LOPES, Cristiana et al. Knowledge about Carbohydrate Count and metabolic control in patients with Continuous Subcutaneous Insulin Perfusion System. Acta Port Nutr [online]. 2019, n.19, pp.20-23. ISSN 2183-5985.  https://doi.org/10.21011/apn.2019.1904.

The prevalence of type 1 diabetes mellitus has been increasing in recent years. Intensive treatment through Continuous Subcutaneous Insulin Perfusion System is the most physiological method of insulin administration currently available. For this to be effective it is essential to have knowledge about the composition of the food, particularly about its content in carbohydrates. The aim of the present study was to evaluate and characterize metabolic control, to compare it before and after Continuous Subcutaneous Insulin Perfusion System, to evaluate the carbohydrates count knowledge and to relate it to metabolic control. This is an observational, analytical and retrospective study, with a convenience sample of patients consulted between November 2017 and March 2018 at the Garcia de Orta Hospital. The evaluation of metabolic control was performed through HbA1c. In the evaluation of the knowledge about carbohydrates count, an adaptation of the PedCarbQuiz questionnaire was used. Sixty individuals with a mean age of 21.3 ± 14.27 years were evaluated [2-57]. At the Subcutaneous Insulin Perfusion System, placement, only 23.6% of the sample was HbA1c within the recommended values. 3 months after Continuous Subcutaneous Insulin Perfusion System placement there was a substantial decrease in HbA1c, which stabilized after the first 6 months. Regarding the knowledge about carbohydrates count, 78.3% had “very good” level and the remaining “good” level. No significant correlation was detected between HbA1c and carbohydrates counting knowledge. Having more knowledge has not been shown to influence the metabolic control of the sample.
