RESUMO
In order to determine the frequency of hepatitis A in children and adolescents in the cities of Lima, Arequipa, Piura, Cajamarca and Iquitos, a descriptive cross-sectional study which measured serum anti-hepatitis A antibodies from 1,721 children and adolescents aged 1-15 years was performed. The overall frequency of positive serology was 50.5% (95% CI: 48.1 to 52.9), with lower rates for Lima at 37.4% (95% CI: 35.1 to 39.8) and higher rates for Iquitos at 68.7% (95% CI: 63.6 to 73.4). Seropositivity was higher in the group of 10-15 year-olds with 66.1% and in the socioeconomic status group E with 64.6%. We concluded that the cities studied have a pattern of intermediate endemicity. The frequency of hepatitis A was greater in children and adolescents of lower socioeconomic status and older age.

Con el objetivo de determinar la frecuencia de hepatitis A en niños y adolescentes en las ciudades de Lima, Arequipa, Piura, Cajamarca e Iquitos, se realizó un estudio transversal descriptivo para lo cual se midió anticuerpos antihepatitis A en suero de 1721 niños y adolescentes de 1 a 15 años. La frecuencia de serología positiva global fue de 50,5% (IC 95%: 48,1-52,9), siendo menor para la ciudad de Lima con el 37,4% (IC 95%: 35,1û39,8) y mayor para la ciudad de Iquitos con el 68,7% (IC 95%: 63,6-73,4). La seropositividad fue mayor en el grupo de 10 a 15 años con 66,1% y en el nivel socioeconómico del grupo E con el 64,6%. Se concluye que las ciudades estudiadas tienen un patrón de endemicidad intermedio. La frecuencia de hepatitis A fue mayor en los niños y adolescentes de menor nivel socioeconómico y de mayor edad...
