Vitamin D levels and deficiency with different occupations: a systematic review

BackgroundVitamin D deficiency is prevalent worldwide, but some groups are at greater risk. We aim to evaluate vitamin D levels in different occupations and identify groups vulnerable to vitamin D deficiency.MethodsAn electronic search conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, and CINAHL Plus with Full Text generated 2505 hits; 71 peer-reviewed articles fulfilled the inclusion criteria. Occupations investigated included outdoor and indoor workers, shiftworkers, lead/smelter workers, coalminers, and healthcare professionals. We calculated the pooled average metabolite level as mean ± SD; deficiency/insufficiency status was described as % of the total number of subjects in a given category.ResultsCompared to outdoor workers, indoor workers had lower 25-hydroxyvitamin D (25-(OH)D) levels (40.6 ± 13.3 vs. 66.7 ± 16.7 nmol/L; p < 0.0001). Mean 25-(OH)D levels (in nmol/L) in shiftworkers, lead/smelter workers and coalminers were 33.8 ± 10.0, 77.8 ± 5.4 and 56.6 ± 28.4, respectively. Vitamin D deficiency (25-(OH)D < 50 nmol/L), was high in shiftworkers (80%) and indoor workers (78%) compared to outdoor workers (48%). Among healthcare professionals, medical residents and healthcare students had the lowest levels of mean 25-(OH)D, 44.0 ± 8.3 nmol/L and 45.2 ± 5.5 nmol/L, respectively. The mean 25-(OH)D level of practising physicians, 55.0 ± 5.8 nmol/L, was significantly different from both medical residents (p < 0.0001) and healthcare students (p < 0.0001). Nurses and other healthcare employees had 25-(OH)D levels of 63.4 ± 4.2 nmol/L and 63.0 ± 11.0 nmol/L, respectively, which differed significantly compared to practising physicians (p = 0.01), medical residents (p < 0.0001) and healthcare students (p < 0.0001).Rates of vitamin D deficiency among healthcare professionals were: healthcare students 72%, medical residents 65%, practising physicians 46%, other healthcare employees 44%, and nurses 43%. Combined rates of vitamin D deficiency or insufficiency (25-(OH)D < 75 nmol/L) were very high in all investigated groups.Potential confounders such as gender and body composition were not consistently reported in the primary studies and were therefore not analyzed. Furthermore, the descriptions of occupational characteristics may be incomplete. These are limitations of our systematic review.ConclusionsOur review demonstrates that shiftworkers, healthcare workers and indoor workers are at high risk to develop vitamin D deficiency, which may reflect key lifestyle differences (e.g. sunlight exposure). This may help target health promotion and preventive efforts.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4436-z) contains supplementary material, which is available to authorized users.

Background:The prevalence of vitamin D deficiency has recently been recognized in different parts of the world, even affecting healthy populations. The deficiency of vitamin D can lead to rickets in children and osteomalacia in adults. Few studies have been done to evaluate the status of vitamin D in the medical community. The objective of this study was to evaluate the prevalence of low levels of vitamin D in healthy Saudi medical students.Materials and Methods:A cross-sectional study was carried out in November 2009 on male and female students in the preclerkship years of medical school at the King Faisal University, Dammam. Data on age, consumption of dairy products and seafood, and exposure to sunlight were collected. The body mass index was calculated. Approximately, 15 ml of blood was extracted for the measurement of serum calcium, serum albumin, serum phosphorus, alkaline phosphatase, fasting parathyroid hormone, and vitamin D levels. Vitamin D deficiency was defined as serum 25-hydroxy vitamin D < 50 nmol/l. Comparison between groups was done for statistical significance using an unpaired t-test. Significance was set at P < 0.05 using 95% CI for all comparisons.Results:The data from 95 male and 103 female students were analyzed. The mean age for all students was 19.54 years. In 100% of the students, the vitamin D level was low. The prevalence of vitamin D deficiency in all students was 96.0% (92.64% in males and 99.03% in females), while the remaining 4% had vitamin D insufficiency. The mean 25-hydroxy vitamin D level was 26.83 ± 12.60 nmol/l in males and 16.03 ± 8.28 nmol/l in females (P-value = 0.0001). Males had a statistically significant higher body mass index as well as consumption of dairy products, while the consumption of seafood was significantly higher in females. There was no difference between the two groups in terms of exposure to the sun.Conclusion:Vitamin D deficiency was highly prevalent among medical students included in this study. An urgent action has to be taken in order to prevent adverse consequences of low vitamin D in the young, otherwise healthy populations.

“…A factor which could have had an influenced on this is a lower production of vitamin D at this time of year. In spite of the fact that Gran Canaria enjoys adequate and consistent levels of sunshine throughout the year, in studies carried out by our working group in medical students in Gran Canaria, it was observed that 61.2% of them had values of 25(OH) vitamin D below 30 ng/ml 18 we are not able to determine 19 . Although to clarify this fact, it would be necessary to understand the circumstances in which hip fractures occurred.…”

Background: Hip fracture is the most serious clinical complication of osteoporosis, due to its raised morbidity and mortality. Method: We have studied the epidemiological and demographic characteristics of all the fragility fractures of the hip occurring in patients of ≥ 50 years of age recorded in Gran Canaria during the 5 year period of 2007-2011 from the admission, coding, emergency and traumatology services of all the hospitals in Gran Canaria, in both the public and private healthcare sectors. Results: A total of 2,222 hip fractures were recorded, of which 1,593 (71.7%) occurred in women and 629 (28.3%) in men. The female/male ratio was 2.53. The average age at which the fractures occurred was 79 ± 9.7 years. Over the 5 years, the total number of fractures (men and women) varied between 402 (in 2007) and 504 (in 2010). The number of fractures increased with age up to the 90s. The annual global incidence was 150 cases/100,000 inhabitants ≥ 50 years: in women 205.4 cases with respect to the population of this sex and age, and in men, 89.1 with respect to the population of men ≥ 50 years. During the winter months 29.7% of the total fractures occurred, 7.5% more than those happening during the summer months (22.2%). Conclusions: During the period 2007-2011 the incidence of hip fracture in Gran Canaria remained more or less stable, in every year being greater in women than in men, and increasing with age up until the 90s. The greatest number of hip fractures occurred during the winter months, with similar numbers in spring, summer or autumn.
