Predictors of older Korean Americans' participation in colorectal cancer screening

Colorectal Cancer Screening Challenges in the Recent Afghan Refugee Population: A Comprehensive Review Article

Colorectal cancer (CRC) is more prevalent in south-central Asian countries, particularly the Afghan population. Screening for CRC in the Afghan population has always been challenging, primarily due to the tribal and social cultures, lack of facilities, and lack of education. The United States (US) will soon face a significantly massive influx of Afghan refugees. It becomes imperative to initiate and implement effective measures regarding CRC screening in these refugee populations. The current review article aims to identify the most likely challenges faced for CRC screening in this Afghan refugee population in the US and address the possible measures to overcome these challenges.

Colorectal cancer and potential predictors of never screened for faecal occult blood test: a narrative review

Colorectal cancer (CRC) is a major public health threat. Therefore, CRC screening uptake has been a focus with the established precancerous lesion and the strong association of early detection with staging and survival of the disease. However, CRC screening is relatively low in many countries. This article briefly discussed the current situation of CRC, recommendations, and current uptake of CRC screening in various countries. Besides that, this article also highlights the potential factors that help to predict the CRC screening uptake worldwide. Identification of those factors could guide policymakers to develop an effective strategy to improve the CRC screening uptake and ultimately improve the health outcome of the population.

Barriers and facilitators to colorectal cancer screening among older Korean Americans: A focus group study

A qualitative study was undertaken to explore the barriers and facilitators to colorectal cancer (CRC) screening among older Korean Americans (KAs). Four focus groups with 25 male and female KA participants and one focus group comprising five KA health professionals were conducted in the Atlanta Metropolitan area. Interpretive analyses of the interview data revealed barriers regarding CRC screening for KAs included a lack of CRC knowledge, embarrassment during the screening tests, CRC-related fatalism, and modesty, no perceived need for the screening, poor English proficiency, and mistrust of the American healthcare system. The results also indicated that doctors' screening recommendations and access to Korean doctors positively influence KAs' decision to participate in CRC screening. Public health social workers should consider integrating age- and gender-specific cultural contexts when developing interventions and programs for CRC screening targeted to older KAs.

Factors Influencing Colorectal Cancer Screening Among Thais in the U.S

This study examined factors related to colorectal cancer (CRC) screening uptake among Thais in the United States. A total of 121 Thais between 50 and 75 years of age, who were married and living in southern California participated in the survey (mean age = 61 years). Out of all the participants, only 21% of the participants had fecal occult blood tests, 21% had sigmoidoscopy, and 45% had colonoscopy that were within the recommended period. Overall, 55% of participants met CRC screening adherence criteria. Participants who had had regular checkups in the previous 2 years without having any symptoms were 16 times more likely to have obtained CRC screening than their counterparts (OR 16.01, CI 3.75-68.75) in the multivariable logistic regression model. Other significant predictors of screening adherence included older age (OR 1.08, 95% CI 1.00-1.17), having lived in the U.S. 15 years or longer (OR 6.65, 95% CI 1.55-28.59), having had at least some college education (OR 3.74, 95% CI 1.23-11.37), and higher levels of perceived self-efficacy (OR 1.88, 95% CI 1.01-3.50) to obtain CRC screening. Targeted interventions for Thais who are less likely receive CRC screening could be effective in improving CRC screening. Interventions to improve the populations' awareness of the importance of preventive measures when they are not sick could be also effective.

Rapid review of factors associated with flexible sigmoidoscopy screening use

Flexible sigmoidoscopy (FS) screening has been shown to reduce colorectal cancer (CRC) incidence and mortality among screened adults. The aim of this review was to identify patient-related factors associated with the screening test's use. We searched PubMed for studies that examined the association between FS screening use and one or more factors. To determine the eligibility of studies, we first reviewed titles, then abstracts, and finally the full paper. We started with a narrow search, which we expanded successively (by adding 'OR' terms) until the number of new publications eligible after abstract review was <1% of the total number of publications. We then abstracted factors from eligible papers and reported the number of times each was found to be positively or negatively associated with FS screening use. We identified 42 papers, most of which reported studies conducted in the United States of America (n = 21, 50%) and the United Kingdom (n = 13, 31%). Across studies, a wide range of factors were examined (n = 123), almost half of which were found to be associated with FS screening use at least once (n = 60). Sociodemographic and health and lifestyle factors that were frequently positively associated with FS screening use included: male gender, higher socioeconomic status and a family history of CRC. Frequently positively associated psychosocial factors included low perceived barriers and high perceived benefits. Findings suggest that future research should focus on developing a theoretical framework of cancer screening behaviour to allow a greater level of consistency and specificity in measuring key constructs.

