广西壮族自治区农村居民精神分裂症患病率及影响因素分析

目的 了解广西壮族自治区农村地区≥15岁居民精神分裂症患病率的分布特征和影响因素,为保护当地居民身体健康提供科学依据.方法 2007年7-12月,采用多阶段分层整群抽样方法随机抽取10个县13910名≥15岁的农村居民为调查对象进行入户调查.以中国疾病预防控制中心提供的中文版本的复合性国际诊断问卷(CIDI3.0)为筛查工具,以国际疾病及相关健康问题分类第10版(ICD-10)为诊断标准.结果 广西农村≥15岁居民精神分裂症终生患病率为9.20‰.精神分裂症终生患病率在不同年龄之间差异有统计学意义(x2=21.653,P=0.001),25～岁组患病率(17.26‰)最高.不同教育水平人群的精神分裂症终生患病率差异有统计学意义(x2=5.008,P=0.025),高中及以上文化程度人群的患病率(4.74‰)低于初中及以下人群(10.12‰).不同婚姻状况的精神分裂症终生患病率差异有统计学意义(x2=58.770,P＜0.01),未婚人群患病率(22.56‰)最高.不同性别和不同民族间精神分裂症终生患病率差异均无统计学意义(P＞0.05).多因素非条件logistic回归分析显示,年龄、教育水平、婚姻状况3个因素进入回归模型,是影响广西农村地区精神分裂症患病的主要因素.结论 广西农村地区25～34岁、初中及以下文化程度者和未婚人群精神分裂症患病率较高,是广西农村精神分裂症防治的重点人群.
