目的 研究40岁及以上男性脑卒中的危险因素,探讨其风险等级与相关因素的路径关系,为此类人群的疾病预防提供科学的建议和措施.方法 采用随机抽样的方法,由培训合格的调查人员进行问卷调查,应用广义最小二乘-结构方程模型(GLS-SEM)进行统计分析.结果 共调查401人,年龄分布为(57.78±12.085)岁;结构方程模型的拟合效果较好,其中各路径系数均为正相关关系,生活方式对40岁及以上男性脑卒中风险等级的路径系数最大(1.631);相关疾病和既往病史对生活方式的路径系数为0.420和0.908,并且相关疾病和既往病史与40岁及以上男性脑卒中风险等级之间存在着中介作用,即前者通过影响生活方式来影响后者;明显超重或肥胖对生活方式的影响最小(0.030);脑卒中家族史对疾病史的影响最小(0.083).结论 所有危险因素中,高血压病史、血脂异常或未知、吸烟和既往脑卒中病史对40岁及以上男性脑卒中风险等级影响最大,此结果对社区40岁及以上男性居民脑卒中的防控,具有重要参考价值.

了解大学生校园贷的现状,采用分层抽样的方法,调查本校大学生742人,由培训合格的调查人员进行现场问卷调查和收集.探讨多种因素与使用校园贷的相关性,提高对“校园贷”的隐患和风险的认知度,为减少不良校园贷的使用人数提供科学依据.统计分析结果表明,使用校园贷的可能性是多个影响因素作用的结果,需积极采取有效地措施,引导大学生理性消费.

Objective: To examine the frequency and type of citations of articles published in Adverse Drug Reactions Journal and to reveal the characteristics of citations in this journal. Methods: The citations of articles published in Adverse Drug Reactions Journal from 2003 to 2007 were collected.

The citations in the top 20 cited journals in citation frequency were 22.8% of the total citations. Conclusion: The citation of articles published in Adverse Drug Reactions Journal has characteristics of a large number and a wide range. The journal is one of the important sources in drug safety information.
