Clinical Trial Summary

The Congenital Heart Disease Physical Activity Lifestyle Intervention Study (CHD-PALS) V.2 seeks to determine the efficacy of a lifestyle intervention program for adolescents and young adults (AYAs) with congenital heart disease (CHD). This trial was adapted from the original CHD-PAL trial to continue improving cardiovascular outcomes for transition-aged CHD survivors.


Description:

Current estimates indicate more than 2 million individuals in the United States have CHD. CHD survivors are now living well into adulthood, including those with moderate and complex forms of CHD, who previously did not survive childhood. However, adult CHD survivors are now encountering cardiovascular comorbidities, such as coronary disease and hypertension, costing more than $3.16 billion annually in hospitalizations and resulting in premature death. The benefits of physical activity for preventing coronary artery disease and other cardiac comorbidities are well-known. For CHD survivors, the benefits of physical activity for preventing morbidity and premature mortality have also been emphasized. Despite strong evidence for physical activity preventing and treating acquired cardiovascular comorbidities among CHD survivors, adolescents and young adults (AYAs) with CHD do not meet recommended activity levels. The CHD-PAL intervention aims to provide individualized guidance on safe forms of physical activity that is delivered by trained allied health interventionists. The CHD-PAL intervention is informed by the Theory of Planned Behavior (TPB) which has been used as a framework for lifestyle interventions, including among adults with heart failure and adolescents. Additionally, the CHD-PAL intervention implements goal-setting (or developing action plans) and self-monitoring, both of which are key for enacting the behavior within the TPB. Investigators will randomize (1:1) 144 AYAs (ages 15-25) with moderate and complex CHD who spend <=30 minutes/day in moderate to vigorous physical activity (MVPA) to 1 of 2 arms: CHD-PAL or attention control (Control). Both arms will receive a FitbitĀ® and a tailored exercise prescription. Those in CHD-PAL will also receive a 20-week videoconferencing-administered intervention that includes 9, 20 to 30-minute sessions designed to increase positive attitudes towards, subjective norms for, and perceived control for engaging in physical activity. Self-monitoring and goal-setting will also be encouraged to help enact behavior change. Controls will receive the same number/frequency of videoconferencing contacts to discuss the Fitbit and exercise prescription, as well as general healthy living, without addressing the TPB hypothesized mechanisms. Controls will also not be directed to self-monitor or engage in goal-setting. All participants will receive text messages from interventionists to either reinforce session content and inquire about progress towards goals (CHD-PAL) or to remind participants to wear the Fitbit (Control). Randomization will be stratified by gender and age using randomly varying block sizes of 4 to 6. MVPA, as measured with a research-grade accelerometer, will be assessed at baseline (T1), post-intervention (T3; 20 weeks after baseline), interim follow-up (T4; 20 weeks post-intervention), and follow-up (T5; 40 weeks post-intervention). TPB mechanisms will be similarly assessed, with the addition of an interim assessment during the intervention (T2; 10 weeks after baseline). Cardiorespiratory fitness (peak volume of oxygen consumption (VO2) and metabolic equivalent (METs)), as assessed via stress testing, will be measured at T1 and T3 as exploratory secondary outcomes. The primary aim is to determine the efficacy of the CHD-PAL intervention on change in time spent in moderate to vigorous physical activity (MVPA) for AYAs with moderate and complex CHD. The secondary aim is to explore change in the TPB mechanisms and their relevance to change in MVPA. The tertiary aim is exploring the impact of CHD-PAL on cardiorespiratory fitness.

Study Design


Intervention

Behavioral:
Physical Activity Monitoring
A physical activity monitor (Fitbit) will be provided to participants in both arms.
Tailored Exercise Prescription
Participants in both arms will receive the results of their exercise stress test, which includes information on the duration, frequency, and intensity of their physical activity.
Healthy Lifestyle Education
Participants in both arms will receive information on healthy living, including topics such as physical activity, sleep, stress management, and diet.
Physical Activity Lifestyle Intervention Informed by the Theory of Planned Behavior
Participants randomized to the CHD-PAL arm will receive coaching to: 1) change attitudes towards physical activity; 2) increase perceptions of other people's approval of physical activity; 3) increase perceptions of control over being physically active. These elements will be delivered using a non-judgmental stance and will be accompanied by goal-setting.

