Abstract: In 1981, the WHO and its member countries adopted the International Code of Marketing of Breast milk Substitutes (CODE) to regulate the marketing of infant feeding products. Objective: To eva luate compliance with the CODE in Santiago, identifying the most frequent violations. Subjects and Method: The WHO protocol was applied between June and September 2017 to evaluate the CODE compliance in family health centers (CESFAM) and maternity hospitals (MH) by interviewing 451 mothers and 164 healthcare professionals. In addition, advertising of breastmilk substitutes (BMS) and CODE violations in the media, points of sale (small stores n = 70 and large stores n = 10), and labels of these products were evaluated. Results: In this study, 21% of mothers of newborn infants, 52% of mothers of infants younger than six months, and 71% of mothers of infants older than six months reported receiving instructions on BMS. Exposure to advertising of BMS exceeded 80%, while 4.7% and 2.9% received free samples or discount coupons, respectively. Among healthcare professio nals, 40% from CESFAM and 75% from MH indicated visits from company representatives. Du ring the study period, we found only two television adverts and 59 advertisements on 27 websites. Frequent CODE violations in large stores were offering discounts (70%), special displays (26.5%), and 3,6% promotional gifts. Product label violations were infrequent, however, all labels presented images idealizing product use. Conclusions: CODE violations are common in Santiago, Chile. The country would benefit from adopting all the CODE’s recommendations, improving oversight, and toughening penalties in case of violations.

Resumen: Introducción: En 1981, la OMS y sus países miembros, adoptaron el Código Internacional de Comercialización de Sucedáneos de la Leche Materna (CÓDIGO) para regular la comercialización de productos para ali mentación infantil. Objetivo: Monitorear el cumplimiento del CÓDIGO en Santiago, identificando las violaciones más frecuentes. Sujetos y Método: Entre junio y septiembre de 2017 se aplicó protoco lo OMS para evaluar cumplimiento al CÓDIGO en centros de salud familiar (CESFAM), y materni dades entrevistando 451 madres y 164 profesionales. Además, se evaluó la publicidad de sucedáneos de leche materna (SLM) y violaciones al CÓDIGO en medios de comunicación, negocios pequeños (n = 70), grandes (n = 10) y etiquetas de estos productos. Resultados: Un 21% de madres de recién nacidos, 52% de madres de < 6 meses y 71% de madres de > 6 meses reportaron haber recibido reco mendaciones para uso de SLM. La exposición a publicidad superó 80%, un 4,7% recibieron muestras gratis, 2,9% cupones de descuento. Un 40% de profesionales de CESFAM y 75% de maternidades fueron visitados por representantes de compañías. Hubo solo dos anuncios en televisión, pero 59 publicida des en 27 sitios web durante el periodo estudiado. Las violaciones al CÓDIGO, frecuentes en negocios grandes, ofrecían descuentos (70%), regalos por la compra (3,6%) o exhibían destacadamente los productos (26,5%). Las violaciones en etiquetas fueron infrecuentes, con imágenes idealizando el producto. Conclusiones: Las violaciones al CÓDIGO son frecuentes en Santiago. Sería deseable que en Chile se adoptaran todas las recomendaciones del CÓDIGO, se mejorara la fiscalización existente y se endurecieran las sanciones si hay trasgresiones.

