对1999年至2009年3月发表的关于工作场所体力活动或营养干预的研究进行了全面的文献搜索。这项搜索确定了29项相关研究。根据干预措施所依据的理论框架(例如，教育、认知行为、增强动机、社会影响、锻炼)对干预措施进行分组。计算加权Cohens d效应大小、重叠百分比统计量、可信区间和失效安全NS。大多数理论方法都与小效应有关。然而，一些使用动机增强的干预措施被发现有很大的效果。对于集中于一种健康行为的研究和随机对照试验，效果的大小更大。工作场所是一个适宜对员工的身体活动、营养和健康做出适度改变的环境。有必要进行进一步的研究，以确定这些变化能否长期保持。
A comprehensive search of the literature for studies examining physical activity or nutrition interventions in the workplace, published between 1999 and March 2009, was conducted. This search identified 29 relevant studies. Interventions were grouped according to the theoretical framework on which the interventions were based (e.g. education, cognitive-behavioural, motivation enhancement, social influence, exercise). Weighted Cohens d effect sizes, percentage overlap statistics, confidence intervals and fail safe Ns were calculated. Most theoretical approaches were associated with small effects. However, large effects were found for some measures of interventions using motivation enhancement. Effect sizes were larger for studies focusing on one health behaviour and for randomized controlled trials. The workplace is a suitable environment for making modest changes in the physical activity, nutrition and health of employees. Further research is necessary to determine whether these changes can be maintained in the long term.
