Changes in alcohol consumption and binge drinking during the COVID-19 pandemic among American Indians residing in California and Oklahoma.

Background: This study explored the increased quantity and frequency of alcohol use in the American Indian (AI) population during the COVID-19 pandemic.Objectives: The aims of this study were to explore possible associations between covariables and both binge drinking and alcohol consumption during COVID-19.Methods: This cross-sectional survey study analyzed data from a sample of AI individuals (63% female) residing in California (n = 411) and Oklahoma (n = 657) between October 2020-January 2021. Analysis included summary statistics and multivariable logistic regression, including a variety of socio-economic, COVID-19 concern, and tobacco and marijuana use variables.Results: One or more alcohol binge episodes were reported between October 2020-January 2021 in 19.3% of participants and elevated overall alcohol consumption was reported by 21.6% of participants. Higher odds of elevated alcohol consumption occurred in women and those following more social distancing measures. The odds of binge drinking or elevated alcohol consumption in those using both marijuana and tobacco (aOR/ adjusted odds ratio:18.9, 95% CI = 8.5, 42.2, and aOR:3.9, 95% CI = 1.7, 8.6, respectively) were higher compared to those using neither. Similarly, the odds of binge drinking or elevated alcohol consumption in those using tobacco only (aOR:4.7, 95% CI = 2.9, 7.7 and aOR: 2.0, 95% CI = 1.1, 3.5, respectively) were higher compared to those using neither.Conclusions: This study found high rates of alcohol use and bingeing during the COVID-19 pandemic. Offering collaborative, culturally sensitive, and affordable support services are important components of intervention and preparation for future stressful events on local, as well as global levels.

Cancer statistics for Asian Americans, Native Hawaiians, and Pacific Islanders, 2016: Converging incidence in males and females.

Cancer is the leading cause of death among Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPIs). In this report, the American Cancer Society presents AANHPI cancer incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among AANHPIs in 2016, there will be an estimated 57,740 new cancer cases and 16,910 cancer deaths. While AANHPIs have 30% to 40% lower incidence and mortality rates than non-Hispanic whites for all cancers combined, risk of stomach and liver cancers is double. The male-to-female incidence rate ratio among AANHPIs declined from 1.43 (95% confidence interval, 1.36-1.49) in 1992 to 1.04 (95% confidence interval, 1.01-1.07) in 2012 because of declining prostate and lung cancer rates in males and increasing breast cancer rates in females. The diversity within the AANHPI population is reflected in the disparate cancer risk by subgroup. For example, the overall incidence rate in Samoan men (526.5 per 100,000) is more than twice that in Asian Indian/Pakistani men (216.8). Variations in cancer rates in AANHPIs are related to differences in behavioral risk factors, use of screening and preventive services, and exposure to cancer-causing infections. Cancer-control strategies include improved use of vaccination and screening; interventions to increase physical activity and reduce excess body weight, tobacco use, and alcohol consumption; and subgroup-level research on burden and risk factors.

18F-FDG gallbladder uptake: observation from a total-body PET/CT scanner.

BACKGROUND: Total-body positron emission tomography/computed tomography (PET/CT) scanners are characterized by higher signal collection efficiency and greater spatial resolution compared to conventional scanners, allowing for delayed imaging and improved image quality. These advantages may also lead to better detection of physiological processes that diagnostic imaging professionals should be aware of. The gallbladder (GB) is not usually visualized as an 18F-2-fluorodeoxyglucose (18F-FDG)-avid structure in routine clinical PET/CT studies; however, with the total-body PET/CT, we have been increasingly visualizing GB activity without it being involved in an inflammatory or neoplastic process. The aim of this study was to report visualization rates and characteristics of GB 18F-FDG uptake observed in both healthy and oncological subjects scanned on a total-body PET/CT system. MATERIALS AND METHODS: Scans from 73 participants (48 healthy and 25 with newly diagnosed lymphoma) who underwent 18F-FDG total-body PET/CT were retrospectively reviewed. Subjects were scanned at multiple timepoints up to 3 h post-injection. Gallbladder 18F-FDG activity was graded using liver uptake as a reference, and the pattern was qualified as present in the wall, lumen, or both. Participants' characteristics, such as age, sex, body-mass index, blood glucose, and other clinical parameters, were collected to assess for any significant correlation with GB 18F-FDG uptake. RESULTS: All 73 subjects showed GB uptake at one or more imaging timepoints. An increase in uptake intensity overtime was observed up until the 180-min scan, and the visualization rate of GB 18F-FDG uptake was 100% in the 120- and 180-min post-injection scans. GB wall uptake was detected in a significant number of patients (44/73, 60%), especially at early timepoint scans, whereas luminal activity was detected in 71/73 (97%) subjects, especially at later timepoint scans. No significant correlation was found between GB uptake intensity/pattern and subjects' characteristics. CONCLUSION: The consistent observation of GB 18F-FDG uptake recorded in this study in healthy participants and subjects with a new oncological diagnosis indicates that this is a normal physiologic finding rather than representing an exception.

