Stillbirth rate is high in Brazil, and it is important to identify its determinants. A nested case-control was conducted to explore the determinants of fetal death in a population treated at public services in Rio de Janeiro from 2002 to 2004. Data were collected from mothers' interviews and medical records. A structured model was proposed to perform statistical analysis, attributing hierarchical levels: socioeconomic factors (distal level), reproductive, behavioral, and healthcare determinants (intermediate level), and fetal biological characteristics (proximal level). According to the findings, work stability, stable marital status, presence of a companion during admission, and adequate prenatal care had a protective effect against fetal death, while domestic violence, maternal morbidity, and intrauterine growth restriction increased the risk. Quality of prenatal care showed a large protective effect, thus becoming a key strategy for reducing fetal mortality in populations with low socioeconomic status.
