Disparities in Colorectal Cancer Incidence among Asian and Pacific Islander Populations in Guam, Hawai'i, and the United States.

Colorectal cancer (CRC) ranks among the three most common cancers in Guam (GU), Hawai'i (HI), and the mainland United States (US). CRC prevalence in these areas is high among Filipinos, and indigenous CHamorus and Native Hawaiians; however, data on these populations are frequently aggregated in epidemiological studies, which can mask true CRC disparities. We examined CRC cumulative incidence rates (CIRs) among CHamorus in GU, Filipinos in GU, HI, and the US, and Native Hawaiians in HI and the US. CRC CIRs were calculated for two age groups (20-49 years; early onset, and 50-79 years; senior) and four time periods (2000-2004, 2005-2009, 2010-2014, and 2015-2019), stratified by ethnicity, sex, and location. Data analyzed included all invasive CRC cases reported to the Surveillance, Epidemiology, and End Results 9-Registry (n = 166,666), the Hawai'i Tumor Registry (n = 10,760), and the Guam Cancer Registry (n = 698) between 2000 and 2019. Senior CIRs were highest in HI and lowest in GU throughout all time periods, with a downward trend observed for senior CIRs in the US and HI, but not GU. This downward trend held true for all ethnic groups, except for CHamorus in GU, females in GU, and females of CHamoru ethnicity in GU. In contrast, early onset CIRs increased across all locations, sexes, and ethnic groups, except for Filipinos in HI and males of Filipino ethnicity in HI. Our findings provide crucial insights for future research and policy development aimed at reducing the burden of CRC among indigenous populations.

[Parkinson-dementia and amyotrophic lateral sclerosis association (complex of Guam). Diagnostic challenge, Mexican patient]. / Asociación Parkinson-demencia y esclerosis lateral amiotrófica (complejo Guam). Reto diagnóstico, paciente mexicano.

Background: The Amyotrophic Lateral Sclerosis-Parkinsonism-Dementia Complex (ALS-PDC) was first described in the islands of Guam. This pathology presented its peak incidence in the 1950s. Due to the rarity of the association, we report a clinical case with this complex. The objective was to describe the nosological and pathogenic implications of these neurodegenerative disorder, since they are not frequent to find in our population. Clinical case: We present a case of Latinoamerican origin who initially manifested systemic symptoms of more than 6 years of evolution, with subsequent cognitive alterations. Later, patient began with gait disturbances and motor symptoms suggestive of parkinsonism with atypical data and data of motor neurone disease (MND). More studies were carried out and confirmed findings compatible with upper and lower motor neuron involvement. A mutation in the POLG gene was observed, related to mitochondrial depletion syndrome. Conclusion: Despite the knowledge of this association, it is an entity whose clinical diagnosis could be very difficult to achieve. In addition, molecular mechanisms have not been fully identified, the most common genes related to Parkinsonism and ALS have been excluded, and even attempts to locate the locus were made, without achieving accurate results. Unfortunately, being a neurodegenerative disease, the prognosis is fatal, with no disease-modifying treatment.

Introducción: el complejo parkinsonismo-demencia-esclerosis lateral amiotrófica fue descrito por primera vez en las islas de Guam. Esta patología presentó su pico de incidencia en los años 50. Debido a la rareza de la asociación, informamos sobre un caso clínico que la presenta. El objetivo fue describir las implicaciones nosológicas y patogénicas de este trastorno neurodegenerativo, ya que no es frecuente encontrar esta asociación en nuestra población. Caso clínico: presentamos un caso de origen latinoamericano que inicialmente se manifestó con síntomas sistémicos de más de 6 años de evolución, con posteriores alteraciones cognitivas. Después presentó alteraciones de la marcha y síntomas motores sugestivos de parkinsonismo con datos atípicos y datos de enfermedad de motoneurona. Se hicieron estudios de extensión que confirmaron hallazgos compatibles con afectación en motoneurona superior e inferior. Observamos mutación en gen POLG, relacionada con síndrome de depleción mitocondrial. Conclusión: a pesar del conocimiento de esta asociación, es una entidad cuyo diagnóstico clínico puede ser muy difícil de obtener. Además, no se han identificado del todo los mecanismos moleculares, se han excluido los genes más comunes relacionados con parkinsonismos y esclerosis lateral amiotrófica e incluso se intentó localizar el locus, sin lograr resultados certeros. Desafortunadamente al ser una enfermedad neurodegenerativa el pronóstico es fatal, sin que haya tratamiento modificador de la enfermedad.

