O conhecimento desse par\u00e2metro epidemiol\u00f3gico \u00e9 importante pela influ\u00eancia eventual da enfermidade na qualidade de vida, bem como o risco de complica\u00e7\u00f5es. OBJETIVO: Estudar a preval\u00eancia de pirose na popula\u00e7\u00e3o adulta na cidade de Pelotas, RS. DELINEAMENTO: Estudo transversal de base populacional. PACIENTES E M\u00c9TODOS: Foram inclu\u00eddos indiv\u00edduos a partir de 20 anos, residentes na zona urbana da cidade. Utilizou-se amostragem por conglomerados em 40 setores censit\u00e1rios do Instituto Brasileiro de Geografia e Estat\u00edstica. Question\u00e1rios padronizados e pr\u00e9-codificados foram aplicados aos participantes. Realizou-se controle de qualidade aplicando-se question\u00e1rios simplificados em 10% das pessoas inclu\u00eddas na amostra. A codifica\u00e7\u00e3o e a entrada de dados atrav\u00e9s do programa Epi-Info foram realizadas duas vezes, com o intuito de diminuir os erros de consist\u00eancia. A an\u00e1lise dos dados foi realizada atrav\u00e9s do programa SPSS, onde foram feitas compara\u00e7\u00f5es entre a preval\u00eancia de pirose em rela\u00e7\u00e3o \u00e0s vari\u00e1veis demogr\u00e1ficas atrav\u00e9s das raz\u00f5es de preval\u00eancias, intervalos de confian\u00e7a a 95% e do teste do qui-quadrado. RESULTADOS: Entre as 1.263 pessoas inclu\u00eddas no estudo, encontraram-se taxas de preval\u00eancias de pirose de 48,2%, 32,2% e 18,2% para o \u00faltimo ano, m\u00eas e semana, respectivamente. Todas as formas do desfecho pirose estavam associadas com o sexo feminino, de maneira estatisticamente significativa. Contudo, n\u00e3o foi encontrada associa\u00e7\u00e3o com rela\u00e7\u00e3o \u00e0 idade. CONCLUS\u00d5ES: As elevadas preval\u00eancias encontradas neste estudo devem chamar a aten\u00e7\u00e3o para assist\u00eancia m\u00e9dica a estes indiv\u00edduos, particularmente ao fato de que est\u00e3o expostos a eventuais complica\u00e7\u00f5es da doen\u00e7a do refluxo gastroesof\u00e1gico.<\/jats:p>","DOI":"10.1590\/s0004-28032003000100007","type":"journal-article","created":{"date-parts":[[2005,4,15]],"date-time":"2005-04-15T10:20:40Z","timestamp":1113560440000},"page":"31-34","source":"Crossref","is-referenced-by-count":9,"title":["Preval\u00eancia