Effect of a media intervention on hepatitis B screening among Vietnamese Americans.

Objective: There is a lack of controlled studies of community-wide interventions to increase screening for hepatitis B (HBV) among Asian Americans, particularly Vietnamese Americans, who disproportionately suffer from HBV-related illnesses. The objective of our study was to develop, implement, and evaluate the effectiveness of a media campaign to promote HBV screening among Vietnamese Americans.Design: We designed and implemented a three-year media campaign promoting HBV screening among Vietnamese Americans. Evaluation consisted of cross-sectional pre- and post-intervention population-based telephone surveys of Vietnamese Americans adults age 18-64 who spoke English or Vietnamese and lived in the Northern California (intervention) or Greater Washington, D.C. (comparison) communities in 2007 or 2011. Statistical analysis was completed in 2012. The main outcome was self-report of HBV testing, defined as participants answering 'Yes' to the question: 'Have you ever had a blood test to check for hepatitis B?'Results: The sample sizes at pre- and post-intervention were 1,704 and 1,666, respectively. Both communities reported increased exposure to HBV-related booklets, radio and television advertisements, and websites. Only the intervention community reported increased exposure to newspaper elements. HBV screening increased in both communities (intervention: 65.3% to 73.1%, p < 0.01, comparison: 57.7% to 66.0%, p < 0.01). In multivariable analyses, there was no intervention effect. In both communities, exposure to media elements (Odds Ratio 1.26 [95% Confidence Interval: 1.21, 1.31] for each additional element) was significantly associated with screening.Conclusions: Among Vietnamese Americans in 2 large communities, HBV screening rates were sub-optimal. Screening increased in both the intensive media intervention and comparison communities, and exposure to HBV-related media messages was associated with increased screening. Efforts to address HBV screening among Vietnamese Americans should include mass media messaging.

Healthcare Disparities Identified Between Hmong and Other Asian Origin Groups Living with Chronic Hepatitis B Infection in Sacramento County 2014-2017.

Chronic hepatitis B (CHB) disproportionately affects non-US born Asians. The Hmong have been shown to have the highest rates of CHB and mortality from liver cancer compared to other Asian groups. From September 2014 to September 2017, testing for CHB within Sacramento County was conducted through community-based testing events and an electronic health record alert that identified Asian patients by surname. Demographic and laboratory data were collected for analysis and patients were followed through the study period to assess linkage to care and treatment to compare differences between Asian origin groups. Of 4350 patients tested for CHB, 318 (7.3%) were HBsAg positive, including 90 Chinese, 47 Hmong, and 101 Vietnamese. Hmong were more likely to have Medicaid insurance compared to other Asian origin groups (15%, p < 0.001). Hmong had significantly lower rates of hepatitis B DNA testing (p < 0.001), referral to hepatology (p < 0.001), attendance of first (p < 0.001) and second medical visit (p = 0.0003), and lower rates of antiviral treatment compared to other Asian origin groups. Hmong also had the highest proportion of non-English speakers (p < 0.001). Hmong patients in the Sacramento CHB testing and linkage to care program experience socioeconomic disadvantages compared to Vietnamese and Chinese patients. These factors may contribute to decreased linkage of care and decreased anti-viral treatment rates for CHB.

Effect of an Educational Video to Increase Calls and Screening into an Anal Cancer Clinical Trial Among HIV+ Hispanics in PR: Results from a Randomized Controlled Behavioral Trial.

