Mental Well-being and General Health in Adolescents with Asthma: The Prevention and Incidence of Asthma and Mite Allergy Birth Cohort Study

OBJECTIVES

To assess whether adolescents with asthma experience a lower mental well-being and lower general health than their peers without asthma.

STUDY DESIGN

Data from the Prevention and Incidence of Asthma and Mite Allergy study were used. At the ages of 11, 14, 17, and 20 years, 2651, 2522, 2094, and 2206 participants, respectively, completed questionnaires. Their parents completed questionnaires at the ages of 11 (n = 2660), 14 (n = 2338), and 17 years (n = 1872). Asthma was defined according to the Mechanisms of the Development of Allergy criteria. Mental well-being was measured using the Mental Health Index-5 and was reported by the adolescents. General health, measured on a 4-point Likert scale, was reported by the adolescents and their parents. We estimated associations of asthma with mental well-being and perceived general health using generalized estimating equations.

RESULTS

At ages 11, 14, 17, and 20 years, 6.7%, 6.9%, 5.0%, and 6.6%, respectively, of the adolescents had asthma. Adolescents with asthma did not score differently on the Mental Health Index than their peers without asthma. Adolescents with asthma were less likely to experience good or excellent health than their peers without asthma (aOR, 0.37; 95% CI, 0.26-0.51 for intermittent asthma and 0.33; 95% CI, 0.25-0.41 for persistent asthma). These results remain similar across the different ages.

CONCLUSIONS

The mental well-being of adolescents with asthma is similar to that of their peers without asthma, although adolescents with asthma are less likely to perceive a good or excellent general health.

Physical and psychosocial quality of life in children with overweight and obesity from Sri Lanka

Background

While childhood obesity is rising rapidly in South Asia, there is limited research on quality of life (QoL) of children with overweight and obesity from the region. This study assessed physical and psychosocial QoL in Sri Lankan children attending a specialized obesity clinic, from both children’s and parents’ perspective, and modifiable social factors affecting QoL.

Methods

We performed cross-cultural translation of the Pediatric Quality of Life Inventory (PedsQL™) 4.0 (Child-Self Report and Parent-Proxy forms), and assessed self-reported and parental-perception of physical and psychosocial QoL in 8–12 year-olds with overweight and obesity (n=110), referred for obesity management at a tertiary-care children’s hospital in Sri-Lanka. Body mass index (BMI) and pre-selected social factors affecting QoL were also assessed. Data were analyzed by non-parametric tests (Mann-Whitney U test, Wilcoxon test and Spearman correlation).

Results

The median physical QoL was lower than psychosocial QoL (78.1vs81.7, p=0.032) and physical QoL was inversely correlated with BMI. Parental-perception of children’s physical and psychosocial QoL correlated with child-reported QoL, but was lower. Being bullied (p=0.001) and not getting regular exercise (p=0.031) were associated with lower psychosocial QoL. Both physical and psychosocial QoL were lower in children having difficulties in finding suitable clothes (p< 0.001).

Conclusions

Children with overweight and obesity from Sri Lanka appeared to have greater impairment of physical QoL than psychosocial QoL. Higher BMI, bullying, lack of regular exercise and lack of suitable clothing, negatively affected QoL. Potential strategies to improve QoL include promoting regular exercise, addressing bullying and promoting availability of children’s clothes in larger sizes to fit children with overweight and obesity.

Reliability and validity of the Thai pediatric quality of life inventory™ 3.0 neuromuscular module

Background

Neuromuscular disorders (NMDs) are chronic illnesses that adversely impact the lives of patients and their families. The Pediatric Quality of Life™ 3.0 Neuromuscular Module (PedsQL™ 3.0 NMM) was designed to assess health-related quality of life (HRQoL) among children with NMDs. The objective of this cross-sectional study is to evaluate the reliability and validity of the PedsQL™ 3.0 NMM Thai version.

Methods

Formal permission to translate the PedsQL™ 3.0 NMM into Thai language was granted by the inventor, and the translation process followed linguistic translation guidelines. The PedsQL™ 3.0 NMM Thai version was administered to children with NMD and their parents/caregivers at the Division of Neurology, Department of Pediatrics, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. Re-test was performed within 2–4 weeks after the initial test.

