The health effects of vitamin D are well documented, with increasing evidence of its roles beyond bone. There is, however, little evidence of the effects of vitamin D on hospitalisation among older adults. This study aimed to prospectively determine the relationship of vitamin D status in older adults with hospital admission and emergency department (ED) attendance. Trinity University of Ulster Department of Agriculture (TUDA) is a large cross-sectional study of older adults with a community population from three disease-defined cohorts (cognitive dysfunction, hypertension, and osteoporosis). Participants included in this analysis were recruited between 2008 and 2012. ED and hospital admission data were gathered from the date of TUDA participation until June 2013, with a mean follow up of 3.6 years. Of the 3093 participants, 1577 (50.9%) attended the ED during the period of follow-up. Attendees had lower mean serum 25(OH)D concentrations than non-attendees (59.1 vs. 70.6 nmol/L). Fully adjusted models showed an inverse association between vitamin D and ED attendance (Hazard Ratio (HR) 0.996; 95% Confidence Interval (CI) 0.995–0.998; p < 0.001). A total of 1269 participants (41%) were admitted to hospital during the follow-up. Those admitted had lower mean vitamin D concentrations (58.4 vs. 69.3 nmol/L, p < 0.001). In fully adjusted models, higher vitamin D was inversely associated with hospital admission (HR 0.996; 95% CI 0.994–0.998; p < 0.001) and length of stay (LOS) (β = −0.95, p = 0.006). This study showed independent prospective associations between vitamin D deficiency and increased hospitalisation by older adults. The need for further evaluation of current recommendations in relation to vitamin D supplementation, with consideration beyond bone health, is warranted and should focus on randomised controlled trials.

Aim: The study aim was to assess the association of vitamin D supplementation before hospital admission and severe outcomes in subjects admitted for COVID-19.Methods: We performed a cross-sectional analysis of pseudonymised medical record data from subjects admitted to the Hospital de la Santa Creu i Sant Pau (Barcelona, Spain) for COVID-19 during March and April 2020. The composite primary study outcome was defined as death and/or invasive mechanical ventilation (IMV). Association between risk factors and study outcomes was evaluated by bivariate analysis, followed by logistic regression analysis.Results: In total, 1,267 persons were hospitalised during the observation period. Overall, 14.9% of the subjects were on active vitamin D supplementation treatment before admission. The subjects in the vitamin D group were significantly older than subjects without vitamin D supplementation. We observed higher rates of the primary outcome (death and/or IMV) among the persons with previous use of vitamin D (30.1 vs. 22.9% in those not receiving treatment). In the bivariate analysis, previous use of vitamin D was positively associated with death and/or IMV [odds ratio (OR): 1.45 95% CI: 1.03; 2.04]; however, after adjustment for other risk factors this association disappeared (OR: 1.09 95%CI: 0.65; 1.81).Conclusion: We did not find an association between vitamin D supplementation before hospital admission and death and/or IMV in subjects admitted for COVID-19. The age and the burden of age-associated comorbidities were independently associated with the in-hospital events.

Background Multiple Sclerosis is associated with low serum levels of 25-hydroxyvitamin D (25(OH)D). We investigated the association between serum levels of 25(OH)D and 1,25-dihydroxyvitamin D (1,25(OH)2D), the biologically active metabolite, and clinical MS severity as expressed by EDSS-score and relapse rate. Study-design Cross-sectional study. Patients and Methods Serum samples from 267 MS patients were collected for 25(OH)D and 1,25(OH)2D measurement. Clinical MS parameters at the date of serum sampling were determined. Results: Both metabolite levels were significantly lower in the progressive forms compared to the relapsing remitting (RR)MS phenotype. In RRMS patients (disease course ≤ 5 years), high 25(OH)D levels were associated with a high chance of remaining relapse-free. Low 25(OH)D levels were associated with high EDSS-scores. 1,25(OH)2D was not directly associated with relapse rate or EDSS-score, and was dependent of age and 25(OH)D level. Conclusion Serum levels of 25(OH)D were associated with both relapse rate and disability in MS patients. These results are suggestive for a disease modulating effect of the serum concentrations of 25(OH)D on MS. The low circulating 1,25(OH)2D levels in progressive MS are due to older age and lower 25(OH)D levels. The potential consequences for vitamin D supplementation in MS will be discussed.