Outcome

Type Measure Description Time frame Safety issue
Other Cardiorespiratory Fitness-Volume of Oxygen Consumption (Peak VO2) Peak VO2 is the highest value of oxygen consumption during an exercise stress test and is widely used as an indicator of cardiorespiratory fitness. Peak VO2 will be measured at baseline and post-intervention to examine the impact of CHD-PAL on change in biological markers of cardiovascular health. Baseline to Week 20
Other Cardiorespiratory Fitness- Metabolic Equivalents (METs) MET scores, or metabolic equivalents, represent the amount of oxygen consumed at rest or during activity. It is a simple, practical way to express the energy cost of different physical activities. METs, as assessed during the exercise stress test, will be measured at baseline and post-intervention to examine the impact of CHD-PAL on change in biological markers of cardiovascular health. METs are calculated by: ([miles per hour x 26.8 x 0.1] + [grade/100 x 1.8 x miles per hour x 26.8] + 3.5)/3.5 and the highest MET achieved during the stress test will be abstracted. Baseline to Week 20
Primary Moderate to Vigorous Physical Activity (MVPA) Number of minutes spent in moderate to vigorous physical activity as measured by an accelerometer. Baseline to Weeks 20, 40, and 80
Secondary Physical Activity Enjoyment/Engagement Scale (Attitudes) 18-item measure of enjoyment and dislike of physical activity in which the participant currently engages. Each item is rated on a 7-point Likert scale with a positive attitude (e.g., I enjoy it) and negative attitude (e.g., I hate it) towards physical activity on each end. Baseline to Weeks 10, 20, 40, and 80
Secondary Affective Attitudes for Physical Activity Scale (Attitudes) 4-item measure of affective physical activity attitudes using bipolar adjectives on a 7-point Likert scale (i.e., enjoyable-unenjoyable, boring-interesting, pleasant-unpleasant, stressful-relaxing). Baseline to Weeks 10, 20, 40, and 80
Secondary Physical Activity Norms Measure (Social Norms) 5-item measure of perceptions of subjective norms of physical activity (e.g. "Members of my family think I should be physically active regularly"). An additional item was added to assess norms of cardiologist. Original item wording of "during my free time on most days" was changed to "regularly." Participants are presented with a 5-point Likert scale ranging from "Strongly disagree" to "Strongly agree." One item ("Compared to others of your age and sex, mark how active you are.") is measured on a 5-point Likert scale ranging from "Much less active" to "Much more active." Baseline to Weeks 10, 20, 40, and 80
Secondary Family and Partner Support for Physical Activity Engagement Measure (Social Norms) 39-item measure asking participants to indicate "None," "Rarely," "A few times," Often," "Very often," and "Does not apply," when rating the extent to which family (i.e., parents, siblings) and friends provided support for physical activity in different contexts within the past 3 months. This measure has been modified to include items for partners. Baseline to Weeks 10, 20, 40, and 80
Secondary Perceived Control for Physical Activity Engagement Measure (Perceived Control) 5-item measure of perceived control for engaging in regular physical activity. Wording was adapted to use "physical activity" instead of "exercise". Each item is rated on a 7-point Likert scale with a negative perception of control (e.g., Very little control) and positive perception of control (e.g., Complete control) of physical activity engagement on each end. Baseline to Weeks 10, 20, 40, and 80
Secondary Exercise Confidence Survey (Perceived Control) 12-item questionnaire assessing health-related self-efficacy in adjusting physical activity behaviors. The original questionnaire has items for self-efficacy in diet behaviors, which have been removed for the purpose of this study. Wording has also been modified to reflect "physical activity"/"physically active" language. Items are measured on a 5-point Likert scale from "I know I cannot" to "I know I can" with an additional option of "Does not apply." Baseline to Weeks 10, 20, 40, and 80