The Chinese and Korean American immigrant experience: a mixed-methods examination of facilitators and barriers of colorectal cancer screening

OBJECTIVE

Among Asian Americans, colorectal cancer (CRC) is the second leading cause of cancer deaths. Despite strong evidence that screening can reduce CRC-related mortality, fewer Chinese and Koreans receive screening as compared to non-Hispanic whites and blacks. The objective of this study was to examine facilitators and barriers as well as strategies to promote CRC screening in this population.

DESIGN

This study employed a mixed-methods design. We conducted 17 key informant interviews and 12 focus groups in the Washington, D.C. metropolitan area. 120 Chinese and Korean focus group participants, aged 50 to 85, also provided quantitative data through self-administered surveys. All participants were asked to discuss facilitators and barriers of CRC screening, including in relation to culture.

RESULTS

Participants who had a regular physician and doctor's recommendation for CRC screening were more likely to ever receive a colonoscopy (adjusted odds ratio (aOR) = 3.51; 95% confidence interval (CI): 1.26, 9.79 and aOR = 6.61; 95% CI: 2.63, 16.65, respectively). A doctor's recommendation was also significantly associated with receipt of a fecal occult blood test (FOBT) (aOR = 4.00; 95% CI: 1.43, 11.15). In terms of barriers, those who reported having no time and not having symptoms were less likely to have a colonoscopy (aOR = 0.15; 95% CI: 0.03, 0.82 and aOR = 0.02; 95% CI: 0.002, 0.23, respectively) than those who had time and symptoms. Preventive healthcare was often not viewed as a priority, particularly for those living the'immigrant life,' who gave precedence to work. Cultural barriers to CRC screening included language (e.g. limited English proficiency and low health literacy); fear of finding CRC and burdening the family especially children; fatalism; and stigma towards cancer.

CONCLUSIONS

Future interventions and programs aiming to increase CRC screening among Chinese and Korean Americans should address both cultural and non-cultural factors that influence CRC screening uptake.

Colorectal Cancer Screening among Korean Americans in Chicago: Does It Matter Whether They had the Screening in Korea or the US?

Background:

Colorectal cancer (CRC) is one of the most common cancers in Korean Americans (KAs) and CRC screening can detect CRC early and may reduce the incidence of CRC by leading to removal of precancerous polyps. Many KAs in the US leave the country, primarily to travel to Korea, for health screening. The aim of this study was to (a) assess CRC screening rates, including fecal occult blood test (FOBT), flexible sigmoidoscopy, and colonoscopy and (b) explore factors related to these tests among KAs by location of CRC screening.

Methods:

Descriptive and correlational research design with cross-sectional surveys was used with 210 KAs. Socio-demographics (age, gender, years in the US, marital status, education, employment, household income, and proficiency in spoken English), access to health care (health insurance and usual source of health care), and location of CRC screening utilization (Korea, the US, or both Korea and US) were measured and analyzed using descriptive statistics and multinominal logistic regression.

Results:

Out of 133 KA participants who had had lifetime CRC screening (i.e., had ever had FOBT, flexible sigmoidoscopy, or colonoscopy), 19% had visited Korea and undergone CRC screening in their lifetimes. Among socio-demographic factors and access to health care factors, having a usual source of health care in the US (OR=8.45) was significantly associated with having undergone lifetime CRC screening in the US. Having health insurance in the US and having had lifetime CRC screening in the US were marginally significant (OR=2.54).

Conclusion:

Access to health care in the US is important for KAs to have CRC screening in the US. As medical tourism has been increasing globally, the location of CRC screening utilization must be considered in research on cancer screening to determine correlates of CRC screening.

Unraveling the Determinants to Colorectal Cancer Screening Among Asian Americans: a Systematic Literature Review

Colorectal cancer (CRC) is one of the top three cancers experienced among Asian American (AA) men and women. One effective way to decrease incidence and mortality from CRC is the adherence of regular CRC screening; however, AA continue to receive the lowest screening rates compared to other racial/ethnic groups. When disaggregating this heterogeneous population, further disparities exist between subgroups. Examination of facilitators and barriers to cancer screening among AA subgroups is fairly recent and the synthesis of this information is limited. As such, a systematic review was conducted examining the facilitators and the barriers among Chinese, Filipino, Korean, and Japanese Americans using a systematic literature review method. The Health Belief Model served as the primary theoretical framework for this study and used to organize and synthesize the facilitators and barriers to CRC screening. In total, 22 articles yielded 29 examinations of each of the AA subgroups. Different facilitators and barriers to screening uptake for each subgroup were revealed; however, consistent across all the subgroups was physician recommendation as a facilitator and participants' unawareness of screening tests and those stating having no problems/symptoms of CRC as a barrier across screening modalities. Tailored approach in outreach and intervention efforts are suggested when achieving to improve CRC screening in AA ethnic subgroups.

