Physical activity perceptions and behaviors among young adults with congenital heart disease: A mixed-methods study

Children With Congenital Heart Disease and the Canadian 24-Hour Movement Guidelines: A Scoping Review

Factors such as physical activity (PA), sedentary time, screen time, and sleep affect the holistic health of children with congenital heart disease (CHD). Despite this, their proximity to reaching the Canadian 24-hour movement guidelines is unknown. This review sought to synthesize evidence for PA, sedentary time, screen time, and sleep behaviour of children with CHD and compare them with the Canadian 24-hour movement guidelines. Six online databases were searched for research published from January 2010 to May 2024. Eligible articles included research involving children aged 4-20 years with any type of CHD lesion as well as a measure of one of PA, sedentary time, screen time, or sleep, reported in a unit of time. The search resulted in 9199 articles, and after removing ineligible articles, 30 were identified for this review. Of the included articles, 30 measured moderate-to-vigorous PA (MVPA), 8 measured light PA, 14 measured sedentary time, 1 measured screen time, and 3 measured sleep time. Forty percent of studies reported that children with CHD met the MVPA guidelines. Within these, a subset of studies (n = 20) examined the percentage of the sample that reached the guideline and found that an average of 43% of children with CHD attained the MVPA guideline. No conclusions could be made for light PA or sedentary time because there is no clear quantification or numerical recommendation in the Canadian 24-hour movement guidelines. In addition, future research should include evaluations of the screen and sleep time of children with CHD due to very limited research in the area.

Strategies to Overcome Barriers to Physical Activity Participation in Children and Adults Living With Congenital Heart Disease: A Narrative Review

Physical activity participation is critical for optimal physical, psychological, and cognitive health in children and adults living with congenital heart disease (CHD). Majority of the general population are not sufficiently active, and with the added psychological, physical, and socioeconomic barriers faced by individuals with CHD, it is unsurprising that many people living with CHD do not meet the recommendations for physical activity either. The aim of this review is to outline lifelong physical activity barriers faced by individuals living with CHD and provide age-appropriate strategies that can be used to ensure the development of long-term positive physical activity behaviours. Barriers to physical activity include safety fears, lack of encouragement, low exercise self-efficacy, body image concerns, limited education, socioeconomic status, reduced access to resources, and cardiac diagnosis and severity. These barriers are multifaceted and often begin in early childhood and continue to develop well into adulthood. Therefore, it is important for children to participate in physical activity from early stages of life as it has been shown to improve cardiorespiratory fitness, muscular endurance, and quality of life. Current literature demonstrates that participation in physical activity and higher intensity exercise after appropriate screening is safe and should be encouraged rather than dissuaded in people born with a congenital heart condition.

Parental recommendations and exercise attitudes in congenital hearts

BACKGROUND

Children and young people with CHD benefit from regular physical activity. Parents are reported as facilitators and barriers to their children's physical activity. The aim of this study was to explore parental factors, child factors, and their clinical experience on physical activity participation in young people with CHD.

METHODS

An online questionnaire was co-developed with parents (n = 3) who have children with CHD. The survey was then distributed in the United Kingdom by social media and CHD networks, between October 2021 and February 2022. Data were analysed using mixed methods.

RESULTS

Eighty-three parents/guardians responded (94% mothers). Young people with CHD were 7.3 ± 5.0 years old (range 0-20 years; 53% female) and 84% performed activity. Parental participation in activity (X2(1) = 6.9, P < 0.05) and perceiving activity as important for their child were positively associated with activity (Fisher's Exact, P < 0.05). Some parents (∼15%) were unsure of the safety of activity, and most (∼70%) were unsure where to access further information about activity. Fifty-two parents (72%) had never received activity advice in clinic, and of the 20 who received advice, 10 said it was inconsistent. Qualitative analysis produced the theme "Knowledge is power and comfort." Parents described not knowing what activity was appropriate or the impact of it on their child.

