Anthropometric evaluation of indigenous Brazilian children under 60 months of age using NCHS/1977 and WHO/2005 growth curves. J. Pediatr. (Rio J.) [online]. 2009, vol.85, n.2, pp.117-121.

OBJECTIVES: To perform a comparative analysis of anthropometric data from Suruí, Xavánte and Wari' indigenous children under 60 months of age using the NCHS/1977 and the WHO/2005 growth curves. METHODS: Anthropometric measurements followed standard procedures and the data obtained were converted into z scores using the Epi-Info (Version 3.4) and WHO-Anthro (Version Beta) softwares. The indices height/age (H/A), weight/age (W/A) and weight/height (W/H) were descriptors of nutritional status for all children under 60 months of age, as well as the body mass index (BMI) for children 24-59 months old. RESULTS: The frequencies of Suruí children < -2 z scores for H/A were 31.4 (NCHS/1977) and 38.6% (WHO/2005); Xavánte 30.9 and 42.3%; Wari' 61.7 and 68.3%. The frequencies of Suruí children < -2 z scores for W/A were 12.4 (NCHS/1977) and 8.5% (WHO/2005); Xavánte 16.5 and 11.6%; Wari' 51.7 and 45.0%. None of the Suruí children were < -2 z scores for W/H (NCHS/1977 and WHO/2005); the frequencies of Xavánte children were 1.7 and 3.3% and Wari' 1.7 and 0.0%. The frequencies of Suruí children > 2 z scores for W/H were 3.9 (NCHS/1977) and 3.9% (WHO/2005); Xavánte 0.0 and 0.8%; Wari' 0.0 and 0.0%. The frequency of Suruí children aged 24-59 months > 2 z scores for BMI was 5.4% (WHO/2005); Xavánte 9.5%; and Wari' 0.0%. CONCLUSIONS: Our findings revealed important differences in the results from nutritional assessment, according to the set of growth curves used; however, the use of both growth curves revealed a high prevalence of malnutrition. Therefore, future studies with indigenous populations should present their results using two sets of growth curves to allow consistent comparison.
