OBJECTIVE: To assess relationships between hypoglycaemic awareness and diabetes-related, psychosocial and demographic characteristics. METHOD: Ninety-eight type 1 diabetic patients completed questionnaires on somatic awareness (Somatic Awareness Questionnaire, SAQ), negative affectivity (Positive And Negative Affectivity Schedule, PANAS), symptom beliefs, bustle and variety of daily life. They then performed up to 70 measurements on a hand-held computer, during 4 to 6 weeks, at home. During every measurement, they rated the presence of 20 symptoms on a 0-6 scale, and estimated and measured their blood glucose level. The percentage of recognised hypoglycaemic episodes was calculated from these data, and used as a measure of hypoglycaemic awareness. RESULTS: Hypoglycaemic awareness was negatively associated with disease duration and antecedent hypoglycaemia, and positively associated with the use of an insulin pump instead of injections, variety in the daily life, somatic awareness, sensitivity of the symptom beliefs and female gender. However, only 17% of the variance in hypoglycaemic awareness was explained. CONCLUSIONS: Psychosocial variables contribute to hypoglycaemic awareness, to a moderate but statistically significant extent.
