Abstract
in English, French

Objective: A retrospective study was conducted to compare age- and sex-specific rates of hospital admission of the elderly in Ontario for five influenza seasons from 1988-1993 for pneumonia, congestive heart failure and chronic respiratory disease.

Results: Significant increases in admissions were found for pneumonia in each influenza season for both sexes. Admissions were significantly increased for congestive heart failure for the oldest males in all years; and for four of five years for the youngest two age groups of males. For females significant increases in admissions occurred in the oldest two age groups in each influenza season; and for three of five seasons for the youngest age group. For chronic respiratory disease, significant increases in admissions were found for each influenza season for all years for the two youngest age groups of males and females.

Conclusion: The impact of influenza is substantial in terms of morbidity in the elderly.

Objectif: On a mené une étude rétrospective pour comparer en Ontario, durant cinq saisons grippales (de 1988 à 1993), les taux d’hospitalisation par âge et par sexe des personnes âgées pour cause de pneumonie, d’insuffisance cardiaque globale et de maladie respiratoire chronique.

Résultats: On a constaté des augmentations importantes des pneumonies, chez les deux sexes, durant chaque saison grippale. Les hospitalisations pour insuffisance cardiaque globale ont augmenté de façon importante toutes les saisons chez les hommes les plus âgés et quatre saisons sur cinq chez les hommes des deux groupes les moins âgés. Chez les femmes, il y a eu augmentation importante des hospitalisations au cours de chaque saison grippale pour les deux groupes les plus âgés et trois saisons sur cinq pour le groupe le moins âgé. En ce qui concerne les maladies respiratoires chroniques, il y a eu d’importantes augmentations des hospitalisations en saison grippale chaque année pour les deux groupes les moins âgés, hommes et femmes confondus.

Conclusion: La grippe a un effet marqué sur la morbidité des personnes âgées.
