OBJECTIVES: To propose objective ratios using anthropometry and dual-energy X-ray absorptiometry (DXA) and to suggest cutoff points for them in order to classify lipodystrophy in male patients.
METHODS: It is a cross-sectional study. DXA was applied and anthropometric measurements were performed in 100 men on highly active antiretroviral therapy. Receiver operating characteristic curves were used to propose cutoffs. Individuals were divided in without (lipo-) or with (lipo+) lipodystrophy and their metabolic parameters were compared.
RESULTS: The following ratios were proposed: fat mass ratio by DXA (FMR), waist thigh ratio (WTR), waist calf ratio (WCR), and arm to trunk ratio (ATR). The best cutoffs observed for FMR, WTR and ATR were 1.26, 1.74 and 2.08, respectively. Using the proposed cutoff for FMR, we observed worse metabolic profile, with increased tryglicerides, fasting serum glucose and more hypercholesterolemia in the lipo+ group. WTR and ATR showed a significant correlation with FMR.
CONCLUSIONS: Anthropometric ratios (WTR/ATR) and FMR can be used to aid the diagnosis of lipodystrophy in order to contribute to a more accurate and earlier diagnosis permitting intervention and even preventing metabolic disturbances.
