Neighborhood Factors Associated with COVID-19 Cases in California.

BACKGROUND: There is a need to assess neighborhood-level factors driving COVID-19 disparities across racial and ethnic groups. OBJECTIVE: To use census tract-level data to investigate neighborhood-level factors contributing to racial and ethnic group-specific COVID-19 case rates in California. DESIGN: Quasi-Poisson generalized linear models were used to identify neighborhood-level factors associated with COVID-19 cases. In separate sequential models for Hispanic, Black, and Asian, we characterized the associations between neighborhood factors on neighborhood COVID-19 cases. Subanalyses were conducted on neighborhoods with majority Hispanic, Black, and Asian residents to identify factors that might be unique to these neighborhoods. Geographically weighted regression using a quasi-Poisson model was conducted to identify regional differences. MAIN MEASURES: All COVID-19 cases and tests reported through January 31, 2021, to the California Department of Public Health. Neighborhood-level data from census tracts were obtained from American Community Survey 5-year estimates (2015-2019), United States Census (2010), and United States Department of Housing and Urban Development. KEY RESULTS: The neighborhood factors associated with COVID-19 case rate were racial and ethnic composition, age, limited English proficiency (LEP), income, household size, and population density. LEP had the largest influence on the positive association between proportion of Hispanic residents and COVID-19 cases (- 2.1% change). This was also true for proportion of Asian residents (- 1.8% change), but not for the proportion of Black residents (- 0.1% change). The influence of LEP was strongest in areas of the Bay Area, Los Angeles, and San Diego. CONCLUSION: Neighborhood-level contextual drivers of COVID-19 burden differ across racial and ethnic groups.

Equitable COVID-19 Vaccination for Hispanics in the United States: A Success Story from California Border Communities.

The ongoing 2019 novel coronavirus disease (COVID-19) pandemic continues to impact the health of individuals worldwide, including causing pauses in lifesaving cancer screening and prevention measures. From time to time, elective medical procedures, such as those used for cancer screening and early detection, were deferred due to concerns regarding the spread of the infection. The short- and long-term consequences of these temporary measures are concerning, particularly for medically underserved populations, who already experience inequities and disparities related to timely cancer care. Clearly, the way out of this pandemic is by increasing COVID-19 vaccination rates and doing so in an equitable manner so that communities most affected receive preferential access and administration. In this article, we provide a perspective on vaccine equity by featuring the experience of the California Hispanic community, who has been disproportionately impacted by the pandemic. We first compared vaccination rates in two United States-Mexico border counties in California (San Diego County and Imperial County) to counties elsewhere in California with a similar Hispanic population size. We show that the border counties have substantially lower unvaccinated proportions of Hispanics compared to other counties. We next looked at county vaccination rates according to the California Healthy Places Index, a health equity metric and found that San Diego and Imperial counties achieved more equitable access and distribution than the rest of the state. Finally, we detail strategies implemented to achieve high and equitable vaccination in this border region, including Imperial County, an agricultural region that was California's epicenter of the COVID-19 crisis at the height of the pandemic. These United States-Mexico border county data show that equitable vaccine access and delivery is possible. Multiple strategies can be used to guide the delivery and access to other public health and cancer preventive services.

The COVID-19 Pandemic: Identifying Adaptive Solutions for Colorectal Cancer Screening in Underserved Communities.

The 2019 novel coronavirus disease (COVID-19) pandemic has dramatically impacted numerous health and economic fronts. Because of the stay-at-home mandate and practice of physical distancing, nearly all preventive care measures have been halted, including colorectal cancer (CRC) screening. The health consequences of this temporary suspension are of great concern, particularly for underserved populations, who experience substantial CRC-related disparities. In this commentary, we describe challenges and opportunities to deliver COVID-19-adapted CRC screening to medically underserved populations receiving care in community health centers (CHC). This perspective is based on key informant interviews with CHC medical directors, teleconference discussions, and strategic planning assessments. To address the unprecedented challenges created by the COVID-19 pandemic, we identify 2 broad calls to action: invest in CHCs now and support equitable and adaptable telehealth solutions now and in the future. We also recommend 4 CRC-specific calls to action: establish COVID-19-adapted best practices to implement mailed fecal immunochemical test programs, implement grassroots advocacy to identify community gastroenterologists who commit to performing colonoscopies for CHC patients, assess cancer prevention priorities among individuals in underserved communities, and assess regional CRC screening and follow-up barriers and solutions. The COVID-19 pandemic may further exacerbate existing CRC screening disparities in underserved individuals. This will likely lead to delayed diagnosis, a shift to later-stage disease, and increased CRC deaths. To prevent this from happening, we call for timely action and a commitment to address the current extraordinary CRC screening challenges for vulnerable populations.
