Migration background: a risk factor for caries development during adolescence

Caries Decline in Preschool Children from Low Social Classes and with Migration Background in Hamburg, Germany: Outcome from Repeated Cross-Sectional Caries Epidemiological Studies

Over several decades, the dental caries burden in the deciduous dentition has decreased in Germany. However, a dependency of the caries burden on social parameters, such as socio-economic status (SES) or migration background, is generally described. Therefore, the aim of the evaluation was to analyse to what extent children with a low social class affiliation or a migration background have participated in the caries decline. For the city of Hamburg, Germany, data from a series of five caries epidemiological surveys in day-care centres are available since 1977. Using the same methodology, the dmft values were determined, according to WHO criteria, and in addition including initial caries (IC). For the present evaluation, the data and the changes of caries load (caries prevalence and caries experience; dmft) over time were compared with reference to SES and a migration background. A decrease in the caries prevalence from 58.4% to 22.7% and in the dmft value from 2.6 to 0.8 was determined from 1977 to 2016 (WHO criteria). Including IC, the caries prevalence has decreased from 91.0% to 44.4%, and the caries experience shows a decline from 6.4 to 1.8. The caries reduction can be observed in children of all social classes and regardless of a migration background, although significant differences in caries prevalence and caries experience remain recognisable for each survey through 2016. In conclusion, preschool children from families with low SES or with a migration background have not been left behind in the improvement of dental health, but have also benefited from caries prevention measures in roughly the same order of magnitude as other children.

Birth and Health Outcomes of Children Migrating With Parents: A Systematic Review and Meta-Analysis

Objective

To examine the birth and health outcomes of children migrating with parents internationally and domestically, and to identify whether the healthy migration effect exist in migrant children.

Methods

Five electronic databases were searched for cross-sectional, case-control, or cohort studies published from January 1, 2000 to January 30, 2021and written by English language, reporting the risk of health outcomes of migrant children (e.g., birth outcome, nutrition, physical health, mental health, death, and substance use) We excluded studies in which participants' age more than 18 years, or participants were forced migration due to armed conflict or disasters, or when the comparators were not native-born residents. Pooled odd ratio (OR) was calculated using random-effects models.

Results

Our research identified 10,404 records, of which 98 studies were retrained for analysis. The majority of the included studies (89, 91%) focused on international migration and 9 (9%) on migration within country. Compared with native children, migrant children had increased risks of malnutrition [OR 1.26 (95% CI 1.11-1.44)], poor physical health [OR 1.34 (95% CI 1.11-1.61)], mental disorder [OR 1.24 (95% CI 1.00-1.52)], and death [OR 1.11 (95% CI 1.01-1.21)], while had a lower risk of adverse birth outcome [OR 0.92 (95% CI 0.87-0.97)]. The difference of substance use risk was not found between the two groups.

Conclusion

Migrant children had increased risk of adverse health outcomes. No obvious evidence was observed regarding healthy migration effect among migrant children. Actions are required to address the health inequity among these populations.

Access Barriers to Dental Treatment and Prevention for Turkish Migrants in Germany – A Qualitative Survey

Introduction

The worldwide migration movement is growing and thereby challenging the health care systems of immigration countries like Germany to make health care equally accessible for all people. Due to their low oral health status and low uptake rates of dental treatment and prevention, migrants were detected as a vulnerable group. Data regarding dental care access barriers of this group is limited. Therefore, the following study established a deeper understanding of unknown access barriers.

Methods

Nine expert interviews and one focus group interview were conducted semi-structured via interview guideline in the period of August until October 2018. The experts were persons with strong vocational interactions and experiences with the sector oral health care and migration. The focus group participants had a Turkish migration background.

Results

The expert and focus group interviews revealed a variety of barriers that exist toward dental treatment and prevention for migrants. Language, perceived significance of oral health, oral health knowledge, health socialization and patient-dentist interaction were detected to be the main barriers with underlying subthemes and interactions. Furthermore, a predominantly not precaution-oriented dental service utilization of migrants was underlined by the interviewees. Additionally, ways to reach a higher cultural sensitivity in oral health care were stated.

Conclusion

With respect for research, there is a need for the integration of migrant-specific items when collecting health data from people. With respect for policy, there is a need for more structural and individual attention for promoting equal access to oral health care and prevention measures for people with a migrant background.

