Predictors of health-related quality of life in chronically ill children and adolescents over time

Originalarbeiten / Original Articles. Die protektive Rolle von Selbstregulation für die gesundheitsbezogene Lebensqualität bei Jugendlichen mit einer chronisch körperlichen Erkrankung / The Protective Role of Self-Regulation for HRQOL of Adolescents with a Chronic Physical Health Condition

The Protective Role of Self-Regulation for HRQOL of Adolescents with a Chronic Physical Health Condition A physical chronic condition comes with many challenges and negatively impacts the healthrelated quality of life (HRQOL) of those affected. Self-regulation plays an important role in successfully coping with the demands of a chronic condition. In line with a resource-oriented approach, this study aimed to investigate themoderating effect of self-regulation on the relationship between disease severity andHRQOL. For this, 498 adolescents with cystic fibrosis, juvenile idiopathic arthritis, or type-1 diabetes aged of 12-21 years (M= 15.43, SD= 2.07) were recruited through three patient registers. Subjective disease severity, self-regulation (Brief Self-Control- Scale), andHRQOL (DISABKIDSChronicGenericMeasure)were examined at two time points (T₁ and T₂, one year apart). Cross-sectional analysis showed significant effects of subjective disease severity and self-regulation on HRQOL. Prospective analysis, in which HRQOL at T₁ was controlled for, revealed that disease severity only predicted emotion-related HRQOL at T₂; selfregulation emerged as a predictor for HRQOL subscales independence, emotion, inclusion, exclusion, and treatment. A significantmoderation effect of self-regulation was found on the relationship between disease severity and HRQOL emotion. Our results highlight the positive impact of self-regulation on quality of life, specifically in the context of chronic conditions and represent a starting point for prevention and intervention approaches.

Systematic Review of Health-Related Quality of Life Impact in Juvenile Localized Scleroderma

OBJECTIVE

The prevalence and types of psychosocial complications of juvenile localized scleroderma (JLS), also known as morphea, an inflammatory and sclerosing disease involving the skin, fascia, muscle, and bone, are poorly understood.

METHODS

We performed a systematic review of literature published between 2000 and 2020 in PubMed, EMBASE, the Cochrane Skin Group Specialized Register, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature using the search terms "scleroderma, localized," "Morphea," "anxiety," "depression," "resilience," "social stigma," "quality of life," "mood," or "stress" and limited the search to pediatric patients and English language. Patient demographics, characteristics of JLS, and comorbidities were extracted. The outcomes included measures of health-related quality of life (HRQoL), psychosocial functioning, evaluation of self-perception, and the treatment burden of the study population. The protocol was registered with PROSPERO (CRD42021257124). Thematic synthesis generated descriptive analysis.

RESULTS

Thirteen studies fulfilled the inclusion criteria: three retrospective cohort studies, two prospective cohort studies, and eight cross-sectional studies. A total of 690 pediatric patients with JLS were included (n = 484 with linear scleroderma). Six studies used the Children's Dermatology Life Quality Index, reporting little to no effect on HRQoL. One study used the Health-Related Quality of Life in Children and Adolescents Questionnaire and did not find differences between children with JLS or atopic dermatitis and healthy controls. One study used a self-perception questionnaire that showed normal self-worth of patients with JLS. Two studies used focus groups, both reporting elevated levels of stress, decreased self-worth, "feeling different," and bullying/teasing in patients with JLS. These emotions were associated with skin symptoms (pain, itch, and tightness), physical limitations, and treatment burden.

CONCLUSION

Overall, quantitative studies did not report a statistically significant impairment in HRQoL in JLS. However, qualitative studies (focus groups) reported significant psychosocial impacts related to JLS. There is a need to develop a JLS-specific tool for the HRQoL evaluation of this population.

