研究室紹介
Professor Seul Ki Choi's research lab focuses on public health and health disparities, with a strong emphasis on health equity, mental health, and lifestyle-related health outcomes among vulnerable populations. The lab investigates the impact of healthcare policy—particularly Medicaid expansion—on cancer screening and mortality disparities in the U.S., while also exploring dietary behaviors, anthropometric status, and mental health among North Korean defectors resettling in South Korea. Additionally, the lab evaluates digital health tools, such as mobile apps for dementia care, to improve health information access and quality of care. These interdisciplinary efforts aim to inform policy and intervention strategies for underserved and marginalized communities.

15OBJECTIVES: We estimated the impact on cancer disparities in US states that have chosen or not chosen to expand Medicaid since passage of the Patient Protection and Affordable Care Act. METHODS: Data came from the 2013 Uniform Data System for colorectal and cervical cancer screening rates among patients of federally qualified health centers (FQHCs); the 2012 Behavioral Risk Factor Surveillance System for colorectal, cervical, and breast cancer screening rates; and the US Cancer Statistics (2007-
본 연구는 서울시 중고등학생 1,813명을 대상으로 간식섭취 실태를 조사하기 위해 섭취 간식의 종류, 섭취 시간, 구매 장소, 함께 먹은 사람을 조사하여 분석하였다. 분석 결과는 다음과 같다. 1. 연구 대상자들은 하루 평균 2.8가지의 간식을 섭취하였으며, 여학생이 남학생보다 간식 섭취 가짓수가 유의하게 많았다(p < 0.001). 대상자들이 가장 많이 섭취한 간식은 귤과 과자류였다. 연령별, 성별로 다빈도 간식에 차이가 있었다. 2. 대상자의 절반 이상이 하루 1~3가지 간식을 먹는 것으로 나타났으며, 9.3%는 하루 동안 간식을 전혀 먹지 않았다고 응답하였다. 식품군별 가장 많이 섭취한 간식은 기타 음식류와 과일이었으며, 저녁식사 전에 간식을 섭취한 대상자가 가장 많았다. 대상자 집단별로 섭취 간식 가짓수(p < 0.05) 와 다빈도 간식 식품군에 차이가 있었다(p < 0.001). 점심식사 전과 저녁식사 전에는 여학생이 남학생에 비해 간식 섭취자의 비율이 높았으며, 각 시간대
This study reviewed the content of mobile applications (apps) providing Alzheimer's disease or related dementias (ADRD) information and assessed quality of the apps. Characteristics, content, and technical aspects of 36 apps in the U.S. Google Play Store and App Store were coded, and quality of the apps was evaluated using the Mobile Application Rating Scale. Caregiving (62.1%) and disease management (55.6%) content was frequently provided. Few apps had an app community (8.3%) or a reminder func
Among North Korean adolescent and young adult defectors, anxiety and depression were associated with lower HRQoL. Therefore, it is needed to develop strategies to screen for mental health and intervene to reduce anxiety and depression during their early resettlement stage.
North Korean defectors who settle in South Korea have experienced severe food shortage and transition of food environment which could affect their health status. However, little is known about their anthropometric measurements and dietary intake after settlement in South Korea. The purpose of this study is to compare anthropometric measurements and dietary intake between North Korean young adults who defected to South Korea and those of South Koreans. We hypothesized that North Korean young adul

The purpose of this study was to investigate snacking behavior in adolescents. We selected one middle school and one high school in 11 school districts in Seoul. The subjects were 1,813 students (904 boys and 909 girls) in 21 schools (11 middle schools and 10 high schools). Subjects reported their snacking behavior: snack frequency, snack type, snack time, with whom to eat snack, place to purchase snack. The subjects were classified into four groups by gender and schooling. The mean snack freque
Literacy plays an important role in Alzheimer’s disease and related dementias (ADRD); however, less is known about how literacy is being used and defined in ADRD studies. This study reviewed terminology being used to describe types and definitions of literacy and instruments used to assess literacy in ADRD research. Among the 219 studies retrieved from 3 databases, 50 met our inclusion criteria. Literacy terms used in ADRD studies varied: literacy ( n = 28), health literacy ( n = 9), and dementi
Prostate cancer (PrCA) is the most common cancer affecting men in the United States, and African American men have the highest incidence among men in the United States. Little is known about the PrCA-related educational materials being provided to patients in health-care settings. Content, readability, and cultural sensitivity of materials available in providers' practices in South Carolina were examined. A total of 44 educational materials about PrCA and associated sexual dysfunction was collec
BACKGROUND: To improve school store food environments, the South Korean government implemented 2 policies restricting unhealthy food sales in school stores. A food-based policy enacted in 2007 restricts specific food sales (soft drinks); and a nutrient-based policy enacted in 2009 restricts energy-dense and nutrient-poor (EDNP) food sales. The purpose of the study was to assess how the 2 policies have changed the school store food environment. METHODS: Foods sold in school stores in Seoul, South
The present study investigated the association between protein intake and lean mass according to obesity status over a 12-year period. Data on 4412 participants aged 40-69 years were obtained from the Korean Genome and Epidemiology Study. The usual dietary protein intake of these participants was assessed at baseline using a semi-quantitative FFQ. Body composition was measured using bioelectrical impedance analysis at baseline and after a 12-year follow-up. Linear mixed-effects models were used
전자정부는 일반적으로 부패를 통제하는 정책수단의 하나로 인식되면서 양자의 연관성에 대한 연구들이 축적되어 왔지만, 과연 어떤 과정을 거쳐 전자정부가 부패를 억제하는가에 대한 연구는 아직 드물다. 이에 본 연구는 전자정부가 부패에 미치는 영향이 정책투명성에 따라 어떻게 달라지는가를 국가차원의 자료를 중심으로 실증분석해 보고자 한다. 본 연구는 119개국의 2008년과 2010년 자료를 이용하여 전자정부가 부패에 미치는 영향이 정책결정의 투명성에 따라 달라짐을 검증하고자 한다. 본 연구의 분석결과에 따르면 정책결정의 투명성은 전자정부의 반부패효과에 있어 통계적으로 유의미한 조절변수로 나타났고, 정책결정의 투명성이 높을수록 전자정부의 반부패효과도 높게 나왔다. 본 연구의 시사점으로 전자정부의 반부패효과는 제도설비와 관리방식의 개혁에 따라 달라짐을 강조하였다.
