童年环境与成年后红细胞相关参数的关系:生命史策略与黑暗三联征的链式中介作用

Relationship between childhood environment and red blood cell parameters in adulthood:the chain mediating role of life history strategy and dark triad

目的:立足于生命史理论,揭示童年环境对成年后红细胞相关参数的影响。方法:采用童年环境量表、生命史策略量表、黑暗三联征量表对234名体检人员[男118人,女116人;年龄18~55(24.2±5.1)岁]进行问卷调查,并收集血常规检查中红细胞相关参数(红细胞计数、血红蛋白、平均红细胞体积、平均红细胞血红蛋白含量/浓度)。使用Amos 24.0,以童年环境严酷性/童年环境不可预测性为自变量,以生命史策略,黑暗三联征3个维度(马基雅维利主义、精神病态和自恋)为中介变量,以各红细胞参数为因变量,分别建立链式中介模型并加以检验。结果:链式中介模型显示,童年环境越严酷,自恋水平越高,平均红细胞体积和平均红细胞血红蛋白含量越低,自恋在其中起完全中介作用;童年环境越不可预测,自恋水平也越高,平均红细胞体积越低,自恋在其中起完全中介作用(P<0.05)。结论:童年环境的严酷和不稳定可对成年个体红细胞和血红蛋白产生直接影响,还可能通过黑暗人格的发展(主要是自恋)激发红细胞产生变化。

Aim:To reveal the influence of childhood environment on red blood cell parameters in adulthood based on the life history theory.Methods:A total of 234 individuals[118 males and 116 females,with age from 18 to 55(24.2±5.1)years]accepting physical examination were surveyed using Enviroment Conditional Scale,Mini-K,Dirty Dozen scales,and the data of red blood cell parameters in routine blood test were collected.The chain mediating models were constructed with harshness/unpredictability of childhood environment as independent variable,red blood cell parameters as dependent variables,and life history strategy and the 3 dimensions of dark triad as mediating variables using Amos 24.0.Results:The chain mediating models showed that the more harsh the childhood environment was,the high was the level of narcissism,the lower were mean red blood cell volume and mean concentration of hemoglobin in red blood cells,and narcissism played a mediating effect in it;the more unpredictable the childhood environment was,the high was the level of narcissism,the lower was mean red blood cell volume,and narcissism played a mediating effect in it(P<0.05).Conclusion:Harshness and unpredictability of childhood environment have impact on red blood cells and hemoglobin in adulthood,and can also trigger changes in red blood cells through the development of dark personality(mainly narcissism).
