Self-efficacy and physical activity in adolescents with trivial, mild, or moderate congenital cardiac malformations

The Child Opportunity Index 2.0 and Disparities in Pediatric Cardiorespiratory Fitness

OBJECTIVE

To evaluate the effect of neighborhood-level characteristics on cardiorespiratory fitness (CRF) via peak oxygen consumption (VO2peak) for healthy pediatric patients.

STUDY DESIGN

The institutional cardiopulmonary exercise testing (CPET) database was analyzed retrospectively. All patients aged ≤ 18 years without a diagnosis of cardiac disease and with a maximal effort CPET were included. Patients were divided into three self-identified racial categories: White, Black, and Latinx. The Child Opportunity Index (COI) 2.0 was used to analyze social determinants of health. CRF was evaluated based on COI quintiles and race. Assessment of the effect of COI on racial disparities in CRF was performed using ANCOVA.

RESULTS

A total of 1753 CPETs met inclusion criteria. The mean VO2peak was 42.1 ± 9.8 mL/kg/min. The VO2peak increased from 39.1 ± 9.6 mL/kg/min for patients in the very low opportunity cohort to 43.9 ± 9.4 mL/kg/min for patients in the very high opportunity cohort. White patients had higher percent predicted VO2peak compared with both Black and Latinx patients (P < .01 for both comparisons). The racial differences in CRF were no longer significant when adjusting for COI.

CONCLUSION

In a large pediatric cohort, COI was associated with CRF. Racial disparities in CRF are reduced when accounting for modifiable risk factors.

Physical Activity Promotion Among Individuals With Tetralogy of Fallot

In the general population, the most cited barriers to physical activity (PA) are time, energy, and motivation. Consequently, despite the significant contribution of PA to health and well-being, many individuals are insufficiently active. Physical inactivity and sedentary lifestyles increase the risk of acquired cardiometabolic disease, a risk that may complicate and is compounded by the anatomic and physiologic features inherent in the patient with repaired tetralogy of Fallot (ToF). Individuals with ToF commonly present with reduced exercise capacity and PA levels. In light of historically PA restrictive management of their heart disease, known reductions in exercise capacity among individuals with ToF are combined with psychosocial barriers to their participation, potentially establishing a cycle of further detraining, inactivity, and disease progression/health decline. To this end, children and young adults with ToF are known to have reduced self-efficacy towards PA, defined as their confidence in their ability to participate. In this review, we apply self-efficacy as an overarching mediator of PA participation and explore trends and determinants of PA participation among individuals with ToF and its subsequent impact on exercise capacity, disease risk, and health-related quality of life. We outline the rationale and strategies aimed at improving PA in children and adults with ToF and highlight current knowledge gaps and future directions in the promotion of PA in the population with ToF.

Exploring the Promise of Telemedicine Exercise Interventions in Children and Adolescents With Congenital Heart Disease

Youth with congenital heart disease (CHD) have reduced exercise capacity via various physical and psychosocial mechanisms. In addition to limited physiologic exercise capacity, these patients experience lower levels of physical activity, physical activity self-efficacy, health-related quality of life, and endothelial function. The study of exercise interventions and cardiac rehabilitation programs in pediatric CHD populations remains limited, particularly home-based interventions that incorporate real-time physiologic monitoring. Home-based interventions provide improved access and convenience to patients. This is principally important for patients from geographically disperse regions who receive their care at centralized subspecialty centres, as is the case for Canadian pediatric cardiac care. These programs, however, have traditionally not permitted the supervision of safety, technique, and adherence that are afforded by hospital/facility-based programs. As such, telemedicine is an important evolving area that combines the benefits of traditional home and facility-based cardiac rehabilitation. An additional key area lacking study surrounds the types of exercise interventions in youth with CHD. To date, interventions have often centred around moderate-intensity continuous exercise. High-intensity interval training might offer superior cardiorespiratory advantages but remains understudied in the CHD population. In this review, we highlight the existing evidence basis for exercise interventions in youth with CHD, explore the promise of incorporating telemedicine home-based solutions, and highlight key knowledge gaps. To address identified knowledge gaps, we are undertaking a 12-week randomized crossover trial of a home-based telemedicine high-intensity interval training intervention in youth with repaired moderate-severe CHD using a video game-linked cycle ergometer (known as the MedBIKE; https://spaces.facsci.ualberta.ca/ahci/projects/medical-projects/remote-rehab-bike-projects).

Preventing sedentary lifestyles among young children born with congenital heart defects: A feasibility study of physical activity rehabilitation after surgical or catheterization intervention

BACKGROUND

Children with congenital heart disease (CHD) often have inactive lifestyles and motor skill deficits beginning in infancy. The least active infants continue to be the least active children at school age. Enhancing physical activity and motor development in infancy, at the time of CHD treatment, may prevent inactive lifestyle habits.

METHODS

All children being treated, through surgery or catheterization, for congenital heart disease are eligible if they are 3 to 72 months of age at enrollment. The Peabody Motor Development Scales (Version 2) and 7-day accelerometry (Actigraph GT9X Link) assess motor skills and physical activity prior to treatment and 7 weeks, 6 months and 12 months post-treatment. Participants are randomized 3:1 to intervention:control. Until 7 weeks post-treatment, intervention activities focus on regaining pre-treatment mobility and midline crossing. From 7 weeks to 6 months post-treatment, the intervention is individualized to each child's assessment results and is parent-led, delivered at home and play-based.

CONCLUSION

This feasibility study will provide essential data for a randomized controlled trial to evaluate play-based, parent-delivered interventions optimized to support age-appropriate physical activity and motor skills among young children with CHD. Preliminary intervention efficacy data will inform an evidence-based sample size calculation, optimize intervention timing, and identify hypotheses on the motor skill-physical activity connection and the impact of play-based, parent-led interventions during recovery from CHD treatment. Long-term, the goal is to optimize motor skill and active lifestyles among young children with CHD, enabling their healthy growth and development and enhancing childhood quality of life.

Evaluating a Telemedicine Video Game-Linked High-Intensity Interval Training Exercise Programme in Paediatric Heart Transplant Recipients

Paediatric heart transplant recipients (HTRs) have reduced exercise capacity, physical activity (PA), health-related quality of life (HRQoL), and self-efficacy towards PA. Exercise interventions have demonstrated improvements in exercise capacity and functional status in adult HTRs, with a specific emerging interest in the role of high-intensity interval training (HIIT). Studies of exercise interventions in paediatric HTRs have been limited and nonrandomized to date. HIIT has not yet been evaluated in paediatric HTRs. We thus seek to evaluate the safety and feasibility of a randomized crossover trial of a 12-week, home-based, video game-linked HIIT intervention using a cycle ergometer with telemedicine and remote physiological monitoring capabilities (MedBIKE) in paediatric HTRs. The secondary objective is to evaluate the impact of the intervention on (1) exercise capacity, (2) PA, (3) HRQoL and self-efficacy towards PA, and (4) sustained changes in secondary outcomes at 6 and 12 months after intervention. After a baseline assessment of the secondary outcomes, participants will be randomized to receive the MedBIKE intervention (12 weeks, 36 sessions) or usual care. After the intervention and a repeated assessment, all participants will cross over. Follow-up assessments will be administered at 6 and 12 months after the MedBIKE intervention. We anticipate that the MedBIKE intervention will be feasible and safely yield sustained improvements in exercise capacity, PA, HRQoL, and self-efficacy towards PA in paediatric HTRs. This study will serve as the foundation for a larger, multicentre randomized crossover trial and will help inform exercise rehabilitation programmes for paediatric HTRs.

