Acculturation, Behavioral Factors, and Family History of Breast Cancer among Mexican and Mexican-American Women

Traditional Mexican dietary pattern and cancer risk among women of Mexican descent

PURPOSE

To examine the association of a traditional Mexican diet score with risk of total, breast, and colorectal cancer among women of Mexican ethnic descent in the Women's Health Initiative (WHI).

METHODS

Participants were WHI enrollees who self-identified as being of Mexican descent. Data from food frequency questionnaires self-administered at study baseline were used to calculate the MexD score, with higher scores indicating greater adherence to an a priori-defined traditional Mexican diet (high in dietary fiber, vegetables, and legumes). Incident cancers were self-reported by participants from 1993 to 2020 and adjudicated by trained physicians. We used multivariable-adjusted Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Among 2,343 Mexican descent women (median baseline age: 59 years), a total of 270 cancers (88 breast, 37 colorectal) occurred during a mean follow-up of 14.4 years. The highest tertile of MexD score was associated with a lower risk of all-cancer incidence (HR: 0.67; 95% CI 0.49-0.91; p-trend: 0.01) and colorectal cancer (HR: 0.38; 95% CI 0.14-0.998; p-trend < 0.05), with each unit increase in the MexD score associated with a 6% lower risk of all-cancer incidence (HR: 0.94; 95% CI 0.88-0.99). There was no statistically significant association with risk of breast cancer.

CONCLUSION

Consumption of a traditional Mexican diet was associated with a significantly lower risk of all-cancer incidence and colorectal cancer. Confirmation of these findings in future studies is important, given the prevalence of colorectal cancer and a growing U.S. population of women of Mexican descent.

Qualitative study of the perceived experiences and needs coping of primary caregivers of patients with breast cancer during operation in central China

PURPOSE

The purpose of this study is to gain an in-depth understanding of the intraoperative waiting period experience and needs response of primary caregivers of patients with breast cancer.

METHOD

Using a purposive sampling method, 16 primary caregivers of patients with breast cancer admitted to the Department of Breast Surgery of Shanxi Bethune Hospital from January to May 2022 were selected as study subjects. Semistructured in-depth interviews were conducted using a qualitative research method.

RESULTS

Five themes were extracted from the levels of safety and security, information transfer, emotion management, psychological adjustment and role adaptation: safety first and intraoperative care, lack of information and misdirection, negative emotions and tired of coping, ineffective worry and overthinking, and role multiplicity and bearing alone, respectively.

CONCLUSION

The intraoperative waiting period for primary caregivers of patients with breast cancer felt multidimensional and had less than optimal needs satisfaction. Healthcare professionals should use the existing needs as an entry point to give appropriate interventions to enhance the coping ability of caregivers of patients with breast cancer.

Development and Modification of a Culturally Tailored Education Program to Prevent Breast Cancer in Korean Immigrant Women in New York City

Breast cancer (BC) is the most common cancer in Korean American (KA) women. In view of its high prevalence in these women, their low screening rates, and the cultural influence of BC risk factors in their lifestyles, we developed a community-based culturally tailored BC prevention program, the Korean Breast Cancer Risk Reduction Program (KBCRRP). Guided by the PRECEDE-PROCEDE and health belief models, the KBCRRP was developed to achieve four goals: (1) healthy weight, (2) physically active lifestyle, (3) healthy diet, and (4) BC screening and adherence. KBCRRP combines effective multicomponent strategies for BC screening and a group-based lifestyle intervention incorporating traditional Korean health beliefs and is tailored for BC risk reduction. In this paper, we provide an overview of the program, the process of program development, implementation, and evaluation, and modification during the COVID-19 pandemic. The initial program involved 8 weeks of in-person group education sessions led by interdisciplinary healthcare professionals and 16 weeks of follow-up involving smartphone applications, phone calls, and text messaging from trained lifestyle coaches. Participants received opportunities to obtain free mammography during the program. After feasibility testing, the program was modified by incorporating participants' feedback. During the COVID-19 pandemic, we provided the program using the Zoom video platform. Participants' recruitment and retention during the pandemic was successful, reflecting the fact that virtual delivery of group-based education was a feasible and acceptable alternative to in-person sessions. Collaboration with community organizations serving the target population is the key to developing and sustaining a successful community-based educational program.

