The COVID-19 pandemic has exposed the many broken fragments of US health care and social service systems, reinforcing extant health and socioeconomic inequities faced by structurally marginalized immigrant communities. Throughout the pandemic, even during the most critical period of rising cases in different epicenters, immigrants continued to work in high-risk-exposure environments while simultaneously having less access to health care and economic relief and facing discrimination. We describe systemic factors that have adversely affected low-income immigrants, including limiting their work opportunities to essential jobs, living in substandard housing conditions that do not allow for social distancing or space to safely isolate from others in the household, and policies that discourage access to public resources that are available to them or that make resources completely inaccessible. We demonstrate that the current public health infrastructure has not improved health care access or linkages to necessary services, treatments, or culturally competent health care providers, and we provide suggestions for how the Public Health 3.0 framework could advance this. We recommend the following strategies to improve the Public Health 3.0 public health infrastructure and mitigate widening disparities: (1) address the social determinants of health, (2) broaden engagement with stakeholders across multiple sectors, and (3) develop appropriate tools and technologies.

Dyspnoea self-management is often suboptimal for patients with COPD. Many patients with COPD experience chronic dyspnoea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioural intervention that targets reducing the distress and impact of dyspnoea on exertion in daily living. Using a qualitative design, we conducted interviews with 14 patients after they participated in a novel mind-body breathing therapy intervention adjunct, capnography-assisted respiratory therapy (CART), combined with outpatient pulmonary rehabilitation. Comprehensive CART consisted of patient-centred biofeedback, tailored breathing exercises, a home exercise programme and motivational interviewing counselling. We assessed participants' perceptions and reported experiences to gauge the acceptability of CART and refine CART based on feedback. Constant comparative analysis was used to identify commonalities and themes. We identified three main themes relating to the acceptability and reported benefits of CART: (1) self-regulating breathing; (2) impact on health; and (3) patient satisfaction. Our findings were used to refine and optimise CART (i.e. its intensity, timing and format) for COPD. By addressing dysfunctional breathing behaviours and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnoea and related anxiety in patients with COPD.

Chinese Americans experience cancer health disparities throughout the entire cancer continuum. Yet, they remain underrepresented in health research in part due to barriers in recruitment, engagement, and retention. This paper describes the strategies that we devised, by drawing upon our experiences with conducting two culturally sensitive cancer intervention studies, to help researchers improve their recruitment and retention rates of Chinese Americans in health research and address the gap in knowledge on intervention research with this population. The first study assessed the efficacy, adoption, and impact of an intervention, delivered by community health workers, to improve adherence to recommended stomach cancer prevention guidelines for at-risk Chinese Americans. The second study evaluated the feasibility and preliminary efficacy of a culturally adapted version of the Expressive Helping intervention for Chinese American cancer patients and survivors. Our main recruitment strategies revolved around building community relationships, developing culturally sensitive materials, and establishing good first impressions with participants. Our main engagement and retention strategies focused on attending to cultural sensitivity, fostering relationships, and using technology. Harnessing the community's inherent strengths and prioritizing cultural understanding is crucial for culturally sensitive health research with Chinese Americans.

BACKGROUND:Colorectal cancer is the second leading cause of cancer death among Hispanic Americans. Puerto Ricans are the second largest Hispanic subgroup in the USA and the largest in New York City, but little is known about predictors of colorectal cancer screening uptake in this population. AIMS/OBJECTIVE:We used the New York City Community Health Survey, a population-based telephone survey, to investigate predictors of up-to-date colonoscopy use over time among Puerto Ricans aged ≥ 50 years in NYC. METHODS:We assessed the association between sociodemographic and medical factors and up-to-date colonoscopy use (defined as colonoscopy within the last 10 years) using univariable and multivariable logistic regression over six time periods: 2003-2005, 2006-2008, 2009-2010, 2011-2012, 2013-2014, and 2015-2016. RESULTS:On multivariable analysis, age ≥ 65 years (OR 1.64-1.93 over three periods) and influenza vaccination (OR 1.86-2.17 over five periods) were the two factors most consistently associated with up-to-date colonoscopy use. Individuals without a primary care provider (OR 0.38-0.50 over three periods) and who did not exercise (OR 0.49-0.52 over two periods) were significantly less likely to have an up-to-date colonoscopy. CONCLUSIONS:Older age, influenza vaccination, having a primary care provider, and exercise are independent predictors of up-to-date colonoscopy use among Puerto Ricans in NYC. Interventions to improve screening colonoscopy uptake among Puerto Ricans should be targeted to those aged 50-64 years and who do not have a primary care provider.

