Brief Summary
Birth control pills are the most commonly used method of birth control. The purpose of this research study is to examine whether birth control pills change heart disease risk and how the body handles blood sugar when given to different women.

Outcome Measures
Primary Outcomes (3)
Change From Baseline in Insulin Sensitivity
Insulin sensitivity from Frequently sampled IV glucose tolerance test (FSIVGTT), change from baseline to 6 months. Higher values indicate better insulin sensitivity
Baseline, 6 months
Change From Baseline in Flow-mediated Vasodilatation
Change Flow-mediated Vasodilatation from baseline to 6 months. Higher values indicate less cardiovascular risk
Baseline, 6 months
Change From Baseline in Carotid Intima Media Thickness
Change in Carotid Intima Media Thickness from baseline to 6 months, measured on the right carotid artery, posterior. Lower values indicate better cardiovascular risk profile
baseline, 6 months
Secondary Outcomes (13)
Change From Baseline in Acute Insulin Response to Glucose
Baseline, 6 months
Change From Baseline in Glucose Effectiveness
Baseline, 6 months
Change From Baseline in Disposition Index at 6 Months

Interventions
Ethinyl estradiol 35 mcg and norgestimate 0.25 mg (oral) will be taken as one tablet daily for 21 days per month followed by a 7-day pill-free period per cycle. Duration of the study is for 6 cycles of this birth control pill.
Eligibility Criteria
You may qualify if:
- Premenopausal, regular-cycling women 18-35 years
- Either African-American or Caucasian (African-American and Caucasian women will be BMI-matched)
- non-smoker.
You may not qualify if:
- Diabetes
- Clinically significant pulmonary, cardiac, renal, hepatic, neurologic, psychiatric, infectious, and malignant disease
- Contraindications to oral contraceptive use (history of blood clots, heart attacks or stroke, vascular disease, coagulopathy, prolonged immobilization, breast cancer, migraine head-aches, major surgery within past 6 months, blood pressure \>160/100 mmHg, pregnancy or lactation)
- Use of hormonal contraceptives, glucose-lowering medications, anti-hyperlipidemic, anti-hypertensive or other vasoactive drugs within previous 3 months
