About this trial
This is an interventional treatment trial for Anorexia Nervosa focused on measuring estrogen, anxiety, amenorrhea, eating disorders
Eligibility Criteria
Inclusion Criteria (AN):
- Previous diagnosis of recent AN with BMI of <18.5 (within past year)
- Current BMI > 19.0 and < 23.0 kg/m2
- Amenorrhea or oligomenorrhea
Inclusion Criteria (Healthy Controls):
- BMI > 19 < 23 kg/m2
- Taking hormone-based contraceptives for a period of one month or more
- Eating disorders symptom scores within one standard deviation of healthy controls
Exclusion Criteria (AN):
- Any medical or psychiatric problem requiring urgent medical or psychiatric attention, including acute suicidality
- History of breast cancer, deep vein thrombosis, pulmonary embolism, myocardial infarction or stroke, diabetes, liver disease, known thrombophilic disease
- Currently taking estrogen or progesterone medication
- Tobacco use greater than 1 pack per week
- Use of St. John's Wort, Phenobarbital, phenytoin, carbamazepine, rifampin, and dexamethasone can all decrease plasma estrogen level because they are CYP3A4 inducers. Cimetidine, erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice as these may increase plasma estrogen, potentially increasing the presence of side effects
- Pregnant, lactating or unwilling to use appropriate birth control (which may include abstinence) to prevent pregnancy for the duration of study participation (i.e. up to 4 weeks)
- Allergy to estradiol or medroxyprogesterone or ingredients in food items used for test meals
- Undiagnosed, abnormal vaginal bleeding
Exclusion Criteria (Healthy Controls):
- Ever diagnosed with an Eating Disorder
- Any medical or psychiatric problem requiring urgent medical or psychiatric attention, including acute suicidality
- Pregnant, lactating or unwilling to use appropriate birth control (which may include abstinence) to prevent pregnancy for the duration of study participation (i.e. up to 4 weeks)
- Food allergies to items in the test meal

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Estrogen
Arm Description
AN participants receive a course of transdermal estradiol treatment.
Outcomes
Primary Outcome Measures
Electrodermal skin conductance activity (EDA) during a test meal
Meal-related anxiety will be estimated from EDA recordings during a 90 minute test meal session pre- and post-treatment (day 1 and day 21). EDA will be reported as the rate of peaks (>0.02 microsiemens) per second and the average skin conductance level (in microsiemens).
Secondary Outcome Measures
Heart rate variability during a test meal
Variability in heart rate will be measured by the variation in interpeak (beat-to-beat) interval during the 90 minute test meal session pre- and post- treatment (day 1 and day 21).
Subjective ratings of anxiety
Visual analog scales will be used to assess self-report anxiety at multiple points (time 0 min, 5 min, 10 min, 20 min, 30 min, 50 min, 70 min and 90 min) during the 90 minute test meal session pre- and post-treatment (day 1 and day 21).
Salivary cortisol concentration during a test meal
The concentration of salivary cortisol will be assessed at multiple points (time 0 min, 5 min, 10 min, 20 min, 30 min, 50 min, 70 min and 90 min) during the test meal session. Test meals occur twice during the entire length of the study on day 1 and day 21. The cortisol response will be reported as area under the curve.
