Health-related quality of life in children and adolescents: Current normative data, determinants and reliability on proxy-report

Associations among COVID-19 Family Stress, Family Functioning, and Child Health-Related Quality of Life through Lifestyle Behaviors in Children

The COVID-19 pandemic has resulted in lasting effects on children, necessitating a thorough understanding of its impact for effective recovery planning. This study investigated the associations among COVID-19 family stress, family functioning, children's lifestyle behaviors (i.e., healthy food intake, unhealthy food intake, physical activity, and screen time), and their health-related quality of life (HRQOL). Data from a 2022 survey of parents with children aged 5 to 12 (mean age of boys: 8.36, mean age of girls: 7.76) in the United States through the online Prolific platform were analyzed using path analysis and gender-based multi-group analysis. The results showed an inverse relationship between family stressors and functioning (β = -0.39, p < 0.05). COVID-19 family stress was negatively related to child physical HRQOL (β = -0.20, p < 0.05) but not psychosocial HRQOL. Family functioning showed a positive relation with child healthy food intake (β = 0.26, p < 0.05) and a negative relation with unhealthy diet consumption (β = -0.27, p < 0.05), while no significant associations were found with child physical activity and screen time. Family functioning was indirectly associated with both types of HRQOL through the child's eating patterns. These relationships were more pronounced for girls. The findings point to a complex interplay between family stress and functioning, dietary habits, and the HRQOL of children during the COVID-19 pandemic, particularly concerning girls' food intake and well-being.

Cross-sectional and longitudinal relationships between cardiorespiratory fitness and health-related quality of life in primary school children in England: the mediating role of psychological correlates of physical activity

AIMS

The aims were (1) to analyse the cross-sectional and longitudinal associations between children's cardiorespiratory fitness (CRF) and health-related quality of life (HRQoL) and (2) to examine whether these associations were mediated by physical activity self-efficacy and physical activity enjoyment.

METHODS

This study involved 383 children (10.0 ± 0.5 years) recruited from 20 primary schools in northwest England. Data were collected on two occasions 12 weeks apart. The number of laps completed in the 20-m Shuttle Run Test was used as the CRF indicator. HRQoL was assessed using the KIDSCREEN-10 questionnaire. Physical activity self-efficacy and enjoyment were assessed with the social-cognitive and Physical Activity Enjoyment Scale questionnaires, respectively. Linear mixed models with random intercepts (schools) assessed associations between CRF and HRQoL cross-sectionally, and longitudinally. Boot-strapped mediation procedures were performed, and indirect effects (IE) with 95% confidence intervals (CI) not including zero considered as statistically significant. Analyses were adjusted for sex, time of the year, socioeconomic status, waist-to-height ratio, maturation, and physical activity.

RESULTS

CRF was cross-sectionally associated with HRQoL (β = 0.09, 95% CI = 0.02, 0.16; p = .015). In the longitudinal analysis, CRF at baseline was associated with HRQoL at 12 weeks after additionally controlling for baseline HRQoL (β = 0.08, 95% CI = 0.002; p = .15, p = .045). Cross-sectionally, physical activity self-efficacy and enjoyment acted individually as mediators in the relationship between CRF and HRQoL (IE = 0.069, 95% CI = 0.038; p = .105 and IE = 0.045, 95% CI = 0.016; p = .080, respectively). In the longitudinal analysis, physical activity self-efficacy showed a significant mediating effect (IE = 0.025, 95% CI = 0.004; p = .054).

CONCLUSION

Our findings highlight the influence of CRF on children's psychological correlates of physical activity and their overall HRQoL.

Translation, cultural adaptation and validation of the German Quality of Life in Epidermolysis Bullosa (QOLEB) questionnaire

Epidermolysis bullosa (EB) is a rare disease characterised by skin fragility and a wide variety of symptoms. The Quality of Life in Epidermolysis Bullosa (QOLEB) score is an English 17-item EB-specific validated measurement tool with two dimensions: functioning and emotions. The aim of this cross-sectional study was to develop and validate a culturally adapted German QOLEB. The following steps were carried out: translation, expert evaluation, back translation, linguistic and cultural adaptation, sample-based psychometric testing and evaluation. Data analysis was performed with n = 46 patients across all EB types. The reliability and internal consistency of the translated German QOLEB were excellent (α = 0.901). Regarding convergent validity, the QOLEB correlated highly with the iscorEB (r = 0.879; p < 0.001). Structural similarity with the English original version was confirmed through exploratory factor analysis. In conclusion, the German QOLEB demonstrates internal reliability and construct validity and is suitable to assess the quality of life in German-speaking EB patients.

