Factors associated with suboptimal colorectal cancer screening in US immigrants

International Region of Birth and Long-Term Outcomes for Patients Undergoing Colorectal Cancer Resection in an Australian Population

BACKGROUND

Overseas birth is associated with a survival advantage in colorectal cancer in Australia. We wished to analyse this survival based on global region of birth, controlling for cancer-specific and other causes of death.

METHODS

A database of resected colorectal cancers from 2010 to 2016 (n = 1596) was grouped according to patient global region of birth. Chi-squared testing was used to compare factors including patient demographics and AJCC stage. Kaplan-Meier and competing-risk analysis were used to compare 5-year survival outcomes between patients born in different regions, and regression analysis was used to control for age.

RESULTS

751 (47.1%) patients were born overseas. 385 (24.1%) originated from Europe, 124 (7.8%) from East and SE Asia, 92 (5.8%) from the Middle East, and the remainder from other global regions. Immigrants from East or SE Asia were more likely to present with node-positive disease (p = 0.048) than those born in Australia. Immigrants from East and SE Asia and the Middle East had significantly better all-cause 5-year survival than patients born in Australia (73.4% and 80.4% vs. 60.4%, p < 0.0001). Immigrants from the Middle East retained their cancer-specific survival advantage after competing risk analysis (HR 0.76, p = 0.027). Immigrants from Europe displayed no significant difference in all-cause or disease-specific survival compared to individuals born in Australia.

CONCLUSION

Patients born in the Middle East appear to have a colorectal cancer-specific survival advantage compared to those born in Australia, unrelated to stage at presentation. This has significant implications for prognosis and future research directions.

Social media use and the relationship with colorectal cancer screening among foreign-born populations in the United States

BACKGROUND

Social media (SM) has emerged as a tool for health-related usage among US adults, including cancer screening promotion. Here, we aimed to assess the differences in health-related SM use between US and foreign-born adults and the relationship between health-related SM use and colorectal (CRC) screening practices.

METHODS

Using data from the fifth edition of the National Cancer Institute's Health Information National Trends Survey (HINTS 5), cycle 2, we compared the differences in health-related SM use between US and foreign-born adults and the effects of SM use on CRC screening by country of birth. We included adults aged 50-75 and excluded participants with a history of CRC. The primary endpoint was CRC screening, which was determined by self-reported CRC screening using colonoscopy, sigmoidoscopy, or stool occult blood testing.

RESULTS

Our study included 1,812 adults, of whom 236 (13.0%) were foreign-born. Most participants (72.1%) reported undergoing CRC screening. Interestingly, we found no discernible difference in health-related SM use [odds ratio [OR] 0.91; 95% CI (0.49, 1.69)] between US and foreign-born adults. Furthermore, our analysis revealed that SM use did not influence CRC screening practices among either group (US-born: 0.88 [95% CI: 0.50, 1.52], foreign-born 0.52 [0.10, 2.51]).

CONCLUSION

Contrary to previous studies, which showed a positive relationship between SM use and satisfactory health-related practices, we found that although foreign-born adults use SM as much as US-born adults, there was no significant relationship between SM use and CRC screening.

Disparities in Cancer Screening Among the Foreign-Born Population in the United States: A Narrative Review

Background: The foreign-born population in the United States has reached a record high over the last three years. Significant disparities in cancer screening rates exist among this population, resulting in later-stage diagnoses and worse outcomes. This narrative review explores the sociodemographic factors, barriers, and interventions influencing cancer screening rates among foreign-born individuals in the U.S. Methods: A comprehensive review of studies was conducted to assess colorectal, cervical, and breast cancer screening disparities among immigrants. Factors examined include length of residence, race and ethnicity, income, education, citizenship, insurance, usual source of care, language, medical literacy, and cultural barriers. Furthermore, the effectiveness of educational interventions, patient navigators, and at-home testing in addressing these screening disparities was evaluated. Results: Immigrants have lower screening rates for colorectal, cervical, and breast cancer compared to U.S.-born individuals, with the largest disparities observed in colorectal cancer. Factors influencing these gaps include shorter duration of residence, Asian ethnicity, and lower income and education levels. Lack of health insurance and of a usual source of care are currently the most significant barriers to screening. Interventions such as education, patient navigation, and at-home testing have shown moderate success in improving screening rates, though data on their effectiveness remain limited. Conclusions: Addressing cancer screening disparities within the U.S. foreign-born population is essential, especially as the immigrant population continues to reach record numbers. Targeted interventions are needed to improve screening among immigrant groups with the lowest completion rates. Future research on these interventions should prioritize larger sample sizes, longitudinal studies, and the utility of new technologies such as artificial intelligence.

