Study Description

Brief Summary

Oral contraceptives (OCs) are the most widely used method of reversible birth control. However, the long-term cardiovascular safety of the widely used low-dose OCs (ethinyl-estradiol < 50 mcg) is still debated. Although cardiovascular events are rare in young women whether they use OCs or not, the risks of myocardial infarction and ischemic stroke are increased among users of OCs who have conventional cardiovascular risk factors such as use of tobacco, diabetes or hypercholesterolemia. However, the risk of cardiovascular events in OC users with emerging cardiovascular risk factors (such as obesity and the metabolic syndrome) have not been investigated. Recently, the metabolic syndrome has been linked with the risk of cardiovascular disease. The syndrome is a clustering of risk factors in a single individual, and its underlying cause may be insulin resistance. Whether the metabolic syndrome predicts a higher cardiovascular risk in OC users has not been studied. This is a critical problem because the metabolic syndrome is prevalent in 24% of adults. Until the cardiovascular risks in users of OC are clearly defined, the appropriate use of OC with the least harm would not be possible.

The investigator's long-term goal is to understand the best way to prevent and treat cardiovascular disease in women. The objective of this particular project is to obtain pilot data on the extent to which the metabolic syndrome and obesity affects glucose metabolism and cardiovascular risks in women taking OCs. The researchers hypothesize that women with metabolic syndrome and obese women will have worsened glucose metabolism and elevated cardiovascular risks associated with OC use, when compared to normal weight women without the metabolic syndrome. Results of this study will clarify the risk factors for cardiovascular events in women taking OCs, and will serve as pilot data for a National Institutes of Health (NIH) proposal. Once the cardiovascular risk factors of OC users are understood, clinicians can make better informed decisions about contraceptive choices for their patients.

Outcome Measures

Primary Outcome Measures

  1. Changes in Insulin Sensitivity Associated With Oral Contraceptive (OC) Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    Insulin sensitivity was assessed by frequent sampling intravenous glucose tolerance test (FSIVGTT).

Secondary Outcome Measures

  1. Changes in Lipid Profile Compared Associated With OC Use Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    The lipid profile is assessed through blood sample analysis for low-density lipoprotein (LDL), Triglycerides and high-density lipoprotein (HDL).

  2. Inflammatory Marker Changes, High Sensitive C-reactive Protein (Hs-CRP) and Adiponectin, Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    Inflammatory markers are assessed through blood analysis for C-reactive protein (hs-CRP) and adiponectin.

  3. Changes in Estrogen Metabolites (Plasma) Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

  4. Changes in Waist-to-Hip Ratio Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    Waist-to-hip ratio is assessed through calculated ratio of waist and hip circumference.

  5. Inflammatory Marker Changes (MCP-1) Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    Inflammatory marker is assessed through blood analysis for Monocyte chemotactic protein-1 (MCP-1).

  6. Changes in Blood Pressure Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

  7. Changes in Body Mass Index (BMI) Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    Body Mass Index is a calculation of height and weight: kg/m²

  8. Changes in Waist Circumference Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

  9. Inflammatory Marker Changes, Soluble Vascular Cell Adhesion Molecule (sVCAM) and Soluble Intercellular Adhesion Molecule (sICAM), Associated With OC Use Compared Among (1) Obese Women and (2) Lean Women [Baseline and 6 months]

    These inflammatory markers are assessed through blood analysis of Soluble Vascular Cell Adhesion Molecule (sVCAM) and soluble intercellular adhesion molecule (sICAM).

Exclusion Criteria:
  1. Diabetes mellitus by fasting glucose or a 2-hour oral glucose tolerance test (OGTT);

  2. Clinically significant pulmonary, cardiac (including but not limited to ischemic heart disease, stable/unstable angina, and congestive heart failure), renal, hepatic, cholestatic, neurologic, psychiatric, infectious, and malignant disease (other than melanoma skin cancer);
