Abstract: Objective To investigate the role of body composition analysis in the nutritional diagnosis of hospitalized mental patients. 
Methods A total of 100 hospitalized mental patients were enrolled as the case group, and 100 age- and gender-matched healthy individuals were recruited as the control group. Bioelectrical impedance analysis was used to detect body composition, and the test results of each group were compared. 
Results The body mass index (BMI) (21.05 vs. 24.30; 18.40 vs. 23.30), protein (9.40 vs. 10.70; 6.85 vs. 7.95), minerals (3.02 vs. 3.74; 2.48 vs. 2.94), bone mineral content (2.46 vs. 3.10; 2.05 vs. 2.47), arm circumference (28.85 vs. 31.10; 25.05 vs. 28.60), phase angle (4.95 vs. 6.00; 4.70 vs. 5.19), body cell mass (24.65 vs. 35.45; 24.50 vs. 26.45), intracellular water (ICW) ratio (0.61 vs. 0.62; 0.61 vs. 0.62), fat-free mass (FFM) (38.25 vs. 53.95; 38.05 vs. 40.75), skeletal muscle mass (20.45 vs. 30.30; 20.30 vs. 22.10), FFM index (14.39 vs. 18.80; 14.57 vs. 15.70), skeletal muscle mass index (7.58 vs. 10.50; 7.78 vs. 8.55) and body fat mass (11.45 vs. 15.60; 12.60 vs. 17.95) in the case group were lower than those in the control group (P<0.05), while the extracellular water ratio (0.39 vs. 0.38; 0.39 vs. 0.38) was higher than that in the control group (P<0.05). In case and control groups, the phase angles of men and women were positively correlated with ICW, ICW ratio, protein, skeletal muscle mass and body cell mass (P<0.05). 
Conclusion The body composition analysis results of men and women in the case group are worse than those in the control group; therefore, it can be used for the nutritional diagnosis of hospitalized mental patients.
