Factors that influence mammography use and breast cancer detection among Mexican-American and African-American women

Disparities in screening mammography utilization among Hispanic women in rural Texas from 2002 to 2018

PURPOSE

To examine the trends of racial/ethnic and urban-rural disparities in screening mammography use with a focus on Hispanic women in rural Texas, as well as to further investigate barriers to mammography screening practices.

METHODS

A serial cross-sectional study was conducted on screening mammography including eligible female respondents (≥ 40 years) from the Texas Behavioral Risk Factor Surveillance System survey from 2002 to 2018.

FINDINGS

Weighted descriptive analyses showed persistent racial/ethnic and urban-rural disparities in mammography screening rates among eligible women (≥ 40 years) in Texas. Overall, the mammography screening rates for women in rural areas were significantly lower than women in urban areas with a mean rate of 64.09% versus 70.89% (p < 0.001). Rural Hispanic women had the lowest mean mammography screening rate (55.98%) among all eligible women which is 16.27% below the mean mammography screening rate of non-Hispanic white women in urban areas. Weighted logistic regression model revealed that women with no health insurance or primary care providers were 52% (95% Confidence Interval [CI] 0.36-0.63, p < 0.001) or 54% (95% CI 0.35-0.6, p < 0.001) less likely having an up-to-date mammography screening compared with women with health insurance or primary care providers, respectively.

CONCLUSIONS

Our study demonstrated significant and persistent racial and urban-rural disparities in screening mammography utilization among Hispanic women compared with non-Hispanic white women from 2002 to 2018. Healthcare access is a major contributor to these disparities. It highlights the need for wide-scale interventions from public health and policymakers targeting under screened racial minorities and rural regions population to promote screening mammography services among disadvantaged population.

Determinants of Protective Healthcare Services Awareness among Female Syrian Refugees in Turkey

War-related migration may deprive people of access to a regular healthcare system and cause new diseases to be battled. Since refugee women are more vulnerable to diseases during this period, protective healthcare services awareness is critical for early disease diagnosis. Following the civil war that triggered the migration of millions of Syrians, an extensive survey was undertaken in coordination with the World Health Organization Country Office in Turkey to explore the health status of Syrian refugees in Turkey. Employing the survey data, we aimed to investigate the determinants of the awareness of protective health services (Pap smear test, mammogram, HIV test) among female Syrian refugees. Logit regression analysis was applied in order to investigate the determinants of the awareness of protective health services among the female refugee population. The results revealed a notably low rate of awareness of protective health services among female Syrian refugees. Furthermore, the association of explanatory variables, including socioeconomic factors, healthcare use, and health literacy with the protective health services awareness, was found to be significant.

Delays in Care Associated With Non-English-Speaking Patients With Breast Cancer

BACKGROUND

Breast cancer care requires coordination between multiple diagnostic and treatment modalities. Disparities such as age, race/ethnicity, and socioeconomic status are associated with delays in care. This study investigates whether primary language is associated with delays in breast cancer diagnosis and treatment before and through radiotherapy (RT).

PATIENTS AND METHODS

This study was an institutional retrospective matched-cohort analysis of women treated with breast RT over 2 years. A total of 65 non-English-speaking (NES) patients were matched with 195 English-speaking (ES) patients according to stage, age, and chemotherapy delivery. Key time intervals along the breast cancer care path from initial findings through RT were recorded. Data were analyzed in a mixed model with matching as the random effect. The impact of race and insurance status was analyzed in addition to language.

RESULTS

Significant delays were found for NES patients, which varied by race. NES Latina patients experienced the longest delay, with a mean total care-path time of 13.53 months (from initial findings to end of RT) versus 8.18 months for all ES patients (P<.0001). Specifically, their mean total care-path time was 5.97 months longer than that of ES Latina patients (P=.001) and 5.80 months longer than that of ES White patients (P<.0001). In addition, NES Latina patients had a significantly longer total care-path time than NES patients of other races/ethnicities (P=.001). Delays were specifically seen between initial clinical or radiographic findings and diagnostic mammogram (P=.001) and between biopsy and resection (P=.044). Beyond language, race/ethnicity was itself associated with delays between resection and start of RT (P=.032) and between start and end of RT (P=.022).

