Multilevel Community Engagement to Inform a Randomized Clinical Trial

OBJECTIVE

To explore how patients, community-based perinatal support professionals, and health system clinicians and staff perceived facilitators and barriers to implementation of a randomized clinical trial (RCT) designed to optimize Black maternal heart health.

METHODS

This article describes the formative work that we believed needed to occur before the start of the Change of H.E.A.R.T (Here for Equity, Advocacy, Reflection and Transformation) RCT. We used a qualitative, descriptive design and community-based, participatory approach, the latter of which allowed our team to intentionally focus on avoiding harm and equalizing power dynamics throughout the research process. Data were collected between November 2021 and January 2022 through six semistructured focus groups that included attending physicians and midwives (n=7), residents (n=4), nurses (n=6), support staff (n=7), community-based perinatal support professionals (n=6), and patients (n=8).

RESULTS

Four primary themes emerged. The first three themes were present across all groups and included: 1) Trauma in the Community and Health System, 2) Lack of Trust, and 3) Desire to Be Heard and Valued. The fourth theme, Hope and Enthusiasm, was expressed predominantly by patients, community-based perinatal support professionals, residents, and support staff, and less so by the attending physician group.

CONCLUSION

Participants articulated a number of key sentiments regarding facilitators and barriers to implementing Change of H.E.A.R.T. We noted variability in perceptions from different groups. This has important implications for health equity efforts in similarly underresourced health systems where Black birthing people experience the greatest morbidity and mortality.

Targeting pregnancy-related weight gain to reduce disparities in obesity: Baseline results from the Healthy Babies trial

BACKGROUND

Obesity affects African American women more than any other group in the US. Pregnancy represents a critical life stage of heightened vulnerability for new or persistent obesity, yet few interventions have been effective in reducing excessive gestational weight gain among African American women. We describe the design and baseline findings of Healthy Babies, a two-arm randomized controlled trial testing a mobile health intervention to minimize excessive gestational weight gain versus usual care in this high risk group.

METHODS

African American women in early pregnancy were recruited from two large obstetric practices as well as Philadelphia Women, Infants, and Children's clinics. Participants randomized to the intervention received behavior change goals, daily text messages with feedback, web-based weight gain graphs, health coaching, and a Facebook support group. Data collection included baseline (<22 weeks' gestation), 36-38 weeks' gestation, and 6-month postpartum anthropometric measures and assessments of demographics, contextual factors and behavioral targets. The primary outcome was prevalence of excessive gestational weight gain.

RESULTS

Among participants at baseline (n = 262), the majority met criteria for obesity (63%), were multiparous (62%), single (77%), and were on average 25.6 ± 5.4 years old with a gestational age of 13.9 ± 4.1 weeks. While 82% completed high school, 61% met criteria for inadequate health literacy. Nearly 20% were food insecure. Eighty-eight percent reported a gestational weight gain goal discordant with Institute of Medicine guidelines. There were no significant differences in baseline characteristics between study arms.

CONCLUSIONS

Participants represent a high-risk group for excessive gestational weight gain with demonstrated need for intervention.

Influence of Sleep Duration on Postpartum Weight Change in Black and Hispanic Women

OBJECTIVE

The primary purpose of this study was to examine associations of objectively measured sleep duration with weight changes in black and Hispanic mothers over the first postpartum year.

METHODS

Data were from 159 mothers (69% black, 32% Hispanic). Nocturnal sleep duration was assessed using wrist actigraphy at 6 weeks and 5 months post partum, examined as a continuous variable and in categories (< 7 vs. ≥ 7 hours/night, consistent with American Academy of Sleep Medicine recommendations). Body weights were abstracted from medical records in pregnancy and measured at 6 weeks, 5 months, and 12 months post partum. Outcomes included early postpartum (6 weeks to 5 months) and late postpartum (5 to 12 months) weight changes.

RESULTS

The majority of participants slept < 7 hours/night at 6 weeks (75%) and 5 months (63%) post partum. Early postpartum weight change did not differ by 6-week sleep duration category. By contrast, adjusted average late postpartum weight gain (SE) was 1.8 (0.7) kg higher in participants sleeping < 7 hours/night at 5 months post partum compared with those sleeping ≥ 7 hours/night (P = 0.02). Results did not show statistically significant associations of continuous measures of sleep duration, nor of measures of sleep quality, with postpartum weight changes.

CONCLUSIONS

Sleeping < 7 hours/night was associated with late postpartum weight gain in minority mothers.
