“…Compared to the general population, certain occupational groups exhibit greater incidences of poor mental health [ 29 ]. While several studies, both domestic and foreign, have examined mental health problems among different occupational groups, most have focused on ethnic majorities [ 30 , 31 , 32 ] or a limited number of occupational types, such as healthcare workers, teachers, soldiers, students, pilots, and athletes [ 33 , 34 , 35 , 36 , 37 , 38 , 39 ].
