Prenatal alcohol and tobacco exposure at any level impacted newborn brain activity

Takeaway

  • Prenatal exposure to alcohol (PAE) and tobacco smoking (PTE) at any level was associated with changes in newborn brain activity; PAE was associated with increased low-frequency brain activity, whereas moderate or high continuous PTE was associated with decreased high-frequency brain activity.

Why this matters

    The results showed that any levels of PAE and PTE were associated with newborn brain development. This highlights that further studies are required to determine a safe level of alcohol or tobacco use during pregnancy.
