Insufficient Vitamin D Status at Birth Is Corrected by Vitamin D Supplementation (1000 IU/Day) With Increases in Lean Mass Evident at 12 Months of Age in Healthy Term Infants

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 < 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 < 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.

Vitamin D Status

Abstract Objectives Vitamin D status is positively associated with lean mass phenotype in healthy infants born with sufficient vitamin D stores. The objective is to test whether rapid correction of low neonatal vitamin D status improves body composition (lean mass and fat mass) at 6 mo of age. Methods In a double-blinded randomized parallel group controlled trial (NCT02563015), healthy term neonates of appropriate weight for gestational age were recruited from Montreal. Capillary blood samples were collected 24–36 h post natally for measurement of serum 25-hydroxyvitamin D [25(OH)D] (Liaison, Diasorin Inc.). Infants with serum 25(OH)D < 50 nmol/L (n = 87) were randomized to receive 400 or 1000 IU/d until 6 mo of age. Those with 25(OH)D ≥ 50 nmol/L (n = 31) were recruited as a reference group, and received 400 IU/d. Anthropometry, lean mass and fat mass (dual-energy x-ray absorptiometry) were measured at baseline, 3 and 6 mo. Skin color was measured using a spectrophotometer. Differences between treatments and reference groups were tested using mixed model and repeated measures ANOVA accounting for the effects of sex, season of birth, skin color and gestational age (GA). Results Neonates (67 males, 51 females) were 39.6 ± 1wk GA and 3387 ± 371 g at birth. There were no differences between groups in lean mass or fat mass at baseline; nor in weight or length at any time-point. Combined treatment groups, had lower serum 25(OH)D concentrations at birth compared to the reference group (33 ± 11 vs. 69 ± 13 nmol/L, P < 0.0001). However, at 6 mo of age, serum 25(OH)D concentration was higher in the group receiving 1000 IU/d (n = 34), in comparison to the group receiving 400 IU/d (n = 29), and the reference (n = 19) group (125.0 ± 34.0, 82.2 ± 21.5 vs. reference 85.4 ± 32.1 nmol/L, P < 0.0001). Whole body lean mass was significantly different among groups (5071.3 ± 750.0, 4944.1 ± 616.3 and 5166.0 ± 645.4 g, respectively, P = 0.03), with infants in the treatment group provided a 400 IU/d supplement having a lower lean mass by 6 mo of age compared to the 1000 IU/d group. Fat mass was not different among groups following post-hoc testing (2967.0 ± 929.0 and 2962.0 ± 952.0, 2742.0 ± 754.0 g, P = 0.16). Conclusions Higher dosage supplementation of vitamin D rapidly improved vitamin D status and supported a leaner body phenotype in infancy. Funding Sources Canadian Institutes of Health Research.

Background. The objective of this quasi-experimental study was to determine whether bolus vitamin D supplementation taken either regularly over the preceding year or after the diagnosis of COVID-19 was effective in improving survival among hospitalized frail elderly COVID-19 patients. Methods. Seventy-seven patients consecutively hospitalized for COVID-19 in a geriatric unit were included. Intervention groups were participants regularly supplemented with vitamin D over the preceding year (Group 1), and those supplemented with vitamin D after COVID-19 diagnosis (Group 2). The comparator group involved participants having received no vitamin D supplements (Group 3). Outcomes were 14-day mortality and highest (worst) score on the ordinal scale for clinical improvement (OSCI) measured during COVID-19 acute phase. Potential confounders were age, gender, functional abilities, undernutrition, cancer, hypertension, cardiomyopathy, glycated hemoglobin, number of acute health issues at admission, hospital use of antibiotics, corticosteroids, and pharmacological treatments of respiratory disorders. Results. The three groups (n = 77; mean ± SD, 88 ± 5 years; 49% women) were similar at baseline (except for woman proportion, p = 0.02), as were the treatments used for COVID-19. In Group 1 (n = 29), 93.1% of COVID-19 participants survived at day 14, compared to 81.2% survivors in Group 2 (n = 16) (p = 0.33) and 68.7% survivors in Group 3 (n = 32) (p = 0.02). While considering Group 3 as reference (hazard ratio (HR) = 1), the fully-adjusted HR for 14-day mortality was HR = 0.07 (p = 0.017) for Group 1 and HR = 0.37 (p = 0.28) for Group 2. Group 1 had longer survival time than Group 3 (log-rank p = 0.015), although there was no difference between Groups 2 and 3 (log-rank p = 0.32). Group 1, but not Group 2 (p = 0.40), was associated with lower risk of OSCI score ≥5 compared to Group 3 (odds ratio = 0.08, p = 0.03). Conclusions. Regular bolus vitamin D supplementation was associated with less severe COVID-19 and better survival in frail elderly.

