Abstract

AIM

To assess associations of the serum level of 25-hydroxyvitamin D with insulin resistance and β-cell function in a healthy Chinese female population.

METHODS

This cross-sectional study included 1382 female participants free of type 2 diabetes who were recruited in Shanghai. Blood samples were collected within a winter season and the serum levels of 25-hydroxyvitamin D, fasting plasma glucose and insulin, and other biochemical parameters were determined. Insulin resistance and β-cell function were assessed using the homeostasis model assessments of insulin resistance (HOMA-IR) and β-cell function (HOMA-B), respectively.

RESULTS

Multiple linear regression analyses adjusted for age, parathyroid hormone, Ca(2+) and BMI revealed that independent inverse associations existed between the serum level of 25-hydroxyvitamin D and HOMA-IR (P<0.001) and between the serum level of 25-hydroxyvitamin D and HOMA-B (P=0.001).

CONCLUSION

Serum vitamin D level is significantly and independently associated with insulin resistance and β-cell function in a healthy Chinese female population.

摘要

目的

评估健康中国女性人群血清 25-羟维生素 D 水平与胰岛素抵抗和β细胞功能的相关性。

方法

本横断面研究纳入了 1382 名无 2 型糖尿病的女性参与者,她们均来自上海。在冬季采集血样,并测定血清 25-羟维生素 D、空腹血糖和胰岛素以及其他生化参数的水平。采用稳态模型评估胰岛素抵抗(HOMA-IR)和β细胞功能(HOMA-B)分别评估胰岛素抵抗和β细胞功能。

结果

经年龄、甲状旁腺激素、Ca(2+)和 BMI 校正的多元线性回归分析显示,血清 25-羟维生素 D 水平与 HOMA-IR(P<0.001)和 HOMA-B(P=0.001)之间存在独立的负相关关系。

结论

在健康的中国女性人群中,血清维生素 D 水平与胰岛素抵抗和β细胞功能显著且独立相关。
