内容：健康的饮食和规律的身体活动赋予许多健康的好处，但这些行为的流行率是相对low.Background：成本效益的策略，需要增加健康饮食和体力活动的population.Design：一个随机对照试验，在2006年进行的，一个为期16周的电子邮件程序，提供个性化定制的，小步的目标，一个个人主页与提示，教育材料;设置/人群：一家大型医疗机构的行政办公室的787名员工自愿参加。主要结果测量：自我报告的总体力活动、中度体力活动（VPA）、剧烈体力活动（VPA）、步行、久坐行为、与对照组相比，干预组的水果和蔬菜、饱和脂肪和反式脂肪以及添加糖的摄入量。在意向治疗分析中（2007年和2008年进行），将后续问卷的无应答者的变化设置为零，与对照组相比，干预组报告MPA增加28.0分钟/周（min/wk）（SE=7.4，p=0.0002）; VPA增加12.5分钟/wk（SE=5.7，p=0.03）;步行增加21.5分钟/wk（SE=5.5，p=0.0003）。饱和脂肪和反式脂肪的摄入量（克/天[g/天]）下降（分别为β =-0.95，SE=0.36，p=0.01; β =-0.29，SE=0.12，p=0.02）。水果和蔬菜的消费量显著增加（p=0.03），添加糖的消费量略有下降（p=0.08）。最大的变化是在基线时不符合行为建议的参与者（相对于对照组，MPA增加55.4分钟/周，反式脂肪减少1.15克/天）。干预组和对照组之间的差异仍然观察4个月后，干预endos.Conclusions：ALIVE是一个有效的计划，为实现显着改善饮食和体力活动。试验注册：NCT 00607009。(Am J Prev Med 2009;36（6）：475-483）（C）2009年美国预防医学杂志
Context: Healthy diets and regular physical activity confer many health benefits, but the prevalence of these behaviors is relatively low.Background: Cost-effective strategies are needed to increase healthy eating and physical activity in the population.Design: An RCT, conducted in 2006, of a 16-week e-mail program offered individually tailored, small-step goals; a personal homepage with tips; educational materials; and tracking and simulation tools.Setting/population: Seven hundred eighty-seven employees in the administrative offices of a large healthcare organization volunteered to participate.Main outcome measures: Changes were self-reported for total physical activity; moderate physical activity (VPA); vigorous physical activity (VPA); walking; sedentary behavior; and intake of fruits and vegetables, saturated and trans fats, and added sugars in the intervention group compared to the control group.Results: In intent-to-treat analyses (conducted in 2007 and 2008) that set change in nonresponders to the follow-up questionnaire to zero, the intervention group reported increases of 28.0 tninutes/week (min/wk) of MPA (SE=7.4, p=0.0002); 12.5 min/wk of VPA (SE=5.7, p=0.03); and 21.5 min/wk of walking (SE=5.5, p=0.0003) relative to the control group. Intake of both saturated and trans fats (grams/day [g/day]) declined (beta=-0.95, SE=0.36, p=0.01; beta=-0.29, SE=0.12, p=0.02, respectively). The consumption of fruits and vegetables increased significantly (p=0.03), and the consumption of added sugars decreased marginally (p=0.08). The largest changes were in participants who did not meet behavioral recommendations at baseline (increase of 55.4 min/wk of MPA and decrease of 1.15 g/day of trans fats, relative to the control group). Differences between the intervention and control groups were still observed 4 months after the intervention ended.Conclusions: ALIVE is an effective program for achieving significant improvement in diet and physical activity.Trial registration: NCT00607009.
