Utilizing Filipino key informants to guide community outreach for cancer prevention in Hawai'i.

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.

Sugar and Aldehyde Content in Flavored Electronic Cigarette Liquids.

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.

Warning Statements and Safety Practices Among Manufacturers and Distributors of Electronic Cigarette Liquids in the United States.

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.

Biomarkers of tobacco smoke exposure in racial/ethnic groups at high risk for lung cancer.

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.

Samoan body and soul: adapting an evidence-based obesity and cancer prevention program.

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.

Knowledge and Attitudes of Guam Residents towards Cancer Clinical Trial Participation.

(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.

Utility of self-rated adherence for monitoring dietary and physical activity compliance and assessment of participant feedback of the Healthy Diet and Lifestyle Study pilot.

BACKGROUND: We examined the utility of self-rated adherence to dietary and physical activity (PA) prescriptions as a method to monitor intervention compliance and facilitate goal setting during the Healthy Diet and Lifestyle Study (HDLS). In addition, we assessed participants' feedback of HDLS. HDLS is a randomized pilot intervention that compared the effect of intermittent energy restriction combined with a Mediterranean diet (IER + MED) to a Dietary Approaches to Stop Hypertension (DASH) diet, with matching PA regimens, for reducing visceral adipose tissue area (VAT). METHODS: Analyses included the 59 (98%) participants who completed at least 1 week of HDLS. Dietary and PA adherence scores were collected 8 times across 12 weeks, using a 0-10 scale (0 = not at all, 4 = somewhat, and 10 = following the plan very well). Adherence scores for each participant were averaged and assigned to high and low adherence categories using the group median (7.3 for diet, 7.1 for PA). Mean changes in VAT and weight from baseline to 12 weeks are reported by adherence level, overall and by randomization arm. Participants' feedback at completion and 6 months post-intervention were examined. RESULTS: Mean ± SE, dietary adherence was 6.0 ± 0.2 and 8.2 ± 0.1, for the low and high adherence groups, respectively. For PA adherence, mean scores were 5.9 ± 0.2 and 8.5 ± 0.2, respectively. Compared to participants with low dietary adherence, those with high adherence lost significantly more VAT (22.9 ± 3.7 cm2 vs. 11.7 ± 3.9 cm2 [95% CI, - 22.1 to - 0.3]) and weight at week 12 (5.4 ± 0.8 kg vs. 3.5 ± 0.6 kg [95% CI, - 3.8 to - 0.0]). For PA, compared to participants with low adherence, those with high adherence lost significantly more VAT (22.3 ± 3.7 cm2 vs. 11.6 ± 3.6 cm2 [95% CI, - 20.7 to - 0.8]). Participants' qualitative feedback of HDLS was positive and the most common response, on how to improve the study, was to provide cooking classes. CONCLUSIONS: Results support the use of self-rated adherence as an effective method to monitor dietary and PA compliance and facilitate participant goal setting. Study strategies were found to be effective with promoting compliance to intervention prescriptions. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03639350 .

Using the Social-Ecological Model as a research and intervention framework to understand and mitigate obesogenic factors in Samoan populations.

OBJECTIVE: The purpose of this study is to identify the relevant contributions and interactions of political, socioeconomic, cultural, and biological factors toward the increasing rates of obesity in Samoans. The constructs of the Social-Ecological Model of Health, which posit that there are multiple levels of influence on individual health behaviors, are used as a conceptual framework to synthesize the current research investigating obesity and chronic diseases in Samoan populations. DESIGN: Twenty-five studies, representing over 20 years of empirical research with Samoans, were assessed and synthesized. These studies included quantitative and qualitative designs. The reviewed studies used participants from (Western) Samoa and American Samoa jurisdictions, as well as migrant Samoan populations living in the USA and New Zealand. RESULTS: Analysis of the current research revealed a convergence of factors, including the effects of recent political and socioeconomic changes in Samoan jurisdictions, combined with specific Samoan cultural and biological dynamics, which have contributed to the current trends toward poor health in Samoans. Interventions designed to address obesity in Samoans must be able to modify multiple determinants of personal health, with particular emphasis on the appropriate use of Samoan cultural concepts. CONCLUSIONS: The application of the Social-Ecological Model of Health, as used in this review, provides guidance for future investigations that may identify multiple factors that contribute to disparities in health. The use of intervention strategies, designed to improve the health status of Samoans, may also indicate methods to address obesity and the development of chronic diseases in other population groups who share similar social conditions and health trends.

"Sun Safe Kids," implementing a low cost, school-based public policy to protect Hawaii's children from skin cancer risks.

The rates of melanomas and skin cancers are increasing in the United States. Children attending elementary schools are in the most danger of acquiring these diseases later in life, and elementary school children in Hawaii have the greatest risk of all children in the United States. The parents and educators of Hawaii's elementary school age children are unaware of the potential risks for cancer that young children experience every day at school. Effective sun protection policies have been implemented in other jurisdictions, including Australia, that have similar risks for over-exposure to solar ultraviolet radiation in children. These proven policy models can inform sun protection practices in Hawaii. A simple policy whereby public elementary schools require that children wear ordinary long sleeves shirts and hats during the school's outdoor activities will protect Hawaii's children from overexposure to sun's ultraviolet radiation. Establishment of a state law codifying the implementation of this simple, yet scientifically proven strategy into the policies of Hawaii's public elementary schools can significantly reduce the incidence and deaths from melanoma and skin cancer in the state.

