Resumo: | A sample of 1,288 inhabitants of Salvador, Bahia, Brazil, were submitted to the determination of anti-HBs using radioimmunoassay procedure, and analysed according to age, sex and income. Overall prevalence of anti-HBs was 11,8%. ranging from 6,7% among children aged less than three years old to 26,1% among those aged 30 years and older. Males presented prevalence of anti-HBs similar to female individuals, and those with a higher income showed frequencies of anti-HBs greater than those with a lower income level. The following conclusions were drawn: The high prevalence of anti-HBs observed among children suggests early contact with hepatitis B virus, possibly due to vertical transmission and intrafamiliar dissemination of the disease; the frequency of anti-HBs increases with age; the lower prevalence of anti-HBs among those with low income suggests that this group may present higher prevalence of carriers of the hepatitis B virus surface antigen. |

Prevalence of antibody to hepatitis B virus in an urban population of northeast Brazil Prevalência de anticorpos contra o vírus da hepatite B em população urbana do nordeste brasileiro A sample of 1,288 inhabitants of Salvador, Bahia, Brazil, were submitted to the determination of anti-HBs using radioimmunoassay procedure, and analysed according to age, sex and income. Overall prevalence of anti-HBs was 11,8%. ranging from 6,7% among children aged less than three years old to 26,1% among those aged 30 years and older. Males presented prevalence of anti-HBs similar to female individuals, and those with a higher income showed frequencies of anti-HBs greater than those with a lower income level. The following conclusions were drawn: The high prevalence of anti-HBs observed among children suggests early contact with hepatitis B virus, possibly due to vertical transmission and intrafamiliar dissemination of the disease; the frequency of anti-HBs increases with age; the lower prevalence of anti-HBs among those with low income suggests that this group may present higher prevalence of carriers of the hepatitis B virus surface antigen. Um grupo de 1.288 indivíduos, residentes em Salvador, Bahia, Brasil, foi examinado para a determinação de anti-HBs, utilizando-se a técnica do radioimunoensaio. Os resultados foram analisados de acordo com a idade, o sexo e o nível de renda. Uma prevalência de anti-HBs de 11,8% foi observada, variando de 6,7% nas crianças com idade inferior a três anos, a 26,1% para aqueles com idade superior a 30 anos. A prevalência de anti-HBs foi similar em indivíduos do sexo masculino e feminino. Aqueles com nível de renda mais alto tiberam prevalência de anti-HBs maior que o grupo de renda baixa. Dos resultados conclui-se: a alta prevalência de anti-HBs em crianças sugere o contato precoce com o vírus da hepatite B, possivelmente relacionado com a transmissão vertical e a disseminação intraíamiliar do vírus; a freqüência de anti-HBs aumentou com a idade; a baixa prevalência de anti-HBs entre aqueles com baixo nível sócio-econômico sugere que neste grupo pode ser alta a prevalência de portadores do vírus B da hepatite.
