  • Ingesta de arsénico: el impacto en la alimentación y la salud humana

    Medina-Pizzali, María; Robles, Pamela; Mendoza, Mónica; Torres, Celeste (Instituto Nacional de Salud (INS), 2018-04-09)
    Arsenic is an element that is widely distributed throughout the environment. Its compounds are mainly in the state of pentavalent and trivalent oxidation; and in inorganic and organic forms. Arsenical species vary in their degree of toxicity, with inorganic compounds being more political than organic, and trivalent compounds more toxic than pentavalent compounds. There would be interconversion between the less toxic species and other more toxic species and the cooking and processing methods could affect it. Arsenic is a carcinogenic agent and causes multiple negative effects on human health in the short and long term. Non-occupational human exposure to arsenic occurs mainly through water and food. The regulation is variable for each country and is based on WHO standards, the Codex Alimentarius, and the European Union. Many studies focus on determining the total arsenic content but do not identify arsenical species in foods. Globally, fish and seafood, chicken, meat, rice, and seaweed have high levels of arsenic. In Peru, there are few studies on total arsenic content and arsenical species in food despite the fact that we have areas with high levels of environmental contamination. The objective of this review is to discuss exposure to arsenic through food and water intake, related regulations, toxicity, consequences on human health and main foods that contribute to its intake.
  • Efecto de la anemia en el desarrollo infantil: Consecuencias a largo plazo

    Zavaleta, Nelly; Astete-Robilliard, Laura (Instituto Nacional de Salud (INS), 2017-12)
    Anemia in children younger than 3 years is a public health problem in Peru and worldwide. It is believed that one of the primary causes of anemia is iron deficiency. Numerous studies and reviews have reported that iron deficiency limited psychomotor development in children and that, despite the correction of anemia, children with iron deficiency experienced poorer long-term performance in cognitive, social, and emotional functioning. These outcomes were reported in observational studies, follow-up studies, and experimental studies with a control group. Anemia can decrease school performance, productivity in adult life, quality of life, and the general income of affected individuals. Here we describe possible mechanisms underlying the effect of iron deficiency, with or without anemia, on childhood development. The high rate of anemia in this age group is a cause for concern. Moreover, anemia should be prevented in the first year of life to avoid long-term negative effects on individual development.

  • Discordancia lipídica y placa carotídea en pacientes obesos en prevención primaria

    Masson, Walter; Siniawski, Daniel; Lobo, Martín; Molinero, Graciela; walter.masson@hospitalitaliano.org.ar (Elsevier España S.L., 2017-11)
    Introduction Obese patients with lipid discordance (non-HDL cholesterol levels 30mg/dL above the LDL-c value) may have a greater prevalence of carotid atherosclerotic plaque (CAP). Our study objectives were: 1) To assess the prevalence of lipid discordance in a primary prevention population of obese patients; 2) To investigate the association between lipid discordance and presence of CAP. Methods Obese subjects aged >18 years (BMI ≥30kg/m2) with no cardiovascular disease, diabetes, or lipid-lowering treatment from six cardiology centers were included. Lipid discordance was defined when, regardless of the LDL-c level, the non-HDL cholesterol value exceeded the LDL-c value by 30mg/dL. Presence of CAP was identified by ultrasonography. Univariate and multivariate analyses were performed to explore the association between lipid discordance and presence of CAP. Results The study simple consisted of 325 obese patients (57.2% men; mean age, 52.3 years). Prevalence of lipid discordance was 57.9%. CAP was found in 38.6% of patients, but the proportion was higher in subjects with lipid discordance as compared to those without this lipid pattern (44.4% vs. 30.7%, P=.01). In both the univariate (OR: 1.80; 95% CI: 1.14-2.87; P=.01) and the multivariate analysis (OR: 2.07; 95% CI: 1.22-3.54; P=.007), presence of lipid discordance was associated to an increased probability of CAP. Conclusion In these obese patients, lipid discordance was associated to greater prevalence of CAP. Evaluation of obese patients with this strategy could help identify subjects with higher residual cardiovascular risk.
  • Traducción, adaptación cultural y validación del Salt Knowledge Questionnaire al idioma español