Breast, cervical, and colorectal cancer screening test use in the US territories of Guam, Puerto Rico, and the US Virgin Islands.

BACKGROUND: The United States Preventive Services Task Force (USPSTF) recommends breast, cervical, and colorectal cancer screening among eligible adults, but information on screening use in the US territories is limited. METHODS: To estimate the proportion of adults up-to-date with breast, cervical, and colorectal cancer screening based on USPSTF recommendations, we analyzed Behavioral Risk Factor Surveillance System data from 2016, 2018, and 2020 for the 50 US states and DC (US) and US territories of Guam and Puerto Rico and from 2016 for the US Virgin Islands. Age-standardized weighted proportions for up-to-date cancer screening were examined overall and by select characteristics for each jurisdiction. RESULTS: Overall, 67.2% (95% CI: 60.6-73.3) of women aged 50-74 years in the US Virgin Islands, 74.8% (70.9-78.3) in Guam, 83.4% (81.7-84.9) in Puerto Rico, and 78.3% (77.9-78.6) in the US were up-to-date with breast cancer screening. For cervical cancer screening, 71.1% (67.6-74.3) of women aged 21-65 years in Guam, 81.3% (74.6-86.5) in the US Virgin Islands, 83.0% (81.7-84.3) in Puerto Rico, and 84.5% (84.3-84.8) in the US were up-to-date. For colorectal cancer screening, 45.2% (40.0-50.5) of adults aged 50-75 years in the US Virgin Islands, 47.3% (43.6-51.0) in Guam, 61.2% (59.5-62.8) in Puerto Rico, and 69.0% (68.7-69.3) in the US were up-to-date. Adults without health care coverage reported low test use for all three cancers in all jurisdictions. In most jurisdictions, test use was lower among adults with less than a high school degree and an annual household income of < $25,000. CONCLUSION: Cancer screening test use varied between the US territories, highlighting the importance of understanding and addressing territory-specific barriers. Test use was lower among groups without health care coverage and with lower income and education levels, suggesting the need for targeted evidence-based interventions.

Suicide risk and prevention in Guam: Clinical and research considerations and a call to action.

The suicide rate in Guam, a United States (U.S.) territory, is markedly higher than the suicide rate within the U.S. There are also important differences in who is most at risk for suicide in Guam, relative to within the general U.S. Understanding these distinctions is important for implementing effective suicide prevention initiatives in this region. In the current article, we discuss considerations for preventing suicide in Guam, including distinctions in suicide risk, relative to within the general U.S. For example, suicide rates in Guam are highest for those who are Pacific Islander, young, or male. Further, suicide in Guam more commonly involves hanging and less commonly involves firearms, a pattern that differs from suicide methods used within the general U.S. Additional considerations include the large military and Veteran population in Guam, as well as cultural and religious beliefs regarding suicide. Finally, given the geographic isolation of Guam, access to healthcare is likely an important facet of suicide risk. Considering these characteristics, it is imperative to develop and implement culturally-sensitive suicide prevention interventions for individuals residing in this region. We conclude by discussing future research avenues to address critical knowledge gaps to prevent suicide in Guam.

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.

Alzheimer's Disease and Related Dementia in Indigenous Populations: A Systematic Review of Risk Factors.

BACKGROUND: There remains a lack of information and understanding of the prevalence and incidence of Alzheimer's disease and related dementia in Indigenous populations. Little evidence available suggests that Indigenous peoples may have disproportionately high rates of Alzheimer's disease and related dementia (ADRD). OBJECTIVE: Given this information, this study systematically explores what risk factors may be associated with ADRD in Indigenous populations. METHODS: A search of all published literature was conducted in October 2016, March 2018, and July 2019 using Medline, Embase, and PsychINFO. Subject headings explored were inclusive of all terms related to Indigenous persons, dementia, and risk. All relevant words, phrases, and combinations were used. To be included in this systematic review, articles had to display an association of a risk factor and ADRD. Only studies that reported a quantifiable measure of risk, involved human subjects, and were published in English were included. RESULTS: Of 237 articles originally identified through database searches, 45 were duplicates and 179 did not meet a priori inclusion criteria, resulting in 13 studies eligible for inclusion in this systematic review. CONCLUSION: The large number of potentially modifiable risk factors reported relative to non-modifiable risk factors illustrates the importance of socioeconomic context in the pathogenesis of ADRD in Indigenous populations. The tendency to prioritize genetic over social explanations when encountering disproportionately high disease rates in Indigenous populations can distract from modifiable proximal, intermediate, and distal determinants of health.

Prevalence and Predictors of Overweight and Obesity among Young Children in the Children's Healthy Living Study on Guam.

