摘要
Objectives: There is increasing evidence suggesting that adiponectin plays a role in the regulation of bone metabolism. Design and methods: This was a cross-sectional study of 34 post-menopausal women with and 37 without osteoporosis. All subjects had body mass index (BMI), bone mineral density (BMD), total-, high molecular weight (HMW)-adiponectin and their ratio, osteoprotegerin (OPG), a marker of bone resorption (beta CTX) and formation (P1NP) measured. Results: We observed a positive correlation between BMI and BMD (r = 0.44, p<0.001). When normalised for BMI, total-, HMW-adiponectin concentrations and HMW/total-adiponectin ratio were significantly lower in obese compared to lean subjects but there was no difference between those with or without osteoporosis. There were significant negative correlations between HMW/total-adiponectin ratio and BMI (r = -0.27, p = 0.030) and with OPG (r = -0.44, p<0.001). Conclusions: Our data suggests that there is no significant difference in the circulating concentration of fasting early morning total-or HMW-adiponectin in post-menopausal women with or without osteoporosis. The correlation between HMW/total-adiponectin ratio and OPG may indicate that adiponectin could influence bone metabolism by altering osteoblast production of OPG thereby affecting osteoclasts mediated bone resorption.