    Quinteros-Reyes, C.; Marcionelli-Sandhaus, T.; Mayta-Tristan, Percy (Elsevier España, S.L.U, 2017-11)
    Abstract INTRODUCTION: In order to reduce salt consumption in Spanish speaking countries it is necessary to know the level of salt knowledge in the population. However, there are no tools in Spanish to measure salt knowledge, but the only valid tool of measurement is the 'Salt Knowledge Questionnaire' (SKQ) developed in Australia, in English. MATERIALS AND METHODS: A validation study was conducted in three phases: (Phase1) Translation of the original Australian version into Spanish; (Phase2) Cultural adaptation based on a Spanish-speaking population such as Peru and following criteria used in the development of the original questionnaire which was evaluated by a panel of experts; (Phase3) Construct validity by comparing the scores of three groups (experts, medical students and non-experts) and reliability by performing a test retest. RESULTS: The translation of the SKQ into Spanish maintained a semantic equivalence with the original questionnaire and a panel of experts accepted the cultural adaptation. The SKQ enables discrimination between those who know and those who do not because differences of scores were found between the group of experts, students and non-experts (P<.001). A good overall internal consistency of the instrument was found (KR20=0.69) and a good overall intraclass correlation (0.79) and no test variations in test-retest (P>.05). CONCLUSIONS: The SKQ questionnaire in Spanish is valid, reliable and is a suitable first tool to measure knowledge about salt in the Spanish language. It is considered possible to adapt it culturally to the Spanish-speaking country that wishes to use it.

    Rivera Ameri, Alexandra; Quiroz Acurio, Valeria; Arias Montano, Kevyn; valeria_93_2@hotmail.com (Elsevier B.V., 2017-07-24)
    Introducción: El objetivo de este trabajo fue determinar la prevalencia de anemia ferropénica según el componente dinámico y estático, identificando de esta manera los deportes con mayor prevalencia de anemia y determinar la asociación entre el sexo, la edad y anemia.Material y métodos: Estudio observacional de tipo corte transversal analítico. Se utilizó la base de datos de la Dirección Nacional de Servicios Biomédicos del Instituto Peruano del Deporte, en el periodo de enero a diciembre de 2013. De un universo de 1833 deportistas, se seleccionaron aquellos entre 18 y 35 años de edad. Las variables numéricas se evaluaron usando la prueba de t de Student o la prueba de Mann-Whitney dependiendo del estado de normalidad de las variables. Las variables categóricas fueron evaluadas usando χ2. Razones de prevalencias crudas y ajustadas fueron calculadas usando regresión de Poisson con varianza robusta, para evaluar la asociación entre sexo y anemia.Resultados: Se analizaron 633 deportistas, siendo en su mayoría varones (68,4%). Las variables que se incluyeron en el modelo bivariado fueron sexo, edad deportiva y suplementación con hierro, las cuales fueron también incluidas en el modelo multivariado, encontrándose asociación entre anemia y edad deportiva (p=0,01). No se encontró asociación entre sexo y anemia (RPa= 0,96; IC95%: 0,60-1,40; p=0,85), sin embargo, la prevalencia de anemia fue por encima del 15% (17,9% hombres y 16,8% mujeres).Conclusiones: Se halló mayor prevalencia de anemia ferropénica en los deportes de alto componente estático y dinámico. No se encontró asociación entre anemia ferropénica y sexo en deportistas seleccionados del Instituto Peruano del Deporte en el año 2013.

