Our aim is to explore general practitioners' (GPs') knowledge about EMF, and to assess whether different knowledge structures are related to the GPs' concern about EMF. Random samples were drawn from lists of GPs in Germany in 2008. Knowledge about EMF was assessed by seven items. A latent class analysis was conducted to identify latent structures in GPs' knowledge. Further, the GPs' concern about EMF health risk was measured using a score comprising six items. The association between GPs' concern about EMF and their knowledge was analysed using multiple linear regression. In total 435 (response rate 23.3%) GPs participated in the study. Four groups were identified by the latent class analysis: 43.1% of the GPs gave mainly correct answers; 23.7% of the GPs answered low frequency EMF questions correctly; 19.2% answered only the questions relating EMF with health risks, and 14.0% answered mostly "don't know". There was no association between GPs' latent knowledge classes or between the number of correct answers given by the GPs and their EMF concern, whereas the number of incorrect answers was associated with EMF concern. Greater EMF concern in subjects with more incorrect answers suggests paying particular attention to misconceptions regarding EMF in risk communication.
我们的目的是探究全科医生（GPs）关于电磁场（EMF）的知识，并评估不同的知识结构是否与全科医生对电磁场的担忧相关。2008年从德国全科医生名单中抽取随机样本。通过七个项目评估关于电磁场的知识。进行潜在类别分析以识别全科医生知识中的潜在结构。此外，使用包含六个项目的分数来衡量全科医生对电磁场健康风险的担忧。使用多元线性回归分析全科医生对电磁场的担忧与其知识之间的关联。共有435名全科医生（回复率23.3%）参与了该研究。潜在类别分析确定了四组：43.1%的全科医生给出的主要是正确答案；23.7%的全科医生正确回答了低频电磁场问题；19.2%的全科医生仅回答了与电磁场健康风险相关的问题，14.0%的全科医生大多回答“不知道”。全科医生的潜在知识类别之间，或全科医生给出的正确答案数量与其对电磁场的担忧之间没有关联，而错误答案的数量与对电磁场的担忧相关。错误答案较多的受试者对电磁场的担忧更大，这表明在风险沟通中应特别关注关于电磁场的误解。
