Data from article: Determinants of Vitamin D supplementation among individuals with type 1 diabetes. Table S6 A survey in T1DM population using a simple, anonymous, author’s questionnaire was performed. The questions involved data on basic characteristics of the respondent, diabetic history, presence of chronic complications, comorbidities, VD supplementation status, influence of the social environment (family doctor, medical specialist, relative friend recommendation; relative or friends supplements VD), knowledge on VD from Internet/media/books (self-education), and personal motivation on VD supplementation. The term „medical specialist” refers to the physician with 4.5-6.5 postgraduate specialization training. The survey was performed in Poland, in the local language. The inclusion criteria involved: individuals with type 1 diabetes aged at least 16 years. Incomplete surveys and responses from people with other types of diabetes were excluded from the analysis. To the study, patients in the Department of Diabetology and the outpatient clinic were requested to fulfilling a paper version of the questionnaire. The data from paper surveys were prescribed to the RedCap database. Furthermore, we prepared a digital version of the survey in RedCap that was prepared and the links to the survey on Facebook groups dedicated to Polish diabetics were spread. The data was collected from October 2018 through April 2019. Body mass index (BMI) was counted based on the declared weight and height. Overweight was defined as BMI ≥ 25 kg/m2 and below 30 kg/m2, and obesity as BMI ≥ 30 kg/m2. Table S7 Additionally, a short, anonymous author questionnaire dedicated to diabetologists or residents of diabetology was prepared. The survey contained the questions on personal VD supplementation status, motivation and whether the respondent recommends patients VD supplementation. A link to the digital survey was sent via e-mail to diabetologists associated with the local branch of Diabetes Poland.本文数据集来源： 1型糖尿病患者维生素D补充的影响因素 补充表S6 本研究采用简易匿名自制问卷，针对1型糖尿病（T1DM）人群开展调查。问卷内容涵盖受访者基本特征、糖尿病病史、慢性并发症与合并症患病情况、维生素D（VD）补充现状、社会环境影响因素（家庭医生、医学专科医师、亲友推荐；亲友补充维生素D情况）、通过互联网/媒体/书籍获取的维生素D知识（自主学习），以及个人进行维生素D补充的动机。本研究中“医学专科医师”指接受过4.5至6.5年研究生专科培训的医师。本次调查在波兰开展，采用当地语言进行。纳入标准为：年龄≥16岁的1型糖尿病患者。本研究排除填写不完整的问卷，以及其他类型糖尿病患者的应答数据。 本研究邀请糖尿病科病房及门诊患者填写纸质版问卷，纸质问卷数据录入电子数据采集系统（RedCap）。此外，我们在RedCap平台上搭建了电子版问卷，并将问卷链接发布至针对波兰糖尿病患者的Facebook群组中。数据收集时间为2018年10月至2019年4月。体质指数（BMI）根据受访者自述的身高与体重计算得出。超重定义为BMI≥25 kg/m²且<30 kg/m²，肥胖定义为BMI≥30 kg/m²。 补充表S7 此外，本研究还设计了一份简易匿名自制问卷，针对糖尿病专科医师或糖尿病专科住院医师开展调查。问卷内容涵盖个人维生素D（VD）补充现状、补充动机，以及是否会向患者推荐维生素D补充。研究通过电子邮件向隶属于波兰糖尿病学会地方分会的糖尿病专科医师发送了电子版问卷链接。
