Effects of dietary patterns on driving behaviours among professional truck drivers: the mediating effect of fatigue
In their study, Ge et al. (2021) set out to investigate the effect that truck driver’s dietary habits, had on their driving behaviors, and whether fatigue experienced by truck drivers had any contributory impact. Data from the study participants (389 male truck drivers) was collected using the Food Frequency Questionnaire (FFQ), the Multidimensional Fatigue Inventory (MFI), and the Positive Driver Behaviors Scale (PDBS) and the Driver Behavior Questionnaire (DBQ). The results highlighted four dietary patterns adopted by truck drivers: animal-derived foods, staple foods, snacks, and vegetables. Data analysis showed that the vegetable-rich pattern had a direct positive impact on driving habits, whereas the animal-derived pattern led to more driving mistakes and traffic infractions. The snacks dietary pattern was linked to negative driving behavior. Staple foods, on the other hand, had an indirect positive effect on driving behavior. Furthermore, the results demonstrated that the level of fatigue experienced by drivers was found to influence the choice of dietary pattern, and subsequently, driving behavior.
