Suicide Related Indicators and Trends in Korea in 2019 / 보건행정학회지

This study aimed to update suicide-related indicators including suicidal ideation, suicide attempts, and the number of suicidal deaths.Based on up-to-date information, we observed the trends of suicide-related indicators. In this study, five data sources were used to observe the trends of suicide-related indicators: Statistics Korea (1983–2019), Korean National Health and Nutrition Examination (KNHANES, ‘07–13, ‘15–19), Korean Community Health Survey (KCHS, ‘08–09, ‘13, ‘17), Korean Wealth Panel Study (KOWEPS, ‘12–19), and Korea Health Panel Survey (KHP, ‘10–13, ‘16-17). The suicide rate, which peaked in 2011, declined until 2017 and then started to rise again from 2018, recording a suicide rate of 26.9 per 100,000 people in 2019. The rate of suicidal ideation estimated based on the recently available data was 4.62% (KNHANES, ‘19), 3.51% (KHP, ‘16), 2.87% (KHP, ‘17), and 1.70% (KOWEPS, ‘19). That of suicide attempt as recent year was 0.43% (KNHANES, ‘19), 0.07% (KOWEPS, ‘19). Annual percentage change of death by intentional self-harm was -2.11% (Statistics Korea), and that of suicidal ideation was -14.7% (KNHANES), -2.5% (KCHS), -10.6% (KOWEPS), and -11.3% (KHP). Annual percentage change of suicide attempt was -5.0% (KNHANES), -4.4% (KCHS), and -11.3% (KOWEPS). The lower the income level, the higher the probability of experiencing suicide ideation and suicide attempts. Considering the recent increase in suicide rate in contrast to the continuing decline in suicidal ideation and suicide attempts, continuous data observation and appropriate policies regarding suicide prevention are needed.

A Study on Regional Differences in Healthcare in Korea: Using Position Value for Relative Comparison Index / 보건행정학회지

Background@#This study aims to measure regional healthcare differences in Korea, and define relatively underserved areas. @*Methods@#We employed position value for relative comparison index (PARC) to measure the healthcare status of 250 areas using 137 indicators in five following domains: healthcare demand, supply, accessibility, service utilization, and outcome. We performed a sensitivity analysis using t-SNE (t-distributed stochastic neighboring embedding). @*Results@#Based on PARC values, 83 areas were defined as relatively underserved areas, 49 of which were categorized as moderate and 34 as severe. The provincial regions with the most underserved areas were Gyeongbuk (16 areas), Gangwon (13), Jeonnam (13), and Gyeongnam (12). @*Conclusion@#This study suggests a relative comparison approach to define relatively underserved areas in healthcare. Further studies incorporating various perspectives and methods are required for policy implications.

Suicide Related Indicators and Trends in Korea in 2018 / 보건행정학회지

Suicide has been a long-standing problem for global public health, along with almost 800,000 deaths from suicide worldwide in 2016, accounting for 1.4% of all deaths. South Korea was ranked first in suicide mortality in 2018 among countries in the Organization for Economic Cooperation and Development. This study aimed to suggest up-to-date information about suicide-related indicators such as the rate of suicidal ideation, suicide attempt, and suicide death, and its trends by applying sampling weight to make it nationally representative. In this study, we used the data sources: Korea National Health and Nutrition Examination (KNHANES, ‘07–13, ‘15–18), Korean Community Health Survey (KCHS, ‘08–09, ‘13, ‘17), Korean Wealth Panel Study (KOWEPS, ‘12–18), Korea Health Panel Survey (KHP, ‘10–13), and Statistics Korea (1983–2017). The rate of suicidal ideation as recent year was 4.73% (KNHANES, ‘17), 6.96% (KCHS, ‘17), 2.29% (KOWEPS, ‘18), and 5.39% (KHP, ‘13). That of suicide attempt as recent year was 0.51% (KNHANES, ‘18), 0.32% (KCHS, ‘17), and 0.15% (KOWEPS, ‘18). Annual percentage change (APC) of suicidal ideation was -15.4% (KNHANES, ‘07–13, ‘15, ‘17), -2.5% (KCHS, ‘08–09, ‘13, ‘17), -10.8% (KOWEPS, ‘12–18), and -10.9% (KHP, ‘10–13). APC of suicide attempt was -4.4% (KNHANES, ‘07–13, ‘15-18), -4.4% (KCHS, ‘08–09, ‘13, ‘17), and -13.6% (KOWEPS, ‘12–18). APC of death by intentional self-harm was -1.25% (Statistics Korea, ‘07–18). All suicide-related indicators were found to be decreasing in the overall from 2009. Individuals with lower income level were more likely to experience suicidal ideation and suicide attempts. Even though suicide rate had been continuously decreasing from its highest point in 2011 (suicide rate: 31.7 per 100,000 population) to 2017 (suicide rate: 24.3 per 100,000 population), it increased again in 2018 (suicide rate: 26.6 per 100,000 population). This information would be grounded on policy implementation for suicide prevention, thus continuous data observation is necessary.

