Comparison of body mass index at diagnosis of diabetes in a multi-ethnic population: A case-control study with matched non-diabetic controls

Abstract

AIMS: To investigate the probability of developing type 2 diabetes mellitus (T2DM) at different body mass index levels compared to matched non-diabetic controls in a multi-ethnic population. MATERIALS AND METHODS: This was a case-control study of 90 367 patients with incident diabetes and 362 548 age-sex-ethnicity matched controls from UK primary care. The probability of developing T2DM was estimated. RESULTS: Case and control patients were 56 years old at index and 56% were male. Patients with T2DM had significantly higher mean BMI levels by about 5 kg/m2 at diagnosis (32.2 kg/m2 ) compared to the matched controls (27.4 kg/m2 ). White Europeans (n = 79 270), African-Caribbeans (n = 4115) an..