Anal cancer incidence is higher in persons living with HIV/AIDS (PLWHA) than in the general population. Participation of PLWHA in anal cancer clinical trials (CTs) is essential; Hispanic PLWHA are underrepresented in CTs. We conducted a behavioral CT among 305 PLWHA in Puerto Rico to measure the efficacy of an educational video in increasing calls and screening into an anal cancer CT. Participants received printed educational materials on anal cancer and CTs; the intervention group also received an educational video. Outcome assessment based on follow-up interviews showed that printed materials increased awareness about CTs and high-resolution anoscopy (HRA), and willingness to participate in an anal cancer CT in both groups. However, the addition of the video increased the likelihood of participants to call the CT for orientation (RRadjusted = 1.66, 95% CI 1.00-2.76; p = 0.05) and pre-screening evaluation (RRadjusted = 1.70, 95% CI 0.95-3.03; p = 0.07). This intervention could help increase participation of Hispanics into anal cancer-related CTs.

Time, trust, and transparency: Lessons learned from collecting blood biospecimens for cancer research from the Asian American community.

BACKGROUND: Biospecimens from racially diverse groups are needed to advance cancer research. The Asian American Cancer Education Study was developed to increase the number and proportion of blood biospecimen donations from Asian Americans for cancer research. METHODS: The authors' targeted approach included 2 types of community engagement, in-reach (within institution to Asian American patients with cancer) and outreach (external to institution to the general Asian American community). Participants received in-language biospecimen education followed by the opportunity to donate blood biospecimens. Outreach participants donated through our community biospecimen blood drives, and in-reach participants consented to donating an extra tube of blood during their routine blood draws as a patient. Donated blood biospecimens were spun down to serum and plasma to be stored in a biorepository or were sent to the laboratory to test for cancer-related risk factors. RESULTS: Three hundred eighty-eight Asian Americans donated 1127 blood biospecimens for cancer research. Four hundred twenty tubes of plasma and serum are currently being stored at the cancer center's biorepository, 39 tubes have been used for cancer genomic research, and 668 tubes were used to characterize cancer-related risk factors. CONCLUSIONS: Building upon the past decade of the National Cancer Institute-funded Asian American Network for Cancer Awareness, Research, and Training's foundation of trust and service among Asian Americans, researchers were able to leverage relationships not only to introduce the idea of biospecimen contribution to the community but to also exceed expectations with regard to the quantity of blood biospecimens collected from Asian Americans.

The Asian American Network for Cancer Awareness, Research, and Training (AANCART)'s contributions toward reducing Asian American cancer health disparities, 2000-2017.

BACKGROUND: In 2000 and in 2 subsequent 5-year cycles, the National Cancer Institute funded grantees on a regional and national basis to address community needs for cancer awareness, research, and training. The Asian American Network for Cancer Awareness, Research and Training (AANCART) is fortunate to have been funded since 2000 to focus on mitigating cancer health disparities facing Asian Americans residing primarily in California and Hawaii. This article highlights AANCART's achievements with respect to the original specific aims and unanticipated outcomes in its most recent funded cycle. METHODS: Sources included reports to the National Cancer Institute and peer-reviewed articles as well as the insights of the 3 principal investigators. RESULTS: All aims of the original application (infrastructure, outreach, research, and training) were attained or exceeded. Most distinctive was the completion and publication of 8 randomized controlled trials to address Asian American cancer health disparities and its nurture of 14 new and early stage investigators who have been productive in terms of research career trajectories. CONCLUSIONS: AANCART is contributing to mitigating Asian American cancer health disparities by catalyzing academic and community collaborations that have resulted in linguistically specific and culturally tailored educational products, scientifically rigorous interventions addressed at cancer risk factors, and nurturing new and early stage Asian American cancer investigators.

Impact of a cancer education seminar on knowledge and screening intent among Chinese Americans: Results from a randomized, controlled, community-based trial.

