People have been exposed to a lot of information regarding vitamin D, with evidence suggesting that vitamin D may be involved in numerous health conditions, subsequently creating concerns about vitamin D insufficiency. As a result, what do people really know or believe about this topic? In this cross-sectional study, we assessed vitamin D-related knowledge and beliefs in 59,273 French adults (NutriNet-Santé cohort) using a specific questionnaire. Answers to this questionnaire were weighted according to the French sociodemographic distribution and compared across individual characteristics, using χ²-tests. Physicians and media were identified as key information providers. Participants did not always accurately cite vitamin D sources (e.g., 72% only for sun exposure, fatty fish: 61%) or established health effects (e.g., bone health: 62%-78%). Conversely, they mentioned incorrect sources and health effects for which there is no consensus yet (e.g., skin cancer). These findings were modulated by age/generational and socioeconomic factors. A strong inconsistency was also observed between participants' true vitamin D status (plasma 25-hydroxyvitamin D concentration) and their opinion about it. This study, the first in Europe with such a large sample, stresses the need for simple and up-to-date supports of communication for the public and healthcare professionals regarding sources and health effects of vitamin D.
人们已经接触到了大量关于维生素D的信息，有证据表明维生素D可能与多种健康状况有关，这进而引发了人们对维生素D缺乏的担忧。那么，人们对这个话题究竟了解多少或相信些什么呢？在这项横断面研究中，我们使用一份特定问卷，对59273名法国成年人（NutriNet-Santé队列）的维生素D相关知识和信念进行了评估。根据法国社会人口分布情况对该问卷的答案进行加权，并使用χ²检验，对个体特征进行比较。医生和媒体被确定为关键信息提供者。参与者并不总是能准确说出维生素D的来源（例如，仅提及阳光照射的占72%，富含脂肪的鱼类占61%）或已确定的健康影响（例如，骨骼健康占62%-78%）。相反，他们提到了一些尚未达成共识的错误来源和健康影响（例如，皮肤癌）。这些发现受到年龄/代际和社会经济因素的影响。在参与者的实际维生素D状态（血浆25-羟基维生素D浓度）与其对此的看法之间，也观察到了强烈的不一致。这项欧洲首例如此大规模样本的研究强调，需要为公众和医疗保健专业人员提供关于维生素D来源和健康影响的简单且最新的沟通支持。
