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. Andersens 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.

Barriers to Cancer Screening in Hmong Americans: The Influence of Health Care Accessibility, Culture, and Cancer Literacy

Hmong Americans face high cancer mortality rates even in comparison to their Asian American counterparts, and report low utilization of cancer screenings. To date, no study has been conducted on the cultural barriers this population faces in undergoing cancer screenings. A systematic review of the literature was conducted to examine the existing knowledge regarding the barriers to cancer screening for Hmong Americans. Potential barriers were identified from this examination to include: health access factors (type of health insurance, ethnicity of provider, low English proficiency, and years spent in the U.S.); cultural factors (belief in the spiritual etiology of diseases, patriarchal values, modesty, and mistrust of the western medical system); and cancer literacy factors (cancer and prevention illiteracy). Based on this review, potential cultural and ethnic group-specific prevention strategies and cancer health policies are discussed to address these barriers and enhance screening behavior among the Hmong.

Breast and Cervical Cancer Screening Disparity Among Asian American Women: Does Race/Ethnicity Matter?

BACKGROUND Ethnic minorities are frequently considered as one homogeneous group in research, and this trend is particularly true for Asian Americans. This article seeks to uncover the intragroup differences in cancer screening behavior among subgroups of Asian American women by disaggregating them into six subgroups. The subgroups were compared with non-Latina white women to examine differences in breast and cancer screening rates and relevant factors associated with receiving these screenings. METHODS Three-year merged data from the 2001, 2003, and 2005 California Health Interview Survey (CHIS) were used to investigate the subgroup differences. Samples for the current study were restricted to non-Latina white and Asian American women whose age was ≥ 18 years (n = 58,000) for cervical cancer screening and ≥ 40 years (n = 43,518) for breast cancer screening at the time of the interview. RESULTS Results showed marked differences in cancer screening rates among Asian American subgroups and between cancer types. Cervical cancer screening rates were noticeably higher than breast cancer screening rates in all groups. The Korean group consistently showed the lowest rates of both cancer screenings. Japanese ranked the highest (79.5%) in breast cancer screening but the second lowest (79.7%) in cervical cancer screening. Enabling factors, such as having private health insurance and a usual source of care, were found to be the strongest predictors of receiving both breast and cervical cancer screening. Screenings for both types of cancer increased if a woman was married or was born in the United States. CONCLUSIONS The findings of this study illustrate the heterogeneity that exists among Asian American subgroups in their cancer screening behaviors. Further development of culturally relevant and ethnic-specific cancer prevention strategies and policies that address the subgroup differences within the larger racial/ethnic population are needed. Public health outreach and cancer education should be prioritized to the Asian American women who are more recent arrivals in the United States and have minimal access to healthcare.

Breast cancer screening behaviors among Korean American immigrant women: findings from the Health Belief Model.

This study examined the utilization of clinical breast examinations (CBEs) and mammograms among Korean American immigrant women and investigated how the six constructs of Health Belief Model (HBM) are associated with the receipt of breast cancer screening. Using a quota sampling strategy, 202 Korean American immigrant women were recruited in metropolitan areas in the northeastern United States. Approximately 64% of the participants reported having had at least one CBE in their lifetime, and about 81% of the sample had undergone at least one mammogram in their lifetime. Women who perceived themselves to be susceptible to breast cancer were more likely to have undergone a CBE, and women who had lower barriers to screening or demonstrated a higher level of confidence were more likely than their counterparts to undergo a mammogram. Findings suggest that HBM constructs such as susceptibility, barriers, and confidence should be considered when designing interventions aimed at promoting breast cancer screening.

