To investigate the physical growth of Xavante children aged 5-10 years and living at the Sangradouro and são Marcos reservations, state of Mato Grosso, central Brazil. METHODS: A cross-sectional survey was carried out in February 1997 in two native Brazilian Indian schools. Our sample included 233 children. The following data were collected: birth date, sex, weight, height, arm-muscle circumference, and triceps skinfold thickness. Data on height and weight were compared to National Center for Health Statistics (NCHS) growth charts following the recommendation of the World Health Organization. RESULTS: Our results show that 9% of our population sample had height-for-age Z scores <-2. For boys, statistically significant differences (P<0.05) in height-for-age and weight-for-age Z scores were observed between the two communities. Similar differences were not observed for girls. Xavante children are, in average, shorter in height than North-American children. However, for some age groups, the average values of height overlap with those of the Brazilian children investigated by the National Research on Health and Nutrition (PNSN). CONCLUSIONS: The physical growth profile of Xavante children presented important differences when compared to that of a number of other South American native Indian populations. Based on the information collected, we argue that North-American curves can be used to evaluate the nutritional status of Xavante children.
调查居住在巴西中部马托格罗索州桑格拉杜罗和圣马科斯保留地的5至10岁哈万特儿童的身体发育情况。方法：1997年2月在两所巴西本土印第安学校进行了一项横断面调查。我们的样本包括233名儿童。收集了以下数据：出生日期、性别、体重、身高、上臂肌肉周长和三头肌皮褶厚度。按照世界卫生组织的建议，将身高和体重数据与美国国家卫生统计中心（NCHS）的生长图表进行比较。结果：我们的结果显示，我们的人口样本中有9%的年龄别身高Z评分＜-2。对于男孩，在两个社区之间观察到年龄别身高和年龄别体重Z评分存在统计学显著差异（P＜0.05）。女孩未观察到类似差异。哈万特儿童的平均身高低于北美儿童。然而，对于某些年龄组，身高平均值与国家健康与营养研究（PNSN）调查的巴西儿童的身高平均值重叠。结论：与其他一些南美本土印第安人群相比，哈万特儿童的身体发育情况存在重要差异。根据收集到的信息，我们认为北美曲线可用于评估哈万特儿童的营养状况。