BACKGROUND: Cancer is the leading cause of death for Asian Americans. The authors evaluated the status of cancer prevention for Chinese Americans in San Francisco, which has had years of cancer prevention efforts. METHODS: Through a community-based clinic serving Chinese Americans, a randomized, controlled trial (n = 395) was conducted among participants who attended either a cancer prevention seminar or biospecimen education seminar. Changes in knowledge, attitudes, and screening completion/intent were measured across and between seminar groups. RESULTS: Participants were mostly women who had low acculturation and education levels. Over two-thirds to almost all participants knew about modifiable risk factors for cancer and that screening tests were available, including for lung cancer. The majority of women had already completed mammography and Papanicolaou (Pap) tests. Approximately one-half reported having completed colorectal cancer screening, prostate screening, or hepatitis B screening. Most were nonsmokers, but about one-half "strongly agreed" that they would want a test for tobacco smoke exposure. After the cancer prevention seminar, significant increases within group were noted for knowledge (eating healthy foods, from 93.1% to 97.7% [P = .0002]; secondhand smoke causes cancer, from 66.3% to 74.8% [P = .04]) and for screening completion/intent (colorectal cancer, from 58.1% to 64.5% [P = .002] cervical cancer, from 72.9% to 75.5% [P = .04]) and there was a trend toward an increase for prostate cancer (from 50.0% to 61.1%; P = .10). There was a significant change between groups for eating healthy foods (P = .004). CONCLUSIONS: The current reports documents the gains in cancer prevention among Cantonese-speaking Chinese Americans, fostered by academic, community, and public health efforts. A community-based seminar demonstrated improvement in some cancer knowledge or screening intent and opportunities for continued efforts. Cancer 2018;124:1622-30. © 2018 American Cancer Society.

High frequency of the PNPLA3 rs738409 [G] single-nucleotide polymorphism in Hmong individuals as a potential basis for a predisposition to chronic liver disease.

BACKGROUND: An exploratory study was performed to determine the prevalence of the patatin-like phospholipase domain-containing protein 3 (PNPLA3) rs78409 [G] allele among the Hmong as a risk factor for nonalcoholic fatty liver disease (NAFLD). NAFLD/nonalcoholic steatohepatitis is the world's most common chronic liver disease and is expected to replace viral hepatitis as the leading cause of cirrhosis and potential precursor to hepatocellular carcinoma (HCC). Of all populations in California, the Hmong experience the highest risk of death from HCC and the highest prevalence of metabolic syndrome risk factors among Asians that predispose them to NAFLD. Here a genetic explanation was sought for the high rates of chronic liver disease among the Hmong. The literature pointed to the PNPLA3 rs738409 [G] allele as a potential genetic culprit. METHODS: Cell-free DNA was isolated from 26 serum samples previously collected in community settings. Quantitative polymerase chain reaction-based single-nucleotide polymorphism (SNP) genotyping was performed with a validated TaqMan SNP genotyping assay, and results were analyzed with TaqMan Genotyper software. RESULTS: The PNPLA3 rs738409 [C>G] variant occurred at a frequency of 0.46 (12 of 26; 95% confidence interval, 0.27-0.67). This carrier rate would rank the Hmong as the third highest population in the 1000 Genomes Project. CONCLUSIONS: Although this small sample size limits the generalizability, the high frequency rates of this allele along with the presence of metabolic syndrome risk factors warrant further studies into the etiology of NAFLD among the Hmong.

Community-Based Services to Improve Testing and Linkage to Care Among Non-U.S.-Born Persons with Chronic Hepatitis B Virus Infection - Three U.S. Programs, October 2014-September 2017.

Among an estimated 850,000 to 2.2 million persons with chronic hepatitis B virus (HBV) infection in the United States, 70% are non-U.S.-born (1,2). All patients require linkage to care, and approximately 20%-40% require antiviral treatment (3). Without treatment, one in four persons chronically infected with HBV will die prematurely from liver failure, liver cirrhosis, or hepatocellular carcinoma (4). To mitigate morbidity and mortality, CDC funded a cooperative agreement to develop hepatitis B testing and linkage-to-care programs serving non-U.S.-born persons during October 2014-September 2017. This report describes each program's operational services and partnerships with primary care centers, community-based organizations, and public health departments to recruit non-U.S.-born persons for HBV testing using the hepatitis B surface antigen (HBsAg) and link those whose test results were positive to HBV-directed care (medical visit attendance with monitoring of HBV DNA and liver enzyme tests). Among 10,152 program participants, 757 (7.5%) were HBsAg-positive, indicative of chronic HBV infection; among these, 643 (85%) attended ≥1 medical visit, 587 (78%) received HBV-directed care, and 137 (18%) were prescribed antiviral treatment. Among 273 household contacts of HBsAg-positive persons, 39 (14%) had positive test results for HBsAg. Prevalence of current HBV infection was high in this non-U.S.-born population and among household and sexual contacts of HBV-infected persons. HBV testing and linkage to care can be achieved through partnerships with community organizations, health centers, and public health departments.

Lay health educators and print materials for the promotion of colorectal cancer screening among Korean Americans: A randomized comparative effectiveness study.

