Introduction
Persistent hyperglycemia during the progression of type 1 diabetes mellitus (T1DM) can impact growth velocity. Another factor that may be relevant for better glycemic control is nutritional status.
Objectives
To evaluate growth and nutritional status in pediatric patients with T1DM at diagnosis and during follow-up.
Methods
An observational and retrospective study was conducted at a tertiary hospital in Brazil, with data collection from March 2025 to April 2026. Patients diagnosed with T1DM and followed between 2004 and 2026 were included. Excluding those with pathologies impacting growth. Data were obtained from medical records. Variables analyzed were BMI and height at diagnosis and at the most recent visit. Anthropometric data were expressed as Z-scores using World Health Organization(WHO) growth charts. Statistical analysis was performed using Epi Info™, with descriptive measures and group comparisons according to disease duration(first year, 2–5, 6–10, and >10 years), considering p<0.05 as significant.
Results
At diagnosis, BMI Z-scores were available for 54patients, with a mean of 0.0(SD±1.43); 2were underweight, and 12overweight. Mean height-for-age Z-score was 0.33(SD±1.04). At the last visit, 228patients(mean age 12.85years, SD±4.01) had a mean height Z-score of -0.29(SD±1.13). Among 71patients older than 15years, mean height Z-score was -0.57(SD±1.06). BMI at the last visit showed a mean Z-score of 0.23(SD±1.12); 6were underweight, and 60overweight. No significant differences in BMI or height were observed across disease duration groups(p>0.05). Overweight prevalence increased from22%at diagnosis to26%during follow-up.
Conclusions
Patients with T1DM maintained height within normal ranges, with no significant impact of disease duration on growth or BMI. The increasing prevalence of overweight highlights the importance of nutritional guidance and physical activity, as excess weight may negatively affect metabolic control.
