Abstract Background : Vitamin D insufficiency and deficiency in childhood are common. However, the status and influential factors of vitamin D during different ages are not clear. This study aimed to survey vitamin D concentrations in children aged 0 to 6 years and explore its influential factors. Methods: A total of 6953 children were recruited in Wuxi City of East China from January to December in 2016. Enzyme-linked immunosorbent assay was used to determine the serum concentrations of 25-hydroxyvitamin D [25(OH)D]. Results: The median vitamin D concentrations in the infant group (0-1 years of age) was 69.40 nmol/L, which were higher than that in both the toddlerhood group (1-3 years of age; 62.30 nmol/L) and the preschool group (3-6 years of age; 50.85 nmol/L). In addition, the median vitamin D concentrations were 71.70 nmol/L in summer, which was higher than that in spring (64.25 nmol/L), autumn (62.95 nmol/L) and winter (64.10 nmol/L). However, no difference was observed between genders ( P = 0.974). Furthermore, the prevalence of vitamin D deficiency (<50 nmol/L) was 48.1% in the preschool group (3-6 years of age), which was higher than the 21.2% vitamin D deficiency in the toddlerhood group (1-3 years of age) and the 17.9% vitamin D deficiency in the infant group (0-1 years of age). Interestingly, a nonlinear association between 25(OH)D and air temperature was observed. Conclusions: A high prevalence of vitamin D deficiency was common in a Chinese population of children 0-6 years old, especially in the preschool-aged children. Therefore, we suggested that we should pay more attention to vitamin D supplementation in Chinese young children.

Conclusions: A high prevalence of vitamin D deficiency was common in a Chinese population of children 0-6 years old, especially in the preschool-aged children. Season and air temperature were related to vitamin D status. Therefore, we suggest that the recommendation for vitamin D supplementation in the Chinese pediatric population should be revised to include preschoolers and adolescents.

AbstractThe incidence of vitamin D deficiency is high globally, and vitamin D supplementation draws particular attention. The objective of this study was to investigate the effects of stratified vitamin D supplementation in middle-aged and elderly individuals with vitamin D insufficiency in Beijing. A total of 448 subjects aged over 40 years old were selected from a community in Beijing. Among them, 100 middle-aged and elderly people with vitamin D insufficiency were randomly selected on a voluntary basis. They were further divided into control group and intervention group. The control group received health education and lifestyle guidance, and the intervention group received lifestyle guidance and vitamin D supplementation for nine months. The doses were stratified as follows: for vitamin D insufficiency, oral vitamin D3 supplement was given at 5000 IU/w; for mild vitamin D deficiency, oral vitamin D3 supplement was given at 10 000 IU/w; for severe vitamin D deficiency, oral vitamin D3 supplement was given at 15 000 IU/w. Safety evaluation was conducted after three-month treatment. The intervention group consisted of 8%, 62%, and 30% of cases who had vitamin D insufficiency, mild vitamin D deficiency, and severe vitamin D deficiency, respectively, which were similar with the control group. It showed that the blood 25(OH)D level increased significantly in the intervention group, from 14.30±4.30 ng/ml to 33.62±6.99 ng/ml (p<0.001), in contrast to insignificant change in the control group. Stratified vitamin D supplementation effectively increased the blood 25(OH)D level, as well as the number of cases with corrected vitamin D insufficiency or deficiency.

Background: Vitamin D deficiency remains the most common cause of rickets globally and is highly prevalent in developing countries including India. This study aimed to compare the efficacy of vitamin D and calcium together with calcium alone on growth parameters of children with vitamin D deficiency in community based setting.Methods: A randomized controlled trial was conducted in community based setting in Kanpur district. Multistage random sampling technique was used to select a total of 395 children between 2 years to 5 years from 5 villages of block Vidhunu. Of these, 138 children were randomized into two groups using balanced block randomization technique. Group 1 received vitamin D with calcium together and group 2 received calcium alone for a period of 12 months. Anthropometry, serum vitamin D, calcium, alkaline phosphatase levels were estimated at baseline and after 12 months. Data was analyzed using SPSS 20. Student’s t test was used to analyze the differences in growth and laboratory parameters in the two groups. Multiple linear regression analysis was used to assess the effect of various factors on the growth parameters.Results: Prevalence of vitamin D deficiency was 78.7%. Baseline characteristics of both groups were similar. After 12 months, group 1 demonstrated significantly greater improvement in weight SD score (21.4%) and height SD score (10.3%) and growth velocity (9.1 cm/year) compared to group 2 (14.3%, 7.8% and 6.9 cm/ year respectively). Also subjects in group 1 showed significantly greater improvement in serum levels of vitamin D, calcium and alkaline phosphatase than group 2.Conclusions: Vitamin D supplementation along with calcium improves the growth of children. Regular supplementation of all children with vitamin D can be considered as a policy for prevention of malnutrition.

