ABSTRACT
OBJECTIVE:
To explore the impact of the dietary patterns of truck drivers on their driving behaviours and the mediation effect of fatigue between these factors.METHODS:
A sample of 389 male truck drivers from a transport company in Suzhou, China completed the Food Frequency Questionnaire (FFQ), the Multidimensional Fatigue Inventory (MFI), the Positive Driver Behaviours Scale (PDBS) and the Driver Behaviour Questionnaire (DBQ). The associations among dietary patterns, fatigue and driving behaviour were examined using pathway analysis.RESULTS:
Four dietary patterns were identified based on principal componentanalysis:
animal-derived foods, staple foods, snacks and vegetables. The pathway analysis showed that the vegetable-rich pattern had a direct positive impact on positive driving behaviour (ß=0.211, p<0.001); the animal-derived pattern had a direct positive impact on errors (ß=0.094, p<0.05) and ordinary violations (ß=0.071, p<0.05); the snacks pattern had a direct negative impact on positive driving behaviour (ß=-0.191, p<0.001); fatigue mediated the effect of dietary patterns on driving behaviours (p<0.001); and the staple foods had an indirect effect on driving behaviours.CONCLUSIONS:
Overall, the driving behaviours of truck drivers are correlated with their dietary patterns. Drivers who preferred vegetables and staple foods had more positive driving behaviour, while the animal-derived food and snack patterns were related to dangerous driving behaviour. The experience of fatigue could explained the underlying mechanism between these factors.Palavras-chave
