An Online Intuitive Eating Program for Pregnant Women With Obesity to Support Well-Being

2026年9月10日 更新者：Jennifer Green、San Diego State University

Feasibility and Preliminary Effects of an Online Intuitive Eating Intervention on Gestational Weight Gain and Well-Being in Pregnant Women

The goal of this feasibility randomized controlled trial is to assess the feasibility, acceptability, and demand, as well as preliminary effects of an evidence-based Intuitive Eating (IE) intervention among pregnant women who have obesity. The main research questions are:

RQ1: What is the feasibility (acceptability and demand) of implementing an Intuitive Eating Intervention among pregnant and postpartum women? RQ2: How does participation in the Pregnancy Intuitive Eating Intervention (PIE-I) impact key maternal health outcomes (i.e., gestational weight gain, intuitive eating behaviors, dietary quality, body image, and mental health) compared to a wait-list control?

Researchers will compare the Pregnancy Intuitive Eating Intervention (PIE-I) intervention group with the wait-list control to see what impact the PIE-I has on maternal well-being.

Participants randomized to the intervention group will complete the 8 week asynchronous IE intervention and have an opportunity to interview at the end of the study.

詳細な説明

This study is designed as a pilot feasibility trial with a target enrollment of 80 participants (40 per group; 1:1 randomization).

The purpose of this study is to evaluate the feasibility and preliminary effects of an evidence-based Intuitive Eating (IE) intervention, adapted from the Tribole and Resch framework, among pregnant individuals with obesity. Feasibility will be determined based on acceptability and demand scores. Acceptability will be assessed through satisfaction, perceived appropriateness, burden, and intent to continue use. Demand will be defined as retention and adherence to the intervention and participant engagement. Preliminary effects of the IE intervention will be explored in relation to the prevention of excessive gestational weight gain, intuitive eating behaviors, dietary quality, mental health, body image, and perceived stress.

実験的：Intuitive Eating Intervention Group

The (PIE-I) will be based on the IE Book & Workbook published by RDNs Evelyn Tribole & Elyse Resch. Each week, participants will be asked to watch 20 minute online modules and complete 1-2 workbook pages (workbook provided for free). Optional weekly office hours will be held by Certified Intuitive Eating Counselors.

Participants in the PIE-I will complete two online surveys - one at baseline (upon enrollment) and one after 8 weeks (the same surveys and time schedules as the intervention group). Each completed survey will earn participants an e-gift card as compensation for their time. Participants will also have an opportunity to complete a virtual interview at the end of the 8-week study.

Change from Baseline in Intuitive Eating Scale-3 (IES-3) Score at 8 Weeks
時間枠：Baseline and 8 weeks
Intuitive eating will be assessed using the Intuitive Eating Scale-3 (IES-3). The IES-3 assesses individuals' tendency to eat in response to physiological hunger and satiety cues rather than external or emotional cues. Higher scores indicate greater levels of intuitive eating. Change in IES-3 score from baseline to the 8-week post-intervention assessment will be compared between the intervention and wait-list control groups.
Baseline and 8 weeks
Change from Baseline Health Eating Index (HEI) Score at 8-weeks
時間枠：Baseline and 8 weeks
Diet quality will be assessed using the Healthy Eating Index (HEI), calculated from dietary intake data collected using the Automated Self-Administered 24-Hour (ASA24) Dietary Assessment Tool. The HEI assesses alignment with the Dietary Guidelines for Americans, with total scores ranging from 0 to 100. Higher scores indicate greater adherence to dietary recommendations and better overall diet quality.
Baseline and 8 weeks
Proportion of Participants Exceeding Recommended Gestational Weight Gain Guidelines
時間枠：From baseline through delivery
Gestational weight gain will be evaluated relative to recommended ranges based on pre-pregnancy body mass index (BMI) using Institute of Medicine (IOM) gestational weight gain guidelines. Excessive gestational weight gain (EGWG) will be defined as total gestational weight gain exceeding the recommended range for the participant's pre-pregnancy BMI category. The proportion of participants with EGWG will be compared between the intervention and wait-list control groups.
From baseline through delivery
Change from Baseline in Perceived Stress Scale (PSS) Score at 8 Weeks
時間枠：Baseline and 8 weeks
Perceived stress will be assessed using the Perceived Stress Scale (PSS-10), which measures the degree to which situations in one's life are perceived as stressful. The PSS-10 produces a total score ranging from 0 to 40. Higher scores indicate greater perceived stress. Change in PSS score from baseline to the 8-week post-intervention assessment will be compared between the intervention and wait-list control groups.
Baseline and 8 weeks
Change from Baseline in Edinburgh Postnatal Depression Scale, United States Version (EPDS-US) Score at 8 Weeks
時間枠：Baseline and 8 weeks
Depressive symptoms will be assessed using the Edinburgh Postnatal Depression Scale, United States version (EPDS-US). The EPDS is a self-report measure designed to assess symptoms of depression during the perinatal period. The 10-item scale produces a total score ranging from 0 to 30, with higher scores indicating greater depressive symptom severity. Change in EPDS-US score from baseline to the 8-week post-intervention assessment will be compared between the intervention and wait-list control groups.
Baseline and 8 weeks
Change from Baseline in Generalized Anxiety Disorder-7 (GAD-7) Score at 8 Weeks
時間枠：Baseline and 8 weeks
Anxiety symptoms will be assessed using the 7-item Generalized Anxiety Disorder scale (GAD-7). Each item is scored from 0 to 3, resulting in a total score ranging from 0 to 21. Higher scores indicate greater anxiety symptom severity. Change in GAD-7 score from baseline to the 8-week post-intervention assessment will be compared between the intervention and wait-list control groups.
Baseline and 8 weeks
Change from Baseline in Body Appreciation Scale-2 (BAS-2) Score at 8 Weeks
時間枠：Baseline and 8 weeks
Body appreciation will be assessed using the Body Appreciation Scale-2 (BAS-2), a 10-item measure assessing acceptance of, favorable opinions toward, and respect for one's body. Items are rated on a 5-point scale, and an overall score is calculated by averaging item responses, resulting in scores ranging from 1-5. Higher scores indicate greater body appreciation. Change in BAS-2 score from baseline to the 8-week post-intervention assessment will be compared between the intervention and wait-list control groups.
