Introduction. The human growth and the resulting pattern display a great intra e interpopulation heterogeneity that reflects the health and nutritional state, and indirectly, the quality of life of the populations. The objective of this work was to determine with the LMS method, the weight, height and BMI percentiles of schoolchildren population of San Salvador of Jujuy and to compare them with those of the international reference. Population, material and methods. The data were obtained from all the students of 4 to 16 years of age, of both sexes, evaluated in the Schoolchildren Health Department of Jujuy Province (n=48,384) that cares of children that attend to public and private schools of San Salvador de Jujuy. The W/A, H/A and BMI/ A percentiles were obtained by the maximum penalised likelihood using the LMS method. The statistical and graphical comparisons were settled down with the corresponding percentiles of the NCHS reference, estimated with the same method. Results. In general, the estimated percentiles agree with those of the reference, mainly in the age groups more representative numerically. These coincidences are evident graphically and statistically, since the discrepancies between the estimated and published values varied between 0.05 and 3.7% for the positive values and between -0.46 and -2.24% for the negatives values. Conclusions. The W/A, H/A and BMI/A percentile curves of San Salvador de Jujuy schoolchildren obtained by the LMS method do not differ substantially from those of the reference.