Disparities in Cancer Stage of Diagnosis by Rurality in California, 2015 to 2019

BACKGROUND

Cancer rates in rural areas vary by insurance status, socioeconomic status, region, race, and ethnicity.

METHODS

California Cancer Registry data (2015-2019) were used to investigate the stage of diagnosis by levels of rurality for the five most common cancers. The percentage of residents in rural blocks within census tract aggregation zones was categorized into deciles up to 50%. Multivariable logistic regression was used to estimate associations with rurality, with separate models by cancer site, sex, race, and ethnicity (non-Hispanic White and Hispanic). Covariates included individual-level and zone-level factors.

RESULTS

The percentage of late-stage cancer diagnosis was 28% for female breast, 27% for male prostate, 77% for male lung, 71% for female lung, 60% for male colorectal, 59% for female colorectal, 7.8% for male melanoma, and 5.9% for female melanoma. Increasing rurality was significantly associated with increased odds of late-stage cancer diagnosis for female breast cancer (Ptrend < 0.001), male lung cancer (Ptrend < 0.001), female lung cancer (Ptrend < 0.001), and male melanoma (Ptrend = 0.01), after adjusting for individual-level and zone-level factors. The strength of associations varied by sex and ethnicity. For males with lung cancer, odds of late-stage diagnosis in areas with >50% rural population was 1.24 (95% confidence interval, 1.06-1.45) for non-Hispanic White patients and 2.14 (95% confidence interval, 0.86-5.31) for Hispanic patients, compared with areas with 0% rural residents.

CONCLUSIONS

Increasing rurality was associated with increased odds for late-stage diagnosis for breast cancer, lung cancer, and melanoma, with the strength of associations varying across sex and ethnicity.

IMPACT

Our findings will inform cancer outreach to these rural subpopulations.

Nativity Disparities in Colorectal Cancer Screening Among Hispanics in the United States

Hispanics in the United States (U.S.) have previously exhibited lower guideline-concordant colorectal cancer (CRC) screening uptake than non-Hispanic (NH) Whites, with disparities accentuated in foreign-born Hispanics, however it is unclear whether nativity-related CRC screening disparities have changed in the last two decades and whether these disparities are attenuated after adjusting for socioeconomic and demographic characteristics. We evaluated CRC screening adherence in foreign- and U.S.-born Hispanics compared to U.S.-born NH Whites. We used 2019 National Health Interview Survey data to compare the prevalence of up-to-date CRC screening per the 2019 U.S. Preventive Services Task Force recommendations among Hispanic nativity subgroups (i.e., foreign- and U.S.-born) and U.S.-born NH Whites using unadjusted and adjusted weighted log-linked binomial regression. Foreign- and U.S.-born Hispanics had a significantly lower unadjusted prevalence of up-to-date screening than U.S.-born NH Whites (47.18% and 64.18% versus 70.70%; p < 0.0001 and p = 0.0109, respectively). After adjusting for socioeconomic and demographic differences, the prevalence of up-to-date screening was lower in foreign-born Hispanics compared to U.S.-born NH Whites [adjusted prevalence ratio 0.80 (95% confidence interval 0.70-0.91)]; however, no statistically significant difference was observed between U.S.-born Hispanics and NH Whites. Our results suggest a low screening uptake in foreign-born Hispanics independent of socioeconomic and demographic differences. Future interventions should target foreign-born Hispanics to address disparities and promote early detection and prevention of CRC regardless of socioeconomic factors.

Delays in Colorectal Cancer Screening for Latino Patients: The Role of Immigrant Healthcare in Stemming the Rising Global Incidence of Colorectal Cancer

The significant global burden of colorectal cancer accentuates disparities in access to preventive healthcare in most low- and middle-income countries (LMICs) as well as large sections of underserved populations within high-income countries. The barriers to colorectal cancer screening in economically transitioning Latin America are multiple. At the same time, immigration from these countries to the USA continues to increase. This case highlights the delays in diagnosis experienced by a recent immigrant from a country with no established colorectal cancer screening program, to an immigrant population in the USA with similar poor screening coverage. We discuss common challenges faced by Latinos in their home countries and the USA, as well as strategies that could be implemented to improve screening coverage in US immigrant populations.

Disparities in Colorectal Cancer Screening by Time in the U.S. and Race/Ethnicity, 2010-2018

INTRODUCTION

Longer time lived in the U.S. has been associated with worse health outcomes, especially preventable diseases, among racially and ethnically diverse groups of foreign-born individuals. This study evaluated the association between time lived in the U.S. and colorectal cancer screening adherence and whether this relationship differed by race and ethnicity.

