Therefore, this study aims to determine the prevalence of lipid abnormalities and the validity of BFA as a screening tool. Method: Using crosssectional design, this study was located in Pundong that had rural characteristics. With convenience sampling method, subjects were 82 elderly in 4 hamlet. Lipid abnormalities were measured by BFA. Blood cholesterol became gold standard on the cut off point of 239 mg/dl. Diagnostic test is made using 2x2 table calculation and X2 test. Results: This study found the prevalence of overweight and obesity (19.5% and 2.4%), prevalence of abnormal body faat (75.6%); prevalence of abnormal abdominal fat (20.8%); and prevalence of hypercholesterolemia (15.9%). Best validity demonstrated by the examination of a single Body Mass Index (BMI) (sensitivity 61.54%, specificity 85.51% NDP 44.44%; nd 92.19%, p=0.001). Conclusion: This result most closely approximates the prevalence in rural China. Besides being more valid, a single BMI checks are also easier and cheaper than the BFA. Therefore, the use of normal scales can be maximized. BMI measurement and interpretation should be socialized
