RESUMO
Nutrition management is an integral part of overall diabetic treatment that includes insulin, physical activity, emotional support and guidance. The aim of the present study was to evaluate a dietary approach in line with the recommended dietary allowances in terms of protein, total and saturated fat, carbohydrates as well as fibre and polyunsaturated fatty acid. A correct dietary approach may help to prevent and to reduce to a minimum any risk of hyperglycaemia, hypoglycaemia and important long-term complications such as obesity, hyperlipidaemia and hypertension, and at the same time normal growth development.

A diet in line with RDAs is seldom achieved by IDDM patients. High post-prandial glucose levels are often attributed to food excess rather than to inadequate insulin doses. Lower dietary CHO with greater fat (in particular SFA) and protein are progressively scheduled instead of increasing insulin units. We studied 194 IDDM patients (1-23 yr) on a diet conforming to RDAs with a restriction of sucrose and without a quantitative approach and exchange lists of food for one year. The diet consisted of a high intake of starchy foods and vegetables and a restricted amount of animal products. HbA1c mean values of the year were used as an indicator of metabolic control. The mean daily insulin dose was 0.53 U/kg in patients with diabetes duration (DD) < 2 yr and 0.81 U/kg in those with DD > 2 yr. Mean annual HbA1c was 7.1 +/- 0.9%. The prevalence of obesity was low (5.7%). Adolescent females were more obese than males. A dietary approach in line with RDA requirements, that may help prevent any complications related to an inappropriate diet pattern, coupled with a dynamic insulin adjustment, is the first-line intervention to prevent complications in IDDM patients.

The objective of this study was to provide reliable data on the incidence of type 1 diabetes, in children aged 0-14 years, in the Veneto region, and to better understand its geographical variability throughout Italy and Europe. All new cases of type 1 diabetes diagnosed between 1st January 1993 and 31st December 1994 among residents in Veneto were recorded. Clinical records from 33 hospitals in the region were used as the primary source for this study. The number of disease-related free-of-charge prescriptions served as a secondary source. The completeness of ascertainment was estimated at 89%. The mean incidence estimated over the 1993-1994 period was 10.7 per 100,000/year. The Veneto region appears to have a relatively high incidence of IDDM among non-insular Italian regions. No significant sex-related difference in incidence was noted; the male/female ratio was 1.5.

This study was performed to analyse the prevalence of obesity in children living in six different areas of the north-east of Italy. The study included 1523 children (749 male, 774 female), divided into four age categories (4, 8, 10, 12 +/- 0.5 years of age, respectively). The physical characteristics of the children were measured by trained and standardized examiners. In accordance with the guidelines on the Italian Consensus Conference on Obesity (Rome, 4-6 June 1991), a child was defined as obese when his weight was higher than 120% of the weight predicted for height, as calculated from the Tanner's tables. On average, the prevalence of obesity was higher in males than in females (15.7% vs. 11%). The highest prevalence was seen in 10-year-old males (23.4%). The prevalence increased with age both in males (4 years = 3.6%, 8 years = 11.2%, 10 years = 23.4%, 12 years = 17.3%) and in females (4 years = 2%, 8 years = 13.3%, 10 years = 12.7%, 12 years = 11.9%). This tendency was maintained when calculating the obesity prevalence by other methods, such as BMI, triceps skinfold and fat mass, although the magnitude of the prevalence was different depending on the criteria used to define it. A consensus on more precise criteria to define obesity is needed for a better diagnosis of obesity in childhood and to allow a more reliable measurement and comparison of the prevalence of obesity among populations.

The purpose of our study was to evaluate the relationship between the histocompatibility antigens and type I diabetes mellitus in families living in the north-eastern part of Italy. In each family two siblings were affected by diabetes. HLA-antigens were determined with the lymphocytotoxicity test, utilizing antisera of the series A-B-C-DR. The phenotypic frequencies were compared with those observed in controls. We showed that diabetes has a strong association with HLA DR 3 and/or DR 4 antigens. In particular we registered high frequency of compound heterozygous DR 3 - DR 4 subjects, and this fact supports the hypothesis of the existence of two different genes for diabetes associated with these HLA antigens. Moreover we observed a particular haplotype segregation with a very high percentage of HLA identity between patients belonging to the same family, confirming the association between HLA and genetic susceptibility to insulin dependent diabetes. These results confirm data in the literature and, completed by other data from other patients' families living in our area, will be useful in providing reliable genetic counselling.

Exercise is worth while for general health and well being; and is beneficial and safe for the young with IDDM as well. The patient must learn to adapt to insulin and/or diet, attending education and training program. The many examples of world-class athletes and participants in the Olympic Games with diabetes serve as impressive evidence that in spite of being dependent on insulin, they are able to participate successfully and without complications in physical activities and high-performance sports.

The so called diabetic diet, with a high intake of protein and fat, grown up in order to gain a better glycemic control, can be responsible for long term impairment of macro-angiopathic complication. For this reason many paediatric diabetologists, according to recent Dietary Allowances, recommend to diabetic children and adolescents a diet with the following characteristics: A variable total energy intake based on energy need High content of starch, particularly rich in soluble fibres Protein content lower than usual intake Increased mono and polyunsaturated fats.

Autonomic function has been studied in 30 insulin-dependent diabetic children and adolescents, through five cardiovascular tests. A significant difference between the diabetic and the control subjects was found in heart rate variations after deep breathing and after standing. Fifty percent of our patients showed an altered response to one or more cardiovascular tests. Although clinical manifestations of autonomic dysfunction are not frequent in young insulin-dependent patients, early signs of functional alterations are detectable in a high percentage of them.

Visual evoked potentials were studied in 30 insulin-dependent diabetic children and adolescents. Thirty percent of the subjects had evidence of significant abnormalities. No correlation was found between visual evoked potentials and age, duration of diabetes, metabolic control, and retinopathy.
