HIV testing and counselling for migrant populations living in high-income countries: a systematic review.

Background: The barriers to HIV testing and counselling that migrants encounter can jeopardize proactive HIV testing that relies on the fact that HIV testing must be linked to care. We analyse available evidence on HIV testing and counselling strategies targeting migrants and ethnic minorities in high-income countries. Methods: Systematic literature review of the five main databases of articles in English from Europe, North America and Australia between 2005 and 2009. Results: Of 1034 abstracts, 37 articles were selected. Migrants, mainly from HIV-endemic countries, are at risk of HIV infection and its consequences. The HIV prevalence among migrants is higher than the general population’s, and migrants have higher frequency of delayed HIV diagnosis. For migrants from countries with low HIV prevalence and for ethnic minorities, socio-economic vulnerability puts them at risk of acquiring HIV. Migrants have specific legal and administrative impediments to accessing HIV testing—in some countries, undocumented migrants are not entitled to health care—as well as cultural and linguistic barriers, racism and xenophobia. Migrants and ethnic minorities fear stigma from their communities, yet community acceptance is key for well-being. Conclusions: Migrants and ethnic minorities should be offered HIV testing, but the barriers highlighted in this review may deter programs from achieving the final goal, which is linking migrants and ethnic minorities to HIV clinical care under the public health perspective.

Indicadores de salud reproductiva y perinatal en mujeres inmigrantes y autóctonas residentes en Cataluña y en la Comunitat Valenciana (2005-2006)

OBJECTIVESnTo determine the prevalence of teenage maternity, preterm birth and low birth weight in Spanish and immigrant mothers from Latin America, eastern Europe, Maghreb and sub-Saharan Africa resident in Catalonia and Valencia from 2005 and 2006.nnnMETHODSnUsing data from congenital metabolic disorders registers in both regions, proportions and 95% confidence intervals were obtained for the following: 1) mothers aged less than 20 years; 2) preterm (<37 weeks) and very preterm (<32 weeks) births; and 3) low birth weight (<2500g) and very low birth weight (<1500g) neonates. The calculations were performed for mothers from each of the geographical areas of origin (Spain, Latin America, Eastern Europe, Maghreb and Sub-Sahara). These proportions were compared in Spanish-born and immigrant women and the significance of differences was assessed using chi-squared tests.nnnRESULTSnThe prevalence of teenage mothers was between three and five times higher in immigrants than in Spanish women, the highest rate being found in women from eastern Europe. Preterm births, very preterm births and very low birth weight were more frequent in eastern European women than in Spanish women. The prevalence of prematurity and very low birth weight was higher in sub-Saharan mothers than in Spanish women.nnnCONCLUSIONSnThe number of births in teenage mothers was higher in immigrant mothers from all origins than in Spanish women. The highest rates of low birth weight and preterm births were found in women from eastern Europe and sub-Saharan Africa.

Caesarean section rates in immigrant and native women in Spain: the importance of geographical origin and type of hospital for delivery.

BACKGROUNDnSpain has become a principal destination for immigrants and delivery is the major reason for hospitalization in this population. However, research about inequities between native and immigrant women regarding the quality of the care received during pregnancy and delivery is still scarce. One of the indicators used to evaluate the quality of the obstetric care is the rate of caesarean sections (CSs).nnnMETHODSnA cross-sectional study of 215 379 single deliveries from Spanish and immigrant women from Latin America, East Europe and Maghreb was carried out in Spain in 2005-06. Prevalence of CS according to maternal and neonatal characteristics was calculated by geographical origin. Two associations were explored by means of multiple logistic regression analysis. First, the association between geographical origin and the risk of CS in public or private hospitals separately, and, second, the risk of CS for women from the same geographical origin depending on whether they delivered at public or private hospitals.nnnRESULTSnOverall, the risk of CS was lower for immigrants as a whole than for native women (odds ratio (OR) = 0.83 95% confidence interval (CI) = 0.80-0.85), but the risk varied markedly by area of origin, being higher for Latin Americans (OR = 1.09 95% CI = 1.05-1.13) and lower for East Europeans (OR = 0.61 95% CI = 0.57-0.66) and Maghrebians (OR = 0.60 95% CI =0.57-0.63). Public hospitals followed the overall pattern of risk. CS risk was higher in private than in public hospitals for all groups. However, the increase in risk was higher for immigrant than for natives.nnnCONCLUSIONnImmigrants in Spain are a heterogeneous population regarding the risk of CS. Geographical origin and type of hospital are key aspects underlying such a risk.

