Assessing Physicians' Recommendations for Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) Testing Among Minority Populations in Greater Philadelphia and New York City.

Deaths from liver cancer are on the rise and disproportionately affect minority racial/ethnic groups. In this study, we examined associations between physicians' recommendations for hepatitis B virus (HBV) and hepatitis C virus (HCV) screening and sociodemographic and lifestyle factors among minority populations in the areas of Greater Philadelphia and New York City. Using Poisson regression with robust variance estimation, we evaluated potential associations for 576 Hispanic American (HA), African American (AA), and Asian Pacific American (APA) adults, using blood tests as an outcome measure, with adjustment for sociodemographic factors We found that APAs (34.2%) were most likely to have a physician recommend HBV and HCV screening tests (34.2% and 27.1%, respectively), while HAs were least likely to receive an HBV recommendation (15.0%) and AAs were least likely to receive an HCV recommendation (15.3%). HAs were significantly likely to have never received a blood test for either HBV or HCV (RR = 1.25, 95% CI: 1.05, 1.49). APAs were significantly more likely to receive a screening recommendation for HBV (RR = 1.10, 95%CI: 1.01, 1.20) and to have a blood test (RR = 1.57, 95% CI: 1.06, 2.33). Our findings show that, among HAs, AAs, and APAs, physician recommendations are strongly associated with patients undergoing blood tests for HBV and HCV and that minority populations should increasingly be recommended to screen for HBV and HCV, especially given their elevated risk.

Feasibility of Single - Encounter Telemedicine Lung Cancer Screening: A Retrospective Cohort Study in an Underserved Population.

BACKGROUND: COVID-19 forced a delay of non-essential health services, including lung cancer screening. Our institution developed a single-encounter, telemedicine (SET) lung cancer screening whereby patients receive low-dose CT in-person, but counseling regarding results, coordination of follow-up care and smoking cessation is delivered using telemedicine. This study compares outcomes of SET lung cancer screening to our pre-COVID, single-visit, in-person (SIP) lung cancer screening. METHODS: A retrospective cohort study was performed we recorded independent variables of gender, race/ethnicity, age, educational attainment, smoking status and dependent variables including cancer diagnosis, stage and treatment between March 2019 to July 2021. Using retrospective analysis, we compared outcomes of SIP lung cancer screening before COVID-19 and SET lung cancer screening amid COVID-19. RESULTS: There was a significant difference in number of patients screened pre- and amid COVID-19.673 people were screened via SIP, while only 440 were screened via SET. SIP screening consisted of 52.5% Black/African American patients, which decreased to 37% with SET lung cancer screening. There was no significant difference in gender, age, or educational attainment. There was also no significant difference in Lung-RADS score between the 2 methods of screening or diagnostic procedures performed. Ultimately telemedicine based screening diagnosed fewer cancers, 1.6% diagnosed via telemedicine vs 3.3% screened by in person. CONCLUSION: We implemented SET lung cancer screening to continue lung cancer screening during a global pandemic. Our study established feasibility of telemedicine-based lung cancer screening among our predominantly African American/Black population, though fewer patients were screened. We found no difference in distribution between age, or educational attainment suggesting other factors discouraging lung cancer screening amid COVID-19.

A Comparative Trial of Improving Care for Underserved Asian Americans Infected with Hepatitis B Virus.

BACKGROUND: Hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma (HCC). Asian Americans have the highest incidence and mortality rates of HCC among all US racial/ethnic groups. Inadequate monitoring and treatment of chronic hepatitis B contribute to poor health outcomes and increased healthcare costs among Asian Americans. AIMS: The goal of this study is to assess the effect of a patient-led strategy on chronic hepatitis B monitoring and treatment adherence specifically among Asian Americans with culturally tailored Patient Navigator-led Intervention. METHODS: From 2015 to 2018, 532 eligible participants living with chronic hepatitis B in the greater Philadelphia and New York city metropolitan areas were randomly assigned to either the intervention group or the control group. Generalized linear mixed-effects models were used to estimate the odds ratio (OR) for rates of doctor visits for chronic hepatitis B and rates of alanine aminotransferase testing for evidence of liver damage. RESULTS: Intervention group had higher rates of doctor visits than the control group at both 6-month (77.22% vs. 45.75%) and 12-month assessments (90.73% vs. 60.61%). Significantly more intervention group participants received ALT testing than control group participants at 6-month (52.90% vs. 25.10%) and 12-month (75.40% vs. 46.75%) follow-up. CONCLUSIONS: Culturally and linguistically appropriate intervention has strong effects on adherence to follow-up care among Asian American hepatitis B patients experiencing challenges to medication adherence and follow up care. These findings further identify opportunities for practical implementation of evidence-based intervention that could lead to reductions in disparities in chronic liver disease and liver cancer among high-risk, underserved populations.

