‘Freshman 15’ A Myth Though Weight Does Increase in College
An Ohio State research scientist believes the “freshman 15” is a media myth, and could be a dangerous perception leading some students toward an eating disorder.
According to the national study, rather than adding “the freshman 15,” as it is commonly called, the average student gains between about 2.5 and 3.5 pounds during the first year of college.
Experts have also determined that college itself has a minimal impact on the weight gained as the typical freshman only gains about a half-pound more than someone the same age who didn’t go to college.
“Most students don’t gain large amounts of weight. And it is not college that leads to weight gain – it is becoming a young adult,” said Jay Zagorsky, Ph.D., co-author of the study and research scientist at Ohio State University’s Center for Human Resource Research.
“Repeated use of the phrase ‘the freshman 15,’ even if it is being used just as a catchy, alliterative figure of speech, may contribute to the perception of being overweight, especially among young women,” Zagorsky said. “Weight gain should not be a primary concern for students going off to college.”
Zagorsky conducted the study with economist Dr. Patricia Smith of the University of Michigan-Dearborn. The study will appear in a forthcoming issue of the journal Social Science Quarterly.
Researchers evaluated data from 7,418 young people from around the country who participated in the National Longitudinal Survey of Youth 1997.
The survey interviewed people between the ages of 13 and 17 in 1997 and then interviewed the same people each year since then. Among many other questions, respondents were asked their weight and college status each year.
Other studies have shown that college students tend to underestimate their weight by half a pound to 3 pounds. But if people are consistent in underestimating their weight from year to year, it would not impact these results, Zagorsky said.
Researchers determined that not more than 10 percent of college freshman gained 15 pounds or more — and a quarter of freshman reported actually losing weight during their first year.
On average, women gained 2.4 pounds during their freshman year, while men gained 3.4 pounds.
The researchers examined a variety of factors that may be associated with freshman weight gain, including whether they lived in a dormitory, went to school full or part-time, pursued a two-year or four-year degree, went to a private or public institution, or was a heavy drinker of alcohol (consuming six or more drinks on at least four days per month.)
None of these factors made a significant difference on weight gain, except for heavy drinking. Even then, those who were heavy drinkers gained less than a pound more than students who did not drink at that level.
Zagorsky said it was particularly significant that dorm living did not add to weight gain, since one hypothesis has been that the dorm environment encourages weight gain during the freshman year.
“There has been concern that access to all-you-can-eat cafeterias and abundant fast food choices, with no parental oversight, may lead to weight gain, but that doesn’t seem to hold true for most students,” he said.
The results do show, however, that college students do gain weight steadily over their college years.
The typical woman gains between seven and nine pounds, while men gain between 12 and 13 pounds. So, rather than a “freshman 15”, a modest college-related gain is typical.
The researchers also examined what happened to college students’ weight after they graduated. They found that in the first four years after college, the typical respondent gained another 1.5 pounds per year.
“College students don’t face an elevated risk of obesity because they gain a large amount of weight during their freshman year,” Zagorsky said. “Instead, they have moderate but steady weight gain throughout early adulthood. Anyone who gains 1.5 pounds every year will become obese over time, no matter their initial weight.”
Although most students don’t need to worry about large weight gains their freshman year, Zagorsky said they still should focus on a healthy lifestyle.
“Students should begin developing the habit of eating healthy foods and exercising regularly. Those habits will help them throughout their lives.”
