Premature babies studied as young adults show distinctive disadvantages. They are more likely to have one or more chronic health problems, especially neurosensory conditions (cerebral palsy, blindness, or deafness), and are shorter than normal-weight babies. They also have lower IQs, score lower on academic achievement tests, and are less likely to have graduated from high school or have enrolled in a four-year college. However, 51% have IQ scores within the normal range; 74% have completed high school; and 41% are pursuing post-secondary education.
