Abstract: Objetivo. Conocer la influencia del alojamiento conjunto (AC) madre-hijo, en la frecuencia de lactancia humana exclusiva (LHE), desde el nacimiento hasta los cuatro meses de vida. Material y métodos. Estudio de cohortes no aleatorizado realizado en la clínica de lactancia del Hospital "Luis Castelazo Ayala", del Instituto Mexicano del Seguro Social, de enero de 1993 a octubre de 1994, en el que participaron 178 binomios madre-hijo (BMH) sanos con gestación de término. El grupo con alojamiento conjunto (AC) se integró con 90 BMH, y la madre recibió asesoría para lactar; 88 se atendieron en forma separada, sin asesoría para lactar. Se realizó análisis estadístico de los datos para apreciar frecuencia y asociaciones de las variables. Resultados. La alimentación se registró como LHE, fórmula o ambas. Los grupos con y sin AC se estratificaron por la forma de nacimiento, parto o cesárea. Con X2 de Mantel-Haenszel y de rango logarítmico se aceptaron diferencias con p< 0.05. Durante el estudio la lactancia global fue semejante entre los grupos. En el primer mes la LHE fue mayor en el grupo con AC, 61 vs 42%, independientemente de la forma de nacimiento (p< 0.05). El AC fue la única variable que influyó para que se diera LHE. Conclusiones. El AC madre-hijo favorece la LHE en el primer mes posnacimiento.

Abstract: objective. to analyze perinatal births and deaths recording at the mexican institute of social security (miss), and to evaluate the correct classification of perinatal deaths. material and methods. from january to march 2000, data were collected from the 37 miss districts on the total number of births and deaths occurring during 1999, deaths occurring before the seventh day of life, and gestational age and weight at birth. early neonatal and infant mortality rates were analyzed including or separating newborns with <1 000 g and <28 weeks of gestational age. results. during 1999 there were 634 892 live births -whose gestational age and birth weight are unknown- and 3 984 stillbirths 328 gestation weeks. there were 4 556 newborns who died before the seventh day of extrauterine life; 1 385 of them (30.4%) weighed less than 1 000 g and had a gestational age <28 weeks. the analysis of mortality with and without these newborns shows a decrease of two points in early neonatal and infant mortality rates. conclusions. this study shows that classification and reporting of perinatal mortality are inappropriate. a proposal is made to develop information systems that include weight and gestational age of all births. a new perinatal death certificate replacing current fetal and general death certificates would allow proper mortality classification and comparisons between countries.the english version of this paper is available at: http://www.insp.mx/salud/index.html
Propuesta de un certificado de defunción para mejorar el registro y reporte de la muerte en el periodo perinatal

Salud Pública de México , 2001,
Abstract: Objetivo. Analizar la forma en que se registran los nacimientos y la muerte en el periodo perinatal, en el Instituto Mexicano del Seguro Social (IMSS), y documentar si el registro de la muerte, en este periodo, es adecuado. Material y métodos. Entre enero y marzo de 2000, se aplicó una encuesta en las 37 delegaciones del IMSS, para conocer, del a o 1999, el total de nacimientos vivos y muertos, las defunciones ocurridas antes del séptimo día, considerando su edad gestacional y peso al nacimiento. Con estos datos se analizó la mortalidad hebdomadal e infantil y se calcularon las tasas correspondientes, incluyendo o desagregando a los ni os con <1 000 g y <28 semanas de gestación. Resultados. Durante 1999 nacieron vivos en el IMSS 634 892 ni os cuyo peso y edad gestacional se desconocen, y muertos 3 984 ni os con > o = 28 semanas de gestación. Antes de la primera semana de vida extrauterina fallecieron 4 556 ni os, de los cuales 1 385 (30.4%) pesaron <1 000 g y tuvieron <28 semanas de gestación. Al analizar la mortalidad con o sin estos ni os, hubo un descenso de más de dos puntos de tasa en la mortalidad hebdomadal e infantil. Conclusiones. En este trabajo se muestra que la forma como actualmente se clasifica y reporta la muerte de los ni os, en el periodo perinatal, es inadecuada. Se propone crear sistemas de información que permitan conocer el peso y la edad gestacional de todos los nacimientos, así como un nuevo certificado de defunción para el registro de la muerte, en este periodo, que incluya dicha información; éste sustituiría a los certificados de defunción fetal y general actuales y permitiría elaborar reportes comparables con otros países.

