Abstract
HIV stigma as a barrier to retention in HIV care has not been well-studied outside the United States. We conducted a case–control study in Lima, Peru to examine this issue. Cases were out-of-care for ≥12 months (n = 66) and controls were recruited from patients in active care presenting for a clinic visit (n = 110). A previously validated HIV stigma scale with four domains was used. Associations between being out-of-care and each stigma domain were assessed using multivariable logistic regression. Stigma scores were highest for disclosure concerns. Modest associations were found for greater disclosure concerns (OR 1.16; 95 % CI 0.99, 1.36) and concerns with public attitudes (OR 1.20; 95 % CI 1.03, 1.40). Enacted stigma and negative self-image showed non-linear associations with being out-of-care that plateaued or declined, respectively, at higher levels of stigma. The threshold effect for enacted stigma warrants further exploration, while disclosure concerns may be especially amenable to intervention in this population.
Resumen
El rol del estigma social asociado al VIH, como una barrera para la retención en el cuidado de VIH, no ha sido bien estudiado fuera de los Estados Unidos. Para examinar este problema, se realizó un estudio de casos y controles en Lima, Perú. Los casos fueron aquellos pacientes que estuvieron fuera del cuidado para VIH por ≥12 meses (n = 66) y los controles aquellos que se encontraban bajo cuidado activo para el VIH (n = 110). Se utilizó una escala para estigma en VIH previamente validada con cuatro dominios. Las asociaciones entre estar fuera del cuidado y cada dominio de estigma fueron evaluadas mediante una regresion logistica multivariable. Los puntajes más altos de estigma fueron para la preocupacion sobre divulgacion de estatus. Se encontraron asociaciones modestas para la preocupacion de divulgación de estatus (OR 1,16; 95 % CI 0,99, 1,36) y la preocupacion por las actitudes publicas (OR 1,20; 95 % IC 1,03 a 1,40). El estigma establecido y la auto-imagen negativa mostraron asociaciones no lineales con estar fuera del cuidado. Estas se estabilizaron o se redujeron, respectivamente, con niveles más altos de estigma. El efecto umbral del estigma declarado merece una mayor exploración, mientras que la preocupacion de divulgación de estatus puede ser un foco de especial atencion en esta población.
