A community-based intervention to promote breast cancer awareness and screening among Asian American women

Disparities in Cancer Mortality among Disaggregated Asian American Subpopulations, 2018-2021

Federal, state, and institutional data collection practices and analyses involving Asian Americans as a single, aggregated group obscure critical health disparities among the vast diversity of Asian American subpopulations. Using from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) Underlying Causes of Death database, we conducted a cross-sectional study using data on disaggregated Asian American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, other Asians) between 2018 and 2021. We examine deaths from 22 cancer types and in situ, benign neoplasms, identified using ICD-10 codes C00-C97 and D00-D48. Overall, our study comprised 327,311 Asian American decedents, with a mean age of death at 70.57 years (SD=2.79), wherein females accounted for approximately half of the sample (n=36,596/73,207; 49.99%). Notably, compared to the aggregated Asian American reference group, we found higher proportions of deaths from total cancers among Chinese (25.99% vs. 22.37% [ref]), Korean (25.29% vs. 22.37% [ref]), and Vietnamese (24.98% vs. 22.37% [ref]) subgroups. In contrast, total cancer deaths were less prevalent among Asian Indians (17.49% vs. 22.37% [ref]), Japanese (18.90% vs. 22.37% [ref]), and other Asians (20.37% vs. 22.37% [ref]). We identified further disparities by cancer type, sex, and age. Disaggregated data collection and analyses are imperative to understanding differences in cancer mortality among Asian American subgroups, illustrating at-risk populations with greater granularity. Future studies should aim to describe the association between these trends and social, demographic, and environmental risk factors.

Social determinants of health and US cancer screening interventions: A systematic review

There remains a need to synthesize linkages between social determinants of health (SDOH) and cancer screening to reduce persistent inequities contributing to the US cancer burden. The authors conducted a systematic review of US-based breast, cervical, colorectal, and lung cancer screening intervention studies to summarize how SDOH have been considered in interventions and relationships between SDOH and screening. Five databases were searched for peer-reviewed research articles published in English between 2010 and 2021. The Covidence software platform was used to screen articles and extract data using a standardized template. Data items included study and intervention characteristics, SDOH intervention components and measures, and screening outcomes. The findings were summarized using descriptive statistics and narratives. The review included 144 studies among diverse population groups. SDOH interventions increased screening rates overall by a median of 8.4 percentage points (interquartile interval, 1.8-18.8 percentage points). The objective of most interventions was to increase community demand (90.3%) and access (84.0%) to screening. SDOH interventions related to health care access and quality were most prevalent (227 unique intervention components). Other SDOH, including educational, social/community, environmental, and economic factors, were less common (90, 52, 21, and zero intervention components, respectively). Studies that included analyses of health policy, access to care, and lower costs yielded the largest proportions of favorable associations with screening outcomes. SDOH were predominantly measured at the individual level. This review describes how SDOH have been considered in the design and evaluation of cancer screening interventions and effect sizes for SDOH interventions. Findings may guide future intervention and implementation research aiming to reduce US screening inequities.

Persistent Disparities in Postmastectomy Breast Reconstruction and Strategies for Mitigation

For many women, breast reconstruction is an essential component of the breast cancer care continuum after mastectomy. Despite postmastectomy breast reconstruction now being a standard of care, numerous studies over the past decade have documented persistent racial disparities in breast reconstruction rates, physician referral patterns, and patient knowledge of their reconstructive options. These disparities have disproportionately impacted women of color-most specifically, African American women. Recent data have revealed racial differences in patient comorbidities, informed decision-making satisfaction, and clinical outcomes after breast reconstruction. Explicitly, African American women have significantly more risk factors for complications and less baseline knowledge regarding reconstructive options than white women. With a recent heightened attention focused on social determinants of health, studies designed to improve these racial differences have demonstrated promising results through educational outreach to underserved communities, implementation of tailored legislation promoting inclusion, diversity, and equity, and encouragement of additional recruitment of ethnically underrepresented-in-medicine surgeons. This study uses a targeted review of the literature to provide a summary of racial disparities in breast reconstruction for African American women, with our perspective on opportunities for improvement.

A cross-sectional analysis of racial disparities in US diabetes screening at the national, regional, and state level

AIMS

To determine US diabetes screening estimates in Whites, Blacks, Hispanics, Asians, Native Hawaiians/Pacific Islanders, American Indians/Alaska Natives, and Others at the national, regional, and state level.

METHODS

In this study of 2011, 2013, 2015, and 2017 Behavioral Risk Factor Surveillance System data, we used logistic regression results to generate national, regional, and state screening marginal probabilities (average adjusted predictions (AAPs)) for each race in the two American Diabetes Association recommended screening groups¹: asymptomatic overweight/obese people <45y with ≥1 diabetes risk factor and² people ≥45y.

RESULTS

Even after adjusting for sociodemographic and clinical factors, significant racial disparities in screening (p-value<.05) persist at all three geographic levels. Asians had the worst national, regional, and state level AAPs of all the races. Across all races, the Northeast had the highest regional screening levels (regional AAP: 48.4-78.58%) while the West had the lowest (regional AAP: 41.98-75.18%).

