Psychiatric problems and quality of life in a clinical sample of adolescents: The role of peer relations

Background: The quality of peer relations is linked to mental health in childhood and adolescence, but few studies have investigated its clinical relevance. In particular, the potential mediating role of peer functioning in the associations between different dimensions of symptoms and quality of life (QoL) has not been sufficiently examined. Objective: In a clinical sample of adolescents, we examined peer relations in light of psychiatric diagnoses, as well as QoL and symptoms of mental health problems, with particular focus on symptoms of anxiety, depression, and ADHD. We also examined the potential mediating role of peer problems in the relationship between such symptoms and QoL. Methods: The sample consisted of 603 adolescents (ages 13-18) referred to clinical assessment. Psychiatric diagnoses according to the criteria of the International Statistical Classification of Diseases and Related Health Problems, 10th revision, were collected from participants’ clinical charts. Symptoms of disorders, QoL, and quality of peer relations were measured by self-report questionnaires. Results: Adolescents diagnosed with anxiety/depressive disorder reported more peer problems and lower QoL than adolescents with attention deficit/hyperactivity disorder. These findings were supported with symptom ratings. A path model with bootstrapping was used to assess the potential mediating role of peer problems in the association between symptoms and QoL, showing that peer problems partly mediated the relationship between emotional symptoms and QoL, but not the relationship between ADHD-symptoms and QoL. Conclusion: Improvement of peer relations may be a fruitful path for enhancing QoL among adolescents with symptoms of anxiety and depression

Record linkage of population-based cohort data from minors with national register data : A scoping review and comparative legal analysis of four European countries

Funding Information: We would like to acknowledge Evert-Ben van Veen from the MLC Foundation, Dagelijkse Groenmarkt 2, 2513 AL Den Haag, the Netherlands. The results on the country-specific text on the Netherlands was based on his contribution. Publisher Copyright: © 2021 Doetsch JN et al.Background: The GDPR was implemented to build an overarching framework for personal data protection across the EU/EEA. Linkage of data directly collected from cohort participants, potentially serving as a prominent tool for health research, must respect data protection rules and privacy rights. Our objective was to investigate law possibilities of linking cohort data of minors with routinely collected education and health data comparing EU/EEA member states. Methods: A legal comparative analysis and scoping review was conducted of openly accessible published laws and regulations in EUR-Lex and national law databases on GDPR's implementation in Portugal, Finland, Norway, and the Netherlands and its connected national regulations purposing record linkage for health research that have been implemented up until April 30, 2021. Results: The GDPR does not ensure total uniformity in data protection legislation across member states offering flexibility for national legislation. Exceptions to process personal data, e.g., public interest and scientific research, must be laid down in EU/EEA or national law. Differences in national interpretation caused obstacles in cross-national research and record linkage: Portugal requires written consent and ethical approval; Finland allows linkage mostly without consent through the national Social and Health Data Permit Authority; Norway when based on regional ethics committee's approval and adequate information technology safeguarding confidentiality; the Netherlands mainly bases linkage on the opt-out system and Data Protection Impact Assessment. Conclusions: Though the GDPR is the most important legal framework, national legislation execution matters most when linking cohort data with routinely collected health and education data. As national interpretation varies, legal intervention balancing individual right to informational self-determination and public good is gravely needed for health research. More harmonization across EU/EEA could be helpful but should not be detrimental in those member states which already opened a leeway for registries and research for the public good without explicit consent.Peer reviewe

Common core assessments in follow-up studies of adults born preterm-Recommendation of the Adults Born Preterm International Collaboration