Results

One hundred and three children with NMD and their parents or caregivers were enrolled. Internal reliability as measured by Cronbach’s alpha was > 0.7 (total score: child α = 0.88, parent α = 0.91). Test-retest reliability showed good agreement with an intraclass correlation coefficient (ICC) of 0.69 and 0.82 for the total score of the child report and the parent report, respectively. The mean (SD) quality of life total score for the child self-report was 74.9 (13.9) among ambulatory patients, and 60.7 (15.2) among non-ambulatory patients (maximum quality of life score is 100). The mean total quality of life score for the parent proxy-report was 70 (14.5) among ambulatory patients, and 55.2 (18.3) among non-ambulatory patients. The child total score was in good agreement with the parent/caregiver total score.

Conclusions

PedsQL™ 3.0 NMM Thai version is a reliable and valid measure of HRQoL in Thai children with NMDs.

Health related quality of life among children with transfusion dependent β-thalassaemia major and haemoglobin E β-thalassaemia in Sri Lanka: a case control study

Background

Thalassaemia is a chronic disease without an effective cure in a majority. The clinical management has improved considerably during recent years; however, minimal attempts are made to up lift the quality of life among patients, especially in developing countries. Here we aim to describe and compare and to determine factors associated with health related quality of life among patients with transfusion dependent β-thalassaemia major and haemoglobin E β-thalassemia in Sri Lanka.

Methods

A case control study was conducted in the three largest thalassaemia centres of Sri Lanka. All patients with transfusion dependent β-thalassaemia (β-thalassaemia major and haemoglobin E β-thalassaemia) aged 5–18 years were recruited as cases whilst a randomly selected group of children without chronic diseases were recruited as controls. Socio-demographic and clinical data were collected using an interviewer-administered questionnaire and health related quality of life was measured using the validated Paediatric Quality of Life Inventory Version 4.0.

Results

Two hundred and seventy one patients with transfusion dependent β-thalassaemia (male-49.1%; mean age- 10.9 ± 3.6 years) and 254 controls (male-47.2%; mean age- 10.4 ± 3.5 years) were recruited. Mean health-related quality of life scores were significantly lower in patients compared to controls (72.9 vs. 91.5, p < 0.001). Of the patients, 224 (84%) had β-thalassaemia major and 43 (16%) had haemoglobin E β-thalassaemia. Quality of life scores in psychological health (p < 0.05), emotional functioning (p < 0.05) and social functioning (p < 0.05) were significantly lower in patients with haemoglobin E β-thalassaemia compared to β-thalassaemia major. Splenectomy (p < 0.05), short stature (p < 0.05), under nutrition (p < 0.05) and longer hospital stays (p < 0.05) were significantly associated with lower quality of life scores.

Conclusions

Despite improvements in management, the quality of life among patients with β-thalassaemia still remains low. This is more pronounced in the subset of patients with haemoglobin E β-thalassaemia. Splenectomy, short stature, undernutrition and longer hospital stays were significantly associated with poor quality of life. It is timely, even in developing countries, to direct emphasis and to take appropriate steps to improve standards of living and quality of life of patients with β-thalassaemia.

Reliability and validity of the Thai version of the Pediatric Quality of Life inventory™ 3.0 Duchenne Muscular Dystrophy module in Thai children with Duchenne Muscular Dystrophy

Background

Duchenne Muscular Dystrophy (DMD) is the most common genetic neuromuscular disorder in children. This chronic illness may impact the physical, family, social and school life of affected children and their families. These impacts can be assessed using a disease-specific measure of health-related quality of life (HRQOL). The Pediatric Quality of Life Inventory™ (PedsQL™) 3.0 DMD Module is designed to assess quality of life in children with DMD. This study aimed to evaluate the reliability and validity of the Thai version of the PedsQL™ 3.0 DMD Module in Thai children aged 5–18 years.

