Abstract

The purpose of this study was to describe the prevalence of hearing loss (HL), vision loss (VL), and dual sensory loss (DSL) in Canadians 45–85 years of age. Audiometry and visual acuity were measured. Various levels of impairment severity were described. Results were extrapolated to the 2016 Canadian population. In 2016, 1,500,000 Canadian males 45–85 years of age had at least mild HL, 1,800,000 had at least mild VL, and 570,000 had DSL. Among females, 1,200,000 had at least mild HL, 2,200,000 had at least mild VL, and 450,000 had DSL. Among Canadians 45–85 years of age, mild, moderate, and severe HL was prevalent among 13.4 per cent, 3.7 per cent, and 0.4 per cent of males, and among 11.3 per cent, 2.3 per cent, and 0.2 per cent of females, respectively. Mild and moderate, or severe VL was prevalent among 19.8 per cent and 2.4 per cent of males, and among 23.9 per cent and 2.6 per cent of females, respectively. At least mild DSL was prevalent among 6.4 per cent of males and 6.1 per cent of females.

RÉSUMÉ

L'objectif de cette étude était de décrire la prévalence de la perte auditive (PA), de la perte visuelle (PV) et de la double perte sensorielle (DPS) chez les Canadiens âgés de 45 à 85 ans. L'audiométrie et l'acuité visuelle ont été mesurées. Différents niveaux de sévérité de la déficience ont été décrits. Les résultats ont été extrapolés à la population canadienne de 2016. En 2016, 1 500 000 hommes canadiens âgés de 45 à 85 ans avaient au moins une légère PA, 1 800 000 avaient au moins une légère PV et 570 000 avaient une DPS. Chez les femmes, 1 200 000 avaient au moins une légère PA, 2 200 000 avaient au moins une légère PV et 450 000 avaient une DPS. Parmi les Canadiens âgés de 45 à 85 ans, les cas de PA légère, modérée ou sévère étaient fréquentes chez 13,4 pour cent, 3,7 pour cent et 0,4 pour cent des hommes, et chez 11,3 pour cent, 2,3 pour cent et 0,2 pour cent des femmes, respectivement. La PV légère et modérée, ou sévère, était prévalente chez 19,8 pour cent et 2,4 pour cent des hommes, et chez 23,9 pour cent et 2,6 pour cent des femmes, respectivement. Une DPS au moins légère était prévalente chez 6,4 pour cent des hommes et 6,1 pour cent des femmes.