CONCLUSION

Parental participation and attitudes towards activity potentially influence their child's activity. A large proportion of young people performed activity despite a lack and inconsistency of activity advice offered by CHD clinics. Young people with CHD would benefit from activity advice with their families in clinics.

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).

Ambivalence is associated with decreased physical activity and cardiorespiratory fitness among adolescents with critical congenital heart disease

BACKGROUND

Adolescents with congenital heart disease (CHD) are insufficiently physically active. Given that increasing physical activity may reduce their cardiovascular risk, it is important to identify correlates of this behavior. Perceived benefits of and barriers to physical activity are associated with physical activity engagement. Existing research has only considered these constructs separately. This population may be ambivalent toward physical activity (i.e., perceive both strong benefits and barriers). The association of ambivalence and physical activity related outcomes is unknown among this at-risk population.

OBJECTIVE

Determine the association of ambivalence and sedentary behavior, moderate-to-vigorous physical activity (MVPA), and cardiorespiratory fitness (VO2Peak) among adolescents with CHD.

METHODS

The present study is an analysis of data from an eligibility assessment for a randomized clinical trial of an intervention to promote MVPA among adolescents aged 15 to 18 years with moderate or complex CHD. Participants (N = 84) completed a survey assessing perceived benefits and barriers from which ambivalence toward physical activity was calculated, an exercise stress test to measure VO2Peak, and wore an accelerometer for one week to determine their engagement in sedentary behavior and MVPA. Linear regression analyses determined associations between ambivalence and physical activity related outcomes. RESULTS: Greater ambivalence toward physical activity was associated with increased sedentary behavior, decreased MVPA, and reduced VO2Peak, adjusting for demographic and clinical covariates.

CONCLUSIONS

Ambivalence is associated with objectively measured physical activity (sedentary behavior, MVPA) and a biomarker of cardiovascular health (VO2Peak). Screening for ambivalence may help clinicians identify those most likely to benefit from physical activity-related education.

Cardiopulmonary Fitness of Preschoolers with Congenital Heart Disease: An Observational Study

With advancements in cardiopulmonary rehabilitation over the past few decades, the survival rate of patients with congenital heart disease (CHD) has increased. However, the Cardiopulmonary fitness (CPF) of these patients is poor. Here, we aimed to investigate CPF in preschoolers with CHD (aged 4 to 6 years) using cardiopulmonary exercise testing. We retrospectively compared 102 healthy preschoolers with 80 preschoolers with CHD. The latter had lower peak oxygen consumption, oxygen consumption at anaerobic threshold and metabolic equivalent at anaerobic threshold. The same result was observed in boys with CHD, but not in girls, when sex was sub-analyzed. Considering the body composition, children with CHD had a lower fat-free mass index (FFMI) than their healthy peers. Healthy preschoolers with a normal body mass index (BMI) had higher anaerobic threshold and peak metabolic equivalent values than overweight or underweight children. This was categorized under the BMI reference of the Ministry of Health and Welfare in Taiwan. In conclusion, the CPF difference between the CHD and healthy groups was identified as early as in preschool age, and better CPF in healthy preschoolers within the normal BMI range suggests the importance of weight control in young children.

Fearless in Physical Activity: The Implications of Community-Based Physical Activity Interventions on Children, Adolescents, and Adults with Congenital Heart Disease

People living with CHD do less moderate-to-vigorous activity than their peers. This study sought to examine the impact of a community-based physical activity intervention for individuals with CHD. Individuals with CHD and family members participated in a 3 h, one-day Fearless event consisting of a variety of physical activity and education sessions. Consenting participants completed self-administered questionnaires pre-/post-event and completed a post-event feedback form. Descriptive statistics and paired t-tests were calculated across subgroups for each outcome/questionnaire. Written feedback was analyzed using a six-phase framework of reflexive thematic analysis. A total of 32 participants (six children, six adolescents, five youth, five all ages, and ten adults) with CHD completed this study. Following Fearless, youth with CHD reported spending less time being 'inactive' and more time being 'somewhat active'. Adults with CHD reported spending more time walking and partaking in moderate activity and less time partaking in vigorous activity. Fearless successfully engaged individuals with CHD who were more sedentary, less active, and older. Fearless is a fun, family-friendly, physical activity intervention for individuals with CHD. Attending a Fearless event helped children, adolescents, and adults with CHD make incremental improvements to their physical activity levels and provided a framework for sport and recreation leaders who aim to promote physical activity amongst individuals with CHD.

