Integrated Care Delivery of HIV Prevention and Treatment in AGYW in Zambia

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.

AGYW will be encouraged to select caregivers who will participate in some of the education sessions. The role of the caregiver is to support AGYW. Primary and secondary outcomes will be reported for AGYW only.

Data collection will use electronic tablets with pre-loaded software and instruments in multiple languages. Voice-enabled components and self-administration options will be available for sensitive questions. Instruments will be pretested with AGYW and caregivers. The study team will abstract data from clinic records with support from the Zambian Ministry of Health, conducting pilot data abstraction and staff training to ensure high-quality data for the study.

Key aspects of the intervention include tailored education modules for AGYW and caregivers, youth clubs led by peer navigators, and integrated wellness clinics offering comprehensive sexual and reproductive health services.

The SHIELD study aims to improve HIV prevention and care for AGYW in Zambia by addressing knowledge, skills, self-efficacy, social support, and healthcare access through a comprehensive, theory-based intervention. By combining education, social support, and improved healthcare services, the researchers hope to make significant strides in reducing HIV transmission and improving health outcomes for adolescent girls and young women in Zambia.