Understanding breast cancer screening behaviors of Korean American women in sociocultural contexts

This study examines the breast cancer screening behaviors of Korean American women focusing on their cultural beliefs and access to health care. A total of 111 Korean American women participated in the cross-sectional survey research. Korean American women who felt embarrassed about breast cancer screenings were less likely to have received clinical breast exams or mammograms. Implications to culturally competent social work practice in promoting their breast cancer screening behaviors are discussed.

Cultural Factors Associated with Breast and Cervical Cancer Screening in Korean American Women in the US: An Integrative Literature Review

PURPOSE

This study examined current research theories and methods, cultural factors, and culturally relevant interventions associated with breast and cervical cancer screening in Korean American (KA) women.

METHODS

Based on Ganong's guidelines, the literature on cultural factors associated with breast and cervical cancer screening in KA women was searched using MEDLINE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Sixty-eight articles on breast cancer screening and 66 articles on cervical cancer screening were retrieved from both databases, and a total of 22 articles were included in the literature review based on the selection criteria.

RESULTS

Of the 22 studies reviewed, 14 (63.6%) were descriptive and 8 (36.4%) were interventional. Many studies have used individual focused cognitive theories such as health belief model and different types of operationalization for measures of cultural beliefs. Cultural factors associated with breast and cervical cancer screening in KA women that were identified in descriptive quantitative and qualitative studies included family, embarrassment, preventive health orientation, fatalism, and acculturation. Most culturally relevant interventional studies used education programs, and all education was conducted by bilingual and bicultural health educators at sociocultural sites for KA women.

CONCLUSIONS

Theories focusing on interpersonal relationships and standardized, reliable, and valid instruments to measure cultural concepts are needed to breast and cervical cancer screening research in KA women. Traditional cultural factors associated with cancer screening should be considered for practical implications and future research with KA women.

Differences in knowledge, attitudes, beliefs, and perceived risks regarding colorectal cancer screening among Chinese, Korean, and Vietnamese sub-groups

Asian ethnic subgroups are often treated as a single demographic group in studies looking at cancer screening and health disparities. To evaluate knowledge and health beliefs associated with colorectal cancer (CRC) and CRC screening among Chinese, Korean, and Vietnamese subgroups, a survey assessed participants' demographic characteristics, healthcare utilization, knowledge, beliefs, attitudes associated with CRC and CRC screening. Exploratory factor analysis identified six factors accounting >60 % of the total variance in beliefs and attitudes. Cronbach's alpha coefficients assessed internal consistency. Differences among Asian subgroups were assessed using a Chi square, Fisher's exact, or Kruskal-Wallis test. Pearson's correlation coefficient assessed an association among factors. 654 participants enrolled: 238 Chinese, 217 Korean, and 199 Vietnamese. Statistically significant differences existed in demographic and health care provider characteristics, knowledge, and attitude/belief variables regarding CRC. These included knowledge of CRC screening modalities, reluctance to discuss cancer, belief that cancer is preventable by diet and lifestyle, and intention to undergo CRC screening. Chinese subjects were more likely to use Eastern medicine (52 % Chinese, 25 % Korean, 27 % Vietnamese; p < 0.001); Korean subjects were less likely to see herbs as a form of cancer prevention (34 % Chinese, 20 % Korean, 35 % Vietnamese; p < 0.001). Vietnamese subjects were less likely to consider CRC screening (95 % Chinese, 95 % Korean, 80 % Vietnamese; p < 0.0001). Important differences exist in knowledge, attitudes, and health beliefs among Asian subgroups. Understanding these differences will enable clinicians to deliver tailored, effective health messages to improve CRC screening and other health behaviors.

