Influence of immigration and other factors on caries in 12- and 15-yr-old children.

2007

In recent years the Valencia region has undergone mass immigration, mainly of people from eastern Europe, North Africa, and Latin America. The objective of this study was to assess the effect of immigration on caries prevalence and experience in 12- and 15-yr-old children in the Valencia region, and to relate this to other socio-economic and oral hygiene-related variables. The data were obtained from the epidemiological study of oral health carried out in the Valencia Region in 2004. The study group comprised 478, 12-yr-old children and 401, 15-yr-old children. Immigration status, age, toothbrushing frequency, and intake of cariogenic foods between meals showed significant association in a …

Utilisation of psychosocial and informational services in immigrant and non-immigrant German cancer survivors

2014

Objective We examined psychosocial and informational services used by long-term survivors of breast, colon and prostate cancer in immigrants versus non-immigrants. Methods Patients were sampled from population-based cancer registries in Germany. They completed a questionnaire assessing immigration biography, service use and socio-demographic characteristics. Results Data of 6143 cancer survivors were collected of whom 383 (6%) were immigrants. There was no evidence of an association between immigration status and service use. However, immigration biography played a role when patients' and their parents' birthplace were taken into account. When parents were born outside Europe, survivors les…

Acculturation and oral health status among Tibetan immigrants residing in Bangalore City, India

2011

Background: This study is the first of its kind conducted among Tibetans immigrants to Bangalore City, India to study the effects of acculturation on the oral health outcomes of less established group of individuals. Objectives: To determine the Acculturation and oral health status among Tibetan immigrants in Bangalore city and to assess the relationship between them. Materials and Methods: A random sample of 560 immigrants aged 18 years and above from different Tibetan centre of Bangalore city were included for the study. Acculturation was measured using modified Psychological-behavioral acculturation scale. Dental caries experience and periodontal status were recorded. Results: 49.1% of f…

Changes in smoking prevalence among first- and second-generation Turkish migrants in Germany – an analysis of the 2005 Microcensus

2009

Abstract Background Compared to the majority population of a host country, migrants tend to have different health risks and health behaviour. We have hypothesised that these differences diminish with time passed since migration. We tested this hypothesis by examining smoking behaviour among Turkish migrants and their children born in Germany (second-generation migrants), stratified by educational level and, for the first generation, length of residence. Methods We estimated the prevalence of smoking based on the representative 2005 Mikrozensus, an annual survey including 1% of Germany's households. The 2005 Microcensus was the first to provide information that makes it possible to different…

Effects of repeated short episodes of environmental acidification on Atlantic salmon (Salmo salar) from a landlocked population

2020

Abstract Chronic or repeated exposure to environmental contaminants may result in allostatic overload, a physiological situation in which the costs of coping affect long-term survival and reproductive output. Continuous measurements in Otra, the largest river in southern Norway, show the occurrence of repeated 24–48 h episodes of acidification. This work investigates the impact of repeated short acidification episodes on a unique land-locked population of normally anadromous Atlantic salmon (“Bleke”). This was done by recording physiological measures of stress and allostatic load in fish exposed for 7 days to continuous or repeated episodes of simulated environmental acidification or untrea…

Migrating neuroblasts of the rostral migratory stream are putative targets for the action of nitric oxide

2007

It has been demonstrated that the gaseous messenger nitric oxide influences cell proliferation and cell migration, and therefore affects adult neurogenesis in mammals. Here, we investigated the putative targets for this action in the rostral migratory stream of the rat. We used immunocytochemical detection of the beta1 subunit of the enzyme soluble guanylyl cyclase, which can be activated by nitric oxide. Our results under light and electron microscopy demonstrated that the migrating neuroblasts (type A cells) were beta1-immunopositive. The astrocytes (type B cells), immature precursors (type C cells) and ependymal cells (type E cells) were beta1-immunonegative. The neurochemical characteri…

Impact of climate change on migratory birds: community reassembly versus adaptation

2007

Aim Species can respond to global climate change by range shifts or by phenotypic adaptation. At the community level, range shifts lead to a turnover of species, i.e. community reassembly. In contrast, phenotypic adaptation allows species to persist in situ , conserving community composition. So far, community reassembly and adaptation have mostly been studied separately. In nature, however, both processes take place simultaneously. In migratory birds, climate change has been shown to result in both exchange of species and adaptation of migratory behaviour. The aim of our study is to predict the impact of global climate change on migratory bird communities and to assess the extent to which …

Spatial genetic structure reveals migration directionality in Mediterranean Ruppia spiralis (Western Sicily)

2022

Mediterranean salinas, originally built for salt production, function as alternative wetlands. A variety of accompanying lagoon, ditch, and marsh systems are suitable habitats for salt-tolerant submerged macrophytes and often characterized by monospecific beds of Ruppia. Traditionally, birds are considered the main dispersal vector of submerged macrophytes. However, Ruppia spiralis habitats are under marine influence and therefore interference of coastal currents in their connectivity might be expected. In this study, we aim to infer connectivity and spatial patterns from population genetic structures. Using nuclear microsatellite loci, the nuclear ribosomal cistron and chloroplast sequence…

The fertility of female immigrants to Europe from Christian and Muslim countries.

2020

Abstract This article investigates the fertility of female immigrants to Europe in relation to the characteristics of individual women (n=1,667), their countries of origin in Africa, Asia and Latin-America (n=68) and the European country where they reside (n=22), using the European Social Survey (ESS) collected between 2010 and 2017 (rounds 5 to 8). Many immigrants have fertility outcomes that converge towards the native fertility of their country of residence in Europe, a surprisingly strong factor. Immigrants from Muslim countries have higher fertility, though, and they compress their fertility over fewer years than immigrants from Christian countries. Multivariate estimates indicate that…