CONCLUSIONS

Language is associated with pre-RT delays in breast cancer care, especially for NES Latina patients. Delays are most pronounced before diagnostic mammograms, but they also exist before resection and RT. Future work should target NES patients to assist their progress along the care path.

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.

Medicaid Expansion and Breast Cancer Screening in Appalachia and Non-Appalachia, United States, BRFSS 2003 to 2015

Background:

Prior data suggests that breast cancer screening rates are lower among women in the Appalachian region of the United States. This study examined the changes in breast cancer screening before and after the implementation of the Affordable Care Act Medicaid expansion, in Appalachia and non-Appalachia states.

Methods:

Data from the Behavioral Risk Factor Surveillance System between 2003 and 2015 were analyzed to evaluate changes in breast cancer screening in the past 2 years among US women aged 50-74 years. Multivariable adjusted logistic regression and generalized estimating equation models were utilized, adjusting for sociodemographic, socioeconomic, and health-care characteristics. Data were analyzed for 2 periods: 2003 to 2009 (pre-expansion) and 2011 to 2015 (post-expansion) comparing Appalachia and non-Appalachia states.

Results:

The prevalence for of self-reported breast cancer screening in Appalachia and non-Appalachia states were 83% and 82% (P < .001), respectively. In Appalachian states, breast cancer screening was marginally higher in non-expanded versus expanded states in both the pre-expansion (relative risk [RR]: 1.002, 95% confidence interval [CI]: 1.002-1.003) and post-expansion period (RR: 1.001, 95% CI: 1.001-1.002). In non-Appalachian states, screening was lower in non-expanded states versus expanded states in both the pre-expansion (RR: 0.98, 95% CI: 0.97-0.98) and post-expansion period (RR: 0.95, 95% CI: 0.95-0.96). There were modest 3% to 4% declines in breast cancer screening rates in the pos-texpansion period regardless of expansion and Appalachia status.

Conclusions:

Breast cancer screening rates were higher in Appalachia versus non-Appalachia US states and higher in expanded versus nonexpanded non-Appalachia states. There were modest declines in breast cancer screening rates in the post-expansion period regardless of expansion and Appalachia status, suggesting that more work may be needed to reduce administrative, logistical, and structural barriers to breast cancer screening services.

Impact of acculturation on breast cancer treatment and survivorship care among Mexican American patients in Texas

PURPOSE

Given the increasing number and diversity of cancer survivors in the USA and persistent racial/ethnic disparities in breast cancer care, we sought to examine the role of acculturation in adherence to recommended surgical treatment and survivorship care recommendations.

METHODS

Study participants included 343 Mexican American women with stage I to III breast cancer who participated in the Ella Binational Breast Cancer Study and were treated at The University of Texas MD Anderson Cancer Center in Houston, Texas, between March 2007 and June 2011. Participants completed a questionnaire measuring acculturation, and clinical and demographic variables were obtained from an institutional database. Multivariable logistic regression models were constructed to examine differences in surgical procedures received and adherence to long-term survivorship care by acculturation level.

RESULTS

Bilingual (odds ratio [OR] = 1.85; 95% confidence interval [CI] = 0.85-4.02, P = .11) and English-dominant women (OR = 2.39; 95% CI = 1.02-5.61, P = .04) were more likely to receive breast-conserving surgery (versus mastectomy) than were Spanish-dominant women. Among all patients, adherence to surveillance mammography and clinic visits decreased over time; the decline in clinic visit adherence was statistically significant (P = .005). Although no statistically significant association was found between acculturation and adherence to long-term survivorship care, receipt of breast-conserving surgery (versus mastectomy) was significantly associated with higher adherence to surveillance mammograms.

CONCLUSION

Acculturation may play a role in decision-making about surgical management of breast cancer, and further studies with larger samples are needed to explore its role in adherence to survivorship care recommendations. Findings from this study may help identify patients requiring additional support while making decisions pertaining to their cancer treatment and survivorship care.

Trends in breast and colorectal cancer screening among U.S. adults by race, healthcare coverage, and SES before, during, and after the great recession

The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.