Dental Caries Prevalence and Experience (ICDAS II Criteria) of 5-, 12- and 15-Year-Old Children and Adolescents with an Immigrant Background in Greece, Compared with the Host Population: A Cross-Sectional Study

Evidence regarding disparities in oral health among native and immigrant child and adolescent populations in Europe is scarce. The present study aimed to determine the caries status of 5-, 12-, and 15-year-olds with an immigrant background in Greece in relation to their sociodemographic characteristics and compare their caries levels with those of their native Greek peers. A sample of 707 immigrants underwent clinical examination for caries (ICDAS II criteria), followed by a calculation of caries prevalence and experience estimates (2013-2014). Multivariable regression models assessed the effect of ethnic background on the caries experience (d_3-6mfs/D_3-6MFS) of the total (707 immigrants and 3702 Greeks) population, and the association between parental education level and the immigrants' d_3-6mfs/D_3-6MFS. Among the 5- and 12-year-olds, those with an immigrant background demonstrated higher caries rates and had unfulfilled treatment needs at higher proportions. Among 15-year-old adolescents, no considerable differences in caries status were observed according to ethnic background (native Greek or immigrant). The strength of the association between immigrant background and caries experience levels attenuated gradually with increasing age (IRR = 1.61, 1.27 and 1.10, and p = 0.001, p = 0.006 and p = 0.331 for 5-, 12- and 15-year-olds, respectively). Among the immigrants, adolescents with less educated mothers exhibited elevated caries levels. Public health strategies should prioritize immigrant children and early adolescents in order to reduce the existing ethnic disparities in oral health.

Oral Health Status among Migrants from Middle- and Low-Income Countries to Europe: A Systematic Review

Introduction. Economic inequality, political instability and globalization have contributed to the constant growth of the migration phenomenon in recent years. In particular, a total of 4.2 million people migrated to Europe during 2019 and most of them settled in Germany, France and Italy. Objectives. The objective of this study was to conduct a systematic review of studies analyzing the oral health condition among migrants from middle- and low-income countries to Europe and assessing the eventual association between their sociodemographic and socioeconomic characteristics and oral health status. Materials and Methods. A systematic review was conducted in PubMed, Cochrane Library, Scopus and Science Direct databases. After titles, abstracts and full-text examination, only 27 articles were selected on the basis of inclusion criteria and consequently included for quality assessments and data extraction. Results. Most of the studies reported a higher prevalence of caries experience, a poorer periodontal health and more difficulties in accessing dentalcare services among migrant groups compared with the non-migrant population. Inequalities were mostly associated with ethnic background, economic condition and social grade. Conclusion. Our review demonstrates the lack of dental health among migrants, underlining that their cultural beliefs and their social and economic living conditions could influence their oral health.

[Oral health literacy of persons with migration background-first results of the MuMi study]

BACKGROUND

First investigations indicate a migration background of residents in Germany as a discrete risk factor for poor oral health. A lower level of oral health literacy among people with a migration background is considered a reason worthy of being investigated.

AIM

This article presents results on oral health literacy and oral health gained from the MuMi study (promoting oral health and oral health literacy of people with a migration background).

METHODS

The oral health and oral health literacy as well as the sociodemographics of patients with and without migration background were examined in 40 dental surgeries in Hamburg, Germany. Associations between migrant status, oral health, and oral health literacy were analyzed with logistic regressions. Potential confounders were gradually integrated into the multivariate analyses.

RESULTS

Patients with and without a migration background differed significantly in oral health literacy and clinical parameters of oral health (approximal plaque index and degree of caries restoration). The logistic regression analysis revealed highly significant associations between migration background, oral health literacy, and oral hygiene, while also accounting for education and socioeconomic status.

DISCUSSION

Migration background constitutes a discrete risk factor for lower oral health and oral health literacy for these relevant population groups. This fact needs stronger reflection in further research and political decision-making in order to promote equality of oral health opportunities.

Development level of the country of parental origin on dental caries in children of immigrant parents in Sweden

AIM

To study the association of parental country of origin-expressed as low-, medium- and high-Human Development Index (HDI) countries-with caries experience in children of immigrant families in Stockholm.

METHODS

This registry-based cohort study included all children born in 2000-2003 who resided in Stockholm County, Sweden, at age 3 years (n = 83,147) with follow-up at 7 years of age. A logistic regression was performed for the multivariate analysis with adjustments for socio-demographic factors.

