Pregnant women are a risk group vitamin D insufficiency found among greater than 50% of pregnant females. Actually, there few researches and knowledge which associate the Maternal 25(OH) D level and premature labour, and no one carried in Iraq. The aim of this research is to find out any relation between the maternal plasma 25(OH) D levels of females who have gave birth to premature (< 36 weeks) in comparison to females with full-term neonates in both groups.  The current study is a case control research was carried out between January-August 2020, at the department of gynecology and obstetrics at Azadi Teaching Hospital in Kirkuk Governorate. A convenient sample was randomly selected consist of 30 Mothers with premature delivery, compared with 30 mothers term pregnancy delivery, the newborns were weighing >2500g and appropriate for gestational age. Revision of maternal ANC cards were carried out for investigations, ultrasonography, date of LMP of mothers’, as well as fetal anthropocentric measurements through the conception period. The mean Vitamin D level was (18.6±6.7) among preterm deliveries, which is lower significantly from those with full term delivery (27.5±6.2), P value < 0.0001, as represented in figure 1. Deficient vitamin D level was reported among 15(50%) of preterm delivered mothers versus 6(20%) of full term mothers. insufficient vitamin D level was reported among 12(40%) of preterm delivered mothers versus 9(30%) of full term mothers. sufficient vitamin D level was reported among 3(10%) of preterm delivered mothers versus 15(50%) of full term mothers. The low levels Vitamin D level is significantly associated with premature deliveries.