METHODS

Data from the National Health Interview Survey for 2010-2018 among adults aged 50-75 years were used. Time in the U.S. was categorized as U.S.-born, foreign-born ≥15 years, and foreign-born <15 years. Colorectal cancer screening adherence was defined according to U.S. Preventive Services Task Force guidelines. Generalized linear models with Poisson distribution were used to calculate adjusted prevalence ratios and 95% CIs. Analyses were conducted in 2020-2022, were stratified by race and ethnicity, accounted for the complex sampling design, and were weighted to be representative of the U.S.

RESULTS

Prevalence of colorectal cancer screening adherence was 63% overall, 64% for U.S.-born, 55% for foreign-born ≥15 years, and 35% for foreign-born <15 years. In fully adjusted models for all individuals, only foreign-born <15 years had lower adherence than U.S.-born (foreign-born ≥15 years: prevalence ratio=0.97 [0.95, 1.00], foreign-born <15 years: prevalence ratio=0.79 [0.71, 0.88]). Results differed by race and ethnicity (p-interaction=0.002). In stratified analyses, findings for non-Hispanic White individuals (foreign-born ≥15 years: prevalence ratio=1.00 [0.96, 1.04], foreign-born <15 years: prevalence ratio=0.76 [0.58, 0.98]) and non-Hispanic Black individuals (foreign-born ≥15 years: prevalence ratio=0.94 [0.86, 1.02], foreign-born <15 years: prevalence ratio=0.61 [0.44, 0.85]) were similar to all individuals. Disparities by time in the U.S. were not observed among Hispanic/Latino individuals (foreign-born ≥15 years: prevalence ratio=0.98 [0.92, 1.04], foreign-born <15 years: prevalence ratio=0.86 [0.74, 1.01]) but persisted among Asian American/Pacific Islander individuals (foreign-born ≥15 years: prevalence ratio=0.84 [0.77, 0.93], foreign-born <15 years: prevalence ratio=0.74 [0.60, 0.93]).

CONCLUSIONS

The relationship between colorectal cancer screening adherence and time in the U.S. varied by race and ethnicity. Culturally and ethnically tailored interventions are needed to improve colorectal cancer screening adherence among foreign-born people, especially among the most recently immigrated individuals.

Barriers to Colorectal Cancer Screening in US Immigrants: A Scoping Review

INTRODUCTION

Timely colorectal cancer (CRC) screening has been shown to improve CRC-related morbidity and mortality rates. However, even with this preventative care tool, CRC screening rates remain below 70% among eligible United States (US) adults, with even lower rates among US immigrants. The aim of this scoping review is to describe the barriers to CRC screening faced by this unique and growing immigrant population and discuss possible interventions to improve screening.

METHODS

Four electronic databases were systematically searched for all original research articles related to CRC screening in US immigrants published after 2010. Following a full-text review of articles for inclusion in the final analysis, data extraction was conducted while coding descriptive themes. Thematic analysis led to the organization of this data into five themes.

RESULTS

Of the 4637 articles initially identified, 55 met inclusion criteria. Thematic analysis of the barriers to CRC screening identified five unique themes: access, knowledge, culture, trust, health perception, and beliefs. The most cited barriers were in access (financial burden and limited primary care access) and knowledge (CRC/screening knowledge).

CONCLUSIONS

US immigrants face several barriers to the receipt of CRC screening. When designing interventions to increase screening uptake among immigrants, gaps in physician and screening education, access to care, and trust need to be addressed through culturally sensitive supports. These interventions should be tailored to the specific immigrant group, since a one-size-fits approach fails to consider the heterogeneity within this population.

Sociodemographic correlates of colorectal cancer screening completion among women adherent to mammography screening guidelines by place of birth

INTRODUCTION

Colorectal cancer screening rates in the U.S. still fall short of national goals, while screening rates for other cancer sites, such as breast, remain high. Understanding characteristics associated with colorectal cancer screening among different groups of women adherent to breast cancer screening guidelines can shed light on the facilitators of colorectal cancer screening among those already engaged in cancer prevention behaviors. The purpose of this study was to explore which demographic characteristics, healthcare access factors, and cancer-related beliefs were associated with colorectal cancer screening completion among U.S. and foreign-born women adherent to mammography screening recommendations.

METHODS

Analyses of the 2015 National Health Interview Survey were conducted in 2019. A sample of 1206 women aged 50-74 who had a mammogram in the past 2 years and were of average risk for colorectal cancer was examined. Logistic regression was used to determine demographic, health service, and health belief characteristics associated with colorectal cancer screening completion.

