背景许多雇主现在都在提供健康计划，帮助员工改变饮食和锻炼行为。改善健康结果和降低成本将取决于员工是否在一段时间内保持生活方式的改变和保持健康的体重。PURPOSE为了确定在为期10周的工作场所锻炼和营养计划后立即进行9个月的维持干预是否能防止在计划期间体重重新下降。设计。设置/PARTICIPANTS 2008年，来自24个团队的330名员工在一家大型医院的工作地点完成了为期10周的锻炼和营养计划，并由团队随机分配到维持或控制(日常护理)9个月。干预措施通过一个网站提供互联网支持，以设定目标和自我监测体重和锻炼，并提供最低限度的个人支持。MAIN结果测量体重、减重百分比、减重百分比与基线相比，一年内花在体力活动上的时间，以及食用水果/蔬菜、高脂肪食物和含糖食物的频率。2010年完成了为期一年的随访，并于2011年进行了数据分析。结果1年，238名受试者(72%)完成了随访评估。平均基线BMI为27.6，在干预组和对照组之间没有差异。与基线相比，两组患者在为期10周的计划中体重均有所下降，并在1年内保持了65%的体重下降(p<；0.001)。在为期10周的计划结束时，两组之间的体重减轻没有差异(X组相互作用时为4.8磅对4.3磅，p=0.53)，或在1年维持结束时(X组相互作用时为3.4磅对2.5磅，p=0.40)。所有受试者在1年后的体力活动和营养(增加水果/蔬菜和减少脂肪和糖的摄入量)方面都有所改善，但不同组之间没有差异。结论为期10周的强化工作场所锻炼和营养计划在1年后导致中等程度的体重减轻和饮食和锻炼行为的改善，但在10周计划之后立即进行的基于互联网的维护计划并没有改善这些结果。
BACKGROUNDMany employers are now providing wellness programs to help employees make changes in diet and exercise behaviors. Improving health outcomes and reducing costs will depend on whether employees sustain lifestyle changes and maintain a healthy weight over time.PURPOSETo determine if a 9-month maintenance intervention immediately following a 10-week worksite exercise and nutrition program would prevent regain of the weight lost during the program.DESIGNRCT.SETTING/PARTICIPANTSIn 2008, a total of 330 employees from 24 teams completed a 10-week exercise and nutrition program at a large hospital worksite and were randomized by team to maintenance or control (usual care) for 9 months.INTERVENTIONInternet support with a website for goal-setting and self-monitoring of weight and exercise plus minimal personal support.MAIN OUTCOME MEASURESWeight loss, percentage weight loss, time spent in physical activity, and frequency of consumption of fruits/vegetables, fatty foods, and sugary foods at 1 year compared to baseline. One-year follow-up was completed in 2010, and data were analyzed in 2011.RESULTSAt 1 year, 238 subjects (72%) completed follow-up assessments. Mean baseline BMI was 27.6 and did not differ between intervention and control. Compared to baseline, both groups lost weight during the 10-week program and maintained 65% of weight loss at 1 year (p<0.001). There was no difference in weight loss between groups at the end of the 10-week program (4.8 lbs vs 4.3 lbs, p=0.53 for group X time interaction) or end of maintenance at 1 year (3.4 lbs vs 2.5 lbs, p=0.40 for group X time interaction). All subjects had improvements in physical activity and nutrition (increased fruits/vegetables and decreased fat and sugar intake) at 1 year but did not differ by group.CONCLUSIONSAn intensive 10-week team-based worksite exercise and nutrition program resulted in moderate weight loss and improvements in diet and exercise behaviors at 1 year, but an Internet-based maintenance program immediately following the 10-week program did not improve these outcomes.TRIAL REGISTRATIONThis study is registered at clinicaltrials.govNCT00707577.
