[Continuous support during childbirth to reduce cesarean sections: evidence brief for policy]

Cesarean section rates have increased globally in the last 30 years, representing more than 56% of total births in Brazil. Considering the impacts of elective cesarean sections in maternal and child health, this review aimed to present an option to reduce these rates. We used the SUPPORT tools to summarize the best evidence. We included systematic reviews published in English, Portuguese, or Spanish, which focused on non-clinical interventions. Continuous support during labor and birth was described in four systematic reviews as an option to reduce cesarean rates (down to -51%). It also decreased unnecessary clinical interventions during labor, the duration of labor, and the likelihood of delivering a baby with a low Apgar score at five minutes. Moreover, continuous support improved breastfeeding, postpartum recovery of women during the puerperium period, and increased women's satisfaction with the birth experience and the possibility of spontaneous vaginal deliveries. The continuous support was beneficial for women and newborns. The intervention fosters respect, safety, and quality during birth, besides reducing hospital costs. Therefore, it is an effective strategy that should be adopted in hospitals and other health services to improve women's access to their rights.
