Abstract
Objectives: As part of a larger study of polychlorinated dibenzodioxin (PCDD) and dibenzofuran (PCDF) pollution, to describe and compare Aboriginal and non-Aboriginal residents’ recalled diets.
Methods: We surveyed a stratified random sample aged 25 to 64 years: forest products mill employees (n=84), Aboriginal reserve residents (n=78), and other residents (n=80). We administered a questionnaire on intake of fish/seafood, wild game and plants, domesticated animal meat and eggs, dairy products, vegetable oils and cereals; age, gender, childbearing, lactation, residence and smoking. We measured height and weight.
Results: Reserve residents ate less seafood, but more fish roe, eulachon grease, smoked salmon, clams and sea urchins, more deer organs, hamburger meat, pork, fried chicken, and hotdogs, but less rabbit, beef steaks/roasts, high-fibre cereals, potato chips, bread, cheese and milk.
Conclusions: We cannot yet quantify PCDD and PCDF intakes. The wild food consumption data are unique and may be useful for risk assessments in the target population and similar communities.
Résumé
Objectifs: Dans le cadre d’une étude plus générale de la pollution par les dibenzodioxines polychlorées (PCDD) et les dibenzofurannes polychlorés (PCDF), décrire et comparer les régimes alimentaires que se rappellent avoir consommés tant les autochtones que les non autochtones.
Méthodes: Nous avons interrogé un échantillon aléatoire stratifié de personnes âgées de 25 à 64 ans: des employés des usines de produits de la forêt (N = 84), des résidents autochtones vivant dans les réserves (n = 78), ainsi que d’autres résidents (n = 80). Nous leur avons demandé de répondre à un questionnaire sur leur consommation de poisson/produits de la mer, gibier et plantes, viande provenant d’animaux d’élevage et oeufs, produits laitiers, huiles végétales et céréales; leur âge, leur sexe, s’ils ont eu des enfants, si les femmes ont allaité, leur lieu de résidence et s’ils fument. Nous avons mesuré le poids et la taille des individus.
Résultats: Les résidents des réserves consomment moins de produits de la mer mais davantage d’oeufs de poisson, de graisse d’eulakane, de saumon fumé, de grosses palourdes et d’oursins, d’organes de cerf, de viande hâchée, de porc, de poulet frit et de hotdogs, mais moins de lapin, de rôtis/steaks de boeuf, de céréales à haute teneur en fibres, de croustilles de pomme de terre, de pain, de fromage et de lait.
Conclusions: Il n’est pas encore possible de quantifier l’ingestion de PCDD et de PCDF. Les données relatives à la consommation d’aliments non industriels sont uniques en leur genre et peuvent être utiles pour évaluer les risques dans la population ciblée ainsi que dans des communautés similaires.
