OBJECTIVE
To investigate the relationship between adiposity measures and plasma concentration of high molecular weight (HMW) adiponectin.
METHODS
In a Chinese sample (n = 1081), we performed measurements of anthropometry and bioelectrical impedance analysis (BIA). We defined overweight and obesity as a body mass index between 24 and 27.4 kg/m² and ≥ 27.5 kg/m², respectively, and central obesity as a waist circumference ≥ 90 cm in men and ≥ 80 cm in women. Plasma HMW adiponectin concentration was measured by the ELISA method.
RESULTS
Plasma HMW adiponectin concentration was significantly (P < 0.0001) higher in women (n = 677, 2.47 μg/mL) than men (n = 404, 1.58 μg/mL) and correlated with advancing age in men (r = 0.28) and women (r = 0.29). In adjusted analyses, it was lower in the presence of overweight (n = 159, 1.26 μg/mL in men and n = 227, 2.15μg/mL in women) and obesity (n = 60, 1.31 μg/mL and n = 82, 2.10 μg/mL, respectively) than normal weight subjects (n = 185, 2.07μg/mL and n = 368, 2.94 μg/mL, respectively) and in the presence of central obesity (n = 106, 1.28 μg/mL and n = 331, 2.12 μg/mL, respectively) than subjects with a normal waist circumference (n = 298, 1.74 μg/mL and n = 346, 2.74 μg/mL, respectively). In multiple regression analyses stratified for gender, adjusted for confounders and considered separately each of the adiposity measures, all adiposity measures were significantly (r -0.18 to -0.31, P < 0.001) associated with plasma HMW adiponectin concentration. However, in further stratified and adjusted regression analyses considered stepwise all adiposity measures, only waist-to-hip ratio was significantly (P < 0.05) associated with plasma HMW adiponectin concentration in men (r = -0.10) and women (r = -0.15).
CONCLUSIONS
Anthropometric measures of obesity, such as waist-to-hip ratio, but not BIA measures, are independently associated with plasma adiponectin concentration.
目的
研究肥胖指标与高分子量（HMW）脂联素血浆浓度之间的关系。
方法
在中国样本（n = 1081）中，我们进行了人体测量和生物电阻抗分析（BIA）。我们将超重和肥胖分别定义为体重指数在24至27.4kg/m²之间和≥27.5kg/m²，将中心性肥胖定义为男性腰围≥90cm，女性腰围≥80cm。采用酶联免疫吸附测定（ELISA）法测量血浆HMW脂联素浓度。
结果
女性（n = 677，2.47μg/mL）的血浆HMW脂联素浓度显著高于男性（n = 404，1.58μg/mL）（P < 0.0001），且与男性（r = 0.28）和女性（r = 0.29）的年龄增长相关。在调整分析中，超重者（男性n = 159，1.26μg/mL；女性n = 227，2.15μg/mL）和肥胖者（分别为男性n = 60，1.31μg/mL；女性n = 82，2.10μg/mL）的血浆HMW脂联素浓度低于正常体重者（分别为男性n = 185，2.07μg/mL；女性n = 368，2.94μg/mL），中心性肥胖者（分别为男性n = 106，1.28μg/mL；女性n = 331，2.12μg/mL）的血浆HMW脂联素浓度低于腰围正常者（分别为男性n = 298，1.74μg/mL；女性n = 346，2.74μg/mL）。在按性别分层、调整混杂因素并分别考虑每个肥胖指标的多元回归分析中，所有肥胖指标均与血浆HMW脂联素浓度显著相关（r = -0.18至-0.31，P < 0.001）。然而，在进一步逐步考虑所有肥胖指标的分层和调整回归分析中，只有腰臀比与男性（r = -0.10）和女性（r = -0.15）的血浆HMW脂联素浓度显著相关（P < 0.05）。
结论
肥胖的人体测量指标，如腰臀比，而非BIA指标，与血浆脂联素浓度独立相关。
