An Anxiety ‘Epidemic’ Is Brewing

April 26, 2019

The number of 18- to 26-year-old students who report suffering from anxiety disorder has doubled since 2008, perhaps as a result of rising financial stress and increased time spent on digital devices, according to preliminary findingsreleased by a team of UC Berkeley researchers.

A team led by physician David M. Eisenberg of Harvard Medical School determined that use of herbs for physical and mental problems including anxiety had risen 380 percent in seven years.

The percentage of all students nationally who reported being diagnosed with or treated for anxiety disorder climbed from 10 percent in 2008 to 20 percent in 2018, according to the findings by a research team led by Richard Scheffler, a professor at the Goldman School of Public Policy and School of Public Health.

Rates of anxiety disorder grew at higher rates for students who identified as transgender, Latinx and black, and they increased the closer all students got to graduation.

“It is what I am calling a ‘new epidemic,’ and that the data supports using that term, on college campuses,” Scheffler said. “We need a heightened national awareness of this very serious epidemic.”

Scheffler and his team examined nine years of data from the annual student National College Health Assessment survey and the National Longitudinal Survey of Youth — two nationwide examinations of student well-being. The group also conducted 45-minute interviews with 30 UC Berkeley students who identified as suffering from anxiety.

While Scheffler said he cannot firmly establish the causes for the rise in anxiety, he found strong correlations between anxiety disorder and financial instability, the amount of leisure time spent on digital devices and the level of education attained by a young adult’s mother.

“The correlations and the data are pretty powerful,” he said.

Factors Increasing Anxiety

Specifically, the findings show that:

Young adults who come from families that have trouble paying bills are 2.7 times more likely to have anxiety than students who come from families that have no difficulty paying bills.

Young adults who spend more than 20 hours of leisure time per week on digital devices were 53 percent more likely to have anxiety than young adults who spend fewer than 5 hours a week on digital devices.

Young adults with mothers who had at least an undergraduate degree had a 45 percent greater chance of having anxiety than young adults whose mothers had less than a college degree. The surveys used in the analysis did not ask about the fathers’ level of education.

Scheffler also found that anxiety is associated with other serious problems beyond the overwhelming feelings of worry or nervousness associated with the disorder.

A student with anxiety is 3.2 times more likely to abuse alcohol or drugs, the findings show. Other negative outcomes correlated with anxiety included increased probability of having been sexually assaulted or attempting suicide.

All factors being equal, Scheffler also found that between 2008 and 2014, young adults with anxiety earned 11 percent less than those without anxiety.

“Anxiety has really very dire consequences for these students,” Scheffler said. “That’s a lot of pain and suffering.”

‘Something’s Going On Here’

Scheffler, who joined UC Berkeley’s faculty in 1981, said he first began thinking about student anxiety 10 years ago, when he looked out at the 100 students in his lecture hall and saw faces stricken with worry.
