Background: The aim of this study was to assess the relationship between vitamin D status and the prevalence of dyslipidemia and impaired fasting glucose (IFG) in children. Methods and Summary: 284 children (150 boys and 134 girls) aged 9–11 were included in the study. Children with deficient 25(OH)D (25-hydroxycholecalciferol) levels ≤20 ng/mL (50 nmol/L) were characterized by a more frequent occurrence of impaired fasting glucose (IFG) (Odd ratios (OR) = 1.966, 95% confidence interval (CI): 1.055–3.663; p = 0.033) when compared to children with 25(OH)D >20 ng/mL. Serum 25(OH)D with concentration lower by 1 ng/mL (2.5 nmol/L) was linked to higher fasting glucose (by 0.25 mg/dL, 0.013 mmol/L; p = 0.017), higher total cholesterol (TC) by almost 1 mg/dL (0.96 mg/dL, 0.25 mmol/L; p = 0.006) and higher high-density lipoprotein cholesterol (HDL-C) (by 0.57 mg/dL, 0.015 mmol/L; p < 0.001). Conclusion: 25(OH)D deficiency may negatively affect fasting glucose and total cholesterol concentration in children aged 9–11. Vitamin D-deficient children are twice as likely to develop prediabetes as reflected by impaired fasting glucose when compared to those with a 25(OH)D level above 20 ng/mL (50 nmol/L).

Objective: To compare vitamin D status in, women with PCOS & fertile women without PCOS and its subsequent evaluation. Introduction: PCOS is an endocrine disorder of women in reproductive age, characterised by obesity, hyperandrogenaemia and insulin resistance. Women with PCOS tend to be overweight and have increased risk of development of Type II Diabetes and cardiovascular disease. Exact Etiology of PCOS still remain an enigmatic dilemma however various studies conducted till date include diet and lifestyle modification as the key factor to promote health, BMI, reduced hyperinsulinemia and reduce the risk of development of PCOS. Main aim of our study was to compare vitamin D status in women having PCOS, with fertile women in a tertiary care hospital in Uttarakhand. Methodology: The conducted study was cross sectional, involving the enrolment of 100 women comprising of 50 women with PCOS and 50 fertile women without PCOS. Participants were selected from gynaecological OPD at Shri Mahant Indiresh Hospital, associated with Shri Guru Ram Rai Institute of Medical Sciences, Dehradun from July 2019 to January 2020. The diagnostic criteria of PCOS used was the Rotterdam criteria. The serum 25-hydroxy vitamin D and other metabolic markers were measured. Vitamin D deficiency was defined as serum 25 (OH) D concentrations less than 20 ng/ml measured on an instrument named as miniVidas (BioMerieux, Germany) based on ELFA (enzyme linked fluorescent assay). Results: Serum 25-hydroxyvitamin D was significantly lower in women with PCOS compared to fertile controls (p< 0.0001), and the prevalence rates of 25(OH) D deficiency and insufficiency were higher in women with PCOS than in fertile women (p < 0.0001). The study results showed that the prevalence of 25 (OH) D deficiencies in PCOS women was significantly high. Serum 25 (OH) D concentrations were significantly negatively correlated with body mass index (BMI), waist-to-hip ratio (WHR), fasting insulin, total cholesterol and low-density lipoprotein cholesterol (LDL-C), (P < 0.05). In comparison, serum 25 (OH) D concentrations were significantly positively correlated with high-density lipoprotein cholesterol (HDL-C) (P < 0.05). Increased BMI and WHR, high levels of fasting insulin, total cholesterol and LDL-C were regarded as risk factors, but high level of HDL-C was considered to be protective factor of vitamin D deficiency in PCOS women. Conclusion: The study demonstrated that women with PCOS have a significantly lower 25(OH) D compared to fertile controls. A compromised vitamin D status in PCOS women is associated with a higher prevalence and metabolic risk of PCOS in women.

