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

Breast Cancer Screening among African Immigrants in the United States: An Integrative Review of Barriers, Facilitators, and Interventions

The purpose of this review was to synthesize the available literature on breast cancer-screening barriers, facilitators, and interventions among U.S. African immigrants. Following the integrative review framework and PRISMA guidelines for reporting systemic reviews, five electronic databases were searched: PubMed, CINAHL, PsycINFO, Medline, and Google Scholar. Studies were included if they were published in English language journals after 1 January 2000 and reported data on breast cancer-screening barriers, facilitators, or interventions among U.S. African immigrants. Barriers and facilitators reported by studies were descriptively examined and synthesized by two authors and classified as aligning with one of the three levels of influences based on the social-ecological model (intrapersonal, interpersonal, and community). Interventions promoting breast cancer screening were narratively summarized. Search procedures retrieved 1011 articles, with 12 meeting the criteria for inclusion in the review (6 qualitative and 6 quantitative). Intrapersonal barriers included limited awareness, fear of pain, language barriers, health concerns, transportation issues, costs, and negative past experiences. Interpersonal barriers involved modesty, spiritual beliefs, and lack of support, while community-level barriers included provider and healthcare-system challenges. Regarding facilitators, past screening experiences and health insurance were the most commonly reported intrapersonal facilitators. The only interpersonal facilitator identified was observing other women experience a breast cancer diagnosis and undergo treatment. Community-level facilitators included appointment reminders, scheduling assistance, culturally congruent interpreters, transportation to screening facilities, and patient navigators. Three articles reported outcomes of breast cancer-screening interventions. All three were pilot studies and reported increased knowledge and attitudes regarding breast cancer screening following the respective interventions. One study examined the uptake of breast cancer screening following the intervention, with results indicating an increase in screening. Findings provide a comprehensive synthesis of factors influencing breast cancer screening among African immigrants and highlight the need for future research on the topic. This review was registered with Prospero (CRD42024502826) before the initiation of search procedures.

Factors affecting cancer screening perception in Turkish women: the role of health literacy

It is suggested that individuals with limited health literacy have less awareness about cancer and screening methods. However, there is a paucity of evidence regarding the relationship between cancer screening perception and health literacy levels among women. This study investigates the determinants of cancer screening perceptions in Turkish women, with a particular emphasis on the influence of health literacy. Employing a cross-sectional design, the study involved 428 women aged 18-69. Data were collected via online questionnaires. Hierarchical regression analysis was utilized to assess the effects of distinct variables on cancer screening perceptions. Exploratory and confirmatory factor analyses were employed to validate and ensure reliability. The results indicated that the constructed hierarchical regression model explicated around 10% of the variance in cancer screening perceptions. Among the various factors examined, health literacy emerged as the most potent predictor of screening perceptions. Individuals possessing higher health literacy demonstrated more favorable attitudes toward cancer screening. Additionally, age surfaced as another notable determinant, with advanced age correlating positively with awareness and receptiveness to screening. This research reveals the pivotal role of health literacy in shaping how Turkish women perceive cancer screening. While a few factors have an impact, the study highlights the urgent need to elevate health literacy levels to foster heightened awareness and engagement in cancer screening programs. The study's findings offer valuable guidance for devising targeted interventions to address disparities in cancer screening perception and participation, particularly among women in low- to middle-income countries such as Turkey.

Patient-Physician Relationships and Mammography Use in Korean American Women

Breast cancer is prevalent and fatal in Korean American women (KAW) and KAW report low screening rates. This study examined the impact of patient-physician relationships on mammography use in KAW, focusing on patient-physician ethnic and gender concordance, distrust in health professionals, and accessibility to health care. Cross-sectional survey data were collected from 340 KAW in North Carolina, and logistic regression was conducted to identify factors associated with mammography use. Having a non-Korean physician, regular check-ups, and physician recommendations were positively associated with getting mammography. Neither gender concordance nor distrust in health professionals predicted adherence to breast cancer screening guidelines. The findings highlight the critical roles of routine health care practice and usual source of care in compliance with the screening guidelines in KAW. Additional research is warranted to explore breast cancer screening recommendation behaviors and patterns of Korean American physicians compared to non-Korean counterparts.

Knowledge and Factors Associated with Breast Cancer Self-Screening Intention among Saudi Female College Students: Utilization of the Health Belief Model

Breast cancer (BC) screening is vital, as it is linked to a greater likelihood of survival, more effective treatment, and better quality of life. One of the most extensively applied models for conceptualizing probable barriers and facilitators to the adoption of desired health behavior is the health belief model (HBM). This study aimed to assess the impact of health perception and knowledge on breast self-examination intention (BSE) using HBM. HBM measures specific factors (perceived susceptibility, severity, barriers, benefits, cues to action, and self-efficacy) that impact one's intention to use BSE. Data were collected from female undergraduate students (n = 680) using a cross-sectional design, stratified simple random sampling, and a self-administered structured online questionnaire. We used multivariable logistic regression to evaluate our assumptions for students who intended to self-examine for BC. For demographic factors, we modified the multivariate model. Most respondents (93%) were under the age of 24 years. Female students from health colleges (48.5%), in their fourth academic year (42.6%), and from the southern region (57.6%) accounted for the majority of the sample. Respondents with a family history of BC were 9.7% of the total. Categories for age, college, region, residency, and BSE intention showed significant differences in their average knowledge scores. The survey revealed that 72.4% were aware of abnormal breast changes. Three constructs of the health belief model (perceived benefit, perceived barriers, and self-efficacy) are good predictors of BSE intention. Theory-based behavioral change interventions are urgently required for students to improve their prevention practices. Furthermore, these interventions will be effective if they are designed to remove barriers to BSE intention, improve female students' self-efficacy, and enlighten them on the benefits of self-examination.