Reduced Physical Activity During COVID-19 in Children With Congenital Heart Disease: A Longitudinal Analysis

Background

Coronavirus disease 2019 (COVID-19) was associated with a reduction in physical activity in children with congenital heart disease (CHD) in early 2020. Given the increased cardiovascular risk of this population, optimizing cardiovascular health behaviour is important. The aim of the study is to determine how the ongoing COVID-19 pandemic has impacted longitudinal physical activity measures in children with CHD.

Methods

As part of a prospective cohort study, children and adolescents aged 9-16 years old with moderate-to-complex CHD were recruited from British Columbia Children's Hospital and partnership clinics across British Columbia and the Yukon territory. Daily step counts were measured continuously over 3 years (2018-2021) with Fitbit Charge 2. School status during the COVID-19 pandemic was assessed with parent- or self-report survey.

Results

A total of 102, 114, and 93 participants had valid Fitbit data during 2018, 2019, and 2020, respectively. There was a significant reduction in the annual mean step count for 2020 (8225 ± 4328 steps) compared with both 2018 (9416 ± 3770 steps) and 2019 (9533 ± 4114 steps) (P < 0.001). There was a loss of seasonal variation in physical activity, and reduced levels of physical activity persisted when most children resumed in-person schooling in September 2020.

Conclusions

We demonstrated a significant decrease in physical activity and loss of seasonal patterns in children with CHD during 2020. These findings represent a worsening of the cardiovascular risk profile in children with CHD, who are already at an increased risk of adverse cardiovascular outcomes. Mitigation strategies are needed to optimize the cardiovascular health status of children with CHD as the pandemic persists.

Inactive Lifestyles among Young Children with Innocent Murmurs or Congenital Heart Disease Regardless of Disease Severity or Treatment

BACKGROUND

Sedentary lifestyle morbidities are common among children with congenital heart disease (CHD). Understanding the physical activity trajectory from early childhood could enhance intervention timing/effectiveness.

METHODS

154 children (56% male) were recruited at 12-47 months of age for this prospective, longitudinal, observational study. Physical activity and sedentary behaviour (7-day accelerometry) and motor skill (Peabody Developmental Motor Scales-2) were assessed every 8 months until 5 years of age and then annually. Mixed effect repeated measures regression models described outcome trajectories across study assessments.

RESULTS

Children had an innocent heart murmur (n=28), CHD with insignificant hemodynamics not requiring treatment (n=47), CHD treated by catheterization or surgery without cardiopulmonary bypass (n=31), or CHD treated surgically with bypass (n=48). Motor skill was age appropriate (Peabody 49.0±8.4) but participants had lower physical activity (143±41 mins/day) and higher sedentary time (598±89 mins/day) than healthy peers, starting at 18 months of age. Movement behaviours were not related to treatment group (p>0.10), and physical activity was below the recommended 180 mins/day. Over time, physical activity, sedentary time and motor skill were primarily related to the baseline measure of each outcome (p<0.001).

CONCLUSIONS

Children with simple or complex CHD or innocent heart murmurs have an increased risk for sedentary lifestyles. Their physical activity and sedentary behaviours are established prior to 2 years of age, persist until school age, and are unrelated to motor skill. These results emphasize the need for interventions targeting the youngest children seen in a cardiac clinic, regardless of CHD diagnosis or innocent murmur.