Knowledge Gaps, Challenges, and Opportunities in Health and Prevention Research for Asian Americans, Native Hawaiians, and Pacific Islanders: A Report From the 2021 National Institutes of Health Workshop.

Asian Americans (AsA), Native Hawaiians, and Pacific Islanders (NHPI) comprise 7.7% of the U.S. population, and AsA have had the fastest growth rate since 2010. Yet the National Institutes of Health (NIH) has invested only 0.17% of its budget on AsA and NHPI research between 1992 and 2018. More than 40 ethnic subgroups are included within AsA and NHPI (with no majority subpopulation), which are highly diverse culturally, demographically, linguistically, and socioeconomically. However, data for these groups are often aggregated, masking critical health disparities and their drivers. To address these issues, in March 2021, the National Heart, Lung, and Blood Institute, in partnership with 8 other NIH institutes, convened a multidisciplinary workshop to review current research, knowledge gaps, opportunities, barriers, and approaches for prevention research for AsA and NHPI populations. The workshop covered 5 domains: 1) sociocultural, environmental, psychological health, and lifestyle dimensions; 2) metabolic disorders; 3) cardiovascular and lung diseases; 4) cancer; and 5) cognitive function and healthy aging. Two recurring themes emerged: Very limited data on the epidemiology, risk factors, and outcomes for most conditions are available, and most existing data are not disaggregated by subgroup, masking variation in risk factors, disease occurrence, and trajectories. Leveraging the vast phenotypic differences among AsA and NHPI groups was identified as a key opportunity to yield novel clues into etiologic and prognostic factors to inform prevention efforts and intervention strategies. Promising approaches for future research include developing collaborations with community partners, investing in infrastructure support for cohort studies, enhancing existing data sources to enable data disaggregation, and incorporating novel technology for objective measurement. Research on AsA and NHPI subgroups is urgently needed to eliminate disparities and promote health equity in these populations.

Dietary behavior and urinary gallic acid concentration differences among underserved elder racial and ethnic minorities in New York City.

PURPOSE: Diet and nutrition are important for cancer prevention. To investigate associations between dietary behavior, demographics, and risk of cancer, we assessed dietary behavior and urinary concentration of gallic acid, a polyphenol with anticancer properties found in various fruits and vegetables, in racial and ethnic minorities. METHODS: Ninety-one (91) participants were recruited from senior centers in East Harlem, New York City, a racially diverse and underserved community. A National Institute of Health (NIH)-validated dietary survey questionnaire-was used to collect dietary fruits and vegetables consumption data. Demographic and cancer information were also collected. All 91 participants completed the survey and forty-five (45) participants provided urine samples for gallic acid analysis. RESULTS: Gender differences were significantly associated with dietary behavior and urinary gallic acid concentration (UGAC). Female participants had a higher total daily intake of fruits and a significantly higher UGAC compared to male participants (p < 0.05). Age was negatively associated with the serving quantity of French fries/fried potatoes and white potatoes (p < 0.05), while positively associated with the daily intake frequency and daily intake of fruits (p < 0.05). Furthermore, Asian race was associated with higher daily intake frequencies of fruits and vegetable soup (p < 0.05), compared to other races. In a multivariate analysis, a significant association was observed between the serving quantities of fruits and other vegetables and UGAC (p < 0.05) after controlling for demographic characteristics. CONCLUSION: The observed differences in dietary behavior and UGAC in this study provide limited information on the association between demographic differences and cancer prevalence in elder racial and ethnic minorities. Future research should investigate this association further for potential implications in cancer prevention.

Empowering Low-Income Asian American Women to Conduct Human Papillomavirus Self-Sampling Test: A Community-Engaged and Culturally Tailored Intervention.

