Predictors Of Mammography Screening Research Articles

Predictive factors of breast cancer mammography screening among Iranian women.

Understanding the factors that influence women's cancer screening behavior is crucial in reducing cancer mortality through early detection. Therefore, the objective of this study was to examine the status of mammography and related factors among women who presented to the health centers of Khorasan Razavi province, Iran. For this study, a sample of 251,011 women who visited healthcare centers affiliated with Mashhad University of Medical Sciences was selected. The study examined several variables, including sociodemographic information, current smoking, nutrition status, and physical exercise. All analyses were performed using Python programming language and SPSS software. Furthermore, to handle imbalanced data, we used SMOTE balancing method that is an oversampling method and produce synthetic samples from the minority class. The factors of age, education, being employed, having children, family history of cancer, physical activity, smoking status, and diet were all predictors of mammography screening. Moreover, findings showed that age and family history of breast cancer were most important variables to predict mammography status, respectively. By examining various variables such as dietary habits, exercise, smoking, and demographic properties, it sheds light on the relationships between these factors and mammography screening. This provides valuable insights into the associations between breast cancer screening behavior and preventive lifestyle behaviors. By targeting both preventive lifestyle choices and breast cancer screening behaviors, interventions can effectively promote positive changes in behavior and ultimately reduce the incidence and impact of breast cancer.

Abstract B111: Previous mammography experience as a predictor of mammography adherence among Hispanic/Latinas living in the Northeast United States

Abstract Background: Similar to non-Hispanic Black women, Hispanic/Latino women are more likely to be diagnosed with later-stage breast cancer than White women, and their mammography screening rates are lower than those of both groups. Although the literature generally focuses on women's behavior to identify predictors of mammography screening, we hypothesized that selected factors associated with prior mammography experience would impact future screening. From a large prospective study of cancer screening in Hispanic/Latinas living in the Northeast US, the purpose of this investigation was to determine how previous mammography experiences influenced adherence to mammography screening guidelines over 2.5-4 years of follow-up. Methods: Among 1,456 community-living Hispanic/Latinas ages 40 to 75 who had received at least one screening mammogram at the time of their baseline interview and consented to medical record review, we considered “mammography experience” in predicting annual screening mammography (documented screening mammogram within 12 months + 1-month lag time), in accordance with recommendations promulgated by the American Cancer Society (and widely followed) during the study period. Using multivariate logistic regression, we identified independent predictors of adherence to recommended guidelines after adjusting for core sociodemographic, access to care, and medical factors. Key predictors included characteristics of provider (gender, race/ethnicity), ease of communication and use of interpreters, being treated with respect, believing that mammography-related pain was minimized as much as possible, communication of results, and general satisfaction. Odds Ratios (ORs) and 95% Confidence Intervals (CI) are reported. Results: 54% of Hispanic/Latino women were adherent to recommended mammography screening guidelines over the follow up period. Although needing help with communicating with medical staff and not speaking the same language as the radiologic technologist were significant in bivariate analyses, only 2 “experience” variables were significant predictors after multivariate adjustment: 1) Women who were told the results of their earlier mammogram at the time of the test were less likely (OR= 0.80; 95% CI 0.63, 0.97) to adhere to annual screening guidelines compared to patients who were not told their results; and 2) compared to women who did not have a usual care provider, having a female doctor increased a woman's odds of being compliant with recommended guidelines (OR = 1.40, 95% CI 1.05, 1.77), whereas having a male usual care provider did not (OR = 0.86, 95% CI 1.05, 1.77). Conclusion: In a prospective look at adherence to mammography screening guidelines in Hispanic/Latino women living in the Northeast US, having a female usual care provider was associated with adherence to mammography screening guidelines. This finding requires further study, particularly in this subpopulation. Citation Format: Beth A.

Breast cancer screening in transgender patients: findings from the 2014 BRFSS survey

