This study aimed to assess the attitudes, practices and knowledge of general practitioners (GPs) with regards to vitamin D. A cross-sectional survey of a random sample of GPs stratified by location of practice (rural/remote or metropolitan) and employment status (full-time or part-time) in New South Wales (NSW), Australia was conducted. Of 500 respondents, 58.1% (95% CI 53.8-62.4) reported that up to 39% of their tested patients showed vitamin D deficiency or insufficiency and a further 37.7% (95% CI 33.5-41.9) of respondents said that over 40% of their patients were vitamin D insufficient. Vitamin D supplementation and advice to receive more natural sunlight were the most common ways vitamin D insufficiency was managed (97.1%; 95% CI 95.6-98.6 and 82%, 95% CI 78.6-85.4, respectively). Some gaps in knowledge were identified. Most respondents (64%; 95% CI 59.8-68.2) believed that a person of average sun sensitivity required 10 min of direct sun exposure during summer in peak UV time and a further 21.6% (95% CI 18.0-25.2) believed that people required 30 min of direct sun. A third of respondents (33.1%; 95% CI 29.0-37.2) advised their patients to use sun protection at all times during winter. In general, the attitude items showed that respondents expressed greater concern about vitamin D deficiency than skin cancer. The results reveal some confusion in general practice regarding vitamin D, sun exposure, sun protection and skin cancer risk. Some of the advice that GPs are offering may needlessly increase their patients' risk for vitamin D insufficiency or skin cancer.
本研究旨在评估全科医生（GP）对维生素 D 的态度、实践和知识。在澳大利亚新南威尔士州（NSW），对按执业地点（农村/偏远地区或大都市）和雇佣状况（全职或兼职）分层的 GP 进行了一项随机抽样的横断面调查。在 500 名受访者中，58.1%（95%CI 53.8-62.4）报告说，多达 39%的被测患者存在维生素 D 缺乏或不足，另有 37.7%（95%CI 33.5-41.9）的受访者表示，超过 40%的患者存在维生素 D 不足。维生素 D 补充剂和建议多接受自然阳光是管理维生素 D 不足最常见的方法（97.1%；95%CI 95.6-98.6 和 82%，95%CI 78.6-85.4）。知识上存在一些差距。大多数受访者（64%；95%CI 59.8-68.2）认为，平均日晒敏感的人在夏季紫外线高峰时段需要 10 分钟的直接日晒，另有 21.6%（95%CI 18.0-25.2）认为人们需要 30 分钟的直接日晒。三分之一的受访者（33.1%；95%CI 29.0-37.2）建议患者在冬季任何时候都使用防晒措施。总的来说，态度项目表明，受访者对维生素 D 缺乏的关注程度大于对皮肤癌的关注。结果表明，普通实践中存在一些关于维生素 D、日晒、防晒和皮肤癌风险的混淆。GP 提供的一些建议可能会不必要地增加患者维生素 D 不足或皮肤癌的风险。
