About the Lab

Professor Juhwan Oh's research lab focuses on population health and public health policy, with a strong emphasis on understanding and addressing social determinants of health across the lifespan. The lab investigates multilevel risk and protective factors related to adolescent mental health, addictive behaviors, and the societal impacts of public health crises such as the COVID-19 pandemic. Research directions include health disparities, social support systems, and the effectiveness of national public health interventions, particularly in the context of low-income and vulnerable populations. The lab integrates epidemiological data with social science perspectives to inform evidence-based policies for health equity and resilience.

Juhwan Oh, Jong‐Koo Lee, Dan Schwarz, Hannah Ratcliffe, Jeffrey F. Markuns, Lisa R. Hirschhorn
SJR Q2FWCI 7.1Health Systems & ReformOA

In the first two months of the COVID-19 pandemic, the Republic of Korea (South Korea) had the second highest number of cases globally yet was able to dramatically lower the incidence of new cases and sustain a low mortality rate, making it a promising example of strong national response. We describe the main strategies undertaken and selected facilitators and challenges in order to identify transferable lessons for other countries working to control the spread and impact of COVID-19.

Mobility restrictions were associated with reductions in COVID-19 incidence early in the pandemic: evidence from a real-time evaluation in 34 countries

SJR Q1FWCI 7.3Scientific ReportsOA

Most countries have implemented restrictions on mobility to prevent the spread of Coronavirus disease-19 (COVID-19), entailing considerable societal costs but, at least initially, based on limited evidence of effectiveness. We asked whether mobility restrictions were associated with changes in the occurrence of COVID-19 in 34 OECD countries plus Singapore and Taiwan. Our data sources were the Google Global Mobility Data Source, which reports different types of mobility, and COVID-19 cases retrie

Socioeconomic Inequalities in Adolescent Depression in South Korea: A Multilevel Analysis
Hye Yin Park, Jongho Heo, S. V. Subramanian, Ichiro Kawachi, Juhwan Oh
SJR Q1FWCI 4.6PLoS ONEOA

The adolescent depression experience is not only an individual phenomenon but is highly associated with other factors such as parents, peers, academic achievement, and even gender mix in the school. Thus, prevention measures on youth depression need to focus on emphasizing less pressure from parents on academic performance, and establishing healthy inter-gender relationships within co-education schools.

Short-term and long-term associations between household wealth and physical growth: a cross-comparative analysis of children from four low- and middle-income countries

SJR Q1FWCI 3.4Global Health ActionOA

Household wealth in early life matters for physical growth with conditions of poverty and deprivation influencing growth faltering even beyond the 1,000 days window. The influences of early childhood poverty, so prevalent among children in low- and middle-income countries, must be addressed by policies and programs targeting early life but also focusing on older children experiencing growth faltering.

Precarious workers were more likely to be smokers and heavy smokers than standard workers. Unemployment is also a significant risk factor for decreased quitting and smoking relapse. However, insecure employment was an even more consistent determinant of current smoking behavior than unemployment.

SJR Q2FWCI 10.3Health Systems & ReformOA

<b>Abstract</b>-Although South Korea successfully established national health insurance (NHI) in 1977, and has maintained universal coverage since 1989, it has long been criticized for insufficient benefit coverage. Korea has been under public pressure to increase its NHI benefit coverage, while also facing controversies over the appropriateness of items that were newly added to the benefit package. Pressured by the controversies and difficulties regarding national policy decisions on the benefi

Use of modern contraceptives among married women in Vietnam: a multilevel analysis using the Multiple Indicator Cluster Survey (2011) and the Vietnam Population and Housing Census (2009)
Lan Vu, Juhwan Oh, Quyen Thi-Tu Bui, Lê Thị Kim Ánh
SJR Q1FWCI 4.6Global Health ActionOA

The proportion of women in Vietnam using modern contraceptive methods has remained relatively high in recent years with significant variation across Vietnam's 63 provinces. Women of lower SES are more likely to use modern contraceptive methods, especially in the poorer provinces. Achieving access to universal reproductive health is one of the Millennium Development Goals. Vietnam must continue to make progress in this area.

Changes and socioeconomic factors associated with attitudes towards domestic violence among Vietnamese women aged 15–49: findings from the Multiple Indicator Cluster Surveys, 2006–2011
Oanh Thi Hoang Trinh, Juhwan Oh, Sugy Choi, Kien Gia To, Do Van Dung
SJR Q1FWCI 4.0Global Health ActionOA

Higher educational attainment in women is an important predictor of women's attitudes toward domestic violence. To date, Doi Moi and the Vietnamese government's commitment to the Millennium Development Goals may have positively contributed to lowering the acceptance of domestic violence. Tailored interventions that focus on education will be important in further changing attitudes toward domestic violence.

Whilst caution is required in interpreting results given the cross-sectional nature of the study, our findings suggest that in addition to raising the price of cigarettes, youth anti-smoking interventions in South Korea may benefit from focusing on coeducation schools and vocational high schools.

Given the evidence from this study, actions to improve access to health care services among people with NCDs are clearly needed. The capacity of primary health care system for the prevention and control of NCDs should be ranked a top priority.