Factors linked to accessing COVID-19 recommendations among working migrants

Objectives

Guided by the Health Belief Model (HBM), this study explored factors associated with accessing COVID‐19 health information.

Design/sample

A cross‐sectional study design was used.

Sample

Migrants (n = 259) employed in Israel prior to the onset of the COVID‐19 pandemic were recruited.

Measurements

The on‐line questionnaire included: The Satisfaction with Life Scale, the Brief Resilience Coping Scale and Immigrants' Language Ability scale.

Results

Migrants obtaining COVID‐19 information when issued were more likely to have decreased employment or unemployment after COVID‐19 government restrictions (OR = 1.98; CI = 1.03, 3.89; p < .05) and more likely to have a better language ability (OR = 1.20; CI = 1.10, 1.32, p < .0001), but they were less likely to use family and/or friends as their COVID‐19 health resource (OR = 0.54, CI = 0.30, 0.96; p < .05). Migrants encountering the most employment difficulties were: female (p < .05), older age (p < .05), unmarried (p < .01), with unstable finances (p < .0001), and in Israel less than 5 years (p < .01).

Conclusions

Migrants with more precarious employment had more societal disadvantage (i.e., women, older age, unmarried, poorer socioeconomic status, and newer migrants) and relied on informal and potentially inaccurate, health sources. Public health officials aiming to decrease COVID‐19 infection must improve health information access to all members of society, particularly at‐risk groups such as migrants.

The Association Between Fatalism and Mammography Use in Korean American Immigrant Women

Fatalism is reported as a salient cultural belief that influences cancer screening disparities in racial and ethnic minority groups. Previous studies provide a range of measures and descriptions of cancer fatalism, but no studies to our knowledge have analyzed how fatalistic views cluster together within subgroups to form distinct profiles, and how these profiles can be predicted. This study identified subgroups of Korean American immigrants with similar fatalistic beliefs toward cancer and examined the influence of fatalism, health belief variables, and health literacy on mammography use. A cross-sectional survey design was used to obtain a convenience sample of 240 Korean American immigrant women in Los Angeles, California. Latent class analysis was used to identify unobserved subgroups of fatalism. Hierarchical logistic regression models were used to identify predisposing, enabling, and need factors associated with recent mammography use. The latent class analysis model identified three cancer fatalism subgroups: high fatalism (17.8%), moderate fatalism (36.7%), and low fatalism (45.5%). Women in the high fatalism subgroup were more likely to have had a mammogram within the past 2 years than women in the low fatalism subgroup. Regression analysis revealed three facilitators of recent mammogram use: level of fatalism, perceived barriers to mammogram, and family history of cancer. Although cultural beliefs can have a powerful influence on health-seeking behavior, it is important to weigh individual and contextual factors that may weaken or mediate the relationship between fatalism and engaging in preventive care such as having a mammogram.

Analyzing factors associated with decisional stage of adopting breast cancer screening among Korean American women using precaution adoption process model

Background: Korean American (KA) women have experienced higher prevalence and lower survival rates of breast cancer (BC) than other ethnic groups in the United States. However, BC screening rates for KA women remain significantly lower than the national target (81.1%) specified by Healthy People 2020. Few studies have explained how the decision to adopt BC screening occurs and progresses and what factors contribute to this decision among KA women. This study used Weinstein's Precaution Adoption Process Model (PAPM) as a theoretical framework to examine characteristics and factors associated with the decisional stage of mammography adoption.Methods: A cross-sectional self-report survey was administered among KA women (N = 308) ages 50-80 from the Atlanta metropolitan area. A total of 281 KA women completed the survey, answering questions about socio-demographics, health-related information, mammography history, doctor recommendation, BC screening knowledge, self-efficacy for BC screening, decisional balance scores on attitudes and beliefs pertaining to mammography, and the seven-stage PAPM.Results: KA women reported a low rate of mammography uptake with about 24% and 35% of the participants undergoing mammography within the last year and two years, respectively. KA women in stages 5 (decided yes), 6 (action), and 7 (maintenance) were likely to have increased screening-related knowledge, positive decisional balance, and regular medical check-up compared to those in stages 1 (unaware), 2 (unengaged), and 3 (deciding).Conclusion: This study highlights important factors that could potentially facilitate BC screening among KA women in Georgia. The findings also provide implications for interventions and practice for increasing mammography screening among medically underserved populations.

Culturally Tailored Intervention to Promote Mammography Screening Practice Among Chinese American Women: a Systematic Review

Our review aimed to assess the effectiveness of culturally tailored intervention in mammography practice for Chinese American women. We searched the entire paper published by the Cochrane Library, PubMed, and Web of Science from inception to 17 October 2019. Moreover, we manually checked reference lists of included studies to find other potentially eligible studies. It included clinical trials published in English that evaluated the effects of culturally tailored intervention on mammography practice for Chinese American women. Finally, we involved eight studies in our review. After the intervention, the mammography intention and breast cancer-related knowledge were significantly improved. However, there was no significant impact on mammography completion rate, perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers, and Eastern cultural views of Chinese American women. The culturally tailored interventions could serve as promising approaches to improve mammography screening practice for Chinese American women, but further improvements are needed.

