Abstract

This study describes body weight changes among participants of the NutriNet Brasil cohort (n = 14,259) during the covid-19 pandemic. We analyzed data reported before the pandemic onset (01/26/2020 to 03/18/2020) and about six months after (09/14/2020 to 10/19/2020). Our results show that 19.7% of the participants gained ≥ 2 kg. Weight gain was directly associated with male gender, lower education, and previous presence of overweight, and inversely associated with age. In turn, 15.2% lost ≥ 2kg, being directly associated with male gender and previous presence of overweight and inversely associated with age.

RESUMO: Este estudo descreve modificações no peso corporal de participantes da coorte NutriNet Brasil (n = 14.259) ocorridas durante a pandemia de covid-19. Foram analisados dados informados em período anterior ao início da pandemia (26/01/2020 a 18/03/2020) e cerca de 6 meses após (14/09/2020 a 19/10/2020). O ganho de peso ≥ 2 kg alcançou 19,7% dos participantes, mostrando-se diretamente associado ao sexo masculino, à menor escolaridade e à presença prévia de excesso de peso, sendo inversamente associado à idade. A perda de peso ≥ 2kg alcançou 15,2% dos participantes, mostrando-se diretamente associada ao sexo masculino e à presença prévia de excesso de peso, sendo inversamente associada à idade.
