OBJECTIVES
The relation between food insecurity (FI) and delay discounting (DD) and probability discounting (PD) for food and money was tested in women. In addition, discounting was tested as a variable that mediates the relation between obesity and FI.
METHOD
Women recruited from a community sample (N = 92) completed questionnaires. They completed the food choice questionnaire, the monetary choice questionnaire, measures for food and money probability discounting (which quantify sensitivity to risk aversion), and demographic measures.
RESULTS
Women with FI had higher rates of obesity and higher food DD compared to food-secure women. However, DD for money or probability discounting for food or money did not significantly differ between FI and food secure groups when controlling for significant covariates. Neither DD or PD significantly mediated the relation between FI and obesity.
CONCLUSIONS
These results suggest that FI is associated with greater impulsive food choice, but its association with other monetary discounting and probability discounting for food and money appears contingent upon other demographic factors. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
目的
研究食物不安全感（FI）与延迟折扣（DD）和金钱及食物概率折扣（PD）在女性中的关系。此外，还测试了折扣作为肥胖与 FI 之间关系的中介变量的可能性。
方法
从社区样本中招募的女性（N=92）完成了问卷调查。她们完成了食物选择问卷、货币选择问卷、食物和金钱概率折扣的测量（量化风险规避的敏感性）以及人口统计学测量。
结果
与食物安全的女性相比，FI 女性的肥胖率更高，食物 DD 更高。然而，当控制重要协变量时，FI 和食物安全组之间的金钱 DD 或食物和金钱 PD 差异并不显著。DD 或 PD 均不能显著中介 FI 和肥胖之间的关系。
结论
这些结果表明，FI 与冲动性食物选择有关，但它与其他金钱折扣以及食物和金钱的概率折扣之间的关系似乎取决于其他人口统计学因素。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
