Presence of Teen Clubs and its Association with Clinic Attendance among Adolescents Living with HIV in Tanzania: A Retrospective Cohort Study.

Introduction: Adolescent's living with Human Immunodeficiency Virus (HIV) are widely reported to have poor adherence to antiretroviral therapy (ART) due to stigma and fear of discrimination. A "Teen club" is an adolescent centered intervention designed to reduce social stigma and improve adherence and retention in HIV care. In this study we determined how the availability of teen clubs within routine HIV care and treatment facilities affects adolescents' clinic attendance.

Methods: We conducted a retrospective cohort study using secondary data from routine clinic records on adolescents (10-19 years) who started ART between 2010 and 2016, and had documented clinic visits between March 2017 and September 2017 at HIV care and treatment clinics (CTC) in northern and central Tanzania. Good clinic attendance was defined as attending at least four monthly clinic visits during the 7-month follow-up period. A Poisson model with robust standard errors was used to assess the relationship between presence of a teen club at health facilities and good clinic attendance adjusting for other factors including sex, age at ART initiation, duration on ART, WHO clinical stage and health facility level.

Results: Of the 2839 adolescents, 73.1% had good clinic attendance. Good clinic attendance was independently associated with availability of a teen club at the health facility (aRR=1.16, 95%CI:1.09-1.21) and been on ART for >2 years (aRR=1.15, 95%C1.02-1.30). Adolescents aged 15-19 years during this study were less likely to have good clinic attendance (aRR= 0.93, 95%CI:0.88-0.98) than those aged <15 years. Sex and WHO clinical stage were not associated with good clinic attendance.

Conclusion: Teen clubs improved visit adherence among adolescents in HIV care and treatment. Further qualitative research should be conducted to explore adolescents' perception of teen clubs as well as other enablers to clinic attendance.
