OBJECTIVE
Examine the effectiveness of the worksite-based weight gain prevention program Netherlands Heart Foundation-Netherlands Research program weight Gain prevention In Balance, with regard to behavioral changes and corresponding cognitive determinants.
METHODS
A nonrandomized pretest-repeated posttest control group design was applied in 12 worksites. Intervention groups received individual and environmental interventions, directed at physical activity and food intake. Measurements were executed at baseline and after 12 and 24 months.
RESULTS
Nearly all behaviors in the intervention group improved more than in the control group, even though improvements in behaviors were often too small to reach statistical significance. No positive intervention effects were observed for the cognitive factors.
CONCLUSION
Differential changes between the intervention and control group were observed for several important dietary and physical activity behaviors. Valuable information is gained regarding the implementation of weight gain prevention programs in worksites.
目的
检验基于工作场所的增重预防计划——荷兰心脏基金会-荷兰研究计划增重预防平衡计划在行为改变及其相应认知决定因素方面的有效性。
方法
采用非随机预测试-重复后测试对照组设计，在 12 个工作场所进行。干预组接受个体和环境干预，针对身体活动和食物摄入。在基线、12 个月和 24 个月时进行测量。
结果
干预组的几乎所有行为都比对照组改善更多，尽管行为改善通常太小，无法达到统计学意义。对于认知因素，没有观察到积极的干预效果。
结论
干预组和对照组在一些重要的饮食和身体活动行为方面观察到了差异变化。这为在工作场所实施增重预防计划提供了有价值的信息。
