Evidence on the effect of ambient air pollution on vitamin D is limited. This study aimed to examine the association of air pollution exposure with serum levels of 25-hydroxyvitamin D (25OHD) using UK Biobank health datasets. A total of 448,337 subjects were included in this analysis. Land Use Regression was applied to assess individual exposures to particulate matter with diameters ≤2.5 µm (PM2.5), ≤10 µm (PM10), nitrogen dioxide (NO2), and nitrogen oxides (NOx). Linear regression models evaluated the associations between air pollutants and serum vitamin D levels after adjustment of a series of confounders. All analyzed air pollutants were negatively associated with serum vitamin 25OHD levels. After adjusting for potential confounders, a 10 μg/m3 increase in concentrations of PM2.5, PM10, NOx, and NO2 was associated with −9.11 (95%CI: −13.25 to −4.97), −2.47 (95%CI: −4.51 to −0.43), −0.56 (95%CI: −0.82 to −0.30), and −1.64 (95%CI: −2.17 to −1.10) nmol/L decrease in serum vitamin 25OHD levels, respectively. Interaction analyses suggested that the effects of air pollution were more pronounced in females. In conclusion, long-term exposures to ambient PM2.5, PM10, NOx, and NO2 were associated with vitamin D status in a large UK cohort.

Knowledge Attitude And Practice

Abstract Background: Vitamin D is very essential for health and its insufficiency is strongly associated with increased overall mortality. Health care workers (HCWs) need to educate on its uses and possible sources although studies show that their knowledge, attitude and practice is low; few studies are available in Ethiopia. The main aim of this study is therefore to assess the knowledge, attitude and practice of measuring adult vitamin D status, diagnosis of deficiency and managing health consequences among HCWs in Ethiopia. Methods: This study was conducted in three districts covering lowland, midland and highland ecologies. A total of 405 health extension workers, nurses, health officers, general practitioners and specialists were interviewed. Tablets were used for data collection to archive in a cloud server. Data were exported to Stata version 14 software for cleaning and analysis. Rates were computed and Chi-square test was used to compare differences between the two groups. Binary logistic regression was used to measure the strength, direction and significance of association between different covariates and the practice of HCWs.Result: The level of good knowledge, positive attitude and good practice in measuring adult vitamin D status, diagnosis of deficiency and managing health consequences among HCWs was 210(51.8%), 261(63.5%) and 195(47.4%) respectively. The odds of good practice in the provision of adult vitamin D service were AOR=6.87: 95% CI (3.57, 13.21) and AOR= 2.20: 95% CI (1.23, 3.92) times higher among HCWs in Addis Ababa and highlands compared with those working in lowlands. Good practice among clinicians was AOR=4.26: 95% CI (1.48, 12.25) times higher compared with those working in leadership positions. The likelihood was AOR=1.96: 95% CI (1.19, 3.23) times higher among those with good knowledge compared with those with poor knowledge. Besides, good practice in adult vitamin D service provision was AOR=2.30: 95% CI (1.40, 3.78) times higher among those with positive attitude compared with those who had negative attitude.Conclusions: Only a little over half of HCWs have good knowledge and close to two-third of them has positive attitude while less than half of them have good practice of measuring adult vitamin D status, diagnosis and managing its health consequences practice. Besides, HCWs residential ecology, clinical position, good knowledge and positive associated is associated with good practice on adult vitamin D. It is essential to provide rigorous and continues training for HCWs focusing on their deployment ecology.

