RESUMO
Introduction: Native Hawaiian people have higher rates of illness and death related to cardiovascular disease (CVD) than non-Hispanic White people. Research in other populations has shown that individual-level CVD risk factors (ie, high-fat diet, physical inactivity, obesity, and tobacco use) are associated with neighborhood characteristics (ie, social cohesion, walkability, availability of healthy food, and safety). This association has yet to be examined among Native Hawaiians. Methods: We conducted a cross-sectional survey of community-dwelling Native Hawaiian people in 2020. Three multiple regression models and 1 logistic regression model were assessed. Each model included individual-level CVD risk factors, age, sex, education, income, and neighborhood characteristics. Results: The regression models for body mass index (BMI) and physical activity showed significant results. The BMI model (R2 = 0.22, F = 4.81, P < .001) demonstrated that age, sex, education level, physical activity, and percentage of fat in the diet were significantly related to BMI. The availability of healthy foods had a significant, independent relationship with BMI (standardized ß = -1.47, SE = 0.53, P = .01). The physical activity model (R2 = 0.21, F = 4.46, P < .001) demonstrated that age, sex, education, and BMI were significantly related to physical activity. None of the neighborhood characteristics had significant, independent relationships to physical activity. Conclusions: We found that neighborhood-level factors improved the model's ability to explain variance in BMI. Efforts to decrease BMI would benefit from improving the availability of healthy foods in neighborhoods, a finding supported by research in other populations.

Medical student knowledge and opinions of clinical research have important ramifications for how likely they will be to refer patients into clinical trials as practicing physicians. This study examined students understanding, knowledge, and attitudes about clinical trials at the start of medical school and after completion of a multi-faceted intervention designed to increase medical students' confidence in understanding and explaining clinical trials during the pre-clinical and clinical years. Medical students were surveyed about their knowledge of and attitudes toward clinical trials in their first (N = 724) and third (N = 191) years of medical school. During the intervening years, students attend a lecture delivered by University of Hawai 'i Cancer Center faculty, were provided a resource manual from National Cancer Institute, participated in two problem-based learning clinical scenarios, and completed an optional practicum. After completing the comprehensive clinical trials education, there were significant increases in student understanding and knowledge and a decrease in student perception that clinical trials exploit participants. Most students agreed or strongly agreed that inclusion of clinical trials in the curriculum was important and would influence their future practice. Integration of clinical trials education into the medical school curriculum improved students' understanding of clinical research, their ability to communicate the clinical trials process, and confidence in conducting, referring to, and locating clinical trials. Medical students appreciate the importance of clinical trials in advancing medicine and medical education. Further integration of clinical trials education and opportunities to engage in research during medical school are warranted to address students' uncertainty about the benefits of participation for patients.

OBJECTIVE/DESIGN: The University of Hawai'i Cancer Center works with academic and community partners to examine health disparities and inequities that persist among Pacific Island Populations through the Pacific Island Partnership for Cancer Health Equity (PIPCHE). The Partnership's Community Outreach Core (COC) assists and promotes cancer research and helps to ensure the integration of historically excluded community perspectives by utilizing community-engaged and culturally-grounded approaches to reduce cancer burdens. However, cancer health disparities among Filipinos demonstrate a need for cancer-control initiatives within this community. SAMPLE/MEASUREMENTS: COC staff conducted five semi-structured key informant interviews with Filipino nurse and healthcare leaders in Hawai'i to establishpartnerships with the community, as well as provide community-driven guidance for future cancer prevention and control efforts. RESULTS: The informants provided recommendations for COC community engagement, relationship building, and future areas of directed cancer focus. The interviews also initiated relationship-building and community collaborations for directed cancer education and resources within Filipino communities. CONCLUSION: The themes uncovered from the interviews provided guidance on how to begin addressing cancer concerns, and led to the informants' subsequent membership in our Outreach Advisory Council to engage in future collaboration with the Filipino community and a framework for future community-engaged cancer prevention efforts.