Transgender patients undergoing transitions often receive cross-sex hormonal therapies, placing them at uncertain risk for developing breast cancer. There is limited population-based information about the extent to which transgender patients undergo mammography screening. Our purpose was to determine the extent to which transgender patients undergo mammography screening using nationally representative survey data. Transgender participants between ages 40-74 in the 2014 Behavioral Risk Factor Surveillance System survey were included. Proportions undergoing mammography screening in the last year or two years were calculated stratified by age category and transition status [male to female(MtF), female to male(FtM), non-conforming]. For each transition status, predictors of mammography screening were calculated using logistic regression. 220 transgender patients were within 40-74years old(35% were MtF, 51% were FtM, 14% were non-conforming). 60.0% underwent mammography screening within the last year (MtF-54.5%, FtM-64.3%, non-conforming-58.1%). 74.1% underwent screening within the last two years(MtF-70.1%, FtM-75.9%, non-conforming-77.4%). For all transgender patients, income category (OR 1.16, 0.82-1.64), higher education category (OR 1.09, 0.31-3.86) and health insurance (OR 0.38, 0.10-1.41) were not associated with increased adherence to mammography screening. Transgender patients were comparably likely to undergo mammography screening compared with non-transgender patients (Adjusted OR 0.97, 0.58-1.62). High proportions of transgender survey respondents undergo mammography screening (57.9-66.1% within the last year, 71.9-74.4% within the last two years) in our sample, proportions comparable to non-transgender survey respondents.

Breast cancer screening in transgender patients: Findings from the 2014 BRFSS survey.

1564 Background: Transgender patients undergoing transitions often receive cross sex hormonal therapies, placing them at uncertain risk for developing breast cancer. There is limited population-based information about the extent to which transgender patients undergo mammography screening. Our purpose was to determine the extent to which transgender patients undergo mammography screening using nationally representative survey data. Methods: Transgender participants in the 2014 Behavioral Risk Factor Surveillance System survey were included. Proportions undergoing mammography screening in the last year or two years were calculated stratified by age category and transition status (male to female(MtF), female to male(FtM), non-conforming(people who do not follow societal notions how they should look or act based on the sex they were assigned at birth)). For each transition status, predictors of mammography screening (demographics, indices of access to health care) were calculated using logistic regression. Results: 656 transgender patients were included (343 were MtF, 203 were FtM and 110 classified themselves as gender non-conforming). For MtF respondents, 61.5% of women underwent mammography screening within the last year (71.9% within last two years). For FtM respondents, 66.1% underwent mammography screening within the last year (74.2% within the last two years). For gender non-confirming transgender patients, 57.9% underwent mammography screening within the last year (74.4% within the last two years). For all transgender patients, income category (OR 1.16, 0.82 - 1.64), higher education category (OR 1.09, 0.31 - 3.86) and health insurance (OR 0.38, 0.10 - 1.41) were not associated with increased adherence to mammography screening. Adjusted for age, education, race and income, transgender patients were comparably likely to undergo mammography screening compared with non-transgender patients (OR 0.97, 0.58 – 1.62). Conclusions: High proportions of transgender survey respondents undergo mammography screening (57.9 – 66.1% within the last year, 71.9 – 74.4% within the last two years), proportions comparable to non-transgender survey respondents.

Abstract C70: Selected Prospective Predictors of Mammography Screening in Hispanic/Latinas Living in the Northeast, US

Abstract Background & Objectives: Hispanic/Latinas (H/Las) are more likely to be diagnosed with later staged breast cancer when compared with White women. Mammography screening, an important early detection tool, is effective when received at regular intervals. National data suggest that mammography screening rates in H/Las are lower than reported for Whites and African Americans. However, little is known about the predictors of screening adherence in the largely immigrant population of Hispanic/Latinas living in the Northeast, US. This is the first report of prospectively measured predictors of non-adherence to mammography screening guidelines in a largely unstudied population, Hispanic/Latinas living in the Northeast, US. As a starting point, we report here on selected core socio-demographic, acculturation, access to care, and medical variables as predictors of mammography screening over 2 to 4 years of follow-up. Methods: We conducted hour long telephone interviews with 1600 community-living Hispanic/Latino women, ages 40-75, seeking care at primary care clinics in the 4 cities with the largest Hispanic populations in Connecticut, US. Women with no prior history of breast cancer or biopsy were eligible for inclusion in our study. We collected detailed information on socio-demographic, access to care, medical, health knowledge and belief variables. Screening mammography that occurred during 2-4 years of follow-up was derived from radiology records (n=1570; 98% consented to record review). Bivariate and multivariate predictors (core socio-demographic, access to care, acculturation, and medical variables) of adherence to annual screening guidelines in place at the time of study are reported. Results: Of the 1570 women included in the final cohort, 870 (55.4%) were non-adherent to guidelines calling for annual mammography screening and 610 (38.9%) were non-adherent to guidelines calling for biennial mammography screening. In multivariate analyses that controlled for marital status, education, income, insurance status, continuity of care, selected health factors and acculturation variables, younger (age less than 50), OR = 1.52 (95% CI, 1.22, 1.89) and women who reported fair or poor compared with good or very good self-rated health (OR = 1.30, 95% CI 1.0, 1.62) were non-adherent to guidelines calling for annual screening. In contrast, women with relatively poor English language skills were 30% less likely to be non-adherent (OR 0.70, 95% CI 0.56, 0.96). Conclusions: In a study of a large cohort of mostly immigrant Hispanic/Latino women living in the Northeast, US, preliminary results suggest that younger women and those women who report that they are not in good health are at risk for non-adherence to mammography screening guidelines. There is a suggestion that despite a language barrier, some immigrant women may screen more than women who were born in the US. A better understanding of how acculturation factors interact with other patient characteristics is needed. Citation Format: Beth A.

