The incidence of preterm birth is increasing in many countries, meanwhile, the survival rate of preterm babies has dramatically improved in developed countries [33, 34]. Preterm birth represents a significant cause of death and can lead to serious harm to survivors all around the world . In our study, maternal vitamin D status had no correlation with preterm birth. Nonetheless, a possible negative correlation between maternal vitamin D status and preterm birth was reported [36, 37]. A recent meta-analysis consisted of 24 observational studies revealed the association between low vitamin D levels (< nmol/L) and increased risk of preterm birth (OR = 1.58, 95%CI (1.08 to 2.31) [38,39,40,41] while studies from New Zealand and China shared the similar view with us. The discrepancy ple size, research methods confounding factors, various 25(OH)D cutoff values, population characteristics and methods for measuring vitamin D status. Since we haven't excluded some cases with risk factors related to PTB, the certain relation might be concealed. In addition, molecular research demonstrated that vitamin D metabolism can be affected by single nucleotide polymorphisms (SNP) of VDR genes such as BsmI, FokI, TaqI, and ApaI, resulting in different maternal serum vitamin D concentrations and functions in downstream, even given the same amount of supplement .