Method and materials

The Thai translation of the PedsQL™ 3.0 Duchenne Muscular Dystrophy Module was performed in accordance with established guidelines using forward-back translation and was approved by the creator of the instrument. The Thai version of the scale was administered to children with DMD and their parents at the neuromuscular clinic at Siriraj Hospital and during the annual DMD Day meeting. Psychometric properties were established, and a re-test was performed within 2–4 weeks.

Results

Fifty-six children were enrolled. An acceptable level of internal reliability was achieved, as measured by α > 0.7 (total score: child report α = 0.88, parent report α = 0.92). Test-retest reliability showed good agreement, with the following intraclass correlation coefficients (ICCs) for the total score (calculated using all subscales from the child reports and parent reports): child report ICCs = 0.74 and parent report ICCs = 0.88. The mean total scale score was 66.03 for ambulatory children and 55.87 (P = 0.08) for non-ambulatory children according to child self-reports and 70.01 (ambulatory) and 54.29 (non-ambulatory) (P ≤ 0.01) according to parent proxy reports. The child self-reports were in acceptable agreement with the parent proxy reports for most subscales (ICC range 0.49–0.81).

Conclusions

The PedsQL™ 3.0 DMD Module Thai version is a reliable and valid measure of disease-specific health-related quality of life in Thai children with Duchenne muscular dystrophy.

Nonoperative treatment of acute appendicitis in children: A feasibility study

PURPOSE

Nonoperative treatment of acute appendicitis appears to be feasible in adults. It is unclear whether the same is true for children.

METHODS

Children 5-18 years with <48 h symptoms of acute appendicitis were offered nonoperative treatment: 2 doses of piperacillin IV, then ampicillin/clavulanate ×1 week. Treatment failure (worsening on therapy) and recurrence (after completion of therapy) were noted. Patients who declined enrollment were asked to participate as controls. Cost-utility analysis was performed using Pediatric Quality of Life Scale (PedsQL®) to calculate quality-adjusted life month (QALM) for study and control patients.

RESULTS

Twenty-four patients agreed to undergo nonoperative management, and 50 acted as controls. At a mean follow-up of 14 months, three of the 24 failed on therapy, and 2/21 returned with recurrent appendicitis at 43 and 52 days, respectively. Two patients elected to undergo an interval appendectomy despite absence of symptoms. Appendectomy-free rate at one year was therefore 71% (C.I. 50-87%). No patient developed perforation or other complications. Cost-utility analysis shows a 0.007-0.03 QALM increase and a $1359 savings from $4130 to $2771 per nonoperatively treated patient.

CONCLUSION

Despite occasional late recurrences, antibiotic-only treatment of early appendicitis in children is feasible, safe, cost-effective and is experienced more favorably by patients and parents.

Quality of life in pediatric asthma patients and their parents: a meta-analysis on 20 years of research

INTRODUCTION

This meta-analytic review was conducted to estimate the magnitude of quality of life (QoL) impairments in children/adolescents with asthma and their parents.

METHOD

A systematic search in four electronic databases revealed 15 quantitative studies published between 1994-2013 that directly compared the QoL of 7- to 18-year-old asthma patients/parents to community/healthy controls. Pooled mean differences (MD) with 95% CI were estimated using the inverse-variance random-effects method.

RESULTS

Pediatric asthma patients (n = 1797) presented lower overall QoL (MD = -7.48, CI: -10.67/-4.29), physical functioning (MD = -9.36, CI: -11.85/-6.86), psychological functioning (MD = -5.00, CI: -7.17/-2.82) and social functioning (MD = -3.76, CI: -5.80/-1.72), compared to controls (n = 13,266). For parents (666 cases and 7328 controls), asthma was associated with lower physical functioning (MD = -10.15, CI: -12.21/-8.08). Between-studies heterogeneity was explained by type of informant and selection of controls.

CONCLUSION

The ascertainment of the magnitude of QoL impairments and the most affected QoL dimensions for pediatric asthma patients/parents may contribute to the outlining of realistic goals for multidisciplinary interventions in healthcare settings and evaluate its cost-effectiveness.