Positive mindset and exercise capacity in school-aged children and adolescents with congenital heart disease

Introduction

Patients with congenital heart disease (CHD) have variable degrees of peak oxygen consumption (VO₂) that can be improved with supervised fitness training. The ability to exercise is affected by anatomy, hemodynamics, and motivation. Motivation is in part related to mindset, or personal attitudes and beliefs, and a more positive mindset around exercise has been associated with better outcomes. It is unknown whether variations in measured peak VO₂ in patients with CHD are related to having a positive mindset.

Methods

Patient's ages 8-17 years with CHD were administered quality of life and physical activity questionnaires at the time of their routine cardiopulmonary exercise test. Those with severe hemodynamic burden were excluded. Patients were grouped based on disease classification. Mindset was evaluated via validated questionnaires including a PROMIS Meaning and Purpose (MaP) survey and an Anxiety survey. Pearson correlation coefficients were calculated to estimate the magnitude of the association between percent predicted peak oxygen consumption (pppVO₂) and questionnaire scores overall and within CHD subgroups.

Results

Eighty-five patients participated; median age was 14.7 years, 53% were female, 66% had complex CHD, 20% had simple CHD, and 14% had single ventricle heart disease. Mean MaP scores were significantly lower in all CHD groups compared to population norms (p < 0.001). As a group, MaP scores were positively associated with the amount of reported physical activity (p = 0.017). In patients with simple CHD, MaP scores were positively associated with pppVO₂ (p = 0.015). The association was even stronger for MaP:Anxiety, with worse ratios associated with lower pppVO₂ (p = 0.005). Patients with complex and single ventricle CHD did not show a similar association.

Conclusions

Patients with CHD, regardless of severity, had lower meaning and purpose scores than the general population, and these scores were associated with amount of reported physical activity. In the simple CHD subset, having a more positive mindset was associated with higher peak VO₂ and a more negative mindset with lower peak VO₂. This relationship was not seen with more significant CHD. While underlying CHD diagnoses are not modifiable, mindset and peak VO₂ are, and consideration should be given to measuring both as each may be a target for intervention.

Life satisfaction, health-related quality of life and physical activity after treatment for valvular aortic stenosis

OBJECTIVE

To investigate health-related quality of life and life satisfaction in children and adolescents treated for isolated congenital valvular aortic stenosis compared to healthy peers. Our second aim was to investigate the relationship between objectively measured physical activity, health-related quality of life and life satisfaction in the same group.

METHODS

Forty-eight patients, 8-18 years of age, were recruited, as well as 43 healthy peers matched for age, gender and residential area. Health-related quality of life was assessed by the KIDSCREEN-52 self-report and parent proxy report, and life satisfaction was evaluated with the Satisfaction With Life Scale. Physical activity was measured with an accelerometer for 7 days. Sports participation was self-reported.

RESULTS

No differences in the health-related quality of life domains were found between patients and controls in the self-reports. In the proxy reports, parents of the adolescents rated their child's autonomy lower than did the parents of the healthy controls. A negative relationship was found between moderate to vigorous physical activity, sports participation, life satisfaction and the psychological well-being domain in adolescent patients. In children there was a positive relationship between moderate physical activity and the physical and psychological well-being domains.

CONCLUSION

Overall, children and adolescents treated for valvular aortic stenosis reported similar life satisfaction and health-related quality of life as their healthy peers. The negative relationships between intense physical activity and sports participation with health-related quality of life and life satisfaction in adolescent patients might be explained by both physical and psychological factors in these teenagers with complex, lifelong heart disease.

Participation in physical activity of adolescents with congenital heart disease

BACKGROUND

Participation in physical activity improves health in individuals with congenital heart disease. However, most do not sufficiently engage in physical activity. The aim of this study was to collect information regarding the experiences of adolescents with congenital heart disease who practiced physical activities.

METHODS

French adolescents aged 13-18 years, diagnosed with congenital heart disease, class I or II dyspnoea on the NYHA scale and authorized physical activity were interviewed individually about their physical activity experiences using a semi-structured format. The qualitative interview transcript data were analysed using a phenomenological approach; data analysis was performed independently by three researchers and merged at each step until saturation.

RESULTS

Eleven adolescents with congenital heart disease participated. Three main themes emerged: 'own representation', 'physical activity (PA) set-up' and 'environment'. Adolescents had a generally positive view of physical activity, which was associated with positive experiences. However, they reported that their physical condition limited PA, and they wished for adapted activities. The results revealed the importance of environmental factors, for example, within the social and school environments. The participants indicated that they appreciated the social interactions that PA afforded, but that integration into a group could be difficult, especially in school, with some participants describing feelings such as anxiety, frustration or guilt when they could not participate fully. PA facilitators included familial support. However, participants noted a lack of clear medical guidance to help them choose suitable activities based on their circumstances and personal preferences. They wished for the public to be better informed about congenital heart disease to reduce stigmatism.

CONCLUSIONS

This study provides valuable information for clinicians, physical educators and policy makers to help them promote physical activity and support adolescents and their families in understanding their own condition, maximizing their potential and in their choice of activities.

Safety and efficacy of exercise training in children and adolescents with congenital heart disease: A systematic review and descriptive analysis

BACKGROUND

While exercise training is beneficial in the prevention and management of many chronic diseases, the role of exercise training in children and adolescents with congenital heart disease is less understood. We sought to determine the safety and efficacy of exercise training in children and adolescents with congenital heart disease.

METHODS

We conducted a systematic search of the following databases: PubMed, CINAHL, EMBASE, Web of Science and SportDiscus. We included randomised controlled trials that incorporated an exercise intervention compared with a non-exercising comparator group and examined safety and efficacy in children and adolescents with congenital heart disease. A descriptive analysis of the included trials was then conducted.

RESULTS

A total of 9 articles from 6 trials (642 participants with varying conditions and disease severity) were included. Significant variability of study participants and outcomes were observed across the trials. No adverse events linked to the exercise interventions were stated. The articles reported numerous positive changes to clinically relevant fitness measures. Exercise capacity improved with exercise training in 3 of 4 trials in which it was measured. Cardiorespiratory fitness showed improvements in 3 of 4 trials. Neuromuscular fitness increased in 1 of 2 trials. Physiological and metabolic parameters were improved, and negative changes were not observed to several clinically important measures (e.g. muscular oxygenation, cardiac measures) in 2 of 2 trials. Physical activity increased in 1 of 3 trials. No articles reported on changes in measures of body composition. Outcomes are varied with little consensus on measurements or assessment methods.

CONCLUSIONS

Exercise training appears to be safe and efficacious for improving physical fitness in children and adolescents with congenital heart disease who have been appropriately screened by their medical team. However, the certainty of the evidence for these findings is low to moderate.

Promoting positive physical activity behaviors for children and adolescents undergoing acute cancer treatment: Development of the CanMOVE intervention using the Behavior Change Wheel

Background

Increasing participation in physical activity has the potential to improve outcomes for children and adolescents with cancer during treatment and into survivorship. The aim of this study is to outline the theoretical process behind development of CanMOVE, a behavior change intervention designed to increase physical activity for children and adolescents with cancer.

Study design

This study followed a theoretical design process consistent with the Behavior Change Wheel to inform the design of a complex intervention.

