Diabetes Mellitus is one of the most prevalent diseases in the world. In Brazil, 8.7% of the population between 20 and 79 years of age has diabetes, estimating 11.6 million diabetics. It is commonly associated with other co-morbidities such as hypertension, dyslipidemia and obesity, which put these patients into a high cardiovascular risk profile. This study was performed using the medical records of enrolled population attending a Family Health Unit of Alto do Coqueirinho, Salvador, Northeastern Brazil, consisting of one doctor, one nurse, one dentist, one nursing technician and six community health workers. Medical records and data provided by the system of the Primary Care Information (SIAB), showed total of 2495 patients. Considering the prevalence morbidities in this population, hypertension was present in 9.8% of patients and Type 2 Diabetes in only 3.6%. Since the prevalence of morbidities is the key indicator to the development of public health policies, it seems important a better knowledge on the prevalence rates of diabetes, prediabetes and its co-morbidities of this population. Future plans and projects for health professionals will be based on a consistent medical record.
