Cultural Factors relevant to Korean Americans in Health Research: A Systematic Review

Health Literacy among Korean American Immigrant Women in the USA: Role of Social Support

Health literacy is associated with health behaviors and outcomes. Using Andersen's Behavioral Model of Health Services Use, this study examined the role of limited English proficiency (LEP) and social support for the health literacy of Korean American immigrant women, one of the most affected groups by LEP. Researchers surveyed 232 Korean American immigrant women in a metro area in a Southeastern state, U.S. Health literacy was measured by the CDC Behavioral Risk Factor Surveillance System Questionnaire and the California Health Interview Survey. Participants with better English proficiency and larger social support had higher health literacy. LEP and social support interaction was significantly associated with health literacy, illustrating social support as a buffer that mitigates the negative impact of LEP on health literacy. Community programs that enhance social support through community health advocates or peer educators may increase health literacy and reduce health disparities among Korean American immigrant women with LEP.

Turning the Health Equity Lens to Diversity in Asian American Health Profiles

The monolithic misrepresentation of Asian American (AsAm) populations has maintained assumptions that AsAm people are not burdened by health disparities and social and economic inequities. However, the story is more nuanced. We critically review AsAm health research to present knowledge of AsAm health profiles from the past two decades and present findings and opportunities across three topical domains: (a) general descriptive knowledge, (b) factors affecting health care uptake, and (c) effective interventions. Much of the literature emphasized underutilization of health care services; low knowledge and awareness among AsAms about health-related risk factors, prevention, diagnosis, and treatment; inadequate efforts by health systems to improve language access, provider-patient communication, and trust; and the critical roles of community- and faith-based organizations and leaders in health promotion initiatives. Future opportunities for AsAm health research will require adoption of and significant investment in community-engaged research infrastructure to increase representation, funding, and research innovation for AsAm communities.

The Moderating Role of Collectivism on Physical Activity and Family Support: A Cross-Sectional Design

BACKGROUND

An important value among Korean Americans is collectivism or giving a group priority over the individual. This value, family support, and demographic characteristics have been reported to influence health behaviors among this group. Yet, no study has examined how collectivism, family support, and demographic characteristics interact with each other and then influence physical activity among Korean American adults. The purpose of the study was to examine the association between family support and physical activity, and the moderating role of demographic characteristics and collectivism on this association among Korean American adults.

METHODS

A descriptive, cross-sectional study was conducted with a sample of 110 Korean American adults 18 years and older, residing in a Southwestern city in the United States. Self-administered questionnaires were used to measure demographics, collectivism, family support, and physical activity.

RESULTS

Data analysis using a zero-inflated negative binomial regression model revealed a positive relationship between family support and physical activity, while age and gender were moderators of the relationship between family support and physical activity. Collectivism was positively related to physical activity and moderated the relationship between family support and physical activity.

CONCLUSION

These findings indicate the significance of collectivism and family support that influence Korean American adults' physical activity.

Korean American Immigrant Women's Perceived Breast Cancer Risk and Prevention Beliefs: A Qualitative Study

INTRODUCTION

With the goal of informing culturally appropriate intervention strategies, the purpose of this qualitative study was to understand the Korean American immigrant women's (KAIW) perceptions of breast cancer risk and how their perceived risk, along with normative breast cancer prevention beliefs, shaped their attitudes toward mammography.

METHOD

Semi-structured individual interviews were conducted with 30 Korean women in Los Angeles County, Los Angeles, California. Braun and Clarke's thematic analysis was used to code and analyze interview data.

RESULTS

Two major themes were identified: (a) perceived risk of breast cancer and attitudes to prevention (e.g., worried and using all means of prevention) and (b) influences on attitudes to breast cancer prevention (e.g., family members and friends' cancer experiences).

DISCUSSION

Breast cancer prevention interventions for KAIW should target perceived breast cancer risk, social factors such as women's family roles and social networks, and health information evaluation skills.

Development and acceptability of a peer-paired, cross-cultural and cross-generational storytelling HPV intervention for Korean American college women

Although Korean American women have a higher risk of developing cervical cancer, currently there are limited culturally relevant intervention strategies for improving primary prevention of cervical cancer by promoting HPV vaccination in this population. This study reports the development of a cross-cultural, cross-generational storytelling HPV intervention using a peer-paired method, in which two storytellers interactively share their stories, as a particular innovation that might resonate with Korean American young women. The acceptability of the intervention was assessed by self-reported satisfaction and endorsement with the intervention in a pilot randomized control trial (RCT). We compared participants' responses to the intervention by their generation and cultural identity. One hundred and four Korean college women between the ages of 18-26 were recruited from the Northeastern US Participants randomized to the intervention group received a storytelling video (n = 54); the comparison group received written information (n = 50). The acceptability of the intervention was measured immediately post-intervention. The intervention group had significantly greater satisfaction than the comparison group (P < 0.05). Participants reported greater endorsement for videos that reflected their cultural and generational experiences. Future study is needed to examine the impact of such interventions on objective follow-up on HPV vaccination in a large-scale RCT.

Interventions for Cardiovascular Disease Risk Reduction in Korean Americans: A Systematic Review

This systematic review was to identify and synthesize literature that described the cultural appropriateness and effectiveness of interventions aimed at cardiovascular risk reduction in Korean Americans. We searched multiple electronic databases for studies published between January 2000 and August 2017 and identified 14 eligible research reports. All reviewed studies targeted first-generation Korean American adults. Most of the reviewed studies incorporated components of surface structure, and leveraged deep structure in those interventions. Significant changes in cardiovascular health outcomes were reported in most of the reviewed studies; however, the role of cultural factors in the outcomes was rarely evaluated, and few reported long-term effects. Future research needs to consider long-term effects. Deploying cultural factors and evaluating their contributions to the target outcomes will enhance the research on cardiovascular health disparities.
