Clinical Trial Summary

Pregnancy outcomes, such as excessive gestational weight gain and gestational diabetes, are linked to long and short-term maternal and child health. Interventions aimed at improving health behaviors, such as sedentary behavior (SB; i.e., any behavior in a seated or reclining position with low energy expenditure) are attractive because they are low-cost, can be disseminated in a wide variety of populations once pregnancy begins, and do not require drugs or prescriptions. Studies have linked SB to some pregnancy outcomes. To the investigators' knowledge, no studies have tested the efficacy of an intervention to reduce SB in pregnant women. Over 90% of reproductive aged women own a smartphone with similar rates of ownership among black, white, and Hispanic/Latina women, and most adults carry smartphones while awake. Smartphones can monitor SB without additional equipment. Thus, smartphones offer a streamlined opportunity to intervene on SB. The purpose of the research is to evaluate the effectiveness and perception of an mHealth intervention aimed at changing SB in pregnant women. Investigators will survey providers regarding their SB opinions and counseling practices


Description:

Investigators will recruit 28 pregnant women, 14 per arm, to participate in this pilot randomized, controlled study. Particiants will complete an in-person baseline study visit in early pregnancy (< week 16). The visit will occur in the Public Health Research Center, Discovery Building, or at a Prisma Health facility. Measurements at the in-person visit (~ 1 hr) include demographics, surveys regarding current and pre-pregnancy PA and SB, medical and pregnancy history, height, and weight. All participants will be given an activPAL(TM) (Glasgow, UK) at V1 to objectively measure SB for 1 week using gold-standard methodology. At the end of the 1-week run-in period (i.e., the week during which SB is objectively measured prior to randomization), participants will mail back the activPAL(TM) and be randomized to the mHealth SB intervention or control group for 12 weeks. SB will be objectively measured again using the activPAL(TM) from week 11-12 of the study. Surveys (Nausea and Vomiting of Pregnancy, Global Health Scales, inquiry about new diagnoses) will be administered remotely in week 5 and week 11. A recruitment opinion survey will be administered remotely in week 5 to inform future recruitment efforts. Surveys related to the intervention platform and perceived effectiveness will be administered remotely at week 12 to participants in the experimental group. Investigators will ask about new diagnoses or adverse events at week 5 and week 11. Investigators will link to participants' medical charts and abstract in-clinic body weight, the results of the third trimester glucose tolerance test, and any other pregnancy-related diagnoses. Investigators will survey Ob/Gyn clinicians (doctors, residents, and nurses) regarding their perceptions of SB during pregnancy.
