Comparison of bone mineral density between early postpartum women and non-pregnant healthy women in Chongqing area / 重庆医学

ABSTRACT

Objective To investigate the change of bone mineral density(BMD) in the early postpartum period and non-pregnant healthy women with the same age.Methods The American GE company's dual energy X-ray BMD instrument(DXA) was used to conduct the BMD detection at lumbar spine and femoral neck of 1 055 cases of postpartum women and 889 non-pregnant women.The subjects were grouped according to different ages and body mass index(BMI).Then the BMD value in each group was calculated and the results were statistically analyzed.Results The lumbar spine and femoral neck BMD values in difference age groups of the postpartum women appeared decrease as compared with the non-pregnant women group,the difference was statistically significant in the lumbar spine(P＜0.05).Conclusion BMD of early postpartum women in Chongqing area is significantly decreased.