Living with a rare disease - experiences and needs in pediatric patients and their parents

BACKGROUND

A rare disease (RD) diagnosis and therapy can affect the family's quality of life and mental health. A lack of information and missing care options lead to helplessness and psychological stress within families. This work aims to identify patients' and parents' experiences in daily life and with the health care system as well as their needs and current pathways to psychosocial care to develop implementation strategies adapted to the families' needs.

METHODS

The present analysis is part of the national multicenter study "Children Affected by Rare Disease and Their Families-Network (CARE-FAM-NET)." We conducted semi-structured telephone interviews with children, adolescents, and young adults with RD (aged 12 to 21 years) and parents of children with RD (aged 0 to 17 years). We analyzed the transcribed and anonymized interviews using the method of focused interview analyses to identify previous experiences with medical and psychosocial care and possible needs for improvement and support.

RESULTS

Seventy-four parents of children with RD and 15 children, adolescents, and young adults with RD participated. Five main themes emerged. Daily life with an RD: RD affects the everyday and social life of the respondents, negatively impacting mental well-being. Experiences with the health care system: The long diagnostic path is stressful for families. Professionals' lack of information/education leads to inadequate care for those affected. Psychosocial support: Families do not know about psychosocial care services. In some cases, the families take advantage of psychosocial support services (such as support groups or advocacy groups), which are predominantly very helpful. Difficulties and barriers: Time, socio-legal and organizational problems burden families and lead to advantages in using psychosocial services. Improvements for patient-oriented support: Those affected wished for timely, preventive support (especially in administrative and socio-legal matters) and education regarding psychosocial care services.

CONCLUSION

RD represent a great challenge for all family members - patients, parents, and siblings. The patients' and parents' previous experiences in daily life, medical and psychosocial care show a need for target-group specific support, including training of health care professionals and low-threshold access care services and practical help for all family members.

Psychiatric comorbidities in children and adolescents with chronic urticaria

BACKGROUND

Chronic urticaria (CU) has been shown to impact patients' quality of life negatively and may coexist with psychiatric disorders. We systematically reviewed the published evidence of comorbid psychiatric disorders in children and adolescents with CU.

METHODS

A systematic review of studies published until February 2022 in PubMed, Google Scholar, and Scopus was performed. An a priori set of inclusion criteria was predefined for the studies to be included: (1) clear distinction between urticaria and other allergies; (2) precise distinction between acute and CU; (3) participants younger than 18 years old, exclusively; (4) use of appropriate standardized questionnaires, psychometric tools, and standard diagnostic nomenclature for the mental health and behavioral disorders diagnosis; and (5) manuscripts written or published in the English language.

RESULTS

Our search identified 582 potentially relevant papers. Only eight of them satisfied the inclusion criteria. Quantitative meta-analysis was not deemed appropriate, given the lack of relevant randomized control trials, the small number of relevant shortlisted, the small sample size of the patients included in each study, and the remarkable heterogeneity of the studies' protocols.

CONCLUSIONS

The included studies suggest an increased incidence of psychopathology among children and adolescents with CU as opposed to healthy age-matched individuals, but the data are scarce. Further research is required to clarify whether psychopathology is just a comorbid entity, the cause, or the consequence of CU. Meanwhile an interdisciplinary collaboration between allergists/dermatologists and psychiatrists is expected to substantially minimize CU burden and improve patients' quality of life.

Fathers' Experiences of Caring for a Child with a Chronic Illness: A Systematic Review

The prevalence of children living with chronic health conditions is increasing worldwide and can disrupt family roles, relationships, function, and parental involvement in family caregiving. The purpose of this systematic review was to explore fathers' experiences and involvement in caring for a child with a chronic condition. Systematic searches using seven databases were conducted. Study criteria included (1) peer-reviewed original research in English, Spanish, French, or Portuguese, (2) children less than 19 years of age with a chronic condition, (3) fathers (biological or guardian) as direct informants, and (4) outcomes addressing fathers' experience, perceptions, and/or involvement in the child's care. Data were synthesized from ten articles reflecting eight separate studies that utilized quantitative designs. Three areas of focus were identified: Family Functioning, Father's Psychological Health, and Need for Support. Data suggested increased involvement from the father in caring for their child with a chronic condition was associated with improved family functioning, increased anxiety and distress, decreased self-esteem, and increased need for support. This review revealed a paucity of data regarding fathers' experiences and involvement when caring for a child with a chronic condition, with that available primarily from developed countries. Rigorous empirical studies are needed to deepen understanding of how fathers are involved in the care of their child with a chronic condition.

