The association between treated psychiatric and neurodevelopmental disorders and out-of-home care among Finnish children born in 1997

Annual Research Review: Psychosis in children and adolescents: key updates from the past 2 decades on psychotic disorders, psychotic experiences, and psychosis risk

Psychosis in children and adolescents has been studied on a spectrum from (common) psychotic experiences to (rare) early-onset schizophrenia spectrum disorders. This research review looks at the state-of-the-art for research across the psychosis spectrum, from evidence on psychotic experiences in community and clinical samples of children and adolescents to findings from psychosis risk syndrome research, to evidence on early-onset psychotic disorders. The review also looks at new opportunities to capture psychosis risk in childhood and adolescence, including opportunities for early intervention, identifies important unanswered questions, and points to future directions for prevention research.

Child- and parent-related determinants for out-of-home care in a nationwide population with neurodevelopmental disorders: a register-based Finnish birth cohort 1997 study

Neurodevelopmental disorders (NDDs) are among the most common health issues in childhood and adolescence. Psychiatric disorders are known to be overrepresented among children using child welfare services and placed in out-of-home care (OHC). Child- and parent-related determinants for OHC among a national population with NDDs were evaluated utilising longitudinal register data from the national Finnish Birth Cohort 1997 (n = 58,802) from birth to 18 years (1997-2015). The cohort members with NDDs (n = 5,143, 9% of total cohort) formed our study population. Based on their history of OHC, cohort members with NDD were categorised to OHC (n = 903) and non-OHC groups (n = 4,240). Of all cohort members with NDDs, 17.6% had a history of OHC. Within NDDs, a significant excess of ADHD diagnosis was observed in the OHC group compared to the non-OHC group (49% vs. 26%). The OHC group with NDDs was significantly characterised by having comorbid psychiatric diagnosis for conduct and oppositional disorders (adj. RR 2.21), substance use disorders (adj. RR 1.61) and depression and anxiety disorders (adj. RR 1.60). Of all parent-related determinants, the most prevailing in the OHC group compared to the non-OHC group, was social assistance received by parent (88% vs. 44.5%). The longer the period (in years) for received social assistance, the greater the likelihood for OHC (adj. RRs range from 2.41 for one year to 5.24 for over 4 years). Further, significantly associating determinants for OHC were parental psychiatric disorders (adj. RR 1.42) and parental death (adj. RR 1.23). Our findings from the population-based cohort of children and adolescents with NDDs highlight the importance of screening and assessment of family situation. Also, effective prevention and treating of comorbid psychiatric disorders, especially conduct and oppositional disorders is essential.

Mental health service use in children at risk of significant harm: A record linkage study of a child protection register

Children with experience of maltreatment, abuse or neglect have higher prevalence of poor mental health. In the United Kingdom, child protection services identify children at risk of significant harm on the Child Protection Register (CPR) and intervene to reduce risk. Prevalence and incidence of mental health service use among this population of children are not well understood. We analysed records from one Scottish Local Authority's CPR, linked to electronic health records for all children in the broader health board region aged 0-17 years. We described mental health service use among children with a CPR registration using measures of mental health prescribing and referrals to child and adolescent mental health services (CAMHS). We calculated age- and sex-specific incidence rates for comparison with the general population. Between 2012 and 2022, we found 1498 children with a CPR registration, with 69% successfully linked to their health records. 20% were registered before birth and median age at registration was 3 years. Incidence rates in all measures of mental health service use were higher in children with a CPR record across all ages (at outcome) and genders compared to the general population. The largest absolute difference was for boys aged 5-9 with a CPR record, who had 31.8 additional mental health prescriptions per 1000 person-years compared to the general population (50.4 vs. 18.6 prescriptions per 1000 person-years, IRR: 2.7). Girls aged 0-4 years with a CPR registration had the largest relative difference, with a rate of CAMHS referral 5.4 times higher than the general population (12.3 vs. 2.3 per 1000 person-years). Our reproducible record linkage of the CPR to health records reveals an increased risk of mental health service use during childhood. Our findings have relevance to public mental health surveillance, service prioritisation and wider policy aiming to reduce childhood exposure to risk of harm.

Temporal changes in the associations between diagnosed psychiatric disorders and dropping out of school early

Psychiatric problems are risk markers for poor educational attainment. The number of adolescents receiving treatment has increased. We investigated whether the association between psychiatric problems in early adolescence and dropping out of school had changed. We used the register-based 1987 and 1997 Finnish Birth Cohort studies, which include all live births in Finland. Hospital districts with incomplete records were excluded, leaving 25,421 participants born in 1987 and 32,025 born in 1997. The main outcome was not having applied for secondary education by the year the cohort members turned 18. Our main predictors were psychiatric and neurodevelopmental disorders diagnosed by specialized services during 1998-2003 and 2008-2013, when the cohort members were 10-16 years old. We found that 511 (2.0) of subjects born in 1987 and 499 (1.6%) born in 1997 dropped out of school. Having any diagnosis at 10-16 of age was associated with dropping out of school early in both cohorts: 3.9% in 1987 and 4.8% in 1997. The highest proportions were in the subgroup with autism spectrum disorders (ASD), 19.4% in 1987 and 16.2% in 1997. Dropping out early increased among adolescents diagnosed with any psychiatric or neurodevelopmental disorder, from 3.9 to 4.8%, with the clearest increase for learning disabilities, from 3.4 to 9.0%. Dropping out decreased for those with depression, from 4.5 to 2.1%. Adolescents with psychiatric and especially neurodevelopmental disorders, need effective interventions to prevent them dropping out of school early. Increased detection of psychopathology did not result in decreased dropout rates.
