This study focused on the under-five population of the Alto Xingu region in Brazil, with the following objectives: (1) to evaluate height and weight increment from the first through the fourth years of life and (2) to compare nutritional status in 1980 and 1992. Height and weight increases were evaluated in 81 children. Weight and height were measured in 264 children evaluated in 1980 and in 172 in 1992 (< 10 years of age). Median Z-scores in the first and fourth years of life, respectively, showed: (1) a decrease in weight-for-age, (-0.12 in the first year and -0.51 in the fourth year of life; p = 0.002); (2) a decrease in weight-for-height (+1.31 and +0.08; p < 0.001); (3) an increase in height-for-age (-1.50 and -0.94; p < 0.001). Median Z-scores in 1980 and 1992 showed: (1) no change in weight-for-age (-0.61 in 1980 and -0.62 in 1992; p = 0.90); (2) no change in weight-for-height (+0.27 and +0.34; p = 0.10); and (3) a decrease in height-for-age (-1.04 and -1.22; p = 0.02). Height-for-age increased and weight-for-height decreased between the first and fourth years of life. A decrease in height-for-age was observed from 1980 to 1992, demonstrating the importance of nutritional surveillance among the population of the Alto Xingu.
