How does premature labor affect infant mortality?
Preterm babies have a higher risk of complications that could lead to death within the first year of life.

In the United States, more than one-third of infant deaths are related to a premature birth.
What problems do premature babies have an increased risk of having as they get older?

Do premature babies have lung problems later in life?
For some preterm infants, particularly those with bronchopulmonary dysplasia, obstructive lung disease persists into adulthood. They are very likely to develop chronic obstructive pulmonary disease or similar disease later in life .
Does premature birth affect brain development?
When babies are born too early, their normal brain development is interrupted , and they are more likely to have problems later on in their lives. Disrupting brain development results in various types of brain injury depending on how early the baby is born.
Is the leading cause of death in newborns?

How does premature birth affect a child’s development?
Preterm babies can suffer lifelong effects such as cerebral palsy, mental retardation, visual and hearing impairments , and poor health and growth. Babies born only a few weeks early (late preterm, 34-36 weeks) often have long-term difficulties such as: Behavioral and social-emotional problems. Learning difficulties.
Are premature babies slower to develop?
Late preterm babies tend to catch up to full-term babies quickly. Babies who were born earlier than that may develop more slowly and have setbacks. Extremely preterm babies are more likely to have serious, lasting disabilities.
