About this study

Official title: Effects of Body-Based and Mind-Based Regulation Approaches on Heart Rate Variability, Emotional Eating, and Psychological Indicators in Overweight and Obese Women: An Evaluator-Blinded Randomized Trial

This study will compare two regulation-based approaches in women with overweight or obesity. The first approach is a body-based regulation program including breathing awareness, body-awareness-based yoga practices, non-invasive manual auricular stimulation, and restorative relaxation. The second approach is a mind-based regulation program including structured psychoeducation and cognitive-emotional awareness activities focused on stress, emotions, automatic thoughts, and emotional eating.

Participants will be women aged 18 to 60 years with a body mass index between 27.0 and 39.9 kg/m². Eligible participants will be randomly assigned to one of the two intervention groups. Both programs will last 8 weeks.

The main aim of the study is to examine and compare the preliminary effects of these two approaches on heart rate variability, especially RMSSD, which is an indicator of cardiac vagal regulation. The study will also assess emotional eating, self-compassion, mindfulness, body measurements, body composition, adherence to the program, and possible adverse events. Assessments will be performed at baseline and after the 8-week intervention by an evaluator who is blinded to group allocation.

Read the detailed description

Overweight and obesity are associated not only with metabolic and physical health problems but also with changes in autonomic nervous system regulation, emotional eating, and psychological well-being. Reduced heart rate variability may reflect impaired cardiac vagal regulation and may be related to stress-related and emotion-related eating behaviors. Regulation-based approaches that target either body-to-mind or mind-to-body pathways may provide supportive strategies for improving autonomic and emotional regulation in women with overweight or obesity.

This study is designed as a two-arm, parallel-group, evaluator-blinded randomized trial. The study population will consist of women aged 18 to 60 years with overweight or obesity who apply to the Exercise and Obesity Unit of the Faculty of Physiotherapy and Rehabilitation, Pamukkale University. Participants will be randomized in a 1:1 ratio using BMI-category-stratified block randomization based on a computer-generated allocation sequence prepared by a researcher who is not involved in outcome assessment or intervention delivery. Allocation will be concealed until the baseline assessment is completed. The evaluator who performs baseline and post-intervention assessments will remain blinded to group allocation.

The Body-Based Regulation Group will receive an 8-week structured program delivered face-to-face by a physiotherapist. The program will include breathing awareness, body-awareness-based yoga practices, non-invasive manual auricular stimulation, and restorative relaxation. Sessions will be conducted twice weekly for 8 weeks, with each session lasting approximately 60 minutes. This intervention is intended to support autonomic and cardiac vagal regulation through body-based mechanisms.

The Mind-Based Regulation Group will receive an 8-week structured psychoeducation and cognitive-emotional awareness program. The program will focus on recognizing the relationships among stress, emotional states, automatic thoughts, and eating behavior; identifying triggers for emotional eating; developing more balanced cognitive responses; and creating alternative behavioral strategies for eating urges. Face-to-face structured sessions will be conducted in weeks 1, 4, and 8. In the remaining weeks, participants will receive standardized digital content and study forms and will attend short online meetings. The weekly module duration will be approximately 30 to 45 minutes. This intervention will not include yoga, breathing exercises, relaxation exercises, or other body-based practices.

Assessments will be conducted at baseline and after the 8-week intervention. Heart rate variability will be the primary physiological outcome. RR interval data will be recorded using a Polar H10 chest strap after a 10-minute quiet adaptation period, followed by a 5-minute resting recording. RMSSD will be the primary HRV parameter. If required according to distributional characteristics, RMSSD values will be analyzed after natural logarithmic transformation as lnRMSSD. Secondary HRV parameters will include HF, LF/HF, SDNN, and mean heart rate.

Patient-reported outcomes will include emotional eating, eating behavior, self-compassion, and mindfulness. Anthropometric measurements and body composition will be recorded as exploratory and descriptive outcomes. Adherence to the intervention, completion of home/module-related activities, and possible adverse events will also be monitored throughout the study.

The primary analysis will compare post-intervention RMSSD or lnRMSSD values between groups using an analysis of covariance model adjusted for baseline values. Secondary outcomes will be analyzed using similar baseline-adjusted models where appropriate. The study is planned to include 30 participants in total, with 15 participants in each group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Body-Based Regulation ProgramBehavioural

    Participants will receive an 8-week structured body-based regulation program administered by a physiotherapist. The program consists of 16 supervised face-to-face sessions (twice weekly, 60 minutes each) including breathing awareness exercises, body awareness-based yoga practices, non-invasive manual auricular stimulation, and restorative relaxation techniques. The intervention is designed to improve body awareness, autonomic nervous system regulation, and emotional regulation.

