BackgroundAsian Indian women are predisposed to develop obesity, metabolic syndrome and vitamin D deficiency. Relationship of vitamin D deficiency with blood glucose levels has not been explored in Asian Indian women with pre-diabetes.ObjectiveWe evaluated the associations of serum 25-hydroxy vitamin D (25(OH)D) concentrations among adult women with the pre-diabetes residing in North India (Delhi).MethodsThis cross-sectional population-based study involved 797 women with pre-diabetes aged 20–60 years. Blood pressure, body mass index (BMI), fasting blood glucose (FBG), extent of sun exposure and serum 25(OH)D levels were assessed. For purpose of analysis, serum 25(OH)D levels (nmol/L) were categorized in quintiles as follows: 0–21.5 (first quintile), 21.51–35.60 (second quintile), 35.61–46.50 (third quintile), 46.51–62.30 (fourth quintile) and >62.31 (fifth quintile).ResultThe prevalence (%) of vitamin D deficiency, insufficiency and sufficiency was 68.6, 25.9 and 5.5, respectively. Mean age (p=0.004), systolic (p=0.05) and diastolic (p=0.04) blood pressure, weight (p=0.03), BMI (p=0.04) and FBG (p=0.02) were significantly higher in subjects with vitamin D deficiency as compared with those with vitamin D insufficiency and sufficiency. Unadjusted mean values of FBG were significantly decreased in fourth (p=0.02) and fifth quintiles (p=0.030) of 25(OH)D levels as compared with second quintile. Furthermore, after adjusting for age and family income FBG levels were significantly increased in first quintile (compared with fourth (p=0.012) and fifth (p=0.018) quintiles) and second quintile (compared with fourth (p=0.003) and fifth (p=0.004) quintiles) of 25(OH)D levels, respectively.ConclusionLower vitamin D levels are associated with higher blood glucose values in Asian Indian women with pre-diabetes. These findings need confirmation in case–control and prospective studies.

Background and Objectives: Inadequate vitamin D and calcium intake have been linked to many health issues including chronic headaches. Some studies suggested an association between low vitamin D levels and increase the risk of frequent headaches in middle-aged and older men; however, no single study reported the role of these deficiencies in migraine patients. We aimed to investigate the association of hypocalcemia and vitamin D deficiency with migraine hospitalizations. Materials and Methods: A population-based retrospective cross-sectional analysis of the Nationwide Inpatient Sample (NIS) (years 2003–2014) in migraine hospitalizations was performed. The prevalence, demographic characteristics and All Patient Refined Diagnosis Related Groups severity/disability association were compared in patients with hypocalcemia and vitamin D deficiency to those without deficiencies, using ICD-9-CM codes. Weighted analyses using Chi-Square, paired Student’s t-test, and Cochran–Armitage trend test were performed. Survey logistic regression was performed to find an association between deficiencies and migraine hospitalizations and deficiency induced disability amongst migraineurs. Results: Between years 2003 and 2014, of the total 446,446 migraine hospitalizations, 1226 (0.27%) and 2582 (0.58%) presented with hypocalcemia and vitamin D deficiency, respectively. In multivariable analysis, hypocalcemia [Odds Ratio (OR): 6.19; Confidence Interval (CI): 4.40–8.70; p < 0.0001] and vitamin D deficiency (OR: 3.12; CI: 2.38–4.08; p < 0.0001) were associated with markedly elevated odds of major/extreme loss of function. There was higher prevalence (3.0% vs. 1.5% vs. 1.6%; p < 0.0001) and higher odds of migraine among vitamin D deficiency (OR: 1.97; CI: 1.89–2.05; p < 0.0001) patients in comparison to patients with hypocalcemia (OR: 1.11; CI: 1.03–1.20; p = 0.0061) and no-deficiency, respectively. Conclusions: In this study, we demonstrated a significant association between hypocalcemia and vitamin D deficiency with migraine attacks and deficiency induced loss of function among migraineurs. Early preventive measures may reduce the disability in migraineurs.

