Obesity in pediatric type 1 diabetes: an underestimated health problem
Authors' conclusion
Nearly one-third of youth with T1D in this cohort had overweight or obesity. Higher weight-adjusted insulin requirements may reflect increased insulin resistance in this population.
Study context
- Population
- Youth with T1D enrolled in the Accurate Diagnosis in Diabetes for Appropriate Management (ADDAM) Biobank, Montreal Children's Hospital
- Participants
- 352 participants
- Outcome
- Prevalence of overweight/obesity (BMI ≥ 85th percentile for age and sex)
Methodological detailsmulti-ethnic cohort, single-centre
- Multi-ethnic cohort
- Single-centre
Main finding
As reported in the abstract
BMI category
BMI < 85th percentile
70.5%
BMI ≥ 85th percentile (overweight/obesity)
29.5%
Obesity (BMI > 95th percentile)
10.7%
Observational data: associations, not effects.
Further findings
Associations with weight-adjusted total daily insulin dose (logistic regression)
- Restricted to participants with obesity: association no longer significant after multivariable adjustment
- P = 0.06
- Higher weight-adjusted total daily insulin dose independently associated with BMI ≥ 85th percentile