The Effects of Injury Type on Health-Related Quality of Life in Youth Athletes: A Cross-Sectional Analysis

OBJECTIVE

The relationship between health-related quality of life (HRQoL) and injury type has not been analyzed for young athletes. We hypothesized that there would be no difference in HRQoL between injured athletes, injured nonathletes, and normative data for healthy youth (NDHY) or among athletes with acute, overuse, or concussion injuries.

DESIGN

Cross-sectional clinical cohort.

SETTING

Primary care sports medicine clinics at 3 academic institutions.

PARTICIPANTS

Patients aged 8 to 18 years presenting with injury.

INDEPENDENT VARIABLES

Injury type and athletic participation.

MAIN OUTCOME MEASURES

Health-related quality of life measured 1 month after injury through the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric-25 v2.0 assessed pain interference, peer relationships, depression, fatigue, anxiety, and mobility. One-way analysis of variance was performed with P values of <0.05 considered significant. Concussion Learning Assessment and School Survey (CLASS) evaluated academic performance.

RESULTS

Three hundred fifty-seven patients (36% male), with average age of 14.2 years, completed HRQoL and CLASS surveys following injury. There were 196 overuse injuries (55%), 119 acute injuries (33%), and 42 concussions (12%). Ninety-four percent were athletes. Six percent were nonathletes; 90.5% of concussed patients reported grades worsening. Concussed athletes reported more fatigue (P = 0.008) compared with other injury types but no worse than NDHY. Athletes with overuse injuries had lower mobility (P = 0.005) than other injury types and NDHY. Patients with lower HRQoL were female, older age, or required surgery. No other domains had significant differences by injury type nor did HRQoL differ between the athletes, nonathletes, and NDHY.

CONCLUSIONS

With the exception of injuries requiring surgery, HRQoL of injured young athletes was similar to NDHY in most domains.

Psychosocial Well-Being of Siblings of Pediatric Patients in Palliative Home Care

CONTEXT

Despite the proposed high burden of siblings of children and adolescents with life-limiting conditions receiving pediatric palliative care (PPC) at home, little is known about their psychosocial well-being.

METHODS

In this prospective, cross-sectional trial siblings of patients of a large pediatric palliative home care team were asked to answer the KINDL survey of health-related quality of life, the strengths and difficulties questionnaire (SDQ) to assess problems and resources of children and adolescents as well as the LARES questionnaire, a potential tool for early screening of distress in siblings of chronically ill children. The results of the KINDL total and subdomains as well of the SDQ-subdomains were compared to recent German normative data using multiple t-tests.

RESULTS

In total, 44 siblings (28 female; age 7-18 years, mean 11.8 ± 3.03) of 29 families participated in this study. The subgroup which matches the age range of current normative data of 11-17 years old siblings (n = 25) reported a significant lower total quality of life as measured by KINDL in comparison to normative data. Subscale analyses revealed a significant lower physical and psychological well-being and self-esteem. Siblings of PPC patients yielded significant higher scores in the subdomain prosocial behavior compared to normative data as measured by the SDQ.

CONCLUSIONS

Siblings of children receiving PPC in a home care setting are at risk for a relevant impairment of their health-related quality of life. Future studies should address the potential for possible interventions specific for this population-at-risk.

Cross-sectional and prospective associations between children's 24-h time use and their health-related quality of life: a compositional isotemporal substitution approach

Background

Promoting active, balanced lifestyles among children may be an important approach to optimising their health-related quality of life (HRQoL). However, the relationships between children's movement behaviours and HRQoL remain unclear.

Methods

We examined the associations between movement behaviours (sleep, inactivity, light and moderate-to-vigorous intensity physical activity) assessed using accelerometers at ages 8 and 10 years and self-reported HRQoL scores (overall, and physical and emotional well-being, self-esteem, relationship with family and friends, and school functioning domains) at age 10 years among 370 children in a local birth cohort using compositional isotemporal substitution techniques.

