Background This population-based study estimated the health-economic costs of dementia from a societal perspective using nationally representative data from 2015 to 2019 and analysed recent trends in Korea. Methods The prevalence of and mortality due to dementia were calculated using the National Health Insurance claims data and population census. The health-economic burden due to dementia was estimated using a prevalence-based approach, including the number of dementia patients and the number of deaths resulting from dementia during 2015–2019. The health-economic burden was presented separately as the national burden and the burden per capita by summing the direct and indirect costs. Results Between 2015 and 2019, the prevalence of dementia among the elderly aged 65 years or older based on clinical diagnosis increased from 5.9 to 7.3%, with approximately 588000 elderly dementia patients in Korea. The total health-economic cost of dementia increased by about 1.5 times in the last 5 years and was estimated to be about USD 4218 million. Direct costs were 52.0% in 2019, and the proportion has been steadily increasing over the past 5 years; indirect costs accounted for 48.0% of the total burden, mainly from family members and caregivers. The health-economic cost per capita due to dementia was approximately USD 6957. Conclusions The burden of dementia in Korea is expected to considerably increase alongside the elderly population in the future. Health policies addressing the prevention and management of dementia should be prioritised.

The coronavirus disease (COVID-19) pandemic is traumatic and causes a substantial psychological burden on the general public. The aim of the present study is to examine the severity and prevalence of peritraumatic distress among the citizens of Seoul, which conducted preemptive and aggressive social distancing policy before the central government during the early stage of COVID-19. Furthermore, this study aims to explore the associated risk factors for peritraumatic distress, including risk perception, fear, and COVID-19-related experiences. We conducted an online survey to 813 participants at the end of the first wave of COVID-19 in South Korea. Peritraumatic distress inventory (PDI) was used to measure the level of pandemic-related distress. One-third of participants were at risk for the development of clinically elevated peritraumatic distress. The perception of risk, fear of COVID-19, and stigma were significantly associated with elevated levels of distress. Individuals who had poor health, or who spent more than 1 h per day using the media, also expressed a higher level of distress. Moreover, the level of disruption of daily life and financial difficulties due to the COVID-19 pandemic is significantly associated with a higher level of peritraumatic distress. The results of this study highlight the urgent need to develop evidence-based and tailored public mental health interventions, along with various measures to help recovery to daily life.

This study examines the relationship between emotional exhaustion and job satisfaction. We further propose a safety climate and compensation as contextual variables that weaken the effect of emotional exhaustion. Survey data collected from 694 employees of a public hospital provided support for the hypothesized research model. The hierarchical multiple regression results reveal that high emotional exhaustion is negatively related to job satisfaction. In addition, the results suggest that compensation and a safety climate are moderating variables that mitigate the negative effects of emotional exhaustion. The theoretical implications and future directions are discussed.

This study applied the extended parallel process model (EPPM) to investigate the factors affecting people’s preventive behaviors against COVID-19, and thereby, draw relevant policy implications for current and future other epidemics. The EPPM was used to examine the danger control and fear control responses, along with the separate effects of their sub-factors (perceived susceptibility, perceived severity, response efficacy, and self-efficacy) on personal hygiene behaviors, social distancing measures, and fatalism. In total, data from an online survey of 813 adults were analyzed. The results of multiple regression analysis showed a strong effect of self-efficacy on danger control (ß = 0.23 for personal hygiene behaviors, β = 0.26 for social distancing) and fear control responses (ß = -0.13 for fatalism). However, based on the type of control response, the effect of perceived susceptibility and perceived severity, which were the main factors in threat appraisal, was insignificant or marginally significant. Further, a higher perceived severity was associated with higher fatalism in the fear control response (ß = 0.09). Those who were currently employed performed fewer social distancing measures compared to those who did not (ß = -0.11), whereas there was no difference in personal hygiene behaviors. These results suggest that risk communication in emerging infectious disease crises should provide customized information on people who are hard to comply with social distancing. Besides delivering the message of self-efficacy, policies should be implemented to create a social environment in which individuals can practice social distancing without constraints.
