Purpose

The purpose of this paper is to identify the relationship between Millennials' perceived stress and their external and emotional eating behaviors. Furthermore, the moderating effect of nutritional knowledge on the relationship between perceived stress and emotional eating and perceived stress and external eating of US Millennials was tested.

Design/methodology/approach

Data was collected from 649 Millennials between the ages of 18 and 35 in the United States, and structural equation modeling (SEM) was performed to test the study hypotheses.

Findings

This study extends the literature and provides further insights into the relationship between US Millennials' eating behavior and stress factors. Perceived stress positively influenced Millennials' emotional and external eating behavior, and nutritional knowledge significantly moderated the relationships between perceived stress and emotional eating and perceived stress and external eating.

Research limitations/implications

First, data was collected from Millennials living in the United States. Second, not all of the predictors, save one (perceived stress), were selected and hypothesized as predictors of Millennials' eating behavior. The paper provides the essential psychological elements of US Millennials' eating behavior.

Originality/value

If unbalanced eating and obesity are the result of negative psychological factors, the recommended diet models or physical exercise by themselves may be less effective at combating obesity and related health issues. This is because stress was found to be a highly significant reason for unbalanced eating, new and more practical stress coping strategies are needed to moderate unbalanced eating behavior.

感知压力对美国千禧一代的外部和情绪饮食行为的影响

目的

本文的目的是确定千禧一代的感知压力与其外在和情感进食行为之间的关系。此外，测试了营养知识对美国千禧一代的感知压力和情绪饮食与感知压力和外部饮食之间关系的调节作用。

设计/方法/方法

数据收集自美国18至35岁的649个千禧一代，并进行了结构方程模型（SEM）来检验研究假设。

发现

这项研究扩展了文献范围，并为美国千禧一代的饮食行为与压力因素之间的关系提供了进一步的见解。知觉压力对千禧一代的情绪和外来饮食行为产生积极影响，营养知识显着缓解了知觉压力和情绪饮食与知觉压力和外来饮食之间的关系。

研究局限/意义

首先，从居住在美国的千禧一代收集数据。其次，并非所有预测指标，只有一个（感知到的压力），都被选择并假设为千禧一代饮食行为的预测指标。本文提供了美国千禧一代饮食行为的基本心理要素。

创意/价值

如果饮食不平衡和肥胖是负面的心理因素造成的，则建议的饮食模型或体育锻炼本身在对抗肥胖和相关健康问题上可能不太有效。这是因为发现压力是饮食不均衡的重要原因，需要新的，更实际的压力应对策略来缓解饮食不均衡的行为。