Findings

Cross-sectionally, light and moderate-to-vigorous intensity physical activities were associated with better self-esteem (β = 15.94 [2.71, 29.18]) and relationship with friends (β = 10.28 [3.81, 16.74]) scores respectively. Prospectively, inactivity was associated with lower overall HRQoL (β = -10.00 [-19.13, -0.87]), relationship with friends (β = -16.41 [-31.60, -1.23]) and school functioning (β = -15.30 [-29.16, -1.44]) scores, while sleep showed a positive trend with overall HRQoL (β = 10.76 [-1.09, 22.61]) and school functioning (β = 17.12 [-0.87, 35.10]) scores. Children's movement behaviours were not associated with their physical and emotional well-being, or relationship with family scores. The isotemporal substitution analyses suggest that increasing time spent in physical activity and/or sleep at the expense of inactivity may benefit children's HRQoL.

Interpretation

Our findings suggest that sleep and physical activity may be associated with better HRQoL, with the inverse for inactivity. However, the relationship between children's movement behaviours and HRQoL is complex and warrants further research.

Comparing self-reported quality of life in youth with bipolar versus other disorders

OBJECTIVES

This study benchmarks quality of life (QoL) of youth with bipolar disorder (BD) against healthy youth, youth with chronic medical conditions, and youth with other psychiatric disorders. The relative impacts of depressive, (hypo)manic, mixed, and externalizing symptoms on QoL are tested for youth with BD.

METHOD

In total, 657 youth completed the Schedule for Affective Disorders and Schizophrenia for Children (KSADS), the KSADS depression and mania scales, the Parent General Behavior Inventory (PGBI), and the Child Behavior Checklist (CBCL). Youth-reported QoL was determined by the Revised Children Quality of Life Questionnaire (KINDL) and was compared to healthy youth, youth with chronic medical conditions, and youth with other psychiatric disorders.

RESULTS

Youth with BD reported poorer QoL overall and on most subscales compared to healthy youth, youth with chronic medical conditions, youth with behavior disorders, and youth with other non-behavior/non-mood disorders. QoL in youth with BD did not differ significantly from QoL in youth with unipolar depression. Parent-report and interview-rated depressive symptoms were associated with decreases in Total QoL and all QoL subscales except Family. Externalizing symptoms were associated with decreases in Family QoL and increases in Friend QoL, and (hypo)manic symptoms were associated with increases in Emotional Well-Being QoL.

CONCLUSIONS

Depressive symptoms may drive the decline in QoL causing youth with BD to rate their QoL worse than healthy youth, youth with chronic medical conditions, and youth with behavior disorders, but not worse than youth with unipolar depression.

Changes in behavior and quality of life in German young children during the COVID-19 pandemic-results from the COVID kids bavaria study

Introduction

The COVID-19 pandemic with its containment measures such as closures of schools and daycare facilities led to numerous restrictions in daily life, putting developmental opportunities and health-related quality of life in children at risk. However, studies show that not every family was impacted equally by the pandemic and that this exceptional health and societal situation reinforced pre-existing health inequalities among the vulnerable. Our study aimed at analyzing changes in behavior and health-related quality of life of children attending elementary schools and daycare facilities in Bavaria, Germany in spring 2021. We also sought to identify associated factors contributing to inequalities in quality of life.

Methods

Data from a multi-center, open cohort study ("COVID Kids Bavaria") conducted in 101 childcare facilities and 69 elementary schools across all electoral districts of Bavaria were analyzed. Children attending these educational settings (aged 3-10 years) were eligible for participation in a survey on changes in behavior and health-related quality of life. The KINDL^R questionnaire (based on children's self-report and parental report) was administered about one year after the onset of the pandemic (spring 2021). Descriptive and logistic regression analyses and comparisons to pre-pandemic KiGGS (German Health Interview and Examination Survey for Children and Adolescents) data were undertaken.

