Changes in Weight and Health Behaviors from Freshman through Senior Year of College

ObjectiveTo assess weight changes, exercise and diet behaviors among college students from the beginning of freshman year until the end of senior year.DesignLongitudinal observational study.SettingPrivate university in St. Louis, Missouri.ParticipantsCollege students (138 females, 66 males).Main Outcome MeasuresWeight and height were measured, body mass index (BMI) was calculated, and exercise and dietary behaviors were assessed by questionnaire.AnalysisChanges in weight, BMI, exercise, and dietary patterns from the beginning of freshman year to the end of senior year.ResultsFemales gained 1.7 ± 4.5 kg (3.75 ± 9.92 lb) [mean ± SD] from freshman to senior year, and males gained 4.2 ± 6.4 kg (9.26 ± 14.11 lb) (both P < .001). Weight changes were highly variable between students, however, ranging from −13.2 kg to +20.9 kg (−29.10 to +46.08 lb).Conclusions and ImplicationsWeight gain was common but variable among college students. Importantly, exercise and dietary patterns did not meet the recommended guidelines for many college students, which may have long-term health implications.
