Resumo: | In view of the importance of knowing the prevalence and incidence rates of a disease to learn about its behavior and control at the collective level, a study was undertaken to determine the occurrence of hanseniasis among the clients of health agencies and to expore the use of this methodology for estimating the epidemiologic "iceberg" of the disease, i. e., the total number of cases including those that are not officially reported. The city of Taubaté in the Paraíba Valley, State of S. Paulo, Brazil, was chosen for the study. All clients aged 15 years or older were screened regardless of variables such as sex, age, social condition or marital status. The study was based on what is known about the populational distribution of the disease and the characteristics of health services. In view of the local peculiarities of operationalization (e.g., identity of the different clientelles, availability of offices, hours of greatest flux), the sampling process used was simple randomization. The patients with active disease detected, 40 of the 10,013 persons examined, correspond to a prevalence of 3.99/1000, whith a confidence interval (at the 5% level of reliability) of 3,365 to 4,625/1000, indicating that the minimum estimated increase of prevalence is of the order of 52% and the maximum estimated increase is of the order of 109%. The indeterminate form of the disease predominated among the patients (35.00%), and this predominance was even more explicit when the patients were classified as registered or new cases: in this latter category, the indeterminate form reached 56.53% and its distribution by age range was dose to that observed in the officially recorded data, as verified by comparing observed cases with expected cases calculated from population indicators. As to sex ratio, a was predominance of males was observed. |

As to sex ratio, a was predominance of males was observed. Dada a importância das taxas de prevalência e incidência de uma moléstia para conhecimento de seu comportamento e planejamento de seu controle, em nível do coletivo, procedeu-se a estudo na cidade de Taubaté, Vale do Paraíba, SP (Brasil) da ocorrência da hanseníase em clientela de agências de saúde com o objetivo de explorar o emprego desta metodologia para estimar o "iceberg" epidemiológico da doença (i.e., o número total de casos, incluindo os existentes, mas não oficialmente registrados). Foram averiguados clientes com idade igual ou superior a quinze anos, independentemente de variáveis pessoais ( como sexo, idade, condição social, estado civil), pois admitiu-se ser conhecida a distribuição populacional da doença e as características dos serviços. Consideradas as peculiaridades locais (v.g. identidade das diferentes clientelas, disponibilidade de consultórios, horários de maior fluxo), o processo de amostragem utilizado foi o da casualização simples. Os doentes detectados em atividade, 40 em 10.013 pessoas examinadas, corresponderam ao índice de prevalência de 3,99/1.000, com intervalo de confiança (ao nível de 5% de confiabilidade) variando de 3.365 a 4.625/1.000, o que significa que o acréscimo mínimo estimado da prevalência é da ordem de 52% e máximo de 109%. Houve predomínio, entre os doentes, da forma indeterminada (35,0%) mais explicitamente quando são eles estratificados em registrados os casos novos: nesta categoria, a forma indeterminada atingiu 56,5%. Sua distribuição por faixa etária não se distanciou da observada com os dados de registro oficial, segundo se constatou pelo cotejo dos casos observados e esperados, calculados a partir dos indicadores populacionais; quanto à proporção sexual, registrou-se predomínio de elementos do sexo masculino.