Association of depression with adherence to breast cancer screening among women aged 50 to 74 years in the United States

RATIONALE, AIMS, AND OBJECTIVES

Previous research has shown inconsistent results regarding the association of depression and screening mammography use behaviours. This study aimed to assess the relationship between women's depression and mammography adherence.

METHODS

This cross-sectional study used data from the 2016 Behavioural Risk Factor Surveillance System and employed the Health Belief Model (HBM). The primary independent variable was the presence of depression. The dependent variable was adherence to biennial screening mammography based on the US Preventive Services Task Force guidelines. Demographic characteristics and HBM constructs were included as covariates. Univariate and multivariate logistic regressions were used.

RESULTS

A total of 139 550 women were included (weighted n = 48 712 531). Among them, 23.1% reported the presence of depression (n = 32 247). The unadjusted odds ratio (OR) for mammography use in women with depression was 0.85 (95% confidence interval [CI], 0.80-0.91, P < .001) compared with women without depression, and the probability of mammography use was significantly lower in women with depression (76.3%; 95% CI, 75.4-77.3) compared with women without depression (79.1%; 95% CI, 78.5-79.6). However, the adjusted OR was not statistically significant when controlling for demographic and HBM characteristics (1.02; 95% CI, 0.93-1.11, P = .698), and the probabilities of mammography use were similar between women with depression (80.1%; 95% CI, 79.0-81.3) and without depression (79.9%; 95% CI, 79.2-80.6).

CONCLUSIONS

Depression itself was related to nonadherence with mammography screening guidelines. However, after controlling for demographic and HBM characteristics, depression was not associated with adherence with mammography screening guidelines.

Older Women’s Perspectives Driving Mammography Screening Use and Overuse: a Narrative Review of Mixed-Methods Studies

Purpose of Review

Examining what older women know and perceive about mammography screening is critical for understanding patterns of under- and overuse, and concordance with screening mammography guidelines in the USA. This narrative review synthesizes qualitative and quantitative evidence around older women’s perspectives toward mammography screening.

Recent Findings

The majority of 43 identified studies focused on promoting mammography screening in women of different ages, with only four studies focusing on the overuse of mammography in women ≥ 70 years old. Older women hold positive attitudes around screening, perceive breast cancer as serious, believe the benefits outweigh the barriers, and are worried about undergoing treatment if diagnosed. Older women have limited knowledge of screening guidelines and potential harms of screening.

Summary

Efforts to address inequities in mammography access and underuse need to be supplemented by epidemiologic and interventional studies using mixed-methods approaches to improve awareness of benefits and harms of mammography screening in older racially and ethnically diverse women. As uncertainty around how best to approach mammography screening in older women remains, understanding women’s perspectives along with healthcare provider and system-level factors is critical for ensuring appropriate and equitable mammography screening use in older women.

Breast Cancer Screening Behaviors in Women Aged 40 Years and Over in a Semi-Urban Region in Turkey: Relationships with Health Beliefs

In this study, we aimed to determine the breast cancer screening behavior of women and to investigate the relationship between health beliefs and screening behaviors. The study was cross-sectional. It was conducted between April 2017 and June 2017 with 416 women aged ≥40. The Sociodemographic Information Form and the Champion's Health Belief Model Scale were used to collect data. In the statistical analysis, the number, percentage, mean, standard deviation, Pearson chi-square test, and multivariate binary logistic regression analysis were used. The rates for participating women performing breast self-examination, having clinical breast examination, and undergoing mammography were 11.8%, 8.9%, and 11.3%, respectively. Perceived susceptibility, seriousness, self-efficacy, benefits, health motivation, and perceived barriers were found to have strong associations with screening behaviors (p < 0.05). In this study, we found that few women performed breast self-examination, had clinical breast examination and mammography. In the present study, women perceived barriers related to both performing breast self-examination and undergoing mammography.

Barriers and Facilitators to Breast and Cervical Cancer Screening Among Immigrants in the United States

To summarize the literature on barriers and facilitators to breast and cervical cancer screening among immigrants to the US. A literature review was conducted for studies on breast and cervical cancer screening among immigrant populations. A thematic analysis of 180 studies identified a variety of barriers and facilitators to screening at the personal and system levels. Personal barriers included lack of knowledge and insurance coverage, high cost of care, and immigration status. System barriers included poor access to services, lack of interpreter services, and insensitivity to patient needs. Facilitators to screening included knowledge of disease, access to information sources, physician recommendation, and social networks. Cultural norms and resource availability at the individual and system levels influence screening among immigrants. Health insurance coverage was found to be an important predictor of preventative screening use. Future research should seek to identify the best way to address this and other barriers to cancer screening among immigrants groups.

Effectiveness of a health belief model intervention using a lay health advisor strategy on mouth self-examination and cancer screening in remote aboriginal communities: A randomized controlled trial

OBJECTIVE

Oral cancers caused by chewing betel nuts have a poor prognosis. Using a lay health advisor (LHA) can increase access to health care among underprivileged populations. This study evaluated a health belief model (HBM) intervention using LHAs for oral cancer screening (OCS) and mouth self-examination (MSE) in remote aboriginal communities.

METHODS

The participants were randomly assigned to intervention (IG; n = 171) and control groups (CG; n = 176). In the IG, participants received a three-chapter one-on-one teaching course from LHAs, whereas those in the CG received only a leaflet.