Evaluation of disparities in maintaining healthy lifestyle behaviors among female cancer survivors by race/ethnicity and US nativity

BACKGROUND

There are well-known racial/ethnic disparities in maintaining healthy lifestyle behaviors throughout cancer survivorship among US-born women. Less is known about these associations among women born outside the US, as these women may experience disparities in survivorship care due to the lack of access to culturally appropriate health services. We evaluated disparities in the associations between race/ethnicity and US nativity and the likelihood of meeting recommendations for maintaining a healthy lifestyle during cancer survivorship.

METHODS

2044 female cancer survivors contributed data from the National Health and Nutrition Examination Survey (NHANES) (1999-2018). Adjusted odds ratios (aORs) and 95 % confidence intervals (CIs) were calculated with multivariable logistic regression models to measure the association between independent variables (race/ethnicity, US nativity, length of time in the US) and outcomes (obesity, meeting weekly physical activity (PA) recommendations, smoking history, alcoholic drinks/day) overall and by comorbidity.

RESULTS

Most survivors were breast cancer survivors (27.6 %), non-Hispanic white (64.2 %), and US native (84.5 %). Compared to US native survivors, foreign-born survivors were less likely (aOR, 0.30, 95 % CI, 0.10-0.87) to not meet PA recommendations, while foreign-born survivors living in the US ≥ 15 years were 2.30 times more likely (95 % CI, 1.12-4.73) to not meet PA recommendations. Having at least one comorbidity modified (p-interaction< 0.05) the relationships between US nativity and length of time in the US.

CONCLUSION

Our findings provide new evidence for disparities in maintaining healthy lifestyle behaviors among female cancer survivors and can help inform lifestyle interventions for female cancer survivors from different racial/ethnic backgrounds.

Dónde Están? Latinx/Hispanic Representation in the Oncology Workforce: Present and Future

This manuscript reviews the status of Hispanic/Latinx physicians in oncology, the benefits and challenges to achieving equitable representation, and potential solutions and actions to increase diversity in the oncology workforce. Persons of Hispanic/Latinx origin comprise 18.7% of the population and 16.8% of the adult population in the United States but are only 4.7% of practicing oncologists. The reasons for the lack of representation of Hispanic/Latinx individuals in medicine are multifaceted and include discrimination and biases, exclusionary practices, financial barriers, and lack of role modeling. As a result, patients are deprived the benefits of a representative workforce, such as improved access, enhanced culturally and linguistically competent care, and minimization of health disparities. Solutions included in the manuscript include a description of efforts by ASCO to improve the representativeness of the oncology workforce through its awards programs and educational efforts, especially for Hispanic/Latinx clinicians. The manuscript also outlines individual actions that attending physicians, senior oncologists, oncology leaders, and hospital/cancer center leadership can take to improve the diversity of the oncology workforce and support our Latinx/Hispanic trainees and colleagues. Improving the representativeness of the oncology workforce will require collective action by institutions, medical societies, and individuals. Nevertheless, widespread commitment to creating an inclusive and supported workforce is necessary to ensure the quality of care for minority patients, reduce existing cancer care disparities, and advance innovation in oncology.

Systematic review of neighborhood socioeconomic indices studied across the cancer control continuum

BACKGROUND

There is extensive interest in understanding how neighborhood socioeconomic status (nSES) may affect cancer incidence or survival. However, variability regarding items included and approaches used to form a composite nSES index presents challenges in summarizing overall associations with cancer. Given recent calls for standardized measures of neighborhood sociodemographic effects in cancer disparity research, the objective of this systematic review was to identify and compare existing nSES indices studied across the cancer continuum (incidence, screening, diagnosis, treatment, survival/mortality) and summarize associations by race/ethnicity and cancer site to inform future cancer disparity studies.