Abstract. Background: Vitamin D deficiency (VDD) is a major public health problem. There are few comprehensive systematic reviews about the relationship between Vitamin D status and liver and renal disease in Iran. Methods: We systemically searched the following databases: Web of Science; PubMed; Cochrane Library; Scopus; Science Direct; Google Scholar and two Iranian databases (Scientific Information Database (SID) and IranMedex) up until November 2017 to identify all randomized control trials (RCTs), case control, cross-sectional and cohort studies investigating the association between vitamin D and any form of liver or kidney disease. Results: Vitamin D insufficiency, or deficiency (VDD), is highly prevalent in Iran, reports varying between 44.4% in Isfahan to 98% in Gorgan. There is also a high prevalence of VDD among patients with liver or kidney disease, and the administration of vitamin D supplements may have beneficial effects on lipid profile, blood glucose, liver function and fatty liver disease, and bone health. Low serum vitamin D levels are related with abnormalities in these laboratory and clinical parameters. Conclusion: VDD is prevalent in patients with chronic liver or renal disease in Iran. There appear to be several beneficial effects of vitamin D supplementation in vitamin D deficient patients with liver or kidney disease.

Abstract. Background: Hypovitaminosis D is a vitamin deficiency that has been increasing in developed countries; it was also suggested as an emerging risk factor for developing of atherosclerosis and acute myocardial infarction. The primary source of vitamin D is its cutaneous synthesis under exposure to sunlight. It has been suggested that 30 min of sun exposure twice weekly leads to sufficient vitamin D synthesis. The residents of Trieste (Italy) are well-known for their high exposure to sunlight in all seasons. We aimed to investigate the vitamin D status in subjects with acute myocardial infarction living in this area. Methods: Vitamin D status was identified in 478 subjects diagnosed with acute myocardial infarction. Results: The median serum 25-hydroxyvitamin D concentration was 14.5 [7.8 - 22.7] ng/mL. Vitamin D deficiency and insufficiency were present in 324 (68 %) and 107 (22 %) subjects, respectively. Vitamin D deficiency was less frequent among subjects enrolled in the period from July to the end of September (p < 0.001). In a multivariate analysis vitamin D deficiency was predicted by older age (p = 0.02), female gender (p = 0.002), higher body mass index (p = 0.05), autumn/winter sampling (p < 0.001), increased parathyroid hormone (p = 0.03) and alkaline phosphatase (p = 0.003). Conclusions: We observed very high prevalence of vitamin D deficiency among subjects with myocardial infarction in all seasons of enrollment. However, it was lower in the summer when sun exposure is higher. The exposure to sunlight may be a cost-saving therapeutic strategy for the management of vitamin D deficiency.

This review summarizes studies discussing vitamin D status in adults and reveals that vitamin D deficiency/insufficiency is highly prevalent in adults and that current fortification and supplementation policies are inadequate. Background and aims: Studies suggest a crucial role for adequate vitamin D status in various health conditions including bone metabolism, cancer, cardiovascular diseases, and allergies. However, relatively little is known about poor vitamin D status and unmet needs in adults. This report aims to highlight the contribution of epidemiologic studies (through the identification of health effects and societal burden) to the development of vitamin D fortification and supplementation policies and reveal unmet global challenges in adults. Methods: In order to assess worldwide vitamin D status in adults, the search strategy combined the medical literature database MEDLINE (using PubMed) for the time period between January 1, 1980 and February 28, 2011, using the key words vitamin D deficiency and insufficiency, and included articles in which access to full text was possible and in which healthy adults were assessed according to one of four commonly used vitamin D threshold classifications. Results: This report reveals that vitamin D deficiency occurs in 4.10 % [95 % CI (confidence interval), 3.93 %, 4.27 %] to 55.05 % (54.07 %, 56.03 %) of adults, while insufficiency occurs in 26.07 % (24.82 %, 27.33 %) to 78.50 % (77.85 %, 79.16 %), depending on the classification used. However, lack of overlap in CIs and high value of I2 statistics indicate considerable heterogeneity between studies. Further, certain populations (i. e. dark-skinned individuals, immigrants, and pregnant women) may be at higher risk for poor vitamin D status. Conclusion: Current policies for vitamin D supplementation and fortification are inadequate and new guidelines are required to improve vitamin D status in adults.