Disparities in Human Papillomavirus Vaccine Literacy and Vaccine Completion Among Asian American Pacific Islander Undergraduates: Implications for Cancer Health Equity

Abstract Purpose: Low rates of human papillomavirus (HPV) vaccination among young Asian American and Pacific Islander (AAPI) women need to be addressed, particularly given the high incidence of cervical cancer in this population. The current study aims to investigate predictors of HPV vaccination in young AAPI and non-Latina white (NLW) women. Methods: A secondary data analysis was conducted of a health survey administered to college-aged women (N = 2,270) at a large public university in the Midwest. Andersens behavioral model of health services utilization guided the study theoretically, and hierarchical logistic regression analysis was conducted to investigate research aim. Results: NLW women had a significantly higher rate of vaccine completion than AAPI women (NLW = 60.7%; AAPI = 38.6%). NLW women also scored higher on all 5 measures of HPV vaccine literacy than AAPI women. Both groups of undergraduate women reported that increasing age, knowledge about HPV, greater use of gynecological services, and knowing someone who had cancer were significant factors related to HPV vaccination completion. In the NLW group, fathers income was also found to be a predictor of HPV vaccination completion. Conclusions: Rate and predictors of HPV vaccination completion vary between NLW and AAPI women. Greater promotion of HPV literacy and gynecological service use should be made to young AAPI women to increase their HPV uptake. Further research should examine sociocultural factors that could hinder or promote HPV vaccination in young AAPI women.

Cervical cancer screening behavior among Hmong-American immigrant women.

OBJECTIVES To investigate Hmong-American immigrant womens utilization of cervical cancer screening, including the impact of cultural health beliefs on screening use. METHODS Overall, 164 Hmong-American immigrant women 21 to 65 years of age were recruited from a large metropolitan area in the Midwest. We used logistic regression, guided by Andersens Behavior Model, to examine factors associated with the receipt of Pap test. RESULTS About 67.1% had received a Pap test within the last 3 years. Fatalism, modesty, education, and marital status were significantly correlated with receiving a Pap test. CONCLUSION The provision of cervical cancer literacy education and related preventive guidelines to this population are urgently needed to reduce cancer-screening disparity.

MHealth pilot study: Text messaging intervention to promote HPV vaccination

OBJECTIVES To test the feasibility and efficacy of a culturally-tailored mobile health intervention designed to increase knowledge about, intent to obtain, and receipt of the HPV vaccine. METHODS A 7-day text message HPV intervention was developed using a quasi-experimental research design for 30 Korean-American women. RESULTS Participants demonstrated significant increases in knowledge of HPV with an intent to get vaccinated within one year, and 30% of participants received the first dose of the HPV vaccine. CONCLUSIONS Mobile health technology could be a promising tool in reducing the cancer burden for underserved populations.

Perception of Elder Mistreatment and Its Link to Help-Seeking Intention: A Comparison of Elderly Korean and Korean American Immigrants

The study examined perceptions of elder mistreatment (EM) and help-seeking intentions in two older Korean cohorts—residents in Korea (n = 124) and Korean immigrants (n = 124) in the United States, recruited using a quota sampling strategy. A mixed method survey utilized four hypothetical scenarios of physical, financial, and psychological abuse and neglect. A majority of participants perceived physical, financial, and psychological abuse scenarios as EM but not the neglect scenario. Multivariate analysis showed strong association between perception of mistreatment and help-seeking intention in the Korea-based cohort for all types of EM. In the immigrant cohort, help-seeking intention was associated with only the physical abuse vignette. The results suggest a need for culturally sensitive, type-specific EM interventions and education and policies on elder neglect in both countries.

Technology Access and Use, and Their Associations With Social Engagement Among Older Adults: Do Women and Men Differ?

Objectives To examine how information and communication technology (ICT) access and use are conceptually incorporated in the Successful Aging 2.0 framework. Method Using data from the 2011 National Health and Aging Trends Study (N = 6,476), we examined how ICT access and use for different purposes are associated with social engagement (i.e., informal and formal social participation) by gender. Weighted logistic regression analyses were performed. Results Findings revealed that men were more likely to access and use ICT than women. ICT access was positively associated with all types of womens social engagement, but only with mens informal social participation. Information technology (IT) use for health matters was positively associated with formal social participation for women and with informal social participation for men. IT use for personal tasks was negatively associated with formal social participation for older adults. Communication technology use was positively associated with formal and informal social participation for women and men. Discussion This study supports the expansion of the successful aging model by incorporating ICT access and use. Further, it assists in the identification of specific technologies that promote active engagement in later life for women and men.
