The common clinical assumption that stress has a deleterious effect on
metabolic control in insulin dependent diabetes mellitus (IDDM) has n
ot been confirmed in children and adolescents. This cross sectional st
udy of 43 children and adolescents with IDDM and their families examin
ed the relations between family life stress, family social support, an
d metabolic control. High family life stress was found to be strongly
correlated with HbA(1c) in the whole group (n=43) and in children unde
r 12 years (n=27) when considered separately. Family social support wa
s not found to be directly related to HbA(1c), but was found to buffer
the effects of family life stress. These findings support the hypothe
ses that family stress affects metabolic control in IDDM and that good
social support buffers these deleterious effects.
