Summary
In 2004, the U.S. infant mortality rate slightly decreased. Significant disparities in infant mortality were observed across racial/ethnic groups and linked to preterm birth and low birthweight.
Area of Science:
- Demography
- Public Health
- Perinatology
Background:
- Infant mortality statistics are crucial for assessing population health.
- The linked birth/infant death data file provides comprehensive data for analysis.
- Understanding trends and disparities in infant mortality is essential for targeted interventions.
Purpose of the Study:
- To present 2004 infant mortality statistics using the linked birth/infant death data file.
- To analyze infant mortality rates by maternal and infant characteristics.
- To identify disparities and risk factors associated with infant mortality.
Main Methods:
- Descriptive tabulations of data from the linked birth/infant death file.
- Calculation and interpretation of infant mortality rates, neonatal mortality rates, and postneonatal mortality rates.
- Analysis of infant mortality by maternal demographics, infant characteristics, gestational age, and birthweight.
Main Results:
- The U.S. infant mortality rate was 6.78 per 1,000 live births in 2004.
- Significant racial/ethnic disparities were observed, with non-Hispanic black mothers having the highest rates.
- Infant mortality was higher for preterm infants, low birthweight infants, male infants, and multiple births.
- Preterm-related causes accounted for 36.5% of infant deaths, with notable disparities by race/ethnicity.
Conclusions:
- Infant mortality rates show persistent disparities across racial and ethnic groups.
- Preterm birth and low birthweight remain major contributors to infant mortality.
- Targeted public health strategies are needed to address disparities and reduce infant mortality, particularly among vulnerable populations.

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
01:22Applications of Life Tables
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
01:29Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
01:20Actuarial Approach
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
