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.
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).
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.
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).
