The impact of COVID-19 in children and adolescents with obesity in Brazil

ABSTRACT

ABSTRACT Objective: The primary goal of the study was to evaluate weight gain in children and adolescents with obesity during the COVID-19 pandemic period, and compare it with the period before the pandemic. Subjects and methods: The sample comprised 68 children with obesity aged between 7 and 18 years, 30 (44.1%) boys and 38 (55.9%) girls, who were attended at the pediatric endocrinology clinic of the Irmandade da Santa Casa de Misericórdia de São Paulo, SP, Brazil. Weight gain in the sample in the pre-lockdown period (December 2, 2018 to March 11, 2020) was compared with that in the lockdown period (March 11, 2020 to February 21, 2021). Results: Approximately one year before the start of the pandemic period, the mean (SD) chronological age was 10.1 years old (± 2.4), and an average weight gain of 4.4 kg (± 4.8) was observed during the pre-lockdown period described. One year after the start of the pandemic, mean (SD) chronological age was 11.8 years old (± 2.4), and an average weight gain of 8.5 kg (± 7.6) was observed in the lockdown period described. When we compared the weight gain in the two periods, it was higher in the pandemic period, both in girls and boys (p = 0.013 and 0.035, respectively). Conclusion: The results of the study show that the period of social isolation adopted to mitigate the COVID-19 pandemic was associated with increased weight gain in the studied population, probably due to a reduction in physical activities and an increase in energy consumption.
