Self-reported mental health difficulties were of limited use when screening for psychiatric diagnoses in adults born small for gestational age at term.

AIM: Being born small for gestational age (SGA) at term increases the risk of adverse health outcomes. We examined whether self-reported mental health differed between adults born SGA and non-SGA at term and could be used to screen for psychiatric diagnoses. METHODS: We used the Strengths and Difficulties Questionnaire to gather data from 68 participants born SGA and 88 non-SGA controls at a mean age of 26.5 years. Group differences were analysed by linear regression. We calculated the area under the curve and the sensitivity, specificity and predictive values for psychiatric diagnoses. RESULTS: The mean total difficulties score was 1.9 (95% confidence interval 0.4-3.5) points higher for participants born SGA. They also reported more internalising and emotional problems (p < 0.05). The areas under the curve were 0.82 and 0.68 in the SGA and control groups, respectively. Among participants born SGA, the 90th percentile cut-off had a sensitivity of 0.38, a specificity of 0.93 and positive and negative predictive values of 0.75 and 0.71. The 80th percentile cut-off had higher sensitivity and lower specificity. CONCLUSION: Adults born SGA reported more mental health difficulties than non-SGA controls. The low sensitivity using the 90th percentile cut-off suggests that a lower cut-off should be considered.

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.

Atypical brain structure mediates reduced IQ in young adults born preterm with very low birth weight.

Preterm birth with very low birth weight (VLBW) confers heightened risk for perinatal brain injury and long-term cognitive deficits, including a reduction in IQ of up to one standard deviation. Persisting gray and white matter aberrations have been documented well into adolescence and adulthood in preterm born individuals. What has not been documented so far is a plausible causal link between reductions in cortical surface area or subcortical brain structure volumes, and the observed reduction in IQ. The NTNU Low Birth Weight in a Lifetime Perspective study is a prospective longitudinal cohort study, including a preterm born VLBW group (birthweight ≤1500 g) and a term born control group. Structural magnetic resonance imaging data were obtained from 38 participants aged 19, born preterm with VLBW, and 59 term-born peers. The FreeSurfer software suite was used to obtain measures of cortical thickness, cortical surface area, and subcortical brain structure volumes. Cognitive ability was estimated using the Wechsler Adult Intelligence Scale, 3rd Edition, including four IQ-indices: Verbal comprehension, Working memory, Perceptual organization, and Processing speed. Statistical mediation analyses were employed to test for indirect effects of preterm birth with VLBW on IQ, mediated by atypical brain structure. The mediation analyses revealed negative effects of preterm birth with VLBW on IQ that were partially mediated by reduced surface area in multiple regions of frontal, temporal, parietal and insular cortex, and by reductions in several subcortical brain structure volumes. The analyses did not yield sufficient evidence of mediation effects of cortical thickness on IQ. This is, to our knowledge, the first time a plausible causal relationship has been established between regional cortical area reductions, as well as reductions in specific subcortical and cerebellar structures, and general cognitive ability in preterm born survivors with VLBW.

Body composition in adults born preterm with very low birth weight.

BACKGROUND: Studies on body composition in preterm very low birth weight (VLBW < 1500 g) survivors are inconsistent and trajectories later in life unknown. We assessed body composition and its change from young to mid-adulthood in VLBW adults. METHODS: We studied 137 VLBW adults and 158 term-born controls from two birth cohorts in Finland and Norway at mean age 36 years. Body composition was assessed by 8-polar bioelectrical impedance. We compared results with dual-energy x-ray absorptiometry measurements at 24 years. RESULTS: In mid-adulthood, VLBW women and men were shorter than controls. Fat percentage (mean difference in women 1.1%; 95% CI, -1.5% to 3.5%, men 0.8%; -2.0% to 3.6%) and BMI were similar. VLBW women had 2.9 (0.9 to 4.8) kg and VLBW men 5.3 (2.7 to 8.1) kg lower lean body mass than controls, mostly attributable to shorter height. Between young and mid-adulthood, both groups gained fat and lean body mass (p for interaction VLBW x age>0.3). CONCLUSION: Compared with term-born controls, VLBW adults had similar body fat percentage but lower lean body mass, largely explained by their shorter height. This could contribute to lower insulin sensitivity and muscular fitness previously found in VLBW survivors and predispose to functional limitations with increasing age. IMPACT: In mid-adulthood, individuals born preterm with very low birth weight had similar body fat percentage but lower lean body mass than those born at term. This was largely explained by their shorter height. First study to report longitudinal assessments of body size and composition from young to mid-adulthood in very low birth weight adults. Lower lean body mass in very low birth weight adults could contribute to lower insulin sensitivity and muscular fitness and lead to earlier functional limitations with increasing age.

