ObjectiveTo evaluate the available literature on the effects of continuous labor support among primiparous women.Data SourcesWe did a Medline search using the keywords "labor support," "doula," and "monitrice." Papers published in English from 1965 to May 1995 were eligible for this review. We also cross-checked all the references in the selected reports.Methods Of Study SelectionWe identified seven randomized clinical trials published during that period; four of these were eligible for our meta-analysis.Data Extraction And SynthesisMeta-analysis of four studies conducted among young, low-income, primiparous women who gave birth on a busy labor floor in the absence of a companion suggested that continuous labor support by a labor attendant shortens the duration of labor by 2.8 hours (95% confidence interval [CI] 2.2-3.4), doubles spontaneous vaginal birth (relative risk [RR] 2.01, 95% CI 1.5-2.7) and halves the frequency of oxytocin use (RR 0.44, 95% CI 0.4-0.7), forceps use (RR 0.46, 95% CI 0.3-0.7), and cesarean delivery rate (RR 0.54, 95% CI 0.4-0.7). Women with labor support also reported higher satisfaction and a better postpartum course.ConclusionLabor support may have important positive effects on obstetric outcomes among young, disadvantaged women. Further studies on benefit relative to cost are needed before a broad-scale program is advocated.
