Metabolic and anthropometric profile of Aruak Indians: Mehinaku, Waura and Yawalapiti in the Upper Xingu, Central Brazil, 2000-2002

The objective of this study was to describe the anthropometric and metabolic profile of Aruak Indians (Mehinaku, Waura, and Yawalapiti) in the Upper Xingu, Central Brazil. In July 2000 and October 2002, 201 subjects of both genders and aged : 20 years were submitted to physical (anthropometric and blood pressure measures) and laboratory (fasting blood glucose, serum lipids, and uric acid) examination. As compared to females, males had lower mean skin fold thickness measurements and serum HDL cholesterol, and higher body mass index, arm circumference, systolic and diastolic blood pressure, serum triglycerides, VLDL cholesterol, and uric acid. The prevalence rates for overweight (51.8%), obesity (15%), dyslipidemia (77.1 To), and hypertension (37.7%) were higher among men than women, but prevalence of abdominal obesity (52.1%) was higher among women than men, independently of age and origin. These results corroborate the need to implement measures to control and prevent obesity and other cardiovascular risk factors among these indigenous peoples.
