What is the leading cause of infant death in the United States?

The leading cause of infant death in the United States is related to congenital malformations and chromosomal abnormalities. These conditions often result in significant health complications that can lead to mortality shortly after birth. Congenital malformations refer to structural changes in the body that are present at birth, and they can affect various organ systems, making it challenging for infants to survive without medical intervention.

The prevalence of these conditions can be attributed to various factors, including genetic predispositions, environmental influences, and maternal health during pregnancy. Advances in medical technology and prenatal care have improved our ability to identify and manage many of these issues, but they still account for a substantial proportion of infant deaths.

In contrast to other causes listed, while Sudden Infant Death Syndrome (SIDS) is a significant concern, it ranks lower than congenital anomalies in statistics. Similarly, respiratory distress and issues related to low birth weight are critical health concerns but generally fall behind congenital malformations when discussing overall infant mortality rates. Understanding these distinctions helps in addressing the various factors that contribute to infant health and survival rates.
