Eating patterns in a population-based sample of children aged 5 to 7 years: association with psychopathology and parentally perceived impairment.

Objective: There is still a lack of research on childhood eating patterns and their correlates in relation to psychopathology and parentally perceived impact in general population samples. We aimed to determine which eating patterns were more likely to be identified as problematic by parents, and their impact and association with childhood psychopathology (emotional, behavioral, and pervasive developmental disorders) in a general population child cohort. Methods: We collected data as part of the 5- to 7-year-old follow-up of a randomly derived subsample of the Copenhagen Child Cohort 2000. Of the eligible 2912, 1327 (45.6%) children and parents participated in the study. Parents were interviewed using a composite instrument assessing eating behaviors and their impact. Associations with contemporaneous psychopathology were determined using logistic regression. Results: Five eating patterns were identified (good eating/overeating, picky eating, slow/poor eating, delayed eating behaviors, and snacking behaviors); among these, picky eating and slow/poor eating were described as a problem by more than half of parents and they also had high impact. Picky eating was associated with psychopathology across disorders. Emotional undereating was associated with emotional and functional somatic symptoms. A quarter of parents described at least one eating behavior as a problem. Conclusions: Eating behaviors in a general population cohort were differentially associated with impact and psychopathology. Picky eating was highlighted among other behaviors as having negative correlates. Better knowledge of how childhood eating behaviors impact on children and their association with psychopathology will aid adequate assessment and treatment.

Psychotic experiences co-occur with sleep problems, negative affect and mental disorders in preadolescence.

BACKGROUND Knowledge on the significance of childhood psychotic symptoms and experiences (PE) is still limited. This study aimed to investigate the prevalence and clinical significance of PE in preadolescent children from the general population by use of in-depth psychopathological interviews and comprehensive diagnostic assessments. METHODS We investigated 1,632 children from the general population-based Copenhagen Child Cohort 2000. PE were measured by semistructured interviews using the K-SADS-PL-items on psychotic and affective symptoms, each symptom scored as not present versus likely or definitely present. The Development and Well-Being Assessment (DAWBA) was used independently to diagnose DSM-IV-mental disorders. Puberty development and sleep disturbance were self-reported. The associations between PE (any lifetime hallucination and/or delusion) and various mental problems and disorders were examined by multivariable binomial regression analyses, adjusting for gender and onset of puberty. RESULTS The weighted life time prevalence of PE at age 11-12 years was 10.9% (CI 9.1-12.7). The majority of children with PE (n = 172) either had a diagnosable DSM-IV-mental disorder (31.4%) or self-reported mental health difficulties in absence of a diagnosis (31.4%). The risk of delusions increased with onset of puberty. The risk of PE increased with emotional and neurodevelopmental disorders, subthreshold depressive symptoms, sleep problems and lack of sleep, regardless of whether PE were expressed as hallucinations and/or delusions. The highest correlations were seen for emotional and multiple disorders. CONCLUSIONS Psychotic experiences are particularly prevalent in the context of affective dysregulation and sleep disturbance, increase with onset of puberty and represent a trans-diagnostic marker of psychopathology.

Infant behaviors are predictive of functional somatic symptoms at ages 5-7 years: results from the Copenhagen Child Cohort CCC2000.

OBJECTIVE To investigate infancy predictors of impairing functional somatic symptoms (FSS) at child ages 5-7 years with a focus on problems with feeding, sleep, and tactile reactivity. STUDY DESIGN This study is part of a longitudinal birth cohort study, Copenhagen Child Cohort CCC2000. Child health, development, and functioning were assessed by community health nurses at 4 home visits from birth to age 10 months. FSS at ages 5-7 years were measured by the Soma Assessment Interview in 1327 children. Sociodemographic data and information on maternal psychiatric illness were obtained from the Danish National Registers. RESULTS Multiple logistic regression analysis controlled for maternal psychiatric illness and annual household income revealed that combined infancy regulatory problems (ie, at least 2 of 3 problems of feeding, sleeping, or tactile reactivity during the first 10 months of living) predicted impairing FSS at 5-7 years (aOR = 2.9, 95% CI: 1.3-6.6). Maternal psychiatric illness during the childs first year of living was also associated with later child FSS (aOR = 7.1, 95% CI: 1.8-27.8). CONCLUSION Regulatory problems may be an early marker of disturbed sensory reactivity in young children, which together with maternal psychiatric problems, point to possible early risk mechanisms of impairing FSS in childhood.

