The EURODIAB IDDM Complications Study, a cross-sectional, clinic-based study, was designed to measure the prevalence of diabetic complications in stratified samples of European insulin-dependent diabetic (IDDM) patients. As diet may be related to diabetic complications, nutritional intake was analysed in the study population. The aims of this first nutritional paper are to describe the nutrient intake in 2868 IDDM patients from 30 centres in 16 countries throughout Europe, to investigate the degree of regional differences in nutrient intake and to compare current intakes with recommended levels. Nutritional intake from 1458 male and 1410 female IDDM patients was assessed by a validated 3-day record (two weekdays, Sunday) and centrally analysed. Mean energy intake for all patients was 2390 +/- 707 kcal/day. Mean protein intake was 1.5 +/- 0.5 g/kg body weight. Carbohydrate intake was 43% and fibre intake 18 g/day. Alcohol intake for the total cohort was 2% of energy. Total fat contributed 38% of energy, with 14% from saturated fat. The Italian centres reported lower total and saturated fat intakes compared with other centres. Recommendations from the Diabetes and Nutrition Study Group of the EASD for total fat, saturated fatty acids and carbohydrate were only achieved by 14%, 14% and 15% of patients, respectively. The data of the present study clearly indicate current problems in the nutritional intake of European IDDM patients. These findings contribute to the definition of future targets in the nutritional management of IDDM patients, to be achieved as part of the initiatives taken by the St. Vincent Declaration action programme.

It should be assessed in the population of interest. This study evaluated the repeatability of nutritional data from standardized three-day dietary records, from the clinic-based, cross-sectional multi-centre EURODIAB IDDM Complications Study. Design and Subjects: 15% of the total EURODIAB cohort was randomly selected to test the repeatability of nutritional intake data. Two three-day records, completed three weeks apart, were available for 216 diabetic patients (7.5%) representative of the total cohort. All records were analysed centrally, for intakes of protein (animal and vegetable), fat (saturated fat and cholesterol), carbohydrate, ®bre, alcohol and energy. Repeatability was measured comparing mean intakes, determining the proportion of patients classi®ed into the same/opposite quartile by the two three-day records and assessing mean differences with standard deviations (s.d. d ).Results There were no signi®cant differences in mean energy and nutrient intakes between the ®rst and second records. Classi®cation of individuals into the opposite quartile occurred only in 0±4% of patients and overall about 50% (range 44±74%) of the subjects were classi®ed into the same quartiles of intakes. Only small mean differences were found for energy intake (7156 (1633) kJ; 95% con®dence limits 7375, 63 kJ) and nutrients with s.d. d s comparable to intra-individual variations in the general population. The differences in energy intake were randomly distributed over the range of intakes. Conclusions: The present study demonstrates that standardized three day dietary records show a high degree of repeatability within a short period of time in a sample of European IDDM patients. The good repeatability strengthens the conclusions drawn from the nutritional data in the EURODIAB IDDM Complications Study.
Kidney disease is a common and costly complication [1,2] of diabetes mellitus, with individuals often requiring dialysis or renal transplantation. More than 30 % of people with insulin-dependent diabetes mellitus (IDDM) are at risk of manifest renal disease [3][4][5]. In the EURODIAB IDDM Complications Study 30.6 % of a stratified European sample of individuals with IDDM aged 15-60 years (mean diabetes duration: 15 years) had albumin excretion rates (AER) of 20 m g/min or higher. In persons with a diabetes duration of 1-5 years the rate of elevated AER was 19.3 % [6]. This high prevalence of micro-and macroalbuminuria even early in IDDM and its predictive association for both clinical nephropathy [7][8][9][10][11][12] and increased cardiovascular disease risk [6,[13][14][15] highlight the potential for early detection and effective prevention of diabetic vascular complications.The use of low protein diets has been shown to reduce the progression of nephropathy in patients with clinically overt diabetic nephropathy [16][17][18][19]. In Diabetologia (1997) Summary For people with insulin-dependent diabetes mellitus (IDDM) renal disease represents a lifethreatening and costly complication. The EURODI-AB IDDM Complications Study, a cross-sectional, clinic-based study, was designed to determine the prevalence of renal complications and putative risk factors in stratified samples of European individuals with IDDM. The present study examined the relationship between dietary protein intake and urinary albumin excretion rate (AER). Food intake was assessed centrally by a standardized 3-day dietary record. Urinary AER was determined in a central laboratory from a timed 24-h urine collection. Complete data were available from 2696 persons with IDDM from 30 centres in 16 European countries. In individuals who reported protein consumption less than 20 % of total food energy intake, mean AER was below 20 m g/min. In those in whom protein intake constituted more than 20 %, mean AER increased, a trend particularly pronounced in individuals with hypertension and/or poor metabolic control. Trends reached statistical significance for intakes of total protein (% of energy, p = 0.01) and animal protein (% of energy, p = 0.02), while no association was seen for vegetable protein (p = 0.83). These findings support the current recommendation for people with diabetes not to exceed a protein intake of 20 % of total energy. Monitoring and adjustment of dietary protein appears particularly desirable for individuals with AER exceeding 20 m g/min (approximately 30 mg/24 h), especially when arterial pressure is raised and/or diabetic control is poor.

In the long term, there were few differences in the outcome of the three dietary prescriptions. Even with intensive instruction, participants found it difficult to meet recommended nutrient intakes; however, specific dietary advice did result in an improvement in LDL cholesterol. Adverse changes in HDL cholesterol and TG because of diet intervention were transient. The significant improvement in glycemic control during the recruitment phase may have been the result of participants' previous dietary knowledge and the increased attention that they received during the intervention.
