Our objective was to evaluate disordered eating and associated factors in university students in the early period of the COVID-19 pandemic in Brazil. This is an analytical cross-sectional observational study, and data collection took place between May and June 2020, using an online semi-structured questionnaire. In total, 936 students were evaluated. Present signs/symptoms of the flu syndrome (OR = 1.605), negative mood changes (OR = 1.628), weight gain (OR = 1.739), obesity (OR = 3.089), follow fitness/health profile on social media (OR = 2.050), having inadequate body perception (OR = 2.416), and body dissatisfaction (OR = 2.612) increased the chances of presenting a higher score on the disordered eating scale.
