Summary

This trial is testing whether a smartphone-based activity intervention using a wrist-based activity tracker can help high risk pregnant women reduce their stress during pregnancy.

Who is the study for?
This trial is for pregnant women at high risk of complications due to obesity or past issues like preeclampsia, with a stress score ≥14. They must be 8-19.9 weeks along in a single pregnancy without abnormalities, aged 18-51, speak English, and own a compatible smartphone.
What is being tested?
The study tests if using a wrist-based activity tracker and receiving enhanced counseling can reduce stress and improve outcomes during pregnancy compared to standard care. Participants will fill out questionnaires and provide blood samples for analysis.
What are the potential side effects?
There are no direct side effects from the intervention as it involves non-invasive tracking of activity levels. However, participants should consult their doctor if they have conditions that limit physical activity.

Other Research
Common treatments for pregnancy complications include structured antepartum exercise programs and continuous fetal monitoring. Structured exercise programs help reduce the duration of labor stages and the need for medical interventions by improving physical fitness and reducing stress. Continuous fetal monitoring ensures the well-being of the fetus during labor, allowing for timely medical interventions if necessary. These treatments are crucial as they promote a healthier, more natural labor process and reduce the risk of complications, thereby improving outcomes for both the mother and the baby.