Colorectal cancer screening among Korean Americans: a systematic review

The incidence of colorectal cancer (CRC) among Korean Americans (KAs) has increased in recent years, even as the rate in nearly ever other population group in the United States has decreased. Reversing this trend will require improving screening rates, but a variety of sociocultural factors may inhibit this goal. We conducted a systematic review of the published literature on cancer screening among KAs, and identified thirteen eligible studies that examined CRC screening. KAs have CRC screening rates that are significantly lower than the national average. Only about one in four KAs ages 50 and older reports having ever had a fecal ocult blood test (FOBT) and only about 40 % have ever had a sigmoidoscopy or colonoscopy. KA adults are also significantly less likely than the general US population to say they have heard of FOBT, sigmoidoscopy, or colonoscopy. In the KA population, screening rates are higher among adults with higher socioeconomic status, greater acculturation to the United States, more cancer knowledge, more social support, and better access to healthcare services. Improving cultural and financial access to health education and healthcare services may increase CRC screening among KAs and reduce the incidence of the disease.

Older Korean American men's prostate cancer screening behavior: the prime role of culture

East and South Asian male immigrants show markedly low odds of prostate cancer screening as compared to U.S.-born men. However, knowledge about these immigrants' culture-based screening behavior and barriers to screening is extremely limited. This study investigates factors influencing receipt of prostate cancer screening among Korean American immigrant men, particularly investigating culture's impact on screening behaviors. Data were collected through a convenience and purposive sampling technique from 134 Korean American males aged 50 and older recruited in New York City. A structured questionnaire was used and cultural variables were measured by adopting items from Tang and colleagues' work. Approximately 60 % of the sample had received a prostate-specific antigen (PSA) test in their lifetime, and of these, about 66 % reported having done so in the previous 12 months. Logistic regression analysis revealed that a crisis-oriented intervention approach was associated with a substantially reduced likelihood of screening. A positive correlation was noted between the use of Eastern medicine and PSA test receipt. Further analysis revealed a significant interaction effect between use of Eastern medicine and age in predicting PSA test uptake. Culture-specific intervention strategies for increasing prostate cancer screening in this group are discussed, with particular attention to increasing pertinent health literacy. Health professionals should consider the cultural domain when working with Korean immigrant men in order to provide culturally competent care.

Improving colorectal cancer screening in Asian Americans: Results of a randomized intervention study

BACKGROUND

The objective of this study was to use a randomized controlled trial design to test the impact of an educational intervention delivered by specially trained community health workers among Chinese, Korean, and Vietnamese participants ages 50 to 75 years on knowledge, attitudes, beliefs, and intentions regarding colorectal cancer screening.

METHODS

Baseline data were collected on participants' demographic characteristics, knowledge, attitudes, beliefs about cancer, its risk factors, and intention to keep up to date on cancer screening in the future. Fifteen intervention sessions were held between April and June of 2011. Follow-up surveys were administered in the postintervention period to both intervention and control participants. Those randomized to the control group received educational pamphlets in their native language.

RESULTS

The intervention had the greatest influence on the Chinese subgroup, which had improved scores relative to the control group for perceived behavior control and intentions (preintervention vs postintervention change: control group, -0.16; intervention group, 0.11; P = .004), behavioral beliefs on cancer screening (preintervention vs postintervention change: control group, -0.06; intervention group, 0.24; P = .0001), and attitudes toward behavior (preintervention vs postintervention change: control group, -0.24; intervention group, 0.35; P ≤ .0001). The intervention had no effect on behavioral beliefs about cancer, control beliefs, or perceived behavioral control (reliance on family). Although the intention to stay up to date for cancer screening increased in 2 study groups (Chinese and Vietnamese), these increases were not significant.

CONCLUSIONS

An educational program delivered by culturally specific community health educators using culturally appropriate language influences some knowledge, attitude, and behavioral beliefs but not others.

Impact of Asian Ethnicity on Colorectal Cancer Screening

OBJECTIVES

Although research shows that African Americans and Hispanics frequently receive less colorectal cancer screening (CRCS) than whites, few studies have focused on CRCS among Asians. The aims of this study were to compare CRCS between Asians and whites and to evaluate for clinical predictors of CRCS.

METHODS

From the 2007 California Health Interview Survey, we identified all Asian and white respondents who were eligible for CRCS. Logistic regression was performed to evaluate for differences in CRCS. We used stratified and interaction analyses to examine whether associations between race and CRCS were modified by insurance status, birthplace, or language skills, while controlling for other confounders.

RESULTS

Baseline characteristics were similar between Asians and whites. Only 58% of Asians and 66% of whites reported undergoing up-to-date CRCS (P < 0.01). In multivariate analyses, visiting a physician more than 5 times produced the highest odds of being up-to-date with screening. When compared with whites, Asians had decreased odds of being up-to-date with screening. Stratified analyses showed that this disparity existed mainly in the insured, but not in the uninsured, and it was not modified by place of birth or English language proficiency.

