[摘要] 目的：探讨内蒙古高氟地区血清维生素D含量和2型糖尿病的关系，为临床合理防治2型糖尿病提供依据。方法：本研究均选择本地居住10年以上居民，其中2型糖尿病75例，对患者的血清25羟基维生素D[25(OH)D3]含量、血清钙磷、血糖(BG)、糖化血红蛋白(HbA1c)、胰岛素、C肽、血脂谱、体重指数(BMI)、胰岛素抵抗指数和β细胞功能指数(HOMAβc)等指标进行综合分析，同时选取51例健康人的血清25(OH)D3含量作为对照。结果：2型糖尿病组与健康对照组的25(OH)D3水平比较，差异有高度统计学意义(P<0.01)，分别为(2.87±2.83)、(14.38±14.01)nmol/L，两者均明显低于其他地区和国家最低标准(50 nmol/L)；血清25(OH)D3水平和HbA1c、BMI和空腹血糖(FBG)呈负相关(r=-0.240、-0.231、-0.392，均P<0.05)；血清25(OH)D3水平和HOMAβc呈正相关(r=0.274，P<0.05)。结论：内蒙古高氟地区维生素D水平较其他地区和国家明显降低；维生素D水平和2型糖尿病的发病和病情严重程度有关。给予本地区居民补充维生素D，一方面可以减少高氟损害，另一方面可以延缓2型糖尿病的病情。

[Abstract] Objective: To determine the relationship between vitamin D levels and type 2 diabetes mellitus in the endemic fluorosis area of Inner Mongolia Autonomous Region, and to provide evidence of reasonable prevention and treatment method to type 2 diabetes patients in clinic. Methods: All of the groups had lived in the local region above ten years. Serum 25-hydroxyvitamin D, calcium and phosphorus, fasting blood glucose, HbA1c, body mass index (BMI), serum lipid profile, fasting blood insulin, insulin resistant index (HOMAIR) and β-cell function (HOMAβ-cell) were analyzed in 75 patients with type 2 diabetes, and serum 25-hydroxyvitamin D was detected in 51 healthy adults who were assessed as control group. Results: Mean(SD) 25-hydroxyvitamin D levels of type 2 diabetes group and health control group were (2 ......
