常见精神障碍发病与空气负离子浓度的相关性

Relationship between common mental disorders and concentration of negative air ions

目的研究空气负离子浓度与常见精神障碍发病的相关性,探讨空气负离子浓度对常见精神障碍发病的影响。方法对中山市第三人民医院2010年6月-2017年5月入院的精神分裂症、精神发育迟滞和双相情感障碍患者的病历资料进行整理分析,将各病种月入院量与同期月平均空气负离子浓度进行相关分析。结果 Pearson相关分析显示,双相抑郁月入院量与月平均空气负离子浓度呈正相关(r=0.34,P<0.01),1月-12月月均空气负离子浓度分别为:353、336、419、564、658、729、700、665、637、512、393、479个/cm^3,对应月份双相抑郁月累积入院量分别为:37、20、36、38、55、31、29、41、44、38、26、37人次。结论双相抑郁在低浓度空气负离子时发病增多,高浓度时发病减少。

Objective To understand the relationship between negative air ions concentration and common mental disorders which helped to explore the influence of air ions concentration on common mental disorders. Methods Patients with schizophrenia, mental retardation and bipolar disorder who were hospitalized in The Third People's Hospital of Zhongshan from June 2010 to May 2017 were selected as subjects. All medical records of these subjects were collected and analyzed. Correlation analysis between the monthly admission of each disease and the average monthly air negative ion concentration was performed. Results Pearson correlation analysis showed that monthly admission of bipolar depression was positively correlated with negative air ions concentration ( r=0.34, P <0.01 ). The monthly concentration of negative air ions from January to December were 353, 336, 419, 564, 658, 729, 700, 665, 637, 512, 393, 479, and the cumulative admission of bipolar depression in the corresponding month were 37, 20, 36, 38, 55, 31, 29, 41, 44, 38, 26, 37. Conclusion The morbidity of bipolar depression increased at low level of negative air ions concentration but decreased at high level.