Materials and methods

The three stages of the Behavior Change Wheel intervention design process include: (1) understanding physical activity behavior within the pediatric cancer setting, (2) identifying potential intervention functions, and (3) identifying appropriate behavior change and implementation strategies. Qualitative and behavior change literature relevant to the pediatric cancer treatment setting were used to inform each stage.

Results

An individualized and flexible approach to physical activity promotion that considers intrinsic factors specific to the child/adolescent and their environment is required. Fifteen behavioral change strategies were identified to form the intervention components of CanMOVE. Implementation strategies were identified to build motivation, opportunity and capacity toward increasing physical activity behaviors. Key intervention components of CanMOVE include standardized assessment and monitoring (physical activity, physical function, and health-related quality of life), provision of an activity monitor to both child/adolescent and parent, and one-on-one capacity building sessions with a healthcare professional. Capacity building sessions include education, goal setting, an active supervised physical activity session, barrier identification and problem solving, and action planning.

Conclusion

CanMOVE is a novel approach to physical activity promotion in the pediatric cancer treatment setting. The use of a theoretical intervention design process will aid evaluation and replication of CanMOVE when it is assessed for feasibility in a clinical setting. The design process utilized here can be used as a guide for future intervention development.

Physical Activity in Fontan Patients Relates to Quality of Life and Sleep Quality

Background and Aim

Fontan patients tend to have reduced physical exercise capacity. This study investigates physical activity (PA) and its relationship to exercise capacity, heart rates, cardiac function, biomarkers, health-related quality of life (HRQoL), and sleep quality.

Methods

Cardiovascular magnetic resonance (CMR), exercise testing (CPET), 24 h-ECG, and blood samples were prospectively performed in 38 patients, age 13 (11–16) years. PA was assessed by accelerometer during 7 consecutive days. HRQoL was self-assessed with KIDSCREEN-27 and SF-36 according to patients' age; sleep quality with Pediatric Sleep Questionnaire (PSQ) and Pittsburgh Sleep Quality Index (PSQI).

Results

Daily moderate to vigorous physical activity (MVPA) was in median (IQR) 40 (28–57) mins; 7/38 (18%) patients reached the recommended 60 mins/day of MVPA. MVPA did not correlate with gender, age, single ventricle morphology, time from Fontan, heart rate, ventricular volumes, and ejection fraction at CMR, biomarkers, or CPET. Physical wellbeing (r = 0.33, p = 0.04), autonomy (r = 0.39, p = 0.03), and social support (r = 0.43, p = 0.009) assessed using the KIDSCREEN-27, and both physical (r = 0.57, p = 0.03) and mental (r = 0.54, p = 0.04) domains of the SF-36 questionnaire correlated with daily minutes of MVPA. PSQI global sleeping score (r = −0.7, p = 0.007), and PSQ scales for behavior (r = −0.36; p = 0.03) correlated with daily minutes of MVPA.

Conclusion

Only 18% of the Fontan patients meet the recommendation for daily MVPA. Measures of exercise capacity, cardiac function or chronotropic competence are not correlated to daily physical activity. In contrast, HRQoL and sleep quality seem to be associated with regular physical activity.

Differences between Sexes in Cardiopulmonary Fitness among Children and Adolescents with Kawasaki Disease

It is known that children and adolescents with Kawasaki disease (KD) can maintain normal cardiopulmonary fitness (CPF) after the disease’s acute stage has subsided. This study aimed to investigate whether gender differences affect CPF in children and adolescents with KD. We retrospectively reviewed a cohort of 204 participants (120 boys and 84 girls) with KD. All participants were instructed to complete a symptom-limited cardiopulmonary exercise test (CPET) adapted to assess their CPF. Based on body mass index (BMI), boys and girls were categorized into groups of underweight (19 boys and 12 girls), normal (62 boys and 59 girls), and overweight (39 boys and 13 girls). Although a similarity in body composition was found among both genders for KD subjects and normal Taiwanese peers, the percentage of overweight subjects was higher in KD boys than the normal Taiwanese boys. When comparing CPF for different BMI groups, the whole KD group showed no discrepancy, but a significantly lower peak VO2 for the overweight KD boys group was observed, representing poorer CPF. In conclusion, girls with KD had better CPF than boys, and gender stereotypes affect sports participation as well as self-efficacy, and may be contributing to poorer CPF in KD boys.

Differences in Cardiopulmonary Fitness Between Boy and Girls With Repaired Tetralogy of Fallot

OBJECTIVE

Many studies have demonstrated that patients with repaired tetralogy of Fallot (rTOF) have generally poorer cardiopulmonary fitness (CPF). However, little is known about how the disease results in different CPF in each sex. Therefore, this study aimed to investigate whether sex (and gender) differences affect CPF in children and adolescents with rTOF.

METHODS

This retrospective study recruited adolescents and children (aged 10-18) with rTOF following an acute stage of tetralogy of Fallot (TOF) who received cardiopulmonary exercise testing (CPET) in the past 10 years. CPF was determined by symptom-limited CPET with a treadmill under ramped Bruce protocol. Boys and girls were categorized into groups based on body mass index (BMI) and fat mass index (FMI). The BMI was grouped by Taiwanese obesity cutoff points. The FMI was categorized by the body fat percentage. Excess adiposity was defined as (1) "overweight" and "obese" by BMI and (2) greater than the sex- and age-specific 75th percentile of whole subjects by FMI.

RESULTS

A total of 185 participants (104 boys and 81 girls) with rTOF were recruited for the final analysis. Within the BMI category, 76 boys and 63 girls were in the normal group, whereas 28 boys and 18 girls were in the excessive adiposity group. Within the FMI category, 77 boys and 60 girls were in the normal group, whereas 27 boys and 21 girls were in the excessive adiposity group. The analysis of the body composition of rTOF subjects showed that there was no statistically significant difference between the subgroups of the two sexes, but both showed a smaller body size than normal Taiwanese children. When comparing the CPF within different BMI and FMI groups, the children in the excessive adiposity group had significantly lower values in metabolic equivalents (MET) at anaerobic threshold, peak MET, and measured peak oxygen consumption (VO₂) to predicted peak VO₂, regardless of sex. Moreover, boys (60.90%) presented poorer CPF than girls (74.22%, p < 0.001).

CONCLUSION

In Taiwan, patients with rTOF had poorer CPF than healthy peers. This study found that girls with rTOF had better CPF than boys with rTOF. The effect of gender stereotypes on sports participation and self-efficacy might be one of the contributing factors; however, further investigations are warranted to determine the causal effect.

Exercise prescription improves exercise tolerance in young children with CHD: a randomised clinical trial

Objective

The main objective of this study was to ascertain if a structured intervention programme can improve the biophysical health of young children with congenital heart disease (CHD). The primary end point was an increase in measureable physical activity levels following the intervention.

Methods

Patients aged 5–10 years with CHD were identified and invited to participate. Participants completed a baseline biophysical assessment, including a formal exercise stress test and daily activity monitoring using an accelerometer. Following randomisation, the intervention group attended a 1 day education session and received an individual written exercise plan to be continued over the 4-month intervention period. The control group continued with their usual level of care. After 4 months, all participants were reassessed in the same manner as at baseline.

Results

One hundred and sixty-three participants (mean age 8.4 years) were recruited, 100 of whom were male (61.3%). At baseline, the majority of the children were active with good exercise tolerance. The cyanotic palliated subgroup participants, however, were found to have lower levels of daily activity and significantly limited peak exercise performance compared with the other subgroups. One hundred and fifty-two participants (93.2%) attended for reassessment. Following the intervention, there was a significant improvement in peak exercise capacity in the intervention group. There was also a trend towards increased daily activity levels.