No brief dietary screeners are available that capture dietary consumption patterns of Asian Americans. The purpose of this article is to describe the cultural adaptation of the validated Dietary Screener Questionnaire (DSQ) for use by clinicians, researchers, and community-based partners seeking to understand and intervene on dietary behaviors among English-speaking Asian Americans, for the six largest Asian subgroups (Chinese, Filipino, Asian Indian, Vietnamese, Korean, Japanese) in the United States. This was mainly accomplished by adding culturally specific examples of foods to the questionnaire items via searching online databases and soliciting input from members of our community partner network representing each of the six largest Asian subgroups. Over half of the 26 items on the DSQ were modified to include more culturally specific foods. Developing high-quality tools that reflect the diversity of the U.S. population are critical to implement nutrition interventions that do not inadvertently widen health disparities.

To assess colorectal cancer (CRC) screening among South Asians (SAs) and explore the challenges and facilitators to CRC screening among SA subgroups in New York City (NYC). Fifty-one semi-structured in-depth interviews and surveys were conducted among SA immigrants in NYC. Qualitative results suggested challenges to CRC screening were related to socio-cultural factors, such as a lack of knowledge on CRC and CRC screening, and structural factors, such as cost and language. A physician referral was the most cited facilitator to CRC screening. Participants reported culturally and linguistically adapted education and information on CRC and CRC screening would help to overcome noted challenges. Our findings support the development of targeted, linguistically and culturally adapted campaigns for this population that facilitate access to health systems and leverage natural community assets and social support systems.

Immigration has been historically and contemporarily racialized in the United States. Although each immigrant group has unique histories, current patterns, and specific experiences, racialized immigrant groups such as Latino, Asian, and Arab immigrants all experience health inequities that are not solely due to nativity or years of residence but also influenced by conditional citizenship and subjective sense of belonging or othering. Critical race theory and intersectionality provide a critical lens to consider how structural racism might uniquely impact the health of racialized immigrants, and to understand and intervene on the interlocking systems that shape these shared experiences and health consequences. We build on and synthesize the work of prior scholars to advance how society codifies structural disadvantages for racialized immigrants into governmental and institutional policies and how that affects health via three key pathways that emerged from our review of the literature: (1) formal racialization via immigration policy and citizenship status that curtails access to material and health resources and political and civic participation; (2) informal racialization via disproportionate immigration enforcement and criminalization including ongoing threats of detention and deportation; and (3) intersections with economic exploitation and disinvestment such as labor exploitation and neighborhood disinvestment. We hope this serves as a call to action to change the dominant narratives around immigrant health, provides conceptual and methodological recommendations to advance research, and illuminates the essential role of the public health sector to advocate for changes in other sectors including immigration policy, political rights, law enforcement, labor protections, and neighborhood investment, among others.

OBJECTIVES/OBJECTIVE:Patient-provider communication is essential for patient-centered care, yet Asian American immigrant populations face barriers. We aim to describe: 1) patient-reported communication-related characteristics for 16 disaggregated Asian American subgroups; and 2) the association of patient comprehension of provider communication with socio-demographics, language proficiency and concordance, and perceived cultural sensitivity in this population. METHODS:Descriptive statistics are presented for 1269 Asian American immigrants responding to cross-sectional, venue-sampled surveys conducted in New York City. Logistic regression models examine predictors of low comprehension of provider communication. RESULTS:Approximately 11% of respondents reported low comprehension of provider communication: lowest among South Asians and highest among Southeast Asians. Eighty-four percent were language-concordant with their provider, 90.1% agreed that their provider understood their background and values, and 16.5% felt their provider looked down on them. Low comprehension of provider communication was significantly associated with Southeast Asian subgroup, less education, limited English proficiency, public health insurance, patient-provider language discordance, and perceived low cultural understanding. CONCLUSION/CONCLUSIONS:Among our sample, language and cultural sensitivity are associated with comprehension of provider communication. PRACTICE IMPLICATIONS/CONCLUSIONS:Strategies improving language access and cultural sensitivity may be important for Asian immigrant patients. These could include interpretation services, bilingual community-based providers, and cultural sensitivity training.

Purpose: Dietary behaviors are key modifiable risk factors in averting cardiovascular disease (CVD), the leading cause of morbidity, mortality, and disability in the United States. Before investing in adoption and implementation, community-based organizations, public health practitioners, and policymakers-often working with limited resources-need to compare the population health impacts of different food policies and programs to determine priorities, build capacity, and maximize resources. Numerous reports, reviews, and policy briefs have synthesized across evidence-based policies and programs to make recommendations, but few have made a deep acknowledgment that dietary policies and programs are not implemented in a vacuum, and that "real-world" settings are complex, multifaceted and dynamic. Methods: A narrative review was conducted of currently recommended evidence-based approaches to improving dietary behaviors, to describe and characterize applied and practical factors for consideration when adopting and implementing these dietary policies and programs across diverse settings. Results: From the narrative review, six key considerations emerged to guide community-based organizations, public health practitioners, and policymakers on moving from the evidence base, toward implementation in local and community settings. Conclusions: Considerations of "real-world" contextual factors are necessary and important when adopting and selecting evidence-based policies and programs to improve dietary behaviors and ultimately improve CVD outcomes. Promising approaches include those that apply community-partnered research and systems science to examine the equitable implementation of evidence-based dietary policies and programs.
