There are a number of other risk factors for premature labour and delivery. Some of these risks, such as anemia, slow maternal weight gain, stressful work habits, smoking, drinking alcohol, and using drugs like cocaine, can be rectified during pregnancy.
Those final weeks in the womb are crucial for healthy weight gain and for the full development of various vital organs, including the brain and lungs. This is why premature babies may have more medical problems and may require a longer hospital stay. They may also have long-term health issues, such as learning disabilities or physical disabilities. In the past, premature birth was the major cause of infant death in the United States. Today, the quality of care for newborns has improved, as have the survival rates of premature babies. Yet premature birth is still the top cause of infant death worldwide, according to the Centers for Disease Control and Prevention.