CONCLUSIONS

Study findings indicate that sociodemographic and clinical factors do not fully explain racial disparities in diabetes screening. Further research on clinician and patient attitudes towards diabetes screening are warranted in order to design and implement initiatives in US areas where certain racial groups have particularly low diabetes screening levels.

The Patient Protection and Affordable Care Act and Utilization of Preventive Health Care Services Among Asian Americans in Michigan during Pre- and Post-Affordable Care Act Implementation

Since the implementation of the Patient Protection and Affordable Care Act (ACA), significant increases in the percent of insured United States residents has steadily increased. Studies have shown that there is an increase in preventative services usage and a decrease in chronic disease burden with increased access to insurance. However, very little has been studied about how the implementation of ACA has impacted utilization of health services and health status among Asian Americans. In this study, we recruited 427 Asian Americans who attended health fairs and examined (1) changes in health care coverage and utilization of preventive health services before and after ACA, (2) health status on chronic disease risk factors, (3) comparing health services utilization by insurance status and types of insurance, and (4) identifying relationships between health care utilization and demographic factors. Study results indicate that even though the percentage of insured Asian Americans in Michigan increased significantly over study periods, health care utilization and chronic disease burden did not change significantly. The insured tended to utilize preventive health services more than the uninsured, but the types of insurance did not affect health care utilization. Gender and having a primary care physician were significant predictors in determining health care utilization. There is a need in this population for language-appropriate and culturally-sensitive education about the importance and availability of preventive services, which could improve adherence to preventive health services, thereby reducing health disparities.

Cultural Appropriateness in Health Communication: A Review and A Revised Framework

A revised framework for cultural appropriateness is offered on the basis of a systematic review of operationalizations in 44 cancer screening interventions for Asian Americans. Studies commonly conveyed the epidemiological bases of the intervention (97.7%) and used the language of the population (95.5%). Less commonly reported were strategies central to health communication: cultural features of the intervention messages (77.3%) and the cultural beliefs and values that the intervention focused on (43.2%). Few used cultural tailoring (4.5%) and none aimed to address acculturation or cultural identity. The theoretical framework most frequently used was the health belief model (27.3%) which does not explain the role of culture. More studies focused on cultural barriers (20.5%) than cultural strengths (9.1%). Our revised framework comprises six cultural appropriateness strategies of cultural identity, linguistic, perceptual features, content, constituent-involving, and socioeconomic context-adaptive. It prioritizes cultural identity to recognize the dynamics within racial ethnic groups and to inform adaptive efforts for cultural appropriateness. It emphasizes examining cultural strengths that can facilitate change, as well as reducing cultural barriers. Future research and action should address the disparities in extant health disparities research in which theory and methods are underdeveloped and underutilized for Asian Americans.

Promoting Breast Cancer Awareness and Screening Practices for Early Detection in Low-Resource Settings

Objective

Breast cancer is the most common type of cancer among women in the Philippines. Philippines has one of the highest breast cancer mortality rate and the lowest mortality-to-incidence ratio in Asia. This study has three objectives: 1) explore Filipino women's knowledge, attitudes toward, and practices of breast cancer and cancer screening, 2) examine if an educational program increases women's intention to seek future breast cancer screening, and 3) examine associations between demographic variables and breast cancer screening practices.

Materials and Methods

A total of 944 women from two urban areas (Calasciao and Tacloban City) and one rural area (Sogood) of the Philippines participated in this cross-sectional study. Study participants attended an educational program and completed study questionnaires regarding demographics, knowledge about, and practices of breast self-exams, clinical breast exams and mammography as well as reported barriers toward future screening.

Results

The results showed a disparity between knowledge of routine breast cancer screening and actuals screening behaviors. Following breast health education and screening programs, participants reported greater intention to adhere to recommended breast cancer screening guidelines. The multivariate analyses showed that education level is a significant predictor for CBE and mammography uptake in current study.

Conclusion

This study has implications for breast cancer control among women in low-resources settings. Designing and implementing effective educational programs that increase women's awareness about breast cancer and promote screening uptake are important steps to reduce the burden affected by breast cancer among women in the Philippines and other South Asian low- to middle-income countries.

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.

Interventions for raising breast cancer awareness in women

BACKGROUND

Breast cancer continues to be the most commonly diagnosed cancer in women globally. Early detection, diagnosis and treatment of breast cancer are key to better outcomes. Since many women will discover a breast cancer symptom themselves, it is important that they are breast cancer aware i.e. have the knowledge, skills and confidence to detect breast changes and present promptly to a healthcare professional.

OBJECTIVES

To assess the effectiveness of interventions for raising breast cancer awareness in women.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group's Specialised Register (searched 25 January 2016), Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12) in the Cochrane Library (searched 27 January 2016), MEDLINE OvidSP (2008 to 27 January 2016), Embase (Embase.com, 2008 to 27 January 2016), the World Health Organization's International Clinical Trials Registry Platform (ICTRP) search portal and ClinicalTrials.gov (searched 27 Feburary 2016). We also searched the reference lists of identified articles and reviews and the grey literature for conference proceedings and published abstracts. No language restriction was applied.

