Birth Weight and Childhood Onset Type 1 Diabetes: A Case-Control Study in Shiraz, South of Iran

Abstract

To determine the relation between birth weight and age of presentation of type 1 diabetes and assess its risk factors, a case-control study was done on all diabetic patients under the age of 15, who were registered in Shiraz Diabetic Center or admitted in Namazi Hospital. A case group of 87 diabetic patients were matched with a control group of 100 healthy individuals. Birth weight ≥ 4kg was determined to be a risk factor for diabetes (odds ratio: 2.04). A weak association was found between birth weight ≤ 2.4 kg and diabetes development.Iran J Med Sci 2006; 31(3): 164-166. Keywords ● Birth weight ● diabetes mellitus type 1 ● risk factors
