Diagnostic value of waist-height ratio to predict cardiovascular disease risk in adults

Purpose: This study aimed to determine the diagnostic strength, optimal cutoff point, and diagnostic value of waist circumference/body height ratio in detecting cardiovascular disease risk in adults with Framingham Risk Score (FRS). Method: This study used a cross-sectional research design using secondary data from the Fourth Wave of the Indonesian Family Life Survey 4 (IFLS 4). Subject selection uses the total sampling method so that the entire study population that matches the inclusion and exclusion criteria will be the subject of this study. The number of research subjects that fit the inclusion and exclusion criteria was 9,103 people. This research uses ROC analysis, with the gold standard is the risk of cardiovascular disease based on FRS, and the independent variable is WtHR. Results: Based on sex, the risk of cardiovascular disease in the moderate category was higher in men (80.54%) compared to women (30.23%). AUC WtHR value in male subjects was 0.5817 (95% CI 0.5610-0.624), while the AUC value in female subjects was 0.5904 (CI 0.5727-0.6084). The optimal cutoff point in male subjects is 0.5249 (sens = 0.3549; spe = 0.7626), while the cut point in female subjects is 0.5796 (sens = 0.4382; spe = 0.7024). Conclusion: The WtHR cutoff value based on this study is 0.5249 and 0.5796, so the health message that can be given to the public to prevent the risk of cardiovascular disease is to keep the waistline less than half the height.
