OBJECTIVE: To investigate the presence of psychiatric disorders and
symptoms in type I diabetic patients and to identify those that may
influence metabolic control as assessed by GHb levels. RESEARCH DESIGN AND
METHODS: This was a cross-sectional study. One hundred and two consecutive
patients with type I diabetes who were regular outpatient visitors of a
diabetology department were evaluated. The psychiatric assessments included
self-rating questionnaires (General Health Questionnaire and Fear
Questionnaire) and observer-rating questionnaires (Montgomery-Asberg
Depression Rating Scale [MADRS] and Mini International Interview). Diabetic
characteristics were assessed by a structured interview. The observer was
blind to the diabetic characteristics of the patients. RESULTS: Type I
diabetic patients with GHb levels > or = 8% had higher psychological
distress, scored significantly higher for symptoms of agoraphobia and for
fear of blood and injury, had substantially higher levels of
anxiety-depression, and performed significantly fewer blood glucose
measurements per day. They did not differ in MADRS score from patients with
GHb levels < 8%. Multivariate analysis showed that GHb was positively
associated with the total score of phobic symptoms and the level of
anxiety-depression and inversely associated with the number of daily blood
glucose measurements. These factors explained 41% of the variance of GHb.
The inverse relationship between GHb and the number of blood glucose
measurements per day was mainly influenced by the fear of blood and injury.
Patients with high scores for the fear of blood and injury performed fewer
blood glucose measurements and had poorer glycemic control; conversely,
subjects without fear of blood and injury performed more daily blood
glucose measurements and had better glycemic control. CONCLUSIONS: Phobic
symptoms are frequent in patients with type I diabetes. The intensity of
phobic symptoms and anxiety-depression negatively influences metabolic
control. Increased fear of blood and injury may lead some patients to
perform few home blood glucose measurements and may result in poorer
glycemic control. This suggests that, by decreasing the fear of blood,
injury, and injection, metabolic control may be improved.