RESULTS

The IG participants were 2.04 times more likely to conduct a monthly MSE than those in the CG (95% confidence interval: 1.31-3.17) and showed significantly higher self-efficacy levels toward OSC and MSE (β = 0.53 and 0.44, effect size = 0.33 and 0.25, respectively) and a lower barrier level for OSC (β = -1.81, effect size = -0.24).

CONCLUSION

The LHA intervention had a significantly positive effect on MSE, strengthening self-efficacy and reducing barriers to OCS among aboriginal populations.

PRACTICE IMPLICATIONS

The effectiveness of the clinical treatment of underprivileged group can be improved through early diagnosis, which can be achieved using LHAs to reduce barriers to OSC.

Predictors of never having a mammogram among Chinese, Vietnamese, and Korean immigrant women in the U.S

BACKGROUND

Breast cancer is the most common cancer among Asian women in the U.S. The first objective was to investigate predictors (including ethnicity) of never having a mammogram in middle-aged and older Chinese, Vietnamese, and Korean immigrant women (main effects). The second objective was to explore whether relationships between predictors and never having a mammogram varied across the three groups (moderation effects of ethnicity).

METHODS

Merged (2005-2007-2009-2011) California Health Interview Survey data were utilized. Unweighted sample was 3,710 Asian women ages 40 years and older (Chinese = 1,389; Vietnamese = 1,094; Korean = 1,227). Replicate weighted total sample size was 1,710,233 (Chinese = 940,000; Vietnamese = 410,000; Korean = 360,000). Replicate-weighted multivariate logistic regression was applied. Interaction effects (moderator role of ethnicity) were also examined, using multivariate logistic regression, for the second objective.

RESULTS

For the first objective, odds of never having a mammogram were higher for women who were Korean (Ref = Vietnamese), unmarried, or a non-U.S. citizen. Odds were lower in women ages 50-59 or 60-69 (Ref = 70-85). Regarding the second objective, only for Chinese women, odds of never having a mammogram were lower as the number of physician visits got higher.

CONCLUSION

Culturally-sensitive outreach and services should be developed to target higher-risk groups. Patient-centered healthcare strategies tailored for the three groups could be effective. For Chinese women, in particular, regular information sessions or education programs could be provided for enhancing their physician visits.

Barriers to Breast Cancer Screening and Coping Strategies in Korean American Women

Introduction: To develop more culturally appropriate and effective intervention strategies, this qualitative study explored Korean American women's barriers to mammography and their coping strategies within their sociocultural context. Methodology: Semistructured individual interviews were conducted with 30 Korean American women in 2016. Thematic analysis was used to analyze the data and identify themes. Results: Four themes and their associated subthemes emerged from the data: (1) barriers to accessing mammography (cost, time consuming and complicated procedure, and language barriers), (2) psychosocial concerns related to mammography (pain, discomfort and embarrassment, and exposure to radiation), (3) strategies to access mammography (identifying ways to get a cost-free mammogram and having procedure done in home country), and (4) ways to deal with psychosocial concerns (being positive and avoiding or postponing the procedures). Discussion: Health professionals should account for cultural differences including, but not limited to, patients' concerns, access to care, and beliefs surrounding screening processes.

Analyzing factors enabling colorectal cancer screening adherence in Korean Americans using the Andersen's Behavioral Model of Health Services Utilization

Purpose/objectives: Korean Americans (KAs) report suboptimal colorectal cancer (CRC) screening adherence. This study investigated factors that enable KAs to adhere to CRC screening guidelines using the Andersen's Behavioral Model of Health Services Utilization. Design: Cross-sectional survey using self-reported measures of CRC screening behaviors. Sample and methods: Purposive sampling was used to recruit 433 KAs aged 50-75 from the Atlanta metropolitan area who completed questionnaires measuring predisposing (i.e., gender, age, marital status, and educational attainment), enabling (income, health insurance, regular annual health checkups, doctor's recommendation English proficiency, CRC knowledge, self-efficacy for CRC screening, and decisional balance in CRC screening), and need (family cancer history and self-reported health status) factors associated with CRC screening. Findings: A multiple logistic regression model including all 14 predictor variables revealed that several enabling factors (i.e., income, regular annual health checkups, doctor's recommendation, self-efficacy, and decisional balance) independently predicted increased CRC screening adherence in KAs. No predisposing or need factors independently predicted CRC screening. Conclusions and implications for psychosocial providers or policy: To increase CRC screening adherence among KAs, psychosocial interventions should target on improving their self-efficacy and decisional balance regarding CRC screening, while policy interventions should focus on promoting health providers' CRC screening recommendations during routine health checkups.

