人体成分分析在住院精神疾病患者营养诊断中的应用研究

The study of application of body composition analysis in nutritional diagnosis of hospitalized mental patients

目的探讨人体成分分析在住院精神疾病患者营养诊断中的作用。方法纳入住院精神疾病患者100例为病例组,同时招募与病例组年龄、性别等相匹配的健康者100例为对照组。利用生物电阻抗技术进行人体成分检测,并对比分析各组的检测结果。结果病例组男性与女性的身体质量指数(21.05 vs.24.30;18.40 vs.23.30)、蛋白质(9.40 vs.10.70;6.85 vs.7.95)、无机盐(3.02 vs.3.74;2.48 vs.2.94)、骨矿物质含量(2.46 vs.3.10;2.05 vs.2.47)、上臂围度(28.85 vs.31.10;25.05 vs.28.60)、相位角(4.95 vs.6.00;4.70 vs.5.19)、身体细胞量(24.65 vs.35.45;24.50 vs.26.45)、细胞内水分比率(0.61 vs.0.62;0.61 vs.0.62)、去脂体重(38.25 vs.53.95;38.05 vs.40.75)、骨骼肌质量(20.45 vs.30.30;20.30 vs.22.10)、无脂肪质量指数(14.39 vs.18.80;14.57 vs.15.70)、骨骼肌质量指数(7.58 vs.10.50;7.78 vs.8.55)及身体脂肪量(11.45 vs.15.60;12.60 vs.17.95)分别低于对照组(P<0.05),而细胞外水分比率(0.39 vs.0.38;0.39 vs.0.38)高于对照组(P<0.05);病例组与对照组中,男性与女性的相位角与细胞内水分、细胞内外水分比率、蛋白质、骨骼肌质量及身体细胞量均呈正相关(P<0.05)。结论病例组男性与女性的人体成分分析结果较对照组差,因此可用于住院精神疾病患者的营养诊断。

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.
