冲动与不健康的食物选择有关。在食物环境中的轻推干预可能对高冲动性的人特别有帮助。研究特质、选择和行动冲动是否与基于工作场所的轻推干预改善饮食和体重的有效性相关。这是对ChooseWell 365的487名参与者的计划二次分析，ChooseWell 365是一项随机对照试验，旨在测试为期12个月的推动干预，以改善医院员工的自助餐厅购买。用Barratt冲动量表测量特质冲动性。选择和行动冲动分别与延迟折扣和反应抑制任务进行了评估。为每个测量生成三分位数。多变量回归模型研究了冲动性与12个月内自助餐厅购买[健康购买评分（HPS）]，饮食摄入[健康饮食指数-2015（HEI）评分]和12个月时测量的体重指数（BMI）的相关性。互动条款测试的冲动水平的干预效果的差异。具有较高特质（p= 0.02）和选择（p<0.001）冲动性的参与者的基线HPS低于冲动性较低的参与者。所有冲动性水平的员工都增加了健康饮食，但在12个月内，更高的特质冲动性与HPS的较小增加相关（p= .03）。在最高动作冲动三分位数中，干预组与对照组受试者相比，12个月BMI增加较少（0.3 vs 0.5 kg/m2; p-相互作用= 0.04）。特质或选择冲动性没有交互作用。工作场所的助推干预改善了所有冲动性水平的员工的食物选择，并削弱了那些具有较高行动冲动性的员工的体重增加。
Impulsivity is associated with unhealthy food choices. Nudge interventions in the food environment may be particularly helpful for individuals with high impulsivity. To examine if trait, choice, and action impulsivity were associated with the effectiveness of a workplace-based nudge intervention to improve diet and weight. This was a planned secondary analysis of 487 participants of ChooseWell 365, a randomized controlled trial that tested a 12-month nudge intervention to improve cafeteria purchases among hospital employees. Trait impulsivity was measured with the Barratt Impulsiveness Scale. Choice and action impulsivity were assessed with delay discounting and response inhibition tasks, respectively. Tertiles were generated for each measure. Multivariable regression models examined the association of impulsivity with cafeteria purchases [Healthy Purchasing Score (HPS)] over 12 months, dietary intake [Healthy Eating Index-2015 (HEI) score], and body mass index (BMI) measured at 12 months. Interaction terms tested differences in intervention effect by level of impulsivity. Participants with higher trait (p= .02) and choice (p< .001) impulsivity had lower baseline HPS than those with lower impulsivity. Employees of all impulsivity levels increased healthy eating, but higher trait impulsivity was associated with smaller increase in HPS over 12 months (p= .03). In the highest action impulsivity tertile, 12-month BMI increased less for intervention vs. control participants (0.3 vs. 0.5 kg/m2;p-interaction = .04). There were no interaction effects for trait or choice impulsivity. A workplace nudge intervention improved food choices among employees of all impulsivity levels and attenuated weight gain in those with higher action impulsivity.
