We compared breastfeeding practices among women with and without a migration background in Bielefeld, Germany, using data from a birth cohort. Methods: In 2013-16, we conducted 967 standardised interviews with women aged over 18 during pregnancy or shortly after birth, collecting data on breastfeeding uptake and duration intention, as well as on socio-economic and migration background. Bivariate and multivariate analyses were performed, adjusting for clinical factors (e.g. age, parity, birthweight). Results: Breastfeeding uptake was more common among women with a migration background than among non-immigrants (88.9\% vs. 83\%, p < 0.05). It was particularly high among 2nd and 3rd generation women (92\%). Women with a migration background tended to intend to breastfeed longer than non-immigrants (6.2\% vs 7.6\% between 6 months and one year and 0.67\% vs. 2.53\% beyond one year). When controlling for clinical and socio-economic characteristics, only a statistically significant correlation between breastfeeding uptake and the opinion of the mother and of the partner with regard to breastfeeding remained, with a negative opinion decreasing the chances of uptake (OR 0.5; CI 0.25-0.79 and OR 0.2; CI 0.12-0.36, respectively). Mothers and partners of women with migration background were more likely to strongly support breastfeeding than those of non-immigrants. Duration intention was positively associated with having a migration background (1.98; CI 1.10-3.55) and negatively associated with income, with higher income decreasing likelihood of breastfeeding beyond 6 months (OR 0.6; CI 0.44-0.94). Conclusions: This study found differences in breastfeeding uptake and duration intention among women with and without a migration background. This calls for public health actions targeting different socio-economic groups if one wants to come closer to the WHO recommended breastfeeding rates.

The aim of this study was to describe nursing care support for cancer patients and to analyse whether these patients need more care assistance than other persons in need for care. Methods: This was a registry linkage study conducted in 2011. Cases were identified from the population-based cancer registry for the Muenster District in north-western Germany and in factually anonymised form linked by a semi-automatic probabilistic procedure (the standard procedure of the cancer registry) with medical examination records of patients applying for assistance and nursing care support from the regional statutory health insurance. The application records of 4,029 patients with colon, breast and prostate cancer were compared to a reference group of 13,104 non-cancer patients. Results: In only 41.7\% of colon, 45.8\% of breast and 37.4\% of prostate cancer patients was the malignancy the main underlying diagnostic cause for the application of assistance and nursing care. These patients were on average younger (mean age 71.1 vs. 76.8 years) than the non-cancer reference group, required higher levels of support (79.5 vs. 58.1\% "considerable" or higher level care need) and their applications were less likely to be rejected (odds ratios [ORs] 0.26, 0.28, and 0.31, respectively). By contrast, the proportion of successful applications and the level of support granted did not differ between multimorbid cancer patients with other main diagnoses as compared to non-cancer applicants. Conclusion: Patients with colon, breast or prostate cancer do not need per se more nursing care than non-cancer patients. Only if cancer is the main underlying diagnosis for nursing care support, higher levels of support are needed.}, language = {en} } @misc{WandschneiderSauzetBreckenkampetal., author = {Wandschneider, Lisa and Sauzet, Odile and Breckenkamp, J{\"u}rgen and Spallek, Jacob and Razum, Oliver}, title = {Kleinr{\"a}umige Merkmale und ihr Einfluss auf ein niedriges Geburtsgewicht - eine theoriegeleitete Analyse}, series = {14.

