We apologize for a mistake regarding the origin of the database used for the sections named “Indigenous population from Brazil”. The quoted references (Lebel et al., 1996, 1998; Dolbec et al., 2001) in the Methodology and Results sections and in the legend to Figure 4 are not adequate. The subjects in these examples were not native, but rather from a Riparian population of the Brazilian Amazone. These unpublished data were collected in 2000 by Carlos JS Passos from CINBIOSE, University of Quebec in Montreal, in the context of the CARUSO project.

We add the following to the acknowledgement section:

For graciously providing their database, we wish to thank: (1) Carlos JS Passos and Donna Mergler from CINBIOSE at the University of Quebec in Montreal, (2) Laurie Chan from the Centre for Indigenous Peoples' Nutrition and Environment at McGill University and (3) Pierre Ayotte from the Institut national de santé publique du Québec.

We apologize for this mistake.
