Perirenal Fat and Association With Metabolic Risk Factors: The Uberlândia Heart Study.

Perirenal fat (PRF) is associated with cardiovascular risk factors. Gender differences in the correlations of cardiovascular disease risk factors and PRF in the Brazilian population are lacking.Cross-sectional study with 101 (50.49% men; mean age 56.5 ± 18, range 19-74 years) drawn from the Uberlândia Heart Study underwent ultrasonography assessment of abdominal adipose. For the PRF, a 3.5 MHz transducer was measured in the middle third of the right kidney, with the transducer positioned at the axillary midline. The examinations were always performed by the same examiner. The PRF thickness was examined in relation to waist circumference, blood pressure, and metabolic risk factors. The PRF was significantly associated with the levels of gamma-glutamyl transferase (P < 0.05, r = 0.08), fasting plasma glucose (P < 0.05, r = 0.07), waist circumference (P < 0.05, r = 0.10), and metabolic syndrome (P < 0.001, r = 0.38) in men, and with the levels of fasting plasma glucose (P < 0.05) in women.The PRF was correlated with most cardiovascular risk factors in men and only in glucose at the women.
