Investigating the Feasibility and Preliminary Effects of Yoga on Excessive Gestational Weight Gain

5 gennaio 2021 aggiornato da: Jennifer Huberty, Arizona State University

The Power of Yoga: Investigating the Feasibility and Preliminary Effects of Yoga on Excessive Gestational Weight Gain

This study will test the feasibility (i.e., acceptability, demand) of a 12-week prenatal yoga intervention on excessive gestational weight gain (GWG) in pregnant women in the second trimester (enrolled at 12-24 weeks). Participants will be randomized into the prenatal yoga intervention or a pregnancy education (e.g., information on preparing for motherhood, labor and delivery etc.) control group. Participants in both groups will be asked to attend one 75 minute class per week.

The investigators hypothesize that prenatal yoga intervention will be feasible for pregnant women.

The study aims are as follows:

Primary Aim: Determine the feasibility (i.e., acceptability, demand) of a 12-week prenatal yoga intervention in pregnant women. In a randomized controlled pilot study comparing prenatal yoga to a pregnancy education control condition, the investigators will assess 1) acceptability (defined as satisfaction, intent to continue use, perceived appropriateness) and 2) demand (defined as attendance/adherence).

Exploratory Aim 1: Ascertain the preliminary effects of prenatal yoga on excessive GWG [i.e., weight gain exceeding Institute of Medicine (IOM) recommendations]. The investigators will compare weight change between intervention and control groups.

Exploratory Aim 2: Explore the potential mediators (i.e., mindfulness, self-regulation) on the effect of prenatal yoga on excessive GWG.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Prenatal yoga
Each class will be outlined as follows: 1) opening greeting/intention setting, 2) pranayama (i.e., breathing exercises), 3) warm-up/sun salutations (i.e., flowing sequence), 4) yoga sequence (e.g., combination of sun salutations, vinyasa, and standing, seated, and/or balancing poses), 5) cool-down 6) Savasana (i.e., final resting pose), and 7) class closing. Meditation and breath awareness (e.g., linking each movement with breath) will be emphasized throughout each class. All classes will focus on safety and alignment and be appropriate for women during pregnancy by incorporating modifications to poses/exercises as necessary (e.g., yoga block, strap). Certified yoga instructors with a bachelors degree in a health related field and experience teaching pregnant women will instruct all yoga classes. Participants will be provided with a 'yoga during pregnancy' safety packet that includes a list of prenatal yoga poses that women may do at their own leisure at home.
Comportamentale: Prenatal yoga
The prenatal yoga classes will be offered at Urban Wellness (2024 N. 7th St., Phoenix, AZ 85006). Classes will be offered Tuesdays's from 4:15-5:30 pm and Saturday's from 9:00-10:15 am. Participants will be able to attend both classes if they so choose but are only asked to attend 1/week. Participants will be asked to arrive to class at least 10 minutes early in order for the research team to collect their weight in a private room. Additionally, if participants have attended at least 70% of classes (1 per week for 8/12 weeks), participants will be able to attend sessions up until birth (beyond the 12-week intervention) if they so choose. If participants decide to attend classes beyond the 12-week intervention the investigators will continue to collect their weight at each session.
Comparatore attivo: Pregnancy education
Participants will be asked to attend a group-based pregnancy education group (similar to a birth education class). The class format will include a didactic portion followed by group discussion (N=12). The following evidence-based topics (based on the American College of Obstetrics and Gynecologists) to be discussed may include (but not limited to): financial management in preparation for baby, preparing for labor and delivery, transitioning into motherhood, sleep hygiene, and baby bonding. A labor and delivery nurse and certified Dula will instruct all classes.
Comportamentale: Pregnancy education
Pregnancy education classes will be offered at the Arizona Biomedical Collaborative Building on ASU Phoenix Campus. Classes will be offered on Tuesday's from 5:30-6:45 pm and Saturday's from 9:00-10:15 am. Participants will be able to attend both classes if they so choose but are only asked to attend 1/week. Participants will be asked to arrive to class at least 10 minutes early in order for the research team to collect their weight in a private room. Additionally, if participants have attended at least 70% of classes (1 per week for 8/12 weeks), participants will be able to attend sessions up until birth (beyond the 12-week intervention) if they so choose. If participants decide to attend classes beyond the 12-week intervention the investigators will continue to collect their weight at each session.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Acceptability via satisfaction survey at post-intervention
Lasso di tempo: post-intervention (12-weeks)
Acceptability (defined as satisfaction, intent to continue use, perceived appropriateness); Benchmarks for acceptability include ≥70% of the sample will report the yoga intervention to be a satisfactory, useful, and appropriate modality to prevent excessive GWG.
post-intervention (12-weeks)
Demand (attendance/adherence) of yoga intervention
Lasso di tempo: Weekly (during 12-week intervention)
Demand was measured using attendance/adherence to the yoga intervention. Attendance was tracked by a researcher who was present at each yoga session. Benchmarks for demand include ≥60% of participants in each group will attend one class per week.
Weekly (during 12-week intervention)

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Number of participants with excessive GWG (total GWG from baseline to delivery)
Lasso di tempo: Weekly (during 12-week intervention) and at delivery (up to 42 weeks gestation)
Weight gain exceeding IOM recommendations
Weekly (during 12-week intervention) and at delivery (up to 42 weeks gestation)
Mindfulness (mean change from baseline)
Lasso di tempo: Baseline, post-intervention (12-weeks)
Self-report mindfulness scores via Mindful Attention Awareness Scale (MAAS); 15-item questionnaire with score ranges 1-6. Higher scores reflect higher levels of dispositional mindfulness.
Baseline, post-intervention (12-weeks)
Self-awareness (mean change from baseline)
Lasso di tempo: Baseline, post-intervention (12-weeks)
Self-report self-awareness scores via Self-Awareness Outcomes Questionnaire (SAOQ); Consists of 38 items measuring 4 subscales (reflective self-development, acceptance, proactive at work, and emotional costs). Score ranges for each subscale are between 1-5. Higher scores represent a greater frequency of experienced outcomes.
Baseline, post-intervention (12-weeks)
Emotion Regulation (mean change from baseline)
Lasso di tempo: Baseline, post-intervention (12-weeks)
Self-report emotion regulation scores via Emotional Regulation Questionnaire (ERQ); Consists of 10 items measuring 2 subscales (reappraisal items, suppression items). Score ranges for each subscale are between 1-7. The higher the scores, the greater the use of the emotional regulation strategy.
Baseline, post-intervention (12-weeks)
Sleep Quality (mean change from baseline)
Lasso di tempo: Baseline, post-intervention (12-weeks)
Self-report sleep quality via Pittsburgh Sleep Quality Index (PSQI); Consists of 10-items. In scoring the PSQI, seven component scores are derived ranging from 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality.
Baseline, post-intervention (12-weeks)