BACKGROUND: Asian American women face disproportionate burden of cervical cancer (CC) than non-Hispanic white women in the U.S. The goal of this study was to assess the feasibility and impact of a culturally tailored intervention to promote Human papillomavirus (HPV) self-sampling test among hard-to-reach Asian American women. METHODS: We adopted the community-based participatory research (CBPR) approach to conduct this efficacy study. A total of 156 female participants (56 Chinese, 50 Korean, and 50 Vietnamese) were recruited from community-based organizations (CBOs) in the greater Philadelphia metropolitan area. The intervention components included HPV-related education, HPV self-sampling test kit and instructions, group discussions, and patient navigations, all available in Asian languages. We examined several outcomes, including the completion of HPV self-sampling, HPV-related knowledge, perceived social support, self-efficacy, and comfort with the self-sampling test at post-intervention assessment. RESULTS: The majority of Asian American women had low annual household income (62.3% earned less than $20,000) and low educational attainment (61.3% without a college degree). We found significant increase in participants' knowledge on HPV (baseline: 2.83, post: 4.89, P <.001), social support (baseline: 3.91, post: 4.09, P < .001), self-efficacy (baseline: 3.05, post: 3.59, P < .001), and comfortable with HPV self-sample test (baseline: 3.62, post: 4.06, P < .001). CONCLUSION: To the best of our knowledge, this is the first intervention study that promoted HPV self-sampling test among Asian American women. Our findings showed that CBPR culturally tailored intervention of self-sampling was highly effective in empowering low-income Asian American women to conduct HPV self-sampling tests.

Adaptation of diabetes prevention program for Chinese Americans - a qualitative study.

BACKGROUND: Studies have demonstrated that a culturally and linguistically tailored Diabetes Prevention Program (DPP) can be effective in reducing diabetes risk in Chinese Americans. The purpose of this study was to explore the cultural and linguistic acceptability of the Centers for Disease Control and Prevention's Prevent T2 curriculum in an online format in the Chinese American community in New York City (NYC). METHODS: Three focus groups among a total of 24 Chinese Americans with prediabetes and one community advisory board (CAB) meeting with 10 key stakeholders with expertise in diabetes care and lifestyle interventions were conducted. Each focus group lasted approximately 1 to 1.5 h. All groups were moderated by a bilingual moderator in Chinese. The sessions were audiotaped, transcribed and translated to English for analysis. Using Atlas.ti software and open coding techniques, two researchers analyzed transcripts for thematic analysis. RESULTS: Five key themes were identified: barriers to behavioral changes, feedback on curriculum content and suggestions, web-based intervention acceptability, web-based intervention feasibility, and web-based intervention implementation and modifications. Participants with prediabetes were found to have high acceptability of web-based DPP interventions. Suggestions for the curriculum included incorporating Chinese American cultural foods and replacing photos of non-Asians with photos of Asians. Barriers included lack of access to the internet, different learning styles and low technology self-efficacy for older adults. CONCLUSION: Although the acceptability of web-based DPP in the Chinese American community in NYC is high, our focus group findings indicated that the major concern is lack of internet access and technical support. Providing support, such as creating an orientation manual for easy online program access for future participants, is important.

A Multilevel Intervention to Increase HPV Vaccination among Asian American Adolescents.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the US. HPV vaccine is a viable source of prevention against high-risk strains that are likely to cause cancer. However, particularly among racial and ethnic minorities such as Chinese Americans, HPV vaccination rates are suboptimal. The goal of this study was to evaluate the effect of a culturally tailored intervention on HPV vaccine uptake in Chinese Americans. We designed and implemented a multilevel longitudinal pilot study to examine the efficacy of the HPV intervention among Chinese American parents/guardians. We recruited 180 participants from federally qualified health center and community-based clinics that serve predominantly low-income Chinese Americans in Philadelphia. Participants were randomized into an intervention group (n = 110) or a control group (n = 70). The intervention group received an HPV specific intervention, while the control group received a general health intervention. The primary outcome was medical record-confirmed receipt of first shot and completion of HPV vaccine within six months of receiving the interventions. Repeated measure ANOVA was utilized to examine the intervention effect on knowledge between intervention and control groups. Knowledge differed significantly, with participants in the intervention group demonstrating the greatest improvement following the intervention. A multivariable logistic regression was used to examine the association between HPV vaccine initiation and study group assignment. There was a significant effect of provider recommendation, parent's gender, and health insurance status on HPV vaccine uptake. This study demonstrated positive impact of a culturally tailored intervention on HPV vaccination uptake among Chinese Americans.

