)[摘 要]目的 探讨妊娠期妇女骨代谢指标和骨密度(BMD)的变化及其相关性。方法 选取2014年4月至2018年2月在
浙江医院产科门诊建卡并进行常规产前检查的妊娠妇女300例进行前瞻性研究,其中妊娠早期组(~13+6
孕周)100例、妊娠中期组(14~27+6孕周)100例、妊娠晚期组(≥2
8孕周)100例,另选取同期健康未孕妇女100例为对照组。检测四组的血清25-羟维生素D、骨钙素N端片段(N-MID)、Ⅰ型胶原氨基端延长肽(TP1NP)、碱性磷酸酶(ALP)、BMD、骨钙素(BGP)、血清钙、血清磷,并对其进行统计分析。结果 妊娠早期组、中期组和晚期组的25-羟维生素D水平均低于对照组(t值分别为-13.785、-13.196、-13.351,均P<0.05);早期组、中期组的N-MID、TP1NP、ALP水平均低于晚期组(t值分别为-21.588、-20.802、-25.535、-17.658、-19.925、-1
7.824,均P<0.05);晚期组的TP1NP、ALP水平均高于对照组(t值分别为16.349、25.141,
均P<0.05)。早期组、中期组和对照组的BMD、血清钙水平均高于晚期组(t值分别为2.325、2.804、3.180、2.561、-5.121、-2.706,均P<0.05),早期组、中期组和对照组的BGP水平均低于晚期组(t值分别为-9.457、-10.272、9.822,均P<0.05)
。妊娠期,血清25-羟维生素D与BMD呈正相关关系(r=0.411,P<0.01);TP1NP、ALP、BGP与BMD均呈负相关关系(r值分别为-0.392、-0.481、-0.328,均P<0.05)。结论 妊娠期妇女骨代谢活跃加强,25-羟维生素D缺乏可能会增加妊娠妇女发生骨
密度降低的风险。

ective To explore the changes of bone metabolism index and bone mineral density(BMD)in pregnant women andtheir correlation.Methods A prospective study was conducted in 300pregnant women in Zhejiang 
Hospital from April 2014toFebruary 2018,including 100cases in early pregnancy 
group(<13+6

pregnantwomen were selected in control group
.Serum 25-hydroxyvitamin D,osteocalcin N terminal fragment(N-MID),type I collagen N-terminal extension peptide(TP1NP),alkaline phosp荫蔽
hatase(ALP),BMD,osteocalcin(BGP),serum calcium,and serumphosphorus were detected in four 
groups.Results The levels of 25-hydroxyvitamin D in pregnant group 
were lower than those in thecontrol group(t value was-13.785,-13.196and-13.351,respectively,a
ll P<0.05).The N-MID,TP1NP and ALP levels inearly pregnancy group and second trimester group were lower than those in late pregnancy 
group(t value was-21.588,-208.82,-25.535,-17.658,-19.925,and-17.824,respectively,all P<0.05).The TP1NP and ALP levels in late pregnancy 
groupwere higher than those in the control group(t value was 16.349and 25.141,respectively,both P<0.05).The BMD and serumcalcium lev
els in early pregnancy group,second trimester group and the control group were higher than 
those in late pregnancygroup(t value was 2.325,2.804,3.180,2.561,-5.112and-2.706,respectively
,all P<0.05).The BGP levels in earlypregnancy group,second trimester group and the control group were lower than those in late pregnancy 
group(t value was-9.557,-10.272and 9.822,respectively,all P<0.05).During pregnancy,serum 25-hydroxyvitamin D was positively 
correlatedwith BMD(r=0.411,P<0.01).TP1NP,ALP and BGP were negatively 
correlated with BMD(r value was-0.392,-0.481and-0.328,respectively,all P<0.05).Conclusion Osteogenic metabolism is strongly