RESULTS

Fifty-five percent of the sample were adherent to colorectal cancer screening recommendations. Women over the age of 65 (AOR = 1.76, 95% CI 1.06-2.91), with any type of health insurance, and who were bilingual (AOR = 3.84, 95% CI 1.83-8.09) were more likely to complete screening, while foreign-born women (AOR = 0.53, 95% CI 0.34-0.83) were less likely. Cancer-related beliefs did not influence adherence. Stratified analyses by nativity revealed additional associations.

CONCLUSIONS

Demographic and health service factors interact to influence colorectal cancer screening among women completing breast cancer screening. Colorectal cancer screening interventions targeting specific underserved groups and financing reforms may enhance women's colorectal cancer screening rates.

Predictors of Healthcare Access and Utilization by Syrian Americans in the United States

There are currently no studies examining healthcare access and utilization by Syrian Americans. A better understanding of the determinants of healthcare utilization among this group could help aid in the design of culturally competent programs. A self-administered survey was distributed at events across Southern California and Jacksonville, Florida from January 2018 to May 2019. Statistical analysis utilized multivariate regressions. Insurance coverage was associated with a preference for speaking Arabic (OR 0.433, p = 0.02) and increased length of residency (OR 1.04, p = 0.02). Routine checkup was associated with female sex (OR 1.97, p = 0.001), age (OR 1.05, p < 0.001), and insurance coverage (OR 6.96, p < 0.001). Colonoscopy compliance rate was 43.3% and positively associated with higher education (OR 2.70, p = 0.002), routine checkup (OR 7.61, p = 0.009) and increased length of residency (OR 1.06, p < 0.001). Syrian Americans may benefit from further health promotion campaigns with regard to insurance coverage, preventative care and cancer screenings.

Colorectal Cancer Screening and Access to Healthcare in New York City Taxi Drivers

This study examined differences in colorectal cancer screening across sociodemographic, migration, occupational, and health-related factors in a sample of male taxi drivers. Male drivers eligible for colorectal cancer screening (CRCS) (≥ 50 years old) were recruited in 55 community-based health fairs conducted during November 2015 to February 2017 in 16 taxi garages or community locations located in Queens, Brooklyn, Manhattan and Bronx. Participants completed a survey that included sociodemographic, migration, occupational, health-related, and cancer screening practices. For this study 33 questions were analyzed. The sample consisted of 137 male drivers, 27% of them had undergone CRCS. Occupation-related factors, including night shifts and driving high numbers of weekly hours, were associated with lower CRCS rates; having a family history of cancer, health insurance, a regular source of primary care, and a routine check-up in the last year, were associated with higher CRCS rates. The findings suggest that drivers with health insurance and better access to primary care are more likely to be up-to-date with CRCS. The results provide important information that can inform occupation-based public health interventions.

A national study of gender and racial differences in colorectal cancer screening among foreign-born older adults living in the US

This study examined within group heterogeneity in colorectal cancer screening (CRCS) among foreign-born individuals. Data were from the 2010, 2013 and 2015 National Health Interview Survey data on older adults (N = 5529). In 2018, multivariable logistic regression analysis was conducted to determine whether gender and race/ethnicity were associated with CRCS after controlling for sociodemographic, health access, and acculturation related factors. Overall, Asians were significantly less likely to report CRCS compared with Whites (aOR 0.63, CI 0.52-0.76). Hispanic race/ethnicity was negatively associated with CRCS among men (aOR 0.68, CI 0.50-0.91), but not women compared to white men/women, respectively. Additionally, factors associated with CRCS include having fair/poor health, usual source of care, insurance, ≥ 10 years of US residency and citizenship. Screening disparities experienced by these immigrants may be addressed by improving healthcare access, especially for noncitizens and those with limited healthcare access.

Barriers to Healthcare among African Immigrants in Georgia, USA

African-born immigrants are among the fastest growing immigrant groups in the US, yet they are underrepresented in healthcare research, particularly, cancer research and tend to be categorized as African American or Black, obscuring any cultural nuances that exist. A survey designed to provide insight on the barriers to healthcare, knowledge of common cancers, and cancer risks was utilized during a health fair. Data analyses included descriptive statistics to examine participant demographics and other study variables of interest. Most of the participants reported African origin (approximately 97%), were males (59%), were aged 18-40 years (49%), had a minimum of some college education (78%), a household income of >$50,000 (35%) and were mostly uninsured (45%). The cost of medical treatment 19 (45.2%) was reported as a major barrier to healthcare access. The Health Fair presented the opportunity to provide free health screenings, education/awareness, and referral to follow-up resources. The findings are evidence of the importance and impact of health fairs in communities of greatest need.

Early Colorectal Cancer Detected by Machine Learning Model Using Gender, Age, and Complete Blood Count Data

BACKGROUND

Machine learning tools identify patients with blood counts indicating greater likelihood of colorectal cancer and warranting colonoscopy referral.

