RESUMEN

Objetivo Estimar cobertura de vacunación contra hepatitis A en niños de 24 meses y identificar factores associados a falta de vacunación.

Métodos Encuesta en muestra estratificada por estratos socioeconómicos en capitales (2020-2022), con estimación de cobertura e intervalos de confianza del 95% (IC₉₅%) y análisis de factores por la razón de prevalencia (RP) mediante regresión de Poisson.

Resultados En los 31.001 niños, la cobertura de hepatitis A fue del 88,1% (IC₉₅% 86,8%; 89,2%). Em estratos socioeconómicos (A/B), variable padres/tutores inmigrantes se asoció con la ausência de vacunación (RP = 1,91; IC₉₅% 1,09;3,37); en estratos C/D, variables niño amarillo (RP = 4,69; IC₉₅% 2,30;9,57), cuarto orden de nacimiento o más (RP=1,68; IC₉₅% 1,06;2,66), no asistir a guardería/jardín de infancia (RP = 1,67; IC₉₅% 1,24;2,24) y madre con trabajo remunerado (RP = 1,42; IC₉₅% 1,16;1,74) se asociaron la ausência de vacunación.

Conclusión Cobertura de la hepatitis A por debajo del objetivo (95%), sugiriendo considerar las especificidades de los estratos sociales.