    Giacchetti-Vega, Monica; Baquerizo-vonBerswordts, Pamela; Carbone-Moane, Camila; Bernabé Ortiz, Antonio; m.giacchetti4@gmail.com (Fundación Española de Dietistas-Nutricionistas (FEDN), 2017-04-04)
    Introduction: The aims of this study were to determine the proportion of patients who meet international recommendations for bariatric surgery and to assess the association between weight loss and dropout rate during diet therapy. Material and Methods: Retrospective cohort study performed using data from clinical records of patients who underwent sleeve gastrectomy in a private clinic of Lima, Peru. Two outcomes were evaluated, eligibility for bariatric surgery according to international recommendations (BMI≥40kg/m2 or ≥35kg/m2 with comorbidities) and abandonment before and after starting nutritional management (no nutritional assessment after 60 days from the previous visit without achieving ideal BMI). The exposure was the percentage of weight lost in the first five weeks after surgery split into <10% and ≥10%. Poisson regression was used and relative risks and 95% confidence intervals (95%CI) were calculated. Results: Data from 423 medical records of bariatric patients, mean age 39.2 years (±12.3), 294 (69.5%) women, were analyzed. Only 117 (27.7%) patients met international recommendations for bariatric surgery. Before starting nutritional management, 48/117 (41%) abandoned treatment, whereas an additional 29/69 (42.0%) abandoned before six months of nutritional management. Patient losing ≥10% of weight in the first month had 90% lower risk (RR=0.10; 95%CI:0.01-0.68) of nutritional therapy dropout compared to those who lost <10% of weight, controlling for sex and age. Conclusions: A great proportion of patients undergoing bariatric surgery did not meet the international criteria. A greater loss of weight during the first month was associated a lower dropout rate during nutritional therapy.

    Cornejo Monthedoro, Angela Patricia; Negreiros Sánchez, Isel Luisa Valeria; Del Águila Villar,Carlos; Ysla Marquillo, Marlit; Mayta-Tristan, Percy; angela_022007@hotmail.com (Sociedad Argentina de Pediatria, 2017-08-01)
    Objective. To study the association between the metabolic syndrome (MS) and the glycemic load (GL) of food intake among obese children and adolescents seen in consultation by the endocrinology team in a pediatric referral hospital in Lima, Peru. Population and Method. Cross-sectional study among obese children and adolescents (body mass index ≥ 95 percentile), 10-15 years old. The MS was classified according to criteria of the International Diabetes Federation. A 24 hour reminder was used, and the overall and per meal GL was calculated. The association between the GL tertiles (comparison with the lower tertile) and the MS was assessed using prevalence ratios adjusted by demographic outcome measures, family history, physical activity and total carbohydrate consumption in Poisson regression models with a robust variance. Results. Out of 273 obese children and adolescents, 52.4% were male and 94.9% did not engage in any physical activity. Glycemic load median value was 213 (164.8-287.4) and the daily calorie intake value was 2275 (1851-3024) kcal, consisting mainly of carbohydrates (62%). MS prevalence was 22.3%; the most prevalent components were abdominal obesity (81.7%) and low values of high density lipoprotein (HDL) (63.7%). Lastly, an association was observed between a high consumption of GL and the risk of developing MS (aRP 4.5; 95% CI: 1.3-15.3). Conclusions. There is an association between a high consumption of GL and the presence of MS among obese children and adolescents.

    Objectives. To assess the nutritional status, physical activity, and eating habits of schoolchildren in Cercado de Lima (Lima district). Materials and methods. Cross-sectional descriptive study. The sample included schoolchildren from first to fourth grade in four public elementary schools located in Cercado de Lima. The study variables were nutritional status, hemoglobin dose, physical activity, and eating habits. The percentages of the qualitative variables and central tendency measures for quantitative ones were calculated. The t-test and chi-squared test were applied to analyze differences between both genders. Results. Of 824 schoolchildren included in the study, 24% were obese, 22% were overweight, 5% had short stature, and 11.9% had anemia; in all instances, there were no substantial gender differences. More than 40% of schoolchildren would eat crackers and drink packaged juice and/or soda two or more times a week. In addition, 28% of schoolchildren were inactive; there were significant differences in both genders (P<0.05). Conclusions. Obesity is an ongoing problem with higher rates than overweight and, together, the aforementioned problems affect almost 50% of schoolchildren surveyed. Similarly, the study revealed patterns associated with a sedentary lifestyle and frequent consumption of foods with high levels of sugar, salt, and/or fats.