CONCLUSIONS

Despite its ability to reduce mortality, CRCS is suboptimal in our US population-based cohort of Asians when compared with whites. A contributing factor to this problem for the Chinese and Koreans may be a lack of awareness regarding CRCS, whereas the source of the problem in the Vietnamese seems to be related to healthcare access.

Factors Associated with Colorectal Cancer Screening Among Cambodians, Vietnamese, Koreans and Chinese Living in the United States

The purpose of this community-based participatory study was to identify factors associated with colorectal cancer (CRC) screening compliance and non-compliance among Cambodians, Vietnamese, Koreans and Chinese men and women 50 years and older living in the United States. A cross-sectional design was used in the study. The completed sample included 815 Asian Americans which included Cambodians (N=215), Vietnamese (N=195), Koreans (N=94) and Chinese (N=311). A 95-item questionnaire was developed and pilot tested for content validity and reliability. An in-person data collection approach was utilized and participants were given choice in responding in English or their native language. Of the 815 participants, 79.1% (N=645) reported never-screened, 7.9% (N=64), non-compliance, and 13.0% (N=106) compliance. Education was significantly associated with never-screened for CRC for Vietnamese and Chinese; employment status for Cambodians and Koreans; lack of health insurance for Cambodians, Korean and Chinese; English fluency and years lived in the U.S. for Vietnamese, Koreans, and Chinese. Less acculturated Asian Americans were more likely to be never screened, but differentially across ethnic subgroups. Barriers to screening included lack of knowledge, language, transportation, and time. Increased culturally-targeted public awareness and education programs are needed to improve CRC screening and compliance among high risk Asian American ethnic subgroups.

Colorectal cancer screening disparities in Asian Americans and Pacific Islanders: which groups are most vulnerable?

BACKGROUND

Colorectal cancer (CRC) is a significant cause of mortality among Asian Americans and Pacific Islanders (AAPIs), yet studies have consistently reported lower CRC screening rates among AAPIs than among non-Latino Whites and African Americans. Moreover, existing research tends to aggregate AAPIs as one group when reporting CRC screening, masking the disproportionate burden in cancer screening that exists across AAPI groups.

METHODS

This study examines differences in CRC screening rates in both aggregated and disaggregated AAPI groups as compared with non-Latino Whites in order to identify the most vulnerable AAPI subgroups in terms of obtaining CRC screening. This study utilizes merged data from the 2001, 2003, and 2005 California Health Interview Survey (CHIS), specifically the data pertaining to adults aged 50 and older (n = 52,491) from seven AAPI groups (Chinese, Japanese, Korean, Filipino, South Asian, Vietnamese, and Pacific Islander) and non-Latino Whites. Andersen's Behavioral Model of Health Services Use was utilized to select potential confounders to racial/ethnic differences in CRC screening.

RESULTS

When AAPI groups were considered as an aggregate, their CRC screening rate (46.8%) was lower than that of non-Latino Whites (57.7%). When AAPI groups were disaggregated, further disparity was noted: Koreans (32.7%) showed the lowest CRC screening rate, whereas Japanese (59.8%) had the highest. When the influence of potential predisposing, enabling, and need confounders was adjusted, Koreans, Filipinos, and South Asians were found to have a lower likelihood than non-Latino Whites to undergo CRC screening. Comparisons among AAPI subgroups further revealed that Filipinos, Koreans, Pacific Islanders, and South Asians were less likely than Chinese, Japanese, and Vietnamese to receive CRC screening.

CONCLUSION

These results highlight the importance of identifying differences in CRC screening behavior among disaggregated AAPI subgroups in order to help health professionals and policy-makers prioritize which AAPI subgroups need the most urgent interventions in terms of CRC screening promotion.

The impact of cultural characteristics on colorectal cancer screening adherence among Filipinos in the United States: a pilot study

OBJECTIVES

Studies on colorectal cancer screening among specific Asian American groups are limited despite the fact that Asians are comprised of culturally distinct subgroups. The purpose of this study was to investigate the impact of cultural characteristics on colorectal cancer screening adherence among Filipinos in the United States.

METHODS

One hundred and seventeen Filipino men and women aged 50 years or older participated in the cross-section research design. Lifetime proportion of immigration, language preference and cultural beliefs of personal control regarding health outcomes measured cultural characteristics. Demographic and healthcare variables were also measured to describe the study sample. Participant recruitment employed culturally responsive sampling methods.

