目的了解广州市城区糖尿病患者对糖尿病知识认知与需求情况。方法选择广州市城区居民2型糖尿病现况调查中既往已诊断和新诊断的2型糖尿病患者作为调查对象,采用结构式问卷,询问是否患有糖尿病,以及性别、年龄、民族、职业、文化程度、婚姻状况、家庭收入等社会人口学特征和糖尿病相关知识和需求。结果既往已诊断糖尿病患者的各项糖尿病知识得分均显著高于新诊断糖尿病患者,两组调查对象均为糖尿病治疗和并发症知识得分高于糖尿病基础知识、临床症状知识和病因知识得分。既往已诊断和新诊断糖尿病患者对糖尿病知识的需求存在差异,前者希望了解糖尿病治疗知识,后者想了解糖尿病预防知识,二者均最希望“由医务人员举办讲座”来获得糖尿病知识。结论已诊断和新诊断糖尿病患者对糖尿病知识的了解和需求存在差异,对两组患者开展健康教育的内容应有所分别。 Objective To understand the knowledge and needs of diabetics in urban areas of Guangzhou.
