          El objetivo del presente estudio es evaluar el estado nutricional e ingesta de hierro (Fe), zinc (Zn) y cobre (Cu) en mujeres chilenas en edad fértil. Se estudió una muestra de conveniencia de 86 mujeres entre 18 a 48 años de edad de la ciudad de Santiago, Chile. El estado nutricional de Fe se determinó a través de hemoglobina (Hb), volumen corpuscular medio, saturación de transferrina, zinc protoporfirina, ferritina sérica (FS), Zn y Cu séricos. La ingesta dietética fue evaluada con una encuesta de frecuencia de consumo. Un 4,7% de las mujeres presentó anemia por deficiencia de Fe, 21% deficiencia de Fe sin anemia, 26% depósitos depletados de Fe y un 48,3% estado nutricional normal de Fe. Las mujeres obesas presentaron mayores niveles de FS (p<0,01) al comparar con mujeres con peso normal. Además, presentaron niveles más altos de Hb (p<0,05) al comparar con mujeres con estado nutricional normal y sobrepeso. El 3,5% y 2,3% de las mujeres presentó deficiencia de Zn y Cu, respectivamente. El 95%, 94% y 99% cumplió el EAR para Fe, Zn y Cu, respectivamente. No se encontraron diferencias significativas en la ingesta de micronutrientes entre las mujeres al comparar por estado nutricional. En conclusión, un alto porcentaje de las mujeres presentó una ingesta adecuada de micronutrientes. Además existe una baja prevalencia de deficiencia de Zn, Cu y anemia. Sin embargo, un 47% presenta deficiencia de Fe en etapas anteriores a la de anemia.

          The aim of the present study was to evaluate anemia, the biochemical status and dietary adequacy of iron (Fe), zinc (Zn) and copper (Cu), in Chilean childbearing age women. We studied a convenience sample of 86 women aged 18 to 48 years from Santiago, Chile. We determined anemia and the micronutrient status through hemoglobin (Hb) mean corpuscular volume, transferrin saturation, zinc protoporphyrin, serum ferritin (SF), serum Zn and Cu. Dietary adequacy was estimated using a food frequency questionnaire. Of all women, 4.7% had Fe deficiency (ID) anemia, 21 % ID without anemia, 26 % depleted Fe stores and 48.3% normal Fe status. Obese women had higher SF (p<0.01) compared with those classified as having normal BMI. Also, showed higher Hb (p<0.05) concentrations compared with overweight and normal weight women. Participants showed 3.5 % and 2.3 % of Zn and Cu deficiency, respectively. Also, 95 %, 94 % and 99 % had adequate intake of Fe, Zn and Cu respectively, according to EAR cut points. There were no significant differences in micronutrients intake across different nutritional status. There was a low prevalence of anemia, Fe, Zn and Cu deficiency. A high percentage of women reached micronutrient adequacy. However, 47% of women had ID without anemia and Fe depleted stores.

          Addressing malnutrition while avoiding obesity: minding the balance.

          Latin America has experienced rapid demographic, epidemiological and nutrition changes that have successfully contributed to decreasing undernutrition, but concomitantly have resulted in an increase of obesity and associated conditions; in this paper we propose that policies to address undernutrition have not adapted at a sufficiently rapid pace to address the emerging challenges. Taking Chile as an example we show that health promotion policies, implemented only when the obesity epidemic was well advanced, have succeeded in establishing effective regulatory frameworks and in implementing national large-scale programs for treatment; however, they have been insufficient in preventing obesity. The main lessons learned are: (1) Failure to monitor existing malnutrition programs for changing needs and true effectiveness can have unintended consequences. (2) Institutions and professionals working in nutrition and health need to assess changing scenarios and redefine their priorities for action accordingly. (3) There is a need to provide updated information to decision makers, program planners and to the population at large on how to promote and achieve healthy food consumption and active living considering local context. Timely policies and interventions to address these issues may contribute to the prevention of the obesity epidemic in transitional countries, particularly among low socioeconomic groups.
