Abstract

Background: The positive association between waist circumference (WC) and hypertension (H), diabetes mellitus (DM) and heart disease (HD) is well established and evaluated from critic values that showed this association in adults, however, this relationship should be investigated in the elderly due to physiological changes in this population group. Objective: To determine the association between waist circumference in 2000 and H, DM and HD, reported by elderly individuals in 2006, and identify critical values of CC with better discriminatory power among elderly with or without disease. Methods: This was a longitudinal study using data from the SABE Study: Health, Wellness and Aging, held in São Paulo, in 2000 and 2006. The study population was comprised of elderly individuals who did not report H, DM and HD in 2000, and who had WC value. The study variables were WC (continuous variable) and body mass index (<28 kg/m2 and e 28 kg/m2), measurements made in 2000, sex, age group (60 to 74 and e 75), ethnicity (caucasian and others), and H, DM and HD, referred in 2006. To verify the association, the Rao & Scott test for complex sample was used (p <0.05), and multiple logistic regression. The area under the ROC curve (AUC) was used to estimate the overall performance of critical values of CC discriminate elderly correctly according to the reference or not reference the diseases that were associated with WC. The critical value with maximum addition of sensitivity (SE) and specificity (SP), of the values that had at least SE =50% and SP=50% was identified as the value of WC with better discriminatory power among elderly with or without disease. For each critical value are presented the positive likelihood ratio (LR+) and negative (NL-). All calculations were carried out using Stata version 10.0.
