Children's health-related quality of life, neighbourhood socio-economic deprivation and social capital. A contextual analysis

Neighbourhood objective socio-economic indicators and community-reported subjective measures of social capital were examined in relation to childrens health-related quality of life in the Netherlands. Three different data-sources were used: (1) objective neighbourhood socio-economic indicators, (2) subjective neighbourhood data on social capital, and (3) individual data of a family cohort study, including questions on childrens health-related quality of life, and family socio-economic status. Multilevel analyses were conducted using both neighbourhood level and individual level data. Neighbourhood socio-economic status and social capital were associated. Measures of socio-economic deprivation and social capital were both non-specifically associated with childrens general health and satisfaction, independent of possible individual-level confounders. However, childrens mental health and behaviour were specifically associated with one aspect of social capital, the degree of informal social control in the neighbourhood.

Neighbourhood level and individual level SES effects on child problem behaviour: a multilevel analysis

OBJECTIVE This study examined whether neighbourhood level socioeconomic variables have an independent effect on reported child behaviour problems over and above the effect of individual level measures of socioeconomic status. DESIGN AND SETTING Multilevel analysis of cross sectional survey data relating individual level child behavioural problems and parental measures of socioeconomic status with neighbourhood level measures of socioeconomic deprivation in the city of Maastricht, the Netherlands. PARTICIPANTS Children born in the years 1990–1991 attending the second grade of normal kindergarten schools in the city of Maastricht, the Netherlands. Out of 1417 eligible 5–7 year olds, the parents of 734 children (51.8%) agreed to participate. MAIN RESULTS Child behaviour problems were more frequent in families of low parental occupation and education (F=14.51, df 3, 721, p<0.001; F=12.20, df 3, 721, p<0.001, respectively) and in families living in deprived neighbourhoods (F=13.26, df 2, 722, p<0.001). Multilevel random effects regression analysis showed that the effect of neighbourhood level deprivation remained after adjustment for individual level socioeconomic status (B over three levels of deprivation: 1.36; 95%CI=0.28, 2.45). CONCLUSIONS Living in a more deprived neighbourhood is associated with higher levels of child problem behaviour, irrespective of individual level socioeconomic status. The additional effect of the neighbourhood may be attributable to contextual variables such as the level of social cohesion among residents.

Prevalence and characteristics of headache in Dutch schoolchildren.

The aim of this study was to determine whether there has been an increase in headache prevalence in Dutch children and to compare headache characteristics of children with low, medium and high headache severity.

Verbal fluency over time as a measure of automatic and controlled processing in children with ADHD

The performance of ADHD children on semantic category fluency (SCF) versus initial letter fluency (ILF) tasks was examined. For each participant, word production was recorded for each 15-s time slice on each task. Performance on both fluency tasks was compared to test the hypothesis that children with ADHD are characterized by a performance deficit on the ILF task because performance on this task is less automated than performance on the SCF. Children classified with ADHD (N = 20) were compared to children with other psychopathology (N = 118) and healthy controls (N = 130). Results indicated that the groups could not be differentiated by the total number of words produced in 60 s in either fluency task. As hypothesized, a significant interaction of group by productivity over time by type of fluency task was found: ADHD children had more problems finding words in the first 15 s of the IFL than did children in the other two groups, and as compared with their performance on the SCF. Results were taken to indicate that children with ADHD symptoms show a delay in the development of automating skills for processing abstract verbal information.

Child Psychiatric Diagnoses in a Population of Dutch Schoolchildren Aged 6 to 8 Years

OBJECTIVE To determine the prevalence rates of child psychiatric diagnoses in a school-based population of children aged 6 to 8 years in the south of the province of Limburg (The Netherlands). METHOD In a two-stage design 1,317 children were screened with the Child Behavior Checklist. From 403 of these children, child psychiatric information was obtained with the Amsterdam Diagnostic Interview for Children and Adolescents (ADIKA, DSM-III-R/IV). Data were generalized to the responder group (n = 1,317) and to the entire cohort (N = 2,290). For the latter procedure, a prediction model was used to generalize ADIKA results to the nonresponders (n = 973). RESULTS Estimates of the prevalence of different ADIKA diagnoses in the responder group were quite comparable with those for the entire cohort. Twenty-four percent of the entire cohort met criteria for a single disorder, and 21.0% met criteria for two or more disorders. However, in only 5.7% of the cases parents did report a need for help. CONCLUSIONS Where other studies generalize psychiatric diagnoses to the responder group only, this report adds new information by generalizing the prevalence to a school-based cohort of children aged 6 to 8 years. These prevalence estimates are of importance with regard to the demand for care for child psychopathology.

Semantic category fluency versus initial letter fluency over 60 seconds as a measure of automatic and controlled processing in healthy school-aged children

Verbal fluency was operationalized as the number of words produced in a restricted category (i.e., semantic category [SCF] and words beginning with a given letter [ILF]) in 60 seconds. Word production in the first 15 seconds of either type of fluency task was defined as a measure of automatic information processing, whereas word production in the remaining 45 seconds (in 15-second periods) was taken as a measure of controlled information processing. Data revealed that over 60 seconds healthy children aged 8.4–9.7 years (n = 91) produced significantly more words and less incorrect responses on the SCF task than on the ILF task. Although word production was a function of both type of task and time, it was highest in the initial time slice of either type of fluency and decreased as time on task increased. Finally, no sex differences were found for any measure of performance on either type of fluency task. In contrast, the level of occupational achievement of the caregiver (LOA) appeared to be a determinant of the child’s performance on either type of fluency task, indicating that LOA affects higher-order processes, such as the automation of newly learned verbal skills and effortful processing.