The CCC2000 Birth Cohort Study of Register-Based Family History of Mental Disorders and Psychotic Experiences in Offspring

Psychotic experiences (PE) in individuals of the general population are hypothesized to mark the early expression of the pathology underlying psychosis. This notion of PE as an intermediate phenotype is based on the premise that PE share genetic liability with psychosis. We examined whether PE in childhood was predicted by a family history of mental disorder with psychosis rather than a family history of nonpsychotic mental disorder and whether this association differed by severity of PE. The study examined data on 1632 children from a general population birth cohort assessed at age 11-12 years by use of a semistructured interview covering 22 psychotic symptoms. The Danish national registers were linked to describe the complete family history of hospital-based psychiatric diagnoses. Uni- and multivariable logistic regressions were used to test whether a family history of any mental disorder with psychosis, or of nonpsychotic mental disorder, vs no diagnoses was associated with increased risk of PE in offspring (hierarchical exposure variable). The occurrence of PE in offspring was significantly associated with a history of psychosis among the first-degree relatives (adjusted relative risk [RR] = 3.29, 95% CI: 1.82-5.93). The risk increased for combined hallucinations and delusions (adjusted RR = 5.90, 95% CI: 2.64-13.16). A history of nonpsychotic mental disorders in first-degree relatives did not contribute to the risk of PE in offspring nor did any mental disorder among second-degree relatives. Our findings support the notion of PE as a vulnerability marker of transdiagnostic psychosis. The effect of psychosis in first-degree relatives may operate through shared genetic and environmental factors.

Functional Somatic Symptoms and Consultation Patterns in 5- to 7-Year-Olds

OBJECTIVE: To investigate the frequency of and factors linked to medical consultation for functional somatic symptoms (FSS) among 5- to 7-year-old children. METHODS: We assessed 1327 children from the Copenhagen Child Cohort 2000 for FSS at ages 5 to 7 years. Register data on past health care use in general practice were compared between children with and those without parent-reported medical consultation for FSS at the age of 5 to 7 years: respective consulters (n = 96) and nonconsulters (n = 211) and children without FSS (n = 1019). Degree of parental worries about the child’s symptoms and parent-reported symptom characteristics and associated impacts were compared between consulters and nonconsulters. RESULTS: Among 308 children with FSS, 31.1% were consulters. Being a consulter was significantly associated with multisymptomatic presentation, parental worries about the symptoms, symptom impact, and a higher past health care use in general practice. Multiple logistic regression analysis controlled for gender, comorbid physical disease, and symptom severity revealed that the number of face-to-face contacts in general practice during the child’s first 4 years of life predicted being an consulter for FSS at 5 to 7 years (odds ratio 1.03, 95% confidence interval 1.00–1.06; odds ratio interpreted per unit change in number of contacts). CONCLUSIONS: This study adds to our understanding of health care use for FSS in childhood by highlighting the influence of parents’ early consultation patterns with their child and the influence of parental perceptions of their child’s health and FSS-related impact on pediatric health care use for FSS. Management of health care use in children with FSS should address these aspects.

Diagnostic practice of psychogenic nonepileptic seizures (PNES) in the pediatric setting

No formal guidelines for diagnosing psychogenic nonepileptic seizures (PNES) in children exist, and little is known about the clinical practice of diagnosing PNES in the pediatric setting. We therefore performed a national survey as a first step to document pediatricians’ current diagnostic practice for PNES.

Psychiatric disorders in Danish children aged 5–7 years: A general population study of prevalence and risk factors from the Copenhagen Child Cohort (CCC 2000)