PURPOSE: To examine cancer patients and their family caregivers' perspectives of care coordination (CC) using a dyadic research design. METHODS: In this pilot cross-sectional study, 54 patient-family caregiver dyads completed a validated care coordination instrument (CCI) and its parallel family caregiver instrument (CCICG) from June to September 2019. The sample available for analysis included data from 32 dyads, which included patients receiving active therapy for any cancer type and their primary family caregivers aged 18 years or older. Mixed regression models were used to examine dyadic differences. RESULTS: The overall family caregiver scores demonstrated a bimodal pattern; thus, we conducted analyses using aggregate data as well as by highCG and lowCG subgroups. Among dyads in the lowCG subgroup, family caregivers reported significantly lower scores than patients on the total CCI and the three CC domains: Communication, Navigation, and Operational. Caregiver gender, the absence of a patient navigator, and practice setting (hospital-based ambulatory) significantly predicted dyadic differences in the lowCG subgroup. In item-level analyses, family caregivers in the lowCG subgroup reported lower scores than patients on the items related to patient-physician communication. CONCLUSION: A subgroup of family caregivers reported poorer perception of CC than patients, suggesting that those family caregivers and providers may benefit from intervention. Further understanding of patient-family caregiver dyads' perspectives of CC can inform development of strategies to integrate family caregivers into the cancer care team, develop effective CC interventions for family caregivers, and contribute to improved quality and value of cancer care.

BACKGROUND: Although the importance of care coordination (CC) is well-recognized, cancer patients often receive poorly coordinated care across varied care settings and different oncology providers. Efforts to improve cancer care are hampered by lack of adequate measures. In this two-part, mixed-method study, we describe the development, refinement, and validation of a new care coordination instrument (CCI) designed to assess cancer patients' perception of CC. METHODS: In Study 1, an initial CCI was developed incorporating questions based on literature review. The items were then modified following four field tests conducted in a large academic hospital with oncology nurses (n = 20) and cancer patients (n = 120). This modified instrument was used to determine whether the CCI was able to distinguish CC between two practices (30 GI and 30 myeloma patients) within the same hospital setting. In Study 2, 68 patients receiving community-based care participated in seven focus groups. Based on these discussions, the CCI items were again refined, and psychometric evaluation was conducted to assess the quality of the instrument. RESULTS: Based on field tests, 3 domains of the CCI, Communication, Navigation, and Operational, were defined as critical components of CC. The Operational domain evaluates efficiency of care and is unique to this CCI. The field test demonstrated that GI patients reported significantly better CC Overall and for the Communication and Navigation domains (all p < .05). In Study 2, patients expressed concordance with the CCI items and their CC experiences, establishing validity of the CCI. Qualitative analysis of the focus group discussions indicated that the items with the highest frequencies of participants' comments were related to the concepts of Navigator, Team, Survey, and Communication. Quantitative analysis identified items with a limited response range or high rates of "neutral" responses; accordingly, those items were removed. The final CCI survey is a 29 item, multiple-choice questionnaire with excellent reliability, Cronbach's α = .922. CONCLUSIONS: We developed a novel, patient-centered tool with excellent psychometric properties that can be utilized across varied practice settings to assess patients' perception of cancer care coordination. TRIAL REGISTRATION: Not required; retrospectively registered ClinicalTrials.gov NCT03594006 20 July 2018.

