[Foot ulceration risk factors in type 2 diabetes mellitus]

To identify risk factor prevalence for development of foot ulcers in patients with type 2 diabetes (DM2).

A cross sectional study, of 2067 patients with DM2 from seven primary care units was conducted. A questionnaire exploring age, sex, occupation, time from diabetes mellitus diagnosis (DMD), and data concerning neuropathy, vascular changes, and presence of infections, anthropometry, and gait was applied.

We found mean age, 59.96 +/- 11.47 years and time from DMD, 10.2 +/- 8.09 years. From 1360 women, 65.8 % presented the following risk factors: age, 34.7 %; schooling, 49.5 %; time from DMD, 38.8 %; occupation, 20 %; smoking, 24.3 %; alcoholism, 4.6 %; fasting glucose disturbance, 78 %; ulcer history, 10 %. In relation to associated diseases, 67.5 % of patients had one or more antecedent. The presence of risk factors in the sample was 9.716 +/- 2.52, of which 6.259 +/- 1.59 were modifiable.

Patients studied presented high risk factor prevalence for development of foot ulcer. The majority of RF is potentially modifiable by adjusting patients' customs and habits.