This study is part of the Children's Healthy Living program in U.S. Affiliated Pacific region. The objectives were to estimate overweight and obesity (OWOB) prevalence and identify possible related risk factors among ethnic groups in Guam. In 2013, 865 children (2-8 years) were recruited via community-based sampling from select communities in Guam. Children's demographic and health behavior information; dietary intake; and anthropometric measurements were collected. Logistic regression, odds ratio, t-tests, and chi-square tests were used to determine differences and assess covariates of OWOB. The results indicate that 58% of children were living below the poverty level, 80% were receiving food assistance, and 51% experienced food insecurity. The majority of children surveyed did not meet recommendations for: sleep duration (59.6%), sedentary screen-time (83.11%), or fruit (58.7%) and vegetable (99.1%) intake, and consumed sugar sweetened beverages (SSB) (73.7%). OWOB affected 27.4% of children. Children affected by OWOB in this study were statistically more likely (p = 0.042) to suffer from sleep disturbances (p = 0.042) and consume marginally higher amounts (p value = 0.07) of SSB compared to children with healthy weight. Among Other Micronesians, children from families who considered themselves 'integrated' into the culture were 2.05 (CI 0.81-5.20) times more likely to be affected by OWOB. In conclusion, the OWOB prevalence among 2-8-year-olds in Guam was 27.4%; and compared with healthy weight children, children with OWOB were more likely to have educated caregivers and consume more SSBs. Results provide a basis for health promotion and obesity prevention guidance for children in Guam.

Smoking, Nutrition, Alcohol, Physical Activity, and Obesity (SNAPO) Health Indicators Among College Students in Guam.

Background/Purpose: The Guam Non-Communicable Disease (NCD) Consortium developed action teams as part of their strategic plan to reduce the risk of NCDs. Smoking, Nutrition, Alcohol, Physical Activity, and Obesity (SNAPO) health indicators were targeted. The primary objective of this study was to describe SNAPO among students at the University of Guam. Methods: A cross-sectional study was conducted from September to December 2015 on a non-random sample of students (n=378; 185 males, 193 females) ≥18 years old attending the University of Guam. Information on SNAPO indicators (smoking/tobacco-related uses, poor nutritional behaviors, alcohol use, physical inactivity, and obesity) were collected using questions from the Guam Behavioral Risk Factor Surveillance System and other local studies. Statistical tests were used to determine sex-specific differences. Results: The overall prevalence of SNAPO health indicators included cigarette smoking (9.1%), smokeless tobacco use (6.7%), areca nut chewing (7.5%), alcohol consumption (44.3%) and binge drinking (24.6%), physical inactivity (54.5%), infrequent fruit (77.5%) and vegetable (68.0%) consumption, frequent fast food consumption (31.5%), inadequate water intake (89.1%) and obesity (22.6%). Sex-specific statistical differences were marginal for cigarette smoking and smokeless tobacco use and significant for physical inactivity and obesity. Conclusion: The SNAPO health indicators provide an updated status of substance use and obesity-related risk factors of college students in Guam. Continued collection of the data is encouraged to inform campus-wide policies or programs that promote student health, monitor student health trends, and evaluate the Guam NCD Strategic Plan over time.

Cumulative Incidence Rates of Breast Cancer by Age for Filipinos and Chamorros in Guam.

Breast cancer is the second leading cause of cancer-related death among women on Guam and Hawai'i. Breast cancer incidence rates are described here for the multiethnic population in Guam, a United States (US) Pacific island territory, and compared to Hawai'i and other US populations, to understand the risk by age and race/ethnic group in this understudied group. The study included all breast cancer cases (n=576) reported to the Guam Cancer Registry, all breast cancer cases (n=8345) reported to the Hawai'i Tumor Registry and all breast cancer cases (n=678,637) reported to the Surveillance, Epidemiology, and End Results program from 2000 to 2009. Cumulative incidence rates by age were calculated for two time periods: 2000-2004 and 2005-2009. Differences were seen in cumulative incidence rates by age, ethnicity, and place of residence. Cumulative incidence rates by age 40 were the highest (0.7%) among Filipinos in Guam but, after age 40, the rates for Chamorros (indigenous Pacific Islanders of Guam) increased rapidly. The lifetime cumulative incidence rates were the highest for Chamorros in Guam (15.3%), close to the US rate (15.5%). Results were similar for 2005-2009. Women in Guam are at high risk for breast cancer, with the indigenous Chamorros having the highest risk, and the most prevalent Asian group of Filipinos, having a younger age at diagnosis. These patterns are similar to the comparable Pacific Islander and Filipino populations in Hawai'i and the US generally.

