Assessing Whether Meditation Improves Quality of Life for Adolescent Girls With Polycystic Ovary Syndrome: Protocol for a Randomized Controlled Trial.

BACKGROUND: Polycystic Ovary Syndrome (PCOS) is a common endocrine condition characterized by irregular periods and hyperandrogenism. Adolescents with PCOS have impaired quality of life (QOL) and increased psychological distress. Transcendental Meditation (TM) is a well-established self-management strategy that has been used to improve stress and well-being. A meta-analysis of TM trials has shown beneficial effects on stress and blood pressure in adults. Recent data are suggesting that another self-management strategy called a mindfulness stress management program has a role in improving QOL in women with PCOS, but there are no studies in adolescents. OBJECTIVE: This study aims to evaluate the effect of TM on QOL and psychological distress in adolescent girls with PCOS. METHODS: This study is a randomized controlled trial that will be conducted over eight weeks at the Women's and Children's Hospital in Adelaide, South Australia, to determine the effect of TM on QOL and psychological distress in adolescent girls (aged 12-20 years) with PCOS. A total of 40 girls will be randomized into either the TM (n=20) or control group (n=20). The TM group will be asked to practice TM in a comfortable sitting position with the eyes closed, for 15 minutes twice daily over eight weeks. The control group will be asked to sit quietly for 15 minutes twice daily for eight weeks. The primary outcomes are any effects on improving QOL and psychological distress, and the secondary outcomes are any effects on lowering blood pressure and salivary cortisol levels. RESULTS: The recruitment of study participants began in May 2019 and is expected to be completed by June 2020. It is expected that the adolescent girls with PCOS practicing TM over eight weeks will have a significant improvement in QOL and psychological distress compared to adolescents in the control group. Also, it is expected that adolescent girls in the TM group will have lower salivary cortisol levels and lower blood pressure. CONCLUSIONS: This study will be the first to evaluate the effect of TM on QOL in adolescent girls with PCOS. The study will provide valuable information on a potential self-management strategy to improve QOL and well-being in adolescent girls with PCOS.

The empirical status of the third-wave behaviour therapies for the treatment of eating disorders: A systematic review.

Although third-wave behaviour therapies are being increasingly used for the treatment of eating disorders, their efficacy is largely unknown. This systematic review and meta-analysis aimed to examine the empirical status of these therapies. Twenty-seven studies met full inclusion criteria. Only 13 randomized controlled trials (RCT) were identified, most on binge eating disorder (BED). Pooled within- (pre-post change) and between-groups effect sizes were calculated for the meta-analysis. Large pre-post symptom improvements were observed for all third-wave treatments, including dialectical behaviour therapy (DBT), schema therapy (ST), acceptance and commitment therapy (ACT), mindfulness-based interventions (MBI), and compassion-focused therapy (CFT). Third-wave therapies were not superior to active comparisons generally, or to cognitive-behaviour therapy (CBT) in RCTs. Based on our qualitative synthesis, none of the third-wave therapies meet established criteria for an empirically supported treatment for particular eating disorder subgroups. Until further RCTs demonstrate the efficacy of third-wave therapies for particular eating disorder subgroups, the available data suggest that CBT should retain its status as the recommended treatment approach for bulimia nervosa (BN) and BED, and the front running treatment for anorexia nervosa (AN) in adults, with interpersonal psychotherapy (IPT) considered a strong empirically-supported alternative.

Mindfulness-based interventions for adults who are overweight or obese: a meta-analysis of physical and psychological health outcomes.