ADHD symptoms and diagnosis in adult preterms: systematic review, IPD meta-analysis, and register-linkage study.

BACKGROUND: This study examined differences in ADHD symptoms and diagnosis between preterm and term-born adults (≥18 years), and tested if ADHD is related to gestational age, birth weight, multiple births, or neonatal complications in preterm borns. METHODS: (1) A systematic review compared ADHD symptom self-reports and diagnosis between preterm and term-born adults published in PubMed, Web of Science, and PROQUEST until April 2021; (2) a one-stage Individual Participant Data(IPD) meta-analysis (n = 1385 preterm, n = 1633 term; born 1978-1995) examined differences in self-reported ADHD symptoms[age 18-36 years]; and (3) a population-based register-linkage study of all live births in Finland (01/01/1987-31/12/1998; n = 37538 preterm, n = 691,616 term) examined ADHD diagnosis risk in adulthood (≥18 years) until 31/12/2016. RESULTS: Systematic review results were conflicting. In the IPD meta-analysis, ADHD symptoms levels were similar across groups (mean z-score difference 0.00;95% confidence interval [95% CI] -0.07, 0.07). Whereas in the register-linkage study, adults born preterm had a higher relative risk (RR) for ADHD diagnosis compared to term controls (RR = 1.26, 95% CI 1.12, 1.41, p < 0.001). Among preterms, as gestation length (RR = 0.93, 95% CI 0.89, 0.97, p < 0.001) and SD birth weight z-score (RR = 0.88, 95% CI 0.80, 0.97, p < 0.001) increased, ADHD risk decreased. CONCLUSIONS: While preterm adults may not report higher levels of ADHD symptoms, their risk of ADHD diagnosis in adulthood is higher. IMPACT: Preterm-born adults do not self-report higher levels of ADHD symptoms, yet are more likely to receive an ADHD diagnosis in adulthood compared to term-borns. Previous evidence has consisted of limited sample sizes of adults and used different methods with inconsistent findings. This study assessed adult self-reported symptoms across 8 harmonized cohorts and contrasted the findings with diagnosed ADHD in a population-based register-linkage study. Preterm-born adults may not self-report increased ADHD symptoms. However, they have a higher risk of ADHD diagnosis, warranting preventive strategies and interventions to reduce the presentation of more severe ADHD symptomatology in adulthood.

Mental health in adults born preterm with very low birth weight at 14 and 26 years of age assessed by the Strengths and Difficulties Questionnaire.

AIM: Very low birth weight (VLBW: <1500 g) is associated with risk of adverse long-term outcomes, including mental health problems. We assessed whether self-reported mental health differed between young adults born preterm with VLBW and term-born controls. We also examined changes in mental health from 14 to 26 years. METHODS: In a prospective cohort study, 61 VLBW and 88 control participants completed the Strengths and Difficulties Questionnaire at 26 years. Group differences were analysed by linear regression with adjustment for sex and parental socioeconomic status. Longitudinal changes from 14 to 26 years were analysed using linear mixed model. RESULTS: Mean total difficulties score was 1.9 (95% CI: 0.5 to 3.5) higher in the VLBW than in the control group. Internalising and its subscale emotional problems as well as externalising and its subscale hyperactivity/inattention symptoms were higher in the VLBW group. From 14 to 26 years, changes in emotional symptoms, peer relationship problems, externalising problems, hyperactivity/inattention, and prosocial behaviour differed between the groups. CONCLUSION: At 26 years, VLBW participants had more self-reported mental health difficulties than controls. Emotional symptoms increased from 14 to 26 years in the VLBW group, whereas hyperactivity and inattention did not decrease with age as it did in the control group.