Development and Validation of the Dietary Habits and Colon Cancer Beliefs Survey (DHCCBS): An Instrument Assessing Health Beliefs Related to Red Meat and Green Leafy Vegetable Consumption

Dietary patterns characterized by higher red meat (RM) consumption are associated with increased colon cancer (CC) risk. Preclinical and epidemiological evidence suggest higher green leafy vegetable (GLV) consumption may mitigate these risks. Determining the relationship between dietary habits and expected health outcomes is needed. Methods. The Health Belief Model (HBM) was used to assess perceived CC susceptibility and severity, and related dietary benefits, barriers, and motivators. RM and GLV consumption were quantified using select DHQII items (n=15) capturing the previous 30 days' intake. A 34-item Qualtrics survey was provided to a convenience sample of 1,075 adults residing throughout the US Confirmatory factor analysis measured fitness with HBM, and Cronbach's alpha assessed subscale reliability. A subsample (n=47) completed a 2-week follow-up for test-retest reliability. Independent sample t-tests were used to compare RM and GLV intake and DHCCBS responses between genders. Individual barrier questions and RM and GLV consumption were compared using ANOVA for each gender; post hoc analyses between barrier question responses were assessed with Bonferroni correction. Results were considered significant with a p value of less than 0.05. Results. 990 US adults (52.7% female, 79.1% white, 50.8% aged 35+ years) completed valid surveys. Factor analysis with varimax rotation validated the construct of HBM subscales; only one question had a loading less than 0.745. Subscale Cronbach's alphas ranged within 0.478-0.845. Overall test-retest reliability was acceptable (r=0.697, p=5.22x10⁻⁸). Participant BMI was (mean±SD) 26.7±6.6 kg/m². Participants consumed (median, IQR) 2.3, 0.9-4.7 cooked cup equivalents GLV/week and 12.2, 5.8-21.5 ounces RM/week. Over half of respondents agreed or strongly agreed with the statement “I can't imagine never eating red meat,” while less than one eighth of respondents agreed or strongly agreed with the statement “I don't like the taste of green leafy vegetables.” Conclusion. The DHCCBS is a valid instrument for measuring health beliefs related to red meat, green leafy vegetables, and perceived colon cancer risk. Additionally, these findings suggest increasing GLV may be more feasible than reducing RM for CC risk reduction in meat eaters.

A patient-centered mobile health application to motivate use of genetic counseling among women with ovarian cancer: A pilot randomized controlled trial

OBJECTIVE

Despite current guidelines recommending women with ovarian cancer receive genetic risk evaluation by a genetic counselor, utilization has historically been low. We sought to assess the feasibility and effectiveness of a week-long mobile Application for Genetic Information on Cancer (mAGIC) intervention aimed to persuade women with ovarian cancer to pursue genetic counseling.

METHODS

The mobile application intervention was based on the Fogg Behavior Model, and consisted of three parts: (1) identifying barriers, (2) developing motivators, and (3) providing triggers to action. The Health Belief Model was used to guide content development. We conducted a prospective, randomized, controlled pilot trial among 104 untested women with a history of epithelial ovarian, primary peritoneal or fallopian tube cancer with the primary objective of increasing uptake of cancer genetic counseling services.

RESULTS

Utilization of cancer genetic counseling services improved in both study arms over historical controls, however there was no statistically significant difference between them (intervention: 54.5% versus control: 38.6%; p = 0.14). However, compared to controls, women randomized to the mAGIC intervention demonstrated greater knowledge of hereditary cancer (0-10 scale; 9.4 ± 1.0 vs. 7.1 ± 1.5; p < 0.0001), which persisted for at least three months. Additionally, 96% of women in the intervention group reported they had talked with their family about genetic counseling compared to 77% in the control group (p = 0.01).

CONCLUSIONS

The mAGIC intervention did not result in increased uptake of genetic counseling, however it provided significant secondary benefits, including increased participants' knowledge about hereditary ovarian cancer, self-efficacy, and their reported communication with family members. ClinicalTrials.gov Identifier: NCT02877862.

Factors Associated with Breast Cancer Screening among Korean American Women in California: Results from the California Health Interview Survey 2015–2016

Background: Few studies have examined preventive lifestyle behaviors and breast cancer (BC) screening behaviors simultaneously to determine whether BC screening behaviors are associated with preventive lifestyle behaviors. The purposes of this study are to (a) describe BC screening utilization and preventive lifestyle behaviors and (b) examine factors associated with BC utilization among Korean American (KA) women. Methods: Data from the 2015–2016 California Health Interview Survey were analyzed. Survey-weighted adjusted logistic regressions were used to determine whether preventive lifestyle behaviors and characteristics of KA women 50 years of age and older at the time of the survey were associated with obtaining mammograms. Results: Most participants were born outside of the US and had lived in the US for 15 years or more at the time of the survey. This study found that KA women who were 50–64 years old had 38 times greater odds of having ever had a mammogram and a 13 times greater odds of having a recent mammogram than those 65 and older. KA women who walked at least 10 minutes per week for transportation and leisure purposed were 61 times more likely to have ever had a mammogram than those who did not walk. Conclusion: This study provides important perspectives on associations of BC screening behaviors and preventive life-style behaviors, especially walking. Future research should be conducted to better understand the association between BC screening and preventive life-style behaviors and to develop feasible interventions to improve BC screening behaviors among KA women, particularly elderly and physically inactive ones.

Breast cancer literacy and health beliefs related to breast cancer screening among American Indian women

The purpose of this article is to examine the health beliefs and literacy about breast cancer and their relationship with breast cancer screening among American Indian (AI) women. Using the Health Belief Model (HBM) and hierarchical logistic regression with data from a sample of 286 AI female adults residing in the Northern Plains, we found that greater awareness of breast cancer screening was linked to breast cancer screening practices. However, perceived barriers, one of the HBM constructs, prevented such screening practices. This study suggested that culturally relevant HBM factors should be targeted when developing culturally sensitive breast cancer prevention efforts.