Differences in Preterm and Low Birth Weight Deliveries Between Spanish and Immigrant Women: Influence of the Prenatal Care Received

OBJECTIVESnTo compare the risk of preterm and low birth weight among newborns from native and immigrant women and to assess the role of prenatal care in the association between the ethnic origin of the women and their reproductive outcomes.nnnMETHODSnCross-sectional study of 21,708 women giving birth between 1997 and 2008 in a region of Spain. Multinomial logistic regression models were adjusted to evaluate associations between mothers area of origin and adverse reproductive outcomes and to assess the role of prenatal care in the occurrence of adverse reproductive results.nnnRESULTSnOur results indicate a worse prenatal control in immigrants than in natives. Very preterm birth (VPTB) and very low birth weight (VLBW) were greater among immigrants (odds ratio [OR], 1.78; 95% confidence interval [95% CI], 1.14-2.79 for VPTB and OR, 1.73; 95% CI, 0.89-3.33 for VLBW) but after adjustment for prenatal care the differences were substantially reduced (OR, 1.43; 95% CI 0.85-2.42 for VPTB and OR 1.15; 95% CI 0.53-2.52 for VLBW).nnnCONCLUSIONSnGiven the positive impact of prenatal care on reproductive results, strategies to improve it among immigrant women should be implemented. The difference found in the direction of the association between area of origin and different categories of low birth weight and preterm suggest that very and moderate categories should be analyzed separately in immigrant studies.

Breastfeeding initiation in immigrant and non-immigrant women in Spain

Research about inequities between native and immigrant women regarding the quality of health care is still scarce. Initiation of breastfeeding in hospital is considered a quality care indicator. In this study, we explore the association between the geographical origin of the women and the establishment of breastfeeding in Spanish hospitals. Prevalence of breastfeeding initiation is higher for women from Latin America, Eastern Europe, Maghreb or sub-Saharan Africa than for Spanish women, and lower for Chinese women. Compared with Spanish women the odds of not breastfeeding in hospital were lower in all these immigrant groups but more than five times higher for Chinese immigrants. Culturally adapted health services are necessary to maintain breastfeeding rates in most immigrant groups. Moreover, it seems urgent to identify the factors influencing patterns of breastfeeding in Chinese immigrants and to develop innovative strategies to encourage breastfeeding initiation in hospital.

Calidad de los datos utilizados para el cálculo de indicadores de salud reproductiva y perinatal en población autóctona e inmigrante

OBJECTIVEnTo assess the quality of data on births in the Natural Population Movement (NPM) and congenital metabolic disorders registers with regard to calculation of reproductive and perinatal health indicators.nnnMETHODSnThe following comparisons between registers were made: (1) the total number of births to mothers living in Catalonia and Valencia from 2005 to 2006, (2) the percentage of missing data on the mothers geographical origin, (3) the percentage of missing data on the mothers age and the infants birthweight and gestational age according to maternal origin.nnnRESULTSnThe congenital metabolic disorders registers exhaustively collected the total number of births gathered in the NPM. The percentages of missing data on material origin and age were higher in the congenital metabolic disorders registers, although the proportion of births by maternal origin and the mean maternal age in each ethnic group was fairly similar to that in the NPM. The percentages of missing data on birthweight and gestational age were much higher in the NPM data than in the congenital metabolic disorders registers, especially among births registered in Catalonia and births to foreign mothers.nnnCONCLUSIONSnOur results suggest some limitations in the quality of the data on gestational age and birthweight provided by NPM data, especially for comparisons of preterm and low birthweight indicators in the Spanish-born and immigrant populations. Moreover, the results point to the quality of the congenital metabolic disorders registers as a source to compare reproductive and perinatal health indicators.

Shortening of gestational length among native-born and immigrants in Spain (1997–2008)

During the last decade there have been significant socio-demographic changes in Spain with potential impact on gestational length. The aim of the study was to describe the evolution of gestational age during 1997–2008, separately for native-born and immigrant population, in order to assess their contribution to the overall pattern of gestational length. A cross-sectional study of 5,018,229 singleton births born between 1997 and 2008 was carried out. The annual mean of gestational age was calculated and compared by means of ANOVA test, globally and also separately for natives and immigrants. Proportions of deliveries by gestational age and maternal characteristics were calculated in 4 periods and compared by means of Chi-square tests. Crude and adjusted multinomial logistic regression models were fitted separately for native-born and immigrant women. Our results show that in the last 12xa0years a progressive shortening in the mean gestational age has taken place in Spain. While the overall decrease of gestational length along the period was 1.5xa0days, closer to that in Spanish women (1.3xa0days), it was 2.3xa0days among immigrants. In both groups this shortening was mainly due to an increase in the proportion of 37–39xa0weeks deliveries at the expense of a substantial decrease in those with 40xa0weeks. These trends remained after controlling for known confounding variables such as maternal age, parity and occupation. Further analysis of its causes and public health implications are recommended.