Results

Among respondents, a high percentage of parents reported changes in their children's eating and sleeping behavior, sports and outdoor activities as well as altered screen time. Health-related quality of life in KINDL^R analyses compared to pre-pandemic population averages were lower in all age groups (for 3-6-year-old KINDL^R-total score: COVID Kids Bavaria MD 74.78 ± 10.57 vs KiGGS data 80.0 ± 8.1; 7-10 years-old KINDL^R-total score: COVID Kids Bavaria MD 73.88 ± 12.03 vs KiGGS data 79.30 ± 9.0). No significant differences were detected with regard to associated factors, namely type of institution, sex of the child, migration background, household size and parental education.

Conclusion

These findings suggest a relevant impact of the COVID-19 pandemic on children's behavior and health-related quality of life one year after the onset of the pandemic. Further analyses in large-scale longitudinal studies are needed to determine the effects of specific pandemic or crisis associated factors contributing to health inequalities.

The Impact of ADHD on Maternal Quality of Life

Childhood attention-deficit/hyperactivity disorder (ADHD) is associated with substantial burden to caregiver quality of life (QoL). However, a paucity of work has focused on quantifying QoL among caregivers of adolescents with a history of ADHD. The purpose of the current study was (1) to quantify maternal QoL in a sample of mothers of adolescents with and without childhood ADHD; and (2) to examine predictors (i.e., parent and child characteristics and behavior) associated with maternal QoL. Participants included mothers of adolescents with (N = 110) and without ADHD (N = 90) ranging in age from 13 to 18 (M = 16.09, 92% male). The Quality Adjusted Life-Year (QALY) was used to calculate maternal QoL using two health domains (i.e., anxiety/depression and disruption in daily activities) commonly impacted by raising youth with ADHD. QALYs are valued monetarily to estimate disease burden. Mothers of adolescents with childhood ADHD experienced significantly worse QoL relative to mothers in the comparison group. Maternal depression, as well as adolescent age, ADHD status, and discipline problems significantly predicted lower levels of maternal QALY health status index, with ADHD being the strongest predictor. This is equal to a reduction in 1.96 QALYs when summed over the course of a child's lifetime and is associated with a loss of $98,000 to $196,000. Results of the investigation help to further elucidate the health impacts incurred by families of adolescents with ADHD and have important public health implications. Further, parental QoL should be considered when conceptualizing the financial and negative health impact of ADHD.

Health-related quality of life profile of Indonesian children and its determinants: a community-based study

Background

Assessing health-related quality of life (HRQOL) and its determinants in children may provide a comprehensive view of child health. The study aimed to assess the HRQOL in Indonesian children and its determinants.

Methods

We conducted a community-based cross-sectional study in the Sleman District of Yogyakarta Special Province, Indonesia, from August to November 2019. We recruited children aged 2 to 18 years old using the Sleman Health and Demography Surveillance System sample frame. We used the validated Indonesian version of Pediatric Quality of life Inventory™ (Peds QL™) 4.0 Generic core scale, proxy-reports, and self-reports, to assess the HRQOL.

Results

We recruited 633 proxies and 531 children aged 2–18 years. The mean total score of self-report and proxy-report were 89.9+ 8.5 and 93.3 + 6.4. There was a fair to moderate correlation between self-reports and proxy-reports, with intra-class correlation ranging from 0.34 to 0.47, all p < 0.001. Half of the children (49.4% from proxy-report and 50.1% from self-report) reported having acute illness during the last month. Based on proxy-reports, multivariate regression analysis demonstrated lower HRQOL for children with acute health problems, younger age, history of low birth weight, abnormal delivery, lower fathers’ educational level, and government-paid insurance for low-income families.

Conclusion

Sociodemographic determinants of a child’s HRQOL, acute health problems, and low birth weight were associated with lower HRQOL in the general pediatric population. In low- and middle-income countries where acute infections and low birth weight are still prevalent, its prevention and appropriate interventions should improve child health.

Move more - be happier? physical activity and health-related quality of life in children with congenital heart disease

OBJECTIVE

This cross-sectional study aimed to determine whether there is an association between objectively assessed physical activity (PA) and health-related quality of life (HRQoL) in children with CHD.