RESULTS

There was no significant association between language preference and screening. Likewise, perceived personal internal control of health outcome was not related to screening. However, personal external control revealed a marginally significant association. The percent of lifetime residence in the United States was significantly greater among those who were adherent to screening than those who were not adherent. After adjusting for demographic and healthcare variables, the relationship between length of immigration and screening adherence was no longer significant. Finally, age and doctor's recommendation showed significant impact on colorectal cancer screening adherence.

DISCUSSION

This pilot study adds to the knowledge regarding cultural factors associated with colorectal cancer screening behaviors among Filipino Americans. Future research is needed to confirm findings that will be useful in developing culturally appropriate strategies to increase screening adherence.

Effective colorectal cancer education for Asian Americans: a Michigan program

Asian Americans are among the fastest growing population groups in the USA. Despite the fact that colorectal cancer (CRC) is the second most common cancer for this group, Asian Americans have low CRC screening rates. An established health promotion program, Healthy Asian Americans Project (HAAP), expanded to include community-based CRC education during 2005-2006. Using Asian-language media, HAAP promoted awareness throughout local Asian Indian, Chinese, Filipino, Hmong, Japanese, Korean, and Vietnamese American communities and recruited men and women over 50 years to attend health fairs at local community/cultural centers. Evaluation data from 304 participants in an evidence-based educational intervention showed significantly increased knowledge and attitudes about the importance of screening. Follow-up conducted between 6 and 12 months showed that 78% of those receiving the educational intervention had been screened in the last 12 months, compared with the 37% who had ever been screened with any of the tests prior to the study. This community-based health promotion program reached underserved populations and the educational intervention improved CRC screening rates. This and similar programs may help lower CRC mortality among Asian Americans.

Community-based colorectal cancer intervention in underserved Korean Americans

BACKGROUND

Despite evidence of a decline in both incidence and prevalence of colorectal cancer nationwide, it remains the second most commonly diagnosed cancer and the third highest cause of mortality among Asian Americans, including Korean Americans. This community-based and theoretically guided study evaluated a culturally appropriate intervention program that included a bilingual cancer educational program among Korean Americans including information on CRC risks, counseling to address psychosocial and access barriers, and patient navigation assistance.

METHODS

A two-group quasi-experimental design with baseline and post-intervention assessment and a 12-month follow-up on screening was used in the study. Korean Americans (N=167) were enrolled from six Korean churches. The intervention group received culturally appropriate intervention program addressing accessibility and psychosocial barriers, and navigation assistance for screening. The control group received general health education that included cancer-related health issues and screening.

RESULTS

There was a significant difference (p<0.05) between the post-intervention and control groups in awareness of CRC risk factors. There was also a significant improvement in the pre-post across HBM measures in the intervention group for perceived susceptibility (p<0.05) and benefits and barriers to screening (p<0.001). At baseline, 13% of participants in the intervention group and 10% in control group reported having had a CRC cancer screening test in the previous year. At the 12-month post-intervention follow-up, 77.4% of participants in the intervention group had obtained screening compared to 10.8% in the control group.

CONCLUSION

While health disparities result from numerous factors, a culturally appropriate and church-based intervention can be highly effective in increasing knowledge of and access to, and in reducing barriers to CRC screening among underserved Koreans.

Why are Korean American physicians reluctant to recommend colorectal cancer screening to Korean American patients? Exploratory interview findings

BACKGROUND

Korean Americans have one of the lowest screening rates for colorectal cancer. Although physician recommendation is one of the most important predictors of cancer screening across populations, only few Korean American patients receive such a recommendation.

METHODS

We interviewed 14 Korean American physicians in Los Angeles area who primarily serve Korean Americans to explore why they are reluctant to recommend colorectal cancer screening to their Korean patients.

RESULTS

Physicians identified barriers attributable to themselves (i.e., lack of knowledge, fear of medicolegal liability), their patients (i.e., patient's unfamiliarity with the concept of screening), and the health care system (i.e., lack of referral network, poor reimbursement).

DISCUSSION

Our results suggest the need for multi-faceted interventions directed at the physicians, their patients, and the health care system. Further research is needed to validate our results and to assess the extent to which they apply to physicians from other racial/ethnic groups.

