Healthy Mom Zone Gestational Weight Gain Management Intervention 2.0

Purpose

The goal of this clinical trial is to see if the enhanced HMZ 2.0 intervention with new control system/digital platform to regulate gestational weight gain (GWG) and impact maternal-infant outcomes while collecting implementation data works and can be given to other pregnant women in various settings. The question this study aims to answer are: 1. Does the new intervention manage GWG? 2. Does the new intervention have any influence on sleep and eating behaviors and infant outcomes. 3. Does the new platform and other data collected help inform how well the research and information can be used in health care settings? 144 pregnant women with overweight/obesity will be randomized to either the HMZ 2.0 intervention or attention control groups from ~8-36 weeks gestation. All participants will be asked to: 1. Weight themselves and wear an activity monitor each day over the study. 2. Complete online surveys at either a weekly or monthly level about their thoughts, attitudes, and behaviors on GWG, physical activity, eating behaviors, sleep, their anxiety, depression, and stress. 3. Attend weekly sessions with a registered dietician. The weekly sessions will differ based on intervention group. The HMZ 2.0 intervention group will receive education, create and follow goal-setting and action plans, self-monitor their behaviors, and receive feature evidence and fetal growth facts. Education, goals, and self-monitoring will focus on GWG, physical activity, eating behaviors, sleep, self-regulating behaviors and emotions, and preparing for labor/delivery and postpartum. The attention control group will receive weekly sessions on preparing for labor/delivery and benefits of behavioral pain management strategies (e.g., mindfulness-based relaxation, imagery, music, massage, deep-breathing) to help with pain after childbirth without medicine.

Intervention Model Description
A staff member will request randomization after the pre-intervention measures by unique subject ID number. The study biostatistician will develop the randomization scheme using variable-size, random permuted blocks to ensure the number of subjects in each group is balanced after each set of B randomized subjects where B is block size. Randomization to control (n=72) and intervention (n=72) groups will use 1:1 allocation; subjects will be entered consecutively. Randomization will be stratified by pre-pregnancy BMI status (< 29.9 kg/m2 vs. greater than or equal to 30 kg/m2). A staff member will call each woman to inform her of study assignment and schedule her for the first session (attention control or HMZ 2.0 intervention).

Masking Description
All investigators and the outcomes assessor(s) will be masked from the randomization scheme, and what study groups each participant will be/was randomized to. The randomization scheme will be developed and programmed into REDCap by the biostatistician. The team of investigators will not have knowledge of the randomization scheme or be able to view the programming. The programming will be password protected and only be able to be accessed by the biostatistician.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
HMZ 2.0 Intervention Group
HMZ 2.0 will be delivered by a registered dietitian in weekly didactic, one-on-one discussions in remote synchronous format (e.g., Zoom). If a subject has internet connectivity issues, she will be able to participate in the remote sessions from an onsite location (e.g., laboratory space on the Penn State University Park campus, clinical space at Hershey campus or Geisinger). All intervention women will receive the baseline intervention delivered as a maximum of 24 weekly modules (depending on gestational age at enrollment) which includes: Education and Counseling (GWG/PA/EI/sedentary behaviors/sleep behaviors/stress management, etc.), Goal-Setting and Action Plans (guided and self-selected PA/EI goals including recipe and workout booklet use), Self-Monitoring (wearing/using mHealth tools to monitor GWG/PA/EI/sleep), and Featured Evidence and Fetal Growth Facts (evidence-based studies and baby growth fun facts shared with women about how mom's health impacts her baby).
  • Behavioral: HMZ 2.0 Intervention
    The intervention may be adapted such that a woman receives more support with each adaptation (only women who need added support to regulate GWG will receive adaptation). The model-based predictive control system in the HMZ 2.0 digital platform will continually and automatically evaluate GWG, identify when a woman may exceed GWG guidelines, and recommend an adaptation. The registered dietitian will review the data and behavior strategies that are suggested (guided PA workouts, EI cooking demonstrations, customized grocery planning, portion size control, food scales, and meal replacements). Practical, easy-to-adopt examples will be provided (walking in 5-10 min increments throughout the day to increase PA kcal, reduce sitting by 5 min/hour; replace 8 oz of whole milk with skim milk to reduce EI kcal) to facilitate behavior change while adhering to safety standards. Each woman's unique preferences and past successes with strategies are also considered when personalizing the dosage.
Active Comparator
Attention Control Group
All women will receive prenatal care offered by recruitment sites with routine provider visits, prenatal counseling, brief discussions on healthy prenatal behaviors, and clinical oversight of health (e.g., monitor glucose levels if diagnosed with gestational diabetes during the study period). Women randomized to the attention control group will complete the same measurement procedures as the intervention group. To match the HMZ intervention group, women will receive weekly, remote-delivered education content (60 min/session) on preparing for labor/delivery and benefits of behavioral pain management strategies (e.g., mindfulness-based relaxation, imagery, music, massage, deep-breathing) to regulate pain after childbirth with non-pharmacological approaches. Content is drawn from evidence-based guidelines and materials designed by Dr. Downs and her team for a Patient-Provider Toolbox to reduce opioid-related pain management use after childbirth.
  • Behavioral: Attention Control Intervention
    Consistent with guidelines for comparator groups, all women will receive prenatal care offered by recruitment sites with routine provider visits, counseling about prenatal behaviors (e.g., no smoking), and clinical oversight of health. Women randomized to the attention control group will complete the same measurement procedures as the intervention group.