Applying the Health Belief Model and an Integrated Behavioral Model to Promote Breast Tissue Donation Among Asian Americans

An important part in the effort to prevent, treat, and cure breast cancer is research done with healthy breast tissue. The Susan G. Komen for the Cure Tissue Bank at Indiana University Simon Cancer Center (KTB) encourages women to donate a small amount of healthy breast tissue and then provides that tissue to researchers studying breast cancer. Although KTB has a large donor base, the volume of tissue samples from Asian women is low despite prior marketing efforts to encourage donation among this population. This study builds on prior work promoting breast cancer screenings among Asian women by applying constructs from the Health Belief Model (HBM) and the Integrated Behavioral Model (IBM) to investigate why Asian-American women are less inclined to donate their healthy breast tissue than non-Asian women and how this population may be motivated to donate in the future. A national online survey (N = 1,317) found Asian women had significantly lower perceived severity, some lower perceived benefits, and higher perceived barriers to tissue donation than non-Asian women under HBM and significantly lower injunctive norms supporting breast tissue donation, lower perceived behavioral control, and lower intentions to donate under IBM. This study also compares and discusses similarities and differences among East, Southeast, and South Asian women on these same constructs.

Factors affecting trust in healthcare among middle-aged to older Korean American women

Background

Predictors of trust in healthcare providers and the healthcare system have never been studied in Korean Americans (KA) despite the fact that trust plays an important role in health behaviors. The purpose of this study is to examine factors influencing trust in the healthcare system and providers among KA women.

Methods

Data were collected in 196 KA women examining the effects of perceived discrimination and trust on breast cancer screening in the Chicago metropolitan area. Path analysis was used to identify factors influencing trust in the healthcare system and providers.

Results

Acculturation was positively related to trust in healthcare providers (β = .15, p =. 002), and discrimination in the healthcare system was inversely related to trust in healthcare providers (β = −.60, p <. 001). Length of stay in the US was inversely related to distrust in the healthcare system (β = −.14, p <. 001), and discrimination in healthcare was positively related to distrust in the healthcare system (β = .60, p <. 001). Trust in healthcare providers and distrust in the healthcare system were moderately correlated (r = .51, p < .001).

Conclusion

Higher levels of acculturation and lower levels of perceived discrimination were identified as predictors of higher levels of trust in healthcare providers. A shorter stay in the US and higher levels of discrimination were identified as predictors of higher levels of distrust in the healthcare system. Perceived discrimination is a target for interventions to enhance trust in the healthcare system, and therefore reduce healthcare disparities in KAs.

Predictors of Breast Cancer Screening Among Korean American Women: Is Having an Annual Checkup Critical?

Objective: Korean American (KA) immigrant women underutilize breast cancer screening. This study examined factors predicting breast cancer screening behavior among KA women in the United States. Methods: 233 KA women aged 19 to 85 were recruited in the metro area of Atlanta, Georgia. Andersen’s behavioral model theoretically guided the study. Result: Of the predisposing factors, age (OR=1.043, p<.01, 95% CI [1.017, 1.069]) and marital status (OR=2.154, p<.05, 95% CI [1.022, 4.539]) were significantly associated with clinical breast exam (CBE), while income (OR=2.289, p<.05, 95% CI [1.060, 4.945]) and annual checkup (OR=2.725, p<.01, 95% CI [1.342, 5.533]) were linked to CBE as enabling factors. For the receipt of mammographic screening, annual checkup was only significantly associated among enabling factors (OR=4.509, p<.05, 95% CI [1.263, 16.102]), while family cancer history was identified as the only significant need factor (OR=.112, p<.01, 95% CI [.023, .552]). Conclusion: Differing factors explained the receipt of CBEs and mammographic use among KA women. Specifically, the findings shed light on the importance of having an annual checkup for the uptake of both CBEs and mammographic use. Intervention strategies should focus on promoting health accessibility for KA women to adhere to recommended breast cancer screening.

Knowledge and attitude of women regarding breast cancer screening tests in Eastern Iran

Introduction

According to recent statistics, there has been a rapid growth of breast cancer in developing countries. Thus, early detection is essential. This study is based on the perception of people in the Northeast of Iran regarding breast cancer screening.

Methods

In a cross-sectional study, 1469 women were selected randomly in the period from April to November 2016. The study population consisted of women or their companions referring to outpatient clinics or people in public urban areas who filled out a breast cancer screening questionnaire in an interview.

Results

The patients’ age was in the range of 14 to 84 years (mean = 38.8). More than 84% of interviewees were not informed of breast cancer and screening tests. The main reasons mentioned by patients for their failure to do screening tests was ‘absence of any symptom or problem’ and ‘they did not think it was necessary’.

There was not a significant difference between income level, marital status and knowledge of people about breast cancer screening tests (P > 0.05). However, employment, education level and family history had a positive effect on people’s awareness of breast cancer and its screening tests (P < 0.05).

Conclusion

The lack of knowledge in people from low socio-economic classes was the main barrier to breast cancer screening. In this regard, organizing training programs by physicians and the media can help raise screening rates.

Biomarker profiling for breast cancer detection: translational research to determine acceptance of a novel breast cancer screening technique

The current study seeks to determine how the psychosocial predictors of the health belief model are related to willingness to adopt biomarker screening practices among women above and below current screening age recommendations, as biomarker profiling can potentially detect cancer much earlier than current breast cancer detection methods. Patients (N = 205) at an Obstetrician/Gynaecology office in a mid-sized Midwest city. Participants completed a survey in the waiting room before their doctor appointment. Results revealed that benefits (p < .001), barriers (p = .02), cancer worry severity (p = .01), and self-efficacy (p = .002) were significant predictors of willingness to adopt biomarker profiling, and susceptibility was marginally related (p = .09). The direct effects are qualified by two interactions between psychosocial predictors of the health belief model and participants' age. The model predicted willingness to adopt biomarker screening well (R ² = 28%), and may be used successfully as a framework to assess the diffusion of biomarker screening acceptability.

