Many diabetic clinics in Sweden recommend four self monitoring of blood glucose (SMBG) per day for CSII treated adolescents, however it is common that CSII treated adolescents with type 1 diabetes perform fewer SMBG than recommended.
Objectives: To compare age, diabetes duration, HbA1c value, frequency of daily bolus doses and health related quality of life (HRQOL) measured with the “Disabkids” questionnaire, between CSII treated adolescents who perform less than four SMBG per day and CSII treated adolescents who perform four or more.
Methods: Data were obtained from 91 CSII treated adolescents (aged 12-18), who were regularly attending four different paediatric diabetes clinics in Sweden, all recommending four SMBG per day. Unpaired t-test was used to compare the group who took < 4 SMBG/day with the group who took > 4 SMBG/day. Nominal logistic regression analysis was used to compare the two groups.
Results: The mean frequency of SMBG/day was 3.2. Forty-four % (40/91) of the adolescents performed four or more SMBG/day. The adolescents who performed the recommended frequency of SMBG were younger, had shorter diabetes duration, had lower HbA1c, took more daily bolus doses and perceived less impact of the medical treatment. There were no differences in general HRQOL between the two groups. Nominal logistic regression analysis showed that of these factors only HbA1c was independently associated to > 4 SMBG/day (p<0.001).
Conclusion: Fifty-sex % of the adolescents performed fewer SMBG than recommended. The frequency of SMBG was associated with the metabolic control. The diabetes teams need new strategies to motivate adolescents to perform more SMBG.
