About the Lab
Professor Sujung Choi's research lab focuses on population health and preventive medicine, with a strong emphasis on metabolic syndrome, sleep disorders, and their interrelationships in adult and clinical populations. The lab investigates lifestyle, occupational, and behavioral factors—including shift work, alcohol consumption, and sleep patterns—that influence metabolic and mental health outcomes. A significant portion of the research also explores non-pharmacological interventions, such as breast milk olfactory stimulation, to improve health outcomes in vulnerable populations like premature infants. The lab employs large-scale national survey data and clinical cohort studies to inform public health policy and preventive strategies.

15본 연구에서는 국민건강영양조사자료를 이용하여 IDF 기준에 의한 우리나라 20세 이상 성인의 대사증후군 유병률과 관련 요인을 규명하고자 시행되었다. 2010년 제5차 국민건강영양조사에 참여한 5670명의 자료를 이용하였다. 본 연구에서 자료 분석은 SAS 9.2 통계분석프로그램을 사용하였으며, 분석 시 복합표본설계를 이용하여 표본추출한 자료에 적용하는 SAS 명령어를 사용하였으며, 표본 추출률을 반영한 설계가중치, 무응답률, 사후 층화, 극단 가중치 처리단계를 거쳐 최종 산출된 개인가중치를 모두 적용하였다. 인구학적 특성, 생활습관, 가족력 등에 따른 모집단의 대사증후군의 유병률 추정치와 집단간 유병률의 차이를 비교하였고, 대사증후군 관련 요인을 파악하기 위하여 교차비 추정치와 이의 95% 신뢰구간을 구하였다. 우리나라 성인의 대사증후군 유병률은 18.8%였다. 인구학적 특성별로 대사증후군 유병률을 살펴보면, 남성 16.8%, 여성 20.7%였다. 20대 연령은 4.5%, 70대는
Sleep disturbances are more frequent in shift workers than DW. Depressive mood and anxiety symptoms were frequently reported in 3S, then EOD. Different shift schedules cab be a determinant of depressive mood and anxiety symptom.
Purpose: Shift work disrupts the synchronization between the human biological clock and the environment. Sleep disturbances are common for shift work nurses, and may threaten patient safety. This study was done to investigate the sleep characteristics and medication errors (ME) of intensive care unit (ICU) nurses who work shifts, and ascertain if there is an association between these factors. Methods: Data were collected using a self-report questionnaire from 126 ICU nurses on three shifts. Coll
Objectives: To investigate sleep-wake patterns and chronotype in rapidly rotating shift nurses (SRN). Methods: We translated and back-translated the Korean Munich ChronoType for Shift-Workers (K-MC-TQ shift ) with original authors' permission. In this study, 353 full-time, SRN (age 28.73.95 years 341 females, mean shift-working duration=5 years 9 months) at one university hospital completed the K-MCTQ shift and the Morningness-Eveningness Questionnaire (MEQ). Time in bed, sleep duration, and mid
Purpose: This study aimed to evaluate the effect of breast milk olfactory stimulation on pain response in premature infants during heel stick tests. Methods: A quasi-experimental randomized controlled trial was conducted in the neonatal intensive care unit of a tertiary-level hospital in Seoul, Korea. A breast milk group was provided olfactory stimulation with breast milk 30 seconds before the start of heel stick sampling, and a control group underwent heel stick sampling without olfactory stimu
To investigate the associations between amount of habitual alcohol consumption (HAC) and prevalence of metabolic syndrome (MetS), sleep, and sleep-disordered breathing (SDB). We enrolled 683 untreated SDB male patients (age: 54.4 ± 7.80 y, apnea-hypopnea index (AHI): 29.0 ± 21.53/h). HAC was assessed as the average number of drinks consumed per week during the past 12 months. Anthropometric and biochemical markers were used to diagnose MetS. Clinical data and MetS components were compared accord
Objectives: Shift workers are at risk for various sleep and health-related problems. To investigate light exposure and sleep-wake pattern according to shift schedules in shift workers. Methods: We enrolled 12 fulltime, rapidly rotating three-shift female nurses (age 26.4±4.01 years). They completed sleep logs and actigraphy monitoring of sleep-wake parameters, light exposure, and activity levels for over 14 days (mean numbers of night shifts 2.5). Results: Before beginning shift work, participan
The aim of this study was to compare shift satisfaction, sleep, fatigue, quality of life (QOL), and patient safety incidents between a newly implemented two-shift system and a traditional three-shift system. Methods : A total of 127 intensive care unit nurses (48 two-shift nurses and 79 three-shift nurses) working in a tertiary hospital in Seoul were recruited from January 1, 2017, to March 31, 2017. They completed a self-reported questionnaire about their work hours, shift satisfaction, sleep p
Integrating these roles within the framework of APN can offer a sustainable and legally sound solution to the ongoing healthcare crisis, ensuring patient safety and safeguarding healthcare workers' legal rights.
Purpose : This study aimed to propose a common scope of practice (SOP) for 13 specialties of Advanced Practice Nurses (APNs) in Korea. Methods : The first draft of a common SOP was extracted from domestic and international laws with a literature review by 17 experts from the Korean Association of Advanced Practice Nurses (KAAPN). Then, the common SOP was finalized after comparing the activities of APNs in clinical settings. Results : A total of 70 duties were identified and six categories were s