Of all newborns, 1%-2% are born very preterm (VP; <32 weeks) or with very low birthweight (VLBW; ≤1500 g). Advances in prenatal and neonatal care have substantially improved their survival, and the first generations who have benefited from these advances are now entering middle age. While most lead healthy lives, on average these adults are characterised by a number of adversities. These include cardiometabolic risk factors, airway obstruction, less physical activity, poorer visual function, lower cognitive performance, and a behavioural phenotype that includes inattention and internalising and socially withdrawn behaviour that may affect life chances and quality of life. Outcomes in later adulthood are largely unknown, and identifying trajectories of risk or resilience is essential in developing targeted interventions. Joint analyses of data and maintenance of follow-up of cohorts entering adulthood are essential. Such analyses are ongoing within the Adults Born Preterm International Collaboration (APIC; www.apic-preterm.org). Joint analyses require data harmonisation, highlighting the importance of consistent assessment methodologies. To present an expert recommendation on Common Core Assessments to be used in follow-up assessments of adults born preterm. Principles of Common Core Assessments were discussed at APIC meetings. Experts for each specific outcome domain wrote the first draft on assessments pertaining to that outcome. These drafts were combined and reviewed by all authors. Consensus was reached by discussion at APIC meetings. We present a recommendation by APIC experts on consistent measures to be used in adult follow-up assessments. The recommendation encompasses both "core" measures which we recommend to use in all assessments of adults born preterm that include the particular outcome. This will allow comparability between time and location. The recommendation also lists optional measures, focusing on current gaps in knowledge. It includes sections on study design, cardiometabolic and related biomarkers, biological samples, life style, respiratory, ophthalmic, cognitive, mental health, personality, quality of life, sociodemographics, social relationships, and reproduction.

Self-Reported Mental Health Problems Among Adults Born Preterm : A Meta-analysis

CONTEXT: Preterm birth increases the risk for mental disorders in adulthood, yet findings on abstract self-reported or subclinical mental health problems are mixed. OBJECTIVE: To study self-reported mental health problems among adults born preterm at very low birth weight (VLBW; DATA SOURCES: Adults Born Preterm International Collaboration. STUDY SELECTION: Studies that compared self-reported mental health problems using the Achenbach Young Adult Self Report or Adult Self Report between adults born preterm at VLBW (n = 747) and at term (n = 1512). DATA EXTRACTION: We obtained individual participant data from 6 study cohorts and compared preterm and control groups by mixed random coefficient linear and Tobit regression. RESULTS: Adults born preterm reported more internalizing (pooled beta =.06; 95% confidence interval.01 to.11) and avoidant personality problems (.11;.05 to.17), and less externalizing (-.10;-. 15 to-. 06), rule breaking (-.10;-. 15 to-. 05), intrusive behavior (-.14;-. 19 to-.09), and antisocial personality problems (-.09;-. 14 to-.04) than controls. Group differences did not systematically vary by sex, intrauterine growth pattern, neurosensory impairments, or study cohort. LIMITATIONS: Exclusively self-reported data are not confirmed by alternative data sources. CONCLUSIONS: Self-reports of adults born preterm at VLBW reveal a heightened risk for internalizing problems and socially avoidant personality traits together with a lowered risk for externalizing problem types. Our findings support the view that preterm birth constitutes an early vulnerability factor with long-term consequences on the individual into adulthood.Peer reviewe

Mental health, pain and tiredness in adults born very preterm or with very low birthweight

Aim: Adults born preterm have increased risk of mental health problems and other neurodevelopmental conditions. We aimed to investigate associations of mental health with pain and tiredness in adults born very preterm (VP; <32 weeks) or very low birthweight (VLBW; <1500 g) and at term, and whether these associations are influenced by physical activity. Methods: As part of an EU Horizon 2020 project, individual participant data from six prospective cohort studies were harmonised for 617 VP/VLBW and 1122 term‐born participants. Mental health was assessed by the Achenbach System of Empirically Based Assessment Adult Self‐Report. Pain and tiredness were harmonised based on specific items from self‐reported questionnaires. Associations between mental health and pain or tiredness were explored by linear regression. Results: An increase in the mental health scales internalising, externalising and total problems was associated with increased pain and tiredness in the preterm and term group alike. Results were maintained when adjusting for physical activity. Conclusion: The findings indicate that associations between mental health, pain and tiredness in adults are independent of gestation or birthweight. Future research should explore other potential mechanisms that may underlie the increased risk of mental health problems in the preterm population

Neurocognitive function and associations with mental health in adults born preterm with very low birthweight or small for gestational age at term

