Abstract

The objective of the study was to evaluate the association between infectious diseases and other events pertaining to childhood medical history and type 1 diabetes. A case-control study was carried out, taking as cases 159 type 1 diabetic patients (0–29 years) recorded from 1988 to 2000 within the population registry of the Pavia province (North Italy). As controls 318 non-diabetic subjects were matched by age and sex. A questionnaire was administered by standardised interviewers. Data were analysed by conditional logistic regression. Viral childhood diseases (OR 4.29; 95%CI 1.57–11.74) and bottle feeding (OR 1.83; 95%CI 1.08–3.09) were directly correlated to type 1 diabetes; an inverse correlation was found for vitamin D administration during lactation (0–14 years) (OR 0.31; 95%CI 0.11–0.86) and for history of scarlet fever in both sexes and age groups (OR 0.19; 95%CI 0.08–0.46). Most associations of the studied variables confirm already known findings. The significant inverse correlation of type 1 diabetes with scarlet fever history is a peculiar finding, the meaning of which is still obscure, although it has been recently described that streptococcal A infections are regulated by HLA class II alleles.