Preview of Hawaii Cancer Facts and Figures 2010.

Each year, nearly 6,700 Hawaii residents are diagnosed with cancer and more than 2,000 die from the disease. Detailed data on the burden of cancer in Hawaii, including cancer incidence and mortality rates, are available in Hawaii Cancer Facts & Figures 2010 (CF&F). A collaborative effort of the Cancer Research Center of Hawaii, the American Cancer Society and the Hawaii Department of Health, this update of the original version published in 2003 is intended as a tool for public health education, research, and planning. The following are highlights of years 2000-2006 (a 6-year period) data as featured in Hawaii Cancer Facts & Figures 2010.

No Ke Ola Pono o Na Kane: A Culturally Grounded Approach to Promote Health Improvement in Native Hawaiian Men.

In Hawai'i, Native Hawaiian men (kane) have the highest death rate from colon cancer among all ethnic groups. While screening can prevent 90% of these cancers, data show that >58% of kane over age 50 have never been screened. Prior research has demonstrated that community-based social networks may help kane adopt healthy behaviors such as cancer screening, however, few studies have activated such an approach. A cross-sectional study entitled No Ke Ola Pono o Na Kane (for the good health of men) was conducted statewide in Hawai'i from 2014 to 2018. The study strived to perpetuate the Native Hawaiian traditional practice of "hale mua" (men's house) to promote healthy behaviors among kane including the adoption of colon cancer prevention strategies such as fecal immunochemical testing (FIT). The study applied a peer-led intervention model using kane volunteers to deliver the program's educational components, including standardized materials to help the volunteers confidently conduct the sessions. Of the 378 kane who were recruited into the study, 232 participated in the colorectal session of which 64% (n = 149) were over age 50. Survey data from the 149 kane indicated that 31% had not discussed colon health or screening with their doctors but 92% had improved their knowledge about colon health from the session. In addition, 76% (n = 113) agreed to complete a FIT. Session evaluations indicated that >91% of kane liked the hale mua approach and benefited from talking with other kane about their health.

Effects of Intermittent Energy Restriction Combined with a Mediterranean Diet on Reducing Visceral Adiposity: A Randomized Active Comparator Pilot Study.

Intermittent energy restriction combined with a Mediterranean diet (IER+MED) has shown promise to reduce body fat and insulin resistance. In the Multiethnic Cohort Adiposity Phenotype Study, Japanese Americans had the highest visceral adipose tissue (VAT) when adjusting for total adiposity. We conducted this pilot study to demonstrate feasibility and explore efficacy of following IER+MED for 12 weeks to reduce VAT among East Asians in Hawaii. Sixty volunteers (aged 35-55, BMI 25-40 kg/m2, VAT ≥ 90 cm2 for men and ≥ 80 cm2 for women) were randomized to IER+MED (two consecutive days with 70% energy restriction and 5 days euenergetic MED) or an active comparator (euenergetic Dietary Approaches to Stop Hypertension (DASH) diet). Participants and clinic staff (except dietitians) were blinded to group assignments. IER+MED had significantly larger reductions in DXA-measured VAT and total fat mass (-22.6 ± 3.6 cm2 and -3.3 ± 0.4 kg, respectively) vs. DASH (-10.7 ± 3.5 cm2 and -1.6 ± 0.4 kg) (p = 0.02 and p = 0.005). However, after adjusting for total fat mass, change in VAT was not statistically different between groups; whereas, improvement in alanine transaminase remained significantly greater for IER+MED vs. DASH (-16.2 ± 3.8 U/L vs. -4.0 ± 3.6 U/L, respectively, p = 0.02). Attrition rate was 10%, and participants adhered well to study prescriptions with no reported major adverse effect. Results demonstrate IER+MED is acceptable, lowers visceral and total adiposity among East Asian Americans, and may improve liver function more effectively than a healthful diet pattern.

Adapting a Skin Cancer Prevention Intervention for Multiethnic Adolescents.

OBJECTIVE: We tested the effectiveness of a school-based skin cancer prevention intervention entitled "SunSafe in the Middle School Years" adapted for multiethnic high school students. METHODS: In Hawai'i, 208 10th graders (51.6% Asian, 30.4% Native Hawaiian/Pacific Islander, 8.4% white, 3.5% Hispanic, 2.7% black) participated. Changes in sun protection knowledge, attitudes, and self-reported behaviors were measured using a standardized 18-item survey. The Systematic Observation of Sun Protection Factors (SOSPF) instrument assessed aggregate sun protection behaviors. RESULTS: At posttest, improvements were found in 13 of 18 survey items (p < .05), and retained in 10 items at 12-months following baseline assessments; sun-protection attitudes and intended tanning behavior did not show improvement. Six observers using SOSPF reliably measured students' sun protection behaviors at school including use of hats, sunglasses, long sleeves, lower body coverage, and shade (ICC > .77). CONCLUSIONS: We uncovered a lack of knowledge about UVR exposure, tanning, and lifetime skin cancer risk among multiethnic high school students. We found that students' tanning attitudes may be influenced by self-perceptions regarding their own complexion, but were willing to modify their sun protection behaviors once informed about skin cancer risk.
