The impact of perceived stress on US millennials' external and emotional eating behavior

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.