Pediatric Psychology in a Urology Division: Unifying Complex Medical and Mental Health Treatment

PURPOSE OF REVIEW

Although pediatric psychology is heavily involved in many medical divisions, its involvement in a urology division is still relatively new and its role continuously evolving and growing.

RECENT FINDINGS

This article reviews the limited research on the use of psychology in a urology division, including psychosocial struggles across urology diagnoses, dysfunctional voiding, and anxiety surrounding medical procedures and surgery. Urinary diagnoses and presenting problems seen by pediatric psychologists and medical providers at an urban children's hospital are also included. Based on the complex conditions and varied presenting concerns in a urology division, potential assessments and future research are suggested to help gather data for this population moving forward and expand the literature on urology psychology.

The Predictive Role of Cognitive Emotion Regulation of Adolescents with Chronic Disease and Their Parents in Adolescents' Quality of Life: A Pilot Study

BACKGROUND

The purpose of this study was to investigate cognitive emotion regulation in adolescents with chronic illness and their parents.

METHODS

Eighty-five young people (mean = 15.86 years, standard deviation = ± 1.42, girls 65.88%) with chronic illnesses (inflammatory bowel disease n = 40 or type 1 diabetes n = 45), and their parents (mean = 46.06 years, 87.06% mother) completed the Cognitive Emotion Regulation Questionnaire (CERQ) for themselves and the Inventory of Quality of Life in Children and Adolescents (ILC) questionnaire adolescent and parent version. We conducted two hierarchical linear regression analyses with "enter" method. The CERQ scales and the diagnosis of chronic disease were chosen as independent variables, and the total ILC score in the first analysis and the ILC proxy score in the second analysis were chosen as dependent variables.

RESULTS

Among adolescents, cognitive emotion regulation strategies such as self-blame, positive reappraisal, and catastrophizing have been proven to be predictors of their own quality of life; however, parental self-blame was also found to be a predictor of adolescents' quality of life. Parental rumination and positive refocusing have been shown to be predictors of how parents rate their child's quality of life.

CONCLUSIONS

The present study sheds light on cognitive emotion regulation strategies in adolescents with chronic illness and their parents that have a significant impact on the development of young people's quality of life.

Shedding Light on the Lifestyle and Participation of Portuguese Adolescents with Chronic Conditions—Data from the HBSC 2018 Study

Variables associated with lifestyle can constitute either risk or protective factors for the development and progression of chronic conditions (CC). This study intends to explore the differences between adolescents with and without CC and between adolescents whose school participation is affected/not affected by the existing CC with regard to variables related to lifestyle (i.e., sleep, physical activity, BMI, and leisure). In addition, it also intends to analyze the influence of these variables (i.e., CC and lifestyle) regarding the adolescents’ quality of life (QoL). This work is part of the Portuguese HBSC 2018 study. A total of 8215 adolescents participated (52.7% female), with an average age of 14.36 years (SD = 2.28). The results showed that the adolescents with CC and whose school attendance and participation are affected by their CC exhibit more sleep difficulties (i.e., they experience lower sleep quality and have a higher degree of sleepiness), higher BMI levels (i.e., higher values of overweight and obesity), less participation in leisure activities, and a lower perception of QoL. A higher perception of QoL is associated with school participation unaffected by the existing CC, sleeping well, a low level of sleepiness, a more frequent practice of physical activity, a lower BMI, and a greater involvement in leisure activities. Adolescent health and well-being are a prominent issue in terms of public policies, with behavior and lifestyle playing a significant role in this domain. This message needs to be reinforced in regard to families, educators, healthcare professionals, and public sector policies, particularly concerning students with CC.

