OBJECTIVES: The aim of the current study was to assess the patient characteristics, treatment patterns and health outcomes of adult patients with type 2 diabetes (T2D) with and without comorbid obesity in Brazil. METHODS: Data were obtained from the Brazil 2011 National Health and Wellness Survey, a self-reported patient survey of the adult Brazilian population (N=12,000).  Obese T2D patients (n=155) were compared with non-obese T2D patients (n=320) on demographics, HbA1c, insulin usage, health behaviors and prevalence of hypertension and high cholesterol.  Differences amongst the two groups on levels of health status (assessed with the SF-12) were also analyzed in a series of multiple regressions, controlling for the effects of patients’ socioeconomic status.  RESULTS: T2D patients were mostly male (53.89%) and had a mean age of (54.97). A total of 87.79% of patients did not know their HbA1c and only 16.21% were on an insulin, neither of which varied by presence of obesity.  Obese T2D patients were significantly more likely to belong to B1 socioeconomic group and significantly less likely to belong to C1 socioeconomic group than non-obese T2D patients (30% vs. 21% and 10% vs.19%, respectively, all p<0.05).   Hypertension was significantly more prevalent among obese T2D patients than among non-obese T2D patients (61% vs. 43%, p<.05).  Adjusting for differences in socioeconomic status, obese T2D patients reported significantly lower levels of PCS (Adjusted Mean (Madj)=42.7 vs. 44.6, p<.05) and had significantly lower health utilities than non-obese T2D patients (Adjusted Mean (Madj)=0.68 vs. 0.72, p<.05).  CONCLUSIONS: Few patients in Brazil were aware of their HbA1c, suggesting a lack of patient education. ObeseT2D patients were more likely to report comorbid hypertension and worse health status yet were no more likely to use insulin than their non-obese counterparts.  Improved patient education and management of obese T2D patients may improve health outcomes for these patients.