Depressive symptoms in individuals with family members requiring ADL assistance

BACKGROUND@#The number of patients with depressive symptoms worldwide is increasing steadily, and the prevalence of depression among caregivers is high. Therefore, the present study aimed to identify the effects of individuals' caregiving status with respect to their family members requiring activities of daily living (ADLs) assistance on depressive symptoms among those aged 45 or over.@*METHODS@#Data were collected from the 2006-2016 using the Korean Longitudinal Study of Aging surveys. Participants were categorized into three groups based on their caregiving status with respect to family members requiring ADL assistance: whether they provided the assistance themselves, whether the assistance was provided by other caregivers, or whether no assistance was required. We analyzed the generalized estimating equation model and subgroups.@*RESULTS@#A total of 3744 men and 4386 women were included for the analysis. Men who cared for family members requiring ADL assistance had higher depressive symptoms than those with family members who did not require ADL assistance. Among women, participants who had family members requiring ADL assistance that they themselves or others were providing had higher depressive symptoms than those without family members requiring ADL assistance. Subgroup analysis was conducted based on age, job status, regular physical activities, participation status in social activities, and the number of cohabiting generations.@*CONCLUSIONS@#The study results indicated higher depressive symptoms among those with family members requiring ADL assistance and those who care for such family members themselves. This suggests that an alternative to family caregiving is necessary, especially for the elderly, regardless of caregiver sex.

Suicide Related Indicators and Trends in Korea in 2017 / 보건행정학회지

Suicide is a major public health issue that causes over 800,000 deaths each year globally. Korea ranks high in suicide rates, in which around 24.3 per 100,000 individuals are reported to have died by intentional self-harm in 2017 according to Statistics Korea. The aim of this study was to examine the current status and trend of suicide ideation and attempt using data from the following five sources: Korean National Health and Nutrition Examination (KNHANES, ‘07–13, ‘15–17), Korean Community Health Survey (KCHS, ‘08–09, ’13, ’17), Korean Wealth Panel Study (KOWEPS, ‘12–17), Korea Health Panel Survey (KHP, ‘10–13), and Statistics Korea (1983–2017). Suicide ideation and attempts were also further examined based on equalized household income levels. Data published by Statistics Korea were used to show the updated suicide rate and number of deaths by intentional self-harm. The rate of suicide ideation at the recent year was 4.73% (KNHANES, ‘17), 6.96% (KCHS, ‘17), 1.63% (KOWEPS, ‘17), and 5.39% (KHP, ‘13). That of suicide attempts as recent year was 0.71% (KNHANES, ‘17), 0.32% (KCHS, ‘17), and 0.09% (KOWEPS, ‘17). Annual percentage change of suicidal ideation was −15.4% (KNHANES, ‘07–17), −2.5% (KCHS, ‘08–17), −8.6% (KOWEPS, ‘12–17), and −10.9% (KHP, ‘10–13). Annual percentage change of suicide attempts was −4.0% (KNHANES, ‘07–17), −4.4% (KCHS, ‘08–17), and −14.9% (KOWEPS, ‘12–17). Individuals with lower income levels were more likely to experience suicide ideation and attempts. Considering that Korea still shows a high suicide rate despite the continuously decreasing trend of suicide ideation and attempt, continuous observation and appropriate policy implementation regarding suicide related problems are necessary.
