Item Open Access Cardiovascular Health Disparities among Older Adults in South Korea(2020) Lee, ChiyoungThe number of older adults in South Korea has increased faster than in any other countries. Along with this trend, the increasing burden of cardiovascular disease among this population is of growing national concern. Central to this concern is a highly disproportionate burden of the disease observed among individuals with a low socioeconomic position.
Older adults with a low socioeconomic position in South Korea are indeed a marginalized population who have been exposed to decades of socioeconomic disadvantages due to Korea’s unique history. They have also been unfavorably affected by the socioeconomic support and healthcare system and experienced widening disparities in access to healthcare services, all of which may lead to greater disparities in cardiovascular health.
In Western countries, where cardiovascular disease is the leading cause of death and health disparities among older adults, researchers have consistently provided in-depth and evidence of changing disparities. They have suggested strategic solutions for policy and healthcare professionals to decrease the detrimental influences of socioeconomic position on health for this group. However, few studies have been conducted on disparities in cardiovascular health among older adults based on socioeconomic position in South Korea. Therefore, the purpose of this dissertation is to explore disparities in cardiovascular health among older adults according to socioeconomic position in South Korea.
This dissertation is organized into five chapters. Chapter 1 introduces the overall research agenda. Chapter 2 provides a systematic review of the literature on socioeconomic disparities in cardiovascular health among Korean adults. Based on the Chapter 1 and the findings of the systematic review, the purposes of data-driven chapters are constructed to address the following aims. First, Chapter 3 will examine time trends in socioeconomic disparities in cardiovascular health over the past decade among older adults in South Korea. Second, Chapter 4 will investigate the role of material, behavioral, psychological, and social-relational factors in the explanation of disparities in cardiovascular health among older adults in South Korea. Particularly in this dissertation, health disparities are defined as differences in health between two or more socioeconomic groups within a population.
Item Open Access Impact of Dementia on Incidence and Severity of Postoperative Pulmonary Complications Following Hip Fracture Surgery Among Older Patients.(Clinical nursing research, 2023-11) Tsumura, Hideyo; McConnell, Eleanor S; Xue, Tingzhong Michelle; Wei, Sijia; Lee, Chiyoung; Pan, WeiPostoperative pulmonary complications (PPCs) are the leading cause of death following hip fracture surgery. Dementia has been identified as a PPC risk factor that complicates the clinical course. By leveraging electronic health records, this retrospective observational study evaluated the impact of dementia on the incidence and severity of PPCs, hospital length of stay, and postoperative 30-day mortality among 875 older patients (≥65 years) who underwent hip fracture surgery between October 1, 2015 and December 31, 2018 at a health system in the southeastern United States. Inverse probability of treatment weighting using propensity scores was utilized to balance confounders between patients with and without dementia to isolate the impact of dementia on PPCs. Regression analyses revealed that dementia did not have a statistically significant impact on the incidence and severity of PPCs or postoperative 30-day mortality. However, dementia significantly extended the hospital length of stay by an average of 1.37 days.Item Open Access The #StopAsianHate Movement on Twitter: A Qualitative Descriptive Study(International Journal of Environmental Research and Public Health, 2022-04-01) Cao, Jiepin; Lee, Chiyoung; Sun, Wenyang; De Gagne, Jennie CEvidence-based intervention and policy strategies to address the recent surge of race-motivated hate crimes and other forms of racism against Asian Americans are essential; however, such efforts have been impeded by a lack of empirical knowledge, e.g., about racism, specifically aimed at the Asian American population. Our qualitative descriptive study sought to fill this gap by using a data-mining approach to examine the contents of tweets having the hashtag #StopAsianHate. We collected tweets during a two-week time frame starting on 20 May 2021, when President Joe Biden signed the COVID-19 Hate Crimes Act. Screening of the 31,665 tweets collected revealed that a total of 904 tweets were eligible for thematic analysis. Our analysis revealed five themes: “Asian hate is not new”, “Address the harm of racism”, “Get involved in #StopAsianHate”, “Appreciate the Asian American and Pacific Islander (AAPI) community’s culture, history, and contributions” and “Increase the visibility of the AAPI community.” Lessons learned from our findings can serve as a foundation for evidence-based strategies to address racism against Asian Americans both locally and globally.
