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.

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.

Objectives To evaluate the serum 25-hydroxyvitamin D [25(OH)D] concentration in Brazilian osteoporotic patients and the modifiable factors of vitamin D status in this population. Subjects and methods In a cross-sectional study, 363 community-dwelling patients who sought specialized medical care were evaluated between autumn and spring in São Paulo, Brazil. Serum levels of 25(OH)D and parathormone (PTH), biochemical and anthropometric measurements, and bone density scans were obtained. The group was assessed using two questionnaires: one questionnaire covered lifestyle and dietary habits, skin phototype, sun exposure, medical conditions, and levels of vitamin D supplementation (cholecalciferol); the other questionnaire assessed health-related quality-of-life. Logistic regression and a decision tree were used to assess the association between the variables and the adequacy of vitamin D status. Results The mean age of the overall sample was 67.9 ± 8.6 years, and the mean 25(OH)D concentration was 24.8 ng/mL. The prevalence of inadequate vitamin D status was high (73.3%), although 81.5% of the subjects were receiving cholecalciferol (mean dose of 8,169 IU/week). 25(OH)D was positively correlated with femoral neck bone mineral density and negatively correlated with PTH. In the multivariate analysis, the dose of cholecalciferol, engagement in physical activity and the month of the year (September) were associated with improvement in vitamin D status. Conclusions In this osteoporotic population, vitamin D supplementation of 7,000 IU/week is not enough to reach the desired 25(OH)D concentration (≥ 30 ng/mL). Engagement in physical activity and the month of the year are modifiable factors of the vitamin D status in this population.

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.

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.

Purpose. As the vitamin D status of Algerian postmenopausal women was poorly described, this cross-sectional study investigated the prevalence of low vitamin D status in a sample population. Secondarily, predictive factors of this hypovitaminosis D were explored.Methods. All the 336 selected women ≥ 45 years from Douera were interviewed to get anthropometric and lifestyle data, reproductive and medical history, medications, and calcium/vitamin D intakes. A blood sample was collected to measure 25-hydroxyvitamin D (25(OH)D) concentrations.Results. Approximately 86% of subjects had low vitamin D status (<20 ng/mL). Mean 25(OH)D level was 14.4 ± 5.3 ng/mL with a clear seasonal dynamic and a significant negative correlation with PTH levels (r  = −0.15,p=0.006). A multiple regression analysis using the 25(OH)D cutoff value of 17 ng/mL instead of the generally admitted level of 20 ng/mL was performed to increase statistical power. Other seasons than summer (OR 4.159 and 95% CI 2.456–7.043), obesity (≥30 kg/m2, OR 1.826, 95% CI 1.081–3.083), and veiling (OR 3.526, 95% CI 1.090–11.400) were significantly associated with 25(OH)D concentrations <17 ng/mL.Conclusions. In North Algeria, the abundant sunlight appears insufficient to fully offset hypovitaminosis D risk factors in postmenopausal women, especially obesity and veiling. It suggests the major need to increase vitamin D supplementation in this subpopulation.

Background: The possibility of vitamin D deficiency is high among mothers and their premature newborns. Objectives: Due to the high rate of vitamin D deficiency in Iranian women, this study aimed to determine the association between the serum levels of vitamin D in the blood of premature newborns and their mothers in the Iranian population. Methods: This cross-sectional study was conducted on 324 mothers and their 324 newborns with gestational age less than 37 weeks, who were referred to Ghaem Hospital affiliated to Mashhad University of Medical Sciences, Mashhad, Iran, during 2016-2020. After clamping, 1.5 cc blood samples were obtained through the umbilical cord to determine the neonates’ vitamin D levels. Finally, the serum levels of vitamin D were measured, and the correlation between the levels of vitamin D of mothers and their newborns was calculated. Results: The mean vitamin D levels of newborns and mothers were 15.75 ± 11.18 and 20.16 ± 13.41 ng/mL, respectively. Moreover, there was a high correlation between the vitamin D levels of mothers and their newborns (r = 0.672; P < 0.001). Furthermore, a significant correlation was observed between the vitamin D levels of mothers, who used vitamin D supplementation during pregnancy and their neonates’ levels (r = 0.773; P < 0.001). Conclusions: The findings suggest a positive correlation between neonatal and maternal vitamin D levels. Moreover, it seems that maternal vitamin D levels can predict neonatal vitamin D deficiency.

Objective Post-menopausal nocturia is poorly understood. This study aimed to identify hormonal and lifestyle factors associated with nocturia and to understand the relative contribution of altered urine production and bladder storage dysfunction in women. Design, setting, population and methods Women ≥40 years presenting to public continence services were enrolled in a cross-sectional study. 153 participants completed a hormone status questionnaire, a validated nocturia causality screening tool and a 3-day bladder diary. Descriptive statistics and logistic regression models for nocturia severity and bladder diary parameters were computed. Results Overall, 91.5 % reported nocturia, 55% ≥2 /night. There was a difference of 167.5 mL (p<0.001) in nocturnal urine volume between women with nocturia ≥2 (median 736mL) vs less often (517mL). Significant predictors of self-reported disruptive nocturia were age (OR 1.04, 95%CI 1.002-1.073) and vitamin D supplementation (OR 2.33, 95%CI 1.11-4.91). Nocturnal polyuria was significantly more common with nocturia ≥2 compared to less often (p<0.002). 150 minutes of exercise per week was protective for nocturnal polyuria (OR 0.22, p=0.001). Nocturia index >1.3 was significantly predicted by age (OR 1.07, p<0.001), regular exercise (OR 0.41, p=0.036), day flushes (OR 4.00, p=0.013) and use of Vitamin D (OR 2.34, p=0.043). Maximum voided volumes were significantly lower with nocturia≥2 vs less often (night: 268ml vs 350mL; day: 200mL vs 290mL). Conclusions Bothersome nocturia in post-menopausal women is associated with changes to both nocturnal diuresis and bladder storage. Regular physical activity, prolapse reduction and oestrogen replacement may be adjunctive in managing bothersome nocturia in women.
