首发精神分裂症患者体重偏瘦与认知功能的关系
|
Abstract:
目的：探讨首发精神分裂症患者偏瘦对认知功能的影响。方法：本研究纳入首发精神分裂症患者，按照BMI不同将其分为两组，对每一位患者的身高、体重、认知功能进行测评。结果：BMI与数字符号呈正相关，与连线测验A及连线测验B所用时间呈负相关；体重正常组数字符号、连线测验A及连线测验B的成绩好于体重偏瘦组。结论：BMI能够影响认知，体重偏瘦的首发精神分裂症患者认知功能低于体重正常组的患者，体重越瘦其认知功能越差。
Objective: The purpose of our study was to investigate the influence of underweight on cognitive function. Methods: The study recruited patients with first-episode schizophrenia, and they were divided into two groups according to BMI. The data of height, weight, and cognitive functions of the patients were collected. Results: There was a positive correlation between the BMI and Digit Symbol. There was a negative correlation between the BMI and Trail Making Test A and Trail Making Test B. Underweight patients with schizophrenia had significantly lower scores than the patients with normal weight on the Digit Symbol, Trail Making Test A and Trail Making Test B. Conclusion: Our study suggests that BMI can affect cognitive function; the cognitive function of the underweight patients is lower than the patients with normal weight; the lower the weight, the worse the cognitive function.
