摘要

粮食不安全被定义为无法预测地获得可能无法满足一个人营养需求的食物,与较高的BMI(kg/m2)和肥胖有着矛盾的联系。研究表明,延迟折扣是一种行为经济学指标,衡量人们对即时而非延迟奖励的偏好,它与较高的BMI有关,并调节收入和粮食不安全之间的关系。基于这项研究,我们使用回归模型来测试313名母亲在控制人口统计学变量的情况下,延迟折扣、对未来后果的考虑和感知压力是否是粮食不安全BMI关系的主要中介因素。第二个目的是复制延迟贴现调节低收入和高度粮食不安全之间关系的发现。结果表明,低收入与更高的粮食不安全感有关,而更高的食品不安全感与更高BMI有关。延迟折扣是唯一与粮食不安全BMI关系的两条路径间接相关的变量。延迟折扣占低收入粮食不安全-肥胖关系方差的22.2%,总模型占方差的38.0%。延迟贴现缓和了低收入与粮食不安全之间的关系。这些数据表明,延迟折扣是粮食不安全和高BMI之间关系的潜在中介,这表明未来减少折扣可能是减少粮食不安全的一个新目标,并帮助粮食不安全人群减少超重。试用注册。本试验注册号为NCT02873715。

Delay Discounting and the Income-Food Insecurity-Obesity Paradox in Mothers.

Delay Discounting and the Income-Food Insecurity-Obesity Paradox in Mothers.

Food insecurity, defined as unpredictable access to food that may not meet a person's nutritional needs, is paradoxically associated with higher BMI (kg/m2) and obesity. Research has shown delay discounting, a behavioral economic measure of the preference for immediate rather than delayed rewards, is related to higher BMI, and moderates the relationship between income and food insecurity. Based on this research, we used regression models to test whether delay discounting, consideration of future consequences, and perceived stress were atemporal mediators of the food insecurity-BMI relation in 313 mothers, controlling for demographic variables. A secondary aim was to replicate the finding that delay discounting moderates the relationship between low income and high food insecurity. Results showed that low income was associated with higher food insecurity, and higher food insecurity was associated with higher BMI. Delay discounting was the only variable that was indirectly related to both paths of the food-insecurity-BMI relation. Delay discounting accounted for 22.2% of the variance in the low-income-food insecurity-obesity relation, and the total model accounted for 38.0% of the variance. The relation between low income and food insecurity was moderated by delay discounting. These data suggest that delay discounting is a potential mediator of the relationship between food insecurity and high BMI, which suggests reducing discounting in the future could be a novel target to reduce food insecurity and help people with food insecurity to reduce their excess body weight. Trial Registration. This trial is registered with NCT02873715.