Effective Educational Approaches to Training Physicians About Lung Cancer Screening.

In 2013, the U.S. Preventative Services Task Force recommended low-dose computed tomography (LDCT) for lung cancer screening (LCS) after a national trial demonstrated a 20% reduction in lung cancer mortality with LDCT. Implementation of LCS employing LDCT depends heavily on physician education regarding multiple factors, including eligibility criteria, potential benefits and harms, and shared decision-making. To date, there are no studies of educational approaches for teaching physicians about LCS. This study aims to assess the feasibility and effectiveness of implementing an interactive, group-based learning (GBL) curriculum to teach physicians about LCS. A prospective study was conducted at two nearby institutions from 2017 to 2019 comparing GBL with a lecture format as measured by total knowledge about LCS, acceptability of the educational format, and ease of implementation. We surveyed participants regarding total knowledge and format acceptance. Results were compared to determine whether GBL is an effective and feasible educational strategy for LDCT and LCS education. Residents and faculty participating in GBL demonstrated greater total knowledge compared with residents and faculty participating in the lecture format. Participants in both cohorts preferred a mix of GBL and lecture formats. All participants believed that GBL facilitates implementation of LCS better than lecture-based learning. GBL is an effective and feasible approach for educating physicians about LCS, though it is more time- and resource-intensive than a lecture approach. However, healthcare providers believe GBL will facilitate implementation of LCS more than lectures.

Adherence to annual lung cancer screening with low-dose CT scan in a diverse population.

PURPOSE: Our aim was to develop a novel approach for lung cancer screening among a diverse population that integrates the Centers for Medicare and Medicaid Services (CMS) recommended components including shared decision making (SDM), low-dose CT (LDCT), reporting of results in a standardized format, smoking cessation, and arrangement of follow-up care. METHODS: Between October of 2015 and March of 2018, we enrolled patients, gathered data on demographics, delivery of SDM, reporting of LDCT results using Lung-RADS, discussion of results, and smoking cessation counseling. We measured adherence to follow-up care, cancer diagnosis, cancer treatment, and smoking cessation at 2 years after initial LDCT. RESULTS: We enrolled 505 patients who were 57% African American, 30% Caucasian, 13% Hispanic, < 1% Asian, and 61% were active smokers. All participants participated in SDM, 88.1% used a decision aid, and 96.1% proceeded with LDCT. Of 496 completing LDCT, all received a discussion about results and follow-up recommendations. Overall, 12.9% had Lung-RADS 3 or 4, and 3.2% were diagnosed with lung cancer resulting in a false-positive rate of 10.7%. All 48 patients with positive screens but no cancer diagnosis adhered to follow-up care at 1 year, but only 35.4% adhered to recommended follow-up care at 2 years. The annual follow-up for patients with negative lung cancer screening results (Lung-RADS 1 and 2) was only 23.7% after one year and 2.8% after 2 years. All active smokers received smoking cessation counseling, but only 11% quit smoking. CONCLUSION: The findings show that an integrated lung cancer screening program can be safely implemented in a diverse population, but adherence to annual screening is poor.

Inequities in Access to Care and Health Care Spending for Asian Americans With Cancer.

BACKGROUND: Asian Americans have lower cancer screening rates than non-Latino "Whites," suggesting inequities in cancer prevention among Asian Americans. Little is known about inequities in cancer treatment between Whites and Asian Americans with cancer. METHODS: Using the 2002-2017 Medical Expenditure Panel Survey, we examined inequities in access to care and health care spending between Whites and Asian Americans with and without cancer. Our outcomes included 3 measures of access to care and 3 measures of health care spending. We used multivariable regressions while adjusting for predisposing, enabling, and need factors and estimated the mean adjusted values of the outcomes for each group. We then examined the differences in these adjusted mean outcomes among Asian Americans relative to Whites. RESULTS: We observed evidence of inequities that Asian Americans without cancer experienced limited access to care due to a lack of a usual source of care. The likelihood of having a usual source of care was lower among Asian Americans without cancer than Whites without cancer. Inequities were not observed among Asian Americans with cancer. Compared with Whites with cancer, Asian Americans with cancer had similar or better levels of access to care. No or marginal differences in health care spending were detected between Whites and Asian Americans with cancer. These findings were consistent in both nonelderly and elderly groups. CONCLUSION: While Asian Americans without cancer have unmet medical needs due to limited access to care, access to care and spending are relatively equitable between Whites and Asian Americans with cancer.

