Associations of dual sensory impairment with incident mobility and ADL difficulty.

ABSTRACT:

Background

There is a dearth of studies examining the associations of objectively measured dual sensory impairment (DSI) with incident mobility and activities of daily life (ADL) difficulty longitudinally.

Methods

Cox proportional hazards models were used to examine the associations of DSI and single sensory impairment (hearing, vision) with incident mobility difficulty (many problems or inability to walk ¼ mile and/or climb 10 steps) and ADL difficulty up to six years of follow-up among 2020 participants of the Health, Aging, and Body Composition Study, a cohort of older adults aged 70-79 years from Pittsburgh, PA and Memphis, TN. Vision impairment (VI) was defined as impaired visual acuity (20/50 or worse on Bailey-Lovie distance test) and contrast sensitivity (<1.3 log units on Pelli-Robson test), and hearing impairment (HI) was defined as pure-tone average in better-hearing ear >25 decibels. Models were adjusted by age, race, sex, education, diabetes, depressive symptoms, hypertension, gait speed from 20-meter walk, global cognition score, prevalent cardiovascular disease, and body mass index.

Results

There were 23% with DSI (n = 459). DSI was associated with increased risk of both incident report of mobility (hazard ratio [HR] = 2.25, 95% confidence interval [CI]: 1.47, 3.43), and ADL difficulty (HR = 2.26, 95% CI: 1.50, 3.40). Neither VI nor HI alone was associated with risk of either outcome.

Conclusions

DSI is associated with increased risk of incident mobility and ADL difficulty. Rehabilitation and adaptive environmental changes for individuals living with DSI may be important to maximize mobility and daily function.

Project description:Vision and hearing impairments are known to increase in middle age. In this study we describe the prevalence of vision impairment and dual sensory impairment in UK adults aged 40-69 years in a very large and recently ascertained data set. The associations between vision impairment, age, sex, socioeconomic status, and ethnicity are reported.This research was conducted using the UK Biobank Resource, with subsets of UK Biobank data analysed with respect to self-report of eye problems and glasses use. Better-eye visual acuity with habitually worn refractive correction was assessed with a logMAR chart (n = 116,682). Better-ear speech reception threshold was measured with an adaptive speech in noise test, the Digit Triplet Test (n = 164,770). Prevalence estimates were weighted with respect to UK 2001 Census data.Prevalence of mild visual impairment (VA >0.1 logMAR (6/7.5, 20/25) and ?0.48 (6/18, 20/60)) and low vision (VA >0.48 (6/18, 20/60) and ?1.3 (6/120, 20/400)) was estimated at 13.1% (95% CI 12.9-13.4) and 0.8% (95% CI 0.7-0.9), respectively. Use of glasses was 88.0% (95% CI 87.9-88.1). The prevalence of dual sensory impairment was 3.1% (95% CI 3.0-3.2) and there was a nine-fold increase in the prevalence of dual sensory problems between the youngest and oldest age groups. Older adults, those from low socioeconomic and ethnic minority backgrounds were most at risk for vision problems.Mild vision impairment is common in middle aged UK adults, despite widespread use of spectacles. Increased likelihood of vision impairment with older age and with ethnic minorities is of concern given ageing and more ethnically diverse populations. Possible barriers to optometric care for those from low socioeconomic and ethnic minority backgrounds may require attention. A higher than expected prevalence of dual impairment suggests that hearing and vision problems share common causes. Optometrists should consider screening for hearing problems, particularly among older adults.

Project description:ImportancePerceived everyday discrimination is a psychosocial stressor linked to adverse health outcomes, including mortality.ObjectiveTo assess the association of vision impairment (VI), hearing impairment (HI), and dual sensory impairments (DSI) with everyday discrimination.Design, setting, and participantsCross-sectional analysis of the Health and Retirement Study 2006 and 2008 surveys, a US population-based survey that included noninstitutionalized adults 51 years and older. Analyses were weighted to account for complex sample design and differential nonresponse. Data were analyzed between October 2019 and November 2019.ExposuresParticipants rated their vision and hearing, using eyeglasses and/or hearing aids if applicable, on a Likert scale (poor, fair, good, very good, and excellent). Sensory impairment was defined as poor or fair ability in the relevant modality, and sensory impairment was categorized as neither sensory impairment (NSI), VI alone, HI alone, and DSI.Main outcomes and measuresPerceived everyday discrimination was measured on the validated 5-question Williams scale (range 0 to 5). Linear regression models estimated differences in discrimination scores by sensory categories, adjusting for age, sex, race, ethnicity, non-US birth, body mass index, relationship status, net household wealth, and number of chronic diseases (among diabetes, hypertension, heart disease, stroke, lung disease, nonskin cancer, and arthritis).ResultsThe sample included 13 092 individuals. After weighting the sample to be representative of the US population, 11.7% had VI alone, 13.1% HI alone, and 7.9% DSI. In the fully adjusted model, participants with VI alone (β [change in discrimination score], 0.07; 95% CI, 0.02-0.13), HI alone (β = 0.07; 95% CI, 0.02-0.11), and DSI (β = 0.23; 95% CI, 0.16-0.29) perceived greater discrimination compared with participants with NSI. The DSI group perceived greater discrimination than VI alone or HI alone.Conclusions and relevanceOlder adults with VI or HI in the United States perceive greater everyday discrimination than older adults with NSI, and those with DSI perceive even more discrimination than those with either VI or HI alone. These results provide insight into the social impact of sensory loss and highlight a need to identify and address reasons for discrimination toward older adults with VI and HI.