AIMS

To validate a machine learning colorectal cancer detection model on a US community-based insured adult population.

METHODS

Eligible colorectal cancer cases (439 females, 461 males) with complete blood counts before diagnosis were identified from Kaiser Permanente Northwest Region's Tumor Registry. Control patients (n = 9108) were randomly selected from KPNW's population who had no cancers, received at ≥1 blood count, had continuous enrollment from 180 days prior to the blood count through 24 months after the count, and were aged 40-89. For each control, one blood count was randomly selected as the pseudo-colorectal cancer diagnosis date for matching to cases, and assigned a "calendar year" based on the count date. For each calendar year, 18 controls were randomly selected to match the general enrollment's 10-year age groups and lengths of continuous enrollment. Prediction performance was evaluated by area under the curve, specificity, and odds ratios.

RESULTS

Area under the receiver operating characteristics curve for detecting colorectal cancer was 0.80 ± 0.01. At 99% specificity, the odds ratio for association of a high-risk detection score with colorectal cancer was 34.7 (95% CI 28.9-40.4). The detection model had the highest accuracy in identifying right-sided colorectal cancers.

CONCLUSIONS

ColonFlag^® identifies individuals with tenfold higher risk of undiagnosed colorectal cancer at curable stages (0/I/II), flags colorectal tumors 180-360 days prior to usual clinical diagnosis, and is more accurate at identifying right-sided (compared to left-sided) colorectal cancers.

Colonoscopy and sigmoidoscopy use among older adults in different countries: A systematic review

Screening for colorectal cancer (CRC) by colonoscopy and sigmoidoscopy has been demonstrated to be effective in reducing CRC incidence and mortality, and they are increasingly employed as screening tests and for diagnostic purposes in many countries. We conducted a systematic review to provide up-to-date estimates on the utilization of lower gastrointestinal endoscopy (colonoscopy and sigmoidoscopy) in the general average-risk population in different countries. PubMed and Web of Science were searched for relevant articles published between 1 September 2008 and 31 October 2016. A total of 23 studies from the US and 20 studies from other countries were included in this review. Estimates from the US were highest, continued to increase over the past decade and reached 62% for colonoscopy use within 10years in people aged 50-75years in 2012. Endoscopy use in other countries was substantially lower (12-44% for lifetime colonoscopy use and 13-30% for recent colonoscopy use), except for Germany, where 55% of the screening-eligible population reported colonoscopy utilization within the previous 10years in 2008-2011. Both lifetime and recent endoscopy use increased with age and peaked at approximately 70-75years. Although several European and Asian countries have started to collect endoscopy utilization data through periodic national health surveys, more data are still much needed from non-US countries. With the implementation of CRC screening programs in an increasing number of countries, especially European countries, an increase in endoscopy use and subsequent reduction in CRC incidence and mortality in the years to come might be expected in those countries.

Predictors of colorectal cancer screening awareness among people working in a hospital environment

Background

Compliance rates for colorectal cancer (CRC) screening are much lower than those desired. Appropriate information on CRC risks and screening methods is supposed to stimulate motivation for screening. We aimed to identify parameters associated with the decision for CRC screening and colonoscopy in a population expected to have high awareness of disease prevention.

Methods

In a single-center, cross-sectional study, we used an anonymous questionnaire (AQ) to record the demographics, habits and screening behavior for cancers and other common diseases of all employees older than 50 years in our hospital.

Results

Among 287 active employees, 83% (n=237) answered the AQ (age 55±4 years). Thirty percent (n=70) underwent colonoscopy while 17% (n=40) underwent CRC screening (39/40) colonoscopy). Comparatively, among women 97% had a Pap-smear, 92% a mammography, while among men 83% had been tested for serum prostate-specific antigen. Age, male sex, alcohol consumption and university education correlated positively with CRC screening (P<0.05 for all). After multivariate analysis, university education remained an independent determinant of CRC screening (OR 2.488, 95%CI 1.096-5.648; P=0.029). Among subjects who had not undergone colonoscopy in the past, ignorance of the need for CRC screening (OR 0.360, 95%CI 0.150-0.867; P=0.023) and indifference to undergo such a procedure (OR 0.188, 95%CI 0.066-0.537; P=0.002) were independent determinants for not planning a future screening colonoscopy.

Conclusions

Education was the most important factor in the decision to undergo CRC screening. Colonoscopy was the preferred screening method. Ignorance of and indifference to CRC risks were the major obstacles for a future screening colonoscopy.