Breast Cancer Screening Among Korean Americans: A Systematic Review

Cancer is the leading cause of death for Korean Americans (KAs). Breast cancer (BC) is the most commonly occurring cancer among KA women, and its rate has been rapidly increasing. Low BC screening rates for KAs puts them at greater risk for late-stage breast cancer. We conducted a systematic review of the published literature on cancer screening among KAs, and identified 38 eligible studies. Despite significant increases in mammogram utilization over the past two decades, KAs have consistently lower rates of mammogram screening than other American populations. KA women also report lower rates of clinical breast examination and breast self-examination. Screening rates are higher among adults with higher socioeconomic status, greater acculturation to the United States, more cancer knowledge, higher perceived susceptibility to BC, more social support, and better access to health services. However, fear of finding something wrong, fear of embarrassment or lack of modesty, not knowing where to go for screening, believing that mammography is only necessary when symptoms are present, and perceived time and cost difficulties in accessing mammography were reported as barriers to mammogram screening. Coordinated efforts from clinicians, public health workers, KA cultural and religious organizations, and the broader breast cancer advocacy and awareness community are necessary for improving BC screening among KAs.

Effects of Perceived Discrimination and Trust on Breast Cancer Screening among Korean American Women

OBJECTIVE

Korean American (KA) women continue to have lower breast cancer screening rates than other racial groups. Perceived discrimination and trust have been associated with breast cancer screening adherence, but little is known about the associations in KA women.

METHODS

Surveys were completed by 196 KA women in the Chicago metropolitan area. Multiple and Firth logistic regression analyses were performed to identify factors (perceived discrimination, trust, acculturation, cultural beliefs, health care access) influencing breast cancer screening adherence (mammogram). In addition, SPSS macro PROCESS was used to examine the mediating role of trust between perceived discrimination and breast cancer screening adherence.

RESULTS

Ninety-three percent of the women surveyed had health insurance and 54% reported having a mammogram in the past 2 years. Predictors of having a mammogram were knowing where to go for a mammogram, having a regular doctor or usual place for health care, greater trust in health care providers, and lower distrust in the health care system. Perceived discrimination had an indirect effect on breast cancer screening through trust.

CONCLUSIONS

The breast cancer screening rate among KA women is low. Perceived discrimination in health care, trust in health care providers, and distrust in the health care system directly or indirectly influenced breast cancer screening adherence in KA women. Trust is a factor that can be strengthened with educational interventions.

Mobile Phone Multilevel and Multimedia Messaging Intervention for Breast Cancer Screening: Pilot Randomized Controlled Trial

Background

Despite the increasing breast cancer incidence and mortality rates, Korean American immigrant women have one of the lowest rates of breast cancer screening across racial groups in the United States. Mobile health (mHealth), defined as the delivery of health care information or services through mobile communication devices, has been utilized to successfully improve a variety of health outcomes.

Objective

This study adapted the principles of mHealth to advance breast cancer prevention efforts among Korean American immigrant women, an underserved community.

Methods

Using a randomized controlled trial design, 120 Korean American women aged 40 to 77 years were recruited and randomly assigned to either the mMammogram intervention group (n=60) to receive culturally and personally tailored multilevel and multimedia messages through a mobile phone app along with health navigator services or the usual care control group (n=60) to receive a printed brochure. Outcome measures included knowledge, attitudes, and beliefs about breast cancer screening, readiness for mammography, and mammogram receipt. The feasibility and acceptability of the mMammogram intervention was also assessed.

Results

The intervention group showed significantly greater change on scores of knowledge of breast cancer and screening guidelines (P=.01). The intervention group also showed significantly greater readiness for mammography use after the intervention compared with the control group. A significantly higher proportion of women who received the mMammogram intervention (75%, 45/60) completed mammograms by the 6-month follow-up compared with the control group (30%, 18/60; P<.001). In addition, the intervention group rated satisfaction with the intervention (P=.003), effectiveness of the intervention (P<.001), and increase of knowledge on breast cancer and screenings (P=.001) significantly higher than the control group.

Conclusions

A mobile phone app–based intervention combined with health navigator service was a feasible, acceptable, and effective intervention mechanism to promote breast cancer screening in Korean American immigrant women. A flexible, easily tailored approach that relies on recent technological advancements can reach underserved and hard-to-recruit populations that bear disproportionate cancer burdens.

Breast Cancer Screening Disparity among Korean American Immigrant Women in Midwest

Purpose: Using three breast cancer screening methods such as mammogram, Clinical Breast Examination (CBE), and Breast Self-Examination (BSE), this study investigated breast cancer screening rates and its associated factors in Korean American immigrant women. Method: Cross-sectional data were obtained from 168 Korean immigrant women aged 40 and older in Midwest. The Andersen’s Behavioral Model (1995) theoretically guided this study and logistic regression was used to examine factors associated with screening receipt and performance. Results: Study participants reported low screening rates, specifically mammography and CBE uptake. About 71% of the women had a mammography at least once in their lifetime, while about 36% indicating receipt of a mammogram in the last three years. About 59% of the women received a CBE at least once in their lifetime, while about 32% had CBE in the past three years. About 74% of study participants have performed BSE at least once in their life time, while about 68% have done it in the past three years. Knowledge of screening method was consistently correlated with participant’s three breast cancer screening uptake. Additional factors that were positively associated with screening included older age, low barriers to mammograms, and lower educational attainment. Conclusions: Overall, study participants reported low rates of breast cancer screening receipt and performance. It is required to promote screening uptake among Korean immigrant women, especially women with young age, a lower level of education, and lack of health accessibility. A community-based language-appropriate health education program should be developed to increase health care access.