Multidisciplinary and neuroimaging findings in preterm born very low birthweight individuals from birth to 28 years of age: A systematic review of a Norwegian prospective cohort study.

BACKGROUND: Children born preterm with very low birthweight (VLBW) face long-lasting neurodevelopmental challenges, where multidisciplinary assessments are warranted. The International Classification of Functioning, Disability and Health (ICF) provides a framework for understanding and conceptualising these outcomes. OBJECTIVES: We aimed to review clinical and neuroimaging findings from birth to adulthood in a Norwegian cohort of individuals born preterm with VLBW (gestational age <37 weeks, birthweight ≤1500 g) within the framework of ICF. DATA SOURCES: We searched PubMed and Embase for articles reporting results of the Norwegian University of Science and Technology (NTNU) Low Birth Weight in a Lifetime Perspective study. STUDY SELECTION AND DATA EXTRACTION: We included original articles reporting proportions of adverse outcomes, mean group differences, risk factors or associations between outcomes. Data were extracted according to ICF's two-level classification. Body functions and structures comprised outcomes of brain structures, cognition, mental health, vision, pain and physical health. Activities and participation comprised motor skills, general and social functioning, education, employment, and health-related quality of life. SYNTHESIS: We performed a qualitative synthesis of included articles. Where mean (SD) was reported, we calculated group differences in SD units. RESULTS: Fifty-eight publications were included. Within body functions and structures, increased prevalence of brain structure pathology, lower cognitive performance, mental health problems, visual and physical health impairments through childhood, adolescence and young adulthood were reported among preterm VLBW participants compared with controls. Within activities and participation, motor problems, lower general and social functioning, and lower academic attainment were found. Perinatal factors were associated with several outcomes, and longitudinal findings suggested persistent consequences of being born preterm with VLBW. CONCLUSIONS: Being born preterm with VLBW has long-term influences on body functions and structures, activities and participation. The ICF is appropriate for assessing general domains of functioning and guiding the management of individuals born preterm with VLBW.

Outcomes and predictors of functioning, mental health, and health-related quality of life in adults born with very low birth weight: a prospective longitudinal cohort study.

BACKGROUND: Very low birth weight (VLBW: ≤1500 g) is associated with multiple short and long-term complications. This study aimed to examine outcomes and predictors of functioning, mental health, and health-related quality of life in adults born with VLBW. METHODS: In this prospective longitudinal cohort study, 67 VLBW and 102 control participants were assessed using the Adult Self-Report of the Achenbach System of Empirically Based Assessment and Global Assessment of Functioning at 26 years, and the Hospital Anxiety and Depression Scale and Short Form-36 at 28 years of age. Associations between perinatal and childhood predictors and adult functioning were assessed using linear regression. RESULTS: Compared with controls, the VLBW group had lower mean raw scores on the Function and Symptom subscales of the Global Assessment of Functioning at 26 years, a higher sum score of symptoms of anxiety and depression due to more depressive symptoms, and poorer mental health-related quality of life at 28 years. The mean group differences ranged from 0.42 to 0.99 SD. Within the VLBW group, lower birth weight and gestational age, a higher number of days with respiratory support and poorer motor function at 14 years were associated with a higher sum score of symptoms of anxiety and depression at 28 years. Days with respiratory support and motor function at 14 years were also predictive of Global Assessment of Functioning scores at 26 years, and mental health-related quality of life at 28 years. Poorer motor and cognitive function at five years were associated with poorer physical health-related quality of life at 28 years. Parental socioeconomic status was related to mental and physical health-related quality of life. CONCLUSION: In this study, VLBW adults reported poorer functioning and mental health-related quality of life, and more depressive symptoms than their term born peers. Days with respiratory support and adolescent motor function predicted most of the adult outcomes. This study explicates perinatal and developmental markers during childhood and adolescence which can be target points for interventions.

Common Core Assessments in follow-up studies of adults born preterm-Recommendation of the Adults Born Preterm International Collaboration.

