However, it also has some potential harms, such as overdiagnosis and overtreatment. Therefore, it is necessary that women receive sufficient and balanced information to enable informed decision-making. We examined knowledge about benefits and harms of the MSP in Germany among first-time invitees of different socio-demographic backgrounds. Methods: This observational study assessed knowledge about benefits and harms of the MSP among women who were invited to the MSP for the first time by six multiple choice items, using a postal survey. We investigated (i) single items of knowledge, (ii) the distribution of sufficient knowledge stratified by education, migration status and invitation, and (iii) possible determinants of sufficient knowledge by analyzing Odds Ratios (ORs) using bivariate and multivariate logistic regression. Results: In total, 5397 women included in the analyses. 46.1\% of the study population had sufficient knowledge about benefits and harms of the MSP. However, women with low educational level and migration background had higher proportions of insufficient knowledge and used most frequently the option "don't know". Women had the most difficulties answering the numeric question and the question about the target group correctly. Results from the logistic regression showed that the odds of having sufficient knowledge were higher among well-educated women (OR 3.84, 95\%CI 3.24-4.55), among women who already received the MSP invitation (OR 1.38, 95\%CI 1.20-1.59) and lowest among Turkish women (OR 0.14, 95\%CI 0.07-0.25). Conclusions: Women with low education and migration background need adapted information regarding benefits and harms of the MSP and are important target groups for further developing the information material about mammography screening to reduce disparities in knowledge and enable informed decision-making.}, language = {en} } @misc{KaucherKhilKajueteretal., author = {Kaucher, Simone and Khil, Laura and Kaj{\"u}ter, Hiltraud and Becher, Heiko and Reder, Maren and Kolip, Petra and Spallek, Jacob and Winkler, Volker and Berens, Eva-Maria}, title = {Breast cancer incidence and mammography screening among resettlers in Germany}, series = {BMC public health}, volume = {20}, journal = {BMC public health}, number = {1}, doi = {10.1186/s12889-020-08534-7}, pages = {10}, abstract = {Background - European studies showed that women with a migration background are less likely to participate in mammography screenings than autochthonous women. However, the participation in the German mammography screening programme (MSP) among ethnic German migrants from countries of the former Soviet Union (called resettlers) is unclear so far. The aim of this study was to identify possible differences regarding MSP participation between resettlers from the FSU and the general German population. Methods - Data from two independent, complementary studies from North Rhine-Westphalia, Germany (a retrospective cohort study 1994-2013; a cross-sectional study 2013/14) were used for comparisons between resettlers and the general population: Odds Ratios (ORs) for MSP participation utilizing the cross-sectional data and time trends of breast cancer incidence rates as well as Chi-Square tests for breast cancer stages utilizing the cohort data. Results - Resettlers showed higher Odds to participate in the MSP than the general population (OR 2.42, 95\% CI 1.08-5.42). Among resettlers, a large increase in incidence rates was observed during the MSP implementation (2005-2009), resulting in stable and comparable incidence rates after the implementation. Furthermore, pre-MSP implementation, the proportion of advanced breast cancer stages was higher among resettlers than in the German population, post-MSP implementation the proportion was comparable. Conclusions - MSP participating seems surprisingly high among resettlers. An explanation for the increased willingness to participate might be the structured invitation procedure of the MSP. However, the exact reasons remain unclear and future research is needed to confirm this hypothesis and rule out the possibility of selection bias in the cross-sectional study.}, language = {en} }
