AbstractObjective:Both vitamin D and Fe micronutrient deficiencies are common in Saudi Arabia but the association between them is unclear. The present study aimed to determine whether Fe indices are associated with vitamin D status and other metabolic markers in Arab adolescents.Design:Single-centre, cross-sectional study gathering anthropometrics, glucose and lipid profile. Serum 25-hydroxyvitamin D (25(OH)D), Fe, total iron-binding capacity (TIBC), transferrin saturation (%) and other parameters were measured.Setting:Vitamin D School Project Database, King Saud University (2014–2016).Participants:Arab adolescents aged 10–17 years randomly selected from the Vitamin D School Project Database (170 Saudi students; 100 girls, seventy boys).Results:Among Fe indices, only TIBC was found to be significantly and inversely associated with 25(OH)D (r = −0·20; P < 0·01) and only in girls (r = −0·20; P < 0·05). Among cardiometabolic parameters, serum Fe was associated with TAG in boys (r = 0·36; P < 0·01) and inversely associated with HDL-cholesterol in girls (r = −0·29; P < 0·05). Age was the most significant predictor of serum Fe for all participants, accounting for 5 % (R2 = 0·05; P = 0·004) of variance perceived. Serum 25(OH)D and age, on the other hand, were the most significant predictors for TIBC, accounting for 10·1 % (R2 = 0·10; P < 0·001) of variance perceived.Conclusions:Among healthy Arab adolescents, the association between vitamin D and Fe indices, particularly TIBC, is modest, inverse and sex-dependent. Larger studies with inclusion of markers such as hepcidin and ferritin, vitamin D metabolites and endogenous sex hormones may provide a clearer view of this complex association.

Micronutrient deficiencies and stunting are known as a significant problem in most developing countries, including Indonesia. The objective of this study was to analyze the association between micronutrient deficiencies and stunting with socioeconomic status (SES) among Indonesian children aged 6–59 months. This cross-sectional study was part of the South East Asian Nutrition Surveys (SEANUTS). A total of 1008 Indonesian children were included in the study. Anemia, iron deficiency, vitamin A deficiency, vitamin D deficiency, and stunting were identified in this study. Structured questionnaires were used to measure SES. Differences between micronutrient parameters and anthropometric indicators with the SES groups were tested using one-way ANOVA with post-hoc test after adjusted for age, area resident (rural and urban), and sex. The highest prevalence of anemia, stunting, and severe stunting were found to be most significant in the lowest SES group at 45.6%, 29.3%, and 54.5%, respectively. Children from the lowest SES group had significantly lower means of Hb, ferritin, retinol, and HAZ. Severely stunted children had a significantly lower mean of Hb concentration compared to stunted and normal height children. Micronutrient deficiencies, except vitamin D, and stunting, were associated with low SES among Indonesian children aged 6–59 months.

Study Design: Cross-sectional study. Objectives: Thus, this study aimed to assess the epidemiological profile of a patient sample that underwent spinal surgery regarding their nutritional and vitamin D status. Methods: Serum albumin and vitamin D (25-hydroxyvitamin D) levels were measured in patients with different spinal surgical approaches and various pathologies at a single institution. 112 patients were retrospectively identified for inclusion and stratified by age into 4 age groups and by pathology. The nutritional status of the patients was classified in vitamin D inadequacy (< 30ng/mL), vitamin D deficiency (<20ng/mL), and hypoalbuminemia (<3.5g/dL). Data was analyzed comparing vitamin D, and albumin means considering gender, age group, and pathologies. Results: Twenty-eight (25.2%) patients had hypoalbuminemia. There was no difference between gender (p = 0.988); there was a significant decrease in albumin concentration increasing the age (p < 0.001). The prevalence of hypoalbuminemia was significantly higher in patients with trauma, tumor and infection than in those patients with degenerative and deformity diseases (p = 0.003). The prevalence of vitamin D inadequacy was 33.7%, and that of deficiency was 62.2%, while severe deficiency (< 10 ng/mL) in 16.3%. The vitamin D concentration was significantly different among the pathologies (P = 0.047), the lower concentration occurring in patients with tumor. Conclusion: Older patients, as well as patients with tumor and infectious pathologies, seem to have a higher prevalence of hypoalbuminemia, inferring malnutrition. There was a low epidemic level of vitamin D concentration, almost all patients presenting some degree of hypovitaminosis D, independent of age, gender and nutritional status.

Background: Authors examined serum vitamin D status among the healthy school children belonging to the south Indian state of Kerala.Methods: A cross-sectional study, participants were recruited through medical camps organized in Thrissur and Palakkad districts of central Kerala during the months of March and April 2017. A 174 healthy school children (98 males and 76 females) aged 5-13 years were recruited for the study. The children were found to be healthy on the basis of physical examination by a Paediatrician. None of the children had any symptoms of skeletal deformities. All the children were drug-naive. Data on height, weight, skin color, food habits, physical activities and socio-economic status were recorded. A 2ml of peripheral blood samples were collected from the participants. Total vitamin D in the serum was estimated by chemiluminescence immunoassay (CLIA).Results: VDD was observed in 60.92% and insufficiency in 30.46% of the participants. Only 8.62% of the participants had normal vitamin D levels. The mean vitamin D level was 19.93 ng/ml. Males had significantly higher vitamin D levels compared to females. Factors such as age, height, weight, diet, skin color and socio-economic status did not influence vitamin D levels.Conclusions: This is the first study of vitamin D status among the school-age children of Kerala. This paper adds further evidence to the reports indicating high prevalence of subclinical VDD among children across India and calls for action.

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.
