Abstract Poor self-management contributes to insufficient glycemic control in adolescents with type 1 diabetes (T1DM). We assessed the effects on glycemic control of adherence to self-measurement of blood glucose (SMBG) and insulin boluses in 90 adolescents with T1DM on insulin pump therapy over a 2-month period. We compared the number of insulin boluses and SMBGs around main meals to the “gold standard” of optimal diabetes management (SMBGs and a bolus before each main meal and SMBG before bedtime). The mean (95% CI) HbA1c levels were 2.9(1.7 to 4.0) mmol/mol lower for every additional insulin bolus and 3.1(1.6 to 4.5) mmol/mol lower for every additional SMBG. Patients performing SMBG and bolusing around each main meal had considerably lower HbA1c levels than those unable to do (95% CI for difference 3.5 to 13.4 mmol/mol(4.3 to 10.4 mmol/mol) and 6.6 to 16.5 mmol/mol(11.5 to 20.1 mmol/mol) respectively). For each additional mealtime bolus/day, the odds ratio of achieving target HbA1c levels of <58 mmol/mol was 6.73(95% CI 2.94–15.38), after adjustment for gender, age, diabetes duration, and affective responses to SMBG in a multiple logistic regression model. Conclusion: Glycemic control in adolescents with T1DM on insulin pump therapy is strongly dependent on adherence to insulin boluses around mealtimes. Results In a linear regression model, the 59 patients (65.6%) who bolused around every main meal according to the gold standard had considerably lower HbA1c levels than the 31 patients (34.4%) who were unable to do so (estimated mean difference 11.6, 95% CI 6.6 to 16.5 mmol/mol). This association remained unchanged after adjustment for age, sex, diabetes duration, and affective responses to SMBG in a multiple regression model. This beneficial effect of mealtime bolusing was strongest for the evening meal insulin bolus: administration of an insulin bolus at every evening meal was associated with an estimated mean (95% CI) HbA1c decrease of 43.2 (21.6 to 64.7) mmol/mol compared to children who did not perform evening mealtime bolusing. The 42 patients (47%) who recorded a glucose measurement before every mealtime had significantly lower HbA1c values (mean difference 8.5, 95% CI 3.5 to 13.4 mmol/mol) (8.5, 95% CI 4.9 to 12.2 mmol/mol) than those who failed to do so. A similar effect was found in patients who recorded an SMBG before sleep compared to those who did not (mean difference in HbA1c 8.8, 95% CI 3.7 to 13.9 mmol/mol) (7.3, 95% CI 4.3 to 10.4 mmol/mol).