Abstract Objectives: to identify trendand factors associated with adverse birth weight. Methods: cross-sectional design. The analysis uses the 2009-2015 Uruguay Perinatal Computer Systemdata on 303,625 newborns. Results: the prevalence of macrosomia (> 3,999g) has increased from 7.0% to 8.4%. The prevalence of low birth weight (LBW) (< 2,500g) decreased, standing at 6.6% in the last year. The factors that determines more possibilities of LBW were preeclampsia (OR = 4.80; CI95%= 4.57-5.05), inadequate controls (OR = 2.29; CI95%= 2.20-2.39), shorter duration of pregnancy (OR = 2.52; CI95%= 2.50-2.55), previous hypertension (OR = 2.11; CI95%= 1.96-2.27), hypertensive disease of pregnancy (OR = 1.82; CI95%= 1.74-1.90), low prematernal maternal weight (OR = 1.65; CI95%= 1.58-1.74). Macrosomia was associated with type 1 diabetes (OR = 2.21; CI95%= 1.86-2.61), Type 2 or Gestational (OR = 1.78; CI95%= 1.70-1.87), obesity maternal (OR = 2.33; CI95%= 2.24-2.43) and longer gestation duration (OR = 2.62; CI95%= 2.53-2.72). Conclusions: the LBW decreases while the macrosomia increases. The health and nutritional status of women at the beginning of pregnancy, pathologies of the last trimester, smoking, shorter duration of pregnancy and inadequate controls are associated with BPN. Overweight, obesity and metabolic diseases determine macrosomia.

Resumen Objetivos: identificar tendencia y factores asociados al peso al nacer adverso. Métodos: diseño transversal, se analizaron nacimientos entre 2009-2015. El análisis utilizó el Sistema Informático Perinatal de Uruguay, de 2009-2015, datos de 303.625 recién nacidos. Resultados: la prevalencia de macrosomía (>3.999g) aumentó de 7% a 8,4%. La prevalencia de bajo peso al nacer (BPN) (<2.500g) disminuyó situándose en 6,6% en el último año. Los factores que determinaron mayores posibilidades de BPN fueron preeclampsia (OR=4,80; IC95%= 4,57-5,05), inadecuados controles (OR = 2,29; IC95%= 2,20-2,39), menor duración de la gestación (OR = 2,52; IC95%= 2,50-2,55), hipertensión arterial previa (OR = 2,11; IC95%= 1,96-2,27), enfermedad hipertensiva del embarazo (OR = 1,82; IC95%= 1,74-1,90), bajo peso materno pregestacional (OR = 1,65; IC95%= 1,58-1,74). Macrosomía se asoció con diabetes tipo 1 (OR = 2,21; IC95%= 1,86-2,61), tipo 2 o Gestacional (OR = 1,78; IC95%= 1,70-1,87), obesidad materna (OR = 2,33; IC95%= 2,242,43) y duración de gestación (OR = 2,62; IC95%= 2,53-2,72). Conclusiones: existe una tendencia a disminución del BPNy aumento de la macrosomía. La salud y estado nutricional de la mujer al inicio de la gestación, patologías del último trimestre, tabaquismo, menor duración de la gestación e inadecuados controles se asocian a BPN. El sobrepeso, la obesidad y enfermedades metabólicas determinan macrosomía.

The aim of this study was to conduct a review of the health and nutritional status of Chilean indigenous children, specifically Mapuche children, as published in the literature and specific population-based studies. The searches were conducted in PubMed and LILACS in the last 15 years. From 2006 to 2015, the poverty rate was higher in the indigenous population, with a decrease in the gap from 16% in 2006 to 7.7% in 2015 (p < 0.001). In the first decade of this century, infant mortality in indigenous children was 17.1/1,000 live births, while in non-indigenous children it was 8.8/1,000, and the gap was maintained in the five-year follow-up (p < 0.001). Newborns with birthweight < 2,500g in the year 2000 did not reach 6% (5.6% in non-indigenous and 5.2% in indigenous children). Low height at first school enrollment was 8.4% in indigenous schoolchildren and 3.1% in non-indigenous children, decreasing to 3.7% in indigenous children and 2.6% in non-indigenous children in 2004, while obesity increased more in indigenous children, reaching 24.2% in indigenous and 25.3% in non-indigenous children (p < 0.001). Menarche appeared four months later on average in indigenous girls (12.7 years), and body mass index, waist circumference, and fat mass were significantly greater in indigenous girls at the time of thelarche, as was the overweight rate (55%, vs. 42% in non-indigenous). Mapuche children show favorable health and nutritional status compared to indigenous children elsewhere in Latin America, but there is still an adverse gap compared to non-indigenous Chilean children. This inequality affecting indigenous Chilean children should be acknowledged and corrected.