Multilevel Pathways of Colorectal Cancer Screening Among Low-Income Vietnamese Americans: A Structural Equation Modeling Analysis.

BACKGROUND: Colorectal cancer (CRC) disproportionately affects Vietnamese Americans, especially those with low income and were born outside of the United States. CRC screening tests are crucial for prevention and early detection. Despite the availability of noninvasive, simple-to-conduct tests, CRC screening rates in Asian Americans, particularly Vietnamese Americans, remain suboptimal. The purpose of this study was to evaluate the interplay of multilevel factors - individual, interpersonal, and community - on CRC screening behaviors among low-income Vietnamese Americans with limited English proficiency. METHODS: This study is based on the Sociocultural Health Behavior Model, a research-based model that incorporates 6 factors associated with decision-making and health-seeking behaviors that result in health care utilization. Using a community-based participatory research approach, we recruited 801 Vietnamese Americans from community-based organizations. We administered a survey to collect information on sociodemographic characteristics, health-related factors, and CRC screening-related factors. We used structural equation modeling (SEM) to identify direct and indirect predictors of lifetime CRC screening. RESULTS: Bivariate analysis revealed that a greater number of respondents who never screened for CRC reported limited English proficiency, fewer years of US residency, and lower self-efficacy related to CRC screening. The SEM model identified self-efficacy (coefficient = 0.092, P < .01) as the only direct predictor of lifetime CRC screening. Educational attainment (coefficient = 0.13, P < .01) and health beliefs (coefficient = 0.040, P < .001) had a modest significant positive relationship with self-efficacy. Health beliefs (coefficient = 0.13, P < .001) and educational attainment (coefficient = 0.16, P < .01) had significant positive relationships with CRC knowledge. CONCLUSIONS: To increase CRC screening uptake in medically underserved Vietnamese American populations, public health interventions should aim to increase community members' confidence in their abilities to screen for CRC and to navigate associated processes, including screening preparation, discussions with doctors, and emotional complications.

Aiding shared decision making in lung cancer screening: two decision tools.

BACKGROUND: Shared decision making (SDM) preceding lung cancer screening is important for populations that are underrepresented in lung cancer screening trials. Current evidence-based guidelines; however, do not address personal risk and outcomes in underrepresented populations. This study compared two SDM decision aids (Option Grids and Shouldiscreen.com) for SDM efficacy, decision regret and knowledge. METHODS: We conducted a prospective trial of lung cancer screening patients (N = 237) randomized to SDM with Option Grids or Shouldiscreen.com. To evaluate the SDM process after lung cancer screening, patients answered two questionnaires: CollaboRATE and Decision Regret. Patients also completed a questionnaire to test their knowledge of lung cancer screening. RESULTS: Patients were predominantly African American (61.6%), though multiple races, varying education levels and equal genders were represented. Patients in both Option Grids and Shouldiscreen.com groups reported favorable SDM experiences (P = 0.60) and equivalent knowledge about lung cancer screening (P = 0.43). Patients using Shouldiscreen.com had less knowledge regarding the potential complications of subsequent testing (P = 0.02). Shouldiscreen.com patients had increased regret regarding their decision to pursue screening (P = 0.02). CONCLUSIONS: Option Grids and Shouldiscreen.com both facilitated a meaningful SDM process. However, Option Grids patients experienced decreased decision regret and enhanced knowledge of the potential complications of screening.

Effects of Neighborhood Ethnic Density and Psychosocial Factors on Colorectal Cancer Screening Behavior Among Asian American Adults, Greater Philadelphia and New Jersey, United States, 2014-2019.