Abstract Background: Knowledge about the presentation of psychopathology in preschool age and associated risk factors is fundamental to preventive intervention before schooling. Aims: To investigate the full spectrum of psychiatric diagnoses in general population children at the period of transition from preschool to school. Methods: A sample of 1585 children from the Copenhagen Child Cohort, CCC2000 aged 5–7 years was assessed using the Development and Well-Being Assessment (DAWBA) with diagnostic classification by experienced clinicians. Perinatal, sociodemographic and socio-economic data was obtained from Danish national registries. Results: The prevalence of any ICD-10 psychiatric disorder was 5.7% (95%CI: 4.4–7.1). Pervasive developmental disorders (PDD) were found in 1.3% (95%CI: 0.8–1.8) and behavioural and hyperkinetic disorders were found in 1.5% (95%CI: 0.9–2.1) and 1.0% (95%CI: 0.4–1.6), respectively. Emotional disorders were found in 2.9% (95%CI: 1.9–40). More boys were diagnosed with PDD, behavioural disorders and tics. No gender differences were found in hyperactivity disorders (HD) and emotional disorders. Co-morbidity was frequent, in particular between HD and PDD, but also between HD and emotional disorder and behavioural disorder. Teenage mothers, single parents and low household income the first two years after the child’s birth were associated with a three-to fourfold increased risk of psychiatric disorder in the child at age 5–7 years. Conclusion: The study results point to two “windows of opportunity” for prevention. In the earliest postnatal years, prevention should target families at socio-economic risk; and in the years before schooling, intervention should focus on children with symptoms of PDD, HD, and behavioural disorders.

Early Predictors of Childhood Restrictive Eating: A Population-Based Study.

Objective: Childhood eating problems, in particular restrictive eating, are common. Knowledge and understanding of risk mechanisms is still scarce. We aimed to investigate prospective early risk factors for restrictive eating across child, maternal, obstetric, and sociodemographic domains in a population-based sample of Danish 5 to 7 year olds. Method: Data on restrictive eating patterns (picky eating, slow/poor eating, and emotional undereating) collected on 1327 children from the Copenhagen Child Cohort 2000 were linked with registered and routinely collected health nurse data (during the first year of life). Prospective risk factors were investigated in univariable and multivariable regression models. Results: Feeding problems in infancy were prospectively associated with childhood picky eating (odds ratio [OR] = 2.02, 95% confidence interval [CI], 1.20–3.40) and emotional undereating (OR = 1.49, 95% CI, 1.05–2.11). A high thriving index in infancy was inversely associated with both picky and slow/poor eating. Having 2 non-Danish-born parents predicted slow/poor eating (OR = 5.29, 95% CI, 1.16–24.09) in multivariable analyses, as did maternal diagnosis of a psychiatric disorder before child age 5 years in univariable analyses (OR = 6.08, 95% CI, 1.70–21.72). Conclusions: Feeding problems and poor growth in the first year of life show high continuity into childhood restrictive eating. Maternal psychopathology is an important and modifiable risk factor. These findings confirm that early signs of poor eating and growth are persistent and might be useful in predicting eating problems in mid-childhood.

Clinical features of functional somatic symptoms in children and referral patterns to child and adolescent mental health services

Functional somatic symptoms (FSS) are common in paediatric patients who are referred to Child and Adolescent Mental Health Service (CAMHS), but little is known about current referral practices. The aim of this study was to systematically investigate clinical features of paediatric inpatients with FSS referred to CAMHS and to describe why paediatricians referred them.

Psychological Interventions for Children with Functional Somatic Symptoms: A Systematic Review and Meta-Analysis

OBJECTIVE To analyze the effectiveness of psychological treatments on symptom load and associated disability in children with functional somatic symptoms, and to explore potential moderators of effects. STUDY DESIGN Cochrane, PubMed, PsycINFO, EMBASE, and CINAHL were searched for randomized controlled trials published in peer-reviewed journals. Randomized controlled trials studying the effect of a psychological treatment on symptom load and disability in children with functional somatic symptoms were selected. Data on symptom load, disability, and school absence directly post-treatment and at follow-up were extracted by 2 assessors. Studies were appraised with the Cochrane risk of bias tool. Standardized mean differences were pooled in a random-effects model. Heterogeneity in effect-sizes was explored by use of meta-regressions. PROSPERO Registration ID: CRD42015029667. RESULTS Out of 4098 identified records, 27 studies were included in this review of which 21 were included in meta-analyses. Psychological treatments reduced symptom load (Hedges g = -0.61), disability (Hedges g = -0.42), and school absence (Hedges g = -0.51) post-treatment in children suffering from various functional somatic symptoms. Effects were maintained at follow-up. Type and duration of symptoms, age, and treatment dose did not explain heterogeneity in effect-sizes between studies. Effect-sizes should be interpreted with caution because of the variety in outcome measures, unexplained heterogeneity in found effects and potential publication bias. CONCLUSIONS Psychological interventions reduce symptom load, disability, and school absence in children with functional somatic symptoms. Future research should clarify which patient and treatment characteristics modify outcomes.
