To determine the impact of My Student Body (MSB)-Nutrition, an Internet-based obesity prevention program for college students.
Three hundred and twenty ethnically diverse undergraduate students were randomly assigned to 1 of 3 conditions: MSB-Nutrition program, an on-campus weight management course, and a comparison group.
Students completed baseline and follow-up surveys regarding their nutrition and physical activity behaviors, self-efficacy, stress, attitudes, and body weight.
Compared with the on-campus course and a comparison group, the MSB-Nutrition program increased fruit and vegetable consumption, reduced stress, and increased fruit and vegetable self-efficacy but had no significant effect on students' exercise self-efficacy, exercise behavior, or weight loss.
The MSB-Nutrition program was effective in changing students' nutrition behaviors but had no effect on physical activity behaviors or weight loss. Suggestions for improving Internet-based interventions aimed at decreasing obesity rates among college students are offered.
确定基于互联网的大学生肥胖预防计划“我的学生群体（MSB）-营养”的影响。
320 名不同种族的本科生被随机分配到以下 3 种条件之一：MSB-营养计划、校内体重管理课程和对照组。
学生完成了关于他们的营养和身体活动行为、自我效能、压力、态度和体重的基线和随访调查。
与校内课程和对照组相比，MSB-营养计划增加了水果和蔬菜的摄入量，降低了压力，提高了水果和蔬菜的自我效能，但对学生的运动自我效能、运动行为或体重减轻没有显著影响。
MSB-营养计划在改变学生的营养行为方面是有效的，但对身体活动行为或体重减轻没有影响。提供了有关改进旨在降低大学生肥胖率的基于互联网的干预措施的建议。
