Continuous labor support and doulas

Research for childbirth educators

Research on continuous support in labor includes a large systematic review of continuous support for women during childbirth, along with studies that look specifically at doulas. These examine how doula care relates to labor duration, maternal health and vaginal birth, how doulas compare with trained lay companions and routine midwifery care, and how a shift-model doula program worked in a large safety-net teaching hospital. A pilot randomized trial even looked at whether continuous doula support relates to serotonin release.

Other papers ask different questions. A qualitative evidence synthesis explores how women experience labour companionship, a study reports young Black mothers' perspectives on community-based doulas, and others look at the emotional labour of doula work and at one-on-one professional support in relation to physiological birth. A committee opinion from ACOG on approaches to limit intervention during labor and birth also appears in the tracked set.

Parents commonly ask what a doula does, how a doula differs from a partner or a nurse, and whether support changes how birth goes. Researchers continue to look at these questions from clinical, social and experiential angles.

An educator may want slides to describe the different roles of support people accurately and to reflect both outcome studies and women's own accounts. The papers listed below are the ones the Hub tracks on this topic.
