Variability in Body Mass Index during 2018–2021 for People with Type 1 Diabetes: Real World Data from the USA, Germany, and Australasia
Authors' conclusion
A slight increase in BMI and BMI SDS observed before the pandemic continued during the pandemic years. The proportion of overweight and obesity was overall high. Healthy weight remains a priority for people with T1D.
Study context
- Population
- People with T1D in three international registries (USA, Germany/Austria/Luxembourg/Switzerland, Australia/New Zealand), 2018–2021; adults ≥19 years and children and adolescents 5 to <19 years
- Participants
- 14,624 / 62,732 / 22,942
- Exposure
- COVID-19 pandemic periods vs respective 9-month periods in 2018 and 2019
- Australasian Diabetes Data Network (ADDN)n = 14,624
- DPVn = 62,732
- T1DX-QIn = 22,942
- Outcome
- Temporal trends in BMI (adults) and WHO BMI SDS (children and adolescents)
- Follow-up
- 2018–2021
Methodological detailsthree international T1D registries, multinational, adjusted for sex, age, HbA1c and diabetes duration
- Three international T1D registries
- Multinational
- Adjusted for sex, age, HbA1c and diabetes duration
Main finding
As reported in the abstract
BMI and BMI SDS trends
- DPV: Body mass index (BMI) Standard Deviation Score (SDS) in children and adolescents and BMI in adults increased consistently between 2018 and 2021
- p < 0.001
Observational data: associations, not effects.
Further findings
- People either overweight or obese in all registries
- Close to 50%
- Proportions overweight remained relatively stable across the 4 years
- Proportion of obesity increased in children 5 to <10 years