Effect of health-belief-model-based training on performance of women in breast self-examination

Background

Breast cancer is the most common cause of cancer death among women in the world. With prevention and examinations, including breast self-examination, the death rate will be reduced.

Objective

The purpose of this study was to determine the effect of health-belief-model-based training on the performance of women in breast self-examination in the province of Fars (Iran).

Methods

An empirical study examined the effect of an eight-week training program based on the health belief model among 144 women who visited health care centers in the city of Abadeh in Fars Province (Iran) in 2015. Data gathered through researcher-made questionnaires including awareness, components of the health belief model, performance, and demographic information. IBM-SPSS software version 20, descriptive and inferential statistical tests such as T-test, chi-square, Mann–Whitney, and repeated measurements were used for data analysis.

Results

After the intervention, a significant difference was seen in average awareness, perceived susceptibility, and performance of women (p<0.05), while it was not significant in benefits constructs, perceived barriers, and perceived severity and practice guide. After intervention, the average score of awareness was increased significantly (p<0.001). Also, the average score of performance in breast self-examination showed a significant difference (p<0.001).

Conclusion

Due to the low level of awareness of women about breast self-examination, using a health belief model with an increase of the perceived susceptibility could be effective in improving their performance in breast self-examination.

Interventions Promoting Breast Cancer Screening Among Turkish Women With Global Implications: A Systematic Review

BACKGROUND

Breast cancer is a major health concern and remains the most common malignancy in women worldwide and in Turkey. Mammography, clinical breast examination (CBE), and breast self-examination (BSE) are recommended methods to detect early breast cancer in women. Many strategies have been developed to increase the rates of mammography, CBE, and BSE among Turkish women. Despite the benefits of breast cancer screening, these modalities are still underutilized by the majority of Turkish women.

AIM

To systematically review the scientific evidence on the effectiveness of various strategies aimed at improving screening behaviors for breast cancer in Turkish women.

METHODS

A systematic review of the literature published between 2000 and 2015 was conducted, searching 10 databases of Ovid MEDLINE, PubMed, Cochrane CENTRAL Register of Controlled Trials, CINAHL, PsycINFO, Web of Knowledge, Scopus, Google Scholar, ULAKBIM Turkish Medical Database, and Council of Higher Education Thesis Center.

RESULTS

Twenty-three studies were included in the final review. The majority of the studies investigated the effects of multiple strategies to improve BSE. Group education comprised educational sessions, printed and audiovisual materials, which significantly improved BSE, CBE, and mammography screening rates at 3 months, 6 months, and 12 months after the intervention. One-to-one education demonstrated no significant difference in BSE rates at 6-month and 12-month follow-up. However, one-to-one education demonstrated significant differences in CBE and mammography rates at the 3-month follow-up.

LINKING EVIDENCE TO ACTION

The use of group education comprising a multicomponent intervention demonstrated an increase in breast-screening behaviors among Turkish women. Further research investigating the duration of educational interventions is needed in order to suggest a "dose response."

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.

Effectiveness of a multimodal standard nursing program on health-related quality of life in Chinese mainland female patients with breast cancer: protocol for a single-blind cluster randomized controlled trial

Background

Breast cancer and its treatment-related adverse effects are harmful to physical, psychological, and social functioning, leading to health-related quality of life (HRQoL) impairment in patients. Many programs have been used with this population for HRQoL improvement; however, few studies have considered the physical, psychological, and social health domains comprehensively, and few have constructed multimodal standard nursing interventions based on specific theories. The purpose of this trial is to examine the effect of a health belief model (HBM)-based multimodal standard nursing program (MSNP) on HRQoL in female patients with breast cancer.

Methods

This is a two-arm single-blind cluster randomized controlled trial (cRCT) in clinical settings. Twelve tertiary hospitals will be randomly selected from the 24 tertiary hospitals in Xi’an, China, and allocated to the intervention arm and control arm using a computer-generated random numbers table. Inpatient female patients with breast cancer from each hospital will receive either MSNP plus routine nursing care immediately after recruitment (intervention arm), or only routine nursing care (control arm). The intervention will be conducted by trained nurses for 12 months. All recruited female patients with breast cancer, participating clinical staff, and trained data collectors from the 12 hospitals will be blind with respect to group allocation. Patients of the control arm will not be offered any information about the MSNP during the study period to prevent bias. The primary outcome is HRQoL measured through the Functional Assessment of Cancer Therapy-Breast version 4.0 at 12 months. Secondary outcomes include pain, fatigue, sleep, breast cancer-related lymphedema, and upper limb function, which are evaluated by a visual analogue scale, the circumference method, and the Constant-Murley Score.

Discussion

This trial will provide important evidence on the effectiveness of multimodal nursing interventions delivered by nurses in clinical settings. Study findings will inform strategies for scaling up comprehensive standard intervention programs on health management in the population of female patients with breast cancer.