PATIENTS AND METHODS

From September 2017 to January 2021, 343 children with CHD (12.1 ± 3.3 years, 135 girls) provided valid PA data after a 7-day objective PA assessment. PA was evaluated as average daily steps and moderate-to-vigorous physical activity (MVPA) minutes assessed via wearable bracelet Garmin vivofit Jr. These children also completed the KINDL - a 24 Likert-scaled item questionnaires assessing HRQoL in the six dimensions physical well-being, emotional well-being, self-esteem, family, friends and everyday functioning.

RESULTS

Daily Steps (r = 0.166, P = .003) and daily MVPA minutes (r = 0.134, P = .017,) were both correlated to total KINDL score. Furthermore, both steps and MVPA were associated with the subscales physical well-being (steps: r = 0.165 p=.003; MVPA: r = 0.129, P = .022), friends (steps: r = 0.210, P < .001, MVPA: r = 0.179, P = .001), steps, and to everyday functioning (r = 0.142, P = .012). Logistic regression showed each MVPA minute increase conferred to a 1% increase in reporting better HRQoL (OR: 1.009 [95% CI: 1.002 - 1.017], P = .019).

CONCLUSIONS

PA was positively associated with HRQoL in children with CHD. Patients who move more are more likely to report better HRQoL. While the magnitude of this association needs to be further understood, continuous encouragement towards more PA seems to be crucial in a holistic approach to medical aftercare in children with CHD.

Health-Related Quality of Life and Frequency of Physical Activity in Spanish Students Aged 8-14

The study of health-related quality of life (HRQoL) in children and adolescents has important implications in terms of policy, education, and health. Data on the time spent in physical activity (PA) and in sedentary activities in this population are worrying. We aim to analyze possible differences in HRQoL and PA levels between sexes and age groups in Spanish students aged between 8 and 14 years, as well as to assess the relationship between HRQoL and the frequency of PA in this population. A total of 3197 participants (1610 boys and 1587 girls) from 8 to 14 years old were recruited. Mquality and Mapping Child Health Utility instrument (Chu9d) were used as HRQoL indicators. A medium positive association between PA and HRQoL concerning the Spanish school population was found. HRQoL was higher among students aged 8 to 12 than 13 to 14. Moreover, when children start secondary education, both sexes seem to lose the quality of life. Similarly, PA decreases among girls over the years, although it seems to increase among boys. Thus, PA levels and HRQoL are directly associated in Spanish schoolchildren aged between 8 and 14 years. However, this HRQoL decreases in children over the years. Practical implications include the need to support education and physical activity programs to improve HRQoL in children and adolescents.

Confirmatory factor analysis of the proxy version of Kidscreen-27 and relationships between health-related quality of life dimensions and body mass index and physical activity in young schoolchildren

•

The full Kidscreen-27 should be used with caution for young children.

•

Physical activity was positively associated with physical well-being.

•

Body mass was negatively associated with physical well-being.

•

Compared to older children, the youngest may have more negative school experiences.

The aim of the study was to perform a confirmatory factor analysis (CFA) to investigate the psychometric properties of the proxy version of Kidscreen-27 in order to determine whether the instrument can be used to assess health-related quality of life (HRQoL) in young children (five to six years of age). Furthermore, we aimed to examine the relationships between the HRQoL dimensions and the body mass index (BMI), physical activity (PA), age, and gender. Altogether, 276 children from schools in eastern Norway were included (September 2016). HRQoL was measured using the Kidscreen-27 proxy version. CFA was conducted to examine the factorial validity of the five-dimension instrument. Structural equation modelling was used to estimate the relationship between the independent variables and the HRQoL subscales that showed an acceptable fit; physical well-being, social support and peers, and school environment. PA was positively, and BMI negatively associated with physical well-being (p < 0.5). Parents of the youngest children reported more negatively on the school environment subscale (p < 0.5). The full 27-item proxy version of Kidscreen should be used with caution for children as young as five to six years as two of the subscales were found to have unsatisfactory factor loadings. The physical well-being, the social support and peers, and the school environment subscales can provide valid and valuable data for research and practice. Even though the associations are small, it is worrying that adverse relationships between PA and BMI and physical well-being are detectable in such a young sample as included here.