Abstract: Objetivo. Identificar las creencias y conocimientos de un grupo de médicos rurales sobre el manejo de alimentación en los casos de diarrea aguda de los menores de cinco a os y compararlos con la recomendación de la Organización Mundial de la Salud (OMS). Material y métodos. Se realizó un estudio de antropología cognitiva con los 10 médicos que brindan atención a la población infantil en el Hospital Rural del IMSS-Solidaridad de San Juanito, Bocoyna, Chihuahua, México, de julio a diciembre de 1998. Se trianguló la información obtenida por las técnicas de grupos focales, vi etas, listado libre, sorteo de montones y cuestionario semiestructurado. Resultados. Los médicos reconocieron el impacto negativo de la diarrea sobre el estado nutricio del ni o, pero no todos evaluaron su estado de nutrición. Como tratamientos predominaron los antimicrobianos, el manejo con líquidos y las recomendaciones sobre alimentación. De éstas, las más consistentes fueron la lactancia materna, la alimentación tardía y la dieta "escalonada". Conclusiones. La información obtenida contrasta con la recomendación de la OMS, en especial con la de alimentación sostenida.

Abstract: this review addresses infant nutrition during the first year of life considering breastfeeding and complementary feeding as its 2 main components. we discuss the benefits that exclusive breastfeeding gives to children, considering the 6th month as the recommended cut off point to initiate complementary feeding. complementary foods for infants older than 6 months are necessary to maintain infant growth, prevent stunting, and iron deficiency anemia. it is important to consider that these foods should be given according with the culture in which the infant belongs. we discuss several aspects to consider before and throughout the process of complementary feeding. before the onset of complementary feeding, it is important to know the motives; the allergic or intolerance food background; the state of the infant's nutritional status and the mother's knowledge of hygiene in food preparation. in the complementary food process, which lasts about 6 months, it is important to consider several practical, nutritious and non nutritious aspects. among the practical aspects it is important to consider factors such as food consistency, size of the portion, food energetic density and the frequency of exchange and combination of different meals. the nutritious topic that must be highlighted is the correct selection of staple foods with the best source of proteins and iron, such as eggs, fish, red meats or legumes. finally, the important non nutritional aspects to consider are the respect of the infant hunger/satiety cycle, the support of the baby's feeding and the encouragement of and appropriate affectionate environment.

Abstract: A cross sectional study was conducted in 190 school-age children classified as obese and 196 classified as eutrophic. Adiponectin, glucose, insulin, high density lipoprotein cholesterol (HDL-C) and triglycerides were determined from a fasting blood sample. Height, weight, waist circumference, systolic and diastolic blood pressures (BP) were measured; MetS was evaluated with the IDF definition. The study groups were divided according to tertiles of adiponectin, using the higher concentration as a reference. Linear regression analysis was used to assess the association between adiponectin and components of the MetS. Finally, stepwise forward multiple logistic regression analysis controlling for age, gender, basal HOMA-IR values and BMI was performed to determine the odds ratio of developing MetS according to adiponectin tertiles.Anthropometric and metabolic measurements were statistically different between eutrophic and obese children with and without MetS (P <0.001). The prevalence of MetS in obese populations was 13%. Adiponectin concentrations were 15.5?±?6.1, 12.0?±?4.8, 12.4?±?4.9 and 9.4?±?2.8 μg/mL for eutrophic and obese subjects, obese without MetS, and obese with MetS, respectively (P <0.001). Obese children with low values of adiponectin exhibited a higher frequency of MetS components: abdominal obesity, 49%; high systolic BP, 3%; high diastolic BP, 2%; impaired fasting glucose, 17%; hypertriglyceridemia, 31%; and low HDL-C values, 42%. Adjusted odds ratio of presenting MetS according to adiponectin categories was 10.9 (95% CI 2.05; 48.16) when the first tertile was compared with the third.In this sample of eutrophic and obese Mexican children we found that adiponectin concentrations and MetS components have an inversely proportional relationship, which supports the idea that this hormone could be a biomarker for identifying individuals with risk of developing MetS.During the last three decades, obesity has emerged worldwide as an epidemic affecting all age

