Relationship between Glycemic Control and Blood Pressure in Pediatric Patients with Type 1 Diabetes Mellitus at Dr. M. Djamil Hospital Padang

Background: The prevalence of type 1 diabetes mellitus (T1DM) in children is increasing globally, with hypertension as a common comorbidity. Research examining the relationship between glycemic control and blood pressure in pediatric T1DM remains limited. Methods: A cross-sectional study was conducted at DR. M. Djamil Hospital Padang from December 2024 to November 2025. Sixty T1DM patients aged 6 months to 18 years were included through consecutive sampling. Glycemic control was assessed using HbA1c levels, and blood pressure was measured using a digital sphygmomanometer. Data were analyzed using Chi-Square test with significance level p7.0%), while 21.7% achieved target control. Blood pressure distribution showed 55.0% normotensive, 11.7% elevated blood pressure, 20.0% stage 1 hypertension, and 13.3% stage 2 hypertension. Chi-Square analysis revealed no significant relationship between glycemic control and blood pressure (p=0.190). Conclusion: No significant association was found between glycemic control and blood pressure in pediatric T1DM patients. However, the high prevalence of both poor glycemic control and hypertension emphasizes the need for education and blood pressure screening.