El objetivo de este trabajo fue realizar una revisión de la situación de salud y nutrición del niño indígena chileno, específicamente del Mapuche, en lo publicado en las bases de datos de referencias bibliográficas y en investigaciones específicas que tienen base poblacional. Para este trabajo se buscó lo publicado en PubMed, LILACS, organismos nacionales e internacionales, durante los últimos 15 años. Desde el 2006 hasta el 2015 la proporción de pobres era mayor en los indígenas, con disminución de la brecha de 16% el 2006 a 7,7% el 2015 (p < 0,001). En la primera década de este siglo la mortalidad infantil en los niños indígenas tenía una tasa de 17,1/1.000 nacidos vivos, mientras en los no indígenas era de de 8,8/1.000 y, en el seguimiento de cinco años, la brecha se mantuvo (p < 0,001). Los recién nacidos con peso < 2,500g el año 2000 no superaban el 6% (5,6% en no indígenas y 5,2% en los indígenas). La talla baja al ingreso a la escuela era 8,4% en los escolares indígenas y 3,1% en los no indígenas, disminuyendo a 3,7 en los indígenas y 2,6% en los no indígenas el 2004, la obesidad en cambio aumentó más en los indígenas, llegando a 24,2 y 25,3% en los no indígenas (p < 0,001). La menarquia se presentó cuatro meses más tarde en las indígenas (12,7 años) y el índice de masa corporal, circunferencia de cintura y el porcentaje de grasa, fueron significativamente mayores en las indígenas en el momento de la telarquia, así como la frecuencia de exceso de peso (55% vs. 42% en las no indígenas). Los niños Mapuche presentan una condición de salud y nutrición favorable, comparada con los indígenas de otros países del continente, sin embargo, aun existe una brecha adversa -comparada con los no indígenas-, en que la desigualdad desfavorece al niño indígena y esta debe ser reconocida y corregida.

O objetivo deste trabalho foi realizar una revisão da situação da saúde e nutrição da criança indígena chilena, especificamente da Mapuche, nas publicações relacionadas em bases de dados de referências bibliográficas e em pesquisas específicas que têm base populacional. A pesquisa foi realizada em publicações relacionadas: PubMed, LILACS, organismos nacionais e internacionais, nos últimos 15 anos.

Os recém-nascidos com peso < 2.500g no ano de 2000 não superavam 6% (5,6% em não indígenas e 5,2% nos indígenas). A baixa estatura ao momento do ingresso na escola era 8,4% nos escolares indígenas e 3,1% nos não indígenas, diminuindo a 3,7 nos indígenas e 2,6% nos não indígenas em 2004, a obesidade pelo contrário teve um aumento maior nos indígenas, chegando a 24,2 e 25,3% nos não indígenas (p < 0,001). A menarca ocorreu quatro meses mais tarde nas indígenas (12,7 anos) e o índice de massa corporal, circunferência da cintura e a porcentagem da gordura, foram significativamente maiores nas indígenas no período da telarca, à semelhança da frequência do sobrepeso (55% vs. 42% nas não indígenas). As crianças Mapuche apresentam uma condição de saúde e nutrição favorável, comparada com os indígenas de outros países do continente, no entanto, ainda existe uma brecha adversa - comparada com os não indígenas - , onde a desigualdade desfavorece a criança indígena e por isso deve ser reconhecida e corrigida.

