Abstract
BackgroundThe correlation between the atherogenic index of plasma (AIP) and waist circumference (WC) remains unknown.MethodsA 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 < 0·001). (2) Multivariate logistic regression analysis revealed an odds ratio of 1·93, 2·59 and 2·76 for abnormal AIP levels for the second, third and fourth WC quartiles, respectively (all P < 0·001) compared to the first WC quartile as a reference. (3) There was a linear correlation between WC and AIP, and a 1·0 cm increase in WC resulted in a 0·0175 rise in AIP. For AIP corresponding to moderate risk (0·12–0·21), WC was 85–90 cm; for AIP corresponding to high risk (> 0·21), WC was >90 cm.ConclusionsAIP 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.

Summary
The correlation between the atherogenic index of plasma (AIP) and waist circumference (WC) remains unknown. Obesity has become an important public health concern worldwide, and abdominal obesity, which involves fat accumulation in the abdomen, is recognized as an independent risk factor for obesity-related diseases and death [1]. In China, obesity has become a major risk factor for the increased prevalence of cardiovascular diseases [2]. Waist circumference (WC) was used as an index to assess abdominal obesity in middleaged men, and the correlation between WC and the atherogenic index of plasma (AIP) was evaluated to provide evidence for the development of a preventive and control strategy for atherosclerosis and cardiovascular diseases in community populations
