Multifactorial determinants of lost to follow-up in antiretroviral therapy: evidence from a case-control study in Mexico.

ABSTRACT:

Background

Loss to follow-up (LTFU) remains a major challenge in achieving sustained HIV care. Understanding individual and structural factors influencing disengagement is essential to improve retention, particularly in low- and middle-income settings. This study aimed to identify predictors of LTFU among adults receiving antiretroviral therapy (ART) in western Mexico.

Methods

A case-control study was conducted among adults with HIV treated at a tertiary hospital. Cases met the national definition of LTFU (≥ 90 days beyond the expected clinic visit or pharmacy refill), while controls were retained patients during the same period. A total of 919 participants were included (148 LTFU, 771 retained). Multivariable logistic regression identified factors associated with LTFU.
