Adolescent Health Inequality Across Immigrant Generations.

PURPOSE: Evidence on whether the immigrant health paradox (i.e., immigrants having better health than natives of nonmigrant background) extends to children and youth is mixed and often based on self-reported survey data. In this study, we use population-wide administrative microdata from Norwegian demographic and health registries to investigate health inequalities between adolescents with foreign-born and native-born parents, paying specific attention to variation across immigrant generations, origin countries, and types of diagnoses. METHODS: In this registry-based study, we estimate differences in the likelihood of somatic and mental disorders using logistic regression and population-wide health records for adolescents aged 16-20 years (N = 616,835). RESULTS: Child immigrants and native-born children of immigrants have fewer consultations for somatic and psychiatric diagnoses in adolescence compared to natives, while native-born children with mixed parental background have health outcomes more similar to natives. The differences are most pronounced for mental disorders. Differences across immigrant generations persist when stratifying by country of origin and when looking at specific diagnoses. DISCUSSION: The findings support the existence of an immigrant health advantage, which we find across various psychiatric and somatic diagnoses and for most immigrant generations. A key task for future research is to explore specific mechanisms underlying these patterns and to address potential inequities in the quality of health care provided to immigrant-background youth.

Educational achievement among children with a disability: do parental resources compensate for disadvantage?

We examined the impact of child disability on Grade Points Average (GPA) using all children aged 15-16 years who completed their lower secondary education and registered with a GPA score in the period from 2016 to 2020 in Norway (n = 247 120). We use registry data that contain information on the child's main diagnosis, such as physical-, neurological- and neurodevelopmental conditions, and the severity of the condition, additional to the child's family characteristics. First, we examined whether the impact of the child's disability on the GPA scores varied by diagnosis and the severity of the child's condition. Second, we examined whether higher parental socioeconomic status (SES) buffers against the negative impact of child disability on GPA scores. Using longitudinal register data with the school fixed-effect model, the results showed that children with neurological and neurodevelopmental disabilities obtained lower GPA scores than their typically developing peers without chronic conditions, however children with asthma and diabetes had comparable GPA scores. These associations were most evident for neurodevelopmental conditions, such as ADHD and autism but also notable for neurological conditions such as epilepsy. In general, a severe condition impacts GPA scores more negatively than a less severe condition. Moreover, our analysis revealed that children of highly educated parents obtained higher GPA scores than children who had parents with short education. This applied to both disabled and typically developing peers, except children with autism and epilepsy, among whom buffering due to the parent's education did not seem to apply.

Parental income gradients in child and adolescent mortality: Norwegian trends over half a century.

BACKGROUND: Child mortality has declined rapidly over the last century in many high-income countries. However, little is known about the socio-economic differences in this decline and whether these vary across causes of death. METHODS: We used register data that included all Norwegian births between 1968 and 2010 (2.1 million), and we analysed how all-cause and cause-specific child (0-4 years) and adolescent (5-20 years) mortality rates vary with relative parental income the year before the birth. RESULTS: Child and adolescent all-cause mortality decreased with increasing parental relative income within all birth cohorts. Among children aged 0-4 years, the socio-economic gradient in all-cause mortality and in mortality due to external causes, sudden infant deaths and perinatal factors declined over the period, while there was no systematic decline in mortality from congenital malformations. Among children aged 5-20 years, the gradient did not weaken similarly, although there were indications of declines in the socio-economic gradient related to all-cause deaths and deaths because of suicides and other external causes. While the absolute differences in mortality declined over time, the relative differences remained stable. CONCLUSIONS: Although children of low-income parents still have elevated mortality, there has been a large reduction in child mortality in all socio-economic groups across 50 years for all causes combined and most of the groups of specific causes of death.

Impact of the COVID-19 pandemic on mental healthcare consultations among children and adolescents in Norway: a nationwide registry study.

The COVID-19 pandemic and its associated restrictions may have affected children and adolescent's mental health adversely. We cast light on this question using primary and specialist consultations data for the entire population of children of age 6-19 years in Norway (N = 908 272). Our outcomes are the monthly likelihood of having a consultation or hospitalization related to mental health problems and common mental health diagnoses. We compared a pandemic (2019-2021) to a pre-pandemic (2017-2019) cohort using event study and difference-in-difference designs that separate the shock of the pandemic from linear period trends and seasonal variation. We found temporary reductions in all mental health consultations during lockdown in spring 2020. In fall 2020 and winter 2021, consultation volumes in primary care increased, stabilizing at a higher level in 2021. Consultations in specialist care increased from spring 2021. Our findings could suggest a worsening of mental health among adolescents.

Parental income gradients in adult health: a national cohort study.

BACKGROUND: Disparities in health by adult income are well documented, but we know less about the childhood origins of health inequalities, and it remains unclear how the shape of the gradient varies across health conditions. This study examined the association between parental income in childhood and several measures of morbidity in adulthood. METHODS: We used administrative data on seven complete Norwegian birth cohorts born in 1967-1973 (N = 429,886) to estimate the association between parental income from birth to age 18, obtained from tax records available from 1967, linked with administrative registries on health. Health measures, observed between ages 39 and 43, were taken from registry data on consultations at primary health care services based on diagnostic codes from the International Classification of Primary Care (ICPC-2) and hospitalizations and outpatient specialist consultations registered in the National Patient Registry (ICD-10). RESULTS: Low parental income during childhood was associated with a higher risk of being diagnosed with several chronic and pain-related disorders, as well as hospitalization, but not overall primary health care use. Absolute differences were largest for disorders related to musculoskeletal pain, injuries, and depression (7-9 percentage point difference). There were also differences for chronic disorders such as hypertension (8%, CI 7.9-8.5 versus 4%, CI 4.1-4.7) and diabetes (3.2%, CI 3.0-3.4 versus 1.4%, CI 1.2-1.6). There was no difference in consultations related to respiratory disorders (20.9%, CI 20.4-21.5 versus 19.7%, CI 19.2-20.3). Childhood characteristics (parental education, low birth weight, and parental marital status) and own adult characteristics (education and income) explained a large share of the association. CONCLUSIONS: Children growing up at the bottom of the parental income distribution, compared to children in the top of the income distribution, had a two- to threefold increase in somatic and psychological disorders measured in adulthood. This shows that health inequalities by socioeconomic family background persist in a Scandinavian welfare-state context with universal access to health care.

