To test the effectiveness of a 15-month intervention for reducing sugar-sweetened beverage (SSB) intake among college students and assess fruit and vegetable (F/V) intake and physical activity (PA) habits and their relationship to SSB intake.
Randomized, controlled study.
A total of 156 college students (aged 18-24 years) from a Kansas university, mostly female (72%), white (89%), and freshmen (51%).
Two-staged intervention included participants receiving: (1) 3 weekly stage-tailored messages on healthful behaviors for 10 weeks; and (2) 3 monthly stage-tailored messages and 1 monthly e-mail encouraging a visit to the portal page, after the 3-month physical assessment.
MAIN OUTCOME MEASURE(S): Stages of change for PA and F/V intake, self-reported PA scores, self-reported F/V intake, and SSB intake habits.
Generalized linear mixed models and linear regression models were used to test changes and associations among outcome measures.
No significant decrease occurred in SSB consumption (P > .05) among intervention participants. Both control and intervention groups recorded low F/V intake and moderate PA scores.
Low F/V intake and high SSB intake evident among study participants may pose risk for unwanted weight gain and obesity-related conditions. Furthermore, college campuses can continue to support an environment conducive for being physically active, while promoting healthy eating behaviors.
测试一项为期 15 个月的干预措施在减少大学生含糖饮料（SSB）摄入量方面的有效性，并评估水果和蔬菜（F/V）摄入量和体育活动（PA）习惯及其与 SSB 摄入量的关系。
随机对照研究。
来自堪萨斯州一所大学的 156 名大学生（年龄在 18-24 岁之间），大多数为女性（72%）、白人（89%）和新生（51%）。
两阶段干预包括参与者接受：（1）10 周内每周 3 次针对健康行为的阶段定制信息；（2）3 个月身体评估后，每月 3 次阶段定制信息和 1 次每月电子邮件，鼓励访问门户页面。
PA 和 F/V 摄入量的变化阶段、自我报告的 PA 评分、自我报告的 F/V 摄入量和 SSB 摄入习惯。
使用广义线性混合模型和线性回归模型来测试结果测量之间的变化和关联。
干预组 SSB 消费（P>.05）没有显著下降。对照组和干预组的 F/V 摄入量均较低，PA 评分中等。
研究参与者中明显的低 F/V 摄入和高 SSB 摄入可能会导致不必要的体重增加和肥胖相关疾病的风险。此外，大学校园可以继续支持有利于身体活跃的环境，同时促进健康的饮食习惯。
