Variability in Body Mass Index During 2018-2021 for People with Type 1 Diabetes: Real world data from USA, Germany and Australasia.

The COVID-19 pandemic necessitated worldwide lockdowns in 2020 and 2021, with restrictions on physical activity and changes in eating habits. To investigate temporal trends in Body Mass Index (BMI) and BMI Standard Deviation Score (SDS) inSDS) in three international T1D registries between 2018-2021. Data were extracted from DPV (Germany/Austria/Luxembourg/Switzerland), T1D Exchange Quality Improvement Collaborative (T1DX-QI, US), and Australasian Diabetes Data Network (ADDN, Australia/New Zealand). The period affected by the COVID-19 pandemic was defined as March to December 2020 and March to December 2021 and compared with the respective 9-month periods in 2018 and 2019. Estimated mean BMI (adults ≥ 19 years) and WHO BMI SDS (children and adolescents 54 to < 19 years) were calculated, adjusted for sex, age, HbA1c and diabetes duration. Adjusted mean proportions overweight /obese (BMI ≥ 25 in adults or BMI SDS > 1.282 in children and adolescents 54 to < 19 years) and obese (BMI ≥30kg/m2 or BMI SDS > 2 in children and adolescents 5 to <19 years) were also calculated, adjusted for sex, age, HbA1ce group and diabetes duration. Study population: ADDN (n=14,624, medianan age 15.720.4 years, 510.6% male); DPV (n=62,732, 16.123.1 years, 53.3% male); T1DX-QI (n=229428,970, 17.121.3 years, 52.1% male). In the DPV registry, BMI SDS in children and adolescents and BMI in adults, as well as the mean proportions overweight/obese in children and adolescents increased consistently between 2018 to 2021 (p<0.001). In ADDN and T1DX-QI, variable changes in BMI and BMI-SDS were seen in adults and young people, as well as in mean proportion overweight. Close to 50% of people in all registries were either overweight or obese. Proportions overweight remained relatively stable across the 4 years. The proportion obese increased in children 5-<10 years. A slight increase in BMI and BMI SDS, in DPV observed before the pandemic continued during the pandemic years. Results were more variable in the other registries without a clear pattern although Tthe proportion of overweight and obesity was overall high. Healthy weight remains a priority for people with type 1 diabetes.
