Atherogenic index of plasma is an effective index for estimating abdominal obesity

Abstract

Abstract Background The correlation between the atherogenic index of plasma (AIP) and waist circumference (WC) remains unknown. Methods A total of 5351 middle-aged men living in Southeastern China were surveyed using the random stratified cluster sampling method. A WC of 90 cm or greater was indicative of abdominal obesity, and AIP was calculated as follows: log [triglyceride (TG)/high-density lipoprotein-cholesterol (HDL-C)]. Results (1) A significantly higher AIP was observed in subjects with abdominal obesity than in those without abdominal obesity (P 0·21), WC was >90 cm. Conclusions AIP of 0·12–0·21 or >0·21 indicates a likelihood of borderline abdominal obesity or abdominal obesity, respectively, and the combination of WC and AIP may increase the specificity and sensitivity for detection of abdominal obesity in clinical practice. The results suggest that AIP may be used as a reference to estimate abdominal obesity.
