PMID 41712630WHAT IT FOUND
Most fetal deaths in Brazil were recorded as perinatal conditions.
The share tied to maternal complications and chromosomal abnormalities rose, while the share tied to hypoxia and asphyxia fell. Maternity nurses can keep prenatal monitoring and syphilis screening central.
Key findings
01In Brazil, 164.504 fetal deaths were registered from 2011 to 2020, with most under ICD-10 Chapter 16, then Chapter 17 and Chapter 1.
02Proportional mortality from intrauterine hypoxia and birth asphyxia decreased for early, intermediate, and late fetal deaths.
03Proportional mortality from chromosomal abnormalities not classified elsewhere and fetus and newborn affected by maternal factors and complications of pregnancy, labor, and delivery showed statistically significant upward trends for all fetal death types.

What it does not show
The study used only death certificate data from the national Mortality Information System, so the quality of the records was not directly controlled. Underreporting, coding errors, and incomplete diagnosis records may have affected the underlying cause. Because the design was observational, it cannot show causality between care and fetal deaths. It could not evaluate clinical, maternal, and fetal variables not recorded, or public health interventions during the period. The paper reports trends in death records, not tested effects of nursing or obstetric care.
Declared interests
This work received financial support from Capes in Brazil. No other conflicts of interest are stated.
The easy way to misread this
Do not read the downward trend in hypoxia and asphyxia as proof that care improved, or the upward trends as proof that care worsened. The study used death certificate records and could not assess causality, unrecorded clinical variables, or public health interventions.
