The role of depression, stress and self-management behaviors on metabolic control in adults with type 2 diabetes.

摘要

Aims: To (1) determine the contributions of depression, stress and self-management behaviors (e.g., diet, exercise) to metabolic control (hemoglobin A1c, high-density lipoprotein, low-density lipoprotein and triglyceride) and (2) examine the association among depression, stress and self-management behaviors in adults with type 2 diabetes.;Background: Depression and stress are common in patients with diabetes and military families may be under high stress. However, the associations of depression, stress, and self-management behaviors, and their potential contributions to metabolic control in adults with type 2 diabetes have been limited.;Design: A cross-sectional study.;Methods: Adults with type 2 diabetes (N = 150) were recruited from a family medicine clinic in a military setting. Data were collected from September 2012 to April 2013, using validated questionnaires for depression, stress, and self-management behaviors. Laboratory data were collected as measures of metabolic control. Data were analyzed using a general linear model and Pearson's correlation.;Results: Depression, stress and self-management behaviors did not have significant contributions to metabolic biomarkers. However, depression was positively associated with stress (r = 0.72, p < 0.001), whereas self-management behaviors were negatively associated with depression (r = -0.22, p = 0.006) and stress (r = -0.22, p = 0.006).;Conclusion: Although there were significant associations among depression, stress and self-management behaviors, these factors failed to influence any metabolic measure in the participants of this study. However, the potential impact of psychobehavioral factors on metabolic control needs to be further explored in larger samples of underserved populations using a longitudinal biobehavioral design.;Keywords: type 2 diabetes, depression, stress, metabolic control, self-management behaviors, self-care and self-monitoring.
