ABSTRACT
Background
Matrix support (MS) in women's health is a normative work process that aims to qualify and increase the resolvability of professionals working in prenatal care in Primary Health Care (PHC).
Objective
To evaluate the effect of MS on the most prevalent adverse perinatal outcomes in a state capital city in the Southeast region of Brazil.
Method
A cohort study evaluating prematurity, low birth weight, and early neonatal mortality in infants of women followed up in PHC services in the city of Vitória from 2013 to 2014.
Results
The final hierarchical analysis model, which included 443 newborns, showed that the larger the number of previous pregnancies (OR 4.39, CI 1.93-10.0) and the smaller the number of prenatal consultations (OR 4.99, CI 2.18-11.42), the greater the chances of a pregnancy progressing to an adverse perinatal outcome. No effect of MS on outcomes was observed.
Conclusion
The proposed hierarchical model demonstrated that MS has no influence on the adverse perinatal outcomes studied.
