Ethics approval and consent to participate

: Each individual that entered the clinic was approached for participation by the researcher, who verified eligibility and provided an overview of the study. Due to low literacy levels, consent to participate was obtained from each participant by verbally reviewing the consent form, providing all pertinent information to the subject and allowing the subject the opportunity to ask questions. Participants were required to sign (or print) their names at the bottom of the consent form before beginning the survey, and were provided with a copy of the consent form if requested. The project was reviewed and approved by the Emory University Institutional Review Board (Atlanta, GA, USA) and the Municipality of Mauá (São Paulo, SP, Brazil); this approval included the verbal consent process.
