粮食不安全被定义为无法预测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）和肥胖症相关联。研究表明，延迟折扣，一种倾向于立即而不是延迟奖励的行为经济学措施，与较高的BMI有关，并缓和了收入和粮食不安全之间的关系。在这项研究的基础上，我们使用回归模型来测试是否延迟折扣，考虑未来的后果，和感知的压力是在313名母亲的食物不安全的BMI关系的非时间介质，控制人口统计学变量。第二个目的是复制延迟折扣缓和低收入和高度粮食不安全之间的关系的研究结果。结果表明，低收入与更高的粮食不安全有关，更高的粮食不安全与更高的BMI有关。延迟折扣是唯一的变量，是间接相关的两个路径的粮食不安全，体重指数的关系。延迟折扣对低收入-食物不安全-肥胖关系的解释力为22.2%，总模型解释力为38.0%。低收入与粮食不安全之间的关系因延迟折扣而有所缓和。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和帮助粮食不安全的人减轻超重的新目标。试验注册。本试验注册号为NCT 02873715。
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.