Aim of this study was to evaluate the effect of vitamin D supplementation in obese, insulin resistant and vitamin D deficient PCOS women on biochemical and clinical hyperandrogenism and menstrual irregularity in comparison to effect of metformin or combined metformin plus vitamin D therapy. Thirty nine PCOS women were randomized into three groups and treated with alfacalcidiol (Group 1), combined alfacalcidiol and metformin therapy (Group 2) and metformin (Group 3) for 6 months. Serum TST, fTST, DHEAS, LH and LH/FSH were measured before and after six months of treatment. Menstrual cycle regularity, hirsutism, acne and pregnancy rate were assessed at the same time. There was a significant decrease in TST levels in the Group 2 and slight but not significant decrease in the Group 3. No significant changes in other parameters (fTST, DHEAS, LH, LH/FSH) have been found after 6 months therapy in all three groups. An improvement of menstrual cycle was detected in 78 % of patients in Group 1 (p<0.04), 80 % in the Group 2 (p<0.03) and in 90 % in the Group 3 (p<0.002), respectively. There was no significant improvement of acne and hirsutism in all three groups (all p not significant). Pregnancy rate was higher in the Group 3 as compared with Groups 1 and 2 (67 % vs. 0 % and 25 %, respectively), however without statistical significance. Vitamin D administration has no significant effect on androgen levels and clinical features of hyperandrogenism in obese vitamin D deficient PCOS women. However, it can potentiate effect of metformin on testosterone levels and LH/FSH ratio but not on clinical hyperandrogenism and pregnancy rate.

Abstract Objectives To explore the associations between postpartum maternal vitamin D status and body composition to neonatal serum 25-hydroxyvitamin D (25(OH)D) and body composition. Methods Healthy mothers and term-born infants of appropriate size for gestational age were recruited from Greater Montreal (March 2016 through March 2019). The present analysis includes data from mothers and infants (n = 144). Maternal characteristics and lifestyle factors were surveyed and newborn capillary blood samples were taken within 36 h of delivery to assess vitamin D status using total serum 25(OH)D (Liaison, Diasorin). Maternal and infant anthropometry and body composition (Dual-energy X-ray absorptiometry) and maternal serum 25(OH)D were measured within 1 mo postpartum. Mothers were classified into 2 groups (group 1: ≥50 nmol/L; group 2: <50 nmol/L). Data were analyzed descriptively (mean ± SD or n (%)) and using a mixed model with Tukey post hoc tests accounting for neonatal sex, gestational age, season, family income, maternal age, education, and race. Correlation tests were used to identify linear relationships between continuous variables. Results Neonates (85 males, 59 females) were 39.7 ± 1.0 wk GA and 3393 ± 363 g at birth. Mothers (32.1 ± 4.5 years) in group 1 had considerably higher serum 25(OH)D concentrations compared to mothers in group 2 (80.3 ± 22.0 n = 96 vs. 38.7 ± 9.0 n = 48, nmol/L, P < 0.0001). Moreover, maternal serum 25(OH)D concentrations were positively associated with their % whole body lean mass (r = 0.28, P = 0.0009) and inversely associated with their % whole body fat mass (r = −0.25, P = 0.003). At birth, infants of mothers in group 1 had higher serum 25(OH)D concentrations compared to infants in group 2 (51.0 ± 18.1 vs. 27.0 ± 12.0 nmol/L, P < 0.0001), and were correlated with maternal 25(OH)D (r = 0.74, P < 0.0001). Maternal lean body mass and lean mass index (LMI) (kg/m2) explained some positive variations in infant lean body mass and LMI (Estimate = 0.01, P = 0.004; Estimate = 27.7, P = 0.04). Conclusions Higher maternal vitamin D status is associated with higher neonatal vitamin D with possible implications to neonatal lean body mass. This study reinforces the importance of ensuring adequate maternal-fetal transfer of vitamin D. Funding Sources Canadian Institutes of Health Research.

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.

The aim of this study was to investigate the cardiometabolic risk factors (CRFs) in community dwelling men based on a combination of body mass index (BMI) and waist circumference (WC). This cross-sectional study was based on 867 males between the ages of 20 and 71 years. Subjects were categorized into 4 groups by BMI and WC (Group 1, BMI < 25 kg/m2 and WC < 90 cm; Group 2, BMI < 25 kg/m2 and WC > 90 cm; Group 3, BMI > 25 kg/m2 and WC < 90 cm; and Group 4 BMI > 25 kg/m2 and WC > 90 cm). The proportion of subjects with a normal weight with high WC was 3.2%. Among normal weight men with the high range of WC, significantly high Odds ratios (ORs) and 95% CI were found for hypertriglyceridemia (3.8, 1.8–8.2) and high blood glucose (3.2, 1.5–6.9). The probability that the general obesity group (Group 3) had one CRF was around twice that of the reference group (Group 1) (1.9 to 2.1 times), but Group 2 had probability more than 4 times higher (4.3 to 4.6 times). In community dwelling adult men, normal weight with high waist circumference was associated with the highest cardiometabolic risk. In conclusion, follow-up screening of those with high WC may be necessary to detect and prevent cardiometabolic diseases, particularly for men with a normal weight.