Predictors of Mammography Screening among Iranian Women Attending Outpatient Clinics in Tehran, Iran

Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.

Predictors of Mammography Screening Among Ethnically Diverse Low-Income Women

Breast cancer is the second leading cause of cancer deaths among women in the United States. Minority women are less likely to be screened and more likely to die from breast cancer than are Caucasian women. Although some studies have examined ethnic disparities in mammography screening, no study has examined whether there are ethnic disparities among low-income, ethnically diverse women. The present study was designed to determine whether there are ethnic disparities in mammography screening and predictors of screening among low-income African American, Mexican American, and Caucasian women, and to determine whether the disparities and predictors vary across ethnic groups. The participants were 146 low-income women who were Mexican American (32%), African American (31%), or Caucasian (37%). Statistical analyses were performed to assess the relationships between mammography screening during the past 2 years and potential predictors of screening, both within ethnic groups and for the combined sample. The results varied depending on whether analyses combined ethnic groups or were performed within each of the three ethnic groups. It is, therefore, important to examine within-group differences when examining ethnic disparities in predictors of mammography.

Mammography screening after breast cancer diagnosis in a first degree female relative: age group differences (United States)

To examine age group differences in predictors of mammography screening in women with a first-degree female relative (FDFR) with recent diagnosis of breast cancer. A cohort study of 577 women ages 18 and over with a FDFR diagnosed with incident stage 0-III breast cancer was conducted. Telephone interviews were conducted at baseline, 6 months and 12 months. Logistic regression was used to model factors associated with mammography screening since diagnosis. Mammography rates were 32%, 71% and 75% for women aged 18-39, 40-49 and 50 and above, respectively. Among the youngest group, belief in cancer screening effectiveness, mammography history and MD recommendation predicted mammography. For those 40-49, excellent self-rated health, perceived similarity of personality to the patient and higher intrusive thoughts predicted mammography. Perceived similarity of health care utilization to the patient and higher risk perceptions were associated with mammography among women aged 50 and above. Mammography rates were high among women aged 40-49 and 50 and above, and considerable among women aged 18-30, even in view of the lack of evidence-based guidelines. Continued attention should be paid to the 25-30% of older women who do not report screening.

Knowledge About Breast Cancer and Participation in a Faith-Based Breast Cancer Program and Other Predictors of Mammography Screening Among African American Women and Latinas

This article assessed the impact of knowledge of breast cancer and type and intensity of participation in a church-based breast cancer education program and other factors on mammography screening among African Americans and Latinas. Logistic regression was used to assess the impact of these factors on self-reported mammography utilization. Passive participation in church-sponsored activities, measured by breast cancer information that was heard, seen, or read, was found to be significantly associated with the likelihood of mammography use among African Americans. Moreover, African Americans who reported hearing, seeing, or reading about mammograms at their churches four or more times were 15 times more likely to report mammography use within the past year than were those who encountered information only once. Messages from pastors and church bulletin announcements were the most significant predictors. An increase in knowledge was not associated with higher mammography use. For Latinas, none of the hypothesized knowledge or participation variables was found to be significant. The results suggest that faith-based breast cancer programs can be effective by adopting tailored strategies to raise awareness about the importance of early detection.

Predicting mammography utilization through model generation

Abstract Currently, breast cancer screening with periodic mammography offers our best hope of reducing breast cancer mortality. The purpose of this report is to determine the best predictors of mammography screening using structural equation modelling with LISREL analysis. Using the Health Belief Model as a theoretical framework, the variables of perceived susceptibility, seriousness, benefits, barriers, health motivation, control, and suggestion by a health care provider, were hypothesized to directly impact mammography compliance with demographic/experiential variables indirectly influencing compliance. A total of 581 women selected through random digit dialling were interviewed in their homes by a graduate research assistant. A total of 51% of the compliance was predicted by direct and indirect paths. Variables that significantly predicted compliance with a direct path included health motivation, age, suggestion by a health care provider, knowledge and symptoms.