Basic Motor Competencies of (Pre)School Children: The Role of Social Integration and Health-Related Quality of Life

In (pre)school, children acquire and deepen their basic motor competencies (BMCs) and interact with peers and friends. BMCs are a central developmental goal in childhood and the prerequisite for participation in sportive aspects of social life. Both motor competencies and social integration are linked to children's health-related quality of life (HRQoL). The aim of the present study was to describe the connection between BMCs, social relationships, and aspects of HRQoL in (pre)school children. In this study, the BMCs of N = 1163 preschool children (M = 5.7 years, SD = 0.57, 52% boys) and N = 880 first and second graders (M = 7.5 years, SD = 0.58, 51% boys) were tested. The children's social integration was assessed by the teachers; the HRQoL was recorded from the parents' perspective. In both preschool and primary school, children with better BMCs also showed higher values in their social integration. Moreover, the results indicated a connection between BMCs and general HRQoL in primary school and BMCs and physical well-being in preschool. As BMCs, social integration, and HRQoL seem to be connected in (pre)school, this should be considered both from developmental and health-oriented perspectives, as well as for physical education (PE) lessons.

Understanding the impact of 'wish-granting' interventions on the health and well-being of children with life-threatening health conditions and their families: A systematic review

This review aimed to explore how wish-granting interventions impact on the health and well-being of children with life-threatening health conditions and their families, using any study design. Six electronic databases (Medline; PsycINFO; CINAHL; Embase; AMED and HMIC) were systematically searched to identify eligible research articles. Studies were critically appraised using a Mixed Methods Appraisal Tool. Findings were synthesized narratively. 10 papers were included, reporting studies conducted across five countries, published from 2007 to 2019. Study designs were diverse (four quantitative; two qualitative and four mixed method). Results indicated improvements to physical and mental health, quality of life, social well-being, resilience and coping for wish children, parents and siblings. In conclusion, wish-granting interventions can positively impact health and therefore should not be discouraged; however, more research is needed to define and quantify the impact of wish fulfilment and to understand how it can be maximized.

Determinants of Quality of Life in Children with Inborn Errors of Metabolism Receiving a Restricted Diet

OBJECTIVE

To investigate the determinants of quality of life (QoL) in children with inborn errors of metabolism with restricted diet (IEMRDs) using a single theory-based multidimensional model.

STUDY DESIGN

In this multicenter cross-sectional study, data from children aged 8-17 years with IEMRDs (except phenylketonuria) and their parents were collected from January 2015 to December 2017. Measurements included a child's self-reported QoL, self-rated behavioral problems and anxiety, and parental anxiety. Based on hypotheses from a literature-built theoretical model linking demographic, clinical, family environment, and psychosocial characteristics to QoL either directly or indirectly, associations of these factors with a child's self-rated QoL were examined using a structural equation modeling approach.

RESULTS

A total of 312 children (mean [SD] age, 12.2 [2.6] years; 51% boys [n = 160]) were included. Higher levels of trait anxiety and behavioral problems in children were the most important factors associated with poorer QoL (standardized path coefficients, -0.71 and -0.23, respectively). In addition, higher parent trait anxiety, younger age at diagnosis, and a disease requiring an emergency diet were associated with poorer QoL in these children. The final model fit the data closely according to conventional goodness-of-fit statistics and explained 86% of the QoL variance.

CONCLUSIONS

Psychosocial factors appear to be major determinants of QoL impairment in children with IEMRDs. These factors should be addressed in clinical practice as part of the global treatment plan for a child with IEMRD. Future studies based on a longitudinal design should consider coping strategies when exploring potential predictive factors of QoL.