OBJECTIVE: The aim of this study was to evaluate the impact of mindfulness-based interventions on psychological and physical health outcomes in adults who are overweight or obese. METHODS: We searched 14 electronic databases for randomized controlled trials and prospective cohort studies that met eligibility criteria. Comprehensive Meta-analysis software was used to compute the effect size estimate Hedge's g. RESULTS: Fifteen studies measuring post-treatment outcomes of mindfulness-based interventions in 560 individuals were identified. The average weight loss was 4.2 kg. Overall effects were large for improving eating behaviours (g = 1.08), medium for depression (g = 0.64), anxiety (g = 0.62) and eating attitudes (g = 0.57) and small for body mass index (BMI; g = 0.47) and metacognition (g = 0.38) outcomes. Therapeutic effects for BMI (g = 0.43), anxiety (g = 0.53), eating attitudes (g = 0.48) and eating behaviours (g = 0.53) remained significant when examining results from higher quality randomized control trials alone. There was no efficacy advantage for studies exceeding the median dose of 12 h of face-to-face intervention. Studies utilizing an Acceptance and Commitment Therapy approach provided the only significant effect for improving BMI (g = 0.66), while mindfulness approaches produced great variation from small to large (g = 0.30-1.68) effects across a range of psychological health and eating-related constructs. Finally, the limited longitudinal data suggested maintenance of BMI (g = 0.85) and eating attitudes (g = 0.75) gains at follow-up were only detectable in lower quality prospective cohort studies. CONCLUSIONS: Mindfulness-based interventions may be both physically and psychologically beneficial for adults who are overweight or obese, but further high-quality research examining the mechanisms of action are encouraged.

The Effect of Weight Loss on Indigenous Australians with Diabetes: a study of Feasibility, Acceptability and Effectiveness of Laparoscopic Adjustable Gastric Banding.

BACKGROUND/OBJECTIVES: Diabetes and obesity are common and serious health challenges for indigenous people worldwide. The feasibility of achieving substantial weight loss, leading to remission of diabetes, was evaluated in a regional indigenous Australian community. SUBJECTS/METHODS: A prospective cohort study of 30 obese indigenous adults from the Rumbalara Aboriginal Co-operative in Central Victoria was performed. Inclusion criteria included aboriginality, BMI > 30 kg/m(2) and diabetes diagnosed within the last 10 years. Weight loss was achieved using laparoscopic adjustable gastric banding (LAGB). Participants were treated in their community and followed for 2 years. Outcomes were compared with those of non-indigenous Australians from an earlier randomized controlled trial (RCT) using a similar protocol. RESULTS: 30 participants (26 females, mean age 44.6 years; mean BMI 44.3) had LAGB at the regional hospital. Twenty-six participants completed diabetes assessment at 2 years follow-up. They showed diabetes remission (fasting blood glucose < 7.0 mmol/L and haemoglobin A1c (HbA1c) < 6.2 % while off all therapy except metformin) in 20 of the 26 and a mean weight loss (SD) of 26.0 (14) kilograms. Based on intention-to-treat, remission rate was 66 %. Quality of life improved. There was one early event and 12 late adverse events. The outcomes for weight loss and diabetes remission were not different from the LAGB group of the RCT. CONCLUSIONS: For obese indigenous people with diabetes, a regionalized model of care centred on the LAGB is an effective approach to a serious health problem. The model proved feasible and acceptable to the indigenous people. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ACTRN 12609000319279).

Physiological and behavioural outcomes of a randomised controlled trial of a cognitive behavioural lifestyle intervention for overweight and obese adolescents.

AIM: This study evaluates the efficacy of the Choose Health program, a family-based cognitive behavioural lifestyle program targeting improved eating and activity habits, in improving body composition, cardiovascular fitness, eating and activity behaviours in overweight and obese adolescents. METHOD: The sample comprised 29 male and 34 female overweight (n = 15) or obese (n = 48) adolescents aged 11.5-18.9 years (M = 14.3, SD = 1.9). Participants were randomly allocated to treatment or waitlist control conditions; waitlist condition participants were offered treatment after 6 months. DEXA-derived and anthropometric measures of body composition; laboratory-based cycle ergometer and field-assessed cardiovascular fitness data; objective and self-report physical activity measures; and self-report measures of eating habits and 7-day weighed food diaries were used to assess treatment outcome. Adherence to treatment protocols was high. RESULTS: Treatment resulted in significant (p < .05) and sustained improvements in a range of body composition (body fat, percent body fat, lean mass) and anthropometric measures (weight, BMI, BMI-for-age z-score and percentiles). Minimal improvements were seen in cardiovascular fitness. Similar results were obtained in completer and intention-to-treat analysis. Poor adherence to assessment protocols limits conclusions that can be drawn from physical activity and dietary data. CONCLUSIONS: Participation in the Choose Health program resulted in significant improvement in body composition. Longer-term follow up is required to determine the durability of intervention effects. Alternative approaches to the measurement of diet and physical activity may be required for adolescents.