Using a Short Message System to Increase Cervical Cancer Screening Uptake among Chuukese Women in Guam: Lessons Learned from Linking Distance Technology Between Carriers and Using Telehealth Communication in a Cross-Cultural Context.

This paper reports on a project aimed at using a short message system (SMS) to increase cervical cancer screening uptake among Chuukese women in Guam. It documents the process and identifies the unexpected challenges which led to the early termination of the study. Although the original aims of the project were not met, there were some lessons learned about technology incompatibility in the context of Guam's and the United States' cell phone technology interface, the cultural nuances of cell phone use in the study population, and the necessity to follow a protocol for the termination of a project.

Adolescent Tobacco and Betel Nut Use in the US-Affiliated Pacific Islands: Evidence From Guam.

PURPOSE: To determine the prevalence of, and the risk and protective factors associated with, tobacco product use among adolescents in Guam, a US-Affiliated Pacific Island (USAPI) territory. To examine disparities in risk and protective factors across indigenous and nonindigenous groups. DESIGN: Quantitative; cross-sectional. SETTING: Middle and high schools in Guam. SAMPLE: The Global Youth Tobacco Survey sample included a representative sample of 2449 6th to 12th graders (71% response rate). Sample for the supplemental study included 670 middle school students (76% response rate across randomly selected classrooms). MEASURES: Self-reported measures of lifetime and past 30-day tobacco and betel nut use, social competence, resistance self-efficacy, risk perceptions, friend and family tobacco product use, and ease of access to tobacco products. ANALYSIS: Multilevel logistic regression and analysis of covariance. RESULTS: The prevalence rates of current cigarette, smokeless tobacco, and e-cigarette use among middle school students were 8%, 8%, and 25%, respectively. Ability to resist social pressure to use tobacco/betel nut use was strongly associated with lower likelihood of tobacco (odds ratio [OR] = 0.76; 95% confidence interval [CI]: 0.68-0.84) and betel nut use (OR = 0.74; 95% CI: 0.67-0.82). Indigenous Pacific Islanders scored significantly lower on protective and higher on risk factors. CONCLUSION: Tobacco product use rates among Guam middle school students appear to be 4 to 5 times higher than the US national average rates. There is an urgent need for developing tobacco and betel nut use prevention programs for USAPI youth that are tailored to the needs of indigenous Pacific Islanders.

Rickettsia species in ticks collected from wild pigs (Sus scrofa) and Philippine deer (Rusa marianna) on Guam, Marianna Islands, USA.

The prevalence and diversity of ticks on wildlife species on Guam is understudied, as to date no work has been conducted on the infection of these ticks with Rickettsia (obligate intracellular pathogens that use a variety of ectoparasites as vectors and can cause disease in humans, domestic animals, and wildlife species). The goal of our study was to investigate the presence of Rickettsia species on the island of Guam by testing ticks found on Philippine deer (Rusa marianna) and wild pigs (Sus scrofa). Increasing numbers of these species have led to increased interactions with humans, including hunting, highlighting the importance of studies on vector prevalence and associated zoonotic pathogens. In this study, ticks were removed from Philippine deer and wild pigs in March and April of 2015 and tested for Rickettsia spp. using nested PCR. Overall, a low prevalence of Rickettsia spp. was detected (5.4% (6/112 ticks)). Ticks removed from wild pigs were identified as Amblyomma breviscutatum, one of which was positive for Rickettsia ambylommatis. Ticks recovered from Philippine deer were identified as Rhipicephalus microplus, and five were positive for Rickettsia; two with R. amblyommatis and one with 'Candidatus Rickettsia senegalensis', a recently proposed species in the R. felis cluster. The remaining two sequences were short and species classification was not possible. Rickettsia felis is a known zoonotic pathogen in the spotted fever group of Rickettsia and there is evidence that 'C. R. senegalensis' can also cause illness in people. This study confirms the occurrence of Rickettsia in ticks on Guam and highlights the presence of potential human pathogenic species in the R. felis cluster.

An epidemiologic and clinical description of e-cigarette toxicity.

