title: [Prevalence of type 2 diabetes mellitus in overweight or obese outpatients in Spain. OBEDIA Study].
abstract: OBJECTIVE
  The increase in the prevalence of type 2 diabetes mellitus (T2DM) is related to the increase of obesity. We aimed to determine the Spanish prevalence of T2DM in patients with overweight or obesity attended by either family or specialist physicians.
  
  
  METHODS
  Cross-sectional, multicenter and simultaneous 2-phase design, performed under clinical conditions. Phase A was designed to determine T2DM prevalence: 169,023 patients were recruited. Phase B was designed to define socio-demographic, clinical and metabolic profile of T2DM according to the body mass index (BMI): 7,754 patients were included.
  
  
  RESULTS
  T2DM prevalence in overweight or obese patients was 23.6%; 17.8% of overweight patients were diabetic and T2DM was present in 34.8% of obese people. According to sex, 20.2% of men and 16.4% of women had T2DM. Overall, the mean of risk factors related to T2DM was 4.4 (SD 0,8); out of them, 92.6% patients had dyslipidemia, 73.7% hypertension and 62.5% performed a low physical activity. 37.8% of diabetic patients had vascular involvement. Only 43.1% of patients showed a proper metabolic control of T2DM (glycosilated hemoglobin<7%).
  
  
  CONCLUSIONS
  T2DM is related to overweight and obesity and higher the BMI is, higher the T2DM prevalence. Dyslipidemia, hypertension and a low physical activity in diabetic patients are more frequent when BMI increases. Patients with inadequate metabolic control have a higher BMI.