Quality of life in allergic rhinitis - children's and their parents' perspective in polish urban and rural population

BACKGROUND

Allergic rhinitis is a common chronic condition in the paediatric population. No reports regarding the quality of life in children with allergic rhinitis in the Polish population have been found in the available literature. The aim of this study was to assess and compare the quality of life in patients with allergic rhinitis reported by children and their parents living in a city and in rural areas, and to evaluate the possible relationships between the quality of life and the severity of symptoms.

METHODS

Two hundred and eight children with allergic rhinitis participated in the study (89 girls, aged 6-17, mean age 11.7 ± 3). Children were asked to evaluate their rhinitis symptoms by using two scales: the Total 4 Symptom Score and the Visual Analogue Scale. The quality of life assessment included the KINDL-R questionnaire.

RESULTS

Both for the T4SS and the VAS scale the severity of symptoms in children with seasonal rhinitis was significantly higher than in children allergic to perennial allergens. The quality of life total scores on the KINDL questionnaire was 45.6 ± 8.5 for the children and 73.7 ± 10.7 for the parents. In all the domains, except for physical health, the child's quality of life was rated significantly higher by parents than by children. The biggest discrepancy occurred in the domains: social contacts and family.

CONCLUSIONS

Allergic rhinitis can disrupt the quality of life. Parents tend to overestimate their children's quality of life comparing to the children's own assessment. The quality of life in children with allergic rhinitis correlated with the severity of the clinical symptoms of the disease. Evaluation of the quality of life in children is an essential issue in clinical investigation of patients with allergic rhinitis. It is of great importance to ask children themselves about their quality of life than rely only on parental opinion.

Peak nasal inspiratory flow in children with allergic rhinitis. Is it related to the quality of life?

INTRODUCTION AND OBJECTIVES

Allergic rhinitis (AR) is the most common allergic disease in childhood. Nasal obstruction is a typical symptom of AR, however, its quantification by clinical examination is difficult. To provide an objective assessment of nasal patency, the peak nasal inspiratory flow (PNIF) is used. Symptoms of AR have a noticeable impact on the quality of life. The aim of this study was to assess which factors may have an impact on PNIF values and to evaluate the possible relationships between PNIF and QoL in children with AR.

PATIENTS AND METHODS

We recruited patients aged 6-17 years (n = 208, 89 girls and 119 boys) with AR. All children underwent PNIF measurements. Parents and children completed KINDL-R generic questionnaires, to assess the quality of life of the children.

RESULTS

The average PNIF value was 98.9 ± 37.4 L/min. A very strong (p < 0.001) relationship between the PNIF value and height, age and weight of the child was observed. The sex of the patient has no influence on the PNIF value. We showed that PNIF values significantly increased with each attempt. The children assessed their QoL at 45.6 ± 8.5 points in the KINDL-R questionnaire and the parents rated their children's QoL at 73.7 ± 10.7 points. We observed a weak negative correlation between PNIF and the QoL based on the parents' assessment and the child's self-assessment.

CONCLUSIONS

PNIF values depend mostly on height, but also on the child's age and weight. A learning effect (significant increase in PNIF upon each attempt) was shown. Higher PNIF does not improve the QoL.

Current state of home-based exercise interventions in patients with congenital heart disease: a systematic review

Home-based exercise training is a promising alternative to conventional supervised training for patients with congenital heart disease (CHD). Even though the beneficial effect of exercise interventions is well established in patients with CHD, knowledge concerning variety and utility of existing programmes is still lacking. Therefore, the aim of this review is to give an overview about existing home-based exercise interventions in patients with CHD. A systematic search was performed in PubMed, Cochrane, Scopus and PEDro (2008–2018) for relevant clinical trials that provided any kind of home-based exercise with patients with CHD. All articles were identified and assessed by two independent reviewers. Seven articles with 346 paediatric CHD (18 months to 16 years) and five articles with 200 adults with CHD (21–41 years) were included. Most studies performed a supervised home-based exercise intervention with children and adolescents exercising at least three times per week with duration of 45 min for 12 weeks. Reported outcome measurements were health-related quality of life and physical activity, but mostly exercise capacity measured as peak oxygen uptake that improved in four studies (1.2%, 7%, 7.7%, 15%; p<0.05), walking distance in two (3.5%, 19.5%, p<0.05,) or walking time (2 min, p=0.003) in one. The dropout rates were high (15%), and compliance to the training programme was not reported in the majority of the studies (58%). Home-based exercise interventions are safe, feasible and a useful alternative to supervised cardiac rehabilitation for all age groups of patients with CHD. Nevertheless, training compliance represents a major challenge.

