Abstract

OBJECTIVES
This study was conducted to examine the association of serum Vitamin D with insulin resistance and β-cell function in Korean health checkup examinees.
METHODS
This study subjects were 374 healthy adults (199 males, 175 females) over the age of 20, who visited a general hospital medical center located in Haenam-gun, Jeollanam-do. To find the association of Vitamin D with HOMA-IR and HOMA-β, the used statistical analysis were ANOVA and ANCOVA.
RESULTS
Of the study subjects, the level of serum Vitamin D defined by deficient group, insufficient group and sufficient group was 38.5%, 48.1% and 13.4%, respectively. According to the level of serum Vitamin D, the mean values of HOMA-IR were 1.92±1.08 in sufficient group, 1.99±1.04 in the insufficient group and 2.91±1.05 in deficient group and there were statistically significant different(p<0.001). The mean values of HOMA-β were 84.69±1.07 in sufficient group, 78.41±1.04 in the insufficient group and 80.48±1.04 in deficient group, and there were not significant. As a result of ANCOVA, adjusted mean of HOMA-IR were statistically significant different (p<0.001), but those of HOMA-β were not statistically significant according to the level of serum Vitamin D.
CONCLUSIONS
The insufficient level of serum Vitamin D was relatively high in healthy adults who live in rural area, and it was found that HOMA-IR significantly increased when Vitamin D was deficient. To prevent insulin resistance or diabetes, it is necessary to provide sufficient information related to sufficient production of Vitamin D such as Vitamin D supplement, sun exposure, food intake and etc.