AbstractObjectiveTo investigate whether low vitamin D status was related to insulin resistance (IR) or impaired fasting glucose (IFG) in Korean adolescents, after adjusting for total body fat mass (FM).DesignA cross-sectional study.SettingKorea National Health and Nutrition Examination Survey (KNAHNES) 2009–2010.SubjectsIn total, 1466 participants (769 males) aged 10–19 years were assessed for serum 25-hydroxyvitamin D (25(OH)D) levels, for FM by whole-body dual-energy X-ray absorptiometry and for IR by homeostasis model assessment (HOMA-IR) after an 8 h fast.ResultsAge-, sex-, season- and physical-activity-adjusted regression models showed that serum 25(OH)D levels were significantly related to markers of adiposity (P = 0·016 for FM (g), P = 0·023 for FM (%) and P = 0·035 for fat mass index). When the participants were stratified into three 25(OH)D categories (<37·5 nmol/l (n 553), 37·5 to < 50 nmol/l (n 543) and ≥ 50 nmol/l (n 370)), significantly decreasing trends were observed for fasting insulin (all P < 0·001), HOMA-IR (all P < 0·001) and the odds ratios for IFG (all P for trend < 0·05) from the lowest to the highest 25(OH)D category, after adjustments for age, sex, physical activity and all markers of adiposity. In the multivariate logistic regression analysis, the likelihood of participants in the lowest serum 25(OH)D category having IFG was 2·96–3·15 compared with those in the highest 25(OH)D category (all P < 0·05).ConclusionsThere was a significant inverse relationship between vitamin D status and IR and the risk of IFG, independent of adiposity, in Korean adolescents.

Background: Vitamin D deficiency is an unrecognized epidemic found in India and also worldwide. Despite the high prevalence of diabetes among Indians, there is a paucity of data showing the relationship between vitamin D status and cardiometabolic disparities. In this study, we have examined the relationship between vitamin D and cardiometabolic traits in a population from India. Methods: Circulating 25(OH)D levels were measured in 3,879 participants from the Asian Indian Diabetic Heart Study using ELISA kits. Results: Vitamin D levels were significantly reduced (p < 0.0001) in both men and women with obesity. However, compared to women, serum vitamin D was consistently lower in men (p < 0.02), irrespective of the presence of obesity and type 2 diabetes. Multivariate regression revealed strong interaction of vitamin D with body mass index that resulted in increased fasting glucose (p = 0.001) and reduced homeostasis model assessment of β-cell function (HOMA-B; p = 0.01) in normoglycemic individuals. However, in gender-stratified analysis, this association was restricted to men for both fasting glucose (p = 2.4 × 10-4) and HOMA-B (p = 0.001). Conclusions: Our findings suggest that vitamin D deficiency may significantly enhance the risk of cardiometabolic disease among Asian Indians. Future randomized trials and genetic studies are expected to clarify the underlying mechanisms for gender differences in vitamin D deficiency, and whether vitamin D-driven improvement in testosterone may contribute to beneficial cardiometabolic outcomes in men.

Abstract Context: Bread can potentially be a suitable vehicle for fortification with vitamin D. Objective: This study was undertaken to evaluate the following: 1) the bioavailability of vitamin D from the fortified Iranian bread and 2) the possible effects of daily consumption of the fortified bread on certain health aspects. Design, Setting, and Participants: This was a randomized, double-blind, placebo-controlled trial conducted over 8 weeks in 90 healthy subjects aged 20–60 years. Intervention: Subjects were randomly allocated to one of three groups: 1) fortified bread (FP; 50 g bread fortified with 25 μg vitamin D3 plus placebo daily; n = 30); 2) supplement (SP; 50 g plain bread plus 25 μg vitamin D supplement daily; n = 30); and 3) control (CP; 50 g plain bread plus placebo daily; n = 30). Outcome Measures: Initial and final anthropometric and biochemical assessments were performed. Results: The within-group changes of serum 25-hydroxyvitamin D concentrations were 39.0 ± 22.6 (P &lt; .001), 28.9 ± 31.2 (P &lt; .001), and −9.2 ± 12.3 nmol/L in the FP, SP, and CP groups, respectively. Only in FP and SP groups, serum intact PTH concentrations decreased approximately 13.5% and 14.5%, respectively. Visceral fat also showed a significant decrement in FP (−1.05% ± 1.4%; P ≤ .001) and SP (−0.96% ± 1.7%; P = .006). Serum low-density lipoprotein cholesterol concentration showed a within-group reduction in FP (−10.4 ± 11.2 mg/dL; P &lt; .001) and an insignificant decrement in SP (−6.6 ± 20.2 mg/dL; P = .083). Serum high-density lipoprotein increased in both vitamin D-supplemented groups (FP: 9.7 ± 7.6 vs SP: 5.7 ± 6.7 mg/dL; P &lt; .001). Conclusion: Vitamin D-fortified bread could be potentially effective in raising circulating 25-hydroxyvitamin D levels of the population to nearly adequate levels.
