<b><i>Introduction:</i></b> Vitamin D deficiency and obesity have been classified as pandemic issues worldwide with high prevalence of both the risk factors in the United Arab Emirates. In recent years, obesity has been associated with vitamin D deficiency, but very few studies have been published about the correlation between them in the UAE population. <b><i>Subjects and Methods:</i></b> This is a cross-sectional study designed to find a correlation between vitamin D deficiency and obesity along with other metabolic factors. Data were collected from electronic medical records of 300 subjects ranging from 15 to 85 years of age of various ethnic origins residing in Dubai. <b><i>Results:</i></b> The study showed a high prevalence of obesity (44.9%) and vitamin D deficiency (40.1) in our study population. There is no evidence of a relation between vitamin D level and the obesity; 40.1% of the subjects were vitamin D deficient, out of which 46.7% were obese. However, a statistically significant relationship was found between cholesterol levels and vitamin D levels. Similarly, a significant relation was found between decreasing Vitamin D levels and increasing age but no relationship was detected with gender. <b><i>Conclusions:</i></b> The present study revealed an alarming prevalence of obesity and vitamin D deficiency. Further steps need to be taken to tackle this growing problem.

Background: Despite plenty of sunlight, vitamin D deficiency has been reported in both urban and rural population in India. This study was conducted to estimate the prevalence of Vitamin D deficiency in children between 3-6 years of age group belonging to Mananthavady ICDS block of Wayanad and to identify the sociodemographic variables affecting its level.Methods: This descriptive cross-sectional study was conducted from December 2014 to June 2015. 140 children were selected from 20 Anganawadis in Mananthavady ICDS block in Wayanad district of Kerala state by random methods. After taking relevant history and conducting detailed clinical examinations, blood samples were taken to assess 25(OH) Vitamin D, calcium, phosphorous and alkaline phosphatase levels. Statistical analysis was done using PASW software. Calculations of means were done using descriptive statistics and comparative analysis was done using independent T test.Results: Out of the 140 children 51 belonged to tribal community. The mean 25(OH) Vitamin D level was 22.7ng/ml. 47.1% of the population had deficient, 35% insufficient and 17.9% adequate Vitamin D levels. There was no statistically significant difference in Vitamin D levels between children of tribal and non-tribal community. There was significant increase in Vitamin D levels during summer when compared to that of winter and autumn seasons.Conclusions: There is a high prevalence of vitamin D deficiency among the rural children of 3-6-year age of Mananthavadi ICDS block. The Vitamin D levels were almost equal between the tribal and non-tribal children. Vitamin D levels are significantly higher during summer when compared to other seasons.

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.

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.

Objectives: The purpose of this study is to assess the Vitamin D deficiency awareness and perceptions between the United Arab Emirates (UAE) population. Methods: A cross-sectional study was done among the population of two emirates at the UAE: Abu Dhabi and Sharjah. Results: Overall, 434 participants completed the survey. Majority of people were aware of phenomenon of Vitamin D deficiency, but only 21.4% of them knew that sunlight is considered the main source of Vitamin D. Moreover, less than half of participants check their Vitamin D blood level regularly and around 55% of them follow-up with their physicians after completing the treatment. High proportion of participant females spend <1 h outdoors (60%) and use sunscreen daily (55%) that cause higher prevalence of Vitamin D deficiency among females than males (83% vs. 42%). Conclusion: This research gives some insights regarding the UAE population’s awareness and perceptions of Vitamin D insufficiency. Decreased awareness of sunlight exposure as a major source of Vitamin D, in addition to lifestyle, contributed to Vitamin D deficiency problem among the UAE population, in general, and in females, in particular.