Resilience has conventionally focused on an individual's ability to overcome adversity. Recent research expands on this definition, making resilience a multi-dimensional construct. Native Hawaiians experience health disparities compared to the general population of Hawai'i. Despite the pressing need to address health disparities, minimal research examines resilience factors that serve as buffers for adverse experiences of Native Hawaiians. The purpose of this study was to estimate psychometric properties of scales that measured resilience-based factors through multiple levels using higher-order confirmatory factor analyses (CFA) and ascertain if this construct of resilience mediated or moderated adversity experienced by a sample of Native Hawaiians. Participants included 125 adults who participated in the Hawaiian Homestead Health Survey. Based on higher-order CFA, resilience comprised internal assets measured by hope, satisfaction with life, and environmental mastery, and external resources measured by social support and Native Hawaiian cultural identity. Results of the structural equation models were consistent with literature focusing on resiliency and health. Findings emphasized the importance of enhancing resilience by considering strengths and resources on the individual, interpersonal, and community levels. Findings also demonstrated the need to address adversity factors directly, with a specific need of addressing socio-economic status factors. According to structural equation models, resilience slightly mediated and moderated the effect of adversity related to socio-economic status. These findings have implications for future research exploring resilience as a mediator or moderator of adversity among Native Hawaiians and emphasize a multi-faceted construct of resilience to promote better health outcomes.

Introduction: Prior to the US Food and Drug Administration's (FDA) regulation of electronic cigarettes and warning statements related to nicotine addiction, there was no critical examination of manufacturer/distributor voluntary practices that could potentially inform FDA actions aimed to protect consumers. This study examined the content of warning statements and safety characteristics of electronic cigarette liquid bottles using a national sample. Methods: Research staff randomly selected four electronic cigarette liquid manufacturers/distributors from four US geographic regions. Staff documented the characteristics of product packaging and content of warning statements on 147 electronic cigarette liquids (0-30 mg/ml of nicotine) purchased online from 16 manufacturers/distributors in April of 2016. Results: Data showed that 97.9% of the electronic cigarette liquid bottles included a warning statement, most of which focused on nicotine exposure rather than health. Only 22.4% of bottles used a warning statement that indicated the product "contained nicotine." Of bottles that advertised a nicotine-based concentration of 12 mg/ml, 26% had a warning statements stated that the product "contains nicotine." None of the statements that indicated that the product "contained nicotine" stated that nicotine was "addictive." All bottles had a safety cap and 12% were in plastic shrink-wrap. Fifty-six percent of the websites had a minimum age requirement barrier that prevented under-aged persons from entering. Conclusions: Most manufacturers/distributors printed a warning statement on electronic cigarette liquid bottles, but avoided warning consumers about the presence and the addictiveness of nicotine. Studies are needed to examine manufacturer/distributor modifications to product packaging and how packaging affects consumer behaviors. Implications: These data can inform future FDA requirements related to the packaging and advertising of e-cigarette liquids; regulation related to the content of warning statements, including exposure warning statements, which are not currently mandated; and requirements on websites or language on packaging to help manufacturers adhere to the minimum age of purchase regulation. The data can also be used to help FDA develop additional guidance on the framing of statements on packaging that helps consumers make informed decisions about purchasing the product or protecting young people from use or unintentional exposure to the product.

Introduction: Sugars are major constituents and additives in traditional tobacco products, but little is known about their content or related toxins (formaldehyde, acetaldehyde, and acrolein) in electronic cigarette (e-cigarette) liquids. This study quantified levels of sugars and aldehydes in e-cigarette liquids across brands, flavors, and nicotine concentrations (n = 66). Methods: Unheated e-cigarette liquids were analyzed using liquid chromatography mass spectrometry and enzymatic test kits. Generalized linear models, Fisher's exact test, and Pearson's correlation coefficient assessed sugar, aldehyde, and nicotine concentration associations. Results: Glucose, fructose and sucrose levels exceeded the limits of quantification in 22%, 53% and 53% of the samples. Sucrose levels were significantly higher than glucose [χ2(1) = 85.9, p < .0001] and fructose [χ2(1) = 10.6, p = .001] levels. Formaldehyde, acetaldehyde, and acrolein levels exceeded the limits of quantification in 72%, 84%, and 75% of the samples. Acetaldehyde levels were significantly higher than formaldehyde [χ2(1) = 11.7, p = .0006] and acrolein [χ2(1) = 119.5, p < .0001] levels. Differences between nicotine-based and zero-nicotine labeled e-cigarette liquids were not statistically significant for sugars or aldehydes. We found significant correlations between formaldehyde and fructose (-0.22, p = .004) and sucrose (-0.25, p = .002) and acrolein and fructose (-0.26, p = .0006) and sucrose (-0.21, p = .0006). There were no significant correlations between acetaldehyde and any of the sugars or any of the aldehydes and glucose. Conclusions: Sugars and related aldehydes were identified in unheated e-cigarette liquids and their composition may influence experimentation in naïve users and their potential toxicity. Implications: The data can inform the regulation of specific flavor constituents in tobacco products as a strategy to protect young people from using e-cigarettes, while balancing FDA's interest in how these emerging products could potentially benefit adult smokers who are seeking to safely quit cigarette smoking. The data can also be used to educate consumers about ingredients in products that may contain nicotine and inform future FDA regulatory policies related to product standards and accurate and comprehensible labeling of e-cigarette liquids.