Risk factors for impaired health-related quality of life in a cohort of pediatric patients with inborn metabolic diseases

In the last decade, health-related quality of life (HrQoL) has become an increasingly important outcome parameter in children and adolescents with chronic health conditions; among them are pediatric patients with inborn metabolic diseases (IMDs). Hence, knowledge on this topic is increasing, but findings on non-medical influences on the HrQoL of IMD patients are still scarce. In the present study, we retrospectively evaluated the self-reported generic HrQoL of a cohort of pediatric patients (ages 7 to 17 years) with diverse IMDs (n = 204) and explored associations between HrQoL and psychosocial and medical characteristics of the patients. We aimed to identify risk factors for impaired HrQoL to improve and tailor support for the patients and economize resources. Generic HrQoL was assessed with the KINDL-R questionnaire. We compared the HrQoL scores to published German normative data and analyzed the impact of demographic variables and intellectual and psychosocial functioning on the HrQoL. Moreover, we examined the influence of the diagnostic category and the health impairment (as judged by the physicians) on our patients' HrQoL. Overall, the HrQoL of the adolescent patients was comparable to the HrQoL of the norm group. Disorders of intellectual development, impaired psychosocial functioning, and a severe health impairment were associated with lower HrQoL scores.Conclusion: We recommend evaluating these factors in children and adolescents with IMDs to identify patients at risk for impaired HrQoL. What is Known: • Studies on HrQoL in pediatric patients with IMDs mainly focused on subgroups with specific diagnoses and found normal HrQoL in some of those subgroups. • In healthy children and adolescents as well as in pediatric patients with various chronic diseases, associations between psychosocial factors and HrQoL are well known. What is New: • Impaired psychosocial functioning, disorders of intellectual development, and a significant disease and/or treatment burden are risk factors for impaired HrQoL in pediatric patients with IMDs. • Evaluating these factors in children and adolescents with IMDs can help identify patients and families in need of enhanced psychological support.

Non-disease specific patient-reported outcome measures of health-related quality of life in juvenile idiopathic arthritis: a systematic review of current research and practice

Juvenile idiopathic arthritis (JIA), as a chronic condition, is associated with symptoms negatively impacting health-related quality of life (HRQL). Regarding growing interest in the implementation of the patient-reported outcome measures (PROMs), we aimed to review the non-disease specific PROMs addressing HRQL assessment, potentially useful in the clinical care of JIA and daily practice. A systematic literature search was conducted using MEDLINE/PubMed, Google Scholar, Scopus and Embase databases (1990 to 2021), with a focus on the recent 5-years period. Entry keywords included the terms: “children”, “adolescents”, “JIA”, “chronic diseases”, “HRQL”, “PROMs” and wordings for the specific tools. Several available PROMs intended to measure HRQL, non-specific to JIA, were identified. The presented outcomes differed in psychometric properties, yet all were feasible in assessing HRQL in healthy children and those with chronic diseases. Both EQ-5D-Y and PedsQL have already been tested in JIA, showing relevant reliability, validity, and similar efficiency as disease-specific measurements. For PROMIS® PGH-7 and PGH-7 + 2, such validation and cross-cultural adaptation need to be performed. Considering the future directions in pediatric rheumatology, the large-scale implementation of PROMIS® PGH-7 and PGH-7 + 2 in JIA offers a particularly valuable opportunity. The PROMs reflect the patient perception of the chronic disease and allow to understand child’s opinions. The PROMs may provide an important element of the holistic medical care of patients with JIA and a standardized tool for clinical outcomes, monitoring disease severity and response to treatment.

