Purpose : This study was conducted to investigate the effect of pregnancy and parity on bone marrow density using Dual Energy X-ray Absorptiometry (DXA) after parturition
Methods : The observation cases who was over 20 and under 35 years old just after childbirth were admitted twice to woosuk university hospital from Aug 2000 to July 2005. During the first admission period, we measured the bone marrow density(BMD) using DXA in 13th day, and when the patient came to the hospital just after childbirth again, we followed up the BMD in 13th day. The evaluation index of this report was comparison of the T-score which was about the lumbar spine(L1-L4) BMD and femur neck BMD.
Results : The continuous parturition was increased the lumbar spine BMD(P<<0.05), and decreased the femur neck BMD but it had no meaning. In the cases of the parturition interval under 24 months regarded as siblings born within a year of each other, the analysis results of BMD showed increase in lumbar spine BMD. In the cases of the parturition interval over 24 months, there was increased in lumbar BMD, and decreased in femur neck BMD. To the analysis of the weight variation, the increased BMI group has a significant increase in lumbar spine BMD, and the decreased BMI group also increase in lumbar spine BMD but there was no meaning about that.
Conclusion : The continuous parturition was increased the lumbar spine BMD.
