目标.本文介绍了美国迄今为止最大的工作场所癌症预防和控制试验的行为结果。工作井试验采用随机配对评价设计，以工作现场为分配和分析单位。该研究在111个工作场所（n = 28 000名工人）进行。通过比较干预和对照工作场所的变化，评估干预的效果，如基线和随访时的横断面调查所测量的。为期2年的干预针对个人和工作场所的环境。从脂肪消耗中获得的能量百分比净减少0.37个百分点（P = 0.033），纤维密度净增加0.13 g/1000 kcal（P = 0.056），水果和蔬菜摄入量平均增加0.18份/天（P = 0.0001）。烟草使用的变化是在预期的方向，但并不显着。营养方面的差异很大，但很小。在试验范围内的吸烟结局中观察到积极趋势，但无显著结果。观察到的净差异很小：由于目标行为的实质性长期变化。
Objectives. This paper presents the behavioral results of the Working well Trial, the largest US work site cancer prevention and control trial to date.Methods. The Working Well Trial used a randomized, matched: pair evaluation design, with the work site as the unit of assignment and analysis. The study was conducted in 111 work sites (n = 28 000 workers). The effects of the intervention were evaluated by comparing changes in intervention and control work sites, as measured in cross-sectional surveys at baseline and follow-up. The 2-year intervention targeted both individuals and the work-site environment.Results. There occurred a net reduction in the percentage of energy obtained from fat consumption of 0.37 percentage points (P = .033), a net increase in fiber densities of 0.13 g/1000 kcal (P = .056), and an average increase in fruit and vegetable intake of 0.18 servings per day (P = .0001). Changes in tobacco use were in the desired direction but were not significant.Conclusions. Significant but small differences were observed for nutrition. Positive trends, but no significant results, were observed in trial-wide smoking outcomes. The observed net differences were small :owing to the substantial secular changes in target behaviors.
