On multivariate logistic analysis, the presence of diabetes was independently associated with age (beta = 1.06 (1.02–1.10), P < 0.001) and serum ferritin levels (2.11 (1.34–3.12), P = 0.001) in a model that included migration status, gender, waist to hip ratio, anaemia, serum triglycerides, serum insulin, HDL cholesterol, and systolic blood pressure. Here, INS is linked to anemia.