Enablers and barriers for being physically active: experiences from adults with congenital heart disease

BACKGROUND

In general, adults with congenital heart disease have reduced exercise capacity and many do not reach the recommended level of physical activity. A physically active lifestyle is essential to maintain health and to counteract acquired cardiovascular disease, therefore enablers and barriers for being physically active are important to identify.

AIM

To describe what adults with complex congenital heart diseases consider as physical activity, and what they experience as enablers and barriers for being physically active.

METHODS

A qualitative study using semi-structured interviews in which 14 adults with complex congenital heart disease (seven women) participated. The interviews were analysed using qualitative content analysis.

RESULTS

The analysis revealed four categories considered enablers and barriers - encouragement, energy level, approach and environment. The following is exemplified by the category encouragement as an enabler: if one had experienced support and encouragement to be physically active as a child, they were more positive to be physically active as an adult. In contrast, as a barrier, if the child lacked support and encouragement from others, they had never had the opportunity to learn to be physically active.

CONCLUSION

It is important for adults with congenital heart disease to have the opportunity to identify barriers and enablers for being physically active. They need knowledge about their own exercise capacity and need to feel safe that physical activity is not harmful. This knowledge can be used by healthcare professionals to promote, support and eliminate misconceptions about physical activity. Barriers can potentially be transformed into enablers through increased knowledge about attitudes and prerequisites.

Cardiac rehabilitation in the paediatric Fontan population: development of a home-based high-intensity interval training programme

INTRODUCTION

We evaluated the safety and feasibility of high-intensity interval training via a novel telemedicine ergometer (MedBIKE™) in children with Fontan physiology.

METHODS

The MedBIKE™ is a custom telemedicine ergometer, incorporating a video game platform and live feed of patient video/audio, electrocardiography, pulse oximetry, and power output, for remote medical supervision and modulation of work. There were three study phases: (I) exercise workload comparison between the MedBIKE™ and a standard cardiopulmonary exercise ergometer in 10 healthy adults. (II) In-hospital safety, feasibility, and user experience (via questionnaire) assessment of a MedBIKE™ high-intensity interval training protocol in children with Fontan physiology. (III) Eight-week home-based high-intensity interval trial programme in two participants with Fontan physiology.

RESULTS

There was good agreement in oxygen consumption during graded exercise at matched work rates between the cardiopulmonary exercise ergometer and MedBIKE™ (1.1 ± 0.5 L/minute versus 1.1 ± 0.5 L/minute, p = 0.44). Ten youth with Fontan physiology (11.5 ± 1.8 years old) completed a MedBIKE™ high-intensity interval training session with no adverse events. The participants found the MedBIKE™ to be enjoyable and easy to navigate. In two participants, the 8-week home-based protocol was tolerated well with completion of 23/24 (96%) and 24/24 (100%) of sessions, respectively, and no adverse events across the 47 sessions in total.

CONCLUSION

The MedBIKE™ resulted in similar physiological responses as compared to a cardiopulmonary exercise test ergometer and the high-intensity interval training protocol was safe, feasible, and enjoyable in youth with Fontan physiology. A randomised-controlled trial of a home-based high-intensity interval training exercise intervention using the MedBIKE™ will next be undertaken.

"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.

Complex Determinants of Work Ability in Adults With Congenital Heart Disease and Implications for Clinical Practice

BACKGROUND

"Work ability" is the employees' capacity to meet the demands of their job. As more patients with complex congenital heart disease (CHD) are now reaching adulthood, we assessed work ability and factors impacting livelihood in adult CHD.

METHODS

The work ability index (WAI) questionnaire and patient health questionnaire-9 (PHQ-9) were administered at 2 Midwest adult CHD centres from February 2017 to 2018.

