Couple partnership and divorce in domestic and non-European international adoptees. A Swedish national cohort study with follow up until 36 to 45 years
Adoption research shows a growing interest in adopted persons in their adult years. This article examines couple partnerships and divorce among adult adoptees and non-adoptees. Using population-based Swedish register data with follow-up until age 36-45 years, domestic and international adoptees were compared with the general population, as well as with immigrants who settled in Sweden in their early years and share with international adoptees a n…
Mental Health in Schoolchildren in Joint Physical Custody
This study investigated mental health in schoolchildren in different living arrangements after parental separation. The study population included 31,519 children from the Danish National Birth Cohort, followed-up at age 11 in 2010-2014. Child mental health was measured with a maternal report of the Strength and Difficulties Questionnaire (SDQ). Associations between living arrangements and mental health were analyzed using logistic and linear regr…
Birth order is associated with caries development in young children
These findings show that birth order influences caries development in siblings, suggesting that birth order can be regarded as a predictor for caries development in young children. This factor may be helpful in assessing caries risk in preschool children and should be considered in caries prevention work in young children with older siblings
Living situations among undocumented migrants in Sweden
Today, there is limited knowledge about the living conditions of undocumented migrants (UMs) in Sweden. It is hypothesised that Ums’ living conditions increases cases of mental illness among them. The aim of this study was twofold, to explore: the housing situation of UMs in Sweden, and its association to their state of mental health. A cross‐sectional study with adult UMs was conducted in the three largest cities in Sweden in 2014–2016. A total …
Acculturation or unequal assimilation? Smoking during pregnancy and duration of residence among migrants in Sweden
A growing corpus of evidence reveals that smoking patterns of migrant women tend to converge with that of the host population over time ('acculturation paradox'). In this paper we aim to adopt a health equity perspective by studying the extent to which this pattern reflects a convergence with the group of natives who are more socioeconomically disadvantaged. Using population-based registers, we study 1,194,296 women who gave birth in Sweden betwe…
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…
The Effect of Rotavirus Vaccine on Socioeconomic Differentials of Paediatric Care Due to Gastroenteritis in Swedish Infants

Aim : To study the effect of a free rotavirus vaccine programme on hospital care for viral gastroenteritis. Method : A register-based national cohort study of paediatric in- and outpatient care for viral gastroenteritis in children Results : Reductions of 37% and 24% for inpatient care, and 11 % and 21% for outpatient care for viral ga…
What Can We Say Regarding Shared Parenting Arrangements for Swedish Children
Joint physical custody (JPC) refers to children living alternatively and about equally with both parents after a parental separation or divorce. The practice has been debated in relation to child well-being because of the frequent moves imposed on children and the potential stress from living in 2 homes. This study describes the background to the high frequency of Swedish children in JPC and the results from research on Swedish children’s well-be…
School Contextual Features of Social Disorder and Mental Health Complaints—A Multilevel Analysis of Swedish Sixth-Grade Students
This study addressed school-contextual features of social disorder in relation to sixth-grade students' experiences of bullying victimization and mental health complaints. It investigated, firstly, whether the school's concentrations of behavioural problems were associated with individual students' likelihood of being bullied, and secondly, whether the school's concentrations of behavioural problems and bullying victimization predicted students' …
Undocumented adult migrants in Sweden
The psychosocial situation among UMs in Sweden, in addition to insecure living conditions without a guarantee of basic needs being met is stressful, and many UMs live in constant fear of disclosure and deportation, all of which has a detrimental effect of the mental health. It is important to understand both associated risk factors for ill-health and coping strategies in this vulnerable population in order try to reduce ongoing stress
Dental healthcare utilisation among young adults who were in societal out‐of‐home care as children
We used Swedish national registers to analyse dental health care among young adults with childhood experience of out‐of‐home care (OHC), in Cox regression analyses. All 1.7 million Swedish residents born in 1980–1994 were included, of whom 4% had been in OHC. The population was followed up in the Dental Health Register from age 20 to 29, during the period 2009–2014. We found that persons with short or long OHC experience made emergency dental car…