Conclusion

Overall physical activity levels are well preserved in the majority of young children with CHD. A structured intervention programme significantly increased peak exercise capacity and improved attitudes towards positive lifestyle changes.

Physical activity modification in youth with congenital heart disease: a comprehensive narrative review

Congenital heart disease (CHD) affects nearly 1% of births. As survival rates have dramatically improved, the majority of individuals with CHD now live into adulthood. As these patients age, they become prone to a large range of complications, such as chronic heart failure and acquired cardiovascular disease. Promotion of a healthy and active lifestyle from childhood onwards has been suggested as a sustainable and effective strategy to enhance cardiovascular health, improve quality of life and reduce immediate and long-term risk in people with CHD. Well-established physical activity consensus statements for youth with CHD have now been published. In this article, we review how increasing physical activity in youth with CHD may offer immediate and long-term cardiovascular benefits, what is known about physical activity in children with CHD, describe the unique factors that contribute to achieving sufficient and insufficient physical activity levels and summarize the evidence of trials on physical activity promotion in youth with CHD. Furthermore, we discuss some of the challenges that need to be addressed by further research regarding the optimal strategy, timing and format of physical activity intervention programmes in children and adolescents with CHD. IMPACT: Congenital heart disease (CHD) affects nearly 1% of births, with the majority of individuals with CHD now living into adulthood due to improved survival. As CHD patients age, they become prone to a large range of cardiovascular complications. This article discusses how and why increasing physical activity in youth with CHD may offer immediate and long-term cardiovascular benefits, the barriers to achieving sufficient physical activity levels and the evidence from trials on physical activity promotion in youth with CHD. The optimal strategy, timing and format of physical activity intervention programmes in children and adolescents with CHD are discussed.

Developing patient resources to enable the exchange of healthy lifestyle information between clinicians and families of children with complex heart problems

BACKGROUND

Healthy active lifestyles are critically important for children with complex heart problems (CHP) that affect heart structure, rhythm or function. They are at increased risk for morbidities such as atherosclerosis, obesity, anxiety and depression. Educating children with CHP and their families about the relevance of healthy lifestyles is an important part of clinical care.

DESIGN

This study used a collaborative approach among six patients/family members and 22 health professionals to develop a series of knowledge-to-action tools suitable for counselling children with CHP and their families about their healthy lifestyle needs.

METHODS

After development of the knowledge-to-action tools had been completed, one cardiologist and one research assistant implemented one or more of these new resources during each clinic visit as appropriate for each patient. Thirty-nine parents and eight children completed post-clinic interviews to explore their perceptions of the new resources. The nine resources developed included brochures and websites addressing physical activity with a heart condition, body contact restrictions, exercise test results, emotional health, finding community resources, encouragement for asking healthy lifestyle questions and a brief, in-clinic healthy lifestyle assessment.

RESULTS

Families found the resources useful and helpful for clarifying their specific concerns. They also provided suggestions to improve the content and delivery of the resources so that they would be suitable for a variety of settings-schools, community and sports.

CONCLUSION

Future research is required to evaluate the effectiveness of these resources for raising awareness and knowledge about healthy active lifestyles among children with CHP and the impact of these resources for changing healthy lifestyle behaviours.

Physical activity in children and adolescents with CHD: review from a measurement methodological perspective

AIM

To compile a literature overview of physical activity in children with CHD and to critically evaluate the methodology used for physical activity assessment.

METHODS

A review of the literature was performed using PubMed to identify studies examining accelerometer and subjectively assessed physical activity in children and adolescents with CHD.

RESULT

A total of 15 studies were included (6 studies using subjective measures and 9 articles using accelerometers for the assessment of physical activity). The patients generally failed to meet the recommendations of physical activity. When compared to healthy controls, the results were widely divergent in the subjectively assessed measures and the accelerometer-based studies showed a tendency of no difference in physical activity. Neither subjective methods nor accelerometer-based studies reported any difference in physical activity in general, in relation to the severity of the heart disease.

CONCLUSION

Methodological variation and limitations in the assessment of physical activity largely explain the divergent results and the inability to establish differences in physical activity between children with CHD of different severity and compared to healthy controls. Methodological knowledge and guidelines are provided for improved assessment of physical activity using accelerometers in clinical research.

Children and Adolescents Treated for Valvular Aortic Stenosis Have Different Physical Activity Patterns Compared to Healthy Controls: A Methodological Study in a National Cohort

Previous research in children and adolescents with congenital heart defects presents contradictory findings concerning their physical activity (PA) level, due to methodological limitations in the PA assessment. The aim of the present cross-sectional study was to compare PA in children and adolescents treated for valvular aortic stenosis with healthy controls using an improved accelerometer method. Seven-day accelerometer data were collected from the hip in a national Swedish sample of 46 patients 6-18 years old treated for valvular aortic stenosis and 44 healthy controls matched for age, gender, geography, and measurement period. Sports participation was self-reported. Accelerometer data were processed with the new improved Frequency Extended Method and with the traditional ActiGraph method for comparison. A high-resolution PA intensity spectrum was investigated as well as traditional crude PA intensity categories. Children treated for aortic stenosis had a pattern of less PA in the highest intensity spectra and had more sedentary time, while the adolescent patients tended to be less physically active in higher intensities overall and with less sedentary time, compared to the controls. These patterns were evident using the Frequency Extended Method with the detailed PA intensity spectrum, but not to the same degree using the ActiGraph method and traditional crude PA intensity categories. Patients reported less sports participation than their controls in both age-groups. Specific differences in PA patterns were revealed using the Frequency Extended Method with the high-resolution PA intensity spectrum in Swedish children and adolescents treated for valvular aortic stenosis.

Perceptions of Healthy Lifestyles Among Children With Complex Heart Disease and Their Caregivers

Background

Children with complex heart problems may be at higher risk for sedentary lifestyle morbidities than their healthy peers. This project examined perceptions, barriers, and supports that influence healthy active lifestyles among children with complex heart problems and their caregivers, to enable effective health and quality-of-life interventions.

Methods

Inductive thematic analysis was conducted of semi-structured guided discussions from 6 focus groups (young child [n = 2]; older child [n = 4]; parents of young child [n = 4]; parents of older child [n = 4]; pediatric cardiologist [n = 5]; pediatric cardiac nurse [n = 5]) and individual interviews with 7 parents, 5 parent/child dyads, 2 adults with complex heart problems, 6 pediatric cardiologists, 3 pediatric cardiac nurses, 4 pediatric cardiology mental health professionals, and 14 recreation professionals.

Results

Four interrelated themes were identified: (i) "It takes a village"—coordinated and collaborative interdisciplinary support; (ii) clear healthy lifestyle communication among children, families, and professionals is critically important; (iii) Ccreating supportive environments by building professional expertise; (iv) inspiring healthy lifestyles in the children’s own environments. All groups identified a need to improve knowledge about childhood heart conditions among education and recreation professionals and to encourage effective communication between healthcare professionals and families. Participants indicated that these changes would support families, educators, and recreation professionals in engaging children with heart problems in healthy lifestyles in home, school, and community settings.

Conclusions

Important healthy lifestyle barriers were identified within individuals and in their interactions. There is a profound need to enhance knowledge of childhood heart conditions and improve interactions among key stakeholders—children and families, educators, and recreation and healthcare professionals.

