Abstract:
Objective To investigate the effects of 25‐hydroxy vitamin D [25(OH)D] status on the pregnancy outcome in the second and third trimester pregnant women living .Methods A total of 143 pregnant women (12 -42 weeks gestational age) were participated in the study .Their serum 25(OH)D concentrations were detected by liquid chromatography‐mass spectrometry method .Finally ,vitamin D status was assessed according to sufficiency group(n= 32) ,inadequacy group(n= 49) ,insufficiency group(n=51) and deficiency group(n=11) .Retrospective analysis were adopted to follow up the pregnancy outcome of pregnant women .Results (1)The average serum 25(OH)D level was(22 .49 ± 9 .51)ng/mL in the second and third trimester of pregnancy . (2)Abortion rate were 3 .1% (1/32) in sufficient group ,2 .0% (1/49)in inadequacy group ,11 .8% (6/51) in insufficiency group , 36 .4% (4/11) in deficiency group ,fetal distress incidence were 3 .1% (1/32) ,8 .2% (4/49) ,11 .8% (6/51) ,36 .4% (4/11) in each group .Abortion ,fetal distress rate were higher in deficiency group compared with the other three groups(P<0 .05) .(3)Bacterial vaginosis incidence were 0(0/32) ,4 .1% (2/49) ,13 .7% (7/51) ,27 .3% (3/11)in each group ,deficiency group and insufficiency group were higher(P<0 .05) .(4)Otherwise ,the gestation period were (39 .48 ± 1 .44) weeks in sufficient group ,(39 .00 ± 1 .70) weeks in inadequacy group ,(38 .09 ± 2 .01) weeks in insufficiency group ,(37 .29 ± 0 .49) weeks in deficiency group ,pregnancy cycle was significantly shorter when 25(OH)D<20 .00 ng/mL (P<0 .05) .Conclusion Vitamin D deficiency in pregnant women could increase the risk of abortion ,fetal distress ,bacterial vaginosis ,and significantly shorten the gestation period .
