In El Salvador, an important part of children suffer from malnutrition, which in its severe forms and in pre-school age, has an impact on their growth and development. At this age, weight and height increases gradually decrease, however, increases in arm muscle area are moderate but uninterrupted from 18 to 69 months, so the brachial perimeter is a sensitive indicator, and specific in the detection of nutritional changes in the body cornposition in preschool. The objective was to establish the degree of sensitivity and specificity of the brachial perimeter as an indicator of body mass, against the measures Weight / Age, Size / Age and Weight / Size. In this descriptive, cross-sectional, correlational study, 100 children from 72 to 48 months of age were measured, in a simple randomized manner at the Zacarnil National Hospital External Consultation, considering as Study variables: Weight, Height, Brachial Perimeter, Sera, Age. The anthropometric measurement techniques as proposed by the World Health Organization (WHO) are: Anthropometric reference parameter: Score Z. The statistical analysis program Epi-Info 2002 was used; Sensitivity and specificity of the brachial perimeter were calculated against weight / age, height / age and weight / height indicators, correlation coefficient. It was found that 83% of the children were eutrophic according to the Z score of the brachial perimeter and 17% had some degree of malnutrition. The specificity of the brachial perimeter was: 95%, 95.7% and 86.9% when related to weight / age, weight, size and height / age respectively. The sensitivity of the brachial perimeter: 42%, 33% and 12.5%. Erg eutrophic correlation coefficient: brachial perimeter / weight: 0.72. Brachial perimeter / Size was 0.41. And versus Weight / height it was 0.65. Errnutrition correlation coefficient: Brachial perimeter / weight: 0.4. Brachial perimeter / Logging / was —0.2. Words