Gender aspects of health‐related quality of life of youth in secure residential care in Sweden
This study examined health‐related quality of life of youth in secure residential care employing a gender perspective. The KIDSCREEN‐52 questionnaire was administered to 91 youths (46 boys and 45 girls) aged 13–17, admitted to four secure residential units in southern Sweden, in connection with a medical examination. Results were compared with a national Swedish survey from 2009 of 86,000 youths aged 15–16 years old. In age‐adjusted analyses, you…
Health problems and healthcare needs among youth in Swedish secure residential care
International research has consistently reported that youth in secure residential care have high rates of somatic/dental health problems. Here, we report results from the first such study in a Nordic country. An experienced paediatrician performed systematic somatic and rudimentary dental health assessments of 91 youths, age 13–17, recently admitted to four secure residential units in Sweden. Girls were oversampled. Participants were tested for s…
Labour market participation among young refugees in Sweden and the potential of education
This register-based study examined the importance of education on labour market participation among young refugees in Sweden. The study population consisted of unaccompanied (n = 1606) and accompanied refuges (n = 4142), aged 23–26 years in 2006–2010, after 7 years of residence in Sweden. Native Swedish, aged 24 years (n = 347,255) constituted the comparison population, with intercountry adoptees (n = 6689) as an alternative reference group. Gend…
Childhood risk factors for disability pension among adult former Swedish child welfare clients
A decade lost
BACKGROUND: Past research has consistently identified children with out-of-home care (OHC) experience as a high-risk group for premature mortality. While many have argued that educational success is a key factor in reducing these individuals' excessive death risks, empirical evidence has hitherto been limited. The aim of the current study was therefore to examine the potentially mitigating role of educational success in the association between OH…
Avoidable mortality among parents whose children were placed in care in Sweden
BACKGROUND: Separation from one's child can have significant consequences for parental health and well-being. We aimed to investigate whether parents whose children were placed in care had higher rates of avoidable mortality. METHODS: Data were obtained from the Swedish national registers. Mortality rates among parents whose children were placed in care between 1990 and 2012 (17 503 mothers, 18 298 fathers) were compared with a 1:5 matched cohort…
Hospital admissions due to alcohol related disorders among young adult refugees who arrived in Sweden as teenagers – a national cohort study
Young refugees have lower risks of alcohol disorders compared with native Swedes. The risks were higher in unaccompanied young (male) refugees compared to the accompanied ones. Moreover, Somalian refugees who had lived in Sweden for more than ten years seems to be particularly vulnerable to alcohol related disorders
The Living Conditions of Children with Shared Residence – the Swedish Example
Among children with separated parents, shared residence – i.e., joint physical custody where the child is sharing his or her time equally between two custodial parents’ homes – is increasing in many Western countries and is particularly common in Sweden. The overall level of living among children in Sweden is high; however, the potential structural differences between children in various post-separation family arrangements have not been sufficien…
Childhood Adversities and Later Economic Hardship among Swedish Child Welfare Clients
National register data were used in a longitudinal design to test two competing hypotheses regarding links between cumulative exposure to childhood adversities and later adverse outcomes, conceptualised as economic hardship in early adulthood, among more than 11,000 Swedish youths who had received the same in-home child welfare intervention at ages two to five or at ages ten to thirteen. The cumulative-disadvantage perspective argues that the acc…
Challenges in administrative data linkage for research
Linkage of population-based administrative data is a valuable tool for combining detailed individual-level information from different sources for research. While not a substitute for classical studies based on primary data collection, analyses of linked administrative data can answer questions that require large sample sizes or detailed data on hard-to-reach populations, and generate evidence with a high level of external validity and applicabili…

Parental death during childhood and depression in young adults – a national cohort study
BACKGROUND: There are few prospective, population-based studies on childhood parental death and psychiatric disorders in adulthood, and previous findings are inconclusive. This study investigated the association between parental death from natural and external (suicides, accidents or homicides) causes before 18 years and the risk of clinical depression in young adults, in relation to age at loss and gender of both child and parent. METHODS: In th…
Why should they live more with one of us when they are children to us both
Joint physical custody, i.e., children spending an equal amount of time in both parents' home after a separation or divorce, is increasing in many countries. In line with the national policy to promote paternal involvement in parenting, two-thirds of Swedish preschoolers with non-cohabiting parents live in two homes. Internationally, there has been a debate regarding the benefits or risks with joint physical custody for infants and toddlers. The …
School performance in primary school and psychosocial problems in young adulthood among care leavers from long term foster care
Cognitive, educational and self-support outcomes of long-term foster care versus adoption. A Swedish national cohort study
The Epidemiology of Out-of-Home Care for Children and Youth
We used data from several national registers for fifteen entire cohorts (n > 1.5 million) of Swedish children and youth to examine the influence of parental socio-economic background on the risk of entry into out-of-home care. Logistic regression models were used to analyse the statistical impact of twelve background variables, including parental psycho-social risk markers. The results confirm and expand findings from a classic study by Bebbingto…

