ABSTRACT
OBJECTIVES: Despite significant advances in medical therapy and unrestricted access to health care, >50% patients with type 2 diabetes (T2D) cannot maintain their blood glucose target levels. This cross-sectional study investigated the association between psychosocial behaviour and diabetes management in Newfoundland and Labrador, where the prevalence of T2D is the highest in Canada. METHODS: Data were collected from 165 adult T2D patients. Four sets of self-administered standardized questionnaires, a study-specific data form and electronic health records were utilized to obtain psychosocial information, patient characteristics and glycated hemoglobin (A1C) levels. RESULTS: The group of participants with emotional burnout due to diabetes-related stress showed poor glycemic control (89.4%) compared to the group with low stress (55.6%). The group with higher stress appraised T2D negatively (correlation coefficient r=0.719, and p<0.01), and had a tendency to use emotion-oriented coping (r=0.542, p<0.01) and had a poor perception of autonomous supportiveness (r=-0.300, p<0.01). A path model showed that stress, appraisal and coping explained 7.4% of the variance in A1C. Appraisal plays the role of mediator and explained 5.8% of the variance in A1C. CONCLUSIONS: A high prevalence of poor glycemic control was found in participants with a body mass index of ≥35. Participants with higher stress had a negative appraisal of T2D. The highly stressed group tended to use emotion-oriented coping and have a poor perception of autonomous supportiveness.
