Vitamin D deficiency and adverse fetal outcome

Background: Vitamin D deficiency is recognized as the most untreated nutritional deficiency in the world. It is plausible that vitamin D deficiency could make the fetal heart more vulnerable to distress/birth asphyxia. Vitamin D deficiency has been hypothesized to be associated with low birth weight, low Apgar score at birth, higher rates of still births and admission to NICU. The aim of present study was to study prevalence of vitamin D deficiency in pregnancy and evaluate perinatal outcome.Methods: The study was conducted in the department of obstetrics and gynecology, Kamla Nehru Hospital, Shimla, India over a period of 12 months. Six hundred women were included in the study.Results: All the mothers who had still births suffered from vitamin D deficiency and the severe vitamin D deficiency was there in 90.91% (30) of these subjects. Severe vitamin D deficiency was seen in 78.95% (75) of the subjects having babies with birth weights <2.5 kg compared to 61.16% (288) subjects of the other group.Conclusions: Adverse fetal outcome are more common in vitamin D deficient group.

Vitamin D deficiency and maternal complications

Background: Vitamin D deficiency is prevalent in India, a finding that is unexpected in a tropical country with abundant sunshine. Vitamin D deficiency is recognized as the most untreated nutritional deficiency currently in the world. Several studies reported the relationship between maternal vitamin D deficiency and adverse maternal and fetal outcomes including gestational diabetes, preeclampsia, preterm labour, low birth weight and increased rate of caesarean section.Methods: The study was conducted in the department of obstetrics and gynecology, Kamla Nehru Hospital, Shimla, Himachal Pradesh, India over a period of 12 months. Six hundred women were included in the study.Results: Forty-eight (8%) subjects developed preeclampsia-eclampsia syndrome, of which none had sufficient vitamin D levels, whereas 48 (100%) subjects had vitamin D deficiency.Conclusions: Maternal antenatal complications are more common in vitamin D deficient group.

Analysis of still births in a tertiary care system and changed scenario over six year period

Background: In India, the maternal and infant mortality rates have been steadily decreasing in recent years, but there has been no corresponding decrease in the perinatal mortality. Hence, there is need to evaluate the factors leading to this unfortunate event. The objective of this study was to find out various factors (especially preventable) responsible for perinatal stillbirths.Methods: An analytical comparative study in a tertiary care hospital comparing fresh and macerated still births over a period of one year in 2011 and 2017 and responsible factors were analysed.Results: Amazingly, despite improvement in the antenatal services, more institutional deliveries, there is no change in the incidence of still birth rate. However, there was decrease in the rate of still births due to extreme prematurity and congenital malformations. There was no change in incidence of PIH/ Eclampsia, IUGR and placental causes but there was substantial increase in the incidence of GDM.Conclusions: Perinatal mortality can definitely be reduced by strengthening and improving quality of antenatal services, early identification of high risk pregnancies, timely referral and appropriate intervention.

Prevalence of vitamin D deficiency in antenatal women

Background: Vitamin D has an increasingly recognised repertoire of non-classical actions, such as promoting insulin action and secretion, immune modulation and lung development. It therefore has the potential to influence many factors in the developing fetus. Several studies reported the relationship between maternal vitamin D deficiency and adverse maternal and fetal outcomes including gestational diabetes, preeclampsia, preterm labour, low birth weight and increased rate of caesarean section. The present study was undertaken to study the prevalence of vitamin D deficiency in antenatal women of Shimla, India.Methods: The study was conducted in the department of Obstetrics and Gynaecology, Kamla Nehru Hospital, Shimla, India over a period of 12 months. Six hundred women were included in the study.Results: Out of 600 subjects, 568 (94.67%) subjects had vitamin D deficiency and only 32 (5.33%) subjects had sufficient vitamin D levels. Vitamin D deficiency was more common in the vegetarians, dark skinned subjects and in those who were taking vitamin D supplements.Conclusions: It is concluded from this study that there is high prevalence of vitamin D deficiency in antenatal women of Shimla, India.
