Bullying and victimization among 8-year-old children: a 16-year population-based time-trend study

Health Care Utilisation by Bullying Victims: A Cross-Sectional Study of A 9-Year-Old Cohort in Ireland

Children frequently refrain from disclosing being bullied. Early identification of bullying by healthcare professionals in children may prevent adverse health consequences. The aim of our study was to determine whether Health Care Utilisation (HCU) is higher in 9-year-olds who report being bullied and factors influencing type of HCU. The study consists of cross-sectional surveys of Child Cohort of Irish National Longitudinal Study of Children (Wave 1), 8,568 9-year-olds, and their carers. Being bullied was assessed by a self-reported questionnaire completed by children at home. HCU outcomes consisted of the following: visits to GP, Mental Health Practitioner (MHP), Emergency Department (ED), and nights in hospital by parent interview. Bivariate logistic regression and gender-stratified Poisson models were used to determine association. Victimisation by bullying independently increased visits to GP (OR 1.13, 95% confidence interval (CI): 1.03 to 1.25; p = 0.02), MHP (OR 1.31, 95% CI: 1.05 to 1.63; p = 0.02), though not ED visits (OR 0.99, 95% CI: 0.87 to 1.13; p = 0.8) or nights in hospital (OR 1.07 95% CI: 0.97 to 1.18; p = 0.2), adjusting for underlying chronic condition(s) and socio-demographic confounders. Victimised girls made higher GP visits (RR 1.14, 95% CI: 1.06 to 1.23; p < 0.001) and spent more nights in hospital (RR 1.10, 95% CI: 1.04 to 1.15; p < 0.001). Victimised boys were more likely to contact MHPs (RR 1.21, 95% CI: 1.02 to 1.44; p = 0.03). 9-year-old bullied subjects were more likely to utilise primary care services than non-bullied 9-year-olds. Different HCU patterns were observed according to gender and gender differences in the presentation of victimisation. Our findings may lead to the development of clinical practice guidelines for early detection and appropriate management of bullied children.

Trends in bullying victimization in Scottish adolescents 1994-2014: changing associations with mental well-being

Objectives

Bullying victimization among schoolchildren is a major public health concern. This paper aims to analyse the changing associations over two decades between bullying victimization and mental well-being in a representative Scottish schoolchildren sample.

Methods

Data were collected in six rounds of the cross-sectional Health Behaviour in School-aged Children study in Scotland, with 42,312 adolescents (aged 11, 13 and 15 years). Logistic and linear regressions were used to examine changes in the association between bullying victimization and mental well-being.

Results

The prevalence of bullying victimization rates in Scotland increased between 1994 and 2014 for most age–gender groups, apart from 13-year-old boys and 15-year-old girls. Over time, female victims reported less confidence and happiness and more psychological complaints than their non-bullied counterparts. This worsening effect over time was not observed in boys.

Conclusions

Overall, our evidence indicates that the associations between bullying victimization and poor mental well-being strengthened overtime for bullied girls. This finding might partly explain the observed deterioration in mental health indicators among Scottish adolescent girls.

Annual research review: Secular trends in child and adolescent mental health

BACKGROUND

Child and adolescent mental health problems are common, associated with wide-ranging functional impairments, and show substantial continuities into adult life. It is therefore important to understand the extent to which the prevalence of mental health problems has changed over time, and to identify reasons behind any trends in mental health.

SCOPE AND METHODOLOGY

This review evaluates evidence on whether the population prevalence of child and adolescent mental health problems has changed. The primary focus of the review is on epidemiological cross-cohort comparisons identified by a systematic search of the literature (using the Web of Knowledge database).

FINDINGS

Clinical diagnosis and treatment of child and adolescent psychiatric disorders increased over recent decades. Epidemiological comparisons of unselected population cohorts using equivalent assessments of mental health have found little evidence of an increased rate of ADHD, but cross-cohort comparisons of rates of ASD are lacking at this time. Findings do suggest substantial secular change in emotional problems and antisocial behaviour in high-income countries, including periods of increase and decrease in symptom prevalence. Evidence from low- and middle-income countries is very limited. Possible explanations for trends in child and adolescent mental health are discussed. The review also addresses how cross-cohort comparisons can provide valuable complementary information on the aetiology of mental illness.
