Prediabetes is a major public health problem that increases the risk of developing type 2 diabetes mellitus and cardiovascular complications. Young adults represent an important age group in which early detection and intervention may prevent progression of the disease. The present study aims to identify factors associated with prediabetes and metabolic complications, and classify individuals based on clinical and biochemical profiles according to insulin resistance, dyslipidemia and fatty liver. This is an observational, cross-sectional study that will be conducted at Assiut University Hospital. Data will be collected through clinical examination, laboratory investigations, and assessment of metabolic profiles.