Breast cancer delay in Latinas: the role of cultural beliefs and acculturation

Cultural beliefs about breast cancer may act as a barrier to Latina women seeking preventive services or timely follow-up for breast symptoms regardless of access. This study examines the association between factors and breast cancer cultural beliefs and the extent to which cultural beliefs are associated with delays in breast cancer care. Participants who were Latina, ages 30-79, and had been diagnosed with a primary breast cancer were examined (n = 181). Interviews included a 15-item cultural beliefs scale spanning beliefs inconsistent with motivation to seek timely healthcare. Self-reported date of symptom discovery, date of first medical presentation, and date of first treatment were used to construct measures of prolonged patient, clinical, and total delay. Logistic regression with model-based standardization was used to estimate crude and confounder-adjusted prevalence differences for prolonged delay by number of cultural beliefs held. Women held a mean score of three cultural beliefs. The belief most commonly held was, "Faith in God can protect you from breast cancer" (48 %). Holding three or more cultural beliefs was associated with lower acculturation, lower socioeconomic status and less access to care (p < 0.01). After adjusting for age, education, income, acculturation, trust, and insurance, likelihood of prolonged total delay remained 21 percentage points higher in women who held a higher number cultural beliefs (p = 0.02). Cultural beliefs may predispose Latina women to prolong delays in seeking diagnosis and treatment for breast symptoms. Cultural beliefs represent a potential point of intervention to decrease delays among Latina breast cancer patients.

Latinas' Mammography Intention Following a Home-Based Promotores-Led Intervention

Despite increases in mammography rates among Latinas, screening rates remain lower than in non-Latina Whites and Latinas typically present with breast cancer at a later stage. Trained lay community workers (promotores) have been successfully used to increase screening mammography intention in Latinas. Little is known, however, about the potential mechanisms of these interventions, such as increased breast cancer knowledge (knowledge) and social interactions concerning mammography practices (social engagement). This prospective pre-post study examined this gap in the literature by (1) documenting changes in knowledge and social engagement after receipt of a promotores-based intervention; and (2) establishing if post-intervention knowledge and social engagement predicted mammography intention, after adjusting for socio-demographic and lifetime mammography history. There were significant increases in knowledge and social engagement about mammography. Finally, post-intervention social engagement was a significant predictor of mammography intention. Future promotores-based interventions should focus on enhancing social engagement to improve mammography intention and use.

Travel by public transit to mammography facilities in 6 US urban areas

We examined lack of private vehicle access and 30 minutes or longer public transportation travel time to mammography facilities for women 40 years of age or older in the urban areas of Boston, Philadelphia, San Antonio, San Diego, Denver, and Seattle to identify transit marginalized populations - women for whom these travel characteristics may jointly present a barrier to clinic access. This ecological study used sex and race/ethnicity data from the 2010 US Census and household vehicle availability data from the American Community Survey 2008-2012, all at Census tract level. Using the public transportation option on Google Trip Planner we obtained the travel time from the centroid of each census tract to all local mammography facilities to determine the nearest mammography facility in each urban area. Median travel times by public transportation to the nearest facility for women with no household access to a private vehicle were obtained by ranking travel time by population group across all U.S. census tracts in each urban area and across the entire study area. The overall median travel times for each urban area for women without household access to a private vehicle ranged from a low of 15 minutes in Boston and Philadelphia to 27 minutes in San Diego. The numbers and percentages of transit marginalized women were then calculated for all urban areas by population group. While black women were less likely to have private vehicle access, and both Hispanic and black women were more likely to be transit marginalized, this outcome varied by urban area. White women constituted the largest number of transit marginalized. Our results indicate that mammography facilities are favorably located for the large majority of women, although there are still substantial numbers for whom travel may likely present a barrier to mammography facility access.

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

BACKGROUND

Incidence rates for breast cancer are higher among Mexican-American (MA) women in the United States than women living in Mexico. Studies have shown higher prevalence of breast cancer risk factors in more acculturated than less acculturated Hispanic/Latinas in the United States. We compared the prevalence of behavioral risk factors and family history of breast cancer by level of acculturation and country of residence in women of Mexican descent.

METHODS

Data were collected from 1,201 newly diagnosed breast cancer patients living in Mexico (n = 581) and MAs in the United States (n = 620). MA participants were categorized into three acculturation groups (Spanish dominant, bilingual, and English dominant); women living in Mexico were used as the referent group. The prevalence of behavioral risk factors and family history of breast cancer were assessed according to acculturation level, adjusting for age at diagnosis and education.