BACKGROUND: 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. OBJECTIVE: To present an expert recommendation on Common Core Assessments to be used in follow-up assessments of adults born preterm. METHODS: 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. RESULTS: We present a recommendation by APIC experts on consistent measures to be used in adult follow-up assessments. CONCLUSIONS: 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.

Reduced white matter fractional anisotropy mediates cortical thickening in adults born preterm with very low birthweight.

Development of the cerebral cortex may be affected by aberrant white matter development. Preterm birth with very low birth weight (VLBW) has been associated with reduced fractional anisotropy of white matter and changes in cortical thickness and surface area. We use a new methodological approach to combine white and gray matter data and test the hypothesis that white matter injury is primary, and acts as a mediating factor for concomitant gray matter aberrations, in the developing VLBW brain. T1 and dMRI data were obtained from 47 young adults born preterm with VLBW and 73 term-born peers (mean age = 26). Cortical thickness was measured across the cortical mantle and compared between the groups, using the FreeSurfer software suite. White matter pathways were reconstructed with the TRACULA software and projected to their cortical end regions, where cortical thickness was averaged. In the VLBW group, cortical thickness was increased in anteromedial frontal, orbitofrontal, and occipital regions, and fractional anisotropy (FA) was reduced in frontal lobe pathways, indicating compromised white matter integrity. Statistical mediation analyses demonstrated that increased cortical thickness in the frontal regions was mediated by reduced FA in the corpus callosum forceps minor, consistent with the notion that white matter injury can disrupt frontal lobe cortical development. Combining statistical mediation analysis with pathway projection onto the cortical surface offers a powerful novel tool to investigate how cortical regions are differentially affected by white matter injury.

Psychiatric symptoms and risk factors in adults born preterm with very low birthweight or born small for gestational age at term.

BACKGROUND: We aimed to examine psychiatric symptoms in adults born preterm with very low birthweight or born at term small for gestational age compared with normal birthweight peers, and examine associations with perinatal factors and childhood motor and cognitive function. METHODS: In this longitudinal cohort study, one preterm born group with very low birthweight (VLBW: birthweight ≤1500 g), one term-born Small for Gestational Age (SGA: birthweight <10th percentile) group and one term-born non-SGA control group, were assessed at 26 years of age. Primary outcomes were scores on self-reported questionnaires: Achenbach System of Empirically Based Assessment - Adult Self-Report, The Autism-Spectrum Quotient and Peters et al. Delusions Inventory. Exposure variables were perinatal data, while childhood motor and cognitive function were examined as possible early markers. RESULTS: Both the preterm VLBW and the term SGA group reported higher levels of attention, internalizing and externalizing problems compared to the control group. In addition, the VLBW participants reported more critical items and a higher proportion had intermediate level autistic traits, while the SGA participants reported more intrusive behavior. Increasing length of respiratory support and hospital stay in the neonatal period, and motor problems in early adolescence, were associated with adult psychiatric symptoms in the VLBW group. CONCLUSIONS: Psychiatric symptoms were frequent in the preterm VLBW group and also in the term-born SGA group. Those who were sickest as babies were most at risk. Motor problems can possibly serve as an early marker of adult psychiatric symptoms in low birthweight individuals.

Developmental course of anxiety and depression from adolescence to young adulthood in a prospective Norwegian clinical cohort.

Anxiety and depression are often co-occurring disorders, reflecting both homotypic and heterotypic continuity as possible developmental pathways. The present study aimed to examine homotypic and heterotypic continuities of anxiety and depression across 3 years in adolescence and young adulthood. Participants included patients presenting to psychiatric care with diagnoses of anxiety and/or depressive disorders aged 13-18 at T1 (N = 717, 44% initial participation rate) and aged 16-21 at T2 (N = 549, 80% follow-up participation rate). McNemar's mid-p test and ordinal proportional odds logistic regression analyses were used to assess changes in prevalence within and across diagnostic categories, respectively. More adolescents had an anxiety disorder (+ 11%), whereas fewer had a depressive disorder (- 11%), at T2 compared to T1. Of adolescents with anxiety and/or depression at T1, only 25% recovered or were non-symptomatic 3 years after referral to a psychiatric clinic. Homotypic continuity was observed for anxiety disorders in general (OR = 2.33), for phobic anxiety disorders (OR = 7.45), and for depressive disorders (OR = 2.15). For heterotypic continuity, depression predicted later anxiety (OR = 1.92), more specifically social anxiety (OR = 2.14) and phobic anxiety disorders (OR = 1.83). In addition, social anxiety predicted later generalized anxiety disorder (OR = 3.11). Heterotypic continuity was thus more common than homotypic continuity. For adolescents presenting with anxiety or depression, treatment should, therefore, target broad internalizing symptom clusters, rather than individual diagnoses. This may contribute to prevent future mental illness, particularly anxiety, in clinical samples.

