Childhood diabetes towards the 21st century

A nursing educational intervention helped by One Touch UltraSmart improves monitoring and glycated haemoglobin levels in type I diabetic children

OBJECTIVES

To improve the monitoring and control of glycated haemoglobin in insulin-dependent children. This article describes an educational intervention for this purpose where One Touch UltraSmart Software was used to manage diabetes. The results showed that this intervention helped to reduce the levels of blood glucose and glycated haemoglobin to less than 7%.

BACKGROUND

Various research studies have been performed on the effective control of glycated haemoglobin values in diabetic children by means of technological devices. However, none of this research has evaluated the impact of an educational intervention in conjunction with the use of monitoring instruments such as One Touch UltraSmart.

DESIGN

We present an 18-month longitudinal, analytical and observational study of 37 type 1 diabetic patients, 9-16 years of age. For each patient, initial and final values of glycated haemoglobin and the number of blood glucose controls were recorded.

METHODOLOGY

For the purposes of our study seven educational workshops, attended by diabetic children and their parents, were conducted. In addition, participants were asked to complete a brief questionnaire so that information could be gathered regarding the eating and exercise habits of the patients.

RESULTS

This educational intervention using One Touch UltraSmart led to a statistically significant average reduction of glycated haemoglobin.

CONCLUSIONS

Our research showed that the use of One Touch UltraSmart in the context of an educational intervention raised the awareness of the diabetic children and thus helped them to effectively control their disease and to fully understand the necessity of having good dietary and exercise habits.

RELEVANCE TO CLINICAL PRACTICE

It can be concluded that the educational intervention led to a significant improvement in the dietary habits of these patients and also helped them to exercise regularly, all of which has a positive impact on their health.

Interplay between heredity and environment in the recent explosion of type 1 childhood diabetes mellitus

The fast increase in the incidence of childhood type 1 diabetes mellitus (T1DM) that cannot be explained by changes in the genetic susceptibility, led us to look for environmental causes. To test the hypothesis that the initiation of the autoimmune process of childhood T1DM in genetically susceptible subjects begins in the perinatal period by a viral infection, we studied the seasonal variations in the month of birth of several cohorts of patients compared to the general population. Population groups with high or low T1DM incidence were analyzed separately by t-test and the Cosinor methods. In areas with populations with a high incidence (Israeli Jews, Sicily, Sardinia, Slovenia, Germany) we found that the children (in Sicily also young adults) who subsequently developed T1DM, have a higher incidence of births in the summer months than in other seasons of the year, a mirror image of the seasonality of the clinical onset of disease. This pattern differed significantly from the seasonality of the total live births in the same populations. In populations with a low T1DM incidence, (China, Japan and Cuba) no seasonality of month of birth was found. Similar findings have been reported, from five counties in the U.K. and the Netherlands. It is hypothesized that mothers who become pregnant during the period of yearly viral epidemics transmit to the fetus, either a virus or antiviral antibodies, which determine whether an autoimmune process against the pancreatic beta is initiated or whether the fetus is protected against that process.

Seasonality of birth in children (0-14 years) and young adults (0-29 years) with type 1 diabetes mellitus in Sardinia differs from that in the general population. The Sardinian Collaborative Group for Epidemiology of IDDM

A cohort of 1,118 children (0-14 years) and 810 adolescents and young adults (15-29 years) with type 1 diabetes mellitus (DM) diagnosed in Sardinia between 1989 and 1998 were analyzed for seasonality of month of birth, and compared to the pattern registered in 314,084 live births. Patients with DM of both age groups had a statistically significant different seasonality pattern from the general population, revealing an increased birth rate during the summer months, a mirror image of the seasonality of onset of disease.

Seasonality of birth in children (0-14 years) with type 1 diabetes mellitus in Slovenia

The aim of this study was to find out whether there is seasonality of month of birth of children with diabetes in Slovenia and if so whether it differs from that of the general population. A cohort of 849 children and adolescents (0-14 years) with type 1 diabetes mellitus born between 1956 and 1998 were included in the study. Monthly and seasonal patterns of birth of the patients with diabetes were compared with the pattern of normal live births (n = 1,345,921) and the pattern of disease onset. Statistical analysis was made using Student's t-test to compare the means between the four seasons of the year, and single cosinor analysis for a period of 12 months. The children and adolescents with diabetes had a statistically significant different seasonality of month of birth compared to that of the general population, and an opposite pattern from the seasonality of month of onset of disease. The observations made are in accordance with observations made recently in other countries and support the hypothesis that a virus infection transmitted by the mother to the fetus during the annual viral epidemic induces the autoimmune process in the pancreatic beta-cells in genetically susceptible individuals who will subsequently develop clinical diabetes during childhood.

Seasonality of birth in children (0-14 years) with diabetes mellitus type 1 in Baden-Wuerttemberg, Germany

The aim of the study was to find out whether children with diabetes type 1 in Baden-Wuerttemberg present a pattern of seasonality in their month of birth. A cohort of 1,184 children and adolescents (0-14 years) diagnosed as having diabetes between January 1st, 1987 and June 30th, 1997 were included in the study. Monthly and seasonal patterns of birth of patients with diabetes were compared with the pattern of normal live births (n = 2,724,746) during the years 1972-1997 and the seasonality of onset of disease. Statistical analysis was made using Student's t-test to compare the means between four yearly seasons and single cosinor analysis for a period of 12 months. The children and adolescents with diabetes had a significantly different seasonality in month of birth pattern from that registered in the general population, demonstrating fewer births during the months April-June and July-September. This seasonality pattern also differs from those registered in Israel, Sardinia and Slovenia, in which the population with diabetes type 1 had most births during these months.

Month of birth and subsequent development of type I diabetes (IDDM)

The aim of this study was to find out whether there is a seasonal pattern in the month of birth of children with IDDM in Israel and whether this pattern, if present, differs from that of total live births. One thousand and ninety-five out of 1,188 children and adolescents (0-17 years) who developed IDDM in Israel between 1980-1993 and whose month of birth was known were included in the study. Separate analysis was made for Jews (n = 987) who have a high incidence (10-18/105) and Arabs (n = 108) with a low incidence (2.9/105) of IDDM. The pattern of total live birth distribution in Israel over a 20-year period served as control. A significantly different seasonal pattern was found in the two IDDM populations. Whereas the Jews had the lowest number of births in winter (January-March) and the highest in spring (April-June), the Arabs presented an inverse pattern in the first months of the year. The distribution of births of the children who developed IDDM was different from that observed in total live births in the Jewish population. The findings in the Jewish population in Israel (a high incidence group) support the hypothesis that IDDM is triggered in some children by viral infections transmitted by the mother during pregnancy or in the early postnatal period. In the Arab population (a low incidence group) a protective (immune and/or genetic) mechanism may exist.