BACKGROUND: Colorectal cancer (CRC) is the second most commonly diagnosed cancer among Korean American men and women. Although CRC screening is effective in reducing the burden of this disease, studies have shown that Korean Americans have low screening rates. METHODS: The authors conducted a 2-arm cluster randomized controlled trial comparing a brochure (print) with a brochure and lay health educator (LHE) outreach (print + LHE) in increasing CRC screening rates among Korean American individuals. Self-administered written surveys at baseline and at 6 months assessed knowledge of CRC and its screening, ever screening, and being up to date with screening. RESULTS: A total of 28 LHEs recruited 348 participants aged 50 to 75 years from their social networks. Significant percentages of participants reported not having health insurance (29.3%) or a usual source of care (35.6%). At 6 months postintervention, the print + LHE participants had a greater increase in knowledge compared with those in the print arm (P = .0013). In multivariable analyses, both groups had significant increases in ever screening (print plus LHE: odds ratio [OR], 1.60 [95% confidence interval (95% CI), 1.26-2.03] and print: OR, 1.42 [95% CI, 1.10-1.82]) and being up to date with screening (print plus LHE: OR, 1.63 [95% CI, 1.23-2.16] and print: OR, 1.40 [95% CI, 1.04-1.89]). However, these increases did not differ significantly between the study arms. Having insurance and having seen a provider within the past year were found to be positively associated with screening. CONCLUSIONS: Compared with a brochure, LHE outreach yielded greater increases in knowledge but resulted in similar increases in CRC screening in a Korean American population with barriers to health care access. More work is needed to appropriately address logistical and system barriers in this community. Cancer 2017;123:2705-15. © 2017 American Cancer Society.

Lay health educators increase colorectal cancer screening among Hmong Americans: A cluster randomized controlled trial.

BACKGROUND: Asian Americans have lower colorectal cancer (CRC) screening rates than non-Hispanic white individuals. Hmong Americans have limited socioeconomic resources and literacy. The current randomized controlled trial was conducted to determine whether bilingual/bicultural lay health educator (LHE) education could increase CRC screening among Hmong Americans. METHODS: A cluster randomized controlled trial was conducted among Hmong Americans in Sacramento, California. LHEs and recruited participants were randomized to intervention or control groups. The intervention group received CRC education over 3 months delivered by an LHE. The control group received education regarding nutrition and physical activity delivered by a health educator. The outcomes were changes in self-reported ever-screening and up-to-date CRC screening after 6 months. RESULTS: All 329 participants were foreign-born with mostly no formal education, limited English proficiency, and no employment. The majority of the participants were insured and had a regular source of health care. The intervention group experienced greater changes after the intervention than the control group for ever-screening (P = .068) and being up-to-date with screening (P<.0001). In multivariable regression analyses, the intervention group demonstrated a greater increase than the control group in reporting ever-screening (adjusted odds ratio, 1.73; 95% confidence interval, 1.07-2.79) and being up-to-date with screening (adjusted odds ratio, 1.71; 95% confidence interval, 1.26-2.32). Individuals who had health insurance were found to have >4 times the odds of receiving screening, both ever-screening and up-to-date screening. A higher CRC knowledge score mediated the intervention effect for both screening outcomes. CONCLUSIONS: A culturally and linguistically appropriate educational intervention delivered by trained LHEs was found to increase CRC screening in an immigrant population with low levels of education, employment, English proficiency, and literacy.

Diabetes Prevalence and Risk Factors in Four Asian American Communities.

