dc.descriptionIntroducción: El zinc (Zn) es un micronutriente esencial en el crecimiento celular, la síntesis proteica y la diferenciación celular. La deficiencia de Zn afecta el crecimiento y desarrollo del niño, el metabolismo energético y la respuesta inmune. Objetivo: Examinar los factores asociados a la deficiencia de Zn en una muestra representativa de colombianos niños. Pacientes y métodos: Estudio descriptivo transversal, secundario de la información obtenida en la Encuesta Nacional de la Situación Nutricional 2010 (ENSIN 2010), en 4.279 niños entre 12 y 59 meses. Los niveles plasmáticos de Zn se determinaron por espectrofotometría de absorción atómica, y los factores asociados (sexo, edad, etnia, puntaje de SISBEN, región y área geográfica) se recogieron por encuesta estructurada. Se establecieron asociaciones mediante la construcción de modelos de regresión y factores asociados. Resultados: Se encontró un valor promedio de Zinc de 78,5 µg/dl (IC 95% = 76,7-80,4 µg/dl). El 43,3% (IC 95% 42,2-44,3%) de los niños presentaron niveles de Zn menores a 65 µg/dl. Los niños pertenecientes a grupos étnicos (indígena) o que residen en áreas rurales; presentaron mayor déficit de Zn (56,3% y 47,8%) respectivamente. Los modelos de regresión muestran que; ser indígena (OR 1,76 IC 95% 1,29-2,41); y residir en zonas rurales (OR 1,39 IC 95% 1,16-1,67), se asociaron al déficit de Zn. Conclusiones: La población estudiada presenta una alta prevalencia de déficit de Zn, por lo que se recomienda intervenciones integrales donde estén involucrados el componente nutricional y educativo.spa
dc.description.abstractIntroduction: Zinc (Zn) is an essential micronutrient for cell growth, protein synthesis and cell differentiation. This deficiency affects the growth, development, energy metabolism and immune response in Colombian children’s. Objective: To examine factors associated with Zn deficiency in a representative sample of Colombian children. Patients and methods: A cross-sectional descriptive study was conducted of data from the 2010 National Nutrition Survey of Colombia (ENSIN 2010), in 4.279 children aged between 12-59 months of age. Plasma levels of Zn were determined by atomic absorption spectrophotometry, and associated factors (sex, age, ethnicity, SISBEN score, and geographic region) were collected by structured questionnaire. Associations were established through a multivariable regression model. Results: We found a range of Zn of 78.5 µg/dl, (95% CI 76.7 to 80.4 µg/dl). 43.3% (95% CI 42.2%-44.3%) of children had lower Zn levels to 65 µg/dl. Children belonging to an ethnic groups (indigenous) or residing in rural areas; showed Zn deficiency (56.3% and 47.8%) respectively. Regression models show that to be indigenous (OR 1.76, 95% CI 1.29 to 2.41), and to reside in rural areas (OR 1.39, 95% CI 1.16 to 1.67) were associated with Zn deficiency. Conclusions: The study population shows a high prevalence of Zn deficiency, so it is recommended that comprehensive interventions which are involved nutritional and educational component.spa
