Fish consumption (Hair Mercury) and nutritional status of Amazonian Amer-Indian Children
Abstract
Fish are abundant and important dietary items for the Amer-Indians, and total hair-Hg (HHg) concentration is a reliable marker of fish consumption. We studied the impact of fish consumption (HHg) on the nutritional status of Indian children of Eastern Amazonia. Weight-for-height Z score (WHZ) was measured, and HHg was determined in 203 children younger than 10 years of age in three villages. There was significantly higher fish consumption in Kayabi children (16.55 microg Hg/g; SD, 11.44) than in children of the Munduruku villages of Missão-Cururu (4.76 microg Hg/g; SD, 2.09) and Kaburua (2.87 microg Hg/g; SD, 2.13). Anthropometric indices showed WHZ means of -0.27, -0.22, and 0.40, respectively, for Kayabi, Missão-Cururu and Kaburua villages. Despite a different pattern of fish-protein consumption between tribes, there was no significant correlation between WHZ and HHg concentrations (r2 = 0.0079; P < 0.2021). Dietary differences among Amazonian tribes can be traced and used in measuring health outcomes. Higher fish consumption, although important for Kayabis, was compensated by other protein sources by the Kaburua villagers.

Fish consumption among Munduruku indigenous people can be considered high, at least three meals per day, varying slightly between different groups.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
