National College Health Assessment
The National College Health Assessment (NCHA) is a nationally recognized research survey designed to assist schools in collecting precise data about their students' health habits, behaviors, and perceptions. Schools decide the topics to cover, survey method, target population, sample size, and time period (spring or fall).
Response rates vary: In the 2008 fall cycle, 40 institutions participated; 26,685 students were sampled. In the spring 2009 cycle, 117 institutions participated; 87,105 students were sampled.
Because the schools included in the NCHA are self-selecting, these data may not be generalizable to all schools (colleges and universities) and college students in the U.S.
