“…Second, we collected detailed information on migration status: in Germany, there are few studies looking at health and healthcare differences between groups with different migration statuses since hospital data, registries or administrative data do not capture migration background. In addition, our recruitment strategy sought to include a high proportion of women with migration background, in an effort to avoid the common lack of inclusion of minority populations in cohort studies [29].…”

Background: Women with a migration background are reportedly at a higher risk of emergency caesarean section. 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. and aOR: 2.36, 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. Awareness of these findings and measures to correct these inequalities could help to improve the quality of obstetric care.

“…However, the risk of thyroid cancer among the women exposed to reproductive medication was found to be much greater in Danish women compared with US women. To our knowledge, studies concerning Western women to date have included few Asian women . It is not clear how to generalize findings in Western women to infertile Asian women.…”

“…To our knowledge, studies concerning Western women to date have included few Asian women. [4][5][6] It is not clear how to generalize findings in Western women to infertile Asian women. To our knowledge, no large study has been conducted to date among Asian women to evaluate the relationship between risk of thyroid cancer and use of reproductive medications.…”

Background The current study evaluated whether the risk of developing thyroid cancer in Asian women was associated with infertility and the use of fertility drugs. Methods The authors conducted a large, retrospective cohort study using Taiwan's National Health Insurance Research Database. From the insurance claims data, a total of 13,356 women aged 20 to 49 years who were diagnosed with infertility from 2000 through 2013 were included in the infertile group, and 53,424 women without a history of infertility were selected as fertile comparisons and were frequency matched by age and year of diagnosis. Both groups were followed up to 2013 to calculate incident thyroid cancer. Poisson regression analysis was used to estimate the incidence rate ratio (IRR). Results The incidence of thyroid cancer was 1.9‐fold greater in the infertile group compared with the comparison group (2.85 vs 1.53 per 10,000 person‐years), with an adjusted IRR of 1.80 (95% confidence interval [95% CI], 1.70‐1.92) for the infertile group. Higher cancer incidence was demonstrated for the infertile group after 7 years of follow‐up, with an adjusted IRR of 4.39 (95% CI, 4.03‐4.78) compared with the comparison group. Among infertile women, those who had taken the fertility drug clomiphene were found to have a reduced incidence of thyroid cancer compared with those who were treated without the drug (2.69 vs 3.42 per 10,000 person‐years), with an adjusted IRR of 0.86 (95% CI, 0.75‐0.99). However, the cancer incidence in infertile women being treated with clomiphene was nearly 6‐fold greater than that in fertile women taking the drug. Conclusions The results of the current study provide evidence that women with infertility are at an increased risk of developing thyroid cancer.

“…Although the USA has the highest total number of immigrants in the world, and the highest funding on medical research, this pattern is probably a consequence of research politics in the country encouraging trials to report information on the ethnicity of participants, 23 which can be used in immigration studies. However, a recent scoping review of birth cohort studies in 20 European countries reported that, although 70% of them collected information about migration history or ethnicity, only 26% used that information for data analyses or planned to do so 24 . Countries in the Middle East, with the highest levels of immigration in the world, were poorly represented in our material, as were countries with less inclusive or responsive health systems and restrictive integration policies, such as most of Central and Southeast Europe 25 …”

Background: Disparities in health between immigrants and their host populations have been described across countries and continents. Hence, interventions for improving health targeting general populations are not necessarily effective for immigrants. Aims: To conduct a systematic search of the literature evaluating health interventions for immigrants; to map the characteristics of identified studies including range of interventions, immigrant populations and their host countries, clinical areas targeted and reported evaluations, challenges and limitations of the interventions identified. Following the results, to develop recommendations for research in the field. Methods: A scoping review approach was chosen to provide an overview of the type, extent and quantity of research available. Studies were included if they empirically evaluated health interventions targeting immigrants and/or their descendants, included a control group, and were published in English (PubMed and Embase from 1990 to 2015). Results: Most of the 83 studies included were conducted in the USA, encompassed few immigrant groups and used a randomized controlled trial (RCT) or cluster RCT design. Most interventions addressed chronic and non-communicable diseases and attendance at cancer screening services, used individual targeted approaches, targeted adult women and recruited participants from health centres. Outcome measures were often subjective, with the exception of interventions for cardiovascular risk and diabetes. Generally, authors claimed that interventions were beneficial, despite a number of reported limitations. Conclusions: Recommendations for enhancing interventions to improve immigrant health are provided to help researchers, funders and health care commissioners when deciding upon the scope, nature and design of future research in this area.