Hypovitaminosis D is common in India. In the present prospective partially randomised study of vitamin D (D3) supplementation during pregnancy, subjects were randomised in the second trimester to receive either one oral dose of 1500 μg vitamin D3(group 1,n48) or two doses of 3000 μg vitamin D3each in the second and third trimesters (group 2,n49). Maternal 25-hydroxyvitamin D (25(OH)D) at term, cord blood (CB) alkaline phosphatase (ALP), neonatal serum Ca and anthropometry were measured in these subjects and in forty-three non-supplemented mother–infant pairs (usual care). Median maternal 25(OH)D at term was higher in group 2 (58·7, interquartile range (IQR) 38·4–89·4 nmol/l)v. group 1 (26·2, IQR 17·7–57·7 nmol/l) and usual-care group (39·2, IQR 21·2–73·4 nmol/l) (P = 0·000). CB ALP was increased (>8.02 μkat/l or >480 IU/l) in 66·7 % of the usual-care groupv. 41·9 % of group 1 and 38·9 % of group 2 (P = 0·03). Neonatal Ca and CB 25(OH)D did not differ significantly in the three groups. Birth weight, length and head circumference were greater and the anterior fontanelle was smaller in groups 1 and 2 (3·08 and 3·03 kg, 50·3 and 50·1 cm, 34·5 and 34·4 cm, 2·6 and 2·5 cm, respectively)v. usual care (2·77 kg, 49·4, 33·6, 3·3 cm;P = 0·000 for length, head circumference and fontanelle andP = 0·003 for weight). These differences were still evident at 9 months. We conclude that both 1500 μg and two doses of 3000 μg vitamin D3had a beneficial effect on infant anthropometry, the larger dose also improving CB ALP and maternal 25(OH)D.

Background: An increased hemoglobin (Hb) level may have detrimental effects on hepatic steatosis (HS) as well as cardiovascular disease (CVD). We investigated Hb's effect on incident ischemic heart disease (IHD) risk in the context of hepatic steatosis (HS).Methods: We assessed 17,521 non-diabetic participants and retrospectively screened for IHD using the Korea National Health Insurance data. High Hb was defined as Hb levels ≥16.3 g/dL in men and 13.9 g/dL in women (>75th percentile). The participants were divided into five groups: reference (group 1), mild HS only (group 2), mild HS and high Hb (group 3), severe HS only (group 4), and severe HS and high Hb (group 5). We assessed hazard ratios (HRs) with 95% confidence intervals (CIs) for IHD using multivariate Cox proportional hazards regression models over 50 months from the baseline survey.Results: During the follow-up period, 330 (1.9%) participants developed IHD (310 angina pectoris and 20 myocardial infarction). Compared with the reference group (group 1), the HRs for IHD were 1.04 (95% CI, 0.75–1.46) in group 2, 1.14 (95% CI, 0.70–1.85) in group 3, 1.58 (95% CI, 1.08–2.32) in group 4, and 1.79 (95% CI, 1.15–2.80) in group 5, after adjusting for IHD risk factors.Conclusions: We found the combined effect of HS and Hb levels on the incidence of IHD.

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.

Background: Osteoporosis is the most prevalent metabolic disease affecting bones. Objective: To investigate the long-term effect of pulsed electromagnetic field (PEMF) combined with exercise protocol on bone mineral density (BMD) and bone markers in men with osteopenia or osteoporosis. Methods: Ninety-five males with osteopenia or osteoporosis (mean age, 51.26 ± 2.41 years; mean height, 176 ± 2.02 cm; mean weight, 83.08 ± 2.60 kg; mean body–mass index (BMI), 26.08 ± 1.09 kg/m2) participated in the study, and they were randomly assigned to one of three groups: Group 1 received a full-body PEMF and exercise protocol (PEMF +EX), Group 2 received a placebo full-body PEMF and exercise protocol (PPEMF +EX), and Group 3 received a full-body PEMF alone (PEMF). PEMF was applied for the whole body using a full-body mat three times per week for 12 weeks, with an exercise protocol that includes flexibility, aerobic exercise, strengthening, weight-bearing, and balance exercises followed by whole-body vibration (WBV) training. Outcome measures include BMD of total hip and lumbar spine and bone markers [serum osteocalcin (s-OC), Serum amino-terminal cross-linking telopeptide of type I collagen (s-NTX), Serum carboxy-terminal cross-linking telopeptide of type I collagen (s-CTX), Parathyroid hormones (PTH), Bone-specific Alkaline Phosphatase (BSAP), and 25-hydroxy vitamin D (Vit D)]. Results: The BMD of total hip and lumbar spine was significantly increased post-treatment in all groups, and more so in Group 1 and Group 2 than Group 3. There was a significant difference in bone markers in all groups, more so in Group 1 and Group 2 than in Group 3. Conclusion: PEMF combined with exercise protocol exerts a potent role for treating OP, is more effective than exercise and PEMF alone for increasing BMD and enhancing bone formation, and suppresses bone-resorption markers after 12-weeks of treatment with the impact lasting up to 6 months.
