Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Distribution of contraceptive method chosen | Baseline | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Method Continuation | 6-month, 12 month, 24-month, and 36-month | % 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. |
| Method Satisfaction | 12-month, 24-month, 36-month | % 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. |
| Teen Pregnancy Rates | 1-year, 2-year, 3-year | 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. |
| Repeat Abortion Rates | 1-year, 2-year, 3-year | 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. |
| Sexually transmitted infection rates | Baseline and 12-months | 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. |
