Abstract The article reviews the various steps necessary to successfully complete a national epidemiological study focusing on the incidence and prevalence of sensorineural hearing loss in children. With particular emphasis on funding, equipment, staff, test sites, procedures and data processing/analysis, the authors provide a step-by-step description of the difficulties encountered in attempting major epidemiological research in a developing nation. Results suggest that the incidence of sensorineural losses in children in Costa Rica is between 1.50-1.63 per 1000 live births. The authors conclude with a discussion of the strengths and weaknesses of various approaches to assisting nations as they develop services.

L’article examine les diverses étapes nécessaires à la réussite d’une étude épidémiologique nationale portant sur l’incidence et la prédominance de la surdité de perception chez les enfants. En mettant l’accent particulièrement sur le financement, l’équipement, le personnel, les sites et procédures d’essai, et le traitement et l’analyse des données, les auteurs offrent une description détaillée des difficultés que l’on doit surmonter lorsqu’on veut entreprendre une importante recherche épidémiologique dans un pays en voie de développement. Les résultats portent à croire que l’incidence de surdité de perception chez les jeunes costaricains se situe entre 1,50 et 1,63 par 1 000 naissances vivantes. Les auteurs terminent en étudiant les atouts et faiblesses de diverses méthodes employées pour aider les pays à élaborer les services.
