Colorectal Cancer-Related Knowledge, Acculturation, and Healthy Lifestyle Behaviors Among Low-Income Vietnamese Americans in the Greater Philadelphia Metropolitan Area.

Colorectal cancer (CRC) is the second and fourth most common cancer in Vietnamese American women and men, respectively. Recent research has highlighted the importance of modifiable lifestyle behaviors such as smoking, alcohol use, dietary behaviors, and physical activities in CRC prevention for the general population. However, it is not well understood how well Vietnamese Americans knew about CRC prevention and risk factors, and whether there were any disparities in knowledge within this vulnerable population. This study examined whether comprehensive measures of acculturation and knowledge of CRC risk are associated with different health behaviors, specifically physical activity, protective dietary behaviors, and risky dietary behaviors in Vietnamese Americans. We recruited 374 Vietnamese Americans aged 50 or above from community-based organizations in the Vietnamese American communities in the greater Philadelphia metropolitan area. Through a cross-sectional survey, we collected data on their knowledge of CRC prevention and risk factors, acculturation-related factors, and sociodemographic characteristics. We found limited knowledge of CRC prevention and risk factors, and suboptimal physical activity and healthy dietary behaviors in the Vietnamese Americans. We also found that higher levels of knowledge about CRC and risk factors were associated with less unhealthy diets but not with more protective diets or physical activity. Acculturation was not significantly associated with overall dietary behaviors in our study. Our findings addressed gaps in current literature concerning the impact of knowledge about CRC risk factors and acculturation on different dimensions of dietary behaviors as well as physical activity. Research and practical implications were discussed.

Effective Recruitment Strategies Utilized to Examine Dietary Practices of Blacks in New York City in the Midst of the COVID-19 Pandemic.

BACKGROUND: Black Americans have long been considered a hard-to-reach population for research studies, whether quantitative surveys or for clinical research. Studies have explored multiple rationales for why Blacks are hard to reach, and the explanations have included historical mistrust, the need to assess the benefits from participating in research, and the expense of spending time participating in research, among others. What has not been explored is the continuous merging of all individuals who identify as Black, particularly when exploring reasonings for a lower interest in participating in research. This paper addresses this issue by investigating the participation rate of individuals identifying as Black in New York City in a study exploring dietary practices as a predictor of colorectal cancer screening behavior. Participants were asked to self-report screening behavior, intent to screen, and dietary and other lifestyle practices. In this analysis, we discuss the unique experience encountered in recruiting Black American participants to participate in this study, particularly amid a worldwide pandemic of COVID-19. METHODS: The methodology for this study included a systematic review of the literature, a two-part recruitment process, and data analysis. The first part of the recruitment process involved registering individuals who were interested in participating in the study and consented to be contacted and reminded to come to the location where they were recruited on a scheduled date to complete the actual survey. With this part of the recruitment process, we engaged with n = 488 Black men and women between November 2019 and February 2020. The second part of the recruitment process utilized availability sampling outside of NYC subway stations and other high traffic areas as well as large community events. We engaged with n = 319 individuals. Total engagement with n = 807 individuals yielded a sample size for the survey of 504 completed surveys. RESULTS: Of the total engaged (n = 807), 14% declined to participate due to a lack of time, 11% chose not to participate in the study because the incentive was not enough to compensate for their time 0.02% declined due to not trusting institutions conducting research, and 0.03% did not feel comfortable understanding the questions due to a language barrier. We had a sample size of (n = 504) of the total 807 individuals engaged. CONCLUSIONS: Recruiting Black Americans into our colorectal cancer study did not prove to be challenging with the two-tiered model of recruitment that involved consistent engagement and having the primary researcher lead this recruitment process. Extracting within race differences is critical in demystifying the conclusion of numerous studies that African Americans specifically are hesitant to participate due to historical mistrust related to tragedies such as the Tuskegee Experiment and numerous other occurrences of African Americans being treated as guinea pigs for the advancement of research. This data contributes knowledge to this field regarding understanding recruitment challenges in the Black population, but further work needs to be conducted. Mistrust in this study primarily came from the individuals engaged in Caribbean neighborhoods, where many expressed more comfort with home remedies and bush doctors when asked about colorectal cancer screening and declined to participate. Innovative communication, qualitative research, and recruitment strategies tailored to the Caribbean population are needed in future studies to address this recruitment challenge that we experienced.
