Abstract

Objetivo. Estimar el estado nutricional de yodo en mujeres en edad fértil y evaluar la ingesta de sal adecuadamente yodada en sus hogares en el Perú. Materiales y métodos. Estudio transversal realizado con un muestreo probabilístico multietápico por conglomerados que incluyó 1573 hogares y 2048 mujeres en edad fértil, distribuidas en cinco dominios (Lima, resto de costa, sierra rural, sierra urbana y selva). Se evaluó el uso de sal yodada en hogares y el yodo urinario en mujeres en edad fértil. Resultados. El 97,5% (IC95%: 96,7 - 98,5%) de hogares peruanos consumen sal yodada, siendo menor en sierra rural (95%) y mayor en Lima metropolitana (100%). La mediana de yoduria nacional fue de 266 &#956;g/L, siendo menores en la selva (206 &#956;g/L) y mayores en el resto de costa (302 &#956;g/L), estos valores se encuentran por encima del l&#957;mite recomendado por la Organizaci&#963;n Mundial de la Salud en todos los dominios (mediana mayor a 200 &#956;g/L), valor que asegura un control de des&#963;rdenes por deficiencia de yodo (DDI). Conclusiones. En control de los DDI por el consumo de sal yodado es bueno, se debe continuar con la vigilancia de la presencia de yodo en la sal, particularmente en las &#945;reas con menor acceso.<br>Objective. To estimate the iodine nutritional status in women of childbearing age and to evaluate the intake of salt adequately iodized in their households in Peru. Materials and methods. Cross-sectional study performed with a multistage, probabilistic, cluster sampling that included 1573 households and 2048 women in childbearing age, distributed in five domains (Lima, rest of the coast, rural highlands and jungle area). The use of iodized salt was evaluated in the households and the urinary iodine was evaluated in the childbearing age women. Results. 97.5% (95%CI. 96.7-98.5%) of peruvian households have iodized salt consumption, being it lower in the rural highland (95%) and higher in Lima (100%). The national mean of urinary iodine was 266 &#956;g/L, being it lower in the jungle areas (206 &#956;g/L) and higher in the rest of the coast (302 &#956;g/L), these values are above the level recommended by the World Health Organization in all domains (average higher than 200 &#956;g/L), value that ensures control over the iodine deficiency disorders (IDD). Conclusions. Control of IDD associated with iodized salt consumption is good, and monitoring of the presence of iodine in salt, particularly in the areas with lowest access, should continue