Previous studies have not been able to show with certainty the effect of vitamin D supplementation in tuberculosis patients. The objective of this study is to determine whether vitamin D supplementation to patients with tuberculosis could influence 25-hydroxyvitamin D (25(OH)D) and calcium serum levels. The results, after 28 days, the vitamin D supplementation showed significant increase of 25(OH)D serum level at the end point (p=0.001), but not for the calcium serum level (p=0.3). The Conclusions is supplementation with 1,000 IU vitamin D per day increased the 25(OH)D serum level but there was no association with the calcium serum level.

Introduction: Vitamin D deficiency has been linked to a whole spectrum of diseases including osteoporosis, cancer, diabetes, and cardiovascular and immune disorders. Though Bangladesh is low latitude country, vitamin D Deficiency is serious and wide spread problem in Bangladesh. Physicians of Bangladesh are more vulnerable to low vitamin D status due to long indoor work hours and lack of sunlight exposure in both government & private institute. So, the aim of this study to evaluate vitamin D status among the physicians working around the Bangladesh. Methods: This was a cross-sectional, multicenter study where we enrolled 1112 doctors from 9 different areas of Bangladesh from May 2018 to June 2019. A Blood sample was collected from all participants to measure Serum 25(OH)D and various patient data such as age, gender, BMI, physical activity level during leisure time, use of vitamins and medications, sunlight exposure time, tea/coffee drinking, smoking, H/O comorbidities etc. was collected. Results: Of the 1112 doctors assessed in the study,794 (71.4%) was male and 318 (28.6%) was female. Mean age of the participants was 45.5±11.1 Years. Vitamin D deficiency and insufficiency was found in 734 (65.8%) and 105 (9.4%) participants respectively. Mean vitamin D level was 18.9 ng/ml (±8.6 ng/ml). Less than 5% of participants of Rajshahi, Rangpur, Dhaka, Bogura and Sylhet had sufficient vitamin D level. Vitamin D deficiency was significantly associated with age, obesity, sunlight exposure, physical inactivity, hypertension and vitamin D supplementation. Conclusion: Vitamin D deficiency is very common among physicians of all over Bangladesh. The high prevalence of vitamin D deficiency in the present study points towards urgent need of an integrated approach to detect vitamin D deficiency among health care professionals and treat appropriately.

AbstractBackgroundVitamin D deficiency is common in older adults and has been linked with frailty and obesity, but it remains to be studied whether frail obese older adults are at higher risk of vitamin D deficiency. Therefore, the aim of this study is to explore the association between frailty, adiposity indices and serum 25(OH)D concentrations.Methods1447 individuals with 65 years or older, participating in a cross-sectional study (Nutrition UP 65). Frailty, according to Fried et al., body mass index (BMI), waist circumference (WC), body roundness index (BRI) and body shape index (ABSI) were evaluated. A stepwise multinomial logistic regression was carried out to quantify the association between 25(OH)D quartiles and independent variables.ResultsMedian 25(OH)D levels were lower in individuals presenting both frailty and obesity (p<0.001). In the multivariate analysis, pre-frailty (OR 2.65; 95% CI 1.63-4.32) and frailty (OR 3.76; 95% CI 2.08-6.81) were associated with increased odds of lower 25(OH)D serum levels (first quartile). Regarding adiposity indices, obesity (OR 1.75; 95% CI 1.07-2.87) and the highest categories of WC (OR 3.46; 95% CI 1.95-6.15), BRI (OR 4.35; 95% CI 2.60-7.29) and ABSI (OR 3.17 95% CI 1.86-5.38) were directly associated with lower 25(OH)D serum levels (first quartile).ConclusionsA positive association between frailty or obesity and lower levels of vitamin D was found. Moreover, besides BMI and WC, other indicators of body adiposity, such as BRI and ABSI, were associated with lower 25(OH)D serum concentrations.

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.