Colorectal cancer screening: Opportunities to improve uptake, outcomes, and disparities

Colorectal cancer screening has become a standard of care in industrialized nations for those 50 to 75 years of age, along with selected high-risk populations. While colorectal cancer screening has been shown to reduce both the incidence and mortality of colorectal cancer, it is a complex multi-disciplinary process with a number of important steps that require optimization before tangible improvements in outcomes are possible. For both opportunistic and programmatic colorectal cancer screening, poor participant uptake remains an ongoing concern. Furthermore, current screening modalities (such as the guaiac based fecal occult blood test, fecal immunochemical test and colonoscopy) may be used or performed suboptimally, which can lead to missed neoplastic lesions and unnecessary endoscopic evaluations. The latter poses the risk of adverse events, such as perforation and post-polypectomy bleeding, as well as financial impacts to the healthcare system. Moreover, ongoing disparities in colorectal cancer screening persist among marginalized populations, including specific ethnic minorities (African Americans, Hispanics, Asians, Indigenous groups), immigrants, and those who are economically disenfranchised. Given this context, we aimed to review the current literature on these important areas pertaining to colorectal cancer screening, particularly focusing on the guaiac based fecal occult blood test, the fecal immunochemical test and colonoscopy.

Diagnostic colonoscopy following a positive fecal occult blood test in community health center patients

PURPOSE

Fecal occult blood testing (FOBT) is a pragmatic screening option for many community health centers (CHCs), but FOBT screening programs will not reduce mortality if patients with positive results do not undergo diagnostic colonoscopy (DC). This study was conducted to investigate DC completion among CHC patients.

METHODS

This retrospective cohort study used data from three CHCs in the Midwest and Southwest. The primary study outcome was DC completion within 6 months of positive FOBT among adults age 50-75. Patient data was collected using automated electronic queries. Manual chart reviews were conducted if queries produced no evidence of DC. Poisson regression models described adjusted relative risks (RRs) of DC completion.

RESULTS

The study included 308 patients; 63.3 % were female, 48.7 % were Spanish speakers and 35.7 % were uninsured. Based on combined query and chart review findings, 51.5 % completed DC. Spanish speakers were more likely than English speakers to complete DC [RR 1.19; 95 % confidence interval (CI) 1.04-1.36; P = 0.009], and DC completion was lower among patients with 0 visits than those with 1-2 visits (RR 2.81; 95% CI 1.83-4.33; P < 0.001) or ≥3 visits (RR 3.06; 95% CI 1.57-5.95; P = 0.001).

CONCLUSIONS

DC completion was low overall, which raises concerns about whether FOBT can reduce CRC mortality in practice. Further research is needed to understand whether CHC navigator programs can achieve very high DC rates. If organizations use FOBT as their primary CRC screening approach and a substantial number of patients receive positive results, both screening rates and DC rates should be measured.

Socioeconomic Disparities in Colorectal Cancer Screening in Korea: A Nationwide Cross-Sectional Study

Colorectal cancer (CRC) is a common cancer worldwide. The incidence and mortality rates of CRC are higher among lower socioeconomic status (SES) populations. We investigated the association between different indicators of SES and CRC screening rates in Korea. The eligible study population included males and females aged 50 to 74 years who participated in a nationwide cross-sectional survey (2010-2012). The "compliance with recommendation" category was applicable to participants who had undergone a fecal occult blood test (FOBT), double-contrast barium enema, or colonoscopy within 1, 5, or 10 years, respectively. In total, 6221 subjects (51.4% female, 55.6% aged 50 years) were included in the final analysis. Lower household income was significantly negatively related to compliance with screening recommendations (P for trend < 0.01) and marginally significantly related to noncompliance with recommendations (P for trend = 0.07). Older age and poor self-reported health were associated with the screening rate using the FOBT; male sex, older age, higher household income, having supplemental insurance, family history of cancer, and poor self-reported health were associated with a higher screening rate using colonoscopy. Lower household income was associated with a higher screening rate using the FOBT and with a lower screening rate using colonoscopy. To increase the rate of CRC screening using colonoscopy, efforts should be made toward improving the education and promotion of screening to the low household income target population.

Leading Causes of Death among Asian American Subgroups (2003-2011)

BACKGROUND

Our current understanding of Asian American mortality patterns has been distorted by the historical aggregation of diverse Asian subgroups on death certificates, masking important differences in the leading causes of death across subgroups. In this analysis, we aim to fill an important knowledge gap in Asian American health by reporting leading causes of mortality by disaggregated Asian American subgroups.

