According to their WG, the subjects were divided into 2 risk groups: WG <88 cm (Group increased risk [IR], n=48) or WG >/= 88 cm (Group high risk [HR], n=42). The subjects in each group were equally assigned to receive standard or low dose of E2/NETA (2 mg E2/1 mg NETA, or 1 mg E2/0.5 mg NETA). Accordingly, the 2 groups were divided into 4 subgroups. Serum leptin levels (SLLs), body weight/height, waist/hip girth, BMI and waist-to-hip ratio were evaluated before and after therapy.RESULTS: In the Group IR, WG decreased significantly only in low dose subgroup. In the Group HR, both standard and low dose subgroups had a significant reduction in WG. Those who had WG >/= 88 cm showed more reduction than those who had WG <88 cm in response to both doses of E2/NETA, insignificantly. Basal SLLs had a significant correlation with body weight, BMI and WG.CONCLUSION: Oral standard and low dose E2/NETA reduce WG and attenuate the BMI- and waist girth- related risk of cardiovascular and metabolic diseases in postmenopausal women.
