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.

The Impact

Vitamin D status was assessed in a large urban area to compare differences in deficiency and to geomap the results. In total, 36,466 participants from 28 geographical areas were identified in this cross-sectional, retrospective analysis of general practitioner (GP)-requested 25(OH)D tests at St James’s Hospital, Dublin between 2014 and 2018. The population were community-dwelling adults, median age 50.7 (18–109 years) with 15% of participants deficient (<30 nmol/L), rising to 23% in the winter. Deficiency was greatest in younger (18–39 years) and oldest (80+ years) adults, and in males versus females (18% vs. 11%, p < 0.001). Season was the biggest predictor of deficiency (OR 4.44, winter versus summer, p < 0.001), followed by location (west Dublin OR 2.17, north Dublin 1.54, south Dublin 1.42 versus rest of Ireland, p < 0.001) where several urban areas with an increased prevalence of deficiency were identified. There was no improvement in 25(OH)D over the 5-year period despite increased levels of testing. One in four adults were vitamin D deficient in the winter, with significant variations across locations and demographics. Overall this study identifies key groups at risk of 25(OH)D deficiency and insufficiency, thus providing important public health information for the targeting of interventions to optimise 25(OH)D. Mandatory fortification may be necessary to address this widespread inadequacy.

Abstract Background: The aim of this study was to investigate the vitamin D status and related factors in community-dwelling Korean stroke survivors. Methods: Data of 23,872 individuals ≥20 years who participated in the Korea National Health and Nutrition Examination Surveys (KNHANES) were analyzed. Participants who had ever been diagnosed with stroke by a doctor were defined as stroke survivors (n = 431). The serum 25-hydroxyvitamin D (25(OH)D) level was measured by radioimmunoassay, and vitamin D deficiency was defined as 25(OH)D <20 ng/mL. The association between vitamin D and stroke status was analyzed using multivariable general linear models and logistic regression models adjusted for sociodemographic and clinical covariates. Results: The adjusted mean 25(OH)D level of stroke survivors was significantly lower than that of nonstroke controls; however, after adjustment for SBP level and use of antihypertensive medication, the difference was no longer statistically significant. The burden of 25(OH)D deficiency was not higher in stroke survivors than in nonstroke controls (adjusted OR = 1.14; 95% CI, 0.81-1.62). Current smoking was independently associated with 25(OH)D deficiency among stroke survivors (adjusted OR = 3.17; 95% CI, 1.33-7.55). Conclusions: These findings indicated that treatment of high blood pressure and smoking cessation may be important measures to control vitamin D levels in stroke survivors.

AbstractA positive association has been reported between vitamin D status, muscle strength and physical function in older Caucasian women. However, little is known about this relationship in UK South Asian older women. This cross-sectional study aimed to explore the association between vitamin D status, muscle strength and physical function in UK South Asian (Pakistani and Indian) older women.One hundred and twenty community-dwelling women were recruited via visiting community centres, mosques, Indian temples (Gurdwara) and by word of mouth (between January to May 2018). Inclusion criteria were: community-dwelling, South Asian women, age 60 years and above, able to communicate effectively and able to give written or verbal consent. A general interview (demographic, anthropometric, self-reported exhaustion, health history, supplementation use/duration/dose), handgrip strength (kg), short physical performance battery (single chair stand, repeated chair stands, balance, timed up-and-go test), and blood 25 hydroxyvitamin D (25(OH)D, nmol/l) concentration were performed. Dietary intake and self-reported physical activity was also assessed using multiple-pass 24-hour diet recall method and International Physical Activity Questionnaire (IPAQ) short form respectively.Overall, 47% of participants had insufficient blood 25(OH)D concentration (< 50nmol/L) and 53% had sufficient blood 25(OH)D (≥ 50nmol/L) using the IOM classification. As expected 86% of current vitamin D supplement users had adequate vitamin D status and only 14% of women who reported current vitamin D supplement use had insufficient vitamin D status. Amongst supplement non-users 68% had insufficient vitamin D status and only 32% had adequate levels. An inverse correlation (Spearman's analysis) was found between vitamin D status and single chair stand test (sec) (r = -0.25, p = 0.006); repeated chair stand test (sec) (r = -0.29, p = 0.002) and timed up-and-go test (sec) (r = -0.20, p = 0.02). No correlation was observed between vitamin D status and handgrip strength (r = 0.09, p = 0.30).The prevalence of vitamin D insufficiency is high in post-menopausal South Asian women not taking vitamin D supplements. Significant association was observed between vitamin D status and some aspects of muscle strength and physical function. We are now conducting a randomized control trial to investigate whether vitamin D supplementation may restore muscle strength and function in this population.

We examined whether the −634C→G, 298C→T, and 2C→T polymorphisms of the IL-6, osteocalcin, and vitamin D receptor (VDR) genes, respectively, were associated, alone or in combination, with bone mineral density (BMD) in community-dwelling Japanese women (between 1108 and 1113) or men (between 1116 and 1130) aged 40–79 yr. The −634C→G polymorphism of the IL-6 gene and the 298C→T polymorphism of the osteocalcin gene were associated with BMD in postmenopausal women, with the respective GG and TT genotypes representing risk factors for reduced bone mass. IL-6 and osteocalcin genotypes showed additive effects on BMD for postmenopausal women. The 2C→T polymorphism of the VDR gene was associated with BMD in men, with the CT genotype contributing to reduced BMD. These results suggest that the IL-6 and osteocalcin genes are susceptibility loci for reduced BMD in postmenopausal women and that the VDR gene constitutes such a locus in men. The combined IL-6 and osteocalcin genotypes may prove informative for the assessment of osteoporosis in women.

Vitamin D Levels

Little published information is available regarding epidemiological data on vitamin D status in the large geographical region of Central Europe (CE). We searched the journal literature with regard to 25(OH)D concentrations among community-dwelling or healthy people living in CE. 25(OH)D concentrations varied by age, season, study sample size, and methodological approach [i.e., 25(OH)D assay used]. Concentrations of 25(OH)D in CE appeared lower than 30 ng/mL, and the magnitude of hypovitaminosis D was similar to that reported in Western Europe. While most of the studies reviewed were cross-sectional studies, a longitudinal study was also included to obtain information on seasonal variability. The longitudinal study reported wintertime 25(OH)D values close to 21–23 ng/mL for all studied age groups, with a significant increase of 25(OH)D in August reaching 42 ng/mL for those aged 0–9 years, but only 21 ng/mL for the elderly aged 80–89 years. The decrease in 25(OH)D with respect to age was attributed to decreased time spent in the sun and decreased vitamin D production efficiency. Based on the literature review on vitamin D status in the CE populations, it can be concluded that 25(OH)vitamin D levels are on average below the 30 ng/mL level.
