The health of migrants in the UK and their access to healthcare is of considerable policy interest. There is evidence of ethnic inequalities in health and access to and use of healthcare but insufficient consideration of the importance of birth abroad and length of residence in the UK. This study examines indicators of health status, behaviour and healthcare use among mothers of infants in the Millennium Cohort Study, according to whether born in the UK or abroad, individual ethnic grouping, and length of residence. Our findings show there are both positive and negative health indicators associated with ethnicity, birth abroad, and length of residence and presenting results on a single factor in isolation could lead to a misinterpretation of associations. For mothers ethnicity has an important relationship with most health indicators independent of country of birth, length of residence and socio-demographic circumstances. Once adjusted for ethnicity and socio-demographic variables, association with birth abroad disappears for most health outcomes suggesting that there may not be an independent migrant penalty in health. There is a linear trend in decreasing health status with increasing length of residence but no independent association between length of residence and healthcare use. This suggests that while there are continuing barriers to good health for migrants in the receiving society as shown in other studies, factors important for one health outcome may not apply to another. Our findings challenge linear acculturation models for migrants' health in showing that a linear trend in improving socio-economic circumstances for mothers in some ethnic groups is not always associated with better health outcomes or changes in health behaviour. Our results point to a need for a comprehensive collection of information and analysis for all categories of migrants for understanding patterns of and factors underlying health and use of healthcare.

ObjectivesWe aimed to describe ethnic variations in infant mortality and explore the contribution of area deprivation, mother’s country of birth, and prematurity to these variations.MethodsWe analyzed routine birth and death data on singleton live births (gestational age≥22 weeks) in England and Wales, 2006–2012. Infant mortality by ethnic group was analyzed using logistic regression with adjustment for sociodemographic characteristics and gestational age.ResultsIn the 4,634,932 births analyzed, crude infant mortality rates were higher in Pakistani, Black Caribbean, Black African, and Bangladeshi infants (6.92, 6.00, 5.17 and 4.40 per 1,000 live births, respectively vs. 2.87 in White British infants). Adjustment for maternal sociodemographic characteristics changed the results little. Further adjustment for gestational age strongly attenuated the risk in Black Caribbean (OR 1.02, 95% CI 0.89–1.17) and Black African infants (1.17, 1.06–1.29) but not in Pakistani (2.32, 2.15–2.50), Bangladeshi (1.47, 1.28–1.69), and Indian infants (1.24, 1.11–1.38). Ethnic variations in infant mortality differed significantly between term and preterm infants. At term, South Asian groups had higher risks which cannot be explained by sociodemographic characteristics. In preterm infants, adjustment for degree of prematurity (<28, 28–31, 32–33, 34–36 weeks) fully explained increased risks in Black but not Pakistani and Bangladeshi infants. Sensitivity analyses with further adjustment for small for gestational age, or excluding deaths due to congenital anomalies did not fully explain the excess risk in South Asian groups.ConclusionsHigher infant mortality in South Asian and Black infants does not appear to be explained by sociodemographic characteristics. Higher proportions of very premature infants appear to explain increased risks in Black infants but not in South Asian groups. Strategies targeting the prevention and management of preterm birth in Black groups and suboptimal birthweight and modifiable risk factors for congenital anomalies in South Asian groups might help reduce ethnic inequalities in infant mortality.

BackgroundIn the UK, changes to legislation in 2003 regarding the free movement of people in the European Union resulted in an increase in immigration from countries that joined the EU since 2004, the Accession countries.ObjectiveTo describe and compare the maternity experiences of recent migrant mothers to those who had been resident in the UK for longer, and to UK-born women, while taking into account their region of origin.DesignCross-sectional national survey.SettingEngland, 2009.ParticipantsRandom sample of postpartum women.MeasurementsQuestionnaires asked about demographic characteristics, care during pregnancy, labour, birth and postnatally, about country of origin and, if not born in the UK, when they came to the UK. Country of origin was grouped into UK, Accession countries, and rest of the world. Recency of migration was grouped into recent arrivals (0–3 years), and earlier arrivals (4 or more years since arrival). Descriptive statistics and binary logistic regression were used to explore women's experiences of care. Stratified analyses were used to account for the strong correlation between recency of migration and region of origin.FindingsOverall, 5332 women responded to the survey (a usable response rate of 54%). Seventy-nine percent of women were UK-born. Of the 21% born outside the UK, a third were born in Accession countries. All migrants reported a poorer experience of care than UK-born women. In particular, recent migrants from the Accession countries were significantly less likely to feel that they were spoken to so they could understand and treated with kindness and respect.ConclusionsGiven the rising population of non-UK-born women of childbearing age resident in the UK and the relatively high proportion from Accession countries, it is important that staff are able to communicate effectively, through interpreters if necessary.Implications for practiceThe differences in clinical practice between women's home countries and the UK should be discussed so that women's expectations of care are informed about the options available to them.

BackgroundData recorded at birth and death registration in England and Wales have been routinely linked with data recorded at birth notification since 2006. These provide scope for detailed analyses on ethnic differences in preterm birth (PTB).ObjectivesWe aimed to investigate ethnic differences in PTB and degree of prematurity in England and Wales, taking into account maternal sociodemographic characteristics and to further explore the contribution of mother's country of birth to these ethnic differences in PTB.MethodsWe analysed PTB and degree of prematurity by ethnic group, using routinely collected and linked data for all singleton live births in England and Wales, 2006‐2012. Logistic regression was used to adjust for mother's age, marital status/registration type, area deprivation and mother's country of birth.ResultsIn the 4 634 932 births analysed, all minority ethnic groups except ‘Other White’ had significantly higher odds of PTB compared with White British babies (ORs between 1.04‐1.25); highest odds were in Black Caribbean, Indian, Bangladeshi and Pakistani groups. Ethnic differences in PTB tended to be greater at earlier gestational ages. In all ethnic groups, odds of PTB were lower for babies whose mothers were born outside the UK.ConclusionsIn England and Wales, Black Caribbean, Indian, Bangladeshi, Pakistani and Black African babies all have significantly increased odds of being born preterm compared with White British babies. Bangladeshis apart, these groups are particularly at risk of extremely PTB. In all ethnic groups, the odds of PTB are lower for babies whose mothers were born outside the UK. These ethnic differences do not appear to be wholly explained by area deprivation or other sociodemographic characteristics.
