To explore the relationship between posttraumatic stress disorder (PTSD) and preflood behavioral characteristics among children aged 7-15 years in Hunan, China.
In 2000, a retrospective study was carried out among children who had been exposed to the 1998 floods in Hunan. A multistage sampling method was used to select subjects from the flood-affected areas. A structured questionnaire administered to the children selected was used to diagnose PTSD based on the DSM-IV criteria. A parent questionnaire was used to measure preflood behavioral characteristics related to health, behavioral, and habit problems. The association between PTSD and preflood behavioral characteristics was assessed using χ(2)-tests and multivariate logistic regression.
A total of 7,038 children from 13,450 households, aged 7-15 years, were investigated. The overall prevalence of PTSD was 2.05%. Generally, the PTSD-positive rate increased with increasing scores for behavioral characteristics.
Preflood behavioral characteristics are an important factor influencing the prevalence of PTSD among children exposed to floods. It is therefore necessary to give special attention to children with behavioral problems in order to reduce the psychological impact of floods.
探讨中国湖南 7-15 岁儿童创伤后应激障碍（PTSD）与洪灾前行为特征之间的关系。
2000 年，对湖南遭受 1998 年洪灾的儿童进行了一项回顾性研究。采用多阶段抽样方法，从受灾地区选取研究对象。对选取的儿童进行了结构问卷调查，以 DSM-IV 标准诊断 PTSD。使用家长问卷测量与健康、行为和习惯问题相关的洪灾前行为特征。采用卡方检验和多因素逻辑回归评估 PTSD 与洪灾前行为特征之间的关系。
共调查了 13450 户家庭的 7038 名 7-15 岁儿童。PTSD 的总患病率为 2.05%。一般来说，PTSD 阳性率随行为特征得分的增加而增加。
洪灾前行为特征是影响儿童暴露于洪灾后 PTSD 患病率的一个重要因素。因此，有必要特别关注有行为问题的儿童，以减少洪灾的心理影响。