RESULTS

After adjustments, logistic regression analyses revealed that, compared with Swedish children of the same age, the risk of caries was highest when the immigrant parents originated in a medium (OR 4.22 (95% CI 3.99:4.47)) or low (OR 2.80 (95% CI 2.56:3.06)) income country background at age 7 years, but was increased also for high-income country background, OR 1.77 (95% CI 1.52-2.05). Furthermore, the risk of presenting with caries experience at age 7 years increased for all children in the 1^st (lowest) household income quintile in the host country Sweden.

CONCLUSION

This study shows that the developmental level of the parental country of birth as well as the family socioeconomic position in Sweden influence the risk for caries development in their children.

Impact of Lifestyle Variables on Oral Diseases and Oral Health-Related Quality of Life in Children of Milan (Italy)

A large part of the Italian population doesn’t receive adequate information and support on how to maintain oral health. In this observational, cross-sectional, pilot study, we investigated how some lifestyle-related variables affect oral diseases and oral health-related quality of life (OHRQoL) of children attending public-school summer services in Milan. A survey that included questions on children’s oral disease, OHRQoL and lifestyle-related factors (feeding habits, oral hygiene protective behaviors, dental coaching and socio-economic and educational status), was administered to the children’s caregivers. Data from 296 surveys were analyzed to assess the protective/negative effect of each variable on oral disease and OHRQoL. With respect to disease, the “never” consumption of fruit juice, the use of fluoride toothpaste, higher educational qualification and ISEE (equivalent family income) of those who filled out the form, resulted protective factors. Regarding OHRQoL, the “never” assumption/use of tea bottle, sugared pacifier and fruit juice as well as the use of fluoride toothpaste, a higher educational qualification and ISEE of those who filled out the form, resulted to have protective effects. In conclusion, protective behaviors and socio-economic status affect oral disease and OHRQoL in children of Milan.

Understanding behavioural changes through community-based participatory research to promote oral health in socially disadvantaged neighbourhoods in Southern Sweden

OBJECTIVES

Inequalities in oral health have been on the rise globally. In Sweden, these differences exist not between regions, but among subgroups living in vulnerable situations. This study aims at understanding behavioural change after taking part in participatory oral health promotional activity among families living in socially disadvantaged neighbourhoods in Southern Sweden.

SETTING

The current study involved citizens from a socially disadvantaged neighbourhood in Malmö, together with actors from the academic, public and private sectors. These neighbourhoods were characterised by high rates of unemployment, crime, low education levels and, most importantly, poor health.

PARTICIPANTS

Families with children aged 7-14 years from the neighbourhood were invited to participate in the health promotional activities by a community representative, known as a health promoter, using snowball sampling. Between 8 and 12 families participated in the multistage focus groups over 6 months. Data were analysed using qualitative content analysis.

RESULTS

Three main themes emerged from the analysis, providing an understanding of the determinants for behavioural change, including meaningful social interactions, family dynamics and health trajectories. The mothers in the study valued the social aspects of their participation; however, they believed that gaining knowledge in combination with social interaction made their presence also meaningful. Further, the participants recognised the role of family dynamics primarily the interactions within the family, family structure and traditional practices as influencing oral health-related behaviour among children. Participants reported having experienced a change in general health owing to changed behaviour. They started to understand the association between general health and oral health that further motivated them to follow healthier behavioural routines.

CONCLUSIONS

The results from this study show that oral health promotion through reflection and dialogue with the communities, together with other stakeholders, may have the potential to influence behavioural change and empower participants to be future ambassadors for change.

Health Care Needs in School-Age Refugee Children

Most European countries have systematic health assessments of refugees with a main focus on infectious diseases. The aim of this study was to describe the broader health care needs identified in newly settled refugee children in a school health setting. The study population consisted of all 609 recently settled Non-European refugee and asylum-seeking children in the age range 6-15 years who were enrolled in the schools of Malmö, Sweden during the autumn semester of 2015, of which 265 had arrived in Sweden unaccompanied. The data were collected in a structured routine intake interview by an experienced school nurse. Almost half of the children had obvious untreated caries. For the unaccompanied children, prominent mental health needs were present in almost one in three. Previously unidentified vision and/or hearing problems were identified in one in ten and around 5% had a daily medication, and 4.5% of the unaccompanied children and 1.2% of the accompanied children were judged to be in need of immediate care and were referred accordingly. Newly settled refugee children in northern Europe have considerable health care needs apart from communicable diseases. School health services have a unique platform to identify and initiate this care.

