Police officers may be at a higher risk of suffering from mental disorders (MDs) compared with other occupations. This study aimed to examine the physiological predictors of MDs among police officers in Indonesia. The mental health status of each participant was examined using a standardized Minnesota Multiphasic Personality Inventory (MMPI) tool and underwent several laboratory examinations including hematology, urine, serology, and electrocardiogram tests. A logistic regression was performed to calculate the odds ratio. Of the 4590 participants, 2.14% were diagnosed with MDs. The study found 19 physiological variables are potential predictors of MDs. In multivariate analysis adjusted for body mass index, sex, and age, the concentration of ketones, protein, and specific gravity in urine and the amount of lymphocyte in the blood are among important predictors of MDs. This suggests that carefully examining the results of urinalysis and hematology tests can help us detect early cases of MDs among police officers.
