目的了解蚌埠市中学生儿童期虐待与躯体亚健康的关系以及孤独感在其中的中介和调节作用,为改善青少年身心健康状况提供依据。方法采用分层整群随机抽样方法,从蚌埠市抽取5 116名中学生,使用青少年亚健康多维评定问卷、儿童期虐待问卷、孤独感自评量表对研究对象进行问卷调查。结果中学生躯体亚健康状态的报告率为26.2%。中学生躯体亚健康与孤独感和儿童期虐待得分均呈负相关（r值分别为-0.136,-0.127,P值均〈0.01）,儿童期虐待和孤独感得分呈正相关（r=0.079,P〈0.01）。Logistic回归分析结果显示,女生、高孤独感、高儿童期虐待及高中生均为中学生躯体亚健康的危险因素（P值均〈0.01）。孤独感在儿童期虐待和身体亚健康之间具有部分中介效应,中介效应占总效应的比例为30.27%。孤独感在儿童期虐待和身体亚健康之间具有调节效应,随着孤独感程度的加重,儿童期虐待对身体亚健康的负向预测作用增强。结论孤独感在中学生儿童期虐待对躯体亚健康的影响中具有中介和调节作用。

Results Totally 26.2% of the adolescents were reported in status of physical sub-health.The reporting rate of status of physical sub-health differed among different gender and study stages（P〈0.05）.Childhood abuse was positively correlated with loneliness（P〈0.01）.Logistic regression analysis showed that girls,high loneliness,high childhood abuse and senior high school students were risk factors to physical subhealth（P〈0.01）.The partial mediating effect of loneliness on the relations between childhood abuse and physical subhealth was significant（30.27%）.The moderating effect of loneliness on the relations between childhood abuse and physical sub-health was significant,with the severity of loneliness,childhood abuse was negative reinforcement to predict the physical sub-health.
