AIMS/HYPOTHESIS: To evaluate the relation between the incidence of childhood Type I (insulin-dependent) diabetes mellitus and the degree of urbanization in the central-southern part of Italy. METHODS: The incidence was determined in two areas: area A encompasses 3 regions of central-eastern Italy (Marche, Abruzzo, Umbria), whereas area B encompasses one southern region (Campania). During 1990-1995, 706 children aged 14 or under with insulin-dependent diabetes mellitus of recent onset were registered. The completeness of the case ascertainment in the registries analysed separately for each region was high, ranging from 96.3 % to 99%. RESULTS: The age-standardized incidence was higher in area A (9.6 per 100000 person per year; 95 % confidence interval: 8.5-10.8) than in area B (5.4 per 100000 person per year; 95% confidence interval: 4.9-6.0). In both areas the standardized incidence ratios increased with the degree of urbanization (chi-squared for trend: area A= 140, p < 0.0001; area B = 79, p < 0.0001). The highest standardized incidence ratios were in the most urban communities. CONCLUSION/INTERPRETATION: This study showed a statistically significant difference in incidence of childhood insulin-dependent diabetes mellitus among different areas of the continental peninsula of Italy. People living in the rural communities appear to have a lower risk.

Abstract

AIMS/HYPOTHESIS: To evaluate the relation between the incidence of childhood Type I (insulin-dependent) diabetes mellitus and the degree of urbanization in the central-southern part of Italy. METHODS: The incidence was determined in two areas: area A encompasses 3 regions of central-eastern Italy (Marche, Abruzzo, Umbria), whereas area B encompasses one southern region (Campania). During 1990-1995, 706 children aged 14 or under with insulin-dependent diabetes mellitus of recent onset were registered. The completeness of the case ascertainment in the registries analysed separately for each region was high, ranging from 96.3 % to 99%. RESULTS: The age-standardized incidence was higher in area A (9.6 per 100000 person per year; 95 % confidence interval: 8.5-10.8) than in area B (5.4 per 100000 person per year; 95% confidence interval: 4.9-6.0). In both areas the standardized incidence ratios increased with the degree of urbanization (chi-squared for trend: area A= 140, p < 0.0001; area B = 79, p < 0.0001). The highest standardized incidence ratios were in the most urban communities. CONCLUSION/INTERPRETATION: This study showed a statistically significant difference in incidence of childhood insulin-dependent diabetes mellitus among different areas of the continental peninsula of Italy. People living in the rural communities appear to have a lower risk.
