Like the rest of Canada, the city of Ottawa is facing the "age wave"--a rapidly growing on-rush in the number of seniors. Indeed, Ottawa-Carleton has one of the fastest growing senior populations in the province of Ontario. About 70,000 of the residents, or 11 per cent of the population, are over 65, and this number is expected to increase to 15 per cent by the year 2011.
In a collaborative study from Washington, D. C., and Johannesburg, South Africa, the clinical, laboratory, and immunologic features of 64 black patients (25 male, 39 female) who had pernicious anemia were studied. Mean age at diagnosis was 53 +/- 20 years (mean +/- SD); 29.6% of the patients were under 40 years of age, and 14% were 30 years of age or younger. This suggests that there may be an earlier age of onset of pernicious anemia amongst blacks than the reported age incidence in whites. Serum anti-intrinsic factor blocking antibodies were found in 25 of 37 patients tested (67.5%). There was a significantly higher incidence of the antibody in women (85%) than in men (50%) (P < 0.01).