METHODS AND FINDINGS

We examined national mortality records for the six largest Asian subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese) and non-Hispanic Whites (NHWs) from 2003-2011, and ranked the leading causes of death. We calculated all-cause and cause-specific age-adjusted rates, temporal trends with annual percent changes, and rate ratios by race/ethnicity and sex. Rankings revealed that as an aggregated group, cancer was the leading cause of death for Asian Americans. When disaggregated, there was notable heterogeneity. Among women, cancer was the leading cause of death for every group except Asian Indians. In men, cancer was the leading cause of death among Chinese, Korean, and Vietnamese men, while heart disease was the leading cause of death among Asian Indians, Filipino and Japanese men. The proportion of death due to heart disease for Asian Indian males was nearly double that of cancer (31% vs. 18%). Temporal trends showed increased mortality of cancer and diabetes in Asian Indians and Vietnamese; increased stroke mortality in Asian Indians; increased suicide mortality in Koreans; and increased mortality from Alzheimer's disease for all racial/ethnic groups from 2003-2011. All-cause rate ratios revealed that overall mortality is lower in Asian Americans compared to NHWs.

CONCLUSIONS

Our findings show heterogeneity in the leading causes of death among Asian American subgroups. Additional research should focus on culturally competent and cost-effective approaches to prevent and treat specific diseases among these growing diverse populations.

Colorectal cancer screening among Latinos in three communities on the Texas-Mexico border

OBJECTIVE

To assess colorectal cancer screening (CRCS) prevalence and psychosocial correlates of CRCS among Latinos in South Texas.

METHOD

Using multivariable analyses, we examined the association of perceived susceptibility, self-efficacy, pros and cons, subjective norms, knowledge and fatalism on CRCS among 544 Latinos (50 years and older).

RESULTS

In this socioeconomically disadvantaged population, 40% had never heard of any CRCS test, only 34% reported ever completing any type of CRCS, and only 25% were adherent to CRCS guidelines. Insurance status, gender, perceived cons, CRCS self-efficacy, and CRCS norms were significantly associated with CRCS.

CONCLUSION

CRCS interventions in this population should focus on improving access, increasing self-efficacy and perceived norms, and decreasing negative perceptions of CRCS.

Patient and provider characteristics associated with colorectal, breast, and cervical cancer screening among Asian Americans

BACKGROUND

Routinely recommended screening for breast, cervical, and colorectal cancers can significantly reduce mortality from these types of cancer, yet screening is underutilized among Asians. Surveys rely on self-report and often are underpowered for analysis by Asian ethnicities. Electronic health records (EHR) include validated (as opposed to recall-based) rates of cancer screening. In this article, we seek to better understand cancer screening patterns in a population of insured Asian Americans.

METHODS

We calculated rates of compliance with cervical, breast, and colorectal cancer screening among Asians from an EHR population and compared them with non-Hispanic whites. We performed multivariable modeling to evaluate potential predictors (at the provider- and patient-level) of screening completion among Asian patients.

RESULTS

Aggregation of Asian subgroups masked heterogeneity in screening rates. Asian Indians and native Hawaiians and Pacific Islanders had the lowest rates of screening in our sample, well below that of non-Hispanic whites. In multivariable analyses, screening completion was negatively associated with patient-physician language discordance for mammography [OR, 0.81; 95% confidence interval (CI), 0.71-0.92] and colorectal cancer screening (OR, 0.79; CI, 0.72-0.87) and positively associated with patient-provider gender concordance for mammography (OR, 1.16; CI, 1.00-1.34) and cervical cancer screening (OR, 1.66; CI, 1.51-1.82). In addition, patient enrollment in online health services increased mammography (OR, 1.32; CI, 1.20-1.46) and cervical cancer screening (OR, 1.31; CI, 1.24-1.37).

CONCLUSIONS

Language- and gender-concordant primary care providers and culturally tailored online health resources may help improve preventive cancer screening in Asian patient populations.

IMPACT

This study demonstrates how the use of EHR data can inform investigations of primary prevention practices within the healthcare delivery setting.

Addressing cancer control needs of African-born immigrants in the US: a systematic literature review

Compared to non-Hispanic Whites, African immigrants have worse cancer outcomes. However, there is little research about cancer behaviors and/or interventions in this growing population as they are generally grouped with populations from America or the Caribbean. This systematic review examines cancer-related studies that included African-born participants. We searched PsycINFO, Ovid Medline, Pubmed, CINHAL, and Web of Science for articles focusing on any type of cancer that included African-born immigrant participants. Twenty articles met study inclusion criteria; only two were interventions. Most articles focused on one type of cancer (n=11) (e.g., breast cancer) and were conducted in disease-free populations (n=15). Studies included African participants mostly from Nigeria (n=8) and Somalia (n=6). However, many papers (n=7) did not specify nationality or had small percentages (<5%) of African immigrants (n=5). Studies found lower screening rates in African immigrants compared to other subpopulations (e.g. US-born). Awareness of screening practices was limited. Higher acculturation levels were associated with higher screening rates. Barriers to screening included access (e.g. insurance), pragmatic (e.g. transportation), and psychosocial barriers (e.g. shame). Interventions to improve cancer outcomes in African immigrants are needed. Research that includes larger samples with diverse African subgroups including cancer survivors is necessary to inform future directions.

