RESUMEN
BACKGROUND: Asian Americans with metastatic cancer are an understudied population. The Describing Asian American Well-Being and Needs in Cancer (DAWN) Study was designed to understand the supportive care needs of Chinese-, Vietnamese-, and Korean-descent (CVK) patients with metastatic cancer. OBJECTIVE: This study aims to present the DAWN Study protocol involving a primarily qualitative, convergent, mixed methods study from multiple perspectives (patients or survivors, caregivers, and health care professionals). METHODS: CVK Americans diagnosed with solid-tumor metastatic cancer and their caregivers were recruited nationwide through various means (registries, community outreach newsletters, newspapers, radio advertisements, etc). Potentially eligible individuals were screened and consented on the web or through a phone interview. The study survey and interview for patients or survivors and caregivers were provided in English, traditional/simplified Chinese and Cantonese/Mandarin, Vietnamese, and Korean, and examined factors related to facing metastatic cancer, including quality of life, cultural values, coping, and cancer-related symptoms. Community-based organizations assisted in recruiting participants, developing and translating study materials, and connecting the team to individuals for conducting interviews in Asian languages. Health care professionals who have experience working with CVK patients or survivors with metastatic solid cancer were recruited through referrals from the DAWN Study community advisory board and were interviewed to understand unmet supportive care needs. RESULTS: Recruitment began in November 2020; data collection was completed in October 2022. A total of 66 patients or survivors, 13 caregivers, and 15 health care professionals completed all portions of the study. We completed data management in December 2023 and will submit results for patients or survivors and caregivers to publication outlets in 2024. CONCLUSIONS: Future findings related to this protocol will describe and understand the supportive care needs of CVK patients or survivors with metastatic cancer and will help develop culturally appropriate psychosocial interventions that target known predictors of unmet supportive care needs in Chinese, Vietnamese, and Korean Americans with metastatic cancer.

BACKGROUND: Prevalence of hepatitis C virus (HCV) infection among Vietnamese Americans is reportedly high. Understanding the profile of those at greater risk of HCV in this ethnic population is a vital step to addressing this high prevalence. We hypothesize that certain sociodemographic characteristics increase the likelihood of having HCV in Vietnamese Americans. METHODS: Cross-sectional data from 2,497 Vietnamese Americans in Southern California who participated in a series of community hepatitis screening events organized by the Vietnamese American Cancer Foundation (VACF) were analyzed. Serological tests via immunoassays were used to determine whether the participant had hepatitis C antibodies (anti-HCV) to indicate a HCV infection. Sociodemographic characteristics as well as participants' reasons for screening were collected from questionnaires, and logistic regression models with odds ratios (ORs) and 95% confidence intervals (CIs) were used to quantify their associations with HCV infection. RESULTS: Approximately 5.8% of the study population was infected with HCV. Older adults and male participants had higher odds of being infected with HCV (e.g. OR = 2.90, 95% CI 1.25-6.76 for ages 70+ versus ages <40; OR = 2.57, 95% CI 1.79-3.69 for male versus female participants) as were those with a family history of HCV infection (OR = 2.74, 95% CI 1.57-4.78). In addition, perceived self-risk as a motivation for screening was significantly associated with HCV infection (OR = 1.88, 95% CI 1.26-2.78). CONCLUSIONS: This study identifies specific subgroups in the Vietnamese American community who would largely benefit from targeted interventions given their higher likelihood of having HCV. These interventions should emphasize improving HCV knowledge and promoting HCV self-risk assessment since awareness of one's own risk may motivate those likely to be infected to get screened.

OBJECTIVES: The aims of our study were to describe current hepatitis B prevalence among Vietnamese Americans and to examine predictors of hepatitis B risk in this specific ethnic community. DESIGN: Cross-sectional analysis of data from a community-based screening program. SETTING: This analysis was based on hepatitis screening community events in Southern California. PARTICIPANTS: 2508 Vietnamese Americans in Southern California. OUTCOME MEASURES: Serological tests for hepatitis B surface antigen, hepatitis B surface antibody, and total hepatitis B core antibody were used to classify participants as one of four hepatitis B infection statuses: currently infected, previously infected, susceptible, or immune due to a previous hepatitis B vaccination. RESULTS: Across 2508 participants, 9.0% were currently infected with hepatitis B and 17.7% were at risk for hepatitis B. Females and those reporting a previous hepatitis B vaccination were at significant decreased risk of hepatitis B (OR=0.48, 95% CI 0.33 to 0.69 and OR=0.53, 95% CI 0.31 to 0.93, respectively) whereas those born outside of the USA and with a family history of the disease showed substantial increased risk (OR=13.36, 95% CI 1.62 to 110.05 and OR=4.68, 95% CI 2.66 to 8.22, respectively). Among those who reported a previous hepatitis B vaccination, less than half (42.9%) possessed the protective antibodies that result from a hepatitis B vaccination. CONCLUSIONS: Vietnamese Americans remain disproportionately burdened by hepatitis B. Public health efforts that focus on improving hepatitis B awareness and vaccination knowledge and that are tailored to specific high-risk subgroups, such as immigrants and those with infected family members, could help in addressing the disease's burden in this high-prevalence population.