METHODS

Using PRISMA guidelines, peer-reviewed articles published between 2010 and 2019 containing keywords related to nSES and cancer were identified in PubMed.

RESULTS

Twenty-four nSES indices were identified from 75 studies. In general, findings indicated a significant association between nSES and cancer outcomes (n = 64/75 studies; 85.33%), with 42/64 (65.63%) adjusting for highly-correlated individual SES factors (e.g., education). However, the direction of association differed by cancer site, race/ethnicity, and nSES index.

CONCLUSIONS

This review highlights several methodologic and conceptual issues surrounding nSES measurement and potential associations with cancer disparities. Recommendations pertaining to the selection of nSES measures are provided, which may help inform disparity-related disease processes and improve the identification of vulnerable populations in need of intervention.

Mammography Screening Among Latinas: Does Gender and Ethnic Patient-Physician Concordance Matter?

Breast cancer is the most commonly diagnosed cancer among Latinas. Dominican women in particular have a higher lifetime risk of breast cancer than do other Latinas in the U.S. This study examines how gender, ethnic, and language concordance between providers and patients are associated with recent mammography screening for Latina immigrant women from the Dominican Republic. We conducted structured interviews, in Spanish, with 419 Dominican women aged 40 years or older living in New York City. Using bivariate analysis and logistic regressions, we tested whether patient-provider gender, ethnic, and language concordance was associated with recent mammography when controlling for demographic covariates, breast cancer screening knowledge, and self-rated health. Gender concordance predicted recent mammography after controlling for covariates (β = 0.13). Neither ethnic nor language concordance significantly predicted recent mammography. Our findings suggest that promotion of patient-provider gender concordance may help reduce health disparities among Latinos/as and other minority groups across the United States.

Breast Cancer Survivorship Experiences of Urban Hispanic Women

The purpose of this study was to explore determinates of health that impact survivorship of urban Hispanic breast cancer survivors who are at risk for experiencing poorer outcomes than others. Some challenges have been characterized, but gaps in our knowledge of the impact of some of the social determinates of health remain. Challenges likely exist prior to a diagnosis of cancer and may amplify in intensity during survivorship, potentially shortening survival and quality of life of these women. A narrative, focus group was conducted with a group of urban Hispanic breast cancer survivors. A series of linked vignettes describing survivorship challenges and late effects of breast cancer pathology and treatment were used to stimulate discussion. Three themes impacting survivorship were identified. The themes included communication (health literacy), isolation, and social support and financial cost. Communication issues resulted in delays in treatment denial of services. While these themes in cancer survivors are independent of residence (rural, suburban, or urban) and across ethnic groups, some unique issues were identified in urban Hispanic breast cancer survivors. Members of the healthcare team are in a unique position to enhance survivor's health literacy, advocate for programmatic efforts to enhance navigation roles in the hospital and communities, decrease delays in initiating care, and decrease the rate of patients lost.

Patterns of Alcohol Abstinence in Mexican Women Residing in the United States: Effects of Nativity and Duration in the United States

OBJECTIVES

Explore changes in abstinence rates in Mexican women (MW) residing in the United States based on nativity and time in the United States as an indicator risks for future alcohol-related disorders.

DESIGN

A secondary analysis of data from the National Health Interview Survey evaluated rates of abstinence between 2000 and 2017. A logistic regression was completed to address the impact of age, years in the United States, sample years.

SAMPLE

A total of 29,860 MW surveyed over an 18-year period that included those born in and outside the United States.

PRIMARY RESEARCH VARIABLES

Dependent variable was abstinence status; independent variables included nativity, year of survey, age, years in the United States (if immigrant).

RESULTS

Immigrant MW showed higher rates of alcohol abstinence than U.S.-born MW across all years, but regardless of place of birth, fewer MW are abstaining over time. Among immigrant MW, those only in the United States greater than 15 years had a greater risk of becoming a drinker than those in the United States less than 5 years.