Given the current emphasis on accurate computational fluid dynamics (CFD) modeling of cardiovascular flows, which incorporates realistic blood vessel geometries and cardiac waveforms, it is necessary to revisit the conventional wisdom regarding the influences of non-Newtonian effects. In this study, patient-specific reconstructed 3D geometries, whole blood viscosity data, and venous pulses postdialysis access surgery are used as the basis for the hemodynamic simulations of renal failure patients with native fistula access. Rheological analysis of the viscometry data initially suggested that the correct choice of constitutive relations to capture the non-Newtonian behavior of blood is important because the end-stage renal disease (ESRD) patient cohort under observation experience drastic variations in hematocrit (Hct) levels and whole blood viscosity throughout the hemodialysis treatment. For this purpose, various constitutive relations have been tested and implemented in CFD practice, namely Quemada and Casson. Because of the specific interest in neointimal hyperplasia and the onset of stenosis in this study, particular attention is placed on differences in nonhomeostatic wall shear stress (WSS) as that drives the venous adaptation process that leads to venous geometric evolution over time in ESRD patients. Surprisingly, the CFD results exhibit no major differences in the flow field and general flow characteristics of a non-Newtonian simulation and a corresponding identical Newtonian counterpart. It is found that the vein's geometric features and the dialysis-induced flow rate have far greater influence on the WSS distribution within the numerical domain.

The surgical creation of vascular accesses for renal failure patients provides an abnormally high flow rate conduit in the patient's upper arm vasculature that facilitates the hemodialysis treatment. These vascular accesses, however, are very often associated with complications that lead to access failure and thrombotic incidents, mainly due to excessive neointimal hyperplasia (NH) and subsequently stenosis. Development of a framework to monitor and predict the evolution of the venous system post access creation can greatly contribute to maintaining access patency. Computational fluid dynamics (CFD) has been exploited to inspect the non-homeostatic wall shear stress (WSS) distribution that is speculated to trigger NH in the patient cohort under investigation. Thereafter, CFD in liaison with a gradient-free shape optimization method has been employed to analyze the deformation modes of the venous system enduring non-physiological hemodynamics. It is observed that the optimally evolved shapes and their corresponding hemodynamics strive to restore the homeostatic state of the venous system to a normal, pre-surgery condition. It is concluded that a CFD-shape optimization coupling that seeks to regulate the WSS back to a well-defined physiological WSS target range can accurately predict the mode of patient-specific access failure.
RESUMO
UNLABELLED: The Guam population offers a unique glimpse into Americans of Pacific Island ancestry and their communication and information-seeking behaviors, experiences, and needs relevant to cancer. National surveys do not typically include the U.S. territories, so there are limited data on the health and cancer information-seeking behaviors of these populations, in which health disparities persist. To fill this information gap, we conducted a survey on health communication in Guam using a modified version of the Health Information National Trends Survey instrument supplemented with items measuring specific cultural factors and communication practices. The results of the survey (N = 511) revealed some differences in health and cancer information-seeking patterns in Guam and the mainland United States. Sociodemographic variables, including sex, age, education, income, and employment, were significantly associated with health and cancer information seeking and Internet use. Levels of trust in various information sources were differentiated in the Guam and mainland U.S. SAMPLES: Logistic regression models revealed differences in factors predicting health and cancer information seeking and Internet use. The results suggest that these health information-seeking patterns and factors should be taken into account when developing communication strategies for more effective prevention and control programs.