Background: One in five deaths that occur in Chile can be attributed to smoking whose prevalence remains high, despite interventions aimed at reducing it. Aim: To compare the prevalence of smoking and its intensity among young adults born 15 years apart and determine their association with socioeconomic status (SES). Material and Methods: Two cohorts of young adults living in the Valparaiso Region of Chile were evaluated in the third decade of life. Cohort 1 was evaluated between 2000 and 2002 (n = 1232) and cohort 2 between 2014 and 2017 (n = 1078). Results: In cohort 1, 57.5% (95% Confidence Interval (CI) 54.6-58.7) of the subjects reported smoking, with a median of 3 (Interquartile range (ICR:1-6) cigarettes/day. This percentage fell to 40.2% (CI: 37.5-43.1) with a similar median in cohort 2. Analyzing cohort 2, the odds ratio (OR) for smoking was 2.24 (CI 1.48-3.38) in the medium SES, compared with the medium high SES. The figures for low medium and low SES were 2.72 (CI: 1.85-3.99) and 3.01 (1.85-4.88). Similarly, in this cohort there was a significantly higher risk of being a heavy smoker in lower SES. No associations between smoking or its intensity and SES were observed in cohort 1. Conclusions: Smoking behavior has decreased among young adults evaluated at the same age in two generational cohorts in the third decade of life. In the most recent cohort analyzed, smoking and its intensity increase along with a decrease in SES.

Abstract Introduction: Children and young international migrants face different health challenges compa red with the local population, particularly if they live in insecure environments or adverse social conditions. This study seeks to identify gaps in health outcomes of children between immigrant and local population in Chile. Methods: This study analyses data from three sources: (i) Born in Chile: Electronic records of antenatal visits from all municipal antenatal clinics of Recoleta in 2012; (ii) Growing up in Chile: Population survey "National Socioeconomic Characterization" (CASEN) from 2013 and (iii) Getting sick in Chile: Data of all hospital discharges in 2012, provided by the department of statistics and health information (DEIS) of the Ministry of Health. Results: (I) Born in Chile: Im migrants more frequently have psychosocial risk (62.3% vs 50.1% in Chileans) and enter later into the program (63.1% vs 33.4% enter later than 14 weeks of pregnancy). All birth outcomes were better among immigrants (e.g. caesarean sections rates: 24.2% immigrants vs % Chileans). (ii) Growing up in Chile: A higher proportion of migrant children is outside the school system and lives in multidi mensional poverty (40% immigrants vs 23.2% Chileans). (iii) Getting sick in Chile: Injuries and other external causes were more frequent cause of hospitalisation among migrants (23.6%) than the local population (16.7%) aged between 7 and 14 years. Conclusions: Addressing the needs of the children in Chile, regardless of their immigration status, is an ethical, legal and moral imperative.

Resumen Introducción: Los niños y jóvenes migrantes internacionales enfrentan diferentes retos en salud en comparación con la población local, en particular si se enfrentan a ambientes inseguros o a condi ciones sociales adversas. Este estudio busca identificar brechas existentes en resultados de salud de la niñez entre población migrante internacional y chilena. Métodos: Este estudio analiza tres fuentes de información: (i)Nacer en Chile: Datos de consulta antenatal recolectados de los registros electrónicos de las mujeres usuarias del programa Chile Crece Contigo, de todos los centros de salud familiar (CESFAM) de administración municipal de la comuna de Recoleta el año 2012; (ii)Crecer en Chile: Datos de encuesta poblacional "Caracterización Socioeconómica Nacional" CASEN 2013 y (iii)En-fermar en Chile: Datos de todos los egresos hospitalarios de 2012, proporcionada por el departamento de estadística e información en salud (DEIS) del Ministerio de Salud. Resultados: (i) Nacer en Chile: Hay mayor proporción de inmigrantes con riesgo biopsicosocial (62,3% vs 50,1% en chilenas) y con ingreso tardío al programa (63,1% vs 33,4%). Hay menos cesáreas en inmigrantes que en chilenas (24,2% vs 33,6%). (ii) Crecer en Chile: Existe una mayor proporción de niños migrantes fuera del sistema escolar y una mayor proporción en pobreza multidimensional (40% vs 23,2%). (iii) Enfermar en Chile: En migrantes entre 7-14 años es más frecuente egresar hospitalariamente por traumatismos/ otras causas externas (23,6% vs 16,7% en chilenos). Conclusiones: Este estudio entrega nueva evi dencia sobre necesidades urgentes de salud de nuestros niños en Chile. Este es un imperativo ético, legal y moral, independiente de la condición migratoria.

