孕期及非孕期不同年龄组生育年龄女性骨密度比较分析

Comparison of bone mineral density in women of different age groups during pregnancy and non-pregnancy

目的研究不同年龄组孕期及非孕期生育年龄女性的骨密度情况,并进行对比分析和探讨。方法选取孕期女性1131例,非孕期生育年龄女性667例,按年龄分为<30岁组,30～39岁组和>39岁组。采用以色列定量超声骨强度仪测定其骨密度,按骨密度T值分为骨量正常组与骨量减少组(包括骨质疏松组)并记录一般情况。结果孕期与非孕期各年龄组组间内骨密度比较差异均存在统计学意义(P<0.05),生育期女性中小于30岁年龄组的骨量较其余两组明显减少,差异有统计学意义(P<0.05),而30～39岁组和大于39岁组骨量差异无统计学意义(P>0.05),孕期与非孕期骨密度比较差异无统计学意义(P>0.05)。结论孕期与非孕期生育年龄女性中低年龄段女性发生骨质减少更为明显,低年龄段生育期女性骨健康情况不容忽视,必须重视钙剂的及时补充和健康的生活方式。

Objective To compare, analyze, and explore the status of bone mineral density (BMD) of pregnant and non-pregnant women in different age groups. Methods A total of 1131 pregnant women and 667 non-pregnant women were divided into less than 30 years old group, 30-39 years old group, and over 39 years old group according to their ages. BMD was measured using Israeli quantitative ultrasound intensity meter. According to the T value of BMD, they were divided into normal bone mass group and osteopenia group (including osteoporosis group), and the general information was recorded. Results There were statistically significant differences of BMD among all ages in pregnancy and non-pregnancy groups (P<0.05). BMD decreased more significantly in women less than 30 years old than in the other two groups, and the difference was statistically significant (P<0.05). BMD was not different between 30-39 years old group and over 39 years old group (P>0.05). BMD between pregnant and non-pregnant women was not statistically significant (P>0.05). Conclusion Osteopenia is more obvious in pregnant and non-pregnant women at middle and young ages. The bone health condition of women at young age cannot be ignored. Calcium supplements and healthy lifestyle must be paid attention.
