Trial Summary

What is the purpose of this trial?

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.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop taking your current medications, but you cannot be using weight loss medications to participate.

What data supports the effectiveness of the HMZ 2.0 Intervention for Pregnancy Weight Management treatment?

The research on psychological strategies and cognitive-behavioral methods for pain management suggests that increasing perceived control and using cognitive coping skills can be beneficial. These elements, which are part of the HMZ 2.0 Intervention, may help manage weight during pregnancy by promoting healthier behaviors and improving self-management.¹ ² ³ ⁴ ⁵

Is the HMZ 2.0 Intervention for Pregnancy Weight Management safe for humans?

The studies reviewed focus on managing gestational weight gain through behavioral and educational interventions, which are generally considered safe for pregnant women. These interventions include providing information, motivational interviewing, and self-monitoring, all of which are non-invasive and have been associated with positive outcomes in managing weight gain during pregnancy.⁶ ⁷ ⁸ ⁹ ¹⁰

How does the HMZ 2.0 Intervention for Pregnancy Weight Management differ from other treatments?

The HMZ 2.0 Intervention is unique because it combines behavioral strategies with adaptive dosages to manage gestational weight gain, focusing on personalized education and counseling sessions. It also uses mHealth tools for daily monitoring, which helps tailor the intervention to individual needs, unlike standard treatments that may not offer such personalized and technology-driven approaches.⁶ ⁹ ¹¹ ¹² ¹³

Experimental Treatment

Active Control

Group I: HMZ 2.0 Intervention GroupExperimental Treatment1 Intervention

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).

Group II: Attention Control GroupActive Control1 Intervention

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.

Findings from Research

A pain self-management program combining Cognitive Behavioural Therapy (CBT) and physical exercise (PE) over 10 weeks showed significant improvements in pain experience, depression, anxiety, and overall health in 214 out of 311 participants.

The program effectively addressed complex pain by incorporating education, cognitive skills, exercise, and self-management strategies, demonstrating that multimodal approaches can enhance pain management outcomes.

A survey of 141 pregnant women revealed that a significant number did not receive essential advice on physical activity (37.5%), gestational weight gain (53.2%), and nutrition (66.2%), despite over 80% wanting this information.

Women with pre-pregnancy overweight or excessive gestational weight gain were less likely to receive counseling, indicating a need for health professionals to improve communication and support for these individuals.

Interventions aimed at limiting gestational weight gain (GWG) were found to be equally effective whether they were based on behavior change theories or not, with 19 studies analyzed in this review.

Key strategies for effective GWG interventions included providing information, motivational interviewing, behavioral self-monitoring, and offering rewards for successful behavior, suggesting that combining these techniques with dietary changes may enhance effectiveness.

In a study of 24 pregnant women with overweight or obesity, those who experienced more than one nighttime awakening per week engaged in significantly less physical activity, burning 167.56 fewer calories compared to those with fewer awakenings.

Each additional weekly nighttime awakening was associated with a 0.76-pound increase in gestational weight gain, highlighting the importance of sleep quality in managing weight during pregnancy.