AimsTo audit the investigation, identification and treatment of Vitamin D deficiency within Men's Secure Services.BackgroundVitamin D and/or vitamin D deficiency has been suggested to play a role in the pathogenesis of mental illness. There is evidence that Vitamin D inadequacy is pandemic among rehabilitation patients in inpatient settings. Patients within secure hospitals are similarly considered to be at high risk, due to their limited solar exposure during often lengthy admissions. It has been suggested that these patients should be considered an ‘at-risk’ cohort, for whom Vitamin D supplementation should be routine. Men's secure services in Birmingham comprise of two medium secure units and a low secure rehabilitation unit. Here we present an audit of Vitamin D monitoring and treatment completed in 2019.MethodA three year retrospective review of electronic patient records, for all inpatients admitted within men's secure services as of 1 September 2019 (n = 188). Standards were based on the Trust accepted guidelines for management of Vitamin D deficiency.ResultKey findings included:- The majority of inpatients were Caucasian (43%) and African-Caribbean (24%). Ages ranged from 18 to 70, with a mean age of 39.Approximately two-thirds (65%) had been in hospital for over a year, of which 44% had been admitted for more than 3 years. The average length of admission was 885 days.Only 47% of patients had their Vitamin D level checked within the study period.Of those checked, 24% were tested within 1 month of admission. The mean duration between admission and Vitamin D testing was 464 days.Results ranged from 10.3 to 118.5nmol/L. A high rate of Vitamin D deficiency was identified (54%), whilst a further 16% had ‘inadequate’ levels.23% of those identified as requiring treatment did not receive any supplementation, whilst 59% of those with sufficient Vitamin D were prescribed treatment.Only 48% had their levels rechecked following treatment; of these, only 59% now had an adequate Vitamin D status.ConclusionThis audit demonstrates limited Vitamin D monitoring within male forensic inpatients. There was a high prevalence of Vitamin D insufficiency in this population, yet a substantial proportion of patients with identified deficiency were not prescribed any treatment. Ongoing monitoring and review of treatment effectiveness was poor. We argue that more consideration should be given to this population, with robust guidelines introduced for the treatment of this specific ‘at-risk group’.

Background: Preeclampsia (PE) is a disease specific to pregnancy affecting many bodily systems. This is characterized by high blood pressure and proteinuria after the 20th week of pregnancy. The objective of this study was to evaluate of association of vitamin D insufficiency with gestational hypertension in pregnant women.Methods: This was a cross-sectional study. A total of 104 pregnant women were included in the study. The diagnosis of gestational hypertension was confirmed using the “Report of the American College of Obstetricians and Gynaecologists’ Task Force on Hypertension in Pregnancy” criteria. Based on these criteria, patients with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg (measured after a period of rest of four hours, twice daily) and proteinuria (≥300 mg protein/24 h) were diagnosed as gestational hypertension.Results: Vitamin D deficiency was found among 78.9% (90/114) women. There was no significant (p >0.05) difference in age of women between vitamin D deficient and sufficient. Vitamin D level was significantly (p = 0.0001) lower among the women between Vitamin D deficient (15.93±4.66) and sufficient (35.70±3.25). There was no significant (p >0.05) association of Vitamin D level with parity, family history of hypertension, blood pressure, gestational age and fasting blood glucose. There was significant (p = 0.0001) difference in BMI between Vitamin D deficient (30.10±4.95) and sufficient (24.04±2.75). Tobacco consumption was also associated with the level of Vitamin D. There was significant negative correlation between BMI and Vitamin D level (r = -0.56, p = 0.00011).Conclusions: The present study demonstrates that vitamin D plays a role in the ethology and pathophysiology of gestational hypertension. Among the population having the risk of vitamin D deficiency, the risk of pregnancy induced hypertension may be decreased through vitamin D supplementation.

Aims. Kidney disease was found to be a major risk factor for vitamin D deficiency in a population study of patients hospitalized. The aims of the study were to describe the prevalence of vitamin D deficiency inpatients and outpatients in a nephrology department during fall and to evaluate effect of assessing serum 25-hydroxyvitamin D (25(OH)D) levels and previous supplementation of cholecalciferol on vitamin D status.Methods. We studied 280 subjects in total, between October and January. The subjects were recruited from the following two groups: (a) inpatients and (b) outpatients in nephrology unit. We examined previous documentary evidence of vitamin D supplementation of the patients.Results. The prevalence of vitamin D deficiency among these 280 patients was 62,1% (174 patients). Fifty-three patients (18.9%) had severe vitamin D deficiency, 121 patients (43.2%) moderate vitamin D deficiency, and 66 patients (23.6%) vitamin D insufficiency. In logistic regression analysis female gender, not having vitamin D supplementation history, low serum albumin, and low blood urea nitrogen levels were significant independent predictors of vitamin D deficiency while no association of vitamin D deficiency with diabetes mellitus, serum creatinine, eGFR, and being hospitalized was found.Conclusion. Vitamin D deficiency, seems to be an important problem in both inpatients and outpatients of nephrology. Monitoring serum 25(OH)D concentrations regularly and replacement of vitamin D are important. Women in Turkey are at more risk of deficiency and may therefore need to consume higher doses of vitamin D.