Neurocognitive performance of 5- and 6-year-old children who met criteria for attention deficit/hyperactivity disorder at 18 months follow-up: results from a prospective population study.

The aim of this prospective study was to examine whether neurocognitive performance of children aged 5–6 years distinguished children who were later diagnosed with attention deficit/hyperactivity disorder (ADHD) or “borderline ADHD” from children without ADHD after adjustment for behavioral measures and to examine the influence of comorbid psychopathology. Out of a general population of 1,317 children, 366 children were selected on the basis of their scores on the Child Behavior Checklist (CBCL). Eighteen months later, the parents were interviewed using a standardized child psychiatric interview: 33 children were classified as ADHD and 75 children as borderline ADHD, and there were 258 children without ADHD. Children with rated ADHD were significantly impaired on measures of visuomotor ability and working memory compared to children without ADHD after adjustment for CBCL results. The performance of borderline ADHD children was in between that of children with and without ADHD. In addition, 4 groups of children were analyzed: 9 ADHD, 24 ADHD with comorbid oppositional defiant disorder/conduct disorder (ODD/CD), 59 ODD/CD, and 274 controls. Children with rated comorbid ADHD and ODD/CD performed significantly worse on these tasks compared to children with rated ODD/CD and control children while they did not differ from ADHD children. Our results imply that neurocognitive measures can contribute to the early identification of ADHD with and without comorbid ODD/CD.

Children's mental health service use, neighbourhood socioeconomic deprivation, and social capital.

Abstract.Background:There is accumulating evidence that the shared social environment at the neighbourhood level exerts significant effects on health over and above individual level variables. The aim of this study was to assess the interactive influence of neighbourhood measures of socioeconomic deprivation and social capital (i. e. informal social control, social cohesion and trust) on children’s mental health service use, independent of individual level confounders.Methods:Two different data sources were used: 1) individual socioeconomic measures, derived from a case-control study in which case/control status indicated mental health service use or not, and 2) neighbourhood measures of socioeconomic deprivation and social capital. The data were subjected to multilevel logistic regression analysis.Results:Children living in more deprived neighbourhoods run a higher risk of coming into contact with mental health care services. The social capital variables (informal social control and social cohesion and trust) did not exert main effects, but strong trust and social cohesion between citizens in the neighbourhood mitigated the risk-increasing effect of socioeconomic deprivation on children’s mental health service use.Conclusions:The deleterious effects of socioeconomic deprivation on mental health service use in children are sensitive to the context of cohesion and trust in neighbourhoods. Effects of deprivation on children’s mental health cannot be interpreted without taking into account the context of social capital.

A Longitudinal Community Study: Do Psychosocial Risk Factors and Child Behavior Checklist Scores at 5 Years of Age Predict Psychiatric Diagnoses at a Later Age?

OBJECTIVE To examine the extent to which certain risk factors in 5- to 6-year-old children predict later psychopathology in a population-based sample of children from the province of Limburg in the south of the Netherlands. METHOD Of the 2,290 children of interest, 1,317 children were screened with the Child Behavior Checklist (CBCL) and psychosocial risk factors for these children were collected. On the basis of the CBCL ratings, 403 children participated in the second stage in which, 1.5 years later, standardized child psychiatric information was obtained. Weighted logistic regression analyses were used to investigate predictors of psychopathology. RESULTS In separate analyses of specific types of child psychopathology, different risk factors emerged as significant. Low-level parental occupation and having foreign-born parents were predictive of conduct disorders, and living in a single-parent family and a having a life event were the most important predictors of mood and anxiety disorders. Furthermore, CBCL-based ratings at 5 to 6 years of age corresponded well with interview-defined diagnoses 1.5 years later. CONCLUSIONS Investigation of psychosocial risk factors and CBCL scores at the age of 5 to 6 years could be helpful in predicting child psychopathology and could help identify children at risk, in order to provide them with timely attention.

Factors affecting the relation between parental education as well as occupation and problem behaviour in Dutch 5- to 6-year-old children

Background: This study investigated whether problem behaviour in 5- to 6-year-old children is related to parental education and occupation. It also analysed the contribution of correlating factors to explain this association. Method: The Child Behaviour Checklist was administered to a large community sample of 1317 children who were in the 1st year of normal primary school in the Netherlands. Outcome measures were total problem score, and externalising and internalising scale scores. Results: Results of the logistic regression analyses indicated that higher rates of reported behaviour problems were significantly associated with low parental education and occupation. These associations were mediated by low maternal age at delivery and single-parent families. The number of children in a family and physical illness of the parents did not contribute to these associations. Conclusions: Parental education and occupation have a large impact on the mental health of young children. Psychosocial and biological factors are possible explanations for this phenomenon.