Socioeconomic Factors and Quality of Life Perceived by Parents and Children with Complex Chronic Conditions in Spain

Health-related quality of life of children with complex chronic conditions could be affected by sociodemographic factors. Most studies focus exclusively on the parents’ perceptions of quality of life. This study aimed to determine the health-related quality of life of these children, according to their parents and the children themselves. A cross-sectional study was developed on children aged over five years with complex chronic conditions. Health-related quality of life, educational attainment, and social status were evaluated. A total of 101 children were included with a mean age of 10.48 years, and 35.6% were female. The most frequent disease was oncological (28.7%). Children perceived a better health-related quality of life, compared to their parents’ assessment: median difference −8.4 (95%CI: −9.2 to −3.8). Moreover, differences were observed by socioeconomic factors. Parents and children with complex chronic conditions perceive differently the health-related quality of life. Social determinants associate with an uneven perceived quality of life.

Quality of Life of Children with Allergic Disease: The effect of Depression and Anxiety of Children and Their Mothers

Introduction: In comparison with the general population, several studies have reported higher anxiety and depression rates not only in children with allergic diseases but also in their parents. We aimed to evaluate the mental health of children and their mothers affecting quality of life (QoL) in children with allergic diseases, and to compare anxiety and depression in these patients and their parents with the general population.Methods: One hundred and sixty-eight patients aged 8-18 years diagnosed with an allergic disease who visited our outpatient clinic and a control group of 61 children who did not have any chronic or allergic diseases were included in the study. Patients completed the Pediatric QoL Inventory, Trait Anxiety Inventory for Children, and Children's Depression Inventory, while mothers completed the General Anxiety Disorder-7 (GAD-7) scale and the Patient Health Questionnaire-9 (PHQ-9). Independent samples' t-test was used to compare children's QoL, trait anxiety, and depression scores and mothers' GAD-7 and PHQ-9 scores between the controlled/mild and uncontrolled/moderate-severe groups. The effects of age, gender, disease severity, maternal depression/anxiety, and children's depression/anxiety on QoL were analyzed with multivariate regression analyses.Results: QoL was lower in children with allergic diseases than healthy children, and although the mean QoL score was lower in the group with high disease severity, QoL in children with allergic diseases was not associated with disease severity but inversely related to anxiety/depression and maternal depression.Conclusions: As per the results, QoL is impaired in children with allergic diseases. Both anxiety/depression in the child and maternal depression may adversely affect QoL in these patients.

Health-related quality of life in children with and without physical-mental multimorbidity

PURPOSE

This study examined health-related quality of life (HRQL) in children across different physical illnesses; estimated parent-child agreement on HRQL reports; compared HRQL between children with and without physical-mental multimorbidity; and tested if multimorbidity was associated with HRQL.

METHODS

Children aged 6-16 years (mean = 11.1; n = 198) with one physical illness and their parents were recruited from a pediatric hospital. Physical illnesses were classified according to the International Statistical Classification of Diseases and Related Health Problems (ICD)-10, mental illnesses were assessed using the Mini International Neuropsychiatric Interview for Children and Adolescents, and HRQL was measured using the KIDSCREEN-27. Children who screened positive for ≥ 1 mental illness were classified as having physical-mental multimorbidity. χ²/t tests compared sample characteristics of children with vs. without multimorbidity; Kruskal-Wallis tests compared KIDSCREEN-27 scores across ICD-10 categories; interclass correlation coefficients estimated parent-child agreement; and multiple regression examined effects of the number of mental illnesses on HRQL.

RESULTS

HRQL was similar across ICD-10 categories. Parent-child agreement was fair to good for all HRQL domains, regardless of multimorbidity status. Parent-reported HRQL was significantly lower for children with multimorbidity compared to norms across all domains, whereas child-reported HRQL was significantly lower for physical well-being, psychological well-being, and school environment. Number of mental illnesses was negatively associated with psychological well-being and school environment in a dose-response manner.

CONCLUSION

Children with physical-mental multimorbidity are vulnerable to experiencing lower HRQL, particularly for psychological well-being and school environment. Longitudinal studies documenting trajectories of HRQL and school-based interventions that target these domains of HRQL for children with multimorbidity are warranted.

[Coping with life for children with chronic illness: necessary services in the healthcare system]

BACKGROUND

Children and adolescents with chronic diseases are a very heterogeneous group of patients with age-specific characteristics and a broad spectrum of underlying diseases. These patients require not only good medical care but also comprehensive support in order to achieve the greatest possible participation in social life.