CONCLUSION

There are declining rates of alcohol abstinence among MW regardless of immigration status. The lower rate of abstinent MW increases their risk for alcohol-related disorders. Assessing MW's use of alcohol and providing targeted education is essential.

Latina young adults' use of health care during initial months in the United States

We examined social ecological predictors of health care utilization among Latina young adults during their initial year after immigration to the United States. Participants were 530 Latinas (ages 18-23) who immigrated to Miami-Dade County, Florida, 11.5 months before assessment. We used multiple logistic regression to test predictors of health care usage. Approximately 36% utilized care. Dimensions of marianismo differentially associated with usage. Usage also was more likely for participants who reported more social network attachment, better health, greater neighborhood cohesion, and possessed a job and health insurance. Findings inform interventions to increase health care usage globally among women after immigration.

Risk factors for breast cancer in the breast cancer risk model study of Guam and Saipan

BACKGROUND

Chamorro Pacific Islanders in the Mariana Islands have breast cancer incidence rates similar to, but mortality rates higher than, those of U.S. women. As breast cancer risk factors of women of the Mariana Islands may be unique because of ethnic and cultural differences, we studied established and suspected risk factors for breast cancer in this unstudied population.

METHODS

From 2010-2013, we conducted retrospective case-control study of female breast cancer (104 cases and 185 controls) among women in the Mariana Islands. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for each of various lifestyle-related factors from logistic regression of breast cancer, in all women and in pre- and postmenopausal women separately. Tests for interaction of risk factors with ethnicity were based on the Wald statistics for cross-product terms.

RESULTS

Of the medical and reproductive factors considered - age at menarche, breastfeeding, number of live births, age at first live birth, hormone use, and menopause - only age at first live birth was confirmed. Age at first live birth, among parous women, was higher among cases (mean 24.9 years) than controls (mean 23.2 years); with increased breast cancer risk (OR=2.53; 95% CI, 1.04-6.19 for age≥30y compared to <20y, P for trend=0.01). Of the lifestyle factors -body mass index, waist circumference, physical activity, alcohol and betel-nut intake, and education - only waist circumference (OR=1.65; 95% CI 0.87-3.14 for the highest tertile group compared to the lowest, P for trend=0.04) was significantly associated with breast cancer risk and only in Filipino women. The association with many other established risk factors, such as BMI, hormone use and physical activity, were in the expected direction but were not significant. Associations for family history of breast cancer and alcohol intake were not evident CONCLUSIONS: The results provide a basis for cancer prevention guidance for women in the Mariana Islands.

Representation of Minorities and Women in Oncology Clinical Trials: Review of the Past 14 Years

Purpose:

Many cancer clinical trials lack appropriate representation of specific patient populations, limiting their generalizability. Therefore, we determined the representation of ethnic minorities and women in cancer clinical trials.

Methods:

Enrollment data from all therapeutic trials reported as completed in ClinicalTrials.gov from 2003 to 2016 were analyzed. We calculated enrollment fractions (EFs) for each group, defined as the number of enrollees divided by the 2013 Surveillance, Epidemiology, and End Results (SEER) database cancer prevalence.

Results:

Of 1,012 clinical trials, 310 (31%) reported ethnicity with a total of 55,689 enrollees. Participation varied significantly across ethnic groups. Non-Hispanic whites were more likely to be enrolled in clinical trials (EF, 1.2%) than African Americans (EF, 0.7%; P < .001) and Hispanics (EF, 0.4%; P < .001). A decrease in African American (6% v 9.2%) and Hispanic (2.6% v 3.1%) enrollment was observed when compared with historical data from 1996 to 2002. Younger patients (age younger than 65 years) were more likely to be enrolled in clinical trials than the elderly (64% v 36%; P < .001). Low recruitment of female patients was observed in clinical trials for melanoma (35%), lung cancer (39%), and pancreatic cancer (40%).

Conclusion:

We observed a decrease in recruitment of minorities over the past 14 years compared with historical data. African Americans, Hispanics, and women were less likely to be enrolled in cancer clinical trials. Future trials should take extra measures to recruit participants that adequately represent the US cancer population.