School performance at age 16 among international adoptees
School performance at age 16 for 6448 intercountry adoptees to Sweden was compared with that of siblings and majority population peers. The school performance of Korean-born adoptees was on a par with nonadopted peers, but non-Korean adoptees’ school performance was lower, as was that of adoptees who were older at the time of adoption
Risk factors for teenage childbirths among child welfare clients
This study contributes to the literature on preventing teenage childbirths by asking whether the pattern and strength of risk factors is the same for high-risk child welfare clients, as for their peers in the majority population. Longitudinal register data on more than 700,000 Swedish females, including around 29,000 child welfare clients, were analyzed by means of linear probability models and calculations of population attributable fractions. C…
Alcohol and drug abuse among young adults who grew up in substitute care — Findings from a Swedish national cohort study
To what extent substitute long term care modifies intergenerational transmission of substance abuse has rarely been investigated. Using register data, we followed a national cohort born 1973–1985 consisting of 1012 national adoptees, 2408 former children from long term foster care, 348/846 environmental siblings of adoptees/foster children, and 952,935 majority population peers, from their 15th birthday to age 27–35. Using Cox regression, we calc…
Disability pension among adult former child welfare clients
Using longitudinal register data on all persons born in Sweden 1973–1978, we report on prevalence of disability pension among young adults who were child welfare clients during their formative years, and explore risk factors for this long-term outcome. For most child welfare subgroups, prevalence approached or exceeded ten percent. Multivariate logistic regression analyses found high crude odds ratios of disability pension among child welfare alu…

Perceptions of usage and unintended consequences of provision of ready-to-use therapeutic food for management of severe acute child malnutrition. A qualitative study in Southern Ethiopia
BACKGROUND: Severe acute child malnutrition (SAM) is associated with high risk of mortality. To increase programme effectiveness in management of SAM, community-based management of acute malnutrition (CMAM) programme that treats SAM using ready-to-use-therapeutic foods (RUTF) has been scaled-up and integrated into existing government health systems. The study aimed to examine caregivers' and health workers perceptions of usages of RUTF in a chron…
The neighbourhood they live in—Does it matter to women's smoking habits during pregnancy
Fifty moves a year
BACKGROUND: In many Western countries, an increasing number of children with separated parents have joint physical custody, that is, live equally much in their parent's respective homes. In Sweden, joint physical custody is particularly common and concerns between 30% and 40% of the children with separated parents. It has been hypothesised that the frequent moves and lack of stability in parenting may be stressful for these children. METHODS: We …
School grades, parental education and suicide—a national register-based cohort study
BACKGROUND: To investigate whether school performance is a risk factor for suicide death later in life and, if so, to what extent this is explained by intergenerational effects of parental education. METHODS: This population-based cohort study comprises national birth cohorts between 1972 and 1981 in Sweden. We followed 898,342 students, graduating between 1988 and 1997 from the 9 years of compulsory school, equivalent to junior high school, unti…
Educational attainment and cognitive competence in adopted men — A study of international and national adoptees, siblings and a general Swedish population
A decade lost
BACKGROUND: Past research has consistently identified children with out-of-home care (OHC) experience as a high-risk group for premature mortality. While many have argued that educational success is a key factor in reducing these individuals' excessive death risks, empirical evidence has hitherto been limited. The aim of the current study was therefore to examine the potentially mitigating role of educational success in the association between OH…
Effectiveness of Sweden’s Contact Family/Person Program for Older Children
Objectives: To estimate the impacts of Sweden’s Contact Family/Person Program (CFPP) for older children on participants’ long-term outcomes related to mental health problems, illicit drug use, public welfare receipt, placement in out-of-home care, educational achievement, and offending. Method: We analyzed longitudinal register data on more than 1,000,000 individuals born between 1973 and 1984, including 6,386 individuals who entered CFPP at 10–1…

Mortality statistics in immigrant research
BACKGROUND: It is difficult to carry out fair comparisons of the mortality of different ethnic groups in a population in register-based studies because sizeable numbers of immigrants who subsequently leave their new homeland fail to register this fact with the national registration authorities. In this article we present a method which attempts to address these problems. METHODS: Age-standardized mortality rates for native Swedes and immigrants i…
Dental Health and Access to Dental Care for Ethnic Minorities in Sweden
This study demonstrates that adults in minority populations in Sweden use less dental care despite having greater needs of dental treatment than the majority population. This inequity calls for action in health policy and preventive dental health programmes
High Use of Sedatives and Hypnotics in Ethnic Minorities in Sweden
The higher use of sedatives and hypnotics in relation to health in the minority samples in the present study indicates a differential treatment of minor psychiatric disorders of members of ethnic minorities in Swedish health services. Further studies that yield more qualitative data regarding the interaction of Swedish physicians with migrant patients are needed to explain these differences and to create a basis for intervention
Effects of war and organized violence on children
Data from 99 school-aged Bosnian refugee children living in Sweden were analyzed to reveal the patterns of war stress experienced and the relation between these stressors and current psychological problems. A significant pattern of associations emerged. When children had experienced much stress, talking about their experiences seemed to exacerbate their negative effects
