This study investigated the influence of chronotype behaviour on body mass index (BMI) and associated demographic factors among two distinct groups; a control group of daytime workers and a shift worker group. The control group, comprising fixed daytime workers, showed significant gender differences in BMI and chronotype scores, with females exhibiting higher BMI and more pronounced chronotype effects than males. Marital status significantly influenced BMI and chronotype in married and unmarried subjects differently, with unmarried individuals displaying stronger chronotype associations. A positive correlation between BMI and chronotype scores was observed, suggesting interdependence between circadian preferences and body composition. Among shift workers, females demonstrated significant effects of gender on both BMI and chronotype, whereas males did not. Marital status impacted BMI significantly only in married shift workers. The correlation between BMI and chronotype was also significant in shift workers, reinforcing the relationship between circadian rhythm and metabolic factors. Mann-Whitney analyses revealed that BMI significantly affected shift workers, while chronotype significantly influenced control subjects. These findings underscore the complex interactions between chronobiological factors, work patterns, and metabolic health, highlighting the importance of chronotype in understanding health outcomes in both shift and daytime workers.