Resumen Las funciones ejecutivas son un grupo de habilidades que permiten la generación de respuestas adaptativas a las exigencias medioambientales. A su vez, la capacidad de mentalización refiere a la forma en que los humanos son capaces de discernir los estados mentales, intenciones y creencias de otros a través de la conducta observada. Este trabajo clarifica la forma en que debiéramos entender la relación entre estos dos conceptos. Tras revisar algunos de los aspectos más fundamentales de los conceptos en cuestión, se propone que la mentalización fundamenta, organiza y potencia el desarrollo de las funciones ejecutivas, esto, en oposición a la tesis dominante de Carlson, Moses y Brenton (2002) que indica que las funciones ejecutivas son las que fundamentan el desarrollo de la habilidad de mentalización. Luego de revisar la actual evidencia empírica que apoya la alternativa propuesta, se exploran algunas aplicaciones de esta en el estudio de la naturaleza neurofisiológica de lo social, la naturaleza subjetiva de la conciencia y el dominio de la psicopatología.

Abstract Executive functions are a set of abilities that allow the production of adaptive behaviours to specific challenges from the environment. Mentalization refers to the way in which humans are able to discern mental states, intentions and beliefs of others through observed behaviour. This paper clarifies the way in which we should understand the relationship between these two concepts. After presenting some of the most fundamental aspects of these concepts, it is proposed that mentalization underlies, organizes, and enhances the development of executive functions, this, contrary to the dominant approach defended by Carlson Moses, and Brenton (2002) that suggests that executive functions underlie the development of mentalization. After reviewing empirical evidence for the defended alternative, the last section explores some of its applications in areas such as the study of the neurophysiological nature of the social, the subjective nature of consciousness, and the domain of psychopathology.

El Índice y Carga Glicémica (IG y CG) categorizan los alimentos según su capacidad de incrementar la glicemia, considerando cantidad y calidad de hidratos de carbono consumidos. Diferentes estudios han postulado que una dieta con IG y CG altos y bajo consumo de fibra incrementan la glicemia e insulinemia, aunque con resultados heterogéneos.El objetivo de este estudio fue analizar la asociación entre IG, CG e ingesta de fibra y valores HOMA-IR en adultos jóvenes. En una muestra representativa de 738 personas que tenían entre 32 y 38 años, nacidos en el Hospital de Limache, Región de Valparaíso, Chile, se recogió información socioeconómica, de salud, se determinó estado nutricional, glicemia, insulina basal y HOMA, y con la encuesta de frecuencia de consumo se estimó IG, CG e ingesta de fibra. Se construyeron modelos de regresión múltiple, controlando efectos de confusión e interacción. En modelos ajustados, se observó que por cada 10 unidades que aumenta el IG y CG de la dieta en individuos con exceso de peso, aumenta el HOMA-IR en 0,31 (p=0,042) y 0,03 (p=0,012), respectivamente y por cada 10 gramos que aumenta la fibra total y soluble, disminuye el HOMA-IR en 0,10 (p=0,04) y 0,62 (p=0,034) respectivamente. En personas sin exceso de peso no hubo estos efectos. Existe una asociación directa entre el aumento de IG y CG de los alimentos y el incremento de HOMA-IR sólo en individuos con exceso de peso y una asociación inversa entre ingesta de fibra dietética total y soluble y HOMA-IR.