Examining boys' and girls' health-related quality of life from the first to the third year of upper secondary school: A prospective longitudinal study

AIM

To examine differences in health-related quality of life between boys and girls in the first and third years of upper secondary school.

DESIGN

Prospective longitudinal study.

METHODS

The KIDSCREEN-10 was used to assess health-related quality of life. Differences in health-related quality of life over time were estimated using a linear mixed-effects model for correlated measurements.

RESULTS

In the first-year boys (N = 168) and girls (N = 228) reported a mean health-related quality of life score of 76.3 (SD 10.7) and 69.8 (SD 11.5), respectively. In the third year, the mean health-related quality of life score for boys and girls was 73.5 (SD 12.4) and 65.7 (SD 13.3), respectively. Boys had a significant decrease in health-related quality of life mean score of -2.6 and girls a significant decrease of -3.8 (p < .001) over the 3-year period. There was no significant difference between boys' and girls' health-related quality of life changes (p = .39).

Quality of life in young people with congenital heart disease is better than expected

OBJECTIVES

Improved treatments for patients with congenital heart disease (CHD) have led to a growing interest in long-term functional outcomes such as health-related quality of life (HRQoL). Studies on HRQoL in children with CHD have contradicting results. Therefore, we compared HRQoL of children with CHD with that of current healthy peers and stratify CHD cases by severity and diagnostic subgroups.

METHODS

We included 514 patients (191 girls) aged 7-17 (12.9±3.1) years who were recruited at our institution between July 2014 and May 2017. The self-reported and age-adapted KINDL questionnaire was used to assess HRQoL. Patient data were compared with that of a recent control group of 734 healthy children (346 girls, 13.4±2.1 years).

RESULTS

Patients with CHD scored at least as high as healthy peers in HRQoL (CHD: 78.6±9.8; healthy: 75.6±10.1; P<0.001). After correction for sex and age, patients with CHD presented a 2.3-point higher HRQoL (P<0.001). The sex-specific and age-specific analyses showed that there were no differences between boys with and without CHD in childhood (P=0.255), but in adolescence, boys with CHD had on average 3.9-point higher scores (P=0.001), whereas girls with CHD had statistically higher HRQoL perception than healthy girls in childhood (4.2 points; P=0.003) and adolescence (4.2 points; P=0.005). There were no differences between the severity classes or diagnostic subgroups in the total HRQoL score or in the six subdomains.

CONCLUSION

The high HRQoL in young patients with CHD suggests that they can cope well with their disease burden. This holds true for all severity classes and diagnostic subgroups.

Parent-child Agreement on Health-Related Quality of Life in Children With Functional Constipation in Primary Care

OBJECTIVE

Functional constipation (FC) has a major impact on the health-related quality of life (HRQoL) of children. The aim of this study was to evaluate parent-child agreement on HRQoL in children (8-17 years) with FC in primary care.

METHODS

Children diagnosed with FC by their clinician were eligible. HRQoL was measured with the Defecation Disorder List (DDL, score 0-100), and the EuroQol-5-Dimension-Youth Visual Analogue Scale (EQ-5D-Y-VAS, scale 0-100). Parent-child agreement was examined with discrepancy scores, intraclass correlation coefficients and Bland-Altman plots.

RESULTS

Fifty-six children, median age of 10 years (IQR 8-12) and their parents were included. Parent-child agreement at a group level was good, with an intraclass correlation coefficient of 0.80 (95% confidence interval 0.67 to 0.88) for the DDL, and 0.78 (95% confidence interval 0.65 to 0.87) for the EQ-5D-Y-VAS. Mean discrepancy scores for the DDL and EQ-5D-Y-VAS were small: -2.6 and -2.9, implying that parents were slightly more positive about the HRQoL than their children. Bland-Altman plots showed considerable discordance between individual parent-child pairs. Limits of agreement were -19.7 and 14.6 for the DDL and -27.6 and 21.8 for the EQ-5D-Y-VAS.

