The menopause transition is associated with increased risk for weight gain and a shift toward storing fat in the belly region, which may increase risk for cardiovascular disease and diabetes. The study will determine whether the stress hormone cortisol contributes to this shift.
The menopause transition is associated with increased risk for weight gain and a shift toward storing fat in the belly region, which may increase risk for cardiovascular disease and diabetes. The stress hormone cortisol is known to promote the accumulation of belly fat, and there is evidence that low estrogen is associated with higher cortisol levels. The first aim of the study is to determine whether low estrogen levels in premenopausal and early postmenopausal women increase cortisol levels in the blood and in fat tissue. When estrogen level decreases at the time of menopause, there is an in…
Inclusion Criteria: Volunteers will be healthy peri/postmenopausal women who are willing and able to undergo the proposed hormone manipulation and study procedures. Women will be at least 6 months but not more than 7 years past the last menstrual period (i.e., late perimenopausal or early postmenopausal) with FSH \>30 IU/L. We will make a major effort to ensure that the women enrolled in this study come from all races and ethnicities and a wide range of socioeconomic and educational levels. Women will be excluded for the reasons listed below. Exclusion Criteria: * abnormal vaginal bleeding…
GnRH antagonist will be given once for premenopausal women (12-week intervention) and twice for postmenopausal women (24-week intervention)
Estrogen patches will be worn by those randomized to the Estradiol arms in both premenopausal and postmenopausal groups. Patches will be applied weekly and will be worn for the for entirety of the intervention (12 or 24 weeks).
Placebo patches will be worn by those randomized to the placebo arms in both premenopausal and postmenopausal groups. Patches will be applied weekly and will be worn for the for entirety of the intervention (12 or 24 weeks).
Postmenopausal women randomized to the placebo injection arm will receive two placebo drug injections of normal saline (24-week intervention)
