    Notes: Summary The objective of this study was to identify possible risk factors of severe hypoglycaemia (SH) in a prospective population based study of adult Type I (insulin-dependent) diabetic patients. A representative sample of 684 patients (41 % women, mean ± SD age 36 ± 11, diabetes duration 18 ± 11 years), living in the district of Northrhine (9.5 million inhabitants), Germany, were examined in their homes using a mobile ambulance. A comprehensive baseline assessment of possible predictors of SH included sociodemographic and disease related variables, hypoglycaemia awareness, diabetes management, and attitudes and behavioural aspects as expressed by the patients. After a mean of 19 ± 6 months 669 (98 %) patients were interviewed about events of SH since the baseline examination. Using the multiple Cox proportional hazards model, five risk factors of SH were identified: SH during the preceding year [hazard ratio (HR) 2.7, 95 % confidence intervals (CI) 1.8–4.2], any history of SH (HR 1.9, CI 1.1–3.4), C-peptide negativity (HR 4.0, CI 1.2–12.7), social status (HR 0.8 for a difference of 5 units for a value range of 0–24, CI 0.6–0.9), and patients' determination to reach normoglycaemia (HR 0.7 for a difference of 1 unit for a value range of 1–6, CI 0.5–0.9), indicating that the lower the social status and the higher the patients' determination to reach normoglycaemia, the higher the risk of SH. After eliminating the history of hypoglycaemia from the model, impaired hypoglycaemia awareness and patients' inappropriate denial of SH as their particular problem became additional significant risk factors of SH. In conclusion, in this population based study of adult Type I diabetic patients, C-peptide negativity, a previous event of SH, patients' determination to reach normoglycaemia and social class were risk factors of SH.

    Notes: Summary The objectives of the present analyses were to assess the association between HbA1 c levels and severe hypoglycaemia (SH, treatment with glucose i. v. or glucagon injection) and to identify predictors of SH in a prospective multicentre trial. The study population consisted of 636 insulin-dependent diabetic patients who had participated in a structured 5-day in-patient group treatment and teaching programme for intensification of insulin therapy (ITTP) in one of 10 hospitals and who were re-examined after 1, 2, 3, and 6 years including assessment of demographic, disease and treatment related parameters, diabetes-related knowledge, behaviour, and emotional coping. At baseline, age (mean ± SD) was 27 ± 7 years, diabetes duration 9 ± 7 years and HbA1 c 8.3 ± 1.9 %. During the 6-year follow-up, the mean HbA1 c value improved to 7.6 %, and in patients with a diabetes duration of more than 1 year at entry into the study (n = 538) the incidence of SH decreased from 0.28 cases/patient/year during the year preceding the ITTP to 0.17 cases/patient/year. The patient group was divided into decile groups according to mean follow-up HbA1 c values. In each group more than 230 patient years could be analysed. Groups with mean HbA1 c values of 5.7, 7.0, 7.4, 7.7 and 8.9 % had comparable risks of SH (0.15–0.19 cases/patient/year). In a logistic regression analysis, mean HbA1 c during follow-up, a history of SH during the year preceding the ITTP, C-peptide level, emotional coping, carrying emergency carbohydrates (as assessed at the 1-year follow-up), and age at onset of diabetes were significant independent predictors of SH. The incidence of SH between centres varied between 0.05 and 0.27 cases/patient/year. In conclusion, in the present analyses no linear or exponential relationship between HbA1 c and severe hypoglycaemia could be identified by using simple group comparisons. Applying complex regression analyses, various patient-related predictors of severe hypoglycaemia were identified. [Diabetologia (1997) 40: 926–932]
