Objectives: To determine the association between low maternal serum vitamin D and gestational diabetes mellitus (GDM) among Filipino women in St. Luke’s Medical Center – Quezon City. Methodology: A cross-sectional study involving pregnant women at outpatient clinics in a tertiary hospital in the Philippines. Simultaneous testing for fasting blood sugar, 75g oral glucose tolerance test and serum vitamin D was done. Participants were classified as GDM versus non-GDM, and normal versus low serum vitamin D. Univariate and multivariate statistics were done to determine relationship between vitamin D and GDM. Results: Of 211 included women, 198 (93.8%) had low vitamin D levels, and 56 (26.5%) had GDM. Vitamin D was significantly higher in the GDM group (21.0±8.1 vs 18.8±5.3 ng/mL, p=0.0189). The proportion of women with low vitamin D levels was significantly higher among those without GDM (96.1% vs 87.5%, OR=0.28, p=0.029]. After adjusting for age, parity, history of GDM and pre-pregnancy BMI, no significant association was observed (adjusted OR=0.66, p=0.522). No correlation was seen between vitamin D and FBS (r=0.28, p=0.095), 1-hour post-75 g OGTT (r=0.26, p=0.643), and 2-hour post-75 g OGTT (r=0.28, p=0.113). Conclusion: There was an association found between maternal serum vitamin D level and GDM in the univariate analysis, but none was evident after adjusting for possible confounders. The unanticipated high prevalence of low vitamin D levels among pregnant Filipinos needs to be verified in future studies.

Thyroid hormones have a catabolic effect on bone homeostasis. Hence, this study aimed to evaluate serum vitamin D, calcium, and phosphate and bone marker levels and bone mineral density (BMD) among patients with different thyroid diseases. This cross-sectional study included patients with underlying thyroid diseases (n = 64, hyperthyroid; n = 53 euthyroid; n = 18, hypothyroid) and healthy controls (n = 64). BMD was assessed using z-score and left hip and lumbar bone density (g/cm2). The results showed that the mean serum vitamin D Levels of all groups was low (<50 nmol/L). Thyroid patients had higher serum vitamin D levels than healthy controls. All groups had normal serum calcium and phosphate levels. The carboxy terminal collagen crosslink and procollagen type I N-terminal propeptide levels were high in hyperthyroid patients and low in hypothyroid patients. The z-score for hip and spine did not significantly differ between thyroid patients and control groups. The hip bone density was remarkably low in the hyperthyroid group. In conclusion, this study showed no correlation between serum 25(OH)D levels and thyroid diseases. The bone markers showed a difference between thyroid groups with no significant difference in BMD.

Introduction: Circulating vitamin D concentrations have been associated with the risk of type 2 diabetes (T2D). Magnesium has also been reported to be associated with lower T2D risk. Besides, magnesium is an essential cofactor for vitamin D activation. However, the effect of dietary magnesium intake on the association between vitamin D and the risk of T2D has not been studied comprehensively. Therefore, we designed this cross-sectional study to assess the effect modification of magnesium intake on the association between vitamin D and risk of T2D.Research Design and Methods: The present study analyzed data from the National Health and Nutrition Examination Survey (NHANES) continuously from 2007 to 2014, involving 10,249 participants. By having stratified participants based on magnesium intake category (low magnesium intake &lt;267 mg/day; high magnesium intake: ≥267 mg/day), we further evaluated the difference (interaction test) between the relationship of vitamin D with the risk of T2D among low magnesium intake participants and high magnesium intake participants using weighted multivariable logistic regression.Results: In this cross-sectional study, the association of serum vitamin D with the incidence of T2D appeared to differ between the low magnesium intake group and the high magnesium intake group (OR: 0.968, 95%Cl: 0.919–1.02 vs. OR: 0.925, 95%Cl: 0.883–0.97). Furthermore, there was evidence of interaction between vitamin D levels and magnesium intake on decreasing the incidence of T2D (p-value for interaction = 0.001).Conclusions: The results of our study indicated that magnesium intake might affect the association of serum vitamin D with the risk of T2D. Such a finding requires further randomized controlled trials to provide more evidence.

BACKGROUND Global prevalence of paediatric asthma has shown a sharp increase in last three decades. Recently vitamin D has been linked with lung function and vitamin D supplementation can lessen the acute exacerbations in asthmatic children. The purpose of the study was to compare lung parameters and vitamin D levels in asthmatic and non-asthmatic children and assess the correlation between vitamin D levels and pulmonary function parameters in children. METHODS A cross-sectional study was conducted among 40 asthmatic children and 42 healthy volunteers between the age group of 5 and 18 years attending the paediatric outpatient department (OPD) in a tertiary care centre in Coimbatore. Pulmonary functions were assessed using computerized spirometer and the serum 25-hydroxy vitamin D levels were estimated by Diazyme EZ vitamin D assay latex enhanced immunoturbidimetric method. The results were compared between asthmatics and non-asthmatics to find out the association. RESULTS The average age of the study participants was 10.5 ± 2.5 years. Lung parameters and mean vitamin D levels are reduced in asthmatics. There is a positive significant correlation between serum vitamin D levels and forced expiratory volume FEV1 / forced vital capacity (FVC) (P < 0.05, r = 0.781), and also between vitamin D and FEV1 (P < 0.05, r = 0.28). Lung parameters like FEV1, FEV1 / FVC ratio and peak expiratory flow rate (PEFR) are significantly decreased in asthmatic children. CONCLUSIONS Majority of the asthmatics have insufficient vitamin D levels than the normal peers with no asthma. Our study confirms the positive association between vitamin D and FEV1 and FEV1 / FVC ratio. KEYWORDS Vitamin D, Asthma, Pulmonary Function, Lung Parameters

Abstract Background: Low serum vitamin D concentrations have been reported to be associated with an increased risk of non-alcoholic fatty liver disease (NAFLD). However, whether slim or obese people show a similar association between vitamin D and NAFLD remains speculative. This study aimed to explore the relationship between serum vitamin D concentrations and NAFLD in lean and obese Chinese adults.Methods: This cross-sectional study included 2538 participants (1360 men and 1178 women) who underwent their health checkups at the First Affiliated Hospital of Zhejiang University School of Medicine in 2019. NAFLD was diagnosed by liver ultrasound excluding other causes. The association of serum vitamin D concentrations with NAFLD was analyzed in lean and obese participants.Results: The overall prevalence of NAFLD was 33.61% (13.10% in lean and 53.32% in obese) in this study population. The serum vitamin D levels of obese NAFLD patients were lower than that of the obese NAFLD-free controls. However, the serum vitamin D levels of lean NAFLD patients were comparable to that of the lean NAFLD-free controls. Serum vitamin D levels were negatively correlated with the prevalence of NAFLD in obese but not lean participants. Serum vitamin D levels were independently associated with the risk of NAFLD in obese participants, with an adjusted odd ratio (95% CI) of 0.986 (0.979–0.992). However, the serum vitamin D levels were not related to the risk of NAFLD in lean participants.Conclusions: Low serum vitamin D levels are associated with NAFLD in obese but not lean participants.