There is evidence that this is due in part to suboptimal antenatal care use and quality of care. Despite the fact that migrant women and descendants of migrants are often at risk of socioeconomic disadvantage, there is, in comparison, scarce and incomplete evidence on the role of socioeconomic position as an independent risk factor for emergency caesarean delivery. We therefore investigate whether and how migration background and two markers of socioeconomic position affect the risk of an emergency caesarean section and whether they interact with each other. METHODS: In 2013-2016, we recruited women during the perinatal period in Bielefeld, Germany, collecting data on health and socioeconomic and migration background, as well as routine perinatal data. We studied associations between migration background (1st generation migrant, 2nd/3rd generation woman, no migration background), socioeconomic status (educational attainment and net monthly household income), and the outcome emergency caesarean section. RESULTS: Of the 881 participants, 21\% (n = 185) had an emergency caesarean section. Analyses showed no association between having an emergency caesarean section and migration status or education. Women in the lowest (< 800€/month) and second lowest (between 800 and 1750€/month) income categories were more likely (aOR: 1.96, CI: 1.01-3.81; and aOR: 2.36, CI: 1.27-4.40, respectively) to undergo an emergency caesarean section than women in the higher income groups. CONCLUSIONS: Migration status and education did not explain heterogeneity in mode of birth. Having a low household income, however, increased the chances of emergency caesarean section and thereby contributed towards producing health disadvantages.

Hence, neighbourhood is a complex mixture of factors which cannot be simply defined by a delineation on a map, making common definitions of neighbourhood (e.g. administrative borders) problematic. We present a new concept for the evaluation of contextual health inequalities in an urban setting. Methods: An ego-centred approach to neighbourhood effects on health allows to establish to what degree the health outcomes of a person are on average correlated to the health outcomes of his/her neighbours. This approach does not necessitate the definition of what a neighbourhood is, or of its boundaries. Using data from the BaBi birth cohort following up 958 mother-child pairs in Bielefeld/Germany we illustrate how the method provides information about the spatial structure of a possible association between unmeasured neighbourhood factors and birthweight. Spatially correlated birthweight indicates a neighbourhood effect on maternal health. Results: A parametric model of the correlation structure gives two indicators: a distance after which health outcomes are no longer correlated (practical range), and the strength of correlation (RSV). We modelled birthweight directly and residuals after controlling for (spatially correlated) covariates. After adjusting for the mother's demographics and neighbourhood characteristics, birthweights remained spatially correlated with RSV of 11\% and a practical range of 128 m. Conclusions: Modelling the spatial correlation of a health outcome provides a measure of the degree of health correlation, thus offering new evidence on the production of health inequalities while incorporating current modelling approaches. Moreover, it measures heterogeneity in a city. This could be used as an indicator for policy makers or town planners to identify areas in need of socioeconomic investment.}, language = {en} } @misc{LudwigDoyleLoeffleretal., author = {Ludwig, Angelique and Doyle, Ina-Merle and L{\"o}ffler, Antje and Breckenkamp, J{\"u}rgen and Spallek, Jacob and Razum, Oliver and Miani, Celine}, title = {The impact of psychosocial factors on breastfeeding duration in the BaBi-Study.

First, we select small-area characteristics based on a conceptual model and measure them. Then, we empirically analyse the impact of these characteristics on LBW. Material and methods: Individual data were provided by the birth cohort study "Health of infants and children in Bielefeld/Germany." The sample consists of 892 eligible women and their infants distributed over 80 statistical districts in Bielefeld. Small-area data were obtained from local noise maps, emission inventory, Google Street View and civil registries. A linear multilevel analysis with a two-level structure (individuals nested within statistical districts) was conducted. Results: The effects of the selected small-area characteristics on LBW are small to non-existent, no significant effects are detected. The differences in proportion of LBW based on marginal effects are small, ranging from zero to 1.1\%. Newborns from less aesthetic and subjectively perceived unsafe neighbourhoods tend to have higher proportions of LBW.

In Germany, they include antenatal classes, breastfeeding classes and pregnancy-specific yoga or gymnastics courses. Studies suggest that various types of non-medical ANC carry benefits for both the women and their babies. Little is known about the uptake of non-medical ANC among different socioeconomic population subgroups, but one may expect lower utilization among socio-economically disadvantaged women. We analyzed factors contributing to the utilization of non-medical ANC in general and antenatal classes in particular. Methods: Baseline data of the Bielefeld BaBi birth cohort (2013-2016) and the Berlin perinatal study (2011-2012) were analyzed. Comparing the two cohorts allowed to increase the socio-economic and migration background variance of the study population and to capture the effect of the local context on uptake of services. Multivariate logistic regression analyses were performed to study associations between the uptake of non-medical ANC and socio-economic and migration status.ResultsIn Berlin and Bielefeld, being a first generation migrant and having lower levels of education were associated with lower non-medical ANC uptake. In Berlin, being a 2nd generation woman or having a low income was also associated with lower uptake. Conclusions for Practice: Our study suggests that non-medical ANC remains in some part the prerogative of non-migrant, well-educated and economically privileged women.