Background: Recently, we see in our clinical practice that many patients who are coming with generalized body aches and pains and diagnosed as fibromyalgia or chronic fatigue, not adequately responding to treatment. When their vitamin D level was done, it was found to be low and correction of their low vitamin D level improved their symptoms dramatically. Despite abundant sunshine in Bangladesh, allowing vitamin D synthesis all the year round, why our people are developing hypovitaminosis D inspired us to do this current study. Our present study is designed to estimate the prevalence of vitamin D deficiency among adult patients presented with aches & pains as well as to study the association of low vitamin D levels with different socio-demographic parameters.Methods: A cross sectional observational study was conducted among 212 adult patients aged 18 years and above presented with generalized body aches and pains, attended both outpatient and inpatient departments of Popular Medical College Hospital during the period of March’16- August’16 ( 6 months). Association between vitamin D status & the individual specific variables was statistically analyzed.Results: The prevalence of vitamin D deficiency among the study population was found to be100% in all age groups. Among 212 study population, 73.6% were female (n=156) & 26.4% were male (n=56). Mean Vitamin D level among male was 14.29 (SD 4.68) & among female was 12.64 (SD 4.74). The factors associated with severely deficient Vitamin D level were female sex, urban population, &obesity. It is alarming that 64.2% of our study population were totally unaware about the importance of sun exposure.Conclusions: Vitamin D status was associated with a number of socio-demographic variables. Knowledge of these variables may improve targeted education and public health initiatives.J MEDICINE Jan 2018; 19 (1) : 22-29

This cross-sectional study enrolled 180 patients at a private family practice in Virginia. Total serum vitamin D concentrations were obtained weekly from January 30, 2013, through March 30, 2013, in consecutive patients regularly scheduled for laboratory work at the practice. Patients were categorized into 2 groups and analyzed for variant alleles in vitamin D receptor ( VDR; rs2228570), cytochrome P450 2R1 ( CYP2R1; rs10741657), 7-dehydrocholesterol reductase ( DHCR7; rs12785878), and group-specific component ( GC; rs2282679) to determine whether variants of those alleles influenced total serum 25(OH)D concentrations. One-hundred and eighty patients were enrolled, with 40 (22%) being sufficient, 25-hydroxy vitamin D level 25(OH)D ≥ 30 ng/mL, and 140 (78%) being insufficient, 25(OH)D < 30 ng/mL. Of the 4 genes, 2 genes, CYP2R1 (rs10741657) and GC (rs2282679), demonstrated a significant association related to vitamin D status. Subjects with 1 or more variant alleles at rs10741657 were almost 3.7 (odds ratio [OR] 3.67; 95% confidence interval [CI]: 1.35-9.99) times more likely be insufficient in vitamin D and subjects with 1 or more variant alleles at rs2282679 were about half (OR 0.42; 95% CI: 0.18-0.93) as likely to be insufficient in vitamin D. Allelic variations in CYP2R1 (rs10741657) and GC (rs2282679) affect vitamin D levels, but variant alleles on VDR (rs2228570) and DHCR7 (rs12785878) were not correlated with vitamin D deficiency, 25(OH)D < 30 ng/mL.

Vitamin D Levels

Abstract Objectives Obesity has been identified as a risk factor for vitamin D deficiency. Those seeking bariatric surgery for obesity treatment have an additional risk for low vitamin D levels post-op due to factors that affect compliance with taking supplemental vitamins and minerals. As personalized nutrition (PN) may change behaviors and have an impact on health outcomes, this study will examine the relationships among genetic variants that predispose individuals to vitamin D deficiency, PN, knowledge of the risk of vitamin D deficiency, and supplemental vitamin adherence in patients who have undergone bariatric surgery. Methods This will be a one year cross-sectional study with approximately 50 participants with severe obesity having bariatric surgery. Inclusion criteria will include subjects aged 18 years and older seeking sleeve gastrectomy at The Advanced Bariatric Surgery Center in Lubbock, Texas. Exclusion criteria will be those who are not candidates for surgery and nicotine, alcohol, and/or drug dependency. The data collected will include buccal swab genetic tests, two assays for vitamin D receptor (VDR) single polymorphisms (SNPs), vitamin D levels, diet and vitamin and mineral adherence, and dual-energy X-ray absorptiometry (DEXA) scans. This information will be analyzed and compared to patients’ outcomes at pre-op and post-op appointments. Results N/A. Conclusions Upon completing this study, we expect to have identified how micronutrient genetic testing can be used in conjunction with PN to improve the bariatric surgery population's vitamin D levels. This outcome can further nutrition education and PN to improve overall health knowledge and interventional outcomes on critical nutritional parameters. Furthermore, the results could potentially produce greater adherence to vitamin and mineral regimens, and improve bone density among individuals who have undergone bariatric surgery. Funding Sources This study was funded by start-up funds from Texas Tech University.
