Abstract:
Objective To observe the serum adiponectin, leptin level, and adiponectin/leptin ratio (A/L ratio) in elderly male patients with normal BMI and visceral adipose deposit but without metabolic syndrome. Methods A total of 109 elderly males (≥60 years old) were enrolled whose BMI were all less than 25 kg m and without metabolic syndrome. They were divided into non visceral adipose deposit group (n = 67) and visceral adipose deposit group (n = 42 ). Serum levels of adiponectin and leptin were measured by radiological immunological assay (RIA) and the A/L ratio was calculated. Visceral adipose deposit was defined as visceral adipose area more than 100 cm2.Metabolic syndrome diagnosis was according to the definition provided by China Diabetes Society (CDS) in 2004. Results (1)The visceral adipose area [(135.56±31.72)cm2 vs. (68. 65±22.64)cm2 , P＜ 0. 001] and BMI [(22.94 ± 1.35 ) kg/m2 vs. ( 21.38 ± 2.55 ) kg/m2 , P ＜ 0.001] were significantly higher in visceral adipose deposit group than in non visceral adipose deposit group. The A/L ratio was significantly lower in visceral adipose deposit group than in non visceral adipose deposit group ( 2. 17 ± 1.77 vs. 4.54 ± 7.00, P = 0. 034 ) while there was no difference in serum adiponectin or leptin level between those two groups. (2)The A/L ratio was negatively correlated with BMI (r=-0.552, P＜0.001), waist circumstances (r=-0.390, P＜0.001) and abdominal visceral fat area (r=-0.341, P＜0. 001 ). Conclusions The A/L ratio decreases in elderly men with normal BMI and visceral adipose deposit. A/L ratio could be useful in scanning those patients with visceral adipose deposit whose BMI is normal among elderly men.
