Main outcome measures
After agreeing to participate, students completed and signed
an informed consent statement. The students’ participation
consisted of individually completing a structured research
questionnaire with 98 closed questions. This survey assesses
the lifestyle of Brazilian college students. The content of this
questionnaire is based on the World Health Organization’s
(WHO’s) research instrument, which was previously adapted
by Andrade et al.17 and Stempliuk et al.18 for use with Brazilian
college students. On average, the questionnaire required 50
minutes to complete. After finishing the questionnaire, the
students deposited it along with the consent form in separate
urns, thereby making identification of the answers impossible and guaranteeing confidentiality.