A longitudinal study of associations between psychiatric symptoms and disorders and cerebral gray matter volumes in adolescents born very preterm.

BACKGROUND: Being born preterm with very low birthweight (VLBW ≤ 1500 g) poses a risk for cortical and subcortical gray matter (GM) abnormalities, as well as for having more psychiatric problems during childhood and adolescence than term-born individuals. The aim of this study was to investigate the relationship between cortical and subcortical GM volumes and the course of psychiatric disorders during adolescence in VLBW individuals. METHODS: We followed VLBW individuals and term-born controls (birth weight ≥10th percentile) from 15 (VLBW;controls n = 40;56) to 19 (n = 44;60) years of age. Of these, 30;37 individuals were examined longitudinally. Cortical and subcortical GM volumes were extracted from MRPRAGE images obtained with the same 1.5 T MRI scanner at both time points and analyzed at each time point with the longitudinal stream of the FreeSurfer software package 5.3.0. All participants underwent clinical interviews and were assessed for psychiatric symptoms and diagnosis (Schedule for Affective Disorders and Schizophrenia for School-age Children, Children's Global Assessment Scale, Attention-Deficit/Hyperactivity Disorder Rating Scale-IV). VLBW adolescents were divided into two groups according to diagnostic status from 15 to 19 years of age: persisting/developing psychiatric diagnosis or healthy/becoming healthy. RESULTS: Reduction in subcortical GM volume at 15 and 19 years, not including the thalamus, was limited to VLBW adolescents with persisting/developing diagnosis during adolescence, whereas VLBW adolescents in the healthy/becoming healthy group had similar subcortical GM volumes to controls. Moreover, across the entire VLBW group, poorer psychosocial functioning was predicted by smaller subcortical GM volumes at both time points and with reduced GM volume in the thalamus and the parietal and occipital cortex at 15 years. Inattention problems were predicted by smaller GM volumes in the parietal and occipital cortex. CONCLUSIONS: GM volume reductions in the parietal and occipital cortex as well as smaller thalamic and subcortical GM volumes were associated with the higher rates of psychiatric symptoms found across the entire VLBW group. Significantly smaller subcortical GM volumes in VLBW individuals compared with term-born peers might pose a risk for developing and maintaining psychiatric diagnoses during adolescence. Future research should explore the possible role of reduced cortical and subcortical GM volumes in the pathogenesis of psychiatric illness in VLBW adolescents.

Resilience factors may moderate the associations between pubertal timing, body mass and emotional symptoms in adolescence.

AIM: The effects of resilience factors on associations between emotional symptoms and perceived pubertal timing or body mass in adolescence are unknown, and this study examined the moderating effects of social competence, family cohesion and loneliness. METHODS: Data were drawn from the Young-HUNT 3 study, including a self-report questionnaire and clinical measurements of weight and height from 7639 adolescents aged 13-18 years. Emotional symptoms were assessed by a five-item version of the Hopkins Symptom Checklist. Associations between pubertal timing or body mass and emotional symptoms were assessed by linear regression models. Interactions with social competence, family cohesion and loneliness were explored. RESULTS: A U-shaped relationship was found for both perceived pubertal timing and for perceived body mass and emotional symptoms. For girls, early perceived pubertal timing was more strongly associated with emotional symptoms among those who often felt lonely. For boys, late perceived pubertal timing and feeling they were fat were more strongly associated with emotional symptoms in those with low scores for social competence or family cohesion. CONCLUSION: Emotional symptoms were more strongly associated with perceived pubertal timing and body mass than actual measures and the associations were stronger for adolescents with low scores for resilience factors.

