“…Since we excluded people older than 64 years in the study we reduced this negative health selection, as the occurrence of health problems is more likely in old age. In this regard, in a recent study of migrants' mortality in Sweden, Wallace and Wilson (2021) find that the data artefact could explain some, but not all, of the mortality advantage detected, thus demonstrating that such a pattern is real.…”

BACKGROUNDGender and migrant status are important factors for health. A common finding is that women report poorer health than men and that migrants' health converges with nonmigrants' health as the duration of stay in the host country increases. However, little is known about whether gender differences in health persist within migrant groups and whether the migrant-native health convergence differs by gender, especially in the Italian context. OBJECTIVEThis study aims to include the gender dimension in the analysis of the health differences between Italians and migrants by duration of stay, focusing on how gender interacts with duration of stay in determining migrants' health. METHODSWe performed multivariate logistic regression on a sample of 70,154 residents in Italy aged 20-64, using the 2013 Italian Health Survey. We modelled the association between duration of stay and three health dimensions by gender and computed predicted probabilities to show the interaction effect of gender and duration of stay. RESULTSWe found evidence of a migrant health advantage among recent migrant men and women that becomes weaker among long-term migrants. After a long duration of stay, differences in health between migrants and nonmigrants are slightly more pronounced among women than among men. CONTRIBUTIONThis is the first study in Italy that contributes to a more comprehensive understanding of the role played by gender in determining the health differences observed. The study

“…In a period of economic crisis, the increased mobility of migrants who may leave the host country to look for job opportunities in other countries or remigrate to their origin country will perhaps affect the data artefact more strongly [63]. Nevertheless, Wallace and Wilson (2021) [64], studying the Swedish context, found that the data artefact could explain some, but not all, of the mortality advantage detected. This result demonstrates that such a pattern is real.…”

Background In Europe, one of the most consistent findings is that of migrant mortality advantage in high-income countries. Furthermore, the literature shows that economic shocks, which bring worse health outcomes, can severely affect the most disadvantaged individuals. We analyse differences and changes in all-cause mortality between Italians and migrants residing in Rome before, during, and in the aftermath of the Great Recession (2001–2015) by birth-cohort. Methods The analysis is a longitudinal open cohort study. Mortality data come from the Register of the Causes of Death (58,637 deaths) and the population denominator (n = 2,454,410) comes from the Municipal Register of Rome. By comparing three time-periods (2001–2005, 2006–2010, and 2011–2015), we analyse all-cause mortality of Rome residents born, respectively, in the intervals 1937–1976, 1942–1981, 1947–1986 (aged 25–64 years at entry into observation). Computing birth-cohort-specific death rates and applying parametric survival models with age as the time-scale, we compare mortality differences between migrants and Italians by gender, area of origin, and time-period. Results Overall, we find a lower risk of dying for migrants than Italians regardless of gender (Women: HR = 0.61, 95% CI 0.56–0.66; Men: HR = 0.49, 95% CI 0.45–0.53), and a lower death risk over time for the total population. Nevertheless, such a pattern changes according to gender and migrants’ area of origin. Conclusion Given the relevance of international migrations in Europe, studying migrants’ health has proved increasingly important. The deterioration in migrant health and the gradual weakening of migrants’ mortality advantage is likely to become a public health issue with important consequences for the healthcare system of all European countries.

“…For this research, the subgroups under investigation were Polish migrants and native Irish. There is a noted lack of reliable data on migrant health in the literature [42][43][44]. Collecting migrant health data can pose significant challenges to researchers and healthcare systems for various reasons.…”

Introduction Migrants have different utilisation of healthcare services and health-related behaviours than host populations. A potential factor that may contribute to the notable differences in healthcare use and health-related behaviours between migrants and host populations is how these groups value health. Those who place a high value on health have greater healthcare-seeking practices than those who do not. Objective The aim of this study was to examine how Polish migrants and native Irish differ in health state utility valuations using a novel application of a smaller design EQ-5D-5L valuation study. Methods This study uses health preferences as a predictor of how one values health. We examined the EQ-5D-5L health preferences of 119 Polish migrants and 123 native Irish, both residing full-time in Ireland. To do so, we used a novel application of a smaller design EQ-5D-5L valuation study that consisted of 30 health states and a targeted sampling strategy coupled with a Bayesian statistical nonparametric model. We collected data from June 2018 to September 2019. Results Our results highlight that Polish migrants and native Irish differ in their health preferences for and valuation of severe health states. Polish migrants place meaningfully higher utility valuations of 0.1 or more on the three most severe health states compared with the native Irish. Conclusion This study can provide an understanding of a potential new factor underpinning some of the disparities in healthcare utilisation and health-related behaviours among migrants and host populations in Europe. This study also provides proof of principle for using a smaller design EQ-5D-5L valuation study to explore differences in health preferences among other minority subgroups, which can otherwise be hard to uncover when using the secondary analysis of national EQ-5D-5L valuation studies.