Our objective was to estimate the prevalence of diabetes and pre-diabetes and the risk associated with BMI above the Asian cut-point of 23 in 4 Asian American communities. In a convenience sample of 981 Chinese, Hmong, Korean, and Vietnamese Americans in Sacramento County, California we measured hemoglobin A1c (HbAlc), height, weight, and waist circumference. Diabetes was defined as self-reported diabetes diagnosis or HbA1c ≥ 6.5 %, and pre-diabetes as HbAlc 5.7-6.4 % with no diabetes diagnosis. We computed age-standardized prevalence of diabetes, pre-diabetes, and BMI and waist circumference above standard and Asian cut-points, and developed multivariable models of the association of diabetes and pre-diabetes with BMI and waist circumference. The 4 ethnic groups differed substantially with respect to diabetes prevalence, BMI, and waist circumference. Hmong had the highest prevalence of diabetes (15.0 %, 95 % confidence interval [CI] 10.7-19.4 %). Diabetes and pre-diabetes were associated with BMI ≥ 25 (diabetes: odds ratio [OR] 3.4, 95 % CI 2.1-5.7; pre-diabetes: OR 4.0, 95 % CI 2.7-5.8) or between 23 and 25 (diabetes: OR 1.8, 95 % CI 1.0-3.1; pre-diabetes: OR 1.6, 95 % CI 1.0-2.4). When waist circumference was added to the model, BMI effects were attenuated, and waist circumference ≥40 inches (men) or ≥35 inches (women) was associated with increased risk of diabetes (OR 3.2, 95 % CI 1.6-6.2) and pre-diabetes (OR 1.7, 95 % CI 1.0-2.9). Our findings support the use of a BMI cut-point of 23 and the importance of central adiposity as a risk factor for diabetes in Asians. Diabetes risk reduction interventions for Asians are essential.

Twenty years post-NIH Revitalization Act: enhancing minority participation in clinical trials (EMPaCT): laying the groundwork for improving minority clinical trial accrual: renewing the case for enhancing minority participation in cancer clinical trials.

BACKGROUND: The National Institutes of Health (NIH) Revitalization Act of 1993 mandated the appropriate inclusion of minorities in all NIH-funded research. Twenty years after this act, the proportion of minority patients enrolled in cancer clinical trials remains persistently low. Clinical trials are vehicles for the development and evaluation of therapeutic and preventive agents under scientifically rigorous conditions. Without representation in trials, it is projected that disparities in the cancer burden for minorities will increase. METHODS: For this review article, the authors counted the frequency with which minorities were the primary focus of National Cancer Institute-sponsored clinical trials, examined citations from the PubMed database focusing on the search terms "NIH Revitalization Act of 1993" and "enhancing minority accrual to cancer clinical trials," and supplemented the review with their expertise in NIH-funded research related to minority accrual in cancer clinical trials. RESULTS: The reporting and analyses of data based on minorities in clinical trials remain inadequate. Less than 2% of the National Cancer Institute's clinical trials focus on any racial/minority population as their primary emphasis. The current review of the literature indicated that the percentage of authors who reported their study sample by race/ethnicity ranged from 1.5% to 58%, and only 20% of the randomized controlled studies published in a high-impact oncology journal reported analyzing results by race/ethnicity. Proportionately greater population increases in minorities, accompanied by their persistent and disproportionate cancer burden, reinforce the need for their greater representation in clinical trials. CONCLUSIONS: Renewing the emphasis for minority participation in clinical trials is warranted. Policy changes are recommended.

Five National Cancer Institute-designated cancer centers' data collection on racial/ethnic minority participation in therapeutic trials: a current view and opportunities for improvement.

BACKGROUND: To ensure that National Institutes of Health-funded research is relevant to the population's needs, specific emphasis on proportional representation of minority/sex groups into National Cancer Institute (NCI) cancer centers' clinical research programs is reported to the NCI. METHODS: EMPaCT investigators at 5 regionally diverse comprehensive cancer centers compared data reported to the NCI for their most recent Cancer Center Support Grant competitive renewal to assess and compare the centers' catchment area designations, data definitions, data elements, collection processes, reporting, and performance regarding proportional representation of race/ethnicity and sex subsets. RESULTS: Cancer centers' catchment area definitions differed widely in terms of their cancer patient versus general population specificity, levels of specificity, and geographic coverage. Racial/ethnic categories were similar, yet were defined differently, across institutions. Patients' socioeconomic status and insurance status were inconsistently captured across the 5 centers. CONCLUSIONS: Catchment area definitions and the collection of patient-level demographic factors varied widely across the 5 comprehensive cancer centers. This challenged the assessment of success by cancer centers in accruing representative populations into the cancer research enterprise. Accrual of minorities was less than desired for at least 1 racial/ethnic subcategory at 4 of the 5 centers. Institutions should clearly and consistently declare their primary catchment area and the rationale and should report how race/ethnicity and sex are defined, determined, collected, and reported. More standardized, frequent, consistent collection, reporting, and review of these data are recommended, as is a commitment to collecting socioeconomic data, given that socioeconomic status is a primary driver of cancer disparities in the United States.

Developing theoretically based and culturally appropriate interventions to promote hepatitis B testing in 4 Asian American populations, 2006-2011.