Cigarette smoking may be one of the factors contributing to the high levels of cancer-related mortality experienced by certain Asian/Pacific Islander (A/PI) subgroups (e.g., Native Hawaiian). Given the collectivist cultural orientation attributed to A/PI groups, social strategies are recommended for substance abuse or smoking cessation treatment among A/PI. However, research examining how social network characteristics and social support relate to smoking across A/PI subgroups has been lacking. This study investigated the associations between social network characteristics (e.g., size, composition), perceived social support, and recent cigarette use across Native Hawaiian, Filipino, and East Asian (e.g., Japanese, Chinese) young adults (18-35 year old). Cross-sectional, self-report data were collected from N = 435 participants (M age = 25.6, SD = 8.3; 61% women). Ethnic differences were found in a number of pathways linking social network characteristics, perceived social support, and cigarette smoking. Larger network size was strongly associated with higher perceived social support and lower recent cigarette smoking among Native Hawaiians but not Filipinos or East Asians. Higher perceived social support was associated with lower recent smoking among East Asians and Filipinos but not Native Hawaiians. Implications are discussed with regard to smoking prevention and cessation among A/PI.

Anal cancer disproportionately burdens persons living with human immunodeficiency virus (PLHIV) regardless of natal sex, sexual orientation, gender expression, and ethnic identity. Culturally competent communications are recommended to address health disparities, with sociocultural relevance ensured through constituent dialogic processes. Results are presented from six provider focus groups conducted to inform the promotion/education component of a Hawai'i-based project on anal cancer screening tools. Krueger's focus group methodology guided discussion queries. Verbatim transcripts of digitally recorded discussions were analyzed using grounded theory and PEN-3 procedures. Adherence to an audit trail ensured analytic rigor. Grounded theory analysis detected the overall theme of risk and reluctance to anal cancer screening, characterized by anal cancer not being "on the radar" of PLHIV, conflicting attributions of the anus and anal sex, fear of sex-shaming/-blaming, and other interrelated conceptual categories. PEN-3 analysis revealed strategies for destigmatizing anal cancer, through "real talk" (proactive, candid, nonjudgmental discussion) nested in a framework of sexual health and overall well-being, with additional tailoring for relevance to Native Hawaiians/Pacific Islanders, transgender persons, and other marginalized groups. Application of strategies for health practice are specific to the Hawai'i context, yet may offer considerations for developing strengths-based, culturally relevant screening promotion/education with diverse PLHIV in other locales.

OBJECTIVES: We examined biomarkers of tobacco smoke exposure among Native Hawaiians, Filipinos, and Whites, groups that have different lung cancer risk. METHODS: We collected survey data and height, weight, saliva, and carbon monoxide (CO) levels from a sample of daily smokers aged 18-35 (n = 179). Mean measures of nicotine, cotinine, cotinine/cigarettes per day ratio, trans 3' hydroxycotinine, the nicotine metabolite ratio (NMR), and expired CO were compared among racial/ethnic groups. RESULTS: The geometric means for cotinine, the cotinine/cigarettes per day ratio, and CO did not significantly differ among racial/ethnic groups in the adjusted models. After adjusting for gender, body mass index, menthol smoking, Hispanic ethnicity, and number of cigarettes smoked per day, the NMR was significantly higher among Whites than among Native Hawaiians and Filipinos (NMR = 0.33, 0.20, 0.19, P ≤ .001). The NMR increased with increasing White parental ancestry. The NMR was not significantly correlated with social-environmental stressors. CONCLUSIONS: Racial/ethnic groups with higher rates of lung cancer had slower nicotine metabolism than Whites. The complex relationship between lung cancer risk and nicotine metabolism among racial/ethnic groups needs further clarification.

