Presence of a full-time companion in Brazilian maternities linked to the Rede Cegonha

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

The objective was to estimate the proportion of women with a full-time companion in Brazilian maternities linked to the Rede Cegonha (RC) and to compare them between the macro-regions in Brazil. A nationwide study, carried out from December/2016 to October/2017. 10,665 puerperal women from all regions of Brazil participated in the study, who gave birth at one of 606 maternity hospitals with a regional action plan approved by RC. Proportions and respective 95% confidence intervals were estimated, adjusted for the cluster effect, by comparing the macro-regions using Wald’s chi-square test. The presence of a full-time companion occurred in 71.2% of maternities, being higher among women aged 20-35 years, brown-skinned, with higher education, married, and assisted in vaginal delivery. Almost 30% of puerperal women did not have a full-time companion. In the Southeast and Midwest regions, self-declared black women, with less schooling and unmarried women were less accompanied. The moment of delivery had less presence of the companion (29.2%). Despite the advances, this right is still not fully fulfilled, pointing to the occurrence of social inequities among Brazilian macro-regions.