RESULTS

In the adjusted models, bilingual and English-dominant MAs were significantly more likely to have a body mass index of 30 kg/m(2) or greater, consume more than one alcoholic beverage a week, and report having a family history of breast cancer than women living in Mexico. All three U.S. acculturation groups were significantly more likely to have lower total energy expenditure (≤533 kcal/d) than women in Mexico. English-dominant women were significantly less likely to ever smoke cigarettes than the Mexican group.

CONCLUSIONS

Our findings add to the limited scientific literature on the relationships among acculturation, health behavior, and family history of breast cancer in Mexican and MA women.

Mammography use and mode of detection among breast cancer patients in Estonia

The aim of this study was to examine past mammography use and mode of detection among breast cancer (BC) patients in Estonia, a country that has low screening coverage and high BC mortality. Women newly diagnosed with primary BC in Estonia in 2008-2010 were interviewed. Determinants of past mammography use and the detection of BC by mammography were studied using multivariate logistic regression. Among 977 participants, almost half reported no mammograms prior to the detection of BC. Overall, 22% of the cases were detected by mammography (16% by screening mammography). Detection by mammography was strongly related to age, past mammography use, and obesity. Among cases detected by mammography, 10% were stage III/IV at diagnosis (32% among cases detected by other modes). This study showed low mammography utilization and high rate of self-detection of BC in Estonia. Increased detection by mammography would help diagnose the disease at an earlier stage and consequently avoid premature BC deaths. Efforts should be undertaken to increase participation in screening and improve the availability of mammography among older and high-risk women. The results are likely to be relevant for other countries and population groups with low screening coverage.

Care and survival of Mexican American women with node negative breast cancer: historical cohort evidence of health insurance and barrio advantages

We hypothesized 3-way ethnicity by barrio by health insurance interactions such that the advantages of having adequate health insurance were greatest among Mexican American (MA) women who lived in barrios. Barrios were neighborhoods with relatively high concentrations of MAs (60% or more). Data were analyzed for 194 MA and 2,846 non-Hispanic white women diagnosed with, very treatable, node negative breast cancer in California between 1996 and 2000 and followed until 2011. Significant interactions were observed such that the protective effects of Medicare or private health insurance on radiation therapy access and long term survival were largest for MA women who resided in MA barrios, neighborhoods that also tended to be extremely poor. These paradoxical findings are consistent with the theory that more facilitative social and economic capital available to MA women in barrios enables them to better absorb the indirect and direct, but uncovered, costs of breast cancer care.

Race/ethnicity and the socioeconomic status gradient in women's cancer screening utilization: a case of diminishing returns?

Using three years (2006, 2008, 2010) of nationally representative data from the Behavioral Risk Factor Surveillance System, I assessed the socioeconomic status (SES) gradient for odds of receiving a mammogram in the past two years and a Pap test in the past three years among White, Black, Hispanic, and Asian women living in the U.S. Mammogram and Pap test utilization were less likely among low-SES women. However, women of color experience less benefit than Whites from increasing SES for both screenings; as income and education increased, White women experienced more pronounced increases in the likelihood of being screened than did women of color. In what might be referred to as paradoxical returns, Asian women actually experienced a decline in the likelihood of obtaining a recent Pap test at higher levels of education. My findings suggest that women of color differ from Whites in the extent to which increasing socioeconomic resources is associated with increasing cancer screening utilization.

Reproductive and hormonal risk profile according to language acculturation and country of residence in the Ella Binational Breast Cancer Study

BACKGROUND

We compared the distribution of breast cancer reproductive and hormonal risk factors by level of acculturation and country of residence in women of Mexican descent.

METHODS

To compare the distribution of breast cancer reproductive and hormonal risk factors by level of acculturation and country of residence in women of Mexican descent, taking into account level of education, we analyzed data on 581 Mexican and 620 Mexican American (MA) women with a history of invasive breast cancer from the Ella Binational Breast Cancer Study. An eight-item language-based acculturation measure was used to classify MA women. Multivariate logistic regression was used to test associations between language acculturation, country of residence, and reproductive and hormonal risk factors.

RESULTS

After adjustment for age and education, compared to women residing in Mexico, English-dominant MAs were significantly more likely to have an earlier age at menarche (<12 years; odds ratio [OR]=2.08; 95% confidence interval [CI], 1.30-3.34), less likely to have a late age at first birth (≥30 years; OR=0.49; 95% CI, 0.25-0.97), and less likely to ever breastfeed (OR=0.13; 95% CI, 0.08-0.21).

