A Randomized Clinical Trial Demonstrating Feasibility and Preliminary Efficacy of a Videoconference-Delivered Physical Activity Lifestyle Intervention Among Adolescents With a Congenital Heart Defect.

ABSTRACT:

Background

Individuals with congenital heart defects are at increased risk for developing further cardiovascular complications, which can be mitigated by increasing physical activity. Given that positive health behaviors begin declining during older adolescence, it is vital to promote lifestyle changes in this population.

Purpose

The current study aims to (a) determine the feasibility/acceptability of the Congenital Heart Disease Physical Activity Lifestyle (CHD-PAL) intervention among adolescents (ages 15-18) with moderate and complex congenital heart defects, and (b) estimate the preliminary efficacy of CHD-PAL for increasing time spent in moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness and decreasing sedentary behavior.

Methods

Eligible participants were randomized into either CHD-PAL (eight 30-min videoconferencing sessions over 20 weeks with an interventionist + Fitbit + exercise prescription) or a comparator (Fitbit + exercise prescription).

Results

Sixty adolescents were randomized (76% recruitment rate; 94% of participants were retained from baseline to follow-up). Most adolescents (73%) and their parents/guardians (76%) reported that the trial was enjoyable. While there was no effect of arm on change in MVPA, sedentary behavior, or cardiorespiratory fitness for the entire sample, among those who engaged in <21 min of MVPA on average at baseline, adolescents in the CHD-PAL intervention had an increase of 16 min/day of MVPA more than comparators (d = 0.90).

Conclusions

The CHD-PAL intervention warrants examination in a larger trial to establish efficacy among those adolescents with a congenital heart defect who engage in <21 min of MVPA/day and should include follow-up assessments to examine effect durability.

Project description:Virtually supervised, group-based exercise presents an innovative way to expand the reach of exercise-oncology programs and help cancer survivors increase physical activity (PA) and connect with other participants. This study examined the feasibility, acceptability, and preliminary effects of a group-based PA program delivered exclusively using videoconferencing software. This study used a single-group pre-post design. The 8-wk program consisted of aerobic and resistance exercise sessions once per week and three PA behavior change discussion sessions in groups of four to six. Feasibility was determined by enrollment, retention, safety, and adherence. Postprogram surveys evaluated acceptability using a Likert scale and open-ended responses. Changes in PA (Godin Leisure-Time Exercise Questionnaire), quality of life (QOL; Functional Assessment of Cancer Therapy- General), and upper and lower body muscular endurance (bicep curl and sit-to-stand test) were also evaluated. Enrollment was feasible (n = 61 of 65 who expressed interest in the program), and retention (86.9%) and adherence (88% for exercise, 91% for discussion) were high; no adverse events were reported. Participants (mean age, 59.9 ± 10.1 yr; 96.2% female; 64.2% ovarian cancer, 28.3% breast cancer, 7.5% other cancer) reported they enjoyed the program (median, 7 of 7), and videoconferencing software was easy to use and had good video and audio quality (median, 5 of 5). From preprogram to postprogram, participants increased their weekly minutes of aerobic (mean (SD) change, 82.4 (144.2)) and resistance (mean (SD) change, 31.9 (42.7)) PA; sit-to-stand (mean (SD) change, 1.4 (3.9)) and bicep curl (mean (SD) change, 5.3 (6.8)) repetitions; and emotional (mean (SD) change, 0.82 (2.3) points), functional (mean (SD) change, 1.2 (3.6) points), and total QOL (mean (SD) change, 3 (7.9) points; all P < 0.05). A group-based PA program delivered using videoconference technology is feasible and acceptable for cancer survivors, and may increase PA and improve physical fitness and some aspects of QOL. A larger, controlled intervention is needed to determine efficacy, as well as pragmatic studies to directly compare this approach with conventional strategies (i.e., face-to-face programs).

Project description:BackgroundThe rise in internet addiction, including web-based gaming and social networking services, is a serious concern. Even with access to medical institutions and counseling services, individuals with internet addiction, particularly adolescents, often refuse medical treatment or counseling. Parent-focused psychological intervention may lead to positive outcomes by improving the parent-adolescent relationship and helping parents identify and modify their adolescent's problematic behaviors, including internet addiction.ObjectiveThis study was a pilot randomized controlled trial to test the feasibility of remote cognitive behavioral therapy via videoconferencing for parents of adolescents with internet addiction.MethodsA total of 13 parents of adolescents aged 12-20 years with internet addiction were recruited and randomly assigned to either 12 sessions of the videoconference-delivered cognitive behavioral therapy (vCBT) group (n=6, 46%) or the waitlist control group (n=7, 54%). The study period was from March 1, 2018, to March 31, 2022. The primary outcome was the scores of the Young Internet Addiction Test reported by the adolescents. The secondary outcomes were adolescents' hours of internet use per day (Internet Addiction Test), reported by the adolescents and by their parents; the Young Diagnostic Questionnaire, completed by the parents; and the quality of life of the adolescents and the parents, measured by the EQ-5D-5L. These were evaluated at weeks 0 and 13.ResultsAs the primary outcome, the mean total Internet Addiction Test score decreased from 67.7 (SD 18.3; 6/13, 46%) at week 0 to 56.2 (SD 25.1; 5/9, 56%) at week 13 in the vCBT group, compared to an increase from 66.9 (SD 21.9; 7/13, 54%) to 68.0 (SD 18.7; 4/9, 44%) in the control group. For all outcomes, no significant differences were found between the 2 groups (all P>.05).ConclusionsThis study suggested the practical feasibility of vCBT for parents of adolescents with internet addiction. Further large-scale, multicenter randomized controlled trials are necessary to examine the effectiveness.Trial registrationUMIN Clinical Trials Registry UMIN000032483; https://tinyurl.com/yuhen6c9.

Project description:BackgroundEndometriosis is a chronic disease characterized by growth of endometrial tissue outside the uterine cavity which could affect 200 million women (The term "woman" is used for convenience. Individuals gendered as man or as nonbinary can also suffer from this disease) worldwide. One of the most common symptoms of endometriosis is pelvic chronic pain associated with fatigue. This pain can cause psychological distress and interpersonal difficulties. As for several chronic diseases, adapted physical activity could help to manage the physical and psychological symptoms. The present study will investigate the effects of a videoconference-based adapted physical activity combined with endometriosis-based education program on quality of life, pain, fatigue, and other psychological symptoms and on physical activity.MethodsThis multicentric randomized-controlled trial will propose to 200 patients with endometriosis to be part of a trial which includes a 6-month program with 45 min to more than 120 min a week of adapted physical activity and/or 12 sessions of endometriosis-based education program. Effects of the program will be compared to a control group in which patients will be placed on a waiting list. All participants will be followed up 3 and 6 months after the intervention. None of the participants will be blind to the allocated trial arm. The primary outcome measure will be quality of life. Secondary outcomes will include endometriosis-related perceived pain, fatigue, physical activity, and also self-image, stereotypes, motivational variables, perceived support, kinesiophobia, basic psychological need related to physical activity, and physical activity barriers. General linear models and multilevel models will be performed. Predictor, moderator, and mediator variables will be investigated.DiscussionThis study is one of the first trials to test the effects of a combined adapted physical activity and education program for improving endometriosis symptoms and physical activity. The results will help to improve care for patients with endometriosis.Trial registrationClinicalTrials.gov, NCT05831735 . Date of registration: April 25, 2023.
