OBJECTIVE--To test the hypotheses that chronic psychosocial stress is
associated with worse glycemic control and that coping moderates (buffers)
this effect. RESEARCH DESIGN AND 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.
