Changes in body weight during the COVID-19 pandemic in the NutriNet Brazil cohort

Abstract

This study describes changes in body weight among participants of the NutriNet Brazil cohort (n=14,529) during the COVID-19 pandemic. Body weight data reported in the period before the start of the pandemic (26/01-18/03/2020) and about 6 months after (14/09-19/10/2020) were analyzed. Weight gain ≥2 kg reached 19.7% of the participants and was inversely associated with age and directly associated with lower education and baseline overweight status. Weight loss ≥2kg reached 15.2% of the participants and was inversely associated with age and directly associated with higher education and baseline overweight status.
