Nationwide prevalence and trends in cigarette smoking among adult men with and without disabilities in South Korea between 2009 and 2017.

OBJECTIVES: Current smoking rates for people with and without disabilities vary among countries. This study analyzed smoking behavior over 9 years in adult South Korean men with disabilities, according to disability severity and type, and in those without disabilities. STUDY DESIGN: This was a cross-sectional study. METHODS: This analysis was conducted using national disability registration data and national general health checkup data for 2009-2017. Age-standardized smoking behaviors were analyzed for each year according to the presence, severity, and type of disability. The odds of current smoking were determined by multivariate logistic regression after adjusting for sociodemographic and clinical variables. RESULTS: The age-standardized smoking rate and average number of cigarettes for men with mild disabilities in the younger age group were 1.16 (43.0 vs 36.8%) and 1.05 (16.1 vs 15.3 cigarettes) times higher than in non-disabled men as of 2017. The highest smoking rate was observed in men with physical disabilities in the younger age. In the older age group, the highest smoking rate was that of men with intellectual or psychological disabilities. CONCLUSION: Smoking behaviors remained poorest in men with disabilities, especially those with mild, physical, and intellectual/psychological disabilities. Public health policies should focus on people with disabilities to promote health, prevent secondary conditions, and reduce health disparities by implementing antismoking health policies.

Longitudinal analysis of anxiety and sleep disorders in the Korean population with disabilities, from 2006 to 2017: Incidence, prevalence, and association with disability type and severity.

BACKGROUND: Individuals with disabilities often face a higher risk of concurrent psychological problems, yet comprehensive assessments of the anxiety and sleep disorders in this population remain limited. This study examined longitudinal trends in the incidence and prevalence of anxiety and sleep disorders among people with disabilities and explored their associations with disability type and severity. METHODS: Utilizing claim data from the National Health Insurance database and the National Disability Registry, which cover the entire Korean population, we estimated the age-standardized incidence and prevalence of anxiety and sleep disorders between 2006 and 2017. Logistic regression was used to analyze the associations between disability type and severity and these disorders. RESULTS: The unadjusted incidence and prevalence of anxiety and sleep disorders were consistently higher among individuals with disabilities during the study period. A significant gap in the prevalence of these disorders persisted between individuals with and without disabilities in both sexes, even after accounting for socioeconomic status and comorbidities. However, the incidence showed mixed results, with some categories of disabilities showing lower likelihood of developing the conditions compared to individuals without disabilities. CONCLUSIONS: Actions should also be taken to identify undiagnosed cases of anxiety and sleep disorders among individuals with disabilities. Moreover, individuals with disabilities who are diagnosed with these disorders should be more actively managed to avert the progression to the chronic stage.