CONCLUSIONS

Differences in reproductive and hormonal risk profile according to language acculturation and country of residence are evident; some of these were explained by education. Results support continued efforts to educate Mexican and MA women on screening and early detection of breast cancer along with promotion of modifiable factors, such as breastfeeding.

Association between parity and obesity in Mexican and Mexican-American women: findings from the Ella binational breast cancer study

Obesity at diagnosis of breast cancer is associated with higher all-cause mortality and treatment-associated toxicities. We evaluated the association between parity and obesity in the Ella study, a population of Mexican and Mexican-American breast cancer patients with high parity. Obesity outcomes included body mass index (BMI) ≥30 kg/m(2), waist circumference (WC) ≥35 in (88 cm), and waist-to-hip-ratio (WHR) ≥0.85. Prevalence of obesity ([BMI] ≥ 30 kg/m(2)) was 38.9 %. For WC, the multivariate odds ratio (OR) (95 % confidence interval [CI]) for having WC ≥ 35 inches in women with ≥4 pregnancies relative to those with 1-2 pregnancies was 1.59 (1.01-2.47). Higher parity (≥4 pregnancies) was non-significantly associated with high BMI (OR = 1.10; 95 % CI 0.73-1.67). No positive association was observed for WHR. Our results suggest WC is independently associated with high parity in Hispanic women and may be an optimal target for post-partum weight loss interventions.

Health insurance mediation of the Mexican American non-Hispanic white disparity on early breast cancer diagnosis

We examined health insurance mediation of the Mexican American (MA) non-Hispanic white (NHW) disparity on early breast cancer diagnosis. Based on social capital and barrio advantage theories, we hypothesized a 3-way ethnicity by poverty by health insurance interaction, that is, that 2-way poverty by health insurance interaction effects would differ between ethnic groups. We secondarily analyzed registry data for 303 MA and 3,611 NHW women diagnosed with breast cancer between 1996 and 2000 who were originally followed until 2011. Predictors of early, node negative (NN) disease at diagnosis were analyzed. Socioeconomic data were obtained from the 2000 census to categorize neighborhood poverty: high (30% or more of the census tract households were poor), middle (5% to 29% poor) and low (less than 5% poor). Barrios were neighborhoods where 50% or more of the residents were MA. Primary health insurers were Medicaid, Medicare, private or none. MA women were 13% less likely to be diagnosed early with NN disease (RR = 0.87), but this MA-NHW disparity was completely mediated by the main and interacting effects of health insurance. Advantages of health insurance were largest in low poverty neighborhoods among NHW women (RR = 1.20) while among MA women they were, paradoxically, largest in high poverty, MA barrios (RR = 1.45). Advantages of being privately insured were observed for all. Medicare seemed additionally instrumental for NHW women and Medicaid for MA women. These findings are consistent with the theory that more facilitative social and economic capital is available to MA women in barrios and to NHW women in more affluent neighborhoods. It is there that each respective group of women is probably best able to absorb the indirect and direct, but uncovered, costs of breast cancer screening and diagnosis.

Prevalence and correlates of breast and cervical cancer screening among a Midwest community sample of low-acculturated Latinas

BACKGROUND

Low adherence to cervical and breast cancer (CBC) screening recommendations contributes to high CBC mortality among Latinas.

PURPOSE

To estimate the prevalence of, and factors associated with, last 12-month Pap smear and mammogram receipt among a Midwest community sample of low-acculturated Latinas.

METHODS

We conducted a cross-sectional study with 278 Latina immigrants in Dane County, Wisconsin. Participants completed a self-administered questionnaire. We estimated multivariate logistic regression models to identify factors associated with CBC screening receipt.

RESULTS

Rates of last 12-month Pap smear and mammogram receipt were 56.8% and 39.4%, respectively. Age, knowledge of screening recommendations, and having a regular health care provider were independently associated with both Pap smear and mammogram receipt. Having ever used Planned Parenthood and fear of cancer were uniquely correlated with Pap smear and mammogram receipt, respectively.

CONCLUSIONS

Modifiable individual, structural, and cultural factors contribute to suboptimal rates of CBC screening among low-acculturated Latino immigrants.