Mismatch between self-estimated and objectively assessed exercise capacity in patients with congenital heart disease varies in regard to complexity of cardiac defects

AIM

Regular evaluation of physical capacity takes a crucial part in long-term follow-up in patients with congenital heart disease (CHD). This study aims to examine the accuracy of self-estimated exercise capacity compared to objective assessments by cardiopulmonary exercise testing in patients with CHD of various complexity.

METHODS

We conducted a single centre, cross-sectional study with retrospective analysis on 382 patients aged 8-68 years with various CHD who completed cardiopulmonary exercise tests. Peak oxygen uptake was measured. Additionally, questionnaires covering self-estimation of exercise capacity were completed. Peak oxygen uptake was compared to patient's self-estimated exercise capacity with focus on differences between complex and non-complex defects.

RESULTS

Peak oxygen uptake was 25.5 ± 7.9 ml/minute/kg, corresponding to 75.1 ± 18.8% of age- and sex-specific reference values. Higher values of peak oxygen uptake were seen in patients with higher subjective rating of exercise capacity. However, oxygen uptake in patients rating their exercise capacity as good (mean oxygen uptake 78.5 ± 1.6%) or very good (mean oxygen uptake 84.8 ± 4.8%) was on average still reduced compared to normal. In patients with non-complex cardiac defects, we saw a significant correlation between peak oxygen uptake and self-estimated exercise capacity (spearman-rho -0.30, p < 0.001), whereas in patients with complex cardiac defects, no correlation was found (spearman-rho -0.11, p < 0.255).

CONCLUSION

The mismatch between self-estimated and objectively assessed exercise capacity is most prominent in patients with complex CHD.Registration number at Charité Universitätsmedizin Berlin Ethics Committee: EA2/106/14.

Physical activity assessments in children with congenital heart disease: A systematic review

AIM

To describe the physical activity (PA) of children with congenital heart disease (CHD) according to different assessment methods and compare their results with the World Health Organization (WHO) recommendations.

METHODS

A systematic review was conducted using five databases. We included cross-sectional, longitudinal, observational studies and clinical trials in a paediatric population with CHD. In publications with indirect measurement, the score in each dimension was considered. Similarly, moderate-to-vigorous PA (MVPA) was considered as the main outcome in articles with direct measurement.

RESULTS

A total of 1103 articles were found, and 16 primary articles were considered. Eight articles evaluated PA with indirect methods, six with direct methods and two used both methods, representing 1649 subjects evaluated. It was found that 46% of children with CHD do not exceed WHO recommendations for MVPA, with no differences depending on the severity of CHD.

CONCLUSION

There are a variety of ways to measure PA in children with CHD. In the articles that objectively evaluated PA, the most measured outcome was the MVPA, which shows that the MVPA time was shorter in about half of the children with CHD than what is recommended by WHO.

Physical Activity Patterns in Children and Adolescents With Heart Disease

PURPOSE

To quantify the differences in daily physical activity (PA) patterns, intensity-specific volumes, and PA bouts in youth with and without heart disease (HD).

METHODS

Seven-day PA was measured on children/adolescents with HD (n = 34; median age 12.4 y; 61.8% male; 70.6% single ventricle, 17.7% heart failure, and 11.8% pulmonary hypertension) and controls without HD (n = 22; median age 12.3 y; 59.1% male). Mean counts per minute were classified as sedentary, light, and moderate to vigorous PA (MVPA), and bouts of MVPA were calculated. PA was calculated separately for each hour of wear time from 8:00 to 22:00. Multilevel linear mixed modeling compared the outcomes, stratifying by group, time of day, and day part (presented as median percentage of valid wear time [interquartile range]).

RESULTS

Compared with the controls, the HD group had more light PA (33.9% [15%] vs 29.6% [9.5%]), less MVPA (1.7% [2.5%] vs 3.2% [3.3%]), and more sporadic bouts (97.4% [5.7%] vs 89.9% [9.2%]), but fewer short (2.0% [3.9%] vs 7.1% [5.7%]) and medium-to-long bouts (0.0% [1.9%] vs 1.6% [4.6%]) of MVPA. The HD group was less active in the late afternoon, between 15:00 and 17:00 (P < .03). There were no differences between groups in sedentary time.

CONCLUSION

Children/adolescents with HD exhibit differences in intensity-specific volumes, PA bouts, and daily PA patterns compared with controls.

Participation in leisure activities in adolescents with congenital heart defects

AIM

To describe leisure participation in adolescents with congenital heart defects (CHD) and identify factors associated with intensity of participation.

METHOD

Eighty adolescents with CHD were recruited (39 males, 41 females; mean age [SD] 15y 8mo [1y 8mo] range 11y 5mo-19y 11mo) of whom 78 completed the Children's Assessment of Participation and Enjoyment (CAPE) outcome measure of leisure participation. The measure has five subscales: recreational, active-physical, social, skill-based, and self-improvement. Associations between the CAPE and age, sex, and development were examined. Motor ability (Movement Assessment Battery for Children, Second Edition), cognition (Leiter International Performance Scale-Revised), behavior (Strengths and Difficulties Questionnaire), and motivation (Dimensions of Mastery Questionnaire) were assessed.

RESULTS

Participants exhibited impaired motor (43.5%), behavioral (23.7%), and cognitive (29.9%) development. The most intense participation was in social (mean [SD] 3.3 [0.99]) and recreational (2.9 [0.80]) activity types on the CAPE. Male sex (p<0.05) and younger age were associated with greater physical activity (<15y: 1.87; ≥15y: 1.31, p<0.05). Greater engagement in social activities was related to better cognition (r=0.28, p<0.05), higher motor function (r=0.30-0.36, p<0.01), and fewer behavioral difficulties (r=-0.32 to -0.47, p<0.01). Cognitive ability (r=0.27, p<0.05), dexterity and aiming/catching (r=0.27-0.33, p<0.05), and behavior problems (r=0.38-0.49, p=0.001) were correlated with physical activity participation. Persistence in tasks, an aspect of motivation, correlated with physical (r=0.45, p<0.001) and social activity involvement (r=0.28, p<0.05).

INTERPRETATION

Ongoing developmental impairments in adolescents with CHD are associated with decreased active-physical and social engagement, putting them at risk of poor physical and mental health. Health promotion strategies should be considered.

WHAT THIS PAPER ADDS

Adolescents with congenital heart defects (CHD) have limited engagement in active-physical leisure activities. Cognitive, motor, and behavioral impairments are associated with decreased participation in leisure in children with CHD. Female sex and older age are associated with less engagement in leisure. Mastery motivation correlates with participation, suggesting an avenue for intervention.

"I really like playing games together": Understanding what influences children with congenital heart disease to participate in physical activity

BACKGROUND

Participation in physical activity is essential to the long-term health and development of all children. However, children living with cardiac conditions are typically not active enough to sustain positive health outcomes. Understanding the experiences of children living with congenital heart disease in community-based settings could help inform the physical activity counselling practices of clinicians. The current study explored the perceptions of 7- to 10-year-old children with moderate or complex congenital heart disease as they participated in a 10-week multisport programme.

METHODS

Detailed field notes recorded the discussions and behaviours of 11 participants (45% female participants) each week during the programme sessions. Among those, four participants (50% female participants) were purposively selected to participate in preprogramme and postprogramme focus groups to gather more detailed accounts of their experiences.

