This randomised controlled trial verified the efficacy of an implementation intentions intervention ( n = 24) to promote fruit and vegetable consumption among childbearing age women at risk for gestational diabetes mellitus against a control condition based on the question-behaviour effect ( n = 26). There was only a significant time effect ( F(2,85) = 5.69, p = 0.0048). Both groups increased their vegetable consumption compared to baseline at 3 months ( p = 0.0022) and 6 months ( p = 0.0042). There were no significant effects on weight, waist circumference and blood glucose levels. Implementation intentions and the question-behaviour effect appear to be effective behaviour change techniques to promote vegetable intake among this high-risk population.
这项随机对照试验验证了实施意向干预（n=24）在促进有妊娠糖尿病风险的育龄妇女食用水果和蔬菜方面的功效，该干预与基于问题-行为效应的对照条件（n=26）进行了对比。仅观察到时间效应具有显著性（F(2,85)=5.69，p=0.0048）。与基线相比，两组在 3 个月（p=0.0022）和 6 个月（p=0.0042）时的蔬菜摄入量均有所增加。体重、腰围和血糖水平均无显著影响。实施意向和问题-行为效应似乎是促进高危人群蔬菜摄入量的有效行为改变技术。
