A college nutrition science course as an intervention to prevent weight gain in female college freshmen.

The objective of this study was to test the hypothesis that a nutrition course that stresses fundamental principles of human physiology, energy metabolism, and genetics helps prevent weight gain during the first 16 months of college life. A randomized control trial was conducted from January 1997 to May 1998 using volunteers. Forty female college freshmen participated in the intervention (college course, n = 21) and control (no course, n = 19) groups. The intervention was a one-semester nutrition science college course. Body weight, nutrient intakes, and knowledge were measured at baseline, the end of the intervention (4 months from baseline), and 1 year later (16 months from baseline). Statistical analysis was conducted using a repeated-measure analysis of variance. Higher Body Mass Index (BMI) students (BMI > 24) in the intervention group (n = 11) reported lower fat (p =.04), protein (p =.03), and carbohydrate (p =.008) intakes compared with the higher BMI students in the control group (n = 6). Dietary changes reported by the higher BMI intervention students were associated with the maintenance of baseline body weight for 1 year in contrast with the higher BMI control students who gained 9.2 6.8 kg (p =.012). The findings suggest that nutrition education emphasizing human physiology and energy metabolism is an effective strategy to prevent weight gain in at-risk college students.