Parental income and mental disorders in children and adolescents: prospective register-based study.

BACKGROUND: Children with low-income parents have a higher risk of mental disorders, although it is unclear whether other parental characteristics or genetic confounding explain these associations and whether it is true for all mental disorders. METHODS: In this registry-based study of all children in Norway (n = 1 354 393) aged 5-17 years from 2008 to 2016, we examined whether parental income was associated with childhood diagnoses of mental disorders identified through national registries from primary healthcare, hospitalizations and specialist outpatient services. RESULTS: There were substantial differences in mental disorders by parental income, except for eating disorders in girls. In the bottom 1% of parental income, 16.9% [95% confidence interval (CI): 15.6, 18.3] of boys had a mental disorder compared with 4.1% (95% CI: 3.3, 4.8) in the top 1%. Among girls, there were 14.2% (95% CI: 12.9, 15.5) in the lowest, compared with 3.2% (95% CI: 2.5, 3.9) in the highest parental-income percentile. Differences were mainly attributable to attention-deficit hyperactivity disorder in boys and anxiety and depression in girls. There were more mental disorders in children whose parents had mental disorders or low education, or lived in separate households. Still, parental income remained associated with children's mental disorders after accounting for parents' mental disorders and other factors, and associations were also present among adopted children. CONCLUSIONS: Mental disorders were 3- to 4-fold more prevalent in children with parents in the lowest compared with the highest income percentiles. Parents' own mental disorders, other socio-demographic factors and genetic confounding did not fully explain these associations.

Impact of the COVID-19 pandemic on the treatment of injuries during lockdown in Norway.

AIMS: In order to prevent a major outbreak of COVID-19 disease in Norway, a series of lockdown measures was announced on 12 March 2020. The aim of the present paper was to describe the impact of this lockdown on the treatment of injuries. METHODS: We collected hospital data on injury diagnoses from a national emergency preparedness register established during the pandemic. We identified the number of injured patients per day in the period 1 January-30 June 2020, and analysed the change in patient volumes over two three-week periods before and during the lockdown by sex, age, level of care, level of urgency, type of contact and type of injury. RESULTS: Compared to pre-lockdown levels, there was an overall reduction of 43% in injured patients during the first three weeks of lockdown. The decrease in patient contacts did not differ by sex, but was most pronounced among young people. Substantial reductions were observed for both acute and elective treatment and across all levels of care and types of contact, with the exception of indirect patient contacts. The change in patient contacts varied considerably by injury type, with the largest reduction observed for dislocations/sprains/strains. The decrease was much lower for burns/corrosions and poisoning. CONCLUSIONS: A substantial reduction in the treatment of injuries was observed during lockdown in Norway. Possible explanations for this finding include an overall decrease in injury risk, a redistribution of hospital resources and a higher threshold for seeking medical attention as a result of the pandemic.

Mental health problems in adolescence, first births, and union formation: Evidence from the Young HUNT Study.

While a large literature documents how mental health problems in adolescence have long-term consequences for adult socioeconomic outcomes, less is known about the relation with family-formation behavior. In this paper, we use data from a population based Norwegian health survey (the Young-HUNT study) linked to administrative registry data (N = 8,113) to examine the long-term consequences of symptoms of internalizing and externalizing problems, the two most common forms of mental health problems, on family-formation outcomes: the likelihood of a first birth, the union status of a first birth, and entering first marriage. For men, externalizing problems are associated with earlier parenthood, especially becoming a father without having a coresidential relationship with the child's mother. Internalizing problems, on the other hand, are associated with lower first-birth rates and the association grows progressively stronger with age. We also find that the associations are more pronounced among men with low childhood socioeconomic status. In contrast, women's family-formation appears for the most part unrelated to their mental health.

Adolescent mental health and earnings inequalities in adulthood: evidence from the Young-HUNT Study.

BACKGROUND: Previous studies have shown that adolescent mental health problems are associated with lower employment probabilities and risk of unemployment. The evidence on how earnings are affected is much weaker, and few have addressed whether any association reflects unobserved characteristics and whether the consequences of mental health problems vary across the earnings distribution. METHODS: A population-based Norwegian health survey linked to administrative registry data (N=7885) was used to estimate how adolescents' mental health problems (separate indicators of internalising, conduct, and attention problems and total sum scores) affect earnings (≥30 years) in young adulthood. We used linear regression with fixed-effects models comparing either students within schools or siblings within families. Unconditional quantile regressions were used to explore differentials across the earnings distribution. RESULTS: Mental health problems in adolescence reduce average earnings in adulthood, and associations are robust to control for observed family background and school fixed effects. For some, but not all mental health problems, associations are also robust in sibling fixed-effects models, where all stable family factors are controlled. Further, we found much larger earnings loss below the 25th centile. CONCLUSIONS: Adolescent mental health problems reduce adult earnings, especially among individuals in the lower tail of the earnings distribution. Preventing mental health problems in adolescence may increase future earnings.
