Effect of temperament on metabolic control in children with diabetes mellitus

Fifty-one children with insulin-dependent diabetes mellitus (IDDM) and 24
healthy sibling controls were compared on one of two temperament
questionnaires completed by parents. Children with IDDM did not provide a
characteristic temperament profile or show any problem areas. A regression
analysis to predict diabetic control as measured by most recent
glycosylated hemoglobin (HbA1c) values revealed that five of the nine
temperament scales accounted for a significant 42% of the variance in HbA1c
(P less than .001). Children with higher activity levels, greater
regularity in routines, milder reactions to external stimuli,
distractibility, and negative moods were achieving better glycemic control.
The results are discussed in terms of how individual differences in
behavioral organization, energy consumption, and stress modulation may
affect blood glucose levels.