Obesity-associated chronic diseases persist in Samoan populations in the United States. Samoans and African Americans share cultural similarities such as church affiliation, perceptions of weight and body size, and obesity-related health risks. Adapting an effective energy balance intervention originally designed for African Americans--Body and Soul--might be useful in reducing obesity among U.S. Samoans. To determine potential attractiveness and adaptations, we used aspects of grounded theory to analyze key-informant and focus group interviews with 31 purposively selected Samoans in Hawaii. We incorporated participatory features into the research with Samoan community members conducting parts of the study. From interview narratives, we identified relevant themes from Samoan culture, such as "fa'aSamoa", or the Samoan way, and specific energy balance activities to include in an obesity and cancer prevention intervention for U.S.-dwelling Samoans. Our findings describe methods to address health disparities by incorporating culturally appropriate health concepts into existing evidence-based interventions.

Obesity in the United States and Western countries represents a major health challenge associated with an increased risk of metabolic diseases, including cardiovascular disease, hypertension, diabetes, and certain cancers. Our past work revealed a more pronounced obesity-cancer link in certain ethnic groups, motivating us to develop a tailored dietary intervention called the Healthy Diet and Lifestyle 2 (HDLS2). The study protocol is described herein for this randomized six-month trial examining the effects of intermittent energy restriction (5:2 Diet) plus the Mediterranean dietary pattern (IER + MED) on visceral adipose tissue (VAT), liver fat, and metabolic biomarkers, compared to a standard MED with daily energy restriction (DER + MED), in a diverse participant group. Using MRI and DXA scans for body composition analysis, as well as metabolic profiling, this research aims to contribute to nutritional guidelines and strategies for visceral obesity reduction. The potential benefits of IER + MED, particularly regarding VAT reduction and metabolic health improvement, could be pivotal in mitigating the obesity epidemic and its metabolic sequelae. The ongoing study will provide essential insights into the efficacy of these energy restriction approaches across varied racial/ethnic backgrounds, addressing an urgent need in nutrition and metabolic health research.

Objectives: The Historical Loss Scale (HLS) and Historical Loss Associated Symptoms Scale (HLASS) are standardized measures that have been accepted and previously validated among North American Indigenous communities and allow researchers to measure the impact of Historical Loss. Evidence of the psychometric properties of this instrument have not been assessed for Native Hawaiians, the Indigenous peoples of Hawai'i. The purpose of this study is to investigate the psychometric properties of the adapted HLS (aHLS) and HLASS for adults from multiple Hawaiian Homestead Communities throughout Hawai'i. Methods: Data are based on cross-sectional surveys administered between 2014 and 2020. The final sample included 491 Native Hawaiian adults who were predominantly female (67.3%) and between the ages of 18-90 years, who were part of the larger study entitled the Hawaiian Homestead Health Survey. Factor analyses were conducted to determine the final model structures of each scale. Reliability and correlation matrices of items are also reported. Results: The final factor structure of the aHLS model suggested 3 factors: (1) General loss of culture or cultural loss, (2) Intergenerational loss, and (3) Distrust and destruction of traditional foods. The final HLASS model also suggested 3 factors: (1) Depression and Anger, (2) Shame and Anxiety, and (3) Re-experiencing, fear, and avoidance. Conclusion: These findings have implications for future research, practice, and education that explores the role of Historical Loss and associated symptoms in Native Hawaiians and Indigenous communities at large. In particular, measuring historical loss and associated symptoms in Hawaiian Homestead communities paves the way for quantitative assessments of historical trauma and healing in these communities.