Barriers to HIV Testing in Black Immigrants to the U.S

BACKGROUND

Late HIV testing is common among immigrants from sub Saharan Africa and the Caribbean. Since 2010, HIV testing is no longer a required component of immigrant screening examinations or mandatory for immigrants seeking long term residence in the US. Thus, barriers to HIV testing must be addressed.

METHODS

Five hundred and fifty-five (555) immigrants completed a barriers-to-HIV testing scale. Univariate and multivariate linear regression were performed to examine predictors of barriers.

RESULTS

In multivariate analysis, primary language other than English (β=2.9, p=.04), lower education (β=5.8, p=.03), low income [= below $20K/year] (β=4.6, p=.01), no regular provider (β=5.2, p=.002) and recent immigration (β=5.7, p=.0008) were independently associated with greater barriers. Barriers due to health care access, privacy, fatalism, and anticipated stigma were greater for recent versus longer term immigrants.

DISCUSSION

Immigrants from sub-Saharan Africa and the Caribbean face significant barriers to HIV testing. Interventions to improve access and timely entry into care are needed.

Rural disparities in receipt of colorectal cancer screening among adults ages 50-64 with disabilities

BACKGROUND

Colorectal cancer is the third leading cause of cancer deaths in the United States. Early detection can reduce mortality; however, only 59% of U.S. adults age 50 and over meet recommended colorectal cancer screening guidelines. Studies in the general population have observed that rural residents are less likely to have received colorectal cancer screening than residents of urban areas.

OBJECTIVE

To determine whether urban/rural disparities in colorectal cancer screening exist among people with disabilities, similar to the disparities found in the general population.

METHODS

We analyzed Medical Expenditure Panel Survey annual data files from 2002 to 2008. We conducted logistic regression analyses to examine the relationship between urban/rural residence and ever having received screening for colorectal cancer (via colonoscopy, sigmoidoscopy, or fecal occult blood test).

RESULTS

Among U.S. adults ages 50-64 with disabilities, those living in rural areas were significantly less likely to have ever received any type of screening for colorectal cancer. The urban/rural difference was statistically significant regardless of whether or not we controlled for demographic, socioeconomic, health, and health care access variables.

CONCLUSIONS

Disparity in screening for colorectal cancer places rural residents with disabilities at greater risk for late stage diagnosis and mortality relative to people with disabilities in urban areas. Thus, there is a need for strategies to improve screening among people with disabilities in rural areas.

Reluctance to screening colonoscopy in Arab Americans: a community based observational study

To explore compliance of Arab-Americans to colorectal cancer (CRC) screening and identify the barriers for non-compliance. An observational community based study. Arab-American Friday prayer attendees' ≥50 years in three mosques in Dearborn, MI volunteered. Demographics, health insurance status, screening history, availability of a primary care physician (PCP) and the ability to communicate in Arabic were inquired. The responses were compared using a student t test between respondents who have had CRC screening with colonoscopy and those who have not had any screening tests. A p value of 0.05 or lower was considered statistically significant. Total number surveyed was 130. Average age is 64 years. Males were 76 % (99) and females 24 % (31). More than 50 % were Lebanese and 28 % were from Yemen. Majority had health insurance (89 %), and 86 % had a primary care physician of which 79 % of them spoke Arabic. Half of the participants had colonoscopy mostly for screening purposes. Fifty-eight (45 %) participants did not have CRC screening. Majority of the females (72.4 %) had colonoscopy compared to 46.8 % of the males (p value = 0.016). The mean length of stay in the U.S was 39.16 years in the colonoscopy group compared to 30.77 years in the non-screening group (p value = 0.006). Participants without a PCP did not have CRC screening (77.8 %) (p value = 0.005). Participants with a non-Arabic speaking PCP had more colonoscopy rates (77.3 %) compared to those with an Arabic speaking PCP (50 %) (p value = 0.027). More Lebanese had colonoscopy (71.9 %) compared to 25.7 % of the surveyed Yemenis (p value = 0.00). Discomfort, unawareness about CRC screening, and nonrecommendation by PCP were reported barriers. Arab-Americans have lower screening colonoscopy rates. Unfamiliarity of the importance of screening is a principal issue. Having a non-arabic speaking PCP is beneficial. Better education to this population about the benefits and ease of screening could increase adherence to screening for this population.