Development of intervention materials for individuals with limited English proficiency: lessons learned from "Colorectal Cancer Screening in Chinese Americans"

BACKGROUND

According to recent US census data, 52 million people reported speaking a language other than English at home, and almost 45% of this population reported limited English proficiency (LEP). Colorectal cancer (CRC) ranks among the top 3 most common cancers for several Asian ethnic groups, yet screening remains underutilized by Asian Americans.

OBJECTIVES

This article describes the development of culturally and linguistically appropriate intervention materials for individuals with LEP. We discuss lessons learned from this research and implications for the translation of research into practice.

METHODS

The Health Behavior Framework served as the conceptual model for this study, and qualitative findings guided the development of our intervention materials (a video and pamphlet). To recommend Western preventive behaviors, the research team bridged the gap between Western and Chinese values and beliefs by devoting particular attention to: (1) the target population's sociocultural values and health beliefs; and (2) unique linguistic features of the Chinese language.

RESULTS

Key lessons learned from this study include the importance of: (1) a conceptual framework to guide intervention development; (2) incorporating sociocultural values and health beliefs into the intervention; (3) addressing and capitalizing on complex linguistics issues; (4) using qualitative methodology in cross-cultural research; and (5) contributions from a multicultural and multilingual research team. Other lessons relate to the translation of research findings into practice. We surmise that lessons learned from this study may be pertinent to the promotion of CRC screening among other patient groups with LEP and applicable to additional cancer screening tests.

Colorectal cancer screening among underserved Korean Americans in Los Angeles County

OBJECTIVES

Use of colorectal cancer screening is extremely low among Korean Americans. The objective of this study was to gather information on predictors, facilitators, barriers, and intervention preferences with respect to colorectal cancer screening that may inform the development of future interventions for underserved Korean Americans.

DESIGN

We developed a questionnaire guided by the Health Behavior Framework and administered it to a convenience sample of 151 Korean Americans aged 40-70 recruited through a community based organization in Los Angeles.

RESULTS

In our sample in which 60% of the subjects did not have health insurance, only 17% reported having received a stool blood test within the past year or sigmoidoscopy or colonoscopy within the past 5 years. Having received a physician recommendation was significantly associated and having symptoms of the disease was marginally associated with the outcome variable. Although 64% of respondents reported having a primary care physician, only 29% received a screening recommendation from a physician. Barriers to colorectal cancer screening were lack of health insurance and inability to afford testing, not knowing where to go for testing, language barrier, and fear of being a burden to the family. Intervention preferences included educational seminars, media campaigns, and print materials.

CONCLUSION

Our findings point to the need for a multi-faceted approach that includes educational seminars at community venues, a media campaign, and physician education to increase colorectal cancer screening in this underinsured Korean American population.

Correlates and predictors of colorectal cancer screening among male automotive workers

BACKGROUND

Most studies examining factors associated with colorectal cancer (CRC) screening (CRCS) are cross-sectional and thus temporal relationships cannot be determined. Furthermore, less attention has been paid to psychosocial predictors of CRCS. We examined both cross-sectional correlates of prior CRCS and predictors of prospective CRCS initiation and maintenance during The Next Step Trial, a 2-year worksite behavioral intervention to promote regular CRCS and dietary change.

METHOD

The sample included 2,693 White male automotive workers at increased occupational risk for, but no history of, CRC who completed a baseline survey. Stratified analyses were conducted for three dependent variables (prior CRCS, CRCS initiation, and CRCS maintenance). We also assessed prior CRCS as a moderator in prospective analyses. Multivariable logistic regression analyses with generalized linear mixed models were used to adjust for cluster sampling.

RESULTS

Except for education, cross-sectional correlates of prior CRCS including older age, family history of CRC or polyps, personal history of polyps, self-efficacy, family support, and intention were also significant prospective predictors of increased CRCS during the trial. Despite differences in the patterns of association for CRCS initiation and maintenance in stratified analyses, the only associations with prospective CRCS that were significantly moderated by prior CRCS were family history and CRCS availability.

CONCLUSIONS

Correlates of prior CRCS that also were prospective predictors of CRCS may be suitable targets for intervention. Additionally, intervention messages addressing psychosocial constructs may be relevant for both CRCS initiation and maintenance. However, studies with more diverse samples are needed to replicate the results reported here.

Promoting culturally appropriate colorectal cancer screening through a health educator: a randomized controlled trial

BACKGROUND

Colorectal cancer (CRC) is a leading cause of cancer mortality in the US. Surveys reveal low CRC screening levels among Asians in the US, including Chinese Americans.