  • Mind-Based Regulation ProgramBehavioural

    Participants will receive an 8-week structured psychoeducation and cognitive-emotional awareness program developed by a clinical psychologist. The intervention aims to improve awareness of the relationships among stress, emotions, automatic thoughts, and eating behavior, recognize emotional eating triggers, develop balanced cognitive responses, and strengthen adaptive coping strategies. The program includes face-to-face sessions during weeks 1, 4, and 8, standardized digital educational materials, weekly online follow-up meetings, and self-monitoring exercises. No yoga, breathing exercises, relaxation exercises, or body-based practices are included.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Heart Rate Variability (RMSSD)

    RMSSD (ms) will be derived from a 5-minute resting RR-interval recording obtained using a Polar H10 chest strap and analyzed using Kubios HRV software. If required based on distributional characteristics, RMSSD values will be natural-log transformed and analyzed as lnRMSSD.

    Measured: Baseline and Week 8

Secondary outcomes (10)
  1. High-Frequency Power (HF)

    Change in high-frequency (HF) power (ms²), an index of parasympathetic cardiac autonomic activity derived from heart rate variability recordings.

    Measured: Baseline and Week 8

  2. Low Frequency/High Frequency Ratio (LF/HF Ratio)

    Change in the low frequency/high frequency (LF/HF) ratio derived from heart rate variability recordings.

    Measured: Baseline and Week 8

  3. Standard Deviation of NN Intervals (SDNN)

    Change in the standard deviation of normal-to-normal intervals (SDNN, ms), a time-domain heart rate variability parameter reflecting overall autonomic variability.

    Measured: Baseline and Week 8

  4. Mean Heart Rate

    Change in resting mean heart rate (beats per minute [bpm]) measured during the heart rate variability assessment.

    Measured: Baseline and Week 8

  5. Eating Behavior (Dutch Eating Behavior Questionnaire, DEBQ)

    Eating behavior will be assessed using the validated Turkish version of the 33-item Dutch Eating Behavior Questionnaire (DEBQ). The questionnaire comprises three subscales assessing emotional eating, external eating, and restrained eating. Items are rated on a 5-point Likert scale ranging from "never" to "very often," with an additional "not applicable" response option where appropriate. Scores for the emotional eating, external eating, and restrained eating subscales will be calculated and analyzed separately according to the validated scoring instructions. Higher scores on each subscale indicate a greater tendency toward the corresponding eating behavior.

    Measured: Baseline and Week 8

  6. Emotional Eating (Turkish Emotional Eating Scale)

    Emotional eating will be assessed using the 30-item Turkish Emotional Eating Scale. Each item is rated on a 5-point Likert scale ranging from 1 ("never") to 5 ("almost always"). The scale evaluates the tendency to eat in response to emotional states and related difficulties in controlling eating behavior. A total score is calculated by summing the item scores, with possible scores ranging from 30 to 150. Higher scores indicate a greater tendency toward emotional eating.

    Measured: Baseline and Week 8

  7. Self-Compassion

    Self-compassion will be assessed using the validated Turkish version of the 24-item Self-Compassion Scale. The scale evaluates how individuals respond to themselves during difficult or distressing experiences. Items are rated on a 5-point Likert scale ranging from "almost never" to "almost always." Negatively worded items will be reverse-scored according to the validated scoring instructions. A total score will be calculated, with higher scores indicating greater self-compassion.

    Measured: Baseline and Week 8

  8. Mindfulness

    Mindfulness will be assessed using the validated Turkish version of the 15-item Mindful Attention Awareness Scale (MAAS). The scale evaluates an individual's general tendency to attend to and remain aware of present-moment experiences in daily life. Items are rated on a 6-point Likert scale ranging from "almost always" to "almost never." A single overall score will be calculated according to the validated scoring instructions. Higher scores indicate greater mindful awareness.

    Measured: Baseline and Week 8

  9. Protocol Adherence

    The percentage of prescribed intervention components completed will be recorded. In the Body-Based Regulation Group, adherence will be calculated based on attendance at the 16 supervised face-to-face sessions. In the Mind-Based Regulation Group, adherence will be calculated based on completion of weekly modules, digital content, brief online meetings, and study forms. Participants completing at least 80% of the prescribed intervention components will be classified as protocol completers.

    Measured: Through Week 8

  10. Participants With Intervention-Related Adverse Events

    The number and type of symptoms, unexpected health problems, and adverse events occurring during or after the interventions and considered possibly related to the intervention will be recorded.

    Measured: Through Week 8
