Drug Information available for: Vitamin D




Primary Outcome Measures :
  1. Prevalence of vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Number of patients with vitamin D deficiency after testing of vitamin D blood level at admission for prenatal care in our clinic


Secondary Outcome Measures :
  1. BMI as a risk factor for vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the patient's BMI and their vitamin D blood level?

  2. Ethnicity as a risk factor for vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the patient's ethnicity and their vitamin D blood level?

  3. Age as risk factor for vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the patient's age and their vitamin D blood level ?

  4. Period of the year as risk factor for vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the period of the year at the time of the blood testing and the vitamin D blood level?

  5. Smoking Status as risk factor for vitamin D deficiency [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the patient's smoking status and the vitamin D blood level ?

  6. Association between vitamin D blood level and gestational diabetes mellitus [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the vitamin D blood level and the occurrence of gestational diabetes mellitus?

  7. Association between vitamin D blood level and gestational hypertension and preeclampsia [ Time Frame: Between the 1th and the 36th week of pregnancy ]
    Presence of an association between the vitamin D blood level and the occurrence of gestational hypertension and preeclampsia ?


Other Outcome Measures:
  1. Association between vitamin D blood level and the mode of delivery at birth [ Time Frame: At delivery time ]
    Presence of an association between the vitamin D blood level and the mode of delivery (Vaginal delivery, instrumentalized delivery, primary and secondary cesarean)?

  2. Association between vitamin D blood level and the gestational age at delivery [ Time Frame: At delivery time ]
    Presence of an association between the vitamin D blood level and the gestational age at delivery? Occurrence of preterm birth (before 37W) or postterm birth (after 40W)?

  3. Association between vitamin D blood level and newborn growth [ Time Frame: From week 1 until birth ]
    Presence of an association between vitamin D blood level and the occurrence of intrauterin growth retardation or small-for-gestational age child? With assessment of measure like length, weight, head perimeter.
