 meses de duracion. Se evaluo al ingreso y 4 meses 1MC, perimetro de cintura (PC), lipidos plasmaticos, glice-mia e insulinemia. Resultados: Ingresaron 402 pacientes, 12,2 anos (6,3 a 18,2 anos); 56,5% mujeres, zIMC al ingreso 2,92 (1,7 a 7,7); PC 92,3 ± 11,1cm; HOMA 2,45 (0,37 a 17,79). El 39,1% presentaba un CT > 170 mg/dL; 26,5%; LDL > 110 mg/dL; 30,9% HDL 110 mg/dl. El 66,9% completo el programa, 68,4% de estos bajo el zIMC (3,13 ingreso vs 2,77 cuarto mes, p < 0,05) sin relacion con edad, sexo, ni zIMC inicial. El grupo que completo el programa tenia un zIMC al ingreso significativamente mayor (3,1 vi 2,74, p < 0,05). Del grupo con examenes alterados al ingreso y repitieron al cuarto mes, 54% disminuyeron HOMA, 59% bajaron el CT y 66% los TG, sin relacion con descenso ponderal, disminucion de PC, ni HOMA. Conclusion: Un alto porcentaje de los ninos(as) completa el programa, presentando mayor adherencia quienes tienen zIMC mas alto al ingreso. El programa logra mejoria en estado nutricional y variables metabolicas a corto plazo, y justificaria su aplicacion en atencion primaria de salud.

Introduccion: La JUNAEB evalua la situacion nutricional de los escolares a partir de mediciones de peso y talla obtenidas por profesores de colegios fiscales. Objetivo: Comparar el diagnostico nutricional segun indice de masa corporal (IMC) a partir de mediciones realizadas en escuelas versus el equipo de salud escolar. Hipotesis: Se espera encontrar concordancia entre ambos grupos, Kappa > 0,8. Material y Metodo: Se analizo la concordancia entre ambos grupos, en los diagnosticos nutricionales de alumnos de primero basico de 9 escuelas de Colina. Resultados: Se obtuvo datos de 416 alumnos; la prevalencia de sobrepeso mas obesidad, segun los datos de las escuelas fue 38% y 29% segun equipo de salud (p < 0,05); la prevalencia de bajo peso fue 4,4% y 5,8% respectivamente (no significativo). La concordancia en el diagnostico nutricional tiene un Kappa de 0,56. Conclusiones: Se demuestra baja concordancia en el diagnostico nutricional entre ambos grupos, haciendose indispensable la revision del proceso de evaluacion de la situacion nutricional de nuestros escolares

Background: The nutritional impact of CONIN nutritional recovery centers must be evaluated, considering the current epidemiological situation in Chile and the new therapeutic focus giving more emphasis to ambulatory treatment. Aim: To analyze the nutritional status of children treated at traditional CONIN centers, the reason for their admission and the factors associated with changes of weight for age index during the hospitalization. Patients and Methods: During the year 2000, the records of 561 patients discharged from the traditional CONIN centers throughout the country were retrospectively analyzed. The changes in weight and height during admission and the possible factors influencing these changes, were determined. Results: The average lapse of stay was 3.9 months; 78% of children had concomitant diseases at admission and 18.7% required to be admitted in a general hospital. One third was admitted with normal weight or even overweight according to the weight for age index, and 31.1% was undernourished. During admission in CONIN, the number of undernourished patients was reduced by 50%, while the proportion of children with normal nutritional status increased by 15% (p <0.001). On admission, 7.8% of children had a low height for age, evidencing a chronic undernutrition. This figure did not change on discharge. The increase of weight/age and weight/height was substantially higher in children with a greater initial deficit (p <0.001). Conclusions: Admission to a CONIN center had a low nutritional impact, and a high risk of a lengthy stay. The most favorable impact could be appreciated in children that were effectively undernourished. Admissions are motivated mainly by social issues, over and above nutritional problems (Rev Med Chile 2003; 131: 1031-36).

The contamination of fish with methylmercury (MeHg) could hamper the health promoting properties of fish. Currently, there is strong evidence about the health benefits of seafood consumption. When consumed by the mother before and during pregnancy it improves neurodevelopment of infants and toddlers. Thereafter it reduces the risk of cardiovascular and other chronic diseases. The benefits of fish are mainly due to its content of omega-3 long chain polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Other constituents, such as high biological value proteins, fat-soluble vitamins, minerals and trace elements contribute to the benefits. On the other hand, there is also convincing evidence about the adverse effects of MeHg on neurodevelopment both during gestation and in early childhood. We herein review the effects of mercury on health. Based on international evidence and new data on the mercury content in Chilean fish, we also propose a recommendation for fish consumption for our population.The contamination of fish with methylmercury (MeHg) could hamper the health promoting properties of fish.

Antecedentes: En Chile, aun el 3,7% de los ninos(as) menores de 6 anos presenta deficit nutricional, los que son incorporados a un programa de refuerzo nutricional cuya evaluacion permanente ha contribuido a mejorarlo. Objetivo: Evaluar la aceptabilidad y consumo de un nuevo producto (Mi Sopita) y de los principales factores asociados a la frecuencia y cantidad consumida. Material y Metodo: Estudio de prevalencia en una muestra representativa de 2 885 beneficiarios de 20 Servicios de Salud. Encuesta estructurada a la madre sobre retiro, frecuencia y forma de consumo, aceptabilidad y dilucion intrafamiliar. Resultados: 85% de las familias retiran regularmente el alimento, 60% de las madres consideran que al nino (a) le gusta, 50% diluye el producto en la familia. El consumo promedio fue de 4,5 ± 2,1 dias semanales, 1,5 ± 0,6 raciones diarias de 39,7 ± 22,0 gramos cada una, sin diferencias significativas por edad o estado nutricional integrado. La variable mas determinante para el consumo fue la opinion de la madre sobre la aceptabilidad por el nino (a) y en menor grado la frecuencia de retiro, la dilucion intrafamiliar y una relacion peso-edad inicial < de 2 DE. Conclusiones: El producto tiene una adecuada aceptabilidad y consumo. La dilucion intrafamiliar es menor que para los alimentos tradicionales. Es fundamental reforzar la educacion al equipo de salud y la familia para mejorar la valoracion social, el consumo y eventualmente el impacto nutricional

Introduccion: La evaluacion del perimetro cefalico (PC) constituye una valiosa herramienta que alerta sobre alteraciones del desarrollo del lactante. Objetivo: Conocer la situacion de medicion del PC en los controles de salud. Metodo: Revision retrospectiva de todos los registros de PC en los controles de ninos de 18 a 24 meses de edad, de julio de 2002 a la fecha, atendidos en dos centros de salud de Colina, consignando el PC, el diagnostico y las indicaciones y reclasificandolo (NCHS) para diagnostico comparativo. Resultados: Se revisaron 424 controles de salud contenidos en 58 fichas, de los cuales 85,3% tenian registro del PC. De ellos el 17.7% tenia consignado el diagnostico. Al clasificar nuevamente los diagnosticos encontrados segun las curvas del NCHS, se encontro que 14% de los registros correspondia a un PC fuera del rango normal y no tenia diagnostico registrado, el unico caso en que se registro diagnostico de alteracion del PC no se registro la conducta tomada. Un 92.2% de los diagnosticos fueron catalogados concordante con el equipo investigador. Conclusiones: La medicion del PC se realiza en la mayoria de los controles, pero no conduce a un diagnostico y manejo terapeutico. Falta reforzar la importancia y utilidad de esta herramienta antropometrica para una adecuada pesquisa diagnostica y una derivacion oportuna a especialista
