The purpose of this study was to determine how vision problems affect health status. The information was collected in 1990 from 2,249 household heads and spouses over 50 years of age during an annual survey of a nationally representative sample that was adjusted for attrition and nonresponse. Vision problems were defined as "trouble seeing (even with glasses or contact lenses)." Health status was measured principally with the Medical Outcomes Study Short-Form 36. Regression analyses found a significant relationship between "trouble seeing" and each of five health-status domains. We conclude that it may not be appropriate to require specific functional limitations as a precondition for cataract surgery and that instruments for measuring functional disabilities related to vision should include more general questions.

The association of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) with functional status in the general Medicare population are not well established. This study examined patient-reported survey data linked with Medicare claims to describe the burden of these vision-threatening retinal diseases (VTRDs) among Medicare beneficiaries. Medicare Current Beneficiary Survey data linked with Medicare Fee-for-Service claims data from 2006 to 2018 were used in a nationally representative retrospective pooled cross-sectional population-based comparison study.

Background: Little is known about the self-perceived level of disability of stroke survivors in the community. We aimed to characterise Health-related quality of life (HRQoL) 1 year after stroke and investigate how sociodemographic and stroke-related factors and medical adherence explain the self-perceived level of disability in a Korean stroke population.
Methods: This was a multicentre cross-sectional study.

Purpose: To determine if vision impairment (VI) is associated with food insecurity among the United States (US) adults.
Methods: This is a cross-sectional study of US adults ≥18 years below a threshold of 150% poverty from the National Health Interview Survey (NHIS), years 2011-2018. Outcome measures included food insecurity status, based on response to the NHIS adult (10-item) food insecurity tool, either as a binary (food secure or insecure) or ordinal (high, marginal, low, and very low) variable.

Cochlear Center for Hearing and Public Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, USA.
Background And Objectives: In the United States, up to two-thirds of older adults have hearing loss. Untreated hearing loss can have significant health outcomes, yet less than 20% of adults with hearing loss use hearing aids. In this study, we examined potential factors associated with hearing aid use, including detailed measures of health status, access to care, patient engagement, and technology use, in a nationally representative sample of Medicare beneficiaries.
