Un projet d'evaluation de la prevalence des maladies non transmissibles liees a la nutrition et aux habitudes toxiques est en cours d'elaboration en Polynesie francaise. La methodologie utilisee, bien que tres lourde, a deja ete mise en oeuvre avec succes dans les Etats insulaires du pacifique Sud, ayant un mode de vie traditionnel ou transitionnel. Les auteurs ont voulu evaluer, par un sondage d'opinion utilisant la methode des quotas, le niveau d'acceptabilite de l'enquete projetee dans la population tres urbanisee et occidentalisee du 'grand Papeete' afin d'obtenir des informations essentielles quant a la faisabilite du projet. Les resultats favorables (75% des sujets sondes participeraient, 19,5% refuseraient, 5,5% hesiteraient) doivent etre interpretes en fonction du caractere multiethnique de la Polynesie francaise, et des limites de la methode de sondage employee.A prevalence study on non communicable diseases related to nutrition, alcoholism and tabagism is planned in French Polynesia. The methodology used, although complicated, has been successful in insular states of the South Pacific with either traditional or transitional ways of life. Acceptability level of the study in the urban area of Papeete (Tahiti) has been tested by a public opinion poll using the quota method in order to obtain valuable information on feasibility of the project. The public opinion poll showed that 75% of people would participate, 19.5% would be reluctant and 5.5% would hesitate. The good results must be carefully interpreted with regards to the multi-ethnic structure of French Polynesian population, and to the limits of the quota method.