INTRODUCTION: We examined how neighborhood ethnic composition influences colorectal cancer (CRC) screening behavior in Asian American adults and explored whether associations between psychosocial predictors, including knowledge, self-efficacy, and barriers affecting CRC screening behavior, varied by level of neighborhood ethnic composition. METHODS: Filipino, Korean, and Vietnamese Americans (N = 1,158) aged 50 years or older were included in the study. Psychosocial factors associated with CRC screening, CRC screening behavior, and sociodemographic characteristics were extracted from participants' data. Neighborhood ethnic composition was characterized as the census-tract-level percentage of Asian residents. Participants' addresses were geocoded to the census tract level to determine whether they resided in an ethnically dense neighborhood. Multilevel logistic regression models were run with and without interaction terms. RESULTS: In mixed-effects logistic regression model 1, residing in an ethnically dense neighborhood was associated with lower odds of CRC screening (odds ratio [OR] = 0.65; 95% CI, 0.45-0.93; P = .02) after controlling for age, sex, education, ethnic group, and neighborhood socioeconomic status. Greater perceived barriers to CRC screening (OR = 0.62; 95% CI, 0.50-0.77; P < .001) resulted in significantly lower odds of obtaining a CRC screening, while higher self-efficacy (OR = 1.17, 95% CI, 1.11-1.23, P < .001) was associated with higher odds. In model 2, among those residing in a high ethnic density neighborhood, greater barriers to screening were associated with lower odds of having obtained a CRC screening (OR = 0.53; 95% CI, 0.30-0.96; P = .04). CONCLUSION: We found that residing in an ethnically dense neighborhood indicated higher disparities in obtaining CRC screenings. Future studies should examine socioeconomic and cultural disparities, as well as disparities in the built environment, that are characteristic of ethnically dense neighborhoods and assess the impact of these disparities on CRC screening behaviors.

Examining Gender Differences in Lung Cancer Screening.

It is unknown if gender influences outcome of lung cancer screening with Low Dose CT (LDCT), especially with frequent and continued underrepresentation of women in clinical trials. We examined a balanced cohort of men and women with the hypothesis that there would be no difference in participation or results between men and women undergoing lung cancer screening. In an urban, academic medical center, we prospectively collected data on patients referred for lung cancer screening from October 2015 to August 2018. We studied gender, age, ethnicity, level of education and smoking history. We measured results of LDCT using Lung-RADS reporting system. 546 patients underwent LDCT between October 2015 and August 2018. 279 (51%) were female and 267 (49%) were males. Age, education status or smoking patterns did not significantly differ between females and males There was a significant difference between males and females in the distribution of LDCT results (p = 0.05). 81 females and 105 males were diagnosed with Lung-RADS 1; 99 females and 92 males with Lung-RADS 2; 15 females and 8 males with Lung-RADS 3; 19 females and 11 males with Lung-RADS 4. Overall, 10 females (3.5%) and 3 males (1.1%) were diagnosed with lung cancer (risk difference 2.4, 95% CI-0.0006-0.05, p = 0.09). Women are often underrepresented in clinical trials. Preliminary results from our lung cancer screening program demonstrate equal participation and equal benefit from the screening program. Long term data is needed to study survival benefit.

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.

Structural Interventions to Reduce and Eliminate Health Disparities.

Health disparities research in the United States over the past 2 decades has yielded considerable progress and contributed to a developing evidence base for interventions that tackle disparities in health status and access to care. However, health disparity interventions have focused primarily on individual and interpersonal factors, which are often limited in their ability to yield sustained improvements. Health disparities emerge and persist through complex mechanisms that include socioeconomic, environmental, and system-level factors. To accelerate the reduction of health disparities and yield enduring health outcomes requires broader approaches that intervene upon these structural determinants. Although an increasing number of innovative programs and policies have been deployed to address structural determinants, few explicitly focused on their impact on minority health and health disparities. Rigorously evaluated, evidence-based structural interventions are needed to address multilevel structural determinants that systemically lead to and perpetuate social and health inequities. This article highlights examples of structural interventions that have yielded health benefits, discusses challenges and opportunities for accelerating improvements in minority health, and proposes recommendations to foster the development of structural interventions likely to advance health disparities research.

Characterizing Occupational Health Risks and Chemical Exposures Among Asian Nail Salon Workers on the East Coast of the United States.