INTRODUCTION: E-cigarettes are battery-powered electronic nicotine delivery systems that simulate smoking by vaporizing nicotine-containing solutions. Systematic published data on e-liquid toxicity and exposures are limited to case reports and retrospective studies. Prospectively-collected data on the type of exposure, symptomatology, duration of symptoms, and concentration/flavor of e-fluids has not been published. METHODS: This was a prospective observational study over a 42-month period (07/01/2014-12/31/2017). For all calls to a single poison center that involved e-cigarette devices or refill fluid, a data collection instrument was filled out by the specialist in poison information (SPI). RESULTS: Two hundred sixty-five total cases were identified, including 193 children and 72 adults. The majority of both pediatric (72%; 139/193) and adult (61%; n = 44/72) exposures involved e-liquid refill containers or fluid. Fifty-six percent (n = 108/193) of pediatric exposures involved ingestion of refill liquid. Though children who ingested e-liquid received only a small amount, initial symptoms were evident in 32% (n = 35/108) of cases. Children who did not ingest or inhale the products were less likely to develop toxicity. Only 2 children who were asymptomatic on initial call became symptomatic on follow-up. Most patients symptoms resolved within 4 hours. Seventy-one specific products/brands were identified with nicotine concentrations ranging from 0 mg/mL to 60 mg/mL with one product containing 3000 mg in a single bottle. A variety of flavors were identified, including several with names that may be attractive to toddlers or adolescents. DISCUSSION: E-cig exposures tend to produce irritant effects from topical exposures and nicotine toxicity from ingestions, as well as some dermal and "sucking" toddler exposures. CONCLUSION: Exposure to e-cig fluid or device frequently causes mild symptoms and rarely may produce systemic nicotine toxicity.

Prevalence of Five Health-Related Behaviors for Chronic Disease Prevention Among Sexual and Gender Minority Adults - 25 U.S. States and Guam, 2016.

In recent decades, public health awareness of health disparities among lesbian, gay, bisexual, and transgender (LGBT) populations has increased (1). Healthy People 2020 included objectives to improve health of LGBT persons.† Five key health-related behaviors were found to be likely associated with reduced all-cause mortality: never smoking, performing regular physical activity, consuming no or moderate amounts of alcohol, having a normal body weight, and obtaining sufficient sleep daily (2). CDC estimated these five health-related behaviors among adults aged ≥21 years by sexual orientation and transgender status using data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS) in 25 U.S. states and Guam. Patterns of these five health-related behaviors varied by sexual orientation among men and women, and among transgender adults. Lesbian and bisexual women were less likely to engage in all five health-related behaviors than were heterosexual women (5.4% and 6.9%, respectively, versus 10.6%). Compared with cisgender§ adults, male-to-female transgender adults were less likely to engage in any two of five health-related behaviors (12.3% versus 18.6%). Male-to-female transgender adults, however, were more likely to engage in any three of five health-related behaviors than were female-to-male transgender adults (47.2% versus 28.2%). The number of health-related behaviors did not differ between gay or bisexual men and heterosexual men. Continued efforts are needed to target LGBT populations for overall well-being, including strategies for health promotion and engagement in health-related behaviors.

Surveillance for Certain Health Behaviors and Conditions Among States and Selected Local Areas - Behavioral Risk Factor Surveillance System, United States, 2015.