Detailed Description

Pre-intervention: Onsite procedures. Pregnant women with overweight/obesity enrolled in the study will be asked to complete assessments (≥8 and <18 weeks gestation) at the Penn State Clinical Research Center (University Park or Hershey campus) or at home via Zoom. A study staff member will describe the study and obtain consent. Women with any health issues will be asked to follow-up with their provider and/or given a referral as needed. Subjects will have access to REDCap (Research Electronic Data Capture), a secure, web-based application to complete online surveys for social cognitive outcomes for PA and EI (eating healthy/ limiting unhealthy foods), and sleep and eating behaviors. A staff member will answer questions and explain the free-living procedures. This visit will take ~90 minutes. Pre-intervention: Free-living procedures. A 10-day period will provide a grounding of each subject's baseline physical activity (including sedentary behavior), energy intake, social cognitive determinants, and sleep/eating behaviors for the individual energy balance model to predict GWG. Energy intake kcal will be estimated with the back-calculation method utilizing measured weight, physical activity, and resting metabolic rate (quadratic regression formula). There is not a set threshold of data compliance for back-calculating energy intake, the investigators will use strategies to reach similar compliance (>90%) as our feasibility trial and other studies that used a run-in phase. Only women with no weight or physical activity data during this period will be excluded. On the morning of each day of the 10-day free-living protocol, subjects will be asked to complete study measures. The investigators will prompt with daily reminders and follow-up with non-compliant women to resolve barriers/technology issues. Measurement procedures over study period. Subjects will use mHealth tools for real-time data collection on our energy balance and behavior model constructs to predict GWG in the Control Optimization Trial and assess sleep/eating behaviors. Data collection will occur: daily for GWG and physical activity/sedentary behavior/sleep; weekly for physical activity/energy intake social cognitive determinants (online in REDCap), and on at least 2 weekdays/1 weekend for energy intake diet quality. Monthly measures of eating behaviors and psychosocial health will be assessed. Post-intervention assessments. Maternal GWG, physical activity, sedentary behavior, energy intake, social cognitive determinants, and sleep/eating behaviors will be obtained with the same mHealth devices/procedures as described above in the pre-intervention assessments. To reduce subject burden, there will be no onsite post-assessments. Labor and delivery data will be abstracted from the medical record with patient HIPAA authorization. Randomization. A staff member will request randomization after the pre-intervention measures by unique subject ID number. The study biostatistician, will develop the randomization scheme using variable-size, random permuted blocks to ensure number of subjects in each group is balanced after each set of B randomized subjects where B is block size. Randomization to control (n=72) and intervention (n=72) groups will use 1:1 allocation; subjects will be entered consecutively. Randomization will be stratified by pre-pregnancy BMI status (< 29.9 kg/m2 vs. ≥ 30 kg/m2). A staff member will call each woman to inform her of study assignment and schedule her for the first session (attention control or HMZ 2.0 intervention).
