Vitamin D Levels

Vitamin D deficiency/insufficiency has been primarily associated with skeletal disorders, however, since vitamin D receptors are found on multiple types of cells, there is also a link to increased chronic disease risk and all-cause mortality. The aim of this study was to examine whether deficient/insufficient vitamin D levels are associated with risk factors of chronic diseases and cognitive dysfunction in 50 to 70 year old adults. Participants completed the health status, three-day dietary record and vitamin D food frequency, sun exposure, and international physical activity questionnaires. Cognitive function of the participants was assessed using the Automated Neuropsychological Assessment Metrics while body composition (percent body fat, android/gynoid ratio) was assessed using Dual Energy X-ray Absorptiometry. Applanation tonometry was used to obtain pressure wave forms at the radial artery to examine arterial stiffness and central pressures. A fasting blood draw was taken to measure vitamin D, blood lipid and glucose levels. Fifty percent of the participants (36/72) were vitamin D deficient/insufficient. Individuals in the low physical activity (PA) group had lower serum vitamin D concentration compared to those in the high PA group (p = 0.04). Moreover, serum vitamin D levels were negatively related to risk factors of chronic diseases; blood glucose (r = −0.38; p = 0.01), triglycerides (r = −0.27; p = 0.02), and android/gynoid ratio (r = −0.32; p = 0.01). Deficient/insufficient vitamin D levels are linked to the risk factors of chronic diseases in men and women aged 50 to 70 years.

AbstractObjectiveWe quantified the prevalence of vitamin D status in 6–24-month-old underweight and normal-weight children and identified the socio-economic and dietary predictors for status.DesignCross-sectional, baseline data from a nutritional intervention study were analysed. Multinomial logistic regression was used to estimate the odds of being vitamin D deficient or insufficient with the reference being vitamin D sufficient.SettingUrban slum area of Mirpur field site, Dhaka, Bangladesh.SubjectsUnderweight (weight-for-age Z-score <−2·00) and normal-weight (weight-for-age Z-score ≥−1·00) children aged 6–24 months.ResultsAmong 468 underweight children, 23·1 % were sufficient, 42·3 % insufficient, 31·2 % deficient and 3·4 % severely vitamin D deficient. Among 445 normal-weight children, 14·8 % were sufficient, 39·6 % insufficient and 40·0 % deficient and 5·6 % severely deficient. With adjusted multinominal regression analysis, risk factors (OR (95 % CI)) for vitamin D deficiency in underweight children were: older age group (18–24 months old; 2·9 (1·5–5·7)); measurement of vitamin D status during winter (3·0 (1·4–6·4)) and spring (6·9 (3·0–16·1)); and maternal education (≥6 years of institutional education; 2·2 (1·0–4·9)). In normal-weight children, older age group (3·6 (1·2–10·6)) and living in the richest quintile (3·7 (1·1–12·5)) were found to be significantly associated with vitamin D insufficiency.ConclusionsThe study demonstrates a significant burden of vitamin D insufficiency and deficiency in both underweight and normal-weight children <2 years of age from an urban slum of Bangladesh. Identification of risk factors may help in mitigating the important burden in such children.

Sufficient Evidence

If environmental exposures are shown to cause an adverse health outcome, reducing exposure should reduce the disease risk. Links between exposures and outcomes are typically based on ‘associations’ derived from observational studies, and causality may not be clear. Randomized controlled trials to ‘prove’ causality are often not feasible or ethical. Here the history of evidence that tobacco smoking causes lung cancer—from observational studies—is compared to that of low sun exposure and/or low vitamin D status as causal risk factors for the autoimmune disease, multiple sclerosis (MS). Evidence derives from in vitro and animal studies, as well as ecological, case-control and cohort studies, in order of increasing strength. For smoking and lung cancer, the associations are strong, consistent, and biologically plausible—the evidence is coherent or ‘in harmony’. For low sun exposure/vitamin D as risk factors for MS, the evidence is weaker, with smaller effect sizes, but coherent across a range of sources of evidence, and biologically plausible. The association is less direct—smoking is directly toxic and carcinogenic to the lung, but sun exposure/vitamin D modulate the immune system, which in turn may reduce the risk of immune attack on self-proteins in the central nervous system. Opinion about whether there is sufficient evidence to conclude that low sun exposure/vitamin D increase the risk of multiple sclerosis, is divided. General public health advice to receive sufficient sun exposure to avoid vitamin D deficiency (<50 nmol/L) should also ensure any benefits for multiple sclerosis, but must be tempered against the risk of skin cancers.

Background: Vitamin D deficiency is one of the most common micronutrient deficiency in children worldwide, even in Bangladesh. However, to date, the prevalence of vitamin D deficiency among children of different region of Bangladesh is less reported. Objective: This study was conducted to assess vitamin D status of urban and rural Bangladeshi children including the risk factors associated with vitamin D deficiency are also evaluated. Methods: A multi-centre (urban and rural based), cross sectional study was done from July 2016 to June 2017, using serum 25(OH) vitamin D3 as a marker of nutritional vitamin D status. Urban and rural children were taken from Paediatric Outpatient Department, United Hospital Limited. Dhaka and Medical Outpatient Department, Upazila Health Complex, Ghatail, Tangail respectively. Children of 1-10 years age attending OPD with mild undernutrition (<–1 SD z score) and/or clinical features suggestive of vitamin D deficiency were included in the study. Results: A total 150 children were studied with 102 (68.0%) urban and 48 (32.0%) rural children. Hypovitaminosis D (25-OHD <30ng/ml) was found in 75.0% of children. Hypovitaminosis D was found significantly more in urban children (81.0%) compared to rural (62.0%) children (OR=0.382, 95% CI: 0.177-0.822, p value <0.05). Inadequate exposure to sunlight was significantly associated with hypovitaminosis D compared to adequate sun exposure and it was about 2.5 times higher (OR=2.475, 95% CI: 1.139-5.380, p value <0.05). No significant associations of vitamin D deficiency were detected with skin color of children, covering clothes of mother, exclusive breast feeding, limb pain and anthropometric status. Children of higher educated mother (above Secondary School Certificate) (OR=0.412, 95% CI: 0.189-0.900) were more associated with vitamin D deficiency. Conclusion: Vitamin D deficiency (VDD) is prevalent among Bangladeshi children, urban children being more vulnerable to VDD. Adoption of a screening programme for children of all age group and implementation of preventive strategies for VDD through public health policies are strongly recommended.