Improved quality of life among adolescents with attention-deficit/hyperactivity disorder is mediated by protective factors: a cross sectional survey.

BACKGROUND: The aim of this study was to assess the role of protective factors as mediators and/or moderators of the relationship between coexisting emotional and conduct problems and quality of life (QoL) among adolescents with attention-deficit/hyperactivity disorder (ADHD). METHODS: The sample consisted of 194 adolescents with ADHD. Participants completed measures of individual competencies, family cohesion and social support, and QoL. Coexisting emotional and conduct problems were assessed using the Strength and Difficulties Questionnaire. RESULTS: Individual competencies and social support mediated the association between emotional and conduct problems and QoL. Family cohesion was associated with both emotional and conduct problems. No moderating effects of protective factors and coexisting problems were found. CONCLUSIONS: The assessment of individual competencies, social resources, and family cohesion may identify potential treatment goals for adolescents with ADHD and coexisting problems, and may contribute to improvements in QoL.

Associations between parental chronic pain and self-esteem, social competence, and family cohesion in adolescent girls and boys--family linkage data from the HUNT study.

BACKGROUND: Parental chronic pain has been associated with adverse outcomes in offspring. However, knowledge on individual and family resilience factors in adolescent offspring of chronic pain sufferers is scarce. This study thus aimed to investigate the associations between parental chronic pain and self-esteem, social competence, and family cohesion levels reported by adolescent girls and boys. METHODS: Based on cross-sectional surveys from the Nord Trøndelag Health Study (the HUNT 3 study), the study used independent self-reports from adolescents aged 13 to 18 years (n = 3227) and their parents and conducted separate linear regression analyses for girls and boys. RESULTS: Concurrent maternal and paternal chronic pain was associated with reduced self-esteem, social competence, and family cohesion in girls. Moreover, maternal chronic pain was associated with higher social competence in boys and reduced self-esteem in girls. The majority of the observed associations were significantly different between girls and boys. Paternal chronic pain was not found to be associated with child outcomes. CONCLUSIONS: The findings indicate that the presence of both maternal and paternal chronic pain could be a potential risk factor for lower levels of individual and family resilience factors reported by girls. Further research on the relationship between parental pain and sex-specific offspring characteristics, including positive resilience factors, is warranted. The study demonstrates the importance of targeting the entire family in chronic pain care.

Chronic multisite pain in adolescent girls and boys with emotional and behavioral problems: the Young-HUNT study.

The aim of this study was to assess the prevalence of chronic multisite pain with high disability in relation to emotional or behavioral problems and resilience factors in adolescence. A second aim was to investigate if resilience factors could attenuate the associations between psychiatric symptoms and chronic multisite pain. The study was based on a large cross-sectional study carried out in Norway between 2006 and 2008 and included 7,070 adolescents aged 13-19 years. Chronic multisite pain was defined as pain at least once a week during the last 3 months, scoring high on a disability index, and occurring in three or more locations. Chronic multisite pain was prevalent among adolescents with high scores (>85%) for anxiety/depression, social anxiety, conduct or attention problems (22.8-31.0 for girls, 8.8-19.0% for boys). Several coexistent psychiatric symptoms increased the prevalence of chronic multisite pain for both girls and boys. Resilience factors, including high self-esteem, seldom feeling lonely, and high scores for family cohesion or social competence, were associated with a lower prevalence and markedly attenuated the association between psychiatric symptoms and chronic multisite pain. Psychiatrists should be careful to assess and treat comorbid chronic pain in adolescents with emotional or behavioral problems.

Self-reported social anxiety symptoms and correlates in a clinical (CAP) and a community (Young-HUNT) adolescent sample.