Acculturation and Dental Caries Among Children in Spain

This study explored the relationship between different indicators of acculturation and children's caries experience. Data from 313 children attending the Dental Clinic of the European University of Madrid were analysed. Acculturation was measured via generational status, age at arrival, length of residence and language spoken at home. The association between each indicator of acculturation and caries experience was assessed in Poisson regression models adjusting for confounders. First- and second-generation migrant children had greater caries experience than Spanish-born children. These differences only persisted for first-generation migrant children after adjustment for confounders. Children who arrived in Spain before age 6 years, who lived in Spain for 10 or more years and who spoke a language other than Spanish at home had greater caries experience than Spanish-born children. Inequalities in caries experience between migrant and native children were evident (favouring the local children) and independent of family's socioeconomic circumstances.

Multiple Socioeconomic Factors and Dental Caries in Swedish Children and Adolescents

The study aimed to explore associations between multiple socioeconomic factors and dental caries experience in Swedish children and adolescents (3-19 years old). Electronic dental records from 300,988, in a Swedish region (97.3% coverage) were collected using the DMFT indices (decayed, missing, filled teeth: dependent variables). Socioeconomic status (SES) data (ethnicity, wealth, parental education, and employment) for individuals, parents, and families were obtained from official registers. Principal component analysis was used to explore SES data. Scores based on the first factor were used as an independent aggregated socioeconomic variable in logistic regression analyses. Dental caries experience was low in the participants: 16% in 3- to 6-year-olds (deft index: decayed, extracted, filled teeth) and 47% in 7- to 19-year-olds (DFT index). Both separate and aggregated socioeconomic variables were consistently associated with the dental caries experience irrespective of the caries index used: the crude odds ratio (OR) for having at least 1 caries lesion in 3- to 6-year-olds (deft index) in the lowest SES quintile was 3.26 (95% confidence interval [CI] 3.09-3.43) and in ≥7-year-olds (DFT index) OR 1.80 (95% CI 1.75-1.84) compared with children in the 4 higher SES quintiles. Overall, associations were stronger in the primary dentition than in the permanent dentition. Large SES models contributed more to explaining the caries experience than slim models including fewer SES indicators. In conclusion, socioeconomic factors were consistently associated with dental caries experience in the children and adolescents both as single factors and as multiple factors combined in an index. Socioeconomic inequalities had stronger associations to caries experience in young children than in older children and adolescents.

Behavioural characteristics in externalising children with low and elevated risk for dental caries

Aim

To compare two groups of children with externalising behaviour problems, having low and elevated caries risk, respectively. Those parameters were assessed in relation to behavioural characteristics and family structure, and to compare the caries risk assessment and gender differences in relation to children in general in the Region of Västra Götaland, Sweden.

Methods

Families (228) with children, aged 10-13 years, participating in parent training programmes, were recruited. Parents provided information through questionnaires regarding parental knowledge and monitoring, family warmth and conflict and family structure. Children’s behavioural characteristics, based on the Strength and Difficulties Questionnaire and the Disruptive Behaviour Disorder rating scale, were used as outcome. Data about caries risk assessment were obtained from dental records.

Results

Children in the elevated caries risk group showed higher mean values for conduct problems as well as impulsivity. Parents of the children in the elevated caries risk group reported more parental solicitation and less family conflicts. Children with an elevated caries risk lived more often in households with more than two children and had more often a father from a non-Nordic country.

Conclusion

There were statistically significant more children with an elevated caries risk in the study group compared to children in general in the Region of Västra Götaland, both totally and within gender. Differences were observed with regard to behavioural characteristics in externalising children with an elevated risk for caries. Increased knowledge regarding behavioural characteristics in externalising children is an important parameter to be considered in caries risk assessment.

Oral Healthcare Implications of Mass Migration

Population movements, whether voluntary or forced, are an integral part of an increasingly globalized society and, while the health needs of migrant populations cannot be generalized, some migrants can have worse oral health outcomes compared with their host-country counterparts, with their first dental contact typically being for emergency care. Failure to provide immediately necessary treatment may be unlawful under the Human Rights Act 1998. CPD/Clinical Relevance: NHS dental services need to evolve and address the challenges inherent in caring for vulnerable migrants. Education and appropriate training needs to be developed for the dental profession in order to enable new ways of promoting intersectoral care and community engagement.

Migration background is associated with caries in Viennese school children, even if parents have received a higher education

Background

A low level of education and the migration background of parents are associated with the development of caries in children. The aim of this study was to evaluate whether a higher educational level of parents can overcome risks for the development of caries in immigrants in Vienna, Austria.

