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.

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.

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 cm²vs. 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 cm²vs. 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.

Background: To communicate research to the public, the National Cancer Institute developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance, includ­ing the Behavioral Risk Factor Surveillance System, HINTS data are not sufficient to ad­dress unique demographic subpopulations such as US Pacific Islanders (PIs). National sampling methods do not adequately reach participants from small, medically under­served populations.Aim: This study aims to document the cancer-relevant knowledge, attitudes, be­haviors, and information-seeking practices of PIs in Hawaii (HI).Methods: We conducted a cross-sectional survey during 2017-2018 of Native Hawai­ians, Chuukese, and Marshallese in HI using Respondent Driven Sampling (RDS) to recruit these geographically diffuse groups. The modified HINTS survey included ques­tions about cancer knowledge, attitudes and behaviors, health communications, and cultural practices.Results: A total of 515 Native Hawai­ians, 305 Chuukese, and 180 Marshallese completed the survey. Differences were found across a variety of cancer-related attitudes, knowledge, and behaviors. These groups also differed regarding acculturation, health locus of control, and trust in medical professionals. Native Hawaiians were sig­nificantly more acculturated (P=.0001) than Chuukese or Marshallese and more likely to smoke cigarettes (P=.0001). Among participants aged >50 years, we found no significant differences across ethnic groups (P=.30) for those completing a colon cancer screening (37%). However, only 27% were referred to screening by a physician.Conclusions: Cancer prevention programs are greatly needed for PIs in HI. This study provides knowledge concerning the efficiency of RDS to recruit participants, and the role of culture in communications influencing cancer risk behaviors, which may be generalizable to migrant PIs in the United States.

In Hawai’i, Native Hawaiian men (kāne) 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 kāne over age 50 have never been screened. Prior research has demonstrated that community-based social networks may help kāne 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 Nā Kāne (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 kāne including the adoption of colon cancer prevention strategies such as fecal immunochemical testing (FIT). The study applied a peer-led intervention model using kāne volunteers to deliver the program’s educational components, including standardized materials to help the volunteers confidently conduct the sessions. Of the 378 kāne 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 kāne 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 kāne liked the hale mua approach and benefited from talking with other kāne about their health.

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.
