Sleep disorders and deficits are a national U.S. health concern, and college students report more sleep difficulties than the general population. Most published studies examine college students as a homogenous population or focus on professional (e.g. medical) students. This study compares sleep patterns of undergraduate and graduate students from a national U.S. sample using the American College Health Association-National College Health Assessment (ACHA-NCHA) II survey. Graduate students on average reported better sleep behaviors; however, graduate students' sleep habits were still poor and these students could also benefit from intervention.