OBJECTIVE: Gastric cancer (GC) disproportionately affects ethnic minorities in the US including Asians and Pacific Islanders. Research with minority groups who are at high risk are needed to provide more effective treatment. Successful recruitment of minorities to research must overcome obstacles of language, access, fear and mistrust. Respondent Driven Sampling (RDS) is a sampling strategy designed to recruit underrepresented minority populations using social networks. However, there are no reports of RDS being used for a case-control study. METHODS: Our pilot study examined the feasibility of using RDS as a recruitment strategy to enroll a large number of participants to develop a GC screener. Our preliminary work showed that 750 cases and 5,250 controls would be needed to fully develop this tool. GC cases, who also served as the seeds, were asked to refer 2 more people to participate as controls in our study. Our pilot goal was to recruit 8 GC cases (as seeds) and 112 controls using three waves of referrals and recruitment. RESULTS: Twenty-seven GC cases were contacted of which 10 refused, 4 expressed interested to participate in the survey but were unwilling to recruit controls. Thirteen cases were recruited but only 5 Complete the survey. Of these 5, 3 cases did not pass on referral coupons and only 2 of the participants gave coupons to 3 potential controls. CONCLUSION: Our study revealed the limitations of using RDS with cancer patients to support recruitment. GC patients' constrained social networks, inadequate incentives or other factors may have contributed to the lack of success with using RDS in this setting.

Skin cancer is the most common form of cancer in the United States, and regular use of broad-spectrum sunscreens can prevent skin cancer. However, a new law in Hawaii that limits sunscreen choices due to the belief that some UV (ultraviolet) filters may damage coral reefs may reduce sunscreen use and increase skin-cancer risk. Because of this, there is a need for measurement tools to help understand consumer behavior and determinants of sunscreen purchase and use. The objectives of this study were (1) to test new questionnaire measures relevant to the Hawaii Sunscreen Ban; and (2) to assess adults' knowledge, attitudes, and habits related to sunscreen in two other coastal states. This survey of adult residents of California and Florida was conducted in the summer of 2019. Newly developed scales addressed beliefs about effects of sunscreens on aquatic/marine environments and awareness of the Hawaii sunscreen ban. Respondents completed the survey twice to evaluate the test-retest reliability. Respondents (n = 162) were mainly female, White, and college-educated. New scales had moderate-to-high internal consistency and high test-retest reliability. Sunscreen use was high, sunburn was common, and knowledge and attitudes about sunscreen were modest. Most respondents did not know the specifics of the Hawaii Sunscreen Ban. In multivariate models, significant predictors of sunscreen use were being older, female, and having higher sunscreen knowledge. Sunscreen beliefs were not significantly associated with sunscreen use or sunburn. The findings support the use of the newly developed survey and suggest that more education about sunscreen and sunscreen ingredients is needed.

(1) Background: Currently there are no cancer clinical trials in Guam, where CHamoru people suffer the highest rates of cancer mortality, and interest to do so is growing. This study investigated the knowledge and attitudes of Guam residents towards cancer clinical trial participation prior to implementation. (2) Methods: A telephone survey was developed, tested, and conducted among Guam resident adults, 18 years of age and older. Survey questions were summarized by descriptive statistics. Logistic regression models were used to investigate the associations between Guam residents' demographics and their clinical trial knowledge and attitudes. Adjusted odds ratios (aOR) and associated 95% confidence intervals (CI) were calculated. (3) Results: One hundred fifty-two people participated in the survey, most of whom were CHamoru (47.0%). Fifty-three percent had heard the term 'clinical trial'; 73.7% would take part in a trial if they had cancer; and 59.9% believed they would receive good quality treatment from a trial offered in Guam. CHamoru were more likely than Whites to associate out-of-pocket expenses with clinical trial participation (aOR = 5.34, 95% CI = 1.68-17.00). Physician ethnicity was important to 30% of non-Whites and significantly associated with those who spoke a language other than English (aOR = 3.40, 95% CI = 1.29-8.95). Most people (65.0%) did not believe clinical trials participants were 'guinea pigs'. (4) Conclusion: Though knowledge about cancer clinical trials is limited, attitudes were primarily positive towards participating in cancer clinical trials offered in Guam. Future delivery of cancer clinical trials will benefit from identifying potential barriers to recruitment and adopting an approach suited to Guam's population.
