Health and Socio-Demographic Factors Affecting Happiness Among Korean Adults with Moderate and Severe Disabilities: A National Survey-Based Study.

Background and Objectives: This study identified health-related factors that affect the happiness of Korean adults with disabilities based on the disability level. Materials and Methods: Data of 7581 adults with disabilities aged 20 or older were collected from the 2023 Survey on the Status of Persons with Disabilities. The collected data were analyzed using frequency and multivariate logistic regression analyses. Results: Among individuals with moderate disability, males were less happy than females. Those with elementary school or lower education levels were less happy than those with college or higher education levels. Those who experienced stress, sadness and despair, suicidal thoughts, or discrimination were less happy than those who did not. In contrast, married individuals were happier than unmarried individuals. Those who exercised, went out alone, engaged in paid work, or participated in social activities were happier than those who did not. Among individuals with severe disabilities, males were less happy than females. Those with lower levels of education were less happy than those with higher levels of education. Those who experienced stress, sadness and despair, suicidal thoughts, suicide attempts, difficulty in communication, or discrimination were less happy than those who did not. Those who perceived their body as very thin were less happy than those who perceived it as very obese. Those who suffered from chronic disease were less happy than those who did not. In contrast, those aged 20-29 were happier than those aged 80 years or older. Married individuals were happier than unmarried ones. Those who exercised, went out alone, engaged in paid work, or participated in social activities were happier than those who did not. Conclusions: Factors affecting the happiness of Korean individuals with disabilities differ depending on the disability degree. Therefore, health policies, plans, and support measures must be established based on the disability degree to support daily physical activities, along with health services facilitating physical activity.