Methods

The educational level of the parents, the school type, and the caries status of 736 randomly selected twelve-year-old children with and without migration background was determined in this cross sectional study. In children attending school in Vienna the decayed, missing, and filled teeth (DMFT) index was determined. For statistical analysis, a mixed negative-binomial-model was used.

Results

The caries status of the children with migration background was significantly worse compared to that of the native Viennese population. A significant interaction was found between migration background and the educational level of the parents (p = 0.045). No interaction was found between the school type and either the migration background (p = 0.220) or the education level of the parents (p = 0.08). In parents with a higher scholarly education level, migration background (p < 0.01) and school type (p = 0.018) showed an association with DMFT values. In parents with a low education level, however, migration background and school type had no significant association with DMFT values.

Conclusion

These data indicate that children with a migration background are at higher risk to acquire caries than other Viennese children, even when the parents have received a higher education.

Is congenital malformation a risk factor for caries development in Swedish adolescents?

OBJECTIVE

The aim of this study was to investigate whether various forms of congenital malformations are risk factors for approximal caries development in Swedish adolescents.

MATERIALS AND METHODS

This longitudinal register-based cohort study included all adolescents (n = 18 142) of 13 years of age who resided in the county of Stockholm, Sweden, in 2000. The cohort was followed until individuals were 19 years of age. Dental caries (decayed, missing and filled teeth/surfaces (DMFT/S)) were collected from the Public Health Care Administration in Stockholm. Data concerning pre- and perinatal factors and parental socio-demographic determinants were collected from Swedish National Registers.

RESULTS

In a logistic regression analysis, neither congenital malformation nor any sub-group of congenital malformation registered at birth were significantly associated with an enhanced risk of approximal caries increment in adolescents between 13-19 years of age. The final multivariate logistic regression model, adjusted for possible maternal and family socio-demographic confounders, showed that congenital malformation of the 'circulatory system' was significantly associated with a decreased risk of approximal caries increment, between 13-19 years of age (OR = 0.33; 95% CI = 0.12-0.88).

CONCLUSIONS

Congenital malformation should not be considered as a risk factor for approximal caries development in Swedish adolescents today. Noticeably, adolescents with congenital heart diseases exhibited less risk of developing approximal caries, which was probably related to prevention programs allocated to these children in Sweden.

Oral health in young individuals with foreign and Swedish backgrounds--a ten-year perspective

AIM

To investigate oral health status and coherent determinants in children with foreign backgrounds compared with children with a Swedish background, during a ten year period.

DESIGN AND METHODS

In 1993 and 2003, cross-sectional studies with random samples of individuals in the age groups 3, 5, 10 and 15 years were performed in Jönköping, Sweden. All the individuals were personally invited to a clinical and radiographic examination of their oral health status. They were also asked about their attitudes to and knowledge of teeth and oral health care habits. The final study sample comprised 739 children and adolescents, 154 with a foreign background (F cohort) and 585 with a Swedish background (S cohort).

RESULTS

In both 1993 and 2003, more 3- and 5 year olds in the S cohort were caries-free compared with the F cohort. In 1993, dfs was higher among 3- and 5 year olds in the F cohort (p<0.01) compared with the S cohort. In 2003, dfs/DFS was statistically significantly higher in all age groups among children and adolescents in the F cohort compared with the S cohort. When it came to proximal tooth surfaces, the percentages of individuals who were caries-free, with initial carious lesions, with manifest carious lesions and with restorations among 10-year-olds in the F cohort were 55%, 23%, 4% and 18% in 1993. The corresponding figures for the S cohort were 69%, 20%, 6% and 5% respectively. In 2003, the values for the F cohort were 54%, 29%, 4% and 13% compared with 82%, 12%, 1% and 5% in the S cohort. In 2003, the odds of being exposed to dental caries among 10- and 15-yearolds in the F cohort, adjusted for gender and age, were more than six times higher (OR=6.3, 95% CI:2.51-15.61; p<0.001) compared with the S cohort.

CONCLUSIONS

There has been a decline in caries prevalence between 1993 and 2003 in all age groups apart from 3-year-olds. However, the improvement in dfs/DFS was greater in the S cohort compared with the F cohort in all age groups. The difference between the F and S cohorts in terms of dfs/ DFS was larger in 2003 compared with 10 years earlier. In 2003, the odds ratio for being exposed to dental caries was almost six times higher for 10- and 15-year-olds with two foreign-born parents compared with their Swedish counterparts.
