Circulating levels of leptin, nesfatin-1 and kisspeptin in postmenopausal obese women

The roles of leptin, nesfatin-1 and kisspeptin in the regulation of food intake and/or reproduction are well known; however, the interactions between these hormones remain unclear, especially in humans. The aim of this study was to determine the roles of leptin, nesfatin-1 and kisspeptin in pre- and postmenopausal obese and non-obese women. The study included 83 women who were divided into four groups based on menopausal status and body mass index. The leptin level was significantly higher in the obese women than in the non-obese women (p < 0.05), but did not differ significantly between pre- and postmenopausal women (p > 0.05). The nesfatin-1 and kisspeptin-1 levels did not differ significantly between any of the study groups (p > 0.05). The present findings show that nesfatin-1 and kisspeptin levels are not affected by obesity or menopausal status.