Glycemic index, glycemic load and dietary fiber of foods and its association with insulin resistance in Chilean adults. Glycemic index and glycemic load (GI and GL) categorize foods according to their ability to increase blood sugar levels, considering quantity and quality of carbohydrates consumed. Different studies have postulated that a high GI and GL diet and low fiber intake increased glycemia and insulinemia, although with heterogeneous results. The aim of this study was to analyze the association between GI, GL and fiber intake and HOMA-IR values in young adults. In a representative sample of 738 people aged between 32 and 38 years old, born in the Limache’s Hospital, Valparaiso, Chile, socioeconomic and health information, nutritional status, basal glycemia, insulin and HOMA were collected. With a food frequency questionnaire, GI, GL and fiber intake were estimated. Multiple regression models were constructed, controlling confounding and interaction effects. In adjusted models, it was found that for every 10 units that increases diet GI and GL in overweight individuals, HOMA- IR increases in 0.31 (p = 0.042) and 0.03 (p = 0.012) respectively, and for every 10 grams that increases total and soluble fiber intake, HOMA-IR reduces in 0.10 (p = 0.04) and 0.62 (p = 0.034) respectively. In people without overweight such effects were not observed. There was a direct association bet- ween increased GI and GL foods and increased HOMA-IR only in individuals with overweight and an inverse association between total and soluble fiber intake and HOMA-IR.

Background: Metabolic syndrome is highly prevalent among adults in Chile and represents a health risk. Aim: To determine the relationship between metabolic syndrome (MetS) and its components, with C reactive protein levels (CRP) as an inflammation marker. Material and Methods: The population studied consisted of 736 individuals born in a hospital from Valparaíso Region, aged between 32-38 years at the time of the study. MetS was identified according to the Adult Treatment Panel (ATP) III guidelines and inflammation was measured using ultra-sensitive CRP. This parameter was classified as normal for values from 0 to 3 mg/L, high for values from 3.01 to 10 mg/L and very high for values > 10 mg/L. Results: Median CRP was in the normal range (1.9 mg/L, interquartile range 0.7-5.2) and was higher among women than men (2.2 and 1.4 mg/L respectively, p < 0.01). Twenty seven percent of participants had MetS. One-fourth had high blood glucose values, one-third had high triglyceride levels and 28% had blood pressure values over those established as normal in MetS. Elevated waist circumference (WC) and low HDL cholesterol were found among almost 50% of participants. A relationship between MetS and high CRP was only found among men with an Odds ratio (OR) of 2.04 (95% confidence intervals (CI): 1.11-3.73). The same association was observed for high triglyceride levels with an OR of 2.02 (CI: 1.17-3.49) and high WC with an OR of 3.89 (CI: 2.06-7.36). Among women, the only relationship observed was between abdominal obesity and very high CRP with an OR of 2. 65 (CI: 1.20-5.84). Conclusions: Metabolic syndrome, high triglyceride levels, and abdominal obesity were associated with inflammation only in men.

Objective: To analyse the outcomes of births and anthropometric measurements at birth of children born between 1974 and 2011 at Limache Hospital (Valparaíso, Chile). Patients and method: Times series were constructed of births, weight and length at birth, and low weight and length at birth. The trend was modelled with linear and logistical regressions using splines to represent breaks in the trend by decade. Results: The series includes 17,574 births. There was an increase in births per year in the 1970s (30/year) and declines in them to 17 and 22 births/year in the 1980s and 1990s, respectively (P < .001), with no significant trend thereafter. Newborns from 2000 to 2011 weighed 266 grams more than those in the 1970s (P < .001), and have now reached a mean weight of 3,530 g. Low birthweight fell from 8% in the 1970s to 1.1% after 2000. Birth length increased by 1 cm in the 37 years studied, with a reduction of low birth length from 7.6% to 2.1% during the period. Conclusion: Live births in the Limache Hospital declined, and anthropometric measurements at birth improved in the years analysed. This information is useful in developing interventions, taking into account the possible selection biases that could distort these estimates and their interpretation.