SELECTION CRITERIA

Randomised controlled trials (RCTs) focusing on interventions for raising women's breast cancer awareness i.e. knowledge of potential breast cancer symptoms/changes and the confidence to look at and feel their breasts, using any means of delivery, i.e. one-to-one/group/mass media campaign(s).

DATA COLLECTION AND ANALYSIS

Two authors selected studies, independently extracted data and assessed risk of bias. We reported the odds ratio (OR) and 95% confidence intervals (CIs) for dichotomous outcomes and mean difference (MD) and standard deviation (SD) for continuous outcomes. Since it was not possible to combine data from included studies due to their heterogeneity, we present a narrative synthesis. We assessed the quality of evidence using GRADE methods.

MAIN RESULTS

We included two RCTs involving 997 women: one RCT (867 women) randomised women to receive either a written booklet and usual care (intervention group 1), a written booklet and usual care plus a verbal interaction with a radiographer or research psychologist (intervention group 2) or usual care (control group); and the second RCT (130 women) randomised women to either an educational programme (three sessions of 60 to 90 minutes) or no intervention (control group). Knowledge of breast cancer symptomsIn the first study, knowledge of non-lump symptoms increased in intervention group 1 compared to the control group at two years postintervention, but not significantly (OR 1.1, 95% CI 0.7 to 1.6; P = 0.66; 449 women; moderate-quality evidence). Similarly, at two years postintervention, knowledge of symptoms increased in the intervention group 2 compared to the control group but not significantly (OR 1.4, 95% CI 0.9 to 2.1; P = 0.11; 434 women; moderate-quality evidence). In the second study, women's awareness of breast cancer symptoms had increased one month post intervention in the educational group (MD 3.45, SD 5.11; 65 women; low-quality evidence) compared to the control group (MD -0.68, SD 5.93; 65 women; P < 0.001), where there was a decrease in awareness. Knowledge of age-related riskIn the first study, women's knowledge of age-related risk of breast cancer increased, but not significantly, in intervention group 1 compared to control at two years postintervention (OR 1.8; 95% CI 0.9 to 3.5; P < 0.08; 447 women; moderate-quality evidence). Women's knowledge of risk increased significantly in intervention group 2 compared to control at two years postintervention (OR 4.8, 95% CI 2.6 to 9.0; P < 0.001; 431 women; moderate-quality evidence). In the second study, women's perceived susceptibility (how at risk they considered themselves) to breast cancer had increased significantly one month post intervention in the educational group (MD 1.31, SD 3.57; 65 women; low-quality evidence) compared to the control group (MD -0.55, SD 3.31; 65 women; P = 0.005), where a decrease in perceived susceptibility was noted. Frequency of Breast CheckingIn the first study, no significant change was noted for intervention group 1 compared to control at two years postintervention (OR 1.1, 95% CI 0.8 to 1.6; P = 0.54; 457 women; moderate-quality evidence). Monthly breast checking increased, but not significantly, in intervention group 2 compared to control at two years postintervention (OR 1.3, 95% CI 0.9 to 1.9; P = 0.14; 445 women; moderate-quality evidence). In the second study, women's breast cancer preventive behaviours increased significantly one month post intervention in the educational group (MD 1.21, SD 2.54; 65 women; low-quality evidence) compared to the control group (MD 0.15, SD 2.94; 65 women; P < 0.045). Breast Cancer AwarenessWomen's overall breast cancer awareness did not change in intervention group 1 compared to control at two years postintervention (OR 1.8, 95% CI 0.6 to 5.30; P = 0.32; 435 women; moderate-quality evidence) while overall awareness increased in the intervention group 2 compared to control at two years postintervention (OR 8.1, 95% CI 2.7 to 25.0; P < 0.001; 420 women; moderate-quality evidence). In the second study, there was a significant increase in scores on the Health Belief Model (that included the constructs of awareness and perceived susceptibility) at one month postintervention in the educational group (mean 1.21, SD 2.54; 65 women) compared to the control group (mean 0.15, SD 2.94; 65 women; P = 0.045).Neither study reported outcomes relating to motivation to check their breasts, confidence to seek help, time from breast symptom discovery to presentation to a healthcare professional, intentions to seek help, quality of life, adverse effects of the interventions, stages of breast cancer, survival estimates or breast cancer mortality rates.

AUTHORS' CONCLUSIONS

Based on the results of two RCTs, a brief intervention has the potential to increase women's breast cancer awareness. However, findings of this review should be interpreted with caution, as GRADE assessment identified moderate-quality evidence in only one of the two studies reviewed. In addition, the included trials were heterogeneous in terms of the interventions, population studied and outcomes measured. Therefore, current evidence cannot be generalised to the wider context. Further studies including larger samples, validated outcome measures and longitudinal approaches are warranted.
