Effect of Health Shocks on Poverty Status in South Korea: Exploring the Mechanism of Medical Impoverishment

Food Insecurity, Healthcare Utilization, and Healthcare Expenditures: A Longitudinal Cohort Study

Objective: This study examines the longitudinal association between household food insecurity and healthcare utilization and expenditure. Methods: A multi-wave longitudinal cohort study was conducted using the 2008-2019 and 2021 waves of the Korean Welfare Panel Study. The baseline data included participants aged ≥19 years with valid responses to the food insecurity and healthcare questionnaires in the 2008 wave (n = 12,166). Healthcare outcomes encompassed outpatient visits, inpatient admissions, days hospitalized, and personal healthcare expenditure. Random effects Poisson and linear regressions were estimated. Results: Severe food insecurity was associated with a higher incidence rate of outpatient visits (IRR, 1.14; 95% CI, 1.12-1.17), days of hospitalization (IRR, 1.18; 95% CI, 1.13-1.22), and inpatient admissions (IRR, 1.40; 95% CI, 1.18-1.65). Moderate food insecurity was associated with 10.4% (β = -0.11; 95% CI, -0.14 to -0.07) or 238,276 KRW reductions in personal healthcare expenditures in the subsequent year. Conclusion: Household food insecurity was linked to increased healthcare utilization and reduced personal healthcare expenditure among Korean adults. Our findings present opportunities to identify target populations for healthcare policies and interventions.

Measurement and Decomposition of the Health Poverty of Rural Residents in China

Narrowing the health gap and promoting health equality is the key to effectively blocking the intergenerational transmission of rural poverty. Previous studies have mainly focused on the relationship between health and poverty, but assessments of health poverty are lacking, especially with regard to the health poverty of rural residents. Based on China's large sample household survey data, this study uses the Alkire-Foster (AF) method to measure and decompose the health poverty of rural residents. The results show that the health poverty of Chinese rural residents greatly improved from 2016 to 2018. However, significant regional differences exist with regard to the level of health poverty. The marginal contribution of economic poverty alleviation is diminishing; the equalization of health services and security has shifted to a policy focus. Community environmental management has also become an important aspect of health poverty governance, and individual health literacy and behavior have played an important role in endogenous poverty alleviation. Ultimately, this paper offers some insightful policy implications. This study extends the multidimensional poverty measurement system and reveals the relationship between health poverty and regional economic and social development. The findings also enhance the understanding of the health poverty of rural residents in developing countries.

What fragile factors hinder the pace of China's alleviation efforts of the poverty-stricken population? A study from the perspective of impoverishment caused by medical expenses

OBJECTIVE

China has made remarkable achievements in poverty alleviation. However, with the change in economic development and age structure, the population stricken by poverty due to medical expenses and disability accounted for 42.3 and 14.4% of the total poverty-stricken population, respectively. Accordingly, it is crucial to accurately pinpoint the characteristics of people who are about to become poor due to illness. In this study, we analyzed the incidence of impoverishment by medical expense at the provincial, family, and different medical insurance scheme levels to identify the precise groups that are vulnerable to medical-related poverty.

METHOD

Data were extracted from the Fifth National Health Service Survey in China in 2013 through a multi-stage, stratified, and random sampling method, leaving 93,570 households (273,626 people) for the final sample. The method recommended by World Health Organization (WHO) was adopted to calculate impoverishment by medical expense, and logistic regression was adopted to evaluate its determinants.

RESULTS

The poverty and impoverishment rate in China were 16.2 and 6.3% respectively. The poverty rate in western region was much higher than that of central and eastern regions. The rate of impoverishment by medical expense (IME) was higher in the western region (7.2%) than that in the central (6.5%) and eastern (5.1%) regions. The New Cooperative Medical Scheme (NCMS) was associated with the highest rate (9.1%) of IME cases. The top three diseases associated with IME were malignant tumor, congenital heart disease, and mental disease. Households with non-communicable disease members or hospitalized members had a higher risk on IME. NCMS-enrolled, poorer households were more likely to suffer from IME.

CONCLUSION

The joint roles of economic development, health service utilization, and welfare policies result in medical impoverishment for different regions. Poverty and health service utilization are indicative of households with high incidence of medical impoverishment. Chronic diseases lead to medical impoverishment. The inequity existing in different medical insurance schemes leads to different degrees of risk of IME. A combined strategy to precise target multiple vulnerabilities of poor population would be more effective.
