Filter by:This study tests two posters that teach people about contraception: one designed by the Centers for Disease Control (CDC), and one designed by the researchers. The investigators hypothesize that the new poster will have more increased (1) contraceptive knowledge, (2) willingness to use effective contraception, and (3) perceived pregnancy risk than the CDC poster. This study will expand useful knowledge because contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk have been shown to affect women's likelihood of using contraception. If the investigators learn how to increase these factors, the investigators could theoretically reduce women's risk of unplanned pregnancy. The investigators will test this hypothesis by recruiting N=1000 women to complete an online survey using Amazon Mechanical Turk. These women will complete a survey that will first measure their initial contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk. Then women will randomly be shown one of the two posters. Then, the investigators will measure their contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk again. The investigators will use statistical tests (a t-test) to find out whether there are significant changes in these three outcomes for either of the posters, and whether one poster does a better job of changing these outcomes than the other.
This trial evaluated folic acid supplementation after oral administration of the ethinyl estradiol + levonorgestrel + folic acid (0.02 mg + 0.10 mg + 0.4 mg) coated tablet (Level-Fol® Biolab Sanus Farmacêutica, São Paulo, Brazil) in healthy female volunteers, based on statistical comparisons of folate levels in erythrocytes. Its safety and tolerability was also evaluated.
This is an exploratory prospective study investigating if addition of a COX-2 inhibitor can increase efficacy of ulipristal in disrupting ovulation at peak fertility.
This study explores reasons why adolescents choose to receive a nexplanon implant and remove a Nexplanon implant. Nexplanon is provided as part of the standard of care on the University of Chicago mobile health unit. This study explores reasons for implantation and removal of Nexplanon on this mobile health unit.
A prospective, non-inferiority study to evaluate the pharmacokinetic effect of topiramate on serum Etonogestrel (ENG) levels in contraceptive implant users.
This study will evaluate the frequency of ovulation and cervical mucus quality of HIV-infected women on efavirenz (EFV)-based antiretroviral therapy (ART) using either a single etonogestrel (ENG) implant or two ENG implants for at least one year.
This is a randomized controlled trial comparing lay Lady Health Workers (Lay Health Workers) with Family Welfare Workers (Clinically- trained Health Workers) on quantitative measures of safety and effectiveness of Depo Provera and Sayana Press provision in a clinic setting. This comparative trial will test the non-inferiority hypothesis that Lady Health Workers are just as competent as clinically-trained Family Welfare Workers in screening and counseling first-time injectable users. These first time users will also be randomly assigned to receive intramuscular or subcutaneous injections of DMPA.
This is a single-arm, open-label, Phase III study in approximately 100 sites in the United States (US) over seven cycles of use in women aged 18 to 35 years who are at risk of pregnancy.
The goal of this study is to identify the thoughts and perceptions of pharmacy access to hormonal contraception among rural women and pharmacists. This will be key in order to address concerns or perceived barriers in order to inform the implementation of this program.
This study entails a quasi-experimental, mixed-methods (i.e., complementary quantitative and qualitative) outcome evaluation to assess the efficacy of the Reaching Married Adolescents (RMA) Interventions developed and implemented by Pathfinder International to increase contraception use and contraception use intentions among married adolescent girls ages 13-19 in three rural districts of the Dosso region of Niger. Intervention models (gender-synchronized household visits and small groups) will be tested using a randomized 4-arm outcome evaluation design; Arm 1 will receive household visits, Arm 2 will receive small groups; Arm 3 will receive household visits plus small groups, and Arm 4 will serve as the control group and will not receive any intervention. The quantitative component will consist of collecting quantitative baseline, 16-months follow-up, and 27-months survey data from randomly selected married adolescent girls (n=1200) and their husbands (n=1200) who are participating in each Arm of the study. Qualitative elements will include ethnography at two time points and semi-structured in-depth interviews half way through intervention implementation. A costing and cost effectiveness analysis will also be conducted to evaluate which intervention provides the largest gain in the primary outcomes for each dollar spent.
