Background. Tere is an increase in dual sensory impairment (DSI) (hearing and visual) with increase in elderly population. Most
causes of DSI among elderly are treatable. Tis study determines the prevalence and characteristics of dual sensory impairment
among elderly of a rural community. Material and Methods. A cross-sectional study conducted among 175 rural elderly. Visual
acuity for distant vision was measured using Snellen E chart. Hearing ability was measured using pure tone audiometry. Results.
Te prevalence of hearing impairment was 72% and that of visual impairment was 48%. Te overall prevalence of DSI among the
study subjects was 17.7% and 32.6% depending on whether traditional pure tone average or high-frequency pure tone average was
used to defne moderate or worse degree of hearing impairment. DSI prevalence increased signifcantly with increase in age. DSI
was higher among widow/ers and illiterates, who did not have any source of income and those who were fnancially dependent on
others compared to their counter groups. Conclusion. Prevalence of DSI is high among community dwelling rural Indian elderly.
Individuals with DSI produce unique challenges in rehabilitation. A team approach at primary health care level is necessary to
diagnose and rehabilitate elderly thereby enabling them to easily lead an independent life.
1. Introduction
Hearing and visual ability are key aspects of functioning
among the elderly. Hearing and visual impairments among
elderly have been studied extensively as single sensory
impairments, but dual sensory impairment (DSI) among
them is less well understood. Studies have proven that indi-
viduals with DSI have more difculty in performing activities
of daily living and instrumental activities of daily living [1–
3] compared to individuals with single sensory impairment.
In comparison with a single sensory impairment, DSI is
associated with more depressive symptoms [4], lower health
related quality of life [5], and also increased risk of mortality
[6].
Older age is a well known risk factor for sensory impair-
ments. Elderly proportion in India according to 2011 census
is 8.1% and is expected to rise to 17% by the year 2025
[7, 8]. Te special features of Indian elderly population which
is a challenge are a majority (80%) of them being in the
rural areas, large percentage (30%) being in below poverty
line, feminization of the elderly population, and increase
in the number of the oldest age group (≥ 80 years) [8, 9].
Geriatric medical care difers from usual medical care in
shifing the focus to preservation of function and improving
the quality of life rather than treating and curing specifc
diseases. Increasing elderly population will eventually lead to
increase in the prevalence of DSI in India.
Various studies demonstrate that the prevalence rate of
DSI among elderly ranges from 6.5 to 35.0 percent [1, 4–
6, 10–14]. Tere is complexity associated with defning and
understanding DSI as it is determined by the defnitions
for the respective single sensory impairments. Most stud-
ies are from developed countries, are hospital based, and
use traditional pure tone average (PTA) to classify hearing