Abstract Objectives The primary objective was to test whether rapid correction of insufficient vitamin D status initiated in the neonatal period improves whole-body lean mass across infancy. Methods This was a double-blinded, parallel-group, randomized controlled trial (NCT02563015). Healthy term breastfed infants of appropriate weight for gestational age (AGA) were recruited from Montreal (March 2016–2019). Capillary blood was collected (24–36 h) for serum 25-hydroxyvitamin D [25(OH)D] measurement (Liaison, Diasorin Inc.). Infants with serum 25(OH)D &lt; 50 nmol/L were randomized to receive 400 (group 1, n = 49) or 1000 IU/d (group 2, n = 49) until 12 mo of age. Those with 25(OH)D ≥ 50 nmol/L were recruited to form a reference group, receiving 400 IU/d (group 3, n = 41). Anthropometry, body composition (dual-energy x-ray absorptiometry), and 25(OH)D concentrations were assessed at 1, 3, 6, and 12 mo. Differences between trial and reference groups were tested using mixed model repeated measures ANOVA adjusting for maternal pregnancy weight gain, infant sex, skin color, actual age at assessment, and breastfeeding status. Data are mean ± SD. Results Infants (81 males, 58 females) were 39.6 ± 1.0 wk GA and 3388 ± 372 g at birth. By design, infants in group 1 and 2 had lower serum 25(OH)D concentrations at birth compared to group 3 (31.1 ± 9.3, 34.4 ± 12.0 vs. 68.0 ± 13.2 nmol/L, respectively, P &lt; 0.0001). On average, both trial groups achieved and maintained vitamin D sufficiency (25(OH)D ≥ 50 nmol/L) from 3 to 12 mo. Lean mass was not different among groups at baseline, but at 12 mo was higher in group 2 compared to group 1 (7012.5 ± 904.6 vs. 6690.4 ± 1121.7 g, P = 0.0075; 4.8% difference), and not different from the reference group (7012.5 ± 904.6 vs. 6715.1 ± 784.6 g, P = 0.2882). Weight, length, and whole-body fat mass were not different among groups at any time-point. Conclusions Vitamin D supplementation (400 and 1000 IU/d) corrects insufficient stores, whereas the higher dosage of 1000 IU/d, modestly increases lean mass of otherwise healthy AGA term born infants by 12 mo of age without altering weight or length. These data concur with observations in weanling rats where increased vitamin D intakes elevated lean mass. The long-term benefits require further research.

Introduction. The course of physiological pregnancy is provided by many complementary factors. Thus, a deficiency in one of the links of the metabolic network contributes to the development of an imbalance in the work of the whole organism, which ensures the growth and development of the embryo from the first days of gestation. It has been proven that vitamin D can act as an immune regulator during implantation, providing a protective effect in whole period of pregnancy.Aim. The aim of this study is assessed the features of the course of pregnancy in patients with different levels of vitamin D in the blood in the first trimester.Materials and methods. A prospective multicenter randomized study was conducted in the North-West region of the Russian Federation among 88 pregnant women in the first trimester of gestation (up to 13 weeks). All patients were divided into 3 groups depending on the initial level of vitamin D (group 1–14 women with a 25(OH)D < 10 ng/ml, group 2–62 pregnant women from 10 to 30ng/ml, group 3–12 pregnant women with a vitamin D content > 30 ng/ml).Results. In group 1.86% of patients with severe vitamin D deficiency were diagnosed with threatened miscarriage, which is significantly higher than in group 3 (85.7% and 33.3%, χ2 = 7.490, p = 0.007). At the same time, retrochorial hematoma in group 1 occurred 3.5 times more often than in group 3 (57.1% and 16.67%, respectively, χ2 = 4.473, p = 0.035). Subsequently, every 4th woman from the group with vitamin D deficiency gave birth earlier than expected, which was not observed among patients from group 3 (25%, 0%, χ2 = 1.231, p = 0.268).Conclusion. Prescribing cholecalciferol vitamin replacement therapy as part of complex preserving therapy for threatening miscarriage, followed by monitoring its blood level and deviating from normal parameters, contributing to a favorable course of pregnancy and improving perinatal outcomes.
