OBJECTIVE
Menopause status may lead to increases of body fat, abdominal obesity, and the incidence of metabolic syndrome (MS). Leptin is an adipokine that is secreted by adipocytes and plays an important role in regulating energy homeostasis and the reproductive system. This study examined the relationship among obesity, MS, and serum leptin levels in pre- and postmenopausal women. METHODS: We divided 168 women who visited St. Vincent Hospital of the Catholic University of Korea in 2006 and 2007 into premenopausal vs. postmenopausal, obese vs. non-obese groups based on their body mass index (BMI) and the presence of MS. We measured serum follicle-stimulating hormone (FSH) level, serum estradiol level, BMI, the waist-hip ratio (WHR) and visceral fat area (VFA), serum fasting glucose, lipid profile, blood pressure, and serum leptin level. RESULTS: Of 56 premenopausal and 112 postmenopausal women, there were 21 (37.5%) premenopausal and 51 (45.5%) postmenopausal women with MS. In the non-obese premenopausal and postmenopausal women, there were positive correlations between FSH, markers of abdominal obesity such as WHR and VFA, and serum leptin after adjusting for BMI in postmenopausal women. In the MS group, only WHR was correlated with the serum leptin level after adjusting for BMI in all groups. CONCLUSION: Increased serum FSH level and abdominal obesity lead to an increased serum leptin level in postmenopausal women. Further studies are needed to clarify the relationship between leptin and the metabolic syndrome, risk of cardiovascular disease in postmenopausal women. |
