The Freshman 15: A Critical Time for Obesity Intervention or Media Myth?

Abstract

Objectives We test whether the phrase “ F reshman 15” accurately describes weight change among first‐year college students. We also analyze freshmen's weight change during and after college. Methods This is the first investigation of the “ F reshman 15” to use a nationally representative random sample, the N ational L ongitudinal S urvey of Y outh ( NLSY 97). The data are analyzed using descriptive statistics, regression analysis, simulations, and longitudinal analysis. Results Freshmen gain between 2.5 to 3.5 pounds, on average, over the course of their first year of college. Compared to same‐age noncollege attendees, the typical freshman gains only an additional half‐pound. Instead of a spike in weight during the freshman year, college‐educated individuals exhibit moderate but steady weight gain during and after college. Conclusion Anti‐obesity efforts directed specifically at college freshmen will likely have little impact on obesity prevalence among young adults.
