Almost 40 percent of Harvard students abstained from sex in the past year, and of those that have had sex, almost all of them have had only one or two partners.

The survey also showed that students at Harvard frequently do not get their health information from sources that they themselves consider believable. While television falls at the very bottom of believability, about a third of students get their health information from TV-more than the 28.9 percent of students receiving information from what students deem the most believable source, college health educators.

"I think we have a lot of work to do about getting our messages across about good health, physical activity and nutrition," Rosenthal said. "I think we're doing better than other schools in many issues. However, that doesn't excuse us from trying to do better. We're trying to share this with the faculty and with the students."

Mental health results showed a high number of students feel "overwhelmed" or "intense sadness" frequently. Nearly a fifth of Harvard students reported feeling "intense sadness" 11 or more times-the highest possible answer-in the last school year.

In the same vein, the most popular response to feeling "overwhelmed" in the past school year was 11 or more times, at 35.4 percent.

Fatigue was also shown to be a factor, with a majority of students reporting that more than half of mornings they wake up not feeling rested.

A quarter of students report feeling "slightly overweight" and 36.8 percent are attempting to shed pounds.

UHS officials said they plan to take the survey's results into consideration in their student care programs in the future.
