Context: As bone metabolic markers, recent studies indicated vitamin D and osteocalcin (OC) were also involved in energy metabolism. While the exact relationship between vitamin D and OC in regulating energy metabolism is unclear. One of the possibilities is that: low vitamin D could lead to secondary hyperparathyroidism and following high bone turnover, which would enhance the quantity of bioactive OC.

Objective: Our aim was to study whether OC mediated the metabolic effect of vitamin D, along with their interaction on glycolipid metabolism in a cross-sectional study.

Method: A total of 701 Chinese type 2 diabetic patients, aged from 27 to 93, were recruited. Spearman correlation and linear regression analysis were performed. OC and OC * 25(OH)D were added to the regressions in order to study the interaction effect.

Results: The inverse associations of 25(OH)D with HbA1c(beta=−0.013, P=0.001), FPG (beta=−0.019, P=0.001), 2hPG (beta=−0.020, P=0.018), TG (beta=−0.005, P=0.021) and positive associations with 2hCP (beta=−0.014, P=0.004), HDL (beta=0.002, P<0.001) and HOMA2-%B (beta=0.250, P=0.003) were independent of PTH and OC in type 2 diabetics. The significant interaction of 25(OH)D and OC on HOMA2-%B (P for interaction=0.0362) were observed in this study.

Conclusion: No evidence suggests that OC mediates the vitamin D metabolic effect in our study. 25(OH)D combining with OC may have greater facilitation to beta-cell function.