RESULTS

Four main themes surrounding physical activity were identified: (a) motivation, (b) self-efficacy, (c) peer influences, and (d) family influences. Although feelings of excitement and enjoyment towards physical activity were prevalent throughout the data ("I'm really excited … because I really like those sports"), participants also often felt frustrated, nervous, and fatigued ("I'm not very good at the skills"). Social inclusion with peers and family influences were meaningful reasons to engage in physical activity ("I really like playing games together"). Following the completion of the programme, participants emphasized their enjoyment of physical activity as a primary source of motivation, demonstrating an important shift from recognizing positive health outcomes ( "… it's good for you") towards more intrinsic sources of motivation ("… because it's fun").

CONCLUSION

Opportunities for physical activity that enhance positive experiences and build intrinsic motivation should be identified and promoted to children with congenital heart disease. Community-based programmes may also be an appropriate context for children with cardiac conditions to engage and maintain participation in physical activity through adolescence.

Physical activity for children undergoing acute cancer treatment: A qualitative study of parental perspectives

BACKGROUND

Little is known about how to facilitate participation in physical activity among children receiving acute cancer treatment.

OBJECTIVE

To understand the parental perspectives on physical activity for children during acute cancer treatment and explore strategies to overcome physical inactivity.

METHODS

A qualitative study was completed. Data were collected via semistructured interviews with parents of children (aged 4-18 years) who were in their first nine months of cancer treatment. Data were analyzed thematically.

RESULTS

Twenty parents were interviewed. A childhood cancer diagnosis and subsequent treatment were described as setting in motion a spiral of physical inactivity. Parents identified movement restrictions as a result of commencing treatment and the hospital environment as factors initiating this decline. Parents described the subsequent impact of movement restrictions on their child over time including loss of independence, isolation, and low motivation. These three consequences further contributed to an inability and unwillingness to be physically active. Parents responded in a variety of ways to their child's inactivity, and many were motivated to overcome the barriers to physical activity yet exhibited a reduced capacity to do so. Suggested intervention strategies highlighted the need for comprehensive support from the organization providing treatment.

CONCLUSIONS

Reasons for reduced physical activity in children receiving acute treatment for cancer are complex and multifactorial. Inactivity cannot be addressed by children and parents alone but requires support from the oncology team through changes to the environment, services, and policies to promote physical activity. These findings may be used to inform targeted, effective, and feasible physical activity interventions.

Parenting stress mediates the association between cyanotic congenital heart disease and internalising problems in children and adolescents

BACKGROUND

Children and adolescents with cyanotic congenital heart disease have been found to be at an increased risk of internalising problems. The underlying mechanisms, however, remain uncertain.

AIMS

To examine the association between cyanotic congenital heart disease and internalising problems and assess whether parenting stress mediates this association.

METHOD

The study sample was 699 children and adolescents (aged 2-17 years) with congenital heart disease (253 with cyanotic congenital heart disease and 446 with acyanotic congenital heart disease) in Taiwan. The Child Behavior Checklist and the Parenting Stress Index were used to assess internalising problems and parenting stress, respectively. A series of multiple regression models was conducted using the SPSS PROCESS procedure to test the association between types of congenital heart disease and internalising problems and the mediating role of parenting stress. A bootstrapping approach was applied to determine the significance of mediation.

RESULTS

Compared with acyanotic congenital heart disease, cyanotic congenital heart disease was associated with increased levels of internalising problems (B=2.52, P<0.01), and this association was mediated by parenting stress (B=0.97, 95% bias-corrected bootstrap confidence interval 0.24, 1.75). In particular, parents of children with cyanotic congenital heart disease reported significantly more parenting stress compared with parents of children with acyanotic congenital heart disease (B=4.63, P<0.01), which contributed to elevated levels of internalising problems in the offspring (B=0.21, P<0.001).

CONCLUSION

Cyanotic congenital heart disease conferred risks for internalising problems in children and adolescents, and this association was mediated by parenting stress. Interventions to decrease internalising problems in children and adolescents with cyanotic congenital heart disease may be more effective by targeting parenting stress.

Factors Influencing Physical Activity in Adolescents with Complex Congenital Heart Disease

Purpose

We aimed to identify factors influencing physical activity in adolescents with complex congenital heart disease.

Methods

We recruited 92 adolescents with complex congenital heart disease from a tertiary medical center in Seoul, measured their levels of physical activity, and identified factors that influenced their physical activity levels using the Global Physical Activity Questionnaire, the New York Heart Association classification, congenital heart disease complexity, the Self-Efficacy Scale, and the Parental Bonding Instrument scale. Stepwise multiple linear regression was used to determine factors influencing physical activity.

Results

Total physical activity was higher in males than in females (t=4.46, p<.001). Adolescents who participated in school physical education classes engaged in more physical activity than those who did not (t=6.77, p<.001). Higher self-efficacy (β=.41, p<.001), male gender (β=.37, p<.001) and participation in school physical education classes (β=.19, p=.042) were associated with a higher likelihood of engagement in physical activity.

Conclusion

It is necessary to develop nursing interventions that enhance self-efficacy in order to promote physical activity in adolescents with complex congenital heart disease. Physical activity should also be promoted in an individualized manner, taking into account gender, disease severity, and parental attitude.

A Study Using Visual Art Methods to Explore the Perceptions and Barriers of Self-Management in Children and Adolescents with Lymphedema

Background: The aims of this study were to explore, using visual art methodology, how children and adolescents perceive their lymphedema and conceptualize the barriers and enablers in self-management and to explore the role of an educational camp in promoting self-efficacy. Methods: Participants (speaking English, French, and Italian) were recruited during an educational camp for children with lymphedema. Children and adolescents used different methodologies to depict living and self-managing their condition. Younger children (aged 5-12 years) drew pictures, and all children and adolescents (aged 5-18 years) were given cameras and asked to take photographs that depicted their experience of learning self-management of their condition during the camp. Rose's critical visual methodology framework was used for analysis. Results: Analysis of the data produced five categories: Normal versus altered childhood, living with lymphedema; perceptions of lymphedema and self-care in younger children; adolescents' perception of living and managing lymphedema; learning self-efficacy; and insights into cultural differences in self-care. Conclusions: The study has shown that self-management is complex. Children and adolescents face many daily challenges and frustrations in managing their condition in addition to the normal challenges of development and growth that impact on: home life, time with friends, school activities, and relationships. Children expressed a deep longing for cure and a recognition that their lives were altered by having the condition that led to limitations in sport and wearing fashionable clothes and shoes. The importance of relationships with professionals was critical as was the experience of meeting and learning with other children through the camp experience. Attempts to simplify self-management techniques would appear to be a key priority as would a greater understanding of the self-beliefs young people have of their ability to influence and control their condition and its impact on their life.

A Study to Explore the Parental Impact and Challenges of Self-Management in Children and Adolescents Suffering with Lymphedema

Background: Limited research has shown the impact lymphedema has on children and families. The aim of this study was to explore the parental experience of caring for a child or adolescent with lymphedema and the daily challenges of self-management and self-efficacy. Methods and Results: Participants were recruited during an educational camp for children with lymphedema (N = 26). Three individual semistructured focus groups were undertaken in English, French, and Italian with simultaneous translation. Data were analyzed using interpretative phenomenological analysis. Analysis identified four superordinate themes; the journey, treatment management, independence, and psychosocial impact. Ten subthemes were identified: bandaging/compression, professional support, holistic care, fear, self-efficacy, acceptance, friendship, guilt, distress, and hope. Conclusions: Parental self-management of children with lymphedema is complex and invades many aspects of life. Lack of professional agreement over what constitutes self-management leads to parental confusion and anxiety. Self-management is demanding, and parents are ambivalent to its effectiveness, but choose to persevere through fear of their child's condition deteriorating. Self-efficacy is evident in complex problem solving, despite parents believing that they are not adequately prepared for this.

