[Longitudinal care: factors associated with adherence to postpartum follow-up according to data from PMAQ-AB].

The aim was to identify factors of longitudinal care associated with women´s adherence to postpartum consultation in Brazil. This was a cross-sectional study of data from 19,177 postpartum women who participated in the external assessment of the third cycle of the Brazilian National Program for Improvement of Access and Quality of Basic Care (PMAQ-AB), 2017. The dependent variable was postpartum consultation, and the independent variables, grouped hierarchically, were sociodemographic and economic at the distal level and issues analogous to longitudinal care at the proximal level. Multiple logistic regression analysis was performed with hierarchical entry of variables, where sociodemographic and economic variables were used to adjust the model. The results showed that 53% of women had undergone postpartum follow-up. The odds of adherence to postpartum follow-up were higher in women who received a home visit by a community health agents in the first week after childbirth (OR = 4.81), those with seven or more prenatal consultations (OR = 2.74), those who had sought care at the health unit in question (OR = 1.21), and those who had been seen by the same physician (OR = 1.14). In conclusion, the proportion of postpartum consultations was low (53%), and adherence to postpartum follow-up was higher when women received visits by community health agents, were accompanied by the same physician, had regular prenatal care, and had a specific healthcare unit as their regular source of care. Consistent longitudinal care was identified as an attribute of primary care that should be strengthened to improve postpartum care.