CONCLUSIONS

There is good parent-child agreement on HRQoL in children with FC at group level. However, a substantial number of parent-child pairs differed considerably on their rating of the HRQoL of the child. Therefore, we recommend clinicians, if they want to have an impression of the impact of the FC on the HRQoL of the child, to ask both the child and the parent(s).

Quality of life in children and adolescents with bipolar I depression treated with olanzapine/fluoxetine combination

BACKGROUND

We examined the efficacy of olanzapine/fluoxetine combination (OFC) in improving health-related quality of life (QoL) in the treatment of bipolar depression in children and adolescents.

METHODS

Patients aged 10-17 years with bipolar I disorder, depressed episode, baseline children's depression rating scale-revised (CDRS-R) total score ≥40, Young Mania Rating Scale (YMRS) total score ≤15, and YMRS-item 1 ≤ 2 were randomized to OFC (6/25-12/50 mg/day olanzapine/fluoxetine; n = 170) or placebo (n = 85) for up to 8 weeks of double-blind treatment. Patients and parents completed the revised KINDL questionnaire for measuring health-related QoL in children and adolescents (KINDL-R) at baseline and endpoint. The mean change in CDRS-R total and item scores were used to compare improvement in symptomatology in patients taking OFC and placebo. Tests were 2-sided using a Type I error cutoff of 0.05, and no adjustments for multiple comparisons were made.

RESULTS

Baseline QoL as measured by the KINDL-R was substantially impaired relative to published norms for a healthy school-based sample. OFC-treated patients demonstrated an improvement over placebo at endpoint with respect to mean change from baseline in the patient-rated KINDL-R Self-esteem subscale score (p = 0.028), and in the parent KINDL-R ratings of emotional well-being (p = 0.020), Self-esteem (p = 0.030), and Family (p = 0.006). At endpoint, OFC-treated patients still had a lower QoL compared to the normative population. OFC showed significant improvement (p ≤ 0.05) versus placebo on the CDRS-R total score and on 7 of the 17 CDRS-R items.

CONCLUSIONS

Patients aged 10-17 years with an acute episode of bipolar depression and their parents reported greater improvements (parents noticed improvements in more areas than did their offspring) on some aspects of QoL when treated with OFC compared with placebo. However, after 8 weeks of treatment, KINDL-R endpoint scores remained lower than those of the, presumably healthy, control population.

Annual Research Review: Quality of life and childhood mental and behavioural disorders - a critical review of the research

BACKGROUND

An individual's subjective perception of well-being is increasingly recognized as an essential complement to clinical symptomatology and functional impairment in children's mental health. Measurement of quality of life (QoL) has the potential to give due weight to the child's perspective.

SCOPE AND METHODOLOGY

Our aim was to critically review the current evidence on how childhood mental disorders affect QoL. First, the major challenges in this research field are outlined. Then we present a systematic review of QoL in children and adolescents aged 0-18 years formally diagnosed with a mental and behavioural disorder, as compared to healthy or typically developing children or children with other health conditions. Finally, we discuss limitations of the current evidence base and future directions based on the results of the systematic review and other relevant literature.

FINDINGS AND CONCLUSIONS

The systematic review identified 41 eligible studies. All were published after the year 2000 and 21 originated in Europe. The majority examined QoL in neurodevelopmental disorders, including attention-deficit hyperactivity disorder (k = 17), autism spectrum disorder (k = 6), motor disorders (k = 5) and intellectual disability (k = 4). Despite substantial heterogeneity, studies demonstrate that self-reported global QoL is significantly reduced compared to typical/healthy controls across several disorders and QoL dimensions. Parents' ratings were on average substantially lower, casting doubt on the validity of proxy-report. Studies for large diagnostic groups such as depressive disorders, anxiety disorders, (early onset) schizophrenia and eating disorders are largely lacking. We conclude that representative, well-characterized normative and clinical samples as well as longitudinal and qualitative designs are needed to further clarify the construct of QoL, to derive measures of high ecological validity, and to examine how QoL fluctuates over time and is attributable to specific conditions or contextual factors.
