Although experts claim that computer-tailored interventions provided over the Internet have great potential to promote health behavior change, few studies have tested the efficacy of computer-tailored lifestyle interventions online-delivered over the Internet.
To evaluate the short-term (1 month) efficacy of an Internet-delivered, computer-tailored lifestyle intervention targeting saturated fat intake, physical activity (PA), and smoking cessation, and to evaluate exposure to the intervention.
A pretest-posttest randomized controlled trial with an intervention group and a no intervention waiting list control group was conducted. Self-reported behavior and determinants were assessed at baseline and 1 month follow-up. Exposure to the intervention was monitored through server registrations. The data were analyzed using multiple linear and logistic regression analysis.
The intervention resulted in a significantly lower self-reported saturated fat intake (b = -0.76, p < 0.01) and a higher likelihood of meeting the PA guidelines among respondents who were insufficiently active at baseline (OR = 1.34, 95%CI = 1.001-1.80). No significant intervention effects were found for self-reported smoking status. Of the participants, 81% actually visited the website.
The Internet-delivered, computer-tailored lifestyle intervention was effective in reducing self-reported saturated fat intake and in increasing self-reported PA among participants who completed the study.
尽管专家声称通过互联网提供的计算机定制干预措施在促进健康行为改变方面具有巨大潜力，但很少有研究测试过通过互联网在线提供的计算机定制生活方式干预措施的效果。
评估针对饱和脂肪摄入量、身体活动（PA）和戒烟的互联网提供的计算机定制生活方式干预措施的短期（1个月）效果，并评估对该干预措施的接触情况。
进行了一项前测-后测随机对照试验，设有干预组和无干预等待名单对照组。在基线和1个月随访时评估自我报告的行为和决定因素。通过服务器注册监测对干预措施的接触情况。使用多元线性和逻辑回归分析对数据进行分析。
干预导致自我报告的饱和脂肪摄入量显著降低（b = -0.76，p < 0.01），并且在基线时身体活动不足的受访者中达到PA指南的可能性更高（OR = 1.34，95%CI = 1.001 - 1.80）。对于自我报告的吸烟状况，未发现显著的干预效果。在参与者中，81%实际访问了该网站。
对于完成研究的参与者，通过互联网提供的计算机定制生活方式干预措施在降低自我报告的饱和脂肪摄入量和增加自我报告的PA方面是有效的。