PROBLEM: Chronic conditions and disorders (e.g., diabetes, cardiovascular diseases, arthritis, and depression) are leading causes of morbidity and mortality in the United States. Healthy behaviors (e.g., physical activity, avoiding cigarette use, and refraining from binge drinking) and preventive practices (e.g., visiting a doctor for a routine check-up, tracking blood pressure, and monitoring blood cholesterol) might help prevent or successfully manage these chronic conditions. Monitoring chronic diseases, health-risk behaviors, and access to and use of health care are fundamental to the development of effective public health programs and policies at the state and local levels. REPORTING PERIOD: January-December 2015. DESCRIPTION OF THE SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit-dialed landline- and cellular-telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health-risk behaviors, chronic diseases and conditions, access to and use of health care, and use of preventive health services related to the leading causes of death and disability. This report presents results for all 50 states, the District of Columbia, the Commonwealth of Puerto Rico (Puerto Rico), and Guam and for 130 metropolitan and micropolitan statistical areas (MMSAs) (N = 441,456 respondents) for 2015. RESULTS: The age-adjusted prevalence estimates of health-risk behaviors, self-reported chronic health conditions, access to and use of health care, and use of preventive health services varied substantially by state, territory, and MMSA in 2015. Results are summarized for selected BRFSS measures. Each set of proportions refers to the median (range) of age-adjusted prevalence estimates for health-risk behaviors, self-reported chronic diseases or conditions, or use of preventive health care services by geographic jurisdiction, as reported by survey respondents. Adults with good or better health: 84.6% (65.9%-88.8%) for states and territories and 85.2% (66.9%-91.3%) for MMSAs. Adults with ≥14 days of poor physical health in the past 30 days: 10.9% (8.2%-17.2%) for states and territories and 10.9% (6.6%-19.1%) for MMSAs. Adults with ≥14 days of poor mental health in the past 30 days: 11.3% (7.3%-15.8%) for states and territories and 11.4% (5.6%-20.5%) for MMSAs. Adults aged 18-64 years with health care coverage: 86.8% (72.0%-93.8%) for states and territories and 86.8% (63.2%-95.7%) for MMSAs. Adults who received a routine physical checkup during the preceding 12 months: 69.0% (58.1%-79.8%) for states and territories and 69.4% (57.1%-81.1%) for MMSAs. Adults who ever had their blood cholesterol checked: 79.1% (73.3%-86.7%) for states and territories and 79.5% (65.1%-87.3%) for MMSAs. Current cigarette smoking among adults: 17.7% (9.0%-27.2%) for states and territories and 17.3% (4.5%-29.5%) for MMSAs. Binge drinking among adults during the preceding 30 days: 17.2% (11.2%-26.0%) for states and territories and 17.4% (5.5%-24.5%) for MMSAs. Adults who reported no leisure-time physical activity during the preceding month: 25.5% (17.6%-47.1%) for states and territories and 24.5% (16.1%-47.3%) for MMSAs. Adults who reported consuming fruit less than once per day during the preceding month: 40.5% (33.3%-55.5%) for states and territories and 40.3% (30.1%-57.3%) for MMSAs. Adults who reported consuming vegetables less than once per day during the preceding month: 22.4% (16.6%-31.3%) for states and territories and 22.3% (13.6%-32.0%) for MMSAs. Adults who have obesity: 29.5% (19.9%-36.0%) for states and territories and 28.5% (17.8%-41.6%) for MMSAs. Adults aged ≥45 years with diagnosed diabetes: 15.9% (11.2%-26.8%) for states and territories and 15.7% (10.5%-27.6%) for MMSAs. Adults aged ≥18 years with a form of arthritis: 22.7% (17.2%-33.6%) for states and territories and 23.2% (12.3%-33.9%) for MMSAs. Adults having had a depressive disorder: 19.0% (9.6%-27.0%) for states and territories and 19.2% (9.9%-27.2%) for MMSAs. Adults with high blood pressure: 29.1% (24.2%-39.9%) for states and territories and 29.0% (19.7%-41.0%) for MMSAs. Adults with high blood cholesterol: 31.8% (27.1%-37.3%) for states and territories and 31.4% (23.2%-42.0%) for MMSAs. Adults aged ≥45 years who have had coronary heart disease: 10.3% (7.2%-16.8%) for states and territories and 10.1% (4.7%-17.8%) for MMSAs. Adults aged ≥45 years who have had a stroke: 4.9% (2.5%-7.5%) for states and territories and 4.7% (2.1%-8.4%) for MMSAs. INTERPRETATION: The prevalence of health care access and use, health-risk behaviors, and chronic health conditions varied by state, territory, and MMSA. The data in this report underline the importance of continuing to monitor chronic diseases, health-risk behaviors, and access to and use of health care in order to assist in the planning and evaluation of public health programs and policies at the state, territory, and MMSA level. PUBLIC HEALTH ACTION: State and local health departments and agencies and others interested in health and health care can continue to use BRFSS data to identify groups with or at high risk for chronic conditions, unhealthy behaviors, and limited health care access and use. BRFSS data also can be used to help design, implement, monitor, and evaluate health-related programs and policies.

Are the U.S. territories lagging behind in diabetes care practices?

AIMS: Although U.S. territories fall within the mandate outlined by Healthy People 2020, they remain neglected in diabetes care research. We compared the prevalence and secular trends of four recommended diabetes care practices in the U.S. territories of Guam, Puerto Rico, and the U.S. Virgin Islands to the 50 United States and D.C. ("U.S. States") in 2001-2015. METHODS: Data were from 390,268 adult participants with self-reported physician diagnosed diabetes in the Behavioral Risk Factor Surveillance System. Diabetes care practices included biannual HbA1c tests, attendance of diabetes education classes, daily self-monitoring of blood glucose, and receipt of annual foot examination. Practices were compared by U.S. territory and between territories and U.S. states. Multivariable models accounted for age, sex, education, and year. RESULTS: Of adults with diagnosed diabetes, 7% to 11% in the U.S. territories engaged in all four recommended diabetes care practices compared with 25% for those, on average, in U.S. states. Relative to the U.S. states, on average, the proportion achieving biannual HbA1c testing was lower in Guam and the U.S. Virgin Islands (45.6% and 44.9% vs. 62.2%), while annual foot examinations were lower in Puerto Rico (45.9% vs 66.1% in the U.S. states). Diabetes education and daily glucose self-monitoring were lower in all three territories. CONCLUSIONS: U.S. territories lag behind U.S. states in diabetes care practices. Policies aimed at improving diabetes care practices are needed in the U.S. territories to achieve Healthy People 2020 goals and attain parity with U.S. states.

