The aim of this study was to evaluate the relationship between changes in abdominal fat areas and the baseline serum leptin levels of Japanese obese women during weight reduction. The study was performed on 100 obese female Japanese volunteers. We measured the BMI and abdominal fat areas (visceral, subcutaneous and total) by magnetic resonance imaging and determined the fasting serum leptin levels before and after a 3-month weight reduction program. We examined whether or not a relationship exists between the baseline leptin levels and the subsequent changes in the abdominal fat areas after a weight reduction program. Multiple linear regression analysis was performed to examine the relationship between the baseline leptin levels and changes in abdominal visceral, subcutaneous, and total fat areas, and demonstrated that the baseline leptin level was a significant predictive factor for changes in the abdominal visceral fat area in both pre-and postmenopausal Japanese obese women. We thus concluded the relatively higher baseline leptin levels in Japanese obese women to be associated with a relatively smaller reduction in the amount of abdominal visceral fat after undergoing a weight reduction program.