The products used in nail care services contain toxic chemicals. This study aimed to characterize occupational health risk factors and chemical exposures among Asian nail salon workers on the East Coast of the U.S. for informing the development of more effective, culturally appropriate interventions. We conducted a community-based participatory research (CBPR) study to characterize occupational health risks. A face-to-face, self-reported survey was performed, and personal exposure to volatile organic compounds (VOCs) was evaluated. Three VOCs, acetone, methyl methacrylate (MMA), and toluene, were measured using 3M 3500 organic vapor monitors. We collected data on 112 workers with 100 personal chemical exposure measurements from 25 nail salons. Self-reported health problems that emerged or worsened after participants started working in the nail salon industry included headaches (8%); lightheadedness (9.8%); and irritation to the nose, eyes, throat, and skin (21.2%). Approximately 70% of participants reported that they had been pregnant, 11.7% of whom had at least one miscarriage. The mean concentrations of acetone, MMA, and toluene were 18.51 parts per million (ppm), 39.45 ppm, and 0.09 ppm, respectively. Mean concentrations of acetone and MMA measured from salons in New York City were significantly lower than those measured in Philadelphia and southern New Jersey. CBPR proved to be as an efficient approach for recruiting hard-to-reach Asian immigrant nail salon workers. Adverse health symptoms and problems associated with providing nail salon services were identified in these workers. Further studies are needed to better understand the long-term health effects of chronic chemical exposures in nail salon environments.

Community-Based Cervical Cancer Education: Changes in Knowledge and Beliefs Among Vietnamese American Women.

Low cervical cancer screening rates among Vietnamese American women have been attributed, in part, to inadequate knowledge about cervical cancer and health beliefs that hinder screening. A community-based educational program was developed to improve knowledge and attitudes toward cervical cancer screening in this underserved population. It was hypothesized that the program would result in increases in knowledge, as well as enhanced health beliefs and self-efficacy toward obtaining cervical cancer screening. Using a group-randomized design, 1488 women from 30 Vietnamese community-based organizations were assigned to either the intervention (n = 816) or control (n = 672) conditions. The intervention group received cervical cancer education delivered by bilingual community health educators. Intervention content addressed individual beliefs and expectancies regarding cervical cancer screening (e.g., perceived risk of developing cervical cancer; perceived benefits and barriers to screening; social and cultural norms regarding screening). The control group received general health education, including information about cancer screening. Knowledge and health beliefs were assessed at baseline and post-intervention. Among women in the intervention group, overall knowledge about cervical cancer and screening guidelines increased from pre- to post-program (30% vs. 88%, p < 0.001), perceived benefits of screening increased (3.50 vs. 4.49, p < 0.001), and perceived barriers to screening decreased (3.13 vs. 2.25, p < 0.001). Changes in knowledge and health beliefs were not observed among women in the control group. A community-based educational program can help increase knowledge about cervical cancer and screening, promote positive changes in women's beliefs about the benefits of cervical cancer screening, and reduce perceived barriers to screening. Such programs may play an important role in addressing health disparities and informing underserved populations about recommended screening tests.

Hepatitis B Virus Screening and Vaccination in First-generation African Immigrants: A Pilot Study.

Foreign-born African immigrants bear a large burden of hepatitis B virus (HBV)-related liver disease in the U.S. However, HBV awareness and knowledge of HBV screening and vaccination among this population is limited. This study aimed to provide a better understanding of HBV burden in this vulnerable population and to identify risk factors for the implementation of more effective prevention and treatment programs. We conducted a cross-sectional survey among 71 first-generation African Americans in New York City. Participants' sociodemographic characteristics, HBV screening and vaccination history, knowledge of HBV transmission, and other related issues were asked. The study sample included 46 men and 23 women, with an average age of 32.75. Of the sample, 87.50% participants migrated from sub-Saharan Africa and 79.10% had lived in the U.S. for 10 or fewer years. Almost half of participants never underwent HBV screening (44.29%) or HBV vaccination (49.23%). About two-thirds (60.87%) of participants never received any HBV screening or vaccination recommendation from doctors. Multivariable analysis results showed that having a college degree and being currently married were significantly associated with HBV screening, while having health insurance was significantly associated with HBV vaccination. Survey data further indicated that first-generation African immigrants had very limited knowledge of HBV transmission, suggesting that this population would benefit from greater awareness of HBV risk factors and modes of transmission. The influence of education, marriage and spousal support, and access to health insurance on HBV screening and vaccination should be noted and further examined in future public health interventions and research.