Previous research suggests prevalent vitamin D deficiency in pregnant women residing in South Australia and the Eastern Seaboard, however recent data from Perth, Western Australia (WA) is lacking. This cross-sectional study ofn=209 pregnant women (36–40 weeks of gestation, 84% white Caucasian) reports on the vitamin D (25[OH]D) status of a contemporary population of pregnant women in Perth, WA, with a focus on the relative contributions of supplemental vitamin D and ambient ultraviolet (UV) radiation to 25(OH)D levels. Mean (SD) season-adjusted 25(OH)D levels were 77.7 (24.6) nmol/l. The prevalence of vitamin D deficiency (25[OH]D<50 nmol/l) was 13.9%. Ambient UV radiation levels in the 90 days preceding blood draw were significantly correlated with serum 25(OH)D levels (unstandardized coefficient 2.82; 95% CI 1.77, 3.86,P<0.001). Vitamin D supplementation expressed as dose per kg of body weight was also positively correlated with serum 25(OH)D levels (unstandardized coefficient 0.744; 95% CI 0.395, 1.092,P<0.001). In conclusion, this study finds that vitamin D deficiency in a predominantly white Caucasian cohort of pregnant women is less prevalent than has been reported in other studies, providing useful information relating to supplementation and screening in this, and similar, populations.

Abstract Objective The study aimed to assess the association between parental-reported vitamin D supplementation and caries in a national sample of 3-year-olds in Poland. Materials and methods A total of 1900 children, representing all provinces of Poland, were invited. The questionnaires concerned vitamin D supplementation, socio-demographics, and oral health behaviours. Based on dental examination, caries scores (dmft/dmfs), prevalence of early childhood caries (ECC) and severe ECC (S-ECC) were calculated. The Spearman’s correlation, linear regression and logistic regression were used to assess the association between various factors and caries (p < 0.05). Results A total of 1638 children were tested. Of this number, 99.1% infants were supplemented with vitamin D. Supplementation had been continued seasonally in 55.2% children. ECC/S-ECC prevalence were significantly lower in children receiving vitamin D (ECC 38.3% vs. 44.7%, OR = 0.77; S-ECC 20.5% vs. 27.1%, OR = 0.69; p < 0.05). Mean dmft/dmfs were lower in those with supplementation (1.54 ± 2.72 vs. 2.24 ± 3.55; 2.40 ± 5.56 vs. 3.72 ± 7.56, respectively; p < 0.001). After controlling for confounding factors, supplementation was not significantly associated with caries; only dt/ds were still associated. Maternal education, sweetened beverages before bedtime, bottle use were significantly associated with S-ECC. Conclusions Lower caries prevalence was observed in those with vitamin D supplementation. The association between parental-reported vitamin D and ECC/S-ECC was not significant in Polish children. Decayed teeth and supplementation were still associated. Dietary habits can modify the association with caries. Clinical relevance There may be an association between vitamin D supplementation and lower caries in children. Parents should supplement their children during periods of significant growth and development.

Abstract Background Sarcopenia is a geriatric syndrome associated with negative health outcomes and the use of viable alternative screening tools may help in the diagnosis of this condition. This study aimed to analyze the association of sarcopenia with anthropometric indicators among community-dwelling older adults and to identify cut-off points for such indicators as a discriminant criterion for predicting sarcopenia. Methods This was a cross-sectional study conducted on community-dwelling older adults ≥60 years old (n = 411) of both sexes from Macapá, Amapá, Brazil. Socioeconomic, clinical and anthropometric data (arm circumference - AC, waist circumference - WC, calf circumference - CC and body mass index – BMI) were collected using a structured form. Sarcopenia was identified according to the EWGSOP 2 consensus. The association between anthropometric indicators and sarcopenia was performed using logistic regression and cut-off points established from the ROC Curve. Statistical significance was defined as p ≤ 0.05. Results Adjusted analysis indicated an independent and inverse association between sarcopenia and the anthropometric indicators: AC (odds ratio, OR: 0.63; 95% confidence interval, 95%CI: 0.53–0.76), CC (OR: 0.73; 95%CI: 0.62–0.85), WC (OR: 0.93; 95%CI: 0.90–0.97) and BMI (OR: 0.64; 95%CI: 0.53–0.76). The following cut-off points for older men and women represented the discriminant criterion for the presence of sarcopenia: WC (≤97 and ≤ 86 cm), CC (≤33 and ≤ 31 cm), AC (≤27 cm) and BMI (≤24.8 kg/m2 and ≤ 24.5 kg/m2) (area under the ROC curve superior to 0.70). BMI and AC were the indicators with the highest ability to discriminate older adults of both sexes with sarcopenia. Conclusions An increase of one unit of the indicators can reduce the probability of occurrence of sarcopenia. All indicators were considered to discriminate the occurrence of sarcopenia, with emphasis on BMI and AC, and could be used to screen for this condition among community-dwelling older adults.