ObjectivesTo assess neurocognitive function in adults born with low birthweight compared with controls and to explore associations between neurocognitive function and psychopathology in these groups.MethodsIn this prospective cohort study, one group born preterm with very low birthweight (VLBW: birthweight &lt;1,500 g, n = 53), one group born small for gestational age at term (SGA: birthweight &lt;10th percentile, n = 63) and one term-born control group (birthweight ≥10th percentile, n = 81) were assessed with neurocognitive tests, diagnostic interviews, and self-report questionnaires at 26 years of age.ResultsThe VLBW group scored significantly below the control group on several neurocognitive measures, including IQ measures, psychomotor speed, verbal fluency, aspects of visual learning and memory, attention, social cognition, working memory and fine motor speed. The SGA group consistently scored at an intermediate level between the VLBW and the control group and had significantly lower scores than controls on Performance IQ and psychomotor speed, including switching. In the VLBW group, associations were found between lower spatial working memory and the presence of anxiety disorders, internalizing and attention problems, and autistic traits. Furthermore, lower Full scale IQ was associated with attention problems when adjusting for sex and parental socioeconomic status.ConclusionAdults born preterm with VLBW or born term SGA displayed neurocognitive difficulties. Spatial working memory was associated with difficulties with attention, anxiety, and social function of VLBW adults. The finding and its clinical applicability should be further explored

Health-related quality-of-life outcomes of very preterm or very low birth weight adults : evidence from an individual participant data meta-analysis

Background and Objective Assessment of health-related quality of life for individuals born very preterm and/or low birthweight (VP/VLBW) offers valuable complementary information alongside biomedical assessments. However, the impact of VP/VLBW status on health-related quality of life in adulthood is inconclusive. The objective of this study was to examine associations between VP/VLBW status and preference-based health-related quality-of-life outcomes in early adulthood. Methods Individual participant data were obtained from five prospective cohorts of individuals born VP/VLBW and controls contributing to the ‘Research on European Children and Adults Born Preterm’ Consortium. The combined dataset included over 2100 adult VP/VLBW survivors with an age range of 18–29 years. The main exposure was defined as birth before 32 weeks’ gestation (VP) and/or birth weight below 1500 g (VLBW). Outcome measures included multi-attribute utility scores generated by the Health Utilities Index Mark 3 and the Short Form 6D. Data were analysed using generalised linear mixed models in a one-step approach using fixed-effects and random-effects models. Results VP/VLBW status was associated with a significant difference in the Health Utilities Index Mark 3 multi-attribute utility score of − 0.06 (95% confidence interval − 0.08, − 0.04) in comparison to birth at term or at normal birthweight; this was not replicated for the Short Form 6D. Impacted functional domains included vision, ambulation, dexterity and cognition. VP/VLBW status was not associated with poorer emotional or social functioning, or increased pain. Conclusions VP/VLBW status is associated with lower overall health-related quality of life in early adulthood, particularly in terms of physical and cognitive functioning. Further studies that estimate the effects of VP/VLBW status on health-related quality-of-life outcomes in mid and late adulthood are needed

Association studies of up to 1.2 million individuals yield new insights into the genetic etiology of tobacco and alcohol use

Tobacco and alcohol use are leading causes of mortality that influence risk for many complex diseases and disorders 1 . They are heritable 2,3 and etiologically related 4,5 behaviors that have been resistant to gene discovery efforts 6–11 . In sample sizes up to 1.2 million individuals, we discovered 566 genetic variants in 406 loci associated with multiple stages of tobacco use (initiation, cessation, and heaviness) as well as alcohol use, with 150 loci evidencing pleiotropic association. Smoking phenotypes were positively genetically correlated with many health conditions, whereas alcohol use was negatively correlated with these conditions, such that increased genetic risk for alcohol use is associated with lower disease risk. We report evidence for the involvement of many systems in tobacco and alcohol use, including genes involved in nicotinic, dopaminergic, and glutamatergic neurotransmission. The results provide a solid starting point to evaluate the effects of these loci in model organisms and more precise substance use measures
