简要总结
The study team will test a multilevel package of interventions to connect adolescent girls and young women (AGYW) with a source of regular care to provide a sustainable platform for successful implementation of regular human immunodeficiency virus (HIV) testing and support for linkage to care, retention in care, and adherence to antiviral treatment. Interventions will include integrated wellness care (IWC) clinics and the SHIELD intervention (Support for HIV Integrated Education, Linkages to care, and Destigmatization) to educate and empower AGYW and their families, and to create community-based youth clubs to foster peer support. A cluster randomized controlled trial will be implemented where AGYW participants, stratified by age group and HIV status, will be randomized based on their residence within the six study clinic catchment areas, into the following intervention arms: no intervention, the SHIELD intervention, and the SHIELD intervention and IWC clinics.
详细描述
The SHIELD intervention aims to improve HIV prevention and care for adolescent girls and young women (AGYW) in Zambia. It is based on social cognitive theory and includes a program for AGYW to increase knowledge, skills, and self-efficacy, as well as a program for family members to increase social support. The intervention also incorporates youth clubs facilitated by peer navigators and integrated wellness clinics (IWC) for sexual and reproductive health services. It will be tailored for five distinct groups based on age and HIV status, with modules covering HIV prevention and treatment, wellness, sexual health, stigma reduction, and healthcare access.
IWC clinics will be established in existing government health facilities, following a model similar to cervical cancer screening clinics. Standard operating procedures (SOPs) will be developed for HIV, HPV vaccination, and sexual and reproductive health services.
Time and motion methodology will monitor AGYW clinic visits to identify areas for improvement. To establish a sampling frame, the study team will identify six clinics in Lusaka, map neighborhoods within the selected clinic catchment areas, and recruit AGYW through household visits by peer navigators.
The HIV-/u cohort will include females aged 10-20 years with self-reported HIV-negative or unknown status. They must not be pregnant or planning pregnancy, be willing to sign a medical records release, plan to reside in the area for 18 months, and not be part of other formative research activities. The study will recruit 1,000 HIV-/u AGYW, with equal numbers in age ranges 10-12, 13-15, and 16-20.
The HIV+ cohort will consist of females aged 16-24 years, diagnosed with HIV within the past 3 years, and meeting the same additional criteria as the HIV-/u cohort. The study will enroll 800 HIV+ AGYW, with equal representation among 16-20 and 21-24 age groups.

研究组 & 干预措施
Control
2 control clinics, and their associated catchment areas, with no intervention at the clinic or community level
SHIELD: Community-based behavioral intervention
2 clinics, and their associated catchment areas, where participants attend modules designed to educate and empower adolescent girls and young women (AGYWs) and their caregivers, along with attendance at community-based youth clubs to foster peer support.
干预措施: SHIELD intervention (Support for HIV Integrated Education, Linkages to care, and Destigmatization) (Behavioral)
SHIELD: Community- based behavioral intervention & IWC Clinic
2 clinics, and their associated catchment areas, where participants and their caregivers receive the Support for HIV Integrated Education, Linkages to care, and Destigmatization (SHIELD) intervention along with the coupled benefits of having an integrated wellness care (IWC) clinic within health facilities where adolescent girls and young women (AGYWs) can receive sexual and reproductive health services, including HIV testing and treatment, family planning, sexually transmitted disease screening and treatment, and human papilloma virus (HPV) vaccination.