PURPOSE: The frequencies of social anxiety symptoms in a mental health clinical and a community sample of adolescents are compared. Also, we explore if adolescents can be classified in subgroups based on social anxiety symptoms. Associations between social anxiety symptoms and coexisting problems and sociodemographic characteristics are examined. METHODS: Adolescent participants, aged 13-18, in two large Norwegian studies, consisting of a clinical (n = 694, 42.1% participation rate, 55% girls, mean age = 15.6) and a community (n = 7,694, 73.1% participation rate, 51% girls, mean age = 15.8) sample completed identical self-report questionnaires measuring social anxiety and related variables. RESULTS: Median sum scores (interquartile range) of social anxiety symptoms were higher among girls than boys and in the clinical [girls = 16 (12-22); boys = 12 (9-16)] compared to the community sample [girls = 12 (9-15); boys = 10 (7-12)] (p < 0.001). Latent profile analysis revealed two classes of adolescents based on social anxiety profiles. Adolescents scoring high on social anxiety symptoms, which ranged from 16% (boys in community sample) to 40% (girls in clinical sample), had significantly more coexisting problems than those scoring low. Social anxiety symptoms were associated with academic school problems, bullying, eating problems, acne, and general anxiety and depression in both samples. CONCLUSION: Social anxiety symptoms were commonly reported by adolescents, in both clinical and community settings. These symptoms were associated with a broad spectrum of coexisting problems, which can be used to detect adolescents struggling with social anxiety. Adolescent, family, peer, school, and community interventions targeting these associated problems may contribute to prevent and alleviate social anxiety symptoms.

Visual outcomes and their association with grey and white matter microstructure in adults born preterm with very low birth weight.

Individuals born with very low birth weight (VLBW; < 1500 g) have a higher risk of reduced visual function and brain alterations. In a longitudinal cohort study, we assessed differences in visual outcomes and diffusion metrics from diffusion tensor imaging (DTI) at 3 tesla in the visual white matter pathway and primary visual cortex at age 26 in VLBW adults versus controls and explored whether DTI metrics at 26 years was associated with visual outcomes at 32 years. Thirty-three VLBW adults and 50 term-born controls was included in the study. Visual outcomes included best corrected visual acuity, contrast sensitivity, P100 latency, and retinal nerve fibre layer thickness. Mean diffusivity, axial diffusivity, radial diffusivity, and fractional anisotropy was extracted from seven regions of interest in the visual pathway: splenium, genu, and body of corpus callosum, optic radiations, lateral geniculate nucleus, inferior-fronto occipital fasciculus, and primary visual cortex. On average the VLBW group had lower contrast sensitivity, a thicker retinal nerve fibre layer and higher axial diffusivity and radial diffusivity in genu of corpus callosum and higher radial diffusivity in optic radiations than the control group. Higher fractional anisotropy in corpus callosum areas were associated with better visual function in the VLBW group but not the control group.

Physical activity and cognitive function in adults born very preterm or with very low birth weight-an individual participant data meta-analysis.

OBJECTIVE: Individuals born very preterm (<32 weeks of gestation) or with very low birthweight (<1500g) have lower cognitive function compared with term-born peers. Furthermore, some studies suggest that they are less physically active as young adults than controls, but the relationship between physical activity and cognitive function remains unclear. We performed an individual participant data meta-analysis to examine whether being born preterm/with very low birth weight is associated with physical activity in adulthood and examined if cognitive function mediates this association. STUDY DESIGN: Cohorts with data on physical activity and cognitive function in adults born very preterm/very low birth weight and term-born controls were recruited from the Research on European Children and Adults Born Preterm, and the Adults Born Preterm International Collaboration Consortia. A systematic literature search was performed in PubMed and Embase. RESULTS: Five cohorts with 1644 participants aged 22-28 years (595 very preterm/very low birth weight and 1049 controls) were included. Adults born very preterm/very low birth weight reported 1.11 (95% CI: 0.68 to 1.54) hours less moderate to vigorous physical activity per week than controls, adjusted for cohort, age and sex. The difference between individuals born very preterm/very low birth weight and controls was larger among women than among men. Neither intelligence quotient nor self-reported executive function mediated the association between very preterm/very low birth weight and moderate to vigorous physical activity. Results were essentially the same when we excluded individuals with neurosensory impairments. CONCLUSION: Adults born very preterm/very low birth weight, especially women, reported less moderate to vigorous physical activity than their term-born peers. Cognitive function did not mediate this association. Considering the risk of adverse health outcomes among individuals born preterm, physical activity could be a target for intervention.
