Declarations

:

: All methods employed in this study were carried out in accordance with relevant guidelines and regulations, mainly the Brazilian National Health Council (CNS) Resolution 466/2012. The authors of this paper had no participation in the data collection, which was carried out by two governmental institutions in Brazil and were made publicly available on the internet. We do not have any access to personal information about the participants, which are kept confidential by Fiocruz. The Brazilian legislation (Resolution 510, of April 7, 2016, from the National Health Council/Health Ministry) establishes that studies that use information with public access will not be registered or evaluated by the Research Ethics Committee. This study fits into that category. The Brazilian National Health Survey (PNS 2013) methodology, including the collection of biomarkers, was approved by the National Commission for Ethics in Research (CONEP: ExternalRef removed) under #10853812.7.0000.0008 [CitationRef removed].
