To report findings from Treatwell 5-a-Day process tracking.
Worksites were randomly assigned to a minimal intervention control, worksite-only condition, or worksite-plus-family condition.
Twenty-two small community health centers in Massachusetts.
Employees of the community health centers.
Both intervention conditions included the formation of employee advisory boards; activities such as nutrition discussions and taste tests targeting individual behavior change; and point-of-purchase labeling as an environmental strategy. Worksite-plus-family sites incorporated activities such as family contests, campaigns, and picnics.
Documentation of the number and type of activities for extent of implementation; number of participants in activities for reach; program awareness and participation from the follow-up employee survey (n = 1306, representing 76% [range, 56%-100%] of the sample); change in fruit and vegetable consumption from a comparison between the follow-up and baseline surveys (n = 1359, representing 87% [range, 75%-100%] of the sample).
A higher number of activities per employee was significantly correlated with greater program awareness (.68; p = .006) and greater change in fruit and vegetable consumption (.55; p = .04). Greater participation in activities was significantly correlated with greater awareness (.67; p = .007), higher participation (.61; p = .02), and increase in fruit and vegetable consumption. (.55; p = .04).
These results provide quantitative indicators of a dose-response relationship between the number of intervention activities per employee and higher percentage of employee participation and observed increases in fruit and vegetable consumption.
报告“每日五蔬果”项目过程追踪的结果。
工作场所被随机分配至最低限度干预对照组、仅工作场所干预组或工作场所加家庭干预组。
马萨诸塞州的22个小型社区健康中心。
社区健康中心的员工。
两个干预组均包括成立员工咨询委员会；开展针对个人行为改变的营养讨论和口味测试等活动；以及使用购买点标签作为环境策略。工作场所加家庭干预组还开展了家庭竞赛、活动和野餐等活动。
记录实施活动的数量和类型以评估实施程度；记录活动参与者数量以评估覆盖范围；通过后续员工调查（n = 1306，占样本的76%[范围为56%-100%]）评估项目知晓度和参与度；通过对比后续调查和基线调查评估水果和蔬菜摄入量的变化（n = 1359，占样本的87%[范围为75%-100%]）。
每名员工参与的活动数量越多，与更高的项目知晓度（.68；p = .006）以及水果和蔬菜摄入量的更大变化（.55；p = .04）显著相关。更多地参与活动与更高的知晓度（.67；p = .007）、更高的参与度（.61；p = .02）以及水果和蔬菜摄入量的增加（.55；p = .04）显著相关。
这些结果提供了定量指标，表明每名员工参与的干预活动数量与更高的员工参与率以及观察到的水果和蔬菜摄入量增加之间存在剂量反应关系。
