My Baby My Move A Community Wellness Intervention

My Baby, My Move+ (2019-2021) is a peer-led wellness intervention which aims to reduce excessive gestational weight gain (EGWG) by targeting prenatal physical activity, mood, and sleep quality. Up to 50% of pregnant women in the U.S. gain weight in excess of the Institute of Medicine guidelines. EGWG leads to poor maternal and child outcomes. It also sets the stage for long-term overweight/obesity for both mother and child. The MBMM+ intervention is an example of a theoretically-based prenatal physical activity intervention that targets these outcomes.

Up to 100 pregnant women (50 intervention arm, 50 control arm) will be recruited from the University of Colorado Clinics. Women in the intervention arm will participate in the 12-week MBMM+ intervention. Leiferman and her team propose to develop and test the feasibility and sustainability of the MBMM+ intervention to instill good healthy habits (e.g., prenatal physical activity, good sleep hygiene, stress management) during and beyond pregnancy. Findings from this study will be used to inform a future, large randomized trial.

Intervention Group:

The MBMM+ intervention is designed to promote the engagement in physical activity and takes into account barriers among pregnant women cited in our formative work such as lack of knowledge and skills, body changes and discomfort, feeling limited, and lack of social support. Uniquely, the MBMM+ program also targets sleep hygiene and mood to further support regular physical activity engagement. Over the years of working with pregnant women, we have observed that once women notice how their regular physical activity helps their mood and sleep patterns they are often more likely to continue engaging in regular physical activity. During the first four weeks of the MBMM+ program, participants will receive electronic informational handouts covering topics on weight management (content will be based in part on Co-I Downs' Healthy Mom Zone intervention such as informing on benefits and guidelines of healthy GWG, tips on healthy eating, energy balance, and sleep quality) as well as the benefits and safety concerns related to prenatal physical activity. Starting week 5 of the 12-week intervention, participants will attend two in-person, group physical activity sessions per week with each session lasting approximately 60 minutes and will be held at a local community center located close to the recruitment clinics. Sessions will be held on weekday evenings and weekend mornings as these times were preferred by pregnant women. Given that pregnant women often express a lack of knowledge about safe physical activities during pregnancy, preventing them from engaging in physical activity, each session will include both didactic and experiential components to increase knowledge and skill building. Sessions will begin with a didactic component covering overcoming barriers to physical activity, goal setting, self-monitoring, problem solving, topics related to mood (stress management, family/work balance, wellness wheel), sleep hygiene (setting routines, avoiding stimulants, environmental supports), and additional physical activity topics (e.g., managing physical activity in postpartum, overcoming relapses). Participants will be given educational materials in print and electronic form based on their preferences. The experiential component (i.e., physical activity) will be 30 minutes in duration and involve primarily walking, at a moderate intensity, based on national recommendations coupled with yoga. Our formative work suggests that mothers prefer walking and find it more enjoyable in the form of groups. We have chosen to also include yoga to provide options for ways to be active that also positively impact sleep and mood and pregnant women report desiring prenatal yoga. All walking sessions will be facilitated by the peer leaders. The yoga sessions will be taught by an experienced prenatal yoga instructor residing in Denver, CO.

Each session will have 3-4 peer leaders to help facilitate and model the physical activity component (i.e., will accompany women during their walking and yoga sessions to provide support and ensure safety (e.g., correct postures during yoga, monitoring exercise intensity and symptoms during walking sessions). Our MBMM formative work and expertise in community-based physical activity interventions suggests participants prefer peer group leaders because they foster a sense of community and social support within the group setting. Peer leaders will be compensated for their time working with the MBMM+ program and will be peer mothers from the community who are recent mothers (\< two years postpartum) who successfully engaged in regular physical activity during a previous pregnancy. Peer leaders will be identified by our research team, recreation center directors, and health care provider partners. At the end of every session, participants will check in with an assigned peer leader to discuss in small groups their weekly logs. Peer leaders will note the discussions that occurred amongst the participants in their group, describe barriers that were identified, problem-solving strategies that were suggested and used, and future goals/recommended action steps. This group work will help participants to learn ways to fit physical activity into their lifestyle and overcome barriers by receiving feedback from their peer leader and other group members. It will also ensure that the intervention is conducted and received in the way intended as the peer leaders and program manager/PI will review these small group progress notes each week and monitor intervention delivery.

Peer leader training and fidelity: Weekly, the research team (PI/program manager) will have phone calls and/or in-person meetings with the group peer leaders to debrief and address any issues that may arise. The program manager and/or PI will be on-site for all sessions to ensure quality control of intervention delivery and data collection efforts by peer leaders. The PI will conduct a training session before the onset of the intervention with the peer group leaders to cover topics including how to engage in safe and effective physical activity during pregnancy, an overview of behavioral change theory and the behavioral skills that the intervention is targeting, ways to garner social support and leadership skills. The PI has been extensively trained by the Cooper Institute in Prenatal-Postnatal Physical Activity. The yoga instructor will have been extensively trained in prenatal yoga.

Control Group:

Women randomized to the control group will complete a similarly structured 12-week program; electronic materials related to various prenatal topics including preparation for birth, birthing options, and responsive parenting will be distributed twice a week for the first 4-weeks of the program. Starting week 5 of the 12-week intervention, participants will attend two in-person, group sessions per week with each session lasting approximately 60 minutes and will be held at a local community center located close to the recruitment clinics. Sessions will be held on weekday evenings and weekend mornings as these times were preferred by pregnant women.