Physical activity levels and self-efficacy of Greek children with congenital heart disease compared to their healthy peers

OBJECTIVE

It remains a challenge for children with congenital heart disease (CHD) to develop healthy lifestyle behaviors. This study investigates the interrelationship of physical activity and self-efficacy levels in Greek children with corrected CHD and compares them with those of healthy controls.

METHODS

A prospective cross-sectional study of 76 patients with operated CHD and 78 healthy volunteers (n = 154) was conducted. The Self Efficacy Scale and Previous Day Physical Activity Recall self-reporting questionnaires were used to assess self-efficacy and physical activity, respectively. Calculated metabolic equivalent of task (MET) provided an indication of participation in moderate and vigorous physical activities.

RESULTS

Mean physical self-efficacy in children with CHD was 29.01 ± 7.28, while that in healthy volunteers was 29.04 ± 6.60 (p = 0.076). Average physical activity levels-METs in children with CHD (2.38 ± 0.85) were significantly lower than those in controls (3.1 ± 0.95). Physical self-efficacy and physical activity were positively correlated (r = 0.515, p = 0.001), thus indicating that children with higher self-efficacy engaged in more vigorous physical activities. In children with CHD, self-efficacy was quite important in predicting physical activity, thus explaining almost ¼ of the variability in observed activities.

CONCLUSION

The low physical activity levels exhibited by Greek children with corrected CHD can lead to a sedentary adult lifestyle. Improving physical self-efficacy may help encourage them and consequently increase their physical activity levels. School-based education initiatives and athletic programs can play an important role in improving this.

Psychosocial situation in adults with congenital heart defects today and 20 years ago: Any changes?

BACKGROUND

While diagnosis and treatment of congenital heart diseases have improved over the last two decades, data regarding the course of psychosocial parameters is missing.

METHODS

In a cross-sectional study, 283 adults with congenital heart disease completed a slightly modified questionnaire that was applied in a comparable study twenty years ago. Significant differences between the two populations as well as possible predictors of psychosocial burden for the recent population were sought.

RESULTS

Despite the presence of more complex heart defects in the current cohort (p < 0.001), both populations exhibited similar values in the Ability Index. Furthermore, the current cohort reported significantly improved outcomes regarding school performance, employment, and sports. Regarding psychosocial functioning, the current cohort showed better outcomes in the domains of sadness (p < 0.01), independence (p < 0.01), understanding (p < 0.001), and acceptance (p < 0.01) of heart disease. Predictors for a worse psychosocial situation in a multiple regression analysis were anxiety, lack of curiosity, and age over 33. In the current study women, as opposed to men, reported significantly more dissatisfaction with too little information provided about their illness (p < 0.05), higher anxiety levels (p < 0.01), and heightened illness-connected burden (p < 0.05). However, women showed higher levels of independence (p < 0.01) and lower alcohol consumption (p < 0.001).

CONCLUSION

The psychosocial situation of adults with congenital heart disease has improved over the span of 20 years. However, particular needs and concerns should be addressed individually via doctor-patient communication. The findings here suggest that especially female patients appear to have a higher demand for counselling information, e.g. reproduction issues.

Adapted Motivational Interviewing to Promote Exercise in Adolescents With Congenital Heart Disease: A Pilot Trial

PURPOSE

To assess a motivational interviewing (MI) intervention to improve moderate-to-vigorous physical activity (MVPA) in adolescents with congenital heart disease.

METHODS

Intervention participants received one-on-one telephone-based adapted MI sessions over 3 months. Outcomes were acceptability, change mechanisms (stage of change and self-efficacy), and limited efficacy (physical activity, fitness, and quality of life).

RESULTS

Thirty-six participants were randomized. Intervention participants completed 4.2 ± 1.2/6 MI sessions, with no improvements in the high self-efficacy or stage of change observed. Participants accumulated 47.24 ± 16.36 minutes of MVPA/day, and had comparable outcomes to peers without heart disease (except for functional capacity). There was no significant difference in change in any outcome by group.

CONCLUSIONS

The intervention was acceptable, but effectiveness could not be determined due to the nature and size of sample.

CLINICAL RELEVANCE

Pediatric cardiac rehabilitation remains the sole effective intervention to increase MVPA in this population.

Self-efficacy as a predictor of patient-reported outcomes in adults with congenital heart disease

Objective:

Self-efficacy is a known predictor of patient-reported outcomes in individuals with acquired diseases. With an overall objective of better understanding patient-reported outcomes in adults with congenital heart disease, this study aimed to: (i) assess self-efficacy in adults with congenital heart disease, (ii) explore potential demographic and medical correlates of self-efficacy and (iii) determine whether self-efficacy explains additional variance in patient-reported outcomes above and beyond known predictors.

Methods:

As part of a large cross-sectional international multi-site study (APPROACH-IS), we enrolled 454 adults (median age 32 years, range: 18–81) with congenital heart disease in two tertiary care centres in Canada and Switzerland. Self-efficacy was measured using the General Self-Efficacy (GSE) scale, which produces a total score ranging from 10 to 40. Variance in the following patient-reported outcomes was assessed: perceived health status, psychological functioning, health behaviours and quality of life. Hierarchical multivariable linear regression analysis was performed.

Results:

Patients’ mean GSE score was 30.1 ± 3.3 (range: 10–40). Lower GSE was associated with female sex ( p = 0.025), not having a job ( p = 0.001) and poorer functional class ( p = 0.048). GSE positively predicted health status and quality of life, and negatively predicted symptoms of anxiety and depression, with an additional explained variance up to 13.6%. No associations between self-efficacy and health behaviours were found.

Conclusions:

GSE adds considerably to our understanding of patient-reported outcomes in adults with congenital heart disease. Given that self-efficacy is a modifiable psychosocial factor, it may be an important focus for interventions targeting congenital heart disease patients’ well-being.

Remote Lifestyle Counseling Influences Cardiovascular Health Outcomes in Youth with Overweight or Obesity and Congenital Heart Disease

BACKGROUND

Children with overweight/obesity and congenital heart disease (CHD) are at increased cardiovascular risk. A lifestyle intervention may help reduce these risks. We sought to determine the feasibility of a smartphone-based lifestyle intervention to improve cardiovascular health outcomes in children with overweight/obesity and CHD.

METHODS

We examined the effect of bi-weekly nutrition and fitness counseling delivered via smartphone over 12 months. Thirty-four youth, previously diagnosed with CHD and with overweight or obesity, participated in the intervention. They were divided into two groups depending on whether the heart disease required surgical correction (operated, n = 19) or not (non-operated, n = 15). Anthropometry, body composition cardiorespiratory exercise capacity, and cardio-metabolic risk factors were assessed at baseline, 6 months, and 12 months.

RESULTS

Statistically significant decreases in waist circumference (WC), body mass index z-score, WC z-score, and waist to height ratio z-score were observed at 6 and 12 months in the operated group. A significant linear increase in lean body mass was observed in both groups. The study also had a high retention rate and a low attrition rate.

CONCLUSION

The observed changes in anthropometry were positive with significant improvement to some cardiovascular and metabolic risk indicators. However, this was only observed in the operated group suggesting that other factors, such as perception of condition and self-efficacy, may influence lifestyle behaviors. The results from this pilot study clearly demonstrate the feasibility to perform a larger controlled study on remote lifestyle intervention in children with congenital heart defects and overweight or obesity.