Objetivo: Analizar la evolución de los nacimientos y medidas antropométricas al nacer entre 1974-2011 en el Hospital de Limache, Región de Valparaíso, Chile. Pacientes y métodos: Se construyeron series de tiempo de nacimientos, peso y longitud al nacer, peso y talla baja al nacer. Se modelaron las tendencias con regresiones multivariadas usándose splines para representar los cambios de tendencia por década. Resultados: La serie comprende 17.574 nacimientos. Hubo un aumento de los nacimientos/año en los 70 (30/año) y disminución de 17 y 22 nacimientos/año en los 80 y 90 (p < 0,001); después, sin tendencia significativa. Los recién nacidos entre 2000-2011 registran 266 g más que los de la década de los 70 (p < 0,001), alcanzando actualmente en promedio 3.530 g. El bajo peso al nacer disminuyó de 8% en los 70 a 1,1% después de 2000. La longitud al nacer incrementó 1 cm en 37 años, con disminución de la talla baja de 7,6% a 2,1% en el periodo estudiado. Conclusión: Los nacimientos en el Hospital de Limache disminuyeron y las medidas antropométricas al nacer mejoraron; sin embargo, hay que considerar los posibles sesgos que distorsionan estas estimaciones.

Human rhinovirus (HRV) is an emerging viral pathogen. Aim: To characterize a group of patients admitted due to infection by this agent in a general hospital in Chile. Methods: Cases were identified by RT-PCR for 1 year through active surveillance of patients admitted with severe respiratory illness. Diagnosis was not available during hospitalization. Thirty-two cases were identified, 90% were ≥60 years old or had co-morbid conditions. Human rhinovirus-related admissions represented 23.7% of hospitalization due to severe acute respiratory infections among adults and ranked second to influenza (37.8%). Patients presented with pneumonia (68.8%), decompensated chronic lung conditions (21.9%), heart failure or influenza-like illness (6.3% each). Admission to intensive or intermediate care units was required by 31.2% and in-hospital mortality reached 12.5%. A CURB-65 score ≥3 was significantly associated to in-hospital mortality (p < 0.05). Most patients received antibiotics (90%). Conclusions: Human rhinovirus infections in elderly patients with co-morbid conditions are associated with hospitalizations, requiring critical or semi-critical antibiotics use. A high CURB-65 score was associated to in-hospital mortality.

Objective. To estimate the association between the intake of sugar-sweetened non-alcoholic beverages and body mass index (BMI) in Chilean school children. Materials and methods. Food consumption frequency data were analyzed for school children aged 6 to 18. The association between consumption of sugar-sweetened beverages and BMI was estimated by multivariate lineal regression models. Results. Sugar-sweetened beverages are consumed on a daily basis by 92% (95%CI:90-94) of subjects with daily intake medians of 424 mL (p25-p75:212-707). Every extra daily portion of sugar-sweetened beverages consumed by school children aged 6 to 13 is associated with 0.13 BMI z-scores (95%CI:0.04-0.2;p=0.01). Conclusions. School children consume sugar-sweetened beverages daily with intake medians close to 0.5L. There is an association between sugar-sweetened beverage consumption and higher BMI in Chilean school children.

Objetivo. Estimar la asociación entre la ingesta de bebidas azucaradas analcohólicas y el índice de masa corporal (IMC) en escolares chilenos. Material y métodos. Se analizaron datos de frecuencia de consumo de alimentos en escolares de entre 6 y 18 años de edad. Se estimó la asociación entre el consumo de bebidas azucaradas y el IMC a través de modelos de regresión lineal multivariada. Resultados. El 92% (IC95%:90-94) consume bebidas azucaradas diariamente, con medianas de ingesta de 424 ml (p25-p75:212-707).

