ABSTRACT
OBJECTIVE:
This study aimed to review the literature comparing full-term induction of labor with expectant management in women with obesity on the risk of cesarean delivery and other adverse outcomes. DATA SOURCES A literature search was performed on PubMed, EMBASE, Scopus, ClinicalTrials.gov, and the Cochrane Library. This study had no time, language, or geographic restriction. STUDY ELIGIBILITY CRITERIA Studies were eligible if (1) they were cohort or randomized controlled trials, (2) they compared induction of labor at early or late term with expectant management, and (3) they included women with a body mass index of ≥30 kg/m2. Studies restricted to women with multiple pregnancy, premature rupture of membranes, or noncephalic presentation were excluded. The primary outcome was cesarean delivery. The secondary outcomes included maternal and neonatal mortality and morbidities and were evaluated.METHODS:
The risk of bias was assessed by 2 authors using the Risk of Bias In Non-Randomized Studies of Interventions tool. Only studies assessed with low or moderate risk of bias contributed to the meta-analysis. Data were combined to pooled relative risks and 95% confidence intervals using random effects models. The quality of evidence was assessed for selected outcomes.RESULTS:
Of the 232 studies identified, 13 were aligned with the inclusion criteria, and 4 cohort studies, including 216,318 women with induction of labor and 1,122,769 women managed expectantly, were included in the meta-analysis for the primary outcome. In women with obesity, full-term induction of labor was associated with a lower risk of cesarean delivery than expectant management (19.7% vs 24.5%; relative risk, 0.71; 95% confidence interval, 0.63-0.81). Moreover, this study found the same direction of the association for other selectedoutcomes:
severe perineal lacerations (relative risk, 0.65; 95% confidence interval, 0.48-0.89), maternal infection (relative risk, 0.42; 95% confidence interval, 0.21-0.84), perinatal mortality (relative risk, 0.41; 95% confidence interval, 0.18-0.90), low Apgar score (relative risk, 0.48; 95% confidence interval, 0.26-0.91), meconium aspiration syndrome (relative risk, 0.40; 95% confidence interval, 0.28-0.56), and macrosomia (relative risk, 0.57; 95% confidence interval, 0.43-0.75). Conversely, induction of labor was associated with an increased risk of instrumental vaginal delivery (relative risk, 1.12; 95% confidence interval, 1.02-1.22). The quality of evidence ranged from low to very low.CONCLUSION:
Full-term induction of labor in women with obesity may reduce the risk of cesarean delivery compared with expectant management, but the quality of the evidence is low.Palavras-chave