Adverse birth outcomes in the vicinity of industrial installations in Spain 2004-2008

Industrial activity is one of the main sources of ambient pollution in developed countries. However, research analyzing its effect on birth outcomes is inconclusive. We analyzed the association between proximity of mother’s municipality of residence to industries from 24 different activity groups and risk of very (VPTB) and moderate (MPTB) preterm birth, very (VLBW) and moderate (MLBW) low birth weight, and small for gestational age (SGA) in Spain, 2004–2008. An ecological study was defined, and a “near vs. far” analysis (3.5xa0km threshold) was carried out using Hierarchical Bayesian models implemented via Integrated Nested Laplace Approximation. VPTB risk was higher for mothers living near pharmaceutical companies. Proximity to galvanization and hazardous waste management industries increased the risk of MPTB. Risk of VLBW was higher for mothers residing near pharmaceutical and non-hazardous or animal waste management industries. For MLBW many associations were found, being notable the proximity to mining, biocides and animal waste management plants. The strongest association for SGA was found with proximity to management animal waste plants. These results highlight the importance of further research on the relationship between proximity to industrial sites and the occurrence of adverse birth outcomes especially for the case of pharmaceutical and animal waste management activities.

Quality of data used to calculate reproductive and perinatal health indicators in native and migrant populations

OBJECTIVE To assess the quality of data on births in the Natural Population Movement (NPM) and congenital metabolic disorders registers with regard to calculation of reproductive and perinatal health indicators. METHODS The following comparisons between registers were made: (1) the total number of births to mothers living in Catalonia and Valencia from 2005 to 2006, (2) the percentage of missing data on the mothers geographical origin, (3) the percentage of missing data on the mothers age and the infants birthweight and gestational age according to maternal origin. RESULTS The congenital metabolic disorders registers exhaustively collected the total number of births gathered in the NPM. The percentages of missing data on material origin and age were higher in the congenital metabolic disorders registers, although the proportion of births by maternal origin and the mean maternal age in each ethnic group was fairly similar to that in the NPM. The percentages of missing data on birthweight and gestational age were much higher in the NPM data than in the congenital metabolic disorders registers, especially among births registered in Catalonia and births to foreign mothers. CONCLUSIONS Our results suggest some limitations in the quality of the data on gestational age and birthweight provided by NPM data, especially for comparisons of preterm and low birthweight indicators in the Spanish-born and immigrant populations. Moreover, the results point to the quality of the congenital metabolic disorders registers as a source to compare reproductive and perinatal health indicators.

Natural conception in HIV-serodiscordant couples with the infected partner in suppressive antiretroviral therapy: A prospective cohort study.

AbstractThe potential of antiretroviral treatment (ART) to prevent the sexual transmission of HIV has increased the number of serodiscordant couples who are considering natural conception. We aim to describe the results of a protocol for reproductive counseling aimed at HIV serodiscordant couples who desire natural conception, in which the infected partner, the index case, is receiving suppressive antiretroviral treatment.A prospective cohort included all HIV serodiscordant couples attended a counseling program in the period 2002 to 2013 who opted for natural conception and met the following criteria: index case on ART with persistent plasma viral suppression for at least the previous 6 months, ART compliance over 95%, preserved immune status, undetectable HIV viral and proviral load in semen in male index cases, and absence of genitourinary infections and fertility problems in both members of the couple.Of the 161 HIV serodiscordant couples included, 133 with male index cases, 66% achieved at least 1 pregnancy, 18% a second one, and 5% a third pregnancy. A total of 144 natural pregnancies occurred and 107 babies were born. The pregnancy rate was 1.9 for each 100 acts of vaginal intercourse, and the mean time to conception was 6.1 months, both independently of the sex of the index case. No case of sexual or vertical HIV transmission occurred.In the absence of fertility problems and under controlled conditions, natural conception might be a safe and effective reproductive method for those HIV serodiscordant couples who choose this reproductive option.