METHODS

A randomized controlled trial was conducted with Chinese patients to evaluate a clinic-based, culturally and linguistically appropriate intervention promoting fecal occult blood test (FOBT) screening. The multifaceted intervention included a trilingual and bicultural health educator, bilingual materials (a video, a motivational pamphlet, an informational pamphlet, and FOBT instructions), and three FOBT cards. Patients in the control arm received usual care. Our primary outcome measure was FOBT screening within 6 months after randomization. The proportion of FOBT completion in the intervention and control arms was compared by using a chi-square test, and logistic regression analysis was performed to adjust for the effects of sociodemographic variables and prior screening history. Potential effect modifications were also tested by using logistic regression models.

RESULTS

Our intervention had a strong effect on FOBT completion (intervention group, 69.5%; control group, 27.6%), and the adjusted odds of FOBT slightly increased to over 6-fold greater in the intervention arm compared with the control arm. No effect modification by age, gender, language, insurance, or prior FOBT was found.

CONCLUSIONS

The authors' multifaceted, culturally appropriate intervention significantly increased FOBT screening in a group of low-income and less-acculturated minority patients. Given the large effect size, future research should determine the effective core component(s) that can increase CRC screening in both the general and minority populations.

Koreans' use of medical services in Seoul, Korea and California

This study assessed the types of health care services used by Korean immigrants, and differences in use between different countries, genders, health insurance status, acculturation status, and cardiovascular risk. Participant selection used probability sampling to represent the adult populations of California, United States, and Seoul, Republic of Korea. A telephone survey was administered to 2,830 adult Korean-Californians and 500 adult Koreans living in Seoul. Female gender was significantly associated with higher use of outpatient services, ER usage, and hospitalization. Californian residence was significantly associated with higher outpatient usage and lower hospitalization rates. Health insurance was associated with higher allopathic health care utilization, and lower traditional health care usage, and acculturation with lower traditional health care usage. Higher self-reported cardiac risk factors were associated with lower allopathic and higher traditional health care. This suggests barriers to allopathic health care, but not traditional health care, for Koreans living in California without health insurance.

Using focus groups to develop interventions to promote colorectal cancer screening among Vietnamese Americans

BACKGROUND

Colorectal cancer is the third most common cancer in Vietnamese Americans. Their colorectal screening rates are lower than the rates of whites.

METHODS

Four focus groups were conducted to identify Vietnamese American sources and credibility of health information, media utilization, and intervention approaches.

RESULTS

Vietnamese Americans trusted doctors and patient testimonials and had access to, and received most of their health information from, Vietnamese- language print and electronic media. Recommended intervention approaches include promoting doctors' recommendation of screening and using Vietnamese-language mass media, print materials, and oral presentations.

CONCLUSIONS

Focus groups are useful in determining communication channels and intervention approaches.

Disparities in colorectal cancer screening rates among Asian Americans and non-Latino whites

Among Asian Americans, colorectal cancer (CRC) is the second most commonly diagnosed cancer, and it is the third highest cause of cancer-related mortality. The 2001 California Health Interview Survey (CHIS 2001) was used to examine 1) CRC screening rates between different Asian-American ethnic groups compared with non-Latino whites and 2) factors related to CRC screening. The CHIS 2001 was a population-based telephone survey that was conducted in California. Responses about CRC screening were analyzed from 1771 Asian Americans age 50 years and older (Chinese, Filipino, South Asian, Japanese, Korean, and Vietnamese). The authors examined two CRC screening outcomes: individuals who ever had CRC screening and individuals who were up to date for CRC screening. For CRC screening, fecal occult blood test (FOBT), sigmoidoscopy/colonoscopy, and any other form of screening were examined. CRC screening of any kind was low in all populations, and Koreans had the lowest rate (49%). Multivariate analysis revealed that, compared with non-Latino whites, Koreans were less likely to undergo FOBT (odds ratio [OR], 0.40; 95% confidence interval [95% CI], 0.25-0.62), and Filipinos were the least likely to undergo sigmoidoscopy/colonoscopy (OR, 0.62; 95% CI, 0.44-0.88) or to be up to date with screening (OR, 0.68; 95% CI, 0.48-0.97). Asian Americans were less likely to undergo screening if they were older, male, less educated, recent immigrants, living with >or= 3 individuals, poor, or uninsured. Asian-American populations, especially Koreans and Filipinos, are under-screened for CRC. Outreach efforts could be more focused on helping Asian Americans to understand the importance of CRC screening, providing accurate information in different Asian languages. Other strategies for increasing CRC screening may include using a more family-centered approach and using qualified translators.
