Abstract
Objective: To analyze whether adherence to insulin therapy steps in people with type 1 and 2 diabetes mellitus (DM) is associated with self-efficacy and to estimate the prevalence of lipohypertrophy. Method: This is an analytical cross-sectional study, carried out with people with type 1 or 2 DM using insulin therapy, attended and monitored in a public care center for people with diabetes in Goiás from May to August 2023. Results: The sample consisted of 97 participants. When analyzing adherence to the steps of insulin therapy, it was found that storage, reuse of needles and disposal are the steps that most individuals still perform inappropriately. The rate of adherence to the correct technique was 69,2%. When measuring insulin therapy self-efficacy in people with diabetes, the global average was 1,75 points. Bivariate analysis revealed that being a young adult (p=0,012), having DM1 (p=0,021), not using NPH insulin (p=0,021), using slow-type insulin (p=0,024) and performing skinfold (p=0,033) were associated with better self-efficacy. The prevalence of lipohypertrophy was 7,2% among research participants. Conclusion: The individuals in this research had better self-efficacy skills in preparing and applying insulin, in addition, the prevalence of lipohypertrophy was low in these people. And the worst self-efficacy results are related to a lack of confidence in insulin management.
