Introduction: Colorectal cancer is one of the most widespread and deadliest cancers. Vietnamese Americans exhibit persistently lower screening rates compared to the general United States population, which is due to cultural, economic, and environmental barriers. The impact of environmental factors in particular is not well known. This study aims to elucidate environmental factors affecting CRC screening rates among Vietnamese Americans.

Methods: A total of 517 Vietnamese Americans 50 years and older residing in Philadelphia County were included in the study. Surveys were collected to determine CRC screening behavior (colonoscopy and Fecal Immunochemical Test) and sociodemographic characteristics. Individual neighborhood characteristics, which included the Walk Score was obtained based on the participant’s address. Neighborhood characteristics were calculated using census-tract level data for the social deprivation index, ethnic composition, and presence of hospitals or federally qualified health centers (FQHC).

Results: The generalized linear mixed model revealed that residing in an ethnically dense neighborhood was negatively associated with CRC screening (β=-0.67, SE=0.29, p=0.01), while social deprivation (β=0.30, SE=0.27, p=0.27) and presence of FQHCs or hospitals (β=0.16, SE=0.30, p=0.58) were not significant. Individual neighborhood characteristics including the Walk Score (β=0.21, SE=0.26, p=0.43) was not associated with CRC screening behavior.

Discussion: Neighborhood characteristics, specifically ethnic density is associated with lower uptake of screening in this population. Future interventions should aim to target specific Asian neighborhoods that experience disparities in screening.
