Exercise Behavior in Adolescents With Mild Congenital Heart Disease

Perceptions of exercise behavior and well-being in anomalous aortic origin of coronary arteries

Anomalous aortic origin of a coronary artery (AAOCA) is associated with sudden death in the young. Risk stratification and management decision-making remain challenging. Data addressing post-diagnosis perceptions of exercise behavior and safety are lacking. We aimed to determine how AAOCA affects exercise behaviors, safety perceptions, and emotional well-being of patients/parents. Qualitative and quantitative analysis of AAOCA patient-/parent-specific survey was conducted to examine exercise frequency/restrictions, perceived safety of competitive/recreational exercise, and psychosocial well-being. Subgroups stratified by AAOCA subtype, surgical intervention, and physician-driven restrictions were compared using chi-squared and Fisher's exact tests. Cohen's kappa determined agreement in parent/child responses. AAOCA subtypes included 13 (24%) left AAOCA, 36 (67%) right AAOCA, and 5 (9%) other/unknown. Of 54 parents and 41 paired child responses, 22% of patients were physician-restricted from exercise. Parents imposed restrictions on competitive/recreational exercise 34%/26% of the time, respectively. Children without physician restrictions still self-restricted exercise 35% of the time. Parents reported feeling their child was unsafe exercising 61% competitively and 33% recreationally. Twenty-two percent of children reported feeling unsafe exercising, with good agreement to parental perceptions of competitive exercise safety (kappa = 0.779, p < 0.001). One-third of parents and children reported feeling sad, angry, or lonely, and about half reported feeling different. Importantly, 47% of children desired to exercise more. No difference was seen across restriction status, AAOCA subtype, or surgical management strategy.

CONCLUSION

There are different perceptions of exercise behavior and safety following AAOCA evaluation, regardless of risk category or management strategy, impacting their well-being. These unmet needs should be at the forefront of care.

WHAT IS KNOWN

• AAOCA is one of the leading causes of sudden cardiac death in the young. • Exercise restriction varies according to AAOCA subtype and its perceived risk of inducing myocardial ischemia.

WHAT IS NEW

• There are different perceptions of exercise behavior and safety in patients and parents following a diagnosis of AAOCA, impacting their well-being. • Risk category or management strategy has no effect in patients' and parents' perception of exercise safety. • These unmet needs in this population should be at the forefront of care.

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.

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.

A positive perspective of knowledge, attitude, and practices for health-promoting behaviors of adolescents with congenital heart disease

Background:

Health-promoting behaviors could serve as a major strategy to optimize long-term outcomes for adolescents with congenital heart disease. The associations assessed from a positive perspective of knowledge, attitudes, and practice model would potentially cultivate health-promoting behaviors during adolescence.

Aim:

The purpose of this study was to examine the relationships between disease knowledge, resilience, family functioning, and health-promoting behaviors in adolescents with congenital heart disease.

Methods:

A total of 320 adolescents with congenital heart disease who were aged 12–18 years were recruited from pediatric cardiology outpatient departments, and participated in a cross-sectional survey. The participants completed the Leuven Knowledge Questionnaire for Congenital Heart Disease; Haase Adolescent Resilience in Illness Scale; Family Adaptability, Partnership, Growth, Affection, and Resolve; and Adolescent Health Promotion scales. The collected data were analyzed using descriptive statistics and three multiple regression models.

Results:

Greater knowledge of prevention of complications and higher resilience had a more powerful effect in enhancing health-promoting behaviors. Having symptoms and moderate or severe family dysfunction were significantly more negatively predictive of health-promoting behaviors than not having symptoms and positive family function. The third model explained 40% of the variance in engaging in health-promoting behaviors among adolescents with congenital heart disease.

Conclusion:

The findings of this study provide new insights into the role of disease knowledge, resilience, and family functioning in the health-promoting behavior of adolescents with congenital heart disease. Continued efforts are required to plan family care programs that promote the acquisition of sufficient disease knowledge and the development of resilience for adolescents with congenital heart disease.

Physical Activity and Sedentary Behavior in Children With Congenital Heart Disease

Background

Children with congenital heart disease (CHD) are thought to have low levels of physical activity (PA), but few studies have used objective measures of PA in this population.

Methods and Results

We recruited patients with mild, moderate, and severe CHD and cardiac transplant recipients, aged 8 to 19 years, from pediatric cardiology clinics throughout British Columbia and Yukon, Canada. Participants were fitted with an ActiGraph accelerometer to be worn over the right hip for 7 days. Daily means were estimated for a variety of accelerometry‐derived metrics, including moderate‐to‐vigorous PA and percentage of sedentary time if they had at least 3 valid days of accelerometry data. Participants also completed a PA questionnaire. We included 90 participants (aged 13.6±2.7 years; 54% male), of which 26 had mild CHD, 26 had moderate CHD, 29 had severe CHD, and 9 were cardiac transplant recipients. Median daily moderate‐to‐vigorous PA was 43 min/day (interquartile range: 28.9–56.9 min/day), and 8% met PA guidelines of 60 minutes of moderate‐to‐vigorous PA at least 6 days a week. There were no significant differences in any accelerometry‐derived metric according to CHD severity. Boys were significantly more active and less sedentary than girls. Activity declined and sedentary behaviors increased with age in both sexes. Sports participation was common, including competitive out‐of‐school clubs (57%). PA restrictions from cardiologists were rare (15%).

Conclusions

We found normal age–sex patterns of PA in children with CHD. There were no differences in PA by CHD severity, suggesting that sociocultural factors are likely important determinants of PA in these children.

Social-cognitive determinants of exercise behaviour among adolescents with mild congenital heart disease

BACKGROUND

Nowadays, most adolescents with mild congenital heart disease (CHD) undergo medical or surgical correction in early childhood for their congenital anomalies. There is a need to examine the determinants of exercise behaviour among adolescents (CHD) who are able to exercise.

AIMS

The aims of this study were to examine determinants of exercise among adolescents with mild CHD, including personal beliefs about exercise, interpersonal influences on exercise, and availability of physical environments for exercise, based on social-cognitive theory.

METHOD

A repeated-measures study was conducted at three medical centres in Taiwan. All participants, 126 adolescents with CHD aged 12 to 18 years, had a cardiologist's recommendation of exercise with no limits or limits only on vigorous exercise. Self-administered questionnaires were completed during a summer vacation and again in the fall semester of school along with a 7-day exercise log. The data were analysed using structured equation modelling.

RESULTS

The effect of interpersonal influences on total exercise and moderate-to-vigorous exercise was mediated by personal exercise beliefs. Peer influences had significant effects on moderate-to-vigorous exercise through the mediator of perceived exercise self-efficacy. There was no significant difference in the determinants of exercise behaviour during two periods. Personal exercise beliefs, particularly perceived exercise self-efficacy, played the most important role in determining the performance of moderate-to-vigorous exercise.

CONCLUSIONS

The social-cognitive determinants may serve as a clinical reference for promoting exercise among adolescents with mild CHD.
