Abstract: Objective This study aimed to compare the relationships between chronotype and nutrition attitudes, mood, and sleep quality among police officers and teachers with different work schedules. Materials and Methods This cross-sectional, comparative study was conducted with 176 participants (104 teachers and 72 police officers). Participants completed an online survey including demographic data, dietary habits, the Attitude Scale for Healthy Nutrition, Morningness–Eveningness Questionnaire, Depression Anxiety Stress Scale, and Pittsburgh Sleep Quality Index. Results Police officers' eating habits were more affected by their work schedule than those of teachers (p < 0.05). In terms of chronotype, the majority of police officers were intermediate types, while the majority of teachers were morning types (p < 0.05). Teachers reported better sleep quality than police officers, although the difference did not reach significance (p > 0.05). Evening- and intermediate-type participants had higher depression, anxiety, and stress scores than morning types (2- to 4-fold higher for teachers; 5- to 6-fold higher for police officers). In addition, evening-type police officers had significantly poorer sleep quality than morning types. Conclusion These findings suggest that the intermediate and evening chronotypes may be associated with a greater negative impact on mood and sleep quality, particularly in rotating shift workers.
