    Abstract:
    The purpose of this cross-sectional study was to explore the determinants of hemoglobin A1c (HbA1c) levels in insulin-treated patients with Type 2 diabetes mellitus (T2DM) based on demographic and disease characteristics, self-reported regimen adherence factors (adherence in insulin regimen and self-monitoring of blood glucose), and psychosocial factors (decisional balance for insulin injection, health literacy, self-efficacy for insulin injection, diabetes distress, and empowerment perceptions). Via convenience sampling, 255 insulin-treated patients with T2DM were recruited from two endocrinology clinics in Taiwan. A self-report questionnaire was used to collect demographic and disease characteristics, regimen adherence factors, and psychosocial factors. The first HbA1c level measured after completion of the questionnaire was the dependent variable. The last HbA1c level measured before patients started insulin therapy as well as body mass index (BMI) was collected from medical records. Results indicated that adherence in insulin regimen was relatively good. Regimen adherence factors did not significantly correlate with HbA1c levels, but empowerment perception, decisional balance for insulin injection, health literacy, and diabetes distress did. The hierarchical multiple regression models indicated that BMI, the last HbA1c levels before starting insulin therapy, empowerment perception, and diabetes distress were important determinants of HbA1c levels. Nurses could periodically assess the diabetes distress of insulin-treated patients with T2DM and refer to mental health professionals when needed. Furthermore, applying empowerment approaches such as enhancing self-awareness of improved glycemic control and sharing more decision-making power with insulin-treated patients with T2DM might have benefits for their glycemic control.
