Stress buffering and glycemic control. The role of coping styles.
OBJECTIVE
To test the hypotheses that chronic psychosocial stress is associated with worse glycemic control and that coping moderates (buffers) this effect.


METHODS
Subjects consisted of 105 insulin-treated adults from the Diabetes Division of Henry Ford Hospital who filled out questionnaires on stress and coping and received an HbA1 test at a clinic appointment. Six coping styles were examined, including both emotion- and problem-focused styles. Two standardized stress inventories were administered. Ineffective coping was defined as scoring below the median for stress-dampening coping styles and above the median for stress-exacerbating styles.


RESULTS
Stress was significantly (P less than 0.05) correlated with higher HbA1 in all but one ineffective coping subgroup. Conversely, none of 12 correlations between stress and glycemic control was significant in the effective coping subgroups.


CONCLUSIONS
Chronic psychosocial stress is associated with worse glycemic control among those who do not cope effectively with stress. Effective coping can protect individuals from the deleterious effects of stress.
