“…The results from the decomposition analyses suggest that contributions from older age groups to the observed inequalities became greater, implying that older adults can experience increasing burdens of economic deficiency and obesity-related health issues. Considering the rapid aging of the population and the disproportionately increasing rate of poverty among old adults in Korea [68], policy interventions need to be developed to facilitate weight control for older adults.…”

Obesity is a prominent global public health challenge as its prevalence has grown. Even though the increase in prevalence of obesity in Korea has been relatively low, it is expected to continually increase in the next several years, leading to social and economic burdens. This study aimed to assess socioeconomic inequalities in obesity among Korean adults. Using nationally representative survey datasets, the concentration index (CI) and decomposition of the CI were used to capture and quantify obesity-related inequalities from 1998 to 2015. The results suggested that pro-poor inequalities in obesity existed in Korea, indicating that obesity was more concentrated among individuals with lower income. In a gender-stratified model, obesity was more concentrated among women with lower income and men with higher income, showing that the trend and magnitude of inequalities in obesity each vary by gender. The decomposition approach revealed that, over the past 17 years, the main contributors to the existing inequalities were higher education and higher income levels. These findings suggest that comprehensive and multifaceted interventions at the local and national levels should be considered to address the identified income- and education-related barriers with respect to obesity among Korean adults.

“…22 Moreover, the poverty rate among older adults in Korea is approximately 3.5 times higher than the poverty rate of the remainder of the population (14.6%). 23 Previous research has suggested that poorer senior citizens were more likely to suffer from mental illness, providing grounds for a direct association between poverty and suicide risk. [24][25][26][27][28] Thus, our study investigated the impact of poverty on suicide risk among older adults using a relatively large and nationally representative dataset.…”

Objectives The present study evaluated suicide risk within 1 year after discharge among older adults with stroke as a function of depression onset. Method We used the Korean National Health Insurance Service‐Senior cohort data and included first discharged patients with a stroke as the principal diagnosis. The comparison group was selected by a 1:2 case‐control propensity score matching for age, sex, Charlson comorbidity index, and diagnosis year between 2005 and 2012. Suicide deaths were measured by code for causes of death from Statistics Korea, and the main outcome was suicide death within 1 year following discharge. An adjusted hazard ratio (AHR) of suicidal risk was measured using a Cox proportional hazard model. Results In the total sample of 128 286 older adults (aged 63‐114 years), the higher suicidal risk was examined for stroke patients vs the comparison group (AHR = 1.4; 95% confidence interval [CI], 1.1‐1.8). Stroke patients with depression had an increased suicide risk (AHR = 2.9; 95% CI, 1.8‐4.8) but only for poststroke depression (AHR = 4.1; 95% CI, 1.8‐9.5). Pre and poststroke depression suicidality (AHR = 4.8; 95% CI, 2.1‐11.1) was also higher when compared to stroke patients without depression. Conclusions Poststroke patients are at increased suicidal risk during 1 year following discharge. Furthermore, patients who were diagnosed with depression after a stroke are more likely to commit suicide than stroke patients without depression. This suggests a necessity for early suicide preventive intervention for stroke patients while considering depressive symptomology.

“…Old age, especially ≥70 years, was a critical factor for ID deaths in Korea, which could be attributed to biological susceptibility to IDs, but might also be ascribed to the socioeconomic vulnerability of the elderly. For instance, Korea's relative poverty rate (proportion of population with incomes below 50% of the median income) for the elderly has been around 45%, over three times higher than the OECD and national averages [21]. Among the elderly, the rate was even higher among those who were older, lived alone, female, and less educated [21].…”

We aimed to describe the infectious disease (ID) mortality trends and evaluate age–period–cohort (APC) effects on ID mortality in Korea. Using cause-of-death and census population estimates data from 1983–2017, age-standardized ID mortality trends were investigated by joinpoint regression analysis. The APC effects on ID mortality were estimated using intrinsic estimator models. The age effect showed a J-shaped concave upward curve. Old age, especially ≥70 years, was a critical factor for ID deaths. Similar to the W-shaped period curve, ID mortality rapidly decreased due to economic development and the expansion of health coverage in the 1980s, decelerated with increasing inequality, surged due to the 1997 economic crisis, and has gradually increased since the mid-2000s. The cohort effect showed an inverted U-shape. The increasing cohort effect due to the deterioration of living standards led to a decreasing trend after the independence of Korea. Notwithstanding the slowdown during the 1950–1953 Korean War, educational expansion, economic growth, fertility reduction, and the improvement of ID-related policies might have led to a continued decline among the cohorts born since the 1960s. Diverse socioeconomic events may have influenced ID mortality trends in Korea via period and cohort effects. Policies to reduce the growing burden of ID deaths should be further improved.
