RESUMO

Abstract Background: Cardiovascular risk (CVR) monitoring is important for defining preventive actions against cardiovascular disease; this condition prevails more intensely in scenarios with less infrastructure such as African descent communities. The Framingham Risk Score (FRS) and the Global Risk Score (GRS) have been used in Brazil for CVR monitoring based on scales of points for certain risk factors. Among these, hypercholesterolemia and low high-density lipoprotein cholesterol require tests not always available in primary care. An alternative would be the simplified GRS (sGRS), in which these tests are replaced by the body mass index (kg/m2). Objective: To determine the accuracy of the sGRS in estimating CVR in African descent women (quilombolas) from Alagoas. Method: This is a cross-sectional study with a representative sample (n=1015) of women from African descent communities in Alagoas. GRS, sGRS, and FRS consisted in the sum of points obtained according to their respective scales. Receiver operating characteristic curves were used to compare the accuracy of these instruments as CVR predictors, assuming the GRS as reference. Statistical significance was assumed when p<0.05. Results: The prevalence of high CVR assessed with the GRS or sGRS was similar (20.1% vs. 20.7%; p>0.05) and higher than that found with the FRS (4.5%; p<0.001). Considering the area under the curve (AUC), the sGRS had a higher discriminatory power (AUC=0.98; 95%CI: 0.98–0.99) than the FRS (AUC=0.91; 95%CI: 0.90–0.93). Conclusion: Among black women living in regions with less infrastructure, the sGRS produced similar results to the GRS, with greater operational simplicity.
