Feasibility/acceptability of an acceptance-based therapy intervention for diverse adolescent girls with overweight/obesity

Evaluating an acceptance-based lifestyle modification program to address cardiovascular disease risk among adolescent girls with overweight and obesity: Protocol for a randomized controlled trial

BACKGROUND

Behavioral weight loss interventions achieve only limited weight loss in adolescent samples and weight regain is common. This limited intervention success may be attributed, in part, to adolescents' lack of self-regulation skills essential for lifestyle modification and use of a one-size fits-all approach to produce weight loss in boys and girls. Interventions which teach self-regulation skills, such as Acceptance-Based Therapy (ABT), and are tailored to meet gender-specific concerns, are critical to help adolescents adapt to pervasive biological and environmental influences toward weight gain.

OBJECTIVE

This trial tests the effect of an ABT intervention on cardiometabolic health, health-related behaviors, and psychological factors among adolescent girls with overweight or obesity (OW/OB).

METHODS

Girls 14-19 years (N = 148; ≥ 40% racial/ethnic minorities) with OW/OB (BMI: ≥ 85th percentile) will be enrolled in the study. Participants will be randomized to one of two 6-month interventions, consisting of either 18 sessions of ABT or 9 sessions of a health education control, an augmented version of standard care for adolescent OW/OB, both led by bachelor's level interventionists.

RESULTS

Recruitment is taking place in Philadelphia, USA, from January 2024 to January 2028. Cardiometabolic health markers (adiposity; blood pressure; blood lipids), health-related behaviors (dietary intake; physical activity; sleep), and psychological factors (quality of life; depression; disordered eating; psychological flexibility) will be measured at baseline, mid-treatment, post-treatment, 6-month follow-up, and 12-month follow-up.

CONCLUSIONS

This study will provide valuable information on a novel intervention tailored to the needs of adolescent girls with OW/OB to address self-regulation and cardiometabolic health.

Wellness Achieved Through Changing Habits: A Randomized Controlled Trial of an Acceptance-Based Intervention for Adolescent Girls With Overweight or Obesity

Background: Obesity prevalence among adolescent girls continues to rise. Acceptance-based therapy (ABT) is effective for weight loss in adults and feasible and acceptable for weight loss among adolescents. This pilot randomized controlled trial (RCT) assessed effectiveness of an adolescent-tailored ABT intervention on decreasing weight-related outcomes and improving psychological outcomes compared with enhanced care. Methods: In this 6-month, two-arm pilot RCT, participants were randomized to the ABT intervention or to enhanced care. The ABT intervention condition attended 15 virtual, 90-minute group sessions. The enhanced care comparison received 15 healthy lifestyle handouts and virtually met twice with a registered dietitian. The primary outcome assessed was change in BMI expressed as a percentage of the 95th percentile (%BMIp95). Results: Participants included 40 girls (ages 14-19) assigned to ABT (n = 20) or enhanced care (n = 20). A decrease in %BMIp95 was observed within the ABT intervention [d = -0.19, 95% confidence interval, CI: (-0.36 to -0.02)], however, not within the enhanced care comparison [d = -0.01, 95% CI: (-0.09 to 0.07)]. The ABT group showed slight changes in psychological flexibility [d = -0.34, 95% CI: (-0.62 to -0.06)] over enhanced care [d = -0.11, 95% CI: (-0.58 to 0.37)]. There was no significant intervention effect noted between groups. Conclusion: In this pilot RCT, the ABT intervention was as effective as enhanced care for weight loss. However, previous ABT studies occurred in person, and this study was conducted virtually due to COVID-19. Thus, future research investigating the potential effectiveness of ABT in-person among adolescents and optimization of virtual interventions is needed.

Integrating COM-B and the person-based approach to develop an ACT based therapy programme to raise self-determination in adolescents with obesity

BACKGROUND

This paper details the development of the Adolescent Intrinsic Motivation 'AIM2Change' intervention to support weight-management in young people previously unable to make changes whilst attending a tier 3 weight management service for children and young people. AIM2Change is an acceptance and commitment therapy based intervention that will be delivered one-to-one online over a seven-week period.

METHODS

To develop this intervention, we have triangulated results from a qualitative research study, patient and public involvement groups (PPI) and a COM-B (capability, opportunity, motivation, behaviour) analysis, in a method informed by the person-based approach.

RESULTS

The integrated development approach yielded a broad range of perspectives and facilitated the creation of a tailored intervention to meet the needs of the patient group whist remaining pragmatic and deliverable.

CONCLUSIONS

The next steps for this intervention will be in-depth co-development of the therapy sessions with service users, before implementing a proof of concept trial.

Obesity in children and adolescents: epidemiology, causes, assessment, and management

This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.