Abstract: An analytical, cross-sectional and population-based study was performed in forty-four public primary schools in Campeche City, Mexico. A total of 466 obese children and adolescents between 11-13 years of age were recruited. Fasting glucose and insulin concentrations, high density lipoprotein cholesterol, triglycerides, waist circumference, systolic and diastolic blood pressures were measured; insulin resistance and metabolic syndrome were also evaluated.Out of the total population studied, 69% presented low values of high density lipoprotein cholesterol, 49% suffered from abdominal obesity, 29% had hypertriglyceridemia, 8% presented high systolic and 13% high diastolic blood pressure, 4% showed impaired fasting glucose, 51% presented insulin resistance and 20% metabolic syndrome. In spite of being obese, 13% of the investigated population did not present any metabolic disorder. For each one of the components of the metabolic syndrome, when insulin resistance increased so did odds ratios as cardiometabolic risk factors.Regardless of age and gender an increased degree of insulin resistance is associated with a higher prevalence of disorders in each of the components of the metabolic syndrome and with a heightened risk of suffering metabolic syndrome among obese children and adolescents.The World Health Organization recognizes overweight and obesity in children and adolescents as worldwide public health problems. Mexico is one of the countries which suffer most from these.Indeed, according to Mexican National Health and Nutrition Surveys, in 1999 [1] the combined prevalence of overweight and obesity in school-age children was 18.6%; by 2006, such prevalence had increased to 26%, which represents an average increase of 1.1 percentage points per year [2].Insulin resistance (IR) is the primary metabolic disorder associated with obesity and is defined as a diminished ability of insulin to stimulate glucose uptake by skeletal muscle and adipose tissue, in addition to reduci

Abstract: A nationwide survey was conducted with a representative sample of children younger than 2 years of age, beneficiaries, and users of health care services provided by IMSS through its regular regimen (located in urban populations) and its Oportunidades program (services offered in rural areas). A subsample of 4,955 clinically healthy children was studied to determine their micronutrient status. A venous blood sample was drawn to determine hemoglobin, serum ferritin, percent of transferrin saturation, zinc, and folic acid. Descriptive statistics include point estimates and 95% confidence intervals for the sample and projections for the larger population from which the sample was drawn.Twenty percent of children younger than 2 years of age had anemia, and 27.8% (rural) to 32.6% (urban) had iron deficiency; more than 50% of anemia was not associated with low ferritin concentrations. Iron stores were more depleted as age increased. Low serum zinc and folic acid deficiencies were 28% and 10%, respectively, in the urban areas, and 13% and 8%, respectively, in rural areas. The prevalence of simultaneous iron and zinc deficiencies was 9.2% and 2.7% in urban and rural areas. Children with anemia have higher percentages of folic acid deficiency than children with normal iron status.Iron and zinc deficiencies constitute the principal micronutrient deficiencies in Mexican children younger than 2 years old who use the health care services provided by IMSS. Anemia not associated with low ferritin values was more prevalent than iron-deficiency anemia. The presence of micronutrient deficiencies at this early age calls for effective preventive public nutrition programs to address them.The first 2 years of life are crucial for children's present and future health and nutritional status and, more specifically, for their mental, physical, and emotional development. In the last decade, micronutrient deficiencies have received much attention as it has been demonstrated that even subclinica
