Rim, Lee, and Lee: Disparities of Socio-Demographic Factors between Visually Disabled People and Other Disabled People: KNHANES III



To identify the disparities of socio-demographic factors between visually disabled people and other people with disabilities.


The fourth Korea National Health and Nutrition Examination Survey (KNHANES III) is a nationwide survey. The present study included 25,125 people who completed the KNHANES III. For analysis, the participants were divided into 3 groups: subjects without disabilities, subjects with disabilities but without visual disabilities, and subjects with visual disabilities. The gender, age, monthly house income, occupation, education, residential area, and health insurance were investigated. Multivariate logistic regression analysis was used to determine the most differentiating factor.


Visually disabled people were proportionally older (40 to 64 years), were male, living in a non-metropolitan area except Seoul/Pusan/Gyunggi compared to other disabled people and also had a higher proportion of the above factors, as well as lower education compared to non-disabled people.


Socio-demographic factors showed disparities in visually disabled people and people with other disabilities. Ophthalmologists should understand these disparities and be involved in establishing policies to reduce the disparities. Ophthalmologists also need to provide holistic and comprehensive medical care using the Blindness is Preventable! Korea Foundation for the Prevention of Blindness, consultation with social work teams in hospitals and other institutions, as well as evaluating the visual impairment.
