Weight gain in type 1 diabetes during the SARS-CoV-2 pandemic. Does lockdown affect the metabolic control of pediatric patients?
Abstract
Background and aimsDue to the severe acute respiratory syndrome coronavirus 2 pandemic, governments of many countries decided to implement lockdowns, which included school closures. This major lifestyle change also applied to people with diabetes. The aim of this paper was to analyze how the COVID-19 pandemic and related restrictions influenced the metabolic compensation of diabetes in the pediatric population.MethodsPatients with type 1 diabetes (T1D), treated by one therapeutic team, who in 2020 and 2021 paid at least two in-person visits in the outpatient clinic, were included in the study. The time in range (TIR) and HbA1c, as well as the total daily dose (TDD) of insulin and BMI from the visit before the announcement of the pandemic restrictions (March 2020) and during the lockdown (second visit after 6 months) and within the period of loosened restrictions (two visits in 2021) were analyzed.ResultsA total of 185 patients with T1D were included in the study (96 boys), aged 2–18 years (11.5 ± 3.5); 135 of them (72.9%) use CSII and 142 (76.8%) use CGM or FGM. During the first months of the studied period, despite comparable (p>0.05) TIR (57.5 ± 21.4% vs. 59.9 ± 20.5%), improvement of HbA1c was noticed (7.9 ± 1.6% vs. 7.5 ± 1.4%, p=0.0336), whereas in the following months, both HbA1c and TIR were comparable. Also, the TDD increased significantly (from 37.3 ± 18.9 units/day on the first visit up to 46.8 ± 22.7 units/day on the last visit, p=0.0003); however, TDD/kg remained constant (p>0.05) (0.8 ± 0.2 units/kg/day vs. 0.8 ± 0.3 units/kg/day) possibly due to an increased BMI (19.1 ± 3.7 kg/m2vs. 20.9 ± 4.1 kg/m2, p=0.0001). The percentage of basal insulin in the TDD remained stable (p>0.05) (39.7 ± 11.3% vs. 39.3 ± 13.6%). Furthermore, a significant (p=0.0001) change in the BMI percentile was noticed [from 58.9 ± 26.2 percentiles (%iles) before lockdown vs. 64.6 ± 26.0%iles on the second visit]. However, the BMI percentile returned to baseline (58.1 ± 28.4%iles) at the visit at the end of the observation period.ConclusionsThe parameters of metabolic control in pediatric patients with T1D during the pandemic period remained stable; however, weight gain and an increase in daily insulin dose have been observed, possibly due to reduced physical activity.
