[National campaign to detect suspected diabetes cases in Brazil: a preliminary report]

The Ministry of Health of Brazil is implementing a National Plan for the Reorganization of Health Care for Hypertension and Diabetes Mellitus, with the aim of reducing the morbidity and mortality associated with diabetes. This plan is divided into four stages, one of which was a national campaign to detect suspected diabetes cases that was carried out in March and April 2001. This was the first survey of its kind carried out by public health services in Brazil, and the preliminary results are described in this article. Out of a total of 5,507 participating municipalities, 4,446 of them (81%) submitted data to the Ministry of Health. Twenty million people were tested (71% of the target population), and 3.3 million of them were identified as possibly having diabetes. The campaign will contribute towards restructuring the systematic and resolution-oriented care that the national, public Unified Health System provides to diabetics. The preliminary results confirm that diabetes is one of the main health problems in Brazil. Priority should be given to preventing type 2 diabetes.
