   摘要
   目的：关注维生素D，补充维生素D能带来很多潜在获益。但是关于维生素D的知识、信念和态度而实施公共卫生措施和专业指导的信息很少。
   设计：定性焦点组研究
   参与者：58例疾病状态、性别、年龄和种族不同的成人患者
   设置：在伦敦东部进行的一项大型公众调查
   结果：许多调查者对维生素D缺乏认知，包括饮食来源和政府建议。大多数调查者知道要晒太阳，但是困惑于日光暴露存在风险与获益。维生素D的医学观点很突出，尤其是来源于支持维生素D补充的医师，他们谈及维生素D的剂量、不良反应和常规检测。含维生素D的食物配方存在争议，反对功利主义（更好地服务于大多数）和自由主义（自由选择）。
   结论：关于维生素D的知识有限。需要有关日光暴露的风险与获益的更清晰的信息。健康专业人士进行的维生素D检测与补充，有助于维生素D观点的医疗化，且能给一些高危患者带来潜在获益。卫生政策应该解决公众对于维生素D来源和效果的清晰信息（包括日光暴露的风险与获益）需求和考虑到关于配方的不同观点。需要有关检测和补充的专业指导来纠正不恰当的医疗化。

Abstract
OBJECTIVE:Lay interest in vitamin D and the potential benefits of supplementation is considerable, but little information exists concerning lay knowledge, beliefs and attitudes towards vitamin D to inform public health initiatives and professional guidance.
DESIGN:Qualitative focus group study.
PARTICIPANTS:58 adults capturing diversity in disease status, gender, age and ethnicity.
SETTING:A large general practice in east London.
RESULTS:Many respondents lacked knowledge about vitamin D, including dietary sources and government recommendations. Most were positive about sun exposure, but confused by ambiguous health messages about risks and benefits of sunshine. Medicalised views of vitamin D were prominent, notably from those in favour of supplementation, who talked of "doses", "side effects" and "regular testing." Fortification of food with vitamin D was controversial, with opposing utilitarian (better overall for the majority) and libertarian (freedom to choose) views.
CONCLUSIONS:Knowledge about vitamin D was limited. Clearer messages are needed about risks and benefits of sun exposure. Testing and supplementation by health professionals, while potentially useful in some high-risk groups, have contributed to a medicalised view of vitamin D. Health policy should address the public's need for clear information on sources and effects of vitamin D, including risks and benefits of sun exposure, and take account of divergent views on fortification. Professional guidance is needed on testing and supplementation to counter inappropriate medicalisation.