Effect of the Children's Healthy Living Program on Young Child Overweight, Obesity, and Acanthosis Nigricans in the US-Affiliated Pacific Region: A Randomized Clinical Trial.

Importance: Pacific Islanders have among the highest rates of obesity and type 2 diabetes in the world. Targeting children is critical for primary prevention. Objectives: To prevent young child overweight and obesity and to improve health in the US-Affiliated Pacific region via the Children's Healthy Living Program. Design, Setting, and Participants: In this multijurisdictional, multilevel, multicomponent community randomized clinical trial, where all evaluable children were analyzed according to the random assignment of their community, hierarchical difference-in-difference models accounted for the community randomization, community clustering with jurisdictions, and these models were adjusted for the age and sex distribution of the community. The setting was 27 communities in 5 jurisdictions (Alaska, American Samoa, Commonwealth of the Northern Mariana Islands, Guam, and Hawaii). Participants were 4329 children (time 1) and 4042 children (time 2) aged 2 to 8 years in 27 selected communities from October 7, 2012, to October 25, 2015. Data analysis was completed in June 2018. Interventions: Nineteen activities addressed policy, environment, messaging, training, and 6 target behaviors (sleep time, screen time, physical activity, fruits and vegetables, water, and sugar-sweetened beverages). Main Outcomes and Measures: Primary outcomes were body size measurements. Secondary outcomes were acanthosis nigricans, sleep quality and duration, dietary intake, physical activity, and other questionnaire reponses. Results: The study included 27 communities and 8371 evaluable children (mean [SD] age, 5.4 [1.8] years; 50.9% male [n = 4264]). Data analysis included 952 children in the intervention group and 930 children in the control group aged 2 to 5 years at time 1; 825 children in the intervention group and 735 children in the control group aged 2 to 5 years at time 2; 565 children in the intervention group and 561 children in the control group aged 6 to 8 years at time 1; and 517 children in the intervention group and 560 children in the control group aged 6 to 8 years at time 2. The intervention communities showed significant improvement compared with control communities in overweight and obesity prevalence (effect size [d] = -3.95%; 95% CI, -7.47% to -0.43%), waist circumference (d = -0.71 cm; 95% CI, -1.37 to -0.05 cm), and acanthosis nigricans prevalence (d = -2.28%; 95% CI, -2.77% to -1.57%). Age and sex subgroup analysis revealed greater difference among the intervention communities in acanthosis nigricans prevalence in the group aged 2 to 5 years (-3.99%) vs the group aged 6 to 8 years (-3.40%), and the interaction was significant (d = 0.59%, P < .001), as well as the smaller difference in the group aged 2 to 5 years (-0.10%) vs the group aged 6 to 8 years (-1.07%) in screen time (d = -0.97 hour per day, P = .01). Conclusions and Relevance: The intervention reduced the prevalence of young child overweight and obesity and acanthosis nigricans. Comprehensive, effective, and sustainable interventions are needed to improve child health in the US-Affiliated Pacific region. Trial Registration: ClinicalTrials.gov Identifier: NCT01881373.

Prenatal Screening for and Prevalence of Hepatitis B Surface Antigen in Pregnant Women and Prevention of Transmission to Infants Born to Infected Mothers-Guam, 2014.