INTRODUCTION: Hepatitis B infection is 5 to 12 times more common among Asian Americans than in the general US population and is the leading cause of liver disease and liver cancer among Asians. The purpose of this article is to describe the step-by-step approach that we followed in community-based participatory research projects in 4 Asian American groups, conducted from 2006 through 2011 in California and Washington state to develop theoretically based and culturally appropriate interventions to promote hepatitis B testing. We provide examples to illustrate how intervention messages addressing identical theoretical constructs of the Health Behavior Framework were modified to be culturally appropriate for each community. METHODS: Intervention approaches included mass media in the Vietnamese community, small-group educational sessions at churches in the Korean community, and home visits by lay health workers in the Hmong and Cambodian communities. RESULTS: Use of the Health Behavior Framework allowed a systematic approach to intervention development across populations, resulting in 4 different culturally appropriate interventions that addressed the same set of theoretical constructs. CONCLUSIONS: The development of theory-based health promotion interventions for different populations will advance our understanding of which constructs are critical to modify specific health behaviors.

"You Don't Know If It's the Truth or a Lie": Exploring Human Papillomavirus (HPV) Vaccine Hesitancy among Communities with Low HPV Vaccine Uptake in Northern California.

BACKGROUND: Vaccine hesitancy, delaying or refusing to vaccinate despite the availability of vaccines, impedes the progress of achieving optimal HPV vaccine coverage. Little is known about the sources of human papillomavirus (HPV) vaccine hesitancy among racially/ethnically and geographically diverse communities. The purpose of this paper is to explore HPV vaccine hesitancy among rural, Slavic, and Latino communities that reside in counties with low HPV vaccine uptake rates. METHODS: Key informant interviews and focus groups were conducted with rural, Slavic, and Latino communities that reside within counties in California that have low HPV vaccine up to date rates (16-25%). Qualitative data were transcribed verbatim and analyzed using inductive and deductive thematic analysis. RESULTS: A total of seven focus groups and 14 key informant interviews were conducted with 39 individuals from seven California counties. Salient themes that contributed to HPV vaccine hesitancy included the following: social media and the anti-vaccination movement; a strong belief in acquiring immunity naturally; prior vaccine experiences; and vaccine timing concerns. Participants suggested the provision of culturally appropriate, in-language, in-person easy to understand HPV vaccine education to mitigate HPV vaccine hesitancy. CONCLUSIONS: Our findings can inform future interventions to increase HPV vaccine uptake among hesitant communities.

Association Between COVID-19 and Planned and Postponed Cancer Screenings Among American Indian Adults Residing in California and Oklahoma, March-December 2020.

OBJECTIVE: Little is known about how the COVID-19 pandemic affected cancer screenings among American Indian people residing in California and Oklahoma, 2 states with the largest American Indian populations. We assessed rates and factors associated with cancer screenings among American Indian adults during the pandemic. METHODS: From October 2020 through January 2021, we surveyed 767 American Indian adults residing in California and Oklahoma. We asked participants whether they had planned to obtain screenings for breast cancer, cervical cancer, and colorectal cancer (CRC) from March through December 2020 and whether screening was postponed because of COVID-19. We calculated adjusted odds ratios (AORs) for factors associated with reasons for planned and postponed cancer screening. RESULTS: Among 395 participants eligible for breast cancer screening, 234 (59.2%) planned to obtain the screening, 127 (54.3%) of whom postponed it. Among 517 participants eligible for cervical cancer screening, 357 (69.1%) planned to obtain the screening, 115 (32.2%) of whom postponed it. Among 454 participants eligible for CRC screening, 282 (62.1%) planned to obtain CRC screening, 80 of whom (28.4%) postponed it. In multivariate analyses, women who lived with a child (vs did not) had lower odds of planning to obtain a breast cancer screening (AOR = 0.6; 95% CI, 0.3-1.0). Adherence to social distancing recommendations was associated with planning to have and postponement of cervical cancer screening (AOR = 7.3; 95% CI, 0.9-58.9). Participants who received (vs did not receive) social or financial support had higher odds of planning to have CRC screening (AOR = 2.0; 95% CI, 1.1-3.9). CONCLUSION: The COVID-19 pandemic impeded completion of cancer screenings among American Indian adults. Interventions are needed to increase the intent to receive evidence-based cancer screenings among eligible American Indian adults.
