Relationship between absorption of dietary calcium and Bsm I polymorphism of VDR gene in childbearing women

  Objective   To examine the relationship between the absorption of dietary calcium and Vitamin D₃ receptor (VDR)gene Bsm I RFLPs in childbearing women.

  Methods   Forty subjects were selected from three hundred young famale students aged 18~23 in 2001.After identifying the VDR gene FokI RFLPs, the women were given the representative diets during the 3-day adaptation period and the 12-day metaboism period.The copy food and drinking for measurement of untrients and also the complete feces each day were collected.

  Results   As expected, the significant difference of the absorption of diet calcium between VDRBsm Igene RFLPs(bb < Bb)in chidbearing women was observed(P < 0.05).

  Conclusion   More attention should be paid to the low calcium absorption of chidbearing women with Bb in our country.