BACKGROUND: Perinatal transmission is the major mode of hepatitis B virus (HBV) transmission and drives HBV endemicity in the US territory of Guam. We assessed correlates of prenatal hepatitis B surface antigen (HBsAg) screening and HBsAg positivity among pregnant women and evaluated the care of infants of HBsAg-positive women. METHODS: Demographic and clinical data were abstracted from the maternal medical records of 966 randomly selected live infants born in 2014. Frequencies were calculated, and prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using Poisson regression. RESULTS: Among the mothers of the 966 infants, 78.2% were Pacific Islanders, 56.9% were >25 years old (born before universal infant hepatitis B vaccination in Guam), 89.0% received prenatal care (PNC), 96.7% underwent prenatal HBsAg screening, and 2.0% were HBsAg positive. Approximately 15% of the women who did not have PNC were not screened for HBsAg. Receipt of PNC was associated with HBsAg screening (adjusted PR, 1.13 [95% CI, 1.04-1.23]), and HBsAg positivity was associated with a maternal age of >25 years (adjusted PR, 6.80 [95% CI, 1.32-35.08]). All 18 infants of the HBsAg-positive mothers received hepatitis B vaccine, and 17 (94.4%) received hepatitis B immunoglobulin. CONCLUSION: Although the prenatal HBsAg screening prevalence in this sample was high, the maternal HBsAg prevalence among women in this sample was more than 14 times and 2 times the prevalence among US-born Pacific Islander/Asian women and all women in the continental United States, respectively. Improving access to PNC, ensuring that all pregnant women in Guam (especially those born before universal hepatitis B vaccination) are screened for HBsAg, and adopting postexposure prophylaxis for infants of HBsAg-positive mothers as standard clinical practice are important for preventing perinatal HBV transmission and reducing HBV endemicity.

Survey for selected pathogens in Philippine deer (Rusa marianna) from Guam, Marianna Islands, USA.

Philippine deer (Rusa marianna), native to the Philippine Islands, were introduced to Guam in the late 1700's. Dense populations have become established throughout the island where they cause damage to native plant communities resulting in habitat degradation. In addition, cervids can serve as reservoirs for important pathogens of livestock and people. From February-March 2015, blood, tissue and ectoparasite samples were collected from 132 free-ranging Philippine deer on Guam. Data from 10 deer sampled in 1997 were also analyzed. Deer were negative for antibodies to many of the pathogens assessed including epizootic hemorrhagic disease virus, parainfluenza 3 virus, bovine viral diarrhea virus, bovine herpesvirus 1, and Brucella spp.; however, two (2%) and nine (7%) deer were seropositive for bluetongue virus and Toxoplasma gondii, respectively. Five (4%) deer had low titers (1:100) to Leptospira interrogans serovars Bratislava (n=4), Canicola (n=2), and Icterohaemorrhagiae (n=1). None of the kidney samples from Leptospira-seropositive deer were immunohistochemically positive for leptospires. No nematodes or trematodes were detected in lungs, abdomen, abomasum or liver. A few deer had 1-4 Cooperia spp. in the small intestine, although very small nematodes may have not been captured by the #100 mesh used for screening. Of the 105 deer evaluated for ectoparasites, 90.5% were infested with Rhipicephalus microplus. Tick burdens were generally high and classified as low (<500 ticks) (59% of infested deer), medium (500-1000 ticks) (22%), and high (>1000 ticks) (19%). Molecular testing of blood samples for Babesia spp. was negative, but 11 (8%) deer were positive for Anaplasma spp. Sequence analysis revealed that deer were infected with three species of Anaplasma including A. marginale, A. phagocytophilum, and an Anaplasma sp. similar to A. platys. Finding A. marginale, T. gondii, Leptospira and heavy burdens of ticks in Philippine deer is of economic and public health importance.

Cancer in Guam and Hawaii: A comparison of two U.S. Island populations.

BACKGROUND: Cancer disparities within and across populations provide insight into the influence of lifestyle, environment, and genetic factors on cancer risk. METHODS: Guam cancer incidence and mortality were compared to that of Hawaii using data from their respective population-based, central cancer registries. RESULTS: In 2009-2013, overall cancer incidence was substantially lower in Guam than in Hawaii for both sexes while overall cancer mortality was higher for Guam males. Cervical cancer incidence and prostate cancer mortality were higher in Guam. Both incidence and mortality were higher among Guam men for cancers of the lung & bronchus, liver & intrahepatic bile duct, and nasopharynx; Chamorro men were disproportionately affected by these cancers. Filipinos and Whites in Guam had lower overall cancer incidence compared to Filipinos and Whites in Hawaii. Although breast cancer incidence was significantly lower in Guam compared to Hawaii, women in Guam presented at younger ages and with rarer disease histologies such as inflammatory carcinoma were more prevalent. Guam patients were also diagnosed at younger ages for cancers of bladder, pancreas, colon & rectum, liver & intrahepatic bile duct, lung & bronchus, stomach, non-Hodgkin lymphoma, and leukemia. CONCLUSION: Smoking, infectious agents, and betel nut chewing appear to be important contributors to the burden of cancer in Guam. Earlier onset of cancer in Guam suggests earlier age of exposure to key risk factors and/or a more aggressive pathogenesis. Contrasting cancer patterns within Guam and between Guam and Hawaii underscore the potential influence of genes, lifestyle, and environmental factors on cancer development and progression.