Background: Vitamin D deficiency is present in India in epidemic proportions despite plenty of sunshine. Reduced plasma 25(OH) D concentrations as a diagnostic marker of vitamin D deficiency have been in past decade associated with several well-established risk factors for ischaemic stroke, such as arterial hypertension, thrombosis, atherosclerosis. The aims and objectives of this study was to compare the serum 25(OH) D levels between the first ever acute stroke patients and healthy controls.Methods: A cross-sectional, case control study was conducted in a tertiary care hospital in New Delhi situated in north India. Serum 25‑hydroxyvitamin D (25(OH) D) levels in 85 patients of ischemic stroke, presenting within 7 days of onset of stroke was measured and was compared with 70 age and gender matched controls.Results: The mean age was 61.02±11.58 years and 58.63±11.28 years in cases and controls respectively. Females constituted 37.6% of the total number of cases and 43.4% of the controls. The age and gender-distribution were comparable between the cases and controls. The median value (IQR) of serum 25(OH) vitamin D level was 7.94 ng/mL (4.59-14.00) in the cases and it was 8.82 ng/mL (5.59-14.70) in the controls. The difference between the serum 25(OH) vitamin D levels of the two groups was not found to be statistically significant.Conclusions: There is a high prevalence of biochemical hypo-vitaminosis D in apparently healthy Indians of all age and sex groups despite adequate sunshine. There is no association between low vitamin D levels and stroke.

Abstract. We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20–29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = −0.280, p < 0.05; r = −0.407, p = 0.038; r = −0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [−0.413 ± 0.12, CI95 % (−0.659; −0.167), p = 0.006], whereas no significant association between hypertension [−1.005 ± 1.65, CI95 % (−4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [−0.44 ± 2.20, CI95 % (−4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

Background: In the recent years there has been an increased understanding of the role that vitamin D plays in regulation of cell growth, calcium absorption and immunity and its impact on the developing fetus and maternal health is of significant concern. This study aims at evaluating the Vitamin D status in pregnant women and their newborns.Methods: A cross sectional study was done on 100 pregnant females according to inclusion and exclusion criteria. At the time of delivery, maternal blood was collected, and newborn samples were taken from newborn side of umbilical cord and sent for analysis.Results: The prevalence of Vitamin D deficiency has been found to be 85% of pregnant females and 91% of the newborns. Only 5% of pregnant females and 1% of the newborns showed Vitamin D sufficiency. Maternal and newborn vitamin D levels show a positive correlation. Mean maternal and newborn Vitamin D levels were found to be 16.78±7.04 ng/mL and 11.29±5.75 ng/ml.Conclusions: Vitamin D deficiency is highly prevalent among pregnant women in north India. Low maternal vitamin D levels lead to vitamin D deficiency in the newborns also.

Objective: This study was aimed to determine the correlation between vitamin D and insulin resistance in women with PCOS. Method: This study was correlational analytic with cross-sectional approach to 34 women diagnosed with PCOS based on ultrasonography. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. Women with hormonal therapy and vitamin D supplementation were not included to this study. This study used consecutive sampling method. Result: The average of age was 25.6±6.1 years old. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. The average of waist circumference and FBG were 87.6±12.4 cm and 86.2±27.9 mg/dl, respectively. The mean of vitamin D levels was 11,5±3,6 ng/ml. According to Spearman’s correlation, vitamin D levels were weak negative correlated with waist circumference (r=-0.2; p>0.05) and FBG (r= -0,1; p>0,05), it statistically was not significant. Conclusion: There is weak negative correlation between vitamin D and metabolic syndrome in PCOS patients.

AbstractVitamin D deficiency is prevalent all over the world, especially in tropical countries. In epileptics, antiepileptic drugs (AED) and associated comorbidities further impact vitamin D status. The aim of this study is to estimate the prevalence of 25(OH) vitamin D deficiency in epileptic children and evaluate probable risk factors. A cross-sectional study of 200 children between 1 and 18 years of age on AED was undertaken in the pediatric neurology clinic of a tertiary care center of Northern India. In all children, serum 25(OH) vitamin D levels, calcium, phosphorus, and alkaline phosphatase were estimated. The deficiency levels of vitamin D were categorized as: deficiency <20 ng/mL, insufficiency 20 to 30 ng/mL, and sufficiency >30 ng/mL. The potential risk factors for hypovitaminosis D, including type of epilepsy, AED regimen (specific medications, polytherapy vs. monotherapy), cerebral palsy, ambulatory status, intellectual disability, body mass index, gender, and vegetarianism were examined. Among the 200 enrolled children (60% boys), 106/200 (53%) were vitamin D deficient. There was no significant relation of vitamin D levels with gender, type of epilepsy, neurological deficit, and type of AED. An inverse relationship of higher phenytoin doses during monotherapy associated with lower vitamin D levels in monotherapy was found, thereby suggesting adverse effect of high doses of phenytoin on vitamin D levels. VDD is common among epileptic children on AED therapy. Vitamin D deficiency is common prevalent among epileptic children on AED therapy, and its detection and treatment correction should be an integral part of epilepsy management.

