“…We had previously reasoned that delivering a GI intervention through the use of council, with an important theoretical underpinning based on SDT, could provide a culturally sensitive and developmentally appropriate space from which to shift to healthy lifestyle behaviors. 39 SDT posits that healthy development involves integrating autonomy (inner organization and self-regulation) with connectedness (integration of oneself with others). 48 This approach to human motivation posits that there are 3 innate human psychological needs that form the basis for optimal self-motivation: competence, relatedness, and autonomy.…”

“…Salivary cortisol diurnal pattern was assessed before and after the 6-week intervention. As previously detailed, 39 saliva was collected for both pre- and posttest at home on 3 separate days at 3 timepoints: awakening, 30-minutes postawakening (+30), and in the evening. Average cortisol awakening response (CAR) was calculated by averaging the differences between cortisol level upon awakening and 30-minutes postawakening across the 3 days, and diurnal cortisol slope (DCS) was calculated by averaging the differences between cortisol levels from awakening to evening.…”

“…40 The council process as we used it has been fully described previously. 39 All GIC sessions in this pilot were cofacilitated by authors MJW and JP. Briefly, the essential conduct of council consists of the following processes: All participants sit in a circle, minimizing hierarchy between facilitators and students. A designated object (the “talking piece”) is used to focus the communication and identify the speaker.…”

“…The full protocol of this clinical trial has been previously described. 39 As part of the development phase for this intervention, we conducted a preliminary 6-week pilot trial of the major intervention components to test for the feasibility, acceptability, and early signs of efficacy of new aspects of the intervention that were different from our prior work. The primary objective of this article is therefore to more fully describe the qualitative and quantitative outcomes from this 6-week pilot intervention that informed the subsequent development of the final RCT intervention.…”

Background The combination of higher stress and higher obesity rates suggests that Latino youth in the United States may be a population at particular risk for obesity-related adverse health outcomes. The objective of this article is to describe the feasibility, acceptability, and quantitative stress-related outcomes of a 6-week pilot lifestyle intervention using guided imagery (GI) council in order to reduce risk factors for obesity-related disease. Methods Seventeen urban, adolescents (12 females/5 males, 16 Latino, age 17 ± 1 years, grades 9–12, body mass index 22 ± 4) participated in the 6-week, after-school pilot intervention. The intervention consisted of three, 75-minute after-school sessions delivered weekly for 6 weeks. The 3 weekly sessions included 1 session each of nutrition education, physical activity education and practice, and GI delivered in council, a facilitated group process based on indigenous practices. Feasibility and acceptability were assessed by attendance and qualitative exit interview. Stress outcomes included salivary cortisol and perceived stress. Results The pilot intervention was found to be feasible to deliver in an after-school setting. The GI and council group format were well liked. A 31% reduction in salivary cortisol was observed following the stress-reduction GI sessions. Diurnal cortisol patterns did not change across the intervention, but change in perceived stress was correlated with change in cortisol awakening response. Conclusions The intervention was feasible to deliver and highly acceptable. Acute reduction in salivary cortisol was seen following group GI, while no change was seen in daily cortisol patterns. These results support the development of a full 12-week intervention using GI council to reduce obesity-related disease risk.

Background Prevention of obesity in adolescents is an international public health priority. The prevalence of overweight and obesity is over 25% in North and South America, Australia, most of Europe, and the Gulf region. Interventions that aim to prevent obesity involve strategies that promote healthy diets or ‘activity’ levels (physical activity, sedentary behaviour and/or sleep) or both, and work by reducing energy intake and/or increasing energy expenditure, respectively. There is uncertainty over which approaches are more effective, and numerous new studies have been published over the last five years since the previous version of this Cochrane Review. Objectives To assess the effects of interventions that aim to prevent obesity in adolescents by modifying dietary intake or ‘activity’ levels, or a combination of both, on changes in BMI, zBMI score and serious adverse events. Search methods We used standard, extensive Cochrane search methods. The latest search date was February 2023. Selection criteria Randomised controlled trials in adolescents (mean age 12 years and above but less than 19 years), comparing diet or 'activity' interventions (or both) to prevent obesity with no intervention, usual care, or with another eligible intervention, in any setting. Studies had to measure outcomes at a minimum of 12 weeks post baseline. We excluded interventions designed primarily to improve sporting performance. Data collection and analysis We used standard Cochrane methods. Our outcomes were BMI, zBMI score and serious adverse events, assessed at short‐ (12 weeks to < 9 months from baseline), medium‐ (9 months to < 15 months) and long‐term (≥ 15 months) follow‐up. We used GRADE to assess the certainty of the evidence for each outcome. Main results This review includes 74 studies (83,407 participants); 54 studies (46,358 participants) were included in meta‐analyses. Sixty studies were based in high‐income countries. The main setting for intervention delivery was schools (57 studies), followed by home (nine studies), the community (five studies) and a primary care setting (three studies). Fifty‐one interventions were implemented for less than nine months; the shortest was conducted over one visit and the longest over 28 months. Sixty‐two studies declared non‐industry funding; five were funded in part by industry. Dietary interventions versus control The evidence is very uncertain about the effects of dietary interventions on body mass index (BMI) at short‐term follow‐up (mean difference (MD) ‐0.18, 95% confidence interval (CI) ‐0.41 to 0.06; 3 studies, 605 participants), medium‐term follow‐up (MD ‐0.65, 95% CI ‐1.18 to ‐0.11; 3 studies, 900 participants), and standardised BMI (zBMI) at long‐term follow‐up (MD ‐0.14, 95% CI ‐0.38 to 0.10; 2 studies, 1089 participants); all very low‐certainty evidence.