A way to move forward in assessing these pathways direction is to explore the spatial structure of health phenomena to generate hypotheses and examine whether the neighbourhood characteristics are able to explain this spatial structure. We compare the spatial structure of two cardiovascular disease risk factors in three European urban areas, thus assessing if a non-measured neighbourhood effect or spatial processes is present by either modelling the correlation structure at individual level or by estimating the intra-class correlation within administrative units. Methods: Data from three independent studies (RECORD, DHS and BaBi), covering each a European urban area, are used. The characteristics of the spatial correlation structure of cardiovascular risk factors (BMI and systolic blood pressure) adjusted for age, sex, educational attainment and income are estimated by fitting an exponential model to the semi-variogram based on the geo-coordinates of places of residence. For comparison purposes, a random effect model is also fitted to estimate the intra-class correlation within administrative units. We then discuss the benefits of modelling the correlation structure to evaluate the presence of unmeasured spatial effects on health. Results: BMI and blood pressure are consistently found to be spatially structured across the studies, the spatial correlation structures being stronger for BMI. Eight to 22\% of the variability in BMI were spatially structured with radii ranging from 100 to 240 m (range). Only a small part of the correlation of residuals was explained by adjusting for the correlation within administrative units (from 0 to 4 percentage points). Discussion: The individual spatial correlation approach provides much stronger evidence of spatial effects than the multilevel approach even for small administrative units. Spatial correlation structure offers new possibilities to assess the relevant spatial scale for health. Stronger correlation structure seen for BMI may be due to neighbourhood socioeconomic conditions and processes like social norms at work in the immediate neighbourhood.}, language = {en} } @misc{MianiLudwigDoyleetal., author = {Miani, C{\´e}line and Ludwig, Angelique and Doyle, Ina-Merle and Breckenkamp, J{\"u}rgen and H{\"o}ller-Holtrichter, Chantal and Spallek, Jacob and Razum, Oliver}, title = {The role of education and migration background in explaining differences in folic acid supplementation intake in pregnancy: Results from a German birth cohort study}, series = {Public Health Nutrition}, journal = {Public Health Nutrition}, issn = {1475-2727}, doi = {10.1017/S1368980021003621}, pages = {1 -- 24}, abstract = {Objective: Official German recommendations advise women to start taking folic acid supplementation (FAS) before conception and continue during the first pregnancy trimester to lower the risk of birth defects. Women from lower socioeconomic background and ethnic minorities tend to be less likely to take FAS in other European countries. As little is known about the determinants of FAS in Germany, we aimed to investigate the association between FAS and formal education and migration background, adjusting for demographic factors. Design: We used data (2013-2016) on nutrition and socioeconomic and migration background from the baseline questionnaire of the BaBi cohort study. We performed multivariate regressions and mediation analyses. Setting: Bielefeld, Germany. Participants: 947 women (pregnant or who had given birth in the past two months). Results: 16.7\% of the participants (158/947) didn't use FAS. Migration-related variables (e.g. language, length of stay) were not associated with FAS in the adjusted models. FAS was lower in women with lower level of formal education and in unplanned pregnancies. Reasons given by women for not taking FAS were unplanned pregnancy and lack of knowledge of FAS. Conclusions: Health practitioners may be inclined to see migrant women as an inherently at-risk group for failed intake of FAS. However, it is primarily women who did not plan their pregnancy, and women of lower formal education level, who are at risk. Different public health strategies to counter low supplementation rates should be supported, those addressing the social determinants of health (i.e. education) and those more focussed on family planning.}, language = {en} }
