Improving contraceptive use among Latina adolescents: A cluster-randomized controlled trial evaluating an mHealth application, Health-E You/Salud iTu.

OBJECTIVE: To evaluate the effectiveness of Health-E You/Salud iTu, a mobile health application (app), on increasing knowledge, self-efficacy and contraception use among Latina adolescents, its impact on visit quality, and app satisfaction. STUDY DESIGN: This study used cluster-randomized controlled trial (CRCT) of 18 school-based health centers (SBHCs). Prior to the visit, intervention participants received the patient-centered contraceptive decision-making support app and controls answered sexual health questions on iPads. Participants completed a previsit questionnaire and 3 follow-up surveys (48 hours, 3-, and 6-months) after the recruitment visit (where intervention participants completed the app). Differences in adolescents' contraceptive knowledge, self-efficacy, and use over the 6-month follow-up were assessed by generalized mixed effects regression models. RESULTS: A total of 1,360 Latina adolescents participated; 57.2% responded to the 48-hour survey, 50.1% to the 3-month, 49.7% to the 6-month, and 42.3% to both the 3- and 6-month surveys. Health-E You users' demonstrated significant increases in pre-post knowledge (p < 0.001). Intervention participants who completed the follow-up survey reported greater increases in mean self-efficacy from baseline (23.2 intervention vs. 22.5 controls) to 6 months (26.1 vs. 23.4; b = 1.58, 95% CI 0.38-2.77, p = 0.01), and greater increases in non-barrier contraceptive use from baseline (29% intervention vs. 30% controls) to 3 months (63% vs. 45%; OR = 3.29, 95% CI 1.04-10.36, p = 0.04) and 6 months (63% vs. 44%; OR = 5.54, 95% CI 1.70-18.06, p = 0.005). Providers and adolescents reported high app satisfaction and stated it improved visit quality. CONCLUSIONS: While data suggest that Health-E You improved outcomes, findings must be interpreted cautiously. Intervention participants had higher baseline sexual activity rates, more recruitment visits for pregnancy testing, emergency contraception or birth control, and lower completion rates of follow-up surveys than controls. IMPLICATIONS: Despite declines in adolescent pregnancy in the United States, Latinas continue to have disproportionately high rates compared to white females. The Health-E You app may be an effective support tool for both adolescents and providers in SBHCs, and possibly other clinical settings, across the country to increase contraceptive use and thereby decrease unintended pregnancies. It could potentially reduce disparities in adolescent pregnancies and create more efficient visit time spent between clients and their providers.

The Association Between Nonbarrier Contraceptive Use and Condom Use Among Sexually Active Latina Adolescents.

PURPOSE: This study aimed to determine the association between use of highly effective methods of nonbarrier contraception and condom use in a sample of Latina adolescents and whether the change to a more effective method of nonbarrier contraception is associated with a change in condom use. METHODS: As part of a larger study, 442 sexually active Latina adolescents aged 14-18 years were surveyed immediately before an appointment with a medical care provider at a school-based health center and 3 months later. Ordinal logistic and linear regression were used in the analysis of cross-sectional and longitudinal data to assess the relationship between patterns of nonbarrier contraception and condom use. RESULTS: The use of all types of nonbarrier methods of contraception was significantly associated with decreased condom use. Change over time from a less effective to a more effective nonbarrier method of contraception was also associated with a decrease in condom use. Greater number of sexual encounters was associated with lower the frequency of condom use. CONCLUSIONS: The use of highly effective methods of nonbarrier contraception was associated with reduced frequency of condom use. This highlights the need to promote condom use concurrently with nonbarrier methods of contraception to improve protection against both pregnancy and STIs.

A Mobile Health Contraception Decision Support Intervention for Latina Adolescents: Implementation Evaluation for Use in School-Based Health Centers.

BACKGROUND: Health care providers are a trusted and accurate source of sexual health information for most adolescents, and clinical guidelines recommend that all youth receive comprehensive, confidential sexual health information and services. However, these guidelines are followed inconsistently. Providers often lack the time, comfort, and skills to provide patient-centered comprehensive contraceptive counseling and services. There are significant disparities in the provision of sexual health services for Latino adolescents, which contribute to disproportionately higher rates of teenage pregnancy. To address this, we developed Health-E You or Salud iTu in Spanish, an evidence-informed mobile health (mHealth) app, to provide interactive, individually tailored sexual health information and contraception decision support for English and Spanish speakers. It is designed to be used in conjunction with a clinical encounter to increase access to patient-centered contraceptive information and services for adolescents at risk of pregnancy. Based on user input, the app provides tailored contraceptive recommendations and asks the youth to indicate what methods they are most interested in. This information is shared with the provider before the in-person visit. The app is designed to prepare youth for the visit and acts as a clinician extender to support the delivery of health education and enhance the quality of patient-centered sexual health care. Despite the promise of this app, there is limited research on the integration of such interventions into clinical practice. OBJECTIVE: This study described efforts used to support the successful adoption and implementation of the Health-E You app in clinical settings and described facilitators and barriers encountered to inform future efforts aimed at integrating mHealth interventions into clinical settings. METHODS: This study was part of a larger, cluster randomized control trial to evaluate the effectiveness of Health-E You on its ability to reduce health disparities in contraceptive knowledge, access to contraceptive services, and unintended pregnancies among sexually active Latina adolescents at 18 school-based health centers (SBHCs) across Los Angeles County, California. App development and implementation were informed by the theory of diffusion of innovation, the Patient-Centered Outcomes Research Institute's principles of engagement, and iterative pilot testing with adolescents and clinicians. Implementation facilitators and barriers were identified through monthly conference calls, site visits, and quarterly in-person collaborative meetings. RESULTS: Implementation approaches enhanced the development, adoption, and integration of Health-E You into SBHCs. Implementation challenges were also identified to improve the integration of mHealth interventions into clinical settings. CONCLUSIONS: This study provides important insights that can inform and improve the implementation efforts for future mHealth interventions. In particular, an implementation approach founded in a strong theoretical framework and active engagement with patient and community partners can enhance the development, adoption, and integration of mHealth technologies into clinical practice.
