ABSTRACT
OBJECTIVE:
This study was performed to prove the relationship between serum leptin level and bone mineral density of lumbar spine, femur neck and bone markers in postmenopausal Korean women.METHODS:
We measured serum leptin, serum osteocalcin, urine deoxypyridinoline levels and bone mineral density of lumbar spine, femur neck in 88 premenopausal and 118 postmenopausal women who visited St. Vincent Hospital of Catholic University of Korea from March 1st, 2007 to December 31th, 2007.RESULTS:
Statistically significant correlation was shown between serum leptin level and body mass index (BMI) in both premenopausal (r= 0.343, P<0.0001) and postmenopausal women (r=0.360, P<0.0001). And no significant correlation was observed between serum leptin level and bone mineral density (BMD) of lumbar spine and femur neck in premenopausal women (r=0.013, P=0.107 and r=0.004, P=0.425, respectively), but in postmenopausal women, there was a positive correlation between serum leptin and lumbar spinal BMD (r=0.085, P=0.02). But after the adjustment with age and BMI, the serum leptin and BMD of lumbar spine did not showed a significantly correlation in the same group (r=0.088, P=0.939). Also, no significant correlations were observed between serum leptin level and serum osteocalcin and urine deoxypyridinoline in premenopausal (r=0.004, P=0.566 and r=0.002, P=0.707, respectively) and postmenopausal women (r=0.026, P=0.096 and r=0.000, P=0.933, respectively).CONCLUSIONS:
In our study, there is no significant correlation between serum leptin level and bone mineral density and bone markers in premenopausal and postmenopausal Korean women. Our own data would suggest that leptin has both negative and positive effects in bone mass regulation. Furthermore, larger clinical studies are necessary to clarify leptin's role to assess the contribution of the central and peripheral role of leptin in the overall maintenance of bone turnover.