Objectives To assess serum 25-hydroxycholecalciferol (25-OH vitamin D) levels in Jordanian children with bronchial asthma, and to examine correlations between 25-OH vitamin D levels and asthma severity and control. Methods A cross-sectional study was conducted at the Paediatric Chest Clinic, Al-Karak Governmental Hospital, Southern Jordan, between May 2015 and February 2016. Serum 25-hydroxyvitamin D level was determined in children aged 1–14 years diagnosed with bronchial asthma (6–14 years) or recurrent wheezing episodes (<6 years). Asthma severity was determined based on the Global Initiative for Asthma assessment, the Asthma Control Test, and the Childhood Asthma Control Test. Demographic and clinical characteristics were compared between patients with low and normal 25-OH vitamin D levels, and correlations between asthma severity and 25-OH vitamin D level were assessed. Results Out of 98 included children, 25-OH vitamin D levels were deficient and insufficient in 41 (41.8%) and 34 (34.7%) children, respectively. Only 23 (23.5%) had sufficient 25-OH vitamin D levels. A significant correlation was found between severity of asthma symptoms and 25-OH vitamin D deficiency. Conclusion 25-OH vitamin D deficiency is highly prevalent in Jordanian children with bronchial asthma and correlates significantly with asthma severity.

Objective: To study the Prevalence of Vitamin D deficiency in pregnant women. Study Design: A Cross-sectional analyticalstudy through convenient sampling technique. Setting and duration: At a private Clinic located at East Canal Road Faisalabad, from March2011 to June 2011. Material and method: The study included consecutive 61 pregnant women of reproductive age and non-pregnant womenwere excluded. Blood samples were taken in morning i.e. overnight fasting samples, by venepuncture by disposable syringes sample weretaken and samples were stored at -20 degree centigrade till they were analyzed. Our interest was in age and serum Vitamin D 3 levels. Results:Out of 61 pregnant women results showed that 87.0% pregnant women were having Vitamin D deficiency, 10.0% were having Vitamin Dinsufficiency, 3.0% had Vitamin D sufficiency and none shows Vitamin D intoxication. Vitamin D deficiency was more prevalent in pregnantwomen of younger age group. Furthermore prevalence was higher among the pregnant mothers with high parity. Moreover, 65% women werenot exposed to sunlight properly, 60% women had muscle cramps and bony aches. 90% women never were tested for tested Vitamin D levelsbefore. Conclusions: Prevalence of Vitamin D deficiency is significant in pregnant women. It is also important for its effects on various organsand systems of body as well as on pregnancy and neonate. The different aspects of study led to conclusion to emphasize that Health educationbe imparted to pregnant women and their families in terms of diet, proper sunlight exposure and taking Vitamin D supplements in pregnancy. It isthus recommended to perform Vitamin D levels in every pregnant woman.

Abstract Background: Current studies suggest that vitamin D deficiency during pregnancy can produce a certain effect for preterm birth, but there is no research showing whether vitamin D deficiency has a consistent effect in different pregnancies; thus, we conducted a systematic review and meta-analysis of 24 observational studies, grouping them according to the gestational age at the time of serum sampling, to investigate whether vitamin D deficiency in different periods of gestation has different effects on preterm birth and to provide an evidence-based basis for pregnant women to measure and supplement vitamin D. Methods: The databases PubMed-Medline, EMBASE, the Cochrane Library, Web of Science, EBSCO, CBM, and CNKI were searched until July 2019. Two researchers independently assessed the eligibility and quality of studies, and STATA 12.0 software was used for meta-analysis. Result: Seven cohort studies, 13 case-control studies, and four cross-sectional studies were included from 2500 articles by inclusion and exclusion criteria. After adjusting for age, race, and other confounding factors, meta-analysis results showed that vitamin D deficiency in the first trimester, the second trimester and the third trimester did not increase the risk of preterm birth (odds ratio (OR) = 1.01, 95% confidence interval (CI) (0.88, 1.16), P = 0.867; OR = 1.12, 95%CI (0.92, 1.37), P = 0.249; OR = 1.05, 95%CI (0.87, 1.27), P = 0.602). However, there was moderate heterogeneity in the study of vitamin D deficiency in the second trimester, and subgroup analysis suggested that vitamin D deficiency in the second trimester may increase the risk of preterm birth (OR = 1.33, 95%CI (1.15, 1.54), P = 0.000). A sensitivity analysis of the second trimester showed that excluding any one study did not significantly change the results. Conclusions: Vitamin D deficiency in early and late pregnancy may not be associated with preterm birth, while vitamin D deficiency in middle pregnancy is likely to have an important effect on preterm birth. Vitamin D levels should be measured in the second trimester of pregnancy, and vitamin D supplements should be provided if necessary.
