Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Distribution of contraceptive method chosen | Distribution of methods (%) chosen at baseline enrollment, by method and stratified by Long-Acting Reversible Contraception (LARC: intrauterine device and implant) and non-LARC (depotmedroxyprogesterone acetate (DMPA), oral contraceptive pill (OCP), vaginal ring, transdermal patch). | Baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Method Continuation | % of women using each method at 6, 12-, 24, and 36 months post-enrollment. Hazard rates via survival analysis comparing LARC and non-LARC methods. | 6-month, 12 month, 24-month, and 36-month | 
| Method Satisfaction | % of women very or somewhat satisfied with method at 12, 24, and 36 months of use. Comparison of all methods and stratified by LARC and non-LARC methods. | 12-month, 24-month, 36-month | 
| Teen Pregnancy Rates | Number of pregnancies per participants 15-19 years of age. We will calculate an annual rate for each year from 2007-2013 and also calculate a rate for the cohort followed for 1 year, 2 years, and 3 years. | 1-year, 2-year, 3-year | 
| Repeat Abortion Rates | Number of abortions among participants 15-44 with a history of abortion. We will calculate an annual rate for each year from 2007-2013 and also calculate a rate for the cohort followed for 1 year, 2 years, and 3 years. | 1-year, 2-year, 3-year | 
| Sexually transmitted infection rates | Baseline prevalence rates (number positive divided by number tested) for chlamydia, gonorrhea, and trichomonas. 1-year incidence rates for the same infections among those who tested at 1-year. | Baseline and 12-months |