RESULTS

Of the 267 participants (n = 157 males, 59%) with an average age of 35 ± 13 years, the majority (n = 204, 76%) were employed. Patients with complex CHD (n = 103, 39%) were less likely to have enrolled in college or completed a graduate degree (P = 0.0115), and more likely to have an annual income of < $50,000 (P = 0.0056) and lower WAI scores (P = 0.0026) than patients with simple and moderate CHD. Unemployed patients (n = 63, 24%) with complex CHD (n = 27, 43%) were more likely to have higher PHQ-9 scores (P = 0.0242) indicating mild, moderate, or severe depression (P = 0.0482) than unemployed patients with simple and moderate CHD. Patients with complex CHD had lower self-perception of work ability compared with patients with simple and moderate CHD (P = 0.0007). Finally, patients in NYHA Functional Class I had higher WAI scores than NYHA Class III-IV (P < 0.0001).

CONCLUSIONS

This study demonstrates that employed patients with complex CHD have lower education level, income, and work ability. Unemployed patients are more likely to exhibit symptoms of depression and have low self-perception of work ability. Occupational health programs focusing on promoting general health perception, increasing exercise capacity, and improving psychosocial health must be considered to improve work ability in patients with adult CHD to maintain livelihood.

Teachers’ Opinions on the Use of Personal Learning Environments for Intercultural Competence

Background: The aim of the present study was to evaluate teachers’ opinions on the use of Personal Learning Environments (PLE) for the development of students’ intercultural competences. Methods: This investigation carried out a thematic analysis of semi-structured interviews applied to a sample of n = 100 Compulsory Secondary Education teachers in Andalusia (Spain) with an average teaching experience of 13.13 years (SD = 6.63). The interview shows excellent content validity (Content Validity Index for the interview overall, S-CVI = 0.94). The concordant codes and sub-codes were established in the analysis with the participation of two researchers and an external expert. Then, the data was analyzed using NVivo software. Results: The results show the opinions of the teachers grouped into six separate codes: intercultural learning communities, learning improvement, intercultural development of the student, disinformation, inapplicability, and inappropriate use. Conclusions: In general, it is concluded that the teachers consider the benefits of using PLE in the development of students’ intercultural competences. Despite this, some opinions reveal a lack of training and motivation, or the lack of ability teachers have on the subject, as well as in their classrooms, with the result that the PLE is not applicable for intercultural education.

Marfan syndrome in adolescence: adolescents' perspectives on (physical) functioning, disability, contextual factors and support needs

Although essential for providing optimal adolescent patient support, knowledge of the impact of Marfan syndrome in adolescence is limited. To explore adolescents' perceived impact of Marfan syndrome on (physical) functioning (activities, participation), disability (limitations, restrictions), contextual factors and support needs, we interviewed 19 adolescents with Marfan syndrome. Audio-recordings were transcribed, coded and analysed using thematic analysis. Identified themes were "difficulties in keeping up with peers" and "being and feeling different from peers". Furthermore, an adolescent Marfan syndrome-specific International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) model derived from the data describing the adolescent perceived impact of Marfan syndrome on functioning, disability and its contextual factors. Adolescents perceived problems in keeping up with peers in school, sports, leisure and friendships/relationships, and they could not meet work requirements. Moreover, participants perceived to differ from peers due to their appearance and disability. Contextual factors: coping with Marfan syndrome, self-esteem/image, knowledge about Marfan syndrome, support from family/friends/teachers, ability to express needs and peer-group acceptation acted individually as barrier or facilitator for identified themes.Conclusion: Adolescents with Marfan syndrome perceived limitations and restrictions in (physical) functioning. They perceived problems in keeping up with peers and perceived to differ from peers due to their appearance and disability. This warrants awareness and tailored physical, psychosocial, educational and environmental support programmes to improve (physical) functioning and empowerment of adolescents with Marfan syndrome.What is known:• Marfan syndrome is a hereditary connective tissue disorder.• Marfan syndrome affects multiple systems.What is new:• Adolescents with Marfan syndrome perceive (1) problems in keeping up with peers in school, sports, leisure, friendships/relationships and work (2) to differ from peers due to their appearance and disability.• An adolescent Marfan syndrome-specific International Classification of Functioning, Disability and Health for Children and Youth model derived from the data describing the adolescent perceived impact of Marfan syndrome on functioning, disability and contextual factors.
