Summary
This study analyzed 17,092 births in San Luis Potosí, revealing high rates of precocious fetal and hebdomadal mortality, especially among newborns with low birth weight or early gestation. Placental insufficiency and congenital abnormalities were key causes of neonatal death.
Area of Science:
- Perinatology
- Public Health
- Neonatal Medicine
Context:
- Collaborative study involving ten hospitals in San Luis Potosí, Mexico.
- Data collected from January 1st to December 31st, 1988, excluding home births and specific hospital births (approx. 10%).
- Total registered births: 17,092, including 204 mortinates.
Purpose:
- To determine and analyze fetal, hebdomadal, and perinatal mortality rates based on birth weight and gestational age.
- To identify the primary causes of neonatal mortality in the studied population.
Summary:
- Precocious fetal mortality (500-999g): 391.30/1000; (20-27 weeks): 140.40/1000.
- Late fetal mortality (≥1000g): 9.25/1000; (≥28 weeks): 9.89/1000.
- Hebdomadal mortality (500-999g): 571.40/1000; (20-27 weeks): 159.40/1000.
- Perinatal mortality (≥1000g): 21.10/1000; (≥28 weeks): 22.38/1000.
- The Mexican Institute of Social Security (IMSS) reported significantly higher mortality rates compared to the global average for the study area.
- Causes of death in 199 mortinates: 49.7% placental circulation insufficiency, 17.1% major congenital abnormalities.
Impact:
- Highlights significant disparities in neonatal outcomes, particularly within the IMSS system.
- Identifies critical areas for intervention, such as improving prenatal care and addressing placental health.
- Provides baseline data for future public health initiatives aimed at reducing neonatal mortality in the region.