Se ha descrito que consumir frutas y verduras disminuye la presión arterial. Sin embargo, no está clara la magnitud del efecto según la cantidad consumida. El objetivo de este estudio fue analizar la asociación entre consumo de frutas y verduras, y presión arterial. Se realizó un estudio transversal en una muestra aleatoria de 777 adultos entre 32 y 38 años de la Región de Valparaíso, Chile. Se midió presión arterial sistólica (PAS) y diastólica (PAD), y se aplicó una encuesta de tendencia de consumo cuantificada del último mes. La ingesta de frutas y verduras se dividió en tres grupos: menor a 200 g, 200 a 400 g, mayor a 400 g. Para el análisis se utilizaron modelos de regresión lineal múltiple ajustados por sexo, IMC, actividad física, nivel socioeconómico, tabaquismo e ingesta de sodio. Se observó que a medida que aumenta la ingesta de frutas y verduras disminuye la presión arterial sistólica(β=-3,37; IC 95%: -6,45 a -0,29; en consumo entre 200 y 400 g) (β=- 4,02; IC 95%: -7,06 a -0,98; en consumo mayor a 400 g), mientras que en la presión diastólica solamente se ve el efecto en los que cumplen la recomendación de la OMS de consumir más de 400 g al día (β-2,87; IC=-5,17 a -0,57). Se concluye que consumir frutas y verduras en cantidades mayores a 400 g, tiene un efecto protector en el aumento de la presión arterial tanto sistólica como diastólica.

Consuming fruits and vegetables is known to lower blood pressure. However, it is unclear how much should be consumed in order to achieve this effect. The aim of this study was to analyze the association between fruit and vegetable consumption and blood pressure. A cross-sectional study was conducted among a random sample of 777 adults between the ages of 32 and 38 from the Region of Valparaiso, Chile. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured, and a survey was carried out to quantify consumption trends over the past month. The fruit and vegetable intake was divided into three groups: less than 200 g, 200-400 g, and more than 400 g. In the analysis, multiple linear regression models were used and were adjusted for sex, BMI, physical activity, socioeconomic status, smoking, and sodium intake. It was observed that increasing intake of fruits and vegetables lowers the systolic blood pressure (β = -3.37 , 95% CI : -6.45 to -0.29; for consumption between 200 and 400 g ) (β =-4.02 , 95% CI: -7.06 to -0.98; for consumption great than 400 g), while an effect on diastolic pressure is only seen in those who meet the WHO recommendation of consuming more than 400 g per day (β -2,87, CI = -5.17 to -0.57). In conclusion, consuming fruits and vegetables in amounts larger than 400 g per day, provides a protective effect against increases in both systolic and diastolic blood pressure.

Background: Metabolic syndrome is a risk factor for cardiovascular diseases and cancer. Its frequency is increasing steadily Aim: To evaluate the prevalence of metabolic syndrome (MS) and its components in a 10-year tracking study of young adults. Material and Methods: Concurrent cohort study of subjects born between 1974 and 1978. They were evaluated between 2000 and 2002 and between 2010 and 2012 to determine the frequency of MS and its components (high blood glucose, waist circumference [WC], triglycerides, blood pressure and low HDL cholesterol), according to ATP III criteria. Attrition was handled using the reciprocal of the probability of remaining in the study. Result: During the first evaluation, the prevalence of metabolic syndrome was 9.3%, confidence interval (CI): 7.5-11.1), with no gender differences. Ten years later, the prevalence of MS increased significantly to 27.6% (CI: 24.7-29.9) and was more common in women than men (30.4 and 23.8% respectively, p < 0.014). The components of MS also increased from one period to another: hyperglycemia, from 5.2% (CI: 4-7) to 24.4% (CI: 22-27); high triglyceride levels from 17.6% (CI: 15-20) to 35.3% (CI: 32-38); high blood pressure from 14.7 (CI: 13-18) to 30.2% (IC: 28-33) and high WC: 16.9% (CI: 15-19) to 41.5% (CI: 39-45). In both evaluations, there was a greater frequency of high triglycerides and high blood pressure among men, and greater frequency of low HDL and high WC among women. Hyperglycemia only showed differences by gender in the second measurement, and was greater among men. Conclusions: There was a marked increase in metabolic syndrome and its components in a 10-year interval, which is a warning sign of future cardiovascular risk.