OBJECTIVE

In this review, the problems faced by children and adolescents with chronic diseases, as well as by their families, and the requirements for the best possible life management, are presented. The framework conditions of the healthcare system and the necessary supplementary social benefits are presented and necessary steps for further development are discussed.

CONCLUSION

There are numerous services for children and adolescents with chronic diseases, as well as for their families. However due to the often-confusing access paths and a lack of coordination, these services are not seized to the extent necessary. Current efforts to improve coordination of social legislation and developing one-stop services represent a further step towards improving care.

Clinical and lung function outcomes in a cohort of children with severe asthma

BACKGROUND

Uncontrolled severe asthma in children is burdensome and challenging to manage. This study aims to describe outcomes in children with uncontrolled severe asthma managed in a nurse-led severe asthma clinic (SAC).

METHODS

This retrospective analysis uses data collected from children referred by a paediatric respiratory specialist to a nurse-led SAC for uncontrolled severe asthma between 2014 and 2019. The pre-clinical assessments included a home visit to assess modifiable factors that could be addressed to improve control. A comprehensive lung function analysis was conducted at each visit. Interventions were personalised and included biologic agents. Statistical analysis was performed using nonparametric, two-tailed Mann-Whitney U-test, the parametric Student's t-test, or analysis of variance (ANOVA) as appropriate.

RESULTS

Twenty-three children with a median age of 12 years were seen once, and 16 were followed up. Compared to a non-asthmatic (NA) and asthmatic (A) age-matched cohort, children with severe asthma (SA) had a lower FEV1, and FVC% predicted before and after bronchodilator inhalation, and a higher mean Lung Clearance Index [LCI] (10.5 [SA] versus 7.3 [NA] versus 7.6 [A], p = 0.003). Almost 80% of children with SA had an abnormal LCI, and 48% had a reduced FEV1% at the first SAC visit. Asthma control and FEV1% predicted significantly improved at a follow-up visit, while LCI remained abnormal in the majority of children (83%).

CONCLUSION

Over time, many children with severe asthma showed improved clinical outcomes and lung function while lung ventilation inhomogeneities persisted. Future appropriately controlled studies are required to determine if a nurse-led multidisciplinary SAC is associated with better outcomes.

First-year predictors of health-related quality of life changes in short-statured children treated with human growth hormone

PURPOSE

Little attention has been directed towards examining the impact of predictors on change in health-related quality of life (HRQOL) within the course of growth hormone (GH) treatment in pediatric short stature. We aimed to assess changes in HRQOL and its sociodemographic, clinical and psychosocial predictors in children and adolescents diagnosed with growth hormone deficiency (GHD), and born short for gestational age (SGA) before and 12-month after start of GH treatment from the parents' perspective. Results were compared with an untreated group with idiopathic short stature (ISS). In this prospective multicenter study, 152 parents of children/adolescents (aged 4-18 years) provided data on their children's HRQOL at baseline and at 12-month follow-up.

METHOD

Repeated-measures multivariate analyses of covariance were performed to examine parent-reported HRQOL changes from baseline to 1-year after treatment and hierarchical linear regressions to identify the predictors of HRQOL changes.

RESULTS

Results showed that parents of children that were treated with GH report an increase in their children's HRQOL after 1 year. Changes in HRQOL were mostly explained by psychosocial predictors followed by sociodemographic and clinical variables. Specifically, the diagnosis SGA significantly predicted a greater increase in parent-reported HRQOL. Furthermore, a lower caregiving burden significantly predicted a decrease in parent-reported HRQOL.

CONCLUSION

In conclusion, a substantial percentage of explained variance in HRQOL relates to psychosocial and sociodemographic predictors. However, there appears to be other important factors that are predictors of HRQOL, which need to be determined in large, population-based samples.