Exercise Capacity and Self-Efficacy are Associated with Moderate-to-Vigorous Intensity Physical Activity in Children with Congenital Heart Disease

This study sought to determine whether exercise capacity, self-efficacy, and gross motor skills are associated with moderate-to-vigorous physical activity (MVPA) levels in children, and if these associations differ by congenital heart disease (CHD) type. Medical history was abstracted from chart review. We assessed MVPA levels (via accelerometry), percent-predicted peak oxygen consumption ([Formula: see text] cardiopulmonary exercise test), gross motor skill percentiles (test of gross motor development version-2), and self-efficacy [children's self-perceptions of adequacy and predilection for physical activity scale (CSAPPA scale)]. CHD patients (n = 137, range 4-12 years) included children with a repaired atrial septal defect (n = 31, mean ± standard deviation MVPA = 454 ± 246 min/week), transposition of the great arteries after the arterial switch operation (n = 34, MVPA = 423 ± 196 min/week), tetralogy of Fallot after primary repair (n = 37, MVPA = 389 ± 211 min/week), or single ventricle after the Fontan procedure (n = 35, MVPA = 405 ± 256 min/week). MVPA did not differ significantly between CHD groups (p = 0.68). Higher MVPA was associated with a higher percent-predicted [Formula: see text] (EST[95% CI] = 16.9[-0.2, 34] MVPA min/week per 10% increase in percent-predicted [Formula: see text] p = 0.05) and higher self-efficacy (EST[95% CI] = 5.2[1.0, 9.3] MVPA min/week per 1-unit increase in CSAPPA score, p = 0.02), after adjustment for age, sex, and testing seasonality, with no association with CHD type. Higher MVPA was not associated with gross motor skill percentile (p = 0.92). There were no significant interactions between CHD type and percent-predicted [Formula: see text] self-efficacy scores, and gross motor skill percentiles regarding their association with MVPA (p > 0.05 for all). Greater MVPA was associated with higher exercise capacity and self-efficacy, but not gross motor skills.

The Influence of Exercise Training on Quality of Life and Psychosocial Functioning in Children with Congenital Heart Disease:A Review of Intervention Studies

Children and adolescents operated upon for congenital heart disease may show reduced exercise capacity and physical activity, associated with lowered quality of life. This review presents intervention studies on the influence of an exercise program on quality of life and psychosocial functioning in children with severe congenital heart disease. Participation in an exercise program among young people with complex congenital heart disease seemed to have positive effects on quality of life and passive leisure time spent. However, more effects of the exercise programs may have been expected. For future research it is important to critically evaluate the content of the exercise programs.

Rehabilitation during congenital heart disease in pediatric patients

Cardiac rehabilitation is an important part of daily routine for cardiac disorder patients in adults. However, pediatric rehabilitation is an emerging field, and is totally different and new field in case of pediatric patients. The main reason of variability is the Pediatric patients differ from adult patients in several ways. The main difference is they are dependent on their parents for meeting their needs, including for transportation and following of rehabilitation initiatives. Furthermore, rehabilitation initiatives are often connected to large urban university hospitals and unavailable to children whose parents cannot bring them for exercise training on a regular basis. The present review article is focused on these aspects of rehabilitation during congenital heart disease.

Physical activity and its correlates in children and adolescents post-liver transplant

The health benefits of PA are well established for healthy and chronically ill children. This study objectively measures physical fitness and PA levels in children PLT and explores potential correlates and perceived barriers impacting their PA. A total of 23 children (16 females, mean 14.01 ± 2.49 yrs) >1 yr PLT were assessed for peak oxygen consumption (VO2 peak), muscle strength, endurance, and flexibility. MVPA and steps/day were determined with accelerometry. Additionally, SE, perceived fatigue, and barriers and benefits of PA were examined. VO2 peak (mean 33. 2 ± 7.61 mL/kg/min; 77.0 ± 15.6% predicted) and PA (average 6841 ± 2299 steps/day) were below healthy norms. MVPA (31.6 ± 16.1 min/day) was lower than national guidelines. Six participants (30%) attained criterion standards for abdominal strength and one participant (5%) for push-ups. Fatigue and SE were lower than reported levels in healthy children. A commonly perceived barrier to PA was "I am tired." A positive correlation was shown between SE and MVPA (r = 0.57, p = 0.007), SE and fatigue (r = 0.54, p = 0.01), and PELD score and fatigue (r = 0.66, p = 0.007). Children PLT demonstrate below normal levels of PA and aerobic capacity. SE is a modifiable correlate of their PA. Further investigation of the impact of PA correlates can guide the development of future innovative PA intervention strategies in children PLT.

Assessment of Transition Readiness in Adolescents and Young Adults with Heart Disease

OBJECTIVES

To evaluate transition readiness, including perceived knowledge deficits, self-efficacy, and self-management behaviors, in 13- to 25-year-olds with congenital heart disease or heart transplant and to examine the relationships between transition readiness assessment, information seeking behavior, and quality of life (QOL).

STUDY DESIGN

In this cross-sectional study, patients (n = 164) completed the Transition Readiness Assessment and the Pediatric Quality of Life Inventory using an e-tablet, web-based format at a routine clinic visit.

RESULTS

Median patient age was 18.1 years (range 13.0-25.5). Average perceived knowledge deficit score (% of items with no knowledge) was 25.7% (range 0%-75%). On a 100-point scale, the mean score was 72.0 ± 17.2 for self-efficacy and 49.7 ± 17.5 for self-management. Knowledge deficits were negatively correlated with self-efficacy (r = -0.45, P < .0001) and self-management (r = -0.36, P < .0001). Overall, 66% of patients requested information (73% ≥ 18 years old). Higher psychosocial QOL scores were correlated with lower knowledge deficit scores (r = -0.21, P = .01) and higher perceived self-efficacy scores (r = 0.41, P < .0001).

CONCLUSIONS

Transition knowledge deficits are common and associated with decreased self-efficacy and self-management skills in adolescents and young adults with heart disease. Greater transition knowledge and perceived self-efficacy are associated with better psychosocial QOL. Routine assessment of transition readiness is recommended to facilitate recognition of deficits and interventions to promote successful transition outcomes.

Parental mental health moderates the efficacy of exercise training on health-related quality of life in adolescents with congenital heart disease

To evaluate the moderating influence of parental variables on changes in health-related quality of life (HRQoL) in adolescents with Tetralogy of Fallot (ToF) or a Fontan circulation after participation in standardized exercise training. A multicenter randomized controlled trail in which 56 patients, aged 10-15, were randomly allocated (stratified by age, gender, and congenital heart disease) to a 12-week period with either: (a) 3 times per week standardized exercise training or (b) care-as-usual (randomization ratio 2:1). Adolescents and their parents filled in online questionnaires at baseline and at 12-week follow-up. In this randomized controlled trail, primary analyses involved influence of parental mental health and parental social support for exercise on changes in the TNO/AZL Child Quality of Life Questionnaire Child Form at follow-up. Secondary analyses concerned comparing levels of parental characteristics with normative data. Compared with controls, adolescents in the exercise group reported a decrease in social functioning when their parents had more anxiety/insomnia or severe depression themselves. Adolescents also reported a decrease in social functioning when their parents showed poorer overall mental health themselves. Parents reported comparable or even better mental health compared with normative data. The effect of a standardized exercise program on HRQoL changes in adolescents with ToF or a Fontan circulation is moderated by parental mental health, more specifically by parental anxiety/insomnia and severe depression. The trial registration number of this article is NTR2731 ( www.trialregister.nl ).
