It is well known that smoking is an important cardiovascular and cerebrovascular risk factor. Now, some studies have proved that smoking is not only a major harm to cardiovascular and cerebrovascular health, but also a major cause of chronic obstructive pulmonary disease. Smoking is associated with accelerated decline in lung function, increased mortality, and worsening symptoms in asthma and COPD (Boulet et al., 2006). There are also meta-analyses that show smokers have an increased risk of fracture (Kanis et al., 2005; Shen et al., 2015). Vitamin D is one of the most important fat-soluble vitamins in the body, the most important of which are D2 and D3. As the main circulating form of vitamin D, 25(OH)D plays an important role in regulating cell proliferation and immune response, in addition to regulating serum calcium and phosphorus levels (Umar et al., 2018; Vanherwegen et al., 2017). Studies have found that inhibiting the production of cAMP protein induced by 1,25(OH) 2D3 can enhance

Serum vitamin D levels in relation to metabolic syndrome: A systematic review and dose–response meta‐analysis of epidemiologic studies

et al. 2021

Summary Several epidemiological studies examined the association of serum vitamin D with metabolic syndrome (MetS), but the findings were inconsistent. We conducted a systematic review and dose–response meta‐analysis to quantify the association between blood vitamin D levels and MetS in adults. A systematic search up to December 2020 was conducted in MEDLINE (PubMed), ISI (Web of Science), Scopus, and Google Scholar databases for epidemiological studies that assessed the relation of serum 25‐hydroxyvitamin D (as the exposure) and MetS (as the outcome) in adults. Eligible cross‐sectional studies were restricted to those with representative populations. Finally, 43 studies were included in the analysis (38 cross‐sectional, one nested case–control, and four cohorts studies). Combining 41 effect sizes from 38 cross‐sectional studies included 298,187 general adult population revealed that the highest level of serum vitamin D, compared with the lowest level, was significantly related to a 43% decreased odds of MetS in developed countries (odds ratio [OR]: 0.57; 95% confidence interval [CI]: 0.49–0.65) and 40% in developing countries (OR: 0.60; 95% CI: 0.52–0.70). Linear dose–response analysis (including 222,175 healthy individuals and 39,308 MetS patients) revealed that each 25 nmol/L increase in serum vitamin D level was significantly associated with a 15% decreased odds of MetS (OR: 0.85; 95% CI: 0.80–0.91); however, we found no significant nonlinear association. Meta‐analysis of five prospective studies with 11,019 participants revealed no significant relation (relative risk [RR]: 0.70; 95% CI: 0.37–1.32). This meta‐analysis indicated an inverse association between serum vitamin D concentrations and risk of MetS in general adult populations in cross‐sectional studies in a dose–response manner. However, no significant association was found in a small number of cohorts. More prospective studies are needed to confirm the causality of this relationship.

“…[18][19][20] Finally, although prior studies have shown a positive relationship between VDD and obesity biomarkers. [21][22][23] some of these biomarkers, including waist, hip, weight and body mass index (BMI), are still controversial in terms of the association degree with VDD particularly in relation to lifestyle stressors. Therefore, the purpose of this study was to assess the association between selected lifestyle stressors and the severity of VDD in healthy Jordanians.…”

Background: To identify stress associated factors for vitamin D deficiency (VDD) in healthy Jordanian people based on serum 25(OH)D levels. Design: Prospective cohort study. Methods: Three hundred and seventy-one Jordanian men and women aged 17-52 years, who were identified as VD deficient 25(OH)D <30 ng/mL, were eligible to participate in the study. Serum vitamin 25(OH) D was measured using chemiluminescent immunoassay. Cortisol, parathyroid hormone, calcium, phosphate, fasting lipid profile, and blood glucose were also analyzed. Questionnaires were used to collect lifestyles parameters. Anthropometric parameters including: body mass index (BMI), waist (W) and hip (H) circumferences, W/H ratio (WHR) were also calculated. Results: The vast majority (91%) of the participants had vitamin D deficiency (25-(OH) D <30 ng/mL). Positive correlations were observed between vitamin D deficiency and the following anthropometric parameters in all study sample; gender (P=0.010), height (P=0.22), height/hip ratio (P=0.015) and waist/hip ratio (P=0.013). Lifestyle parameters that indicated very weak positive correlations with VDD were number of family members (P=0.011) and insufficient exposure to sunlight (P=0.023). The following clinical parameters showed weak or very weak correlations with VDD; serum cortisol (r=0.318), low density lipoprotein (r=0.246) and total cholesterol (r=0.133). Skin color and water pipe tobacco smoking were added to the multivariable stepwise regression analyses as they have been weakly correlated with VDD. These predictors together explained only 12.2% of the variance in serum cortisol levels in the VDD study sample. Conclusion: A weak positive association between VDD and elevated serum cortisol was observed in this study. Subcutaneous changes may be involved in that association but further studies are needed to clarify a potential role for adrenocorticotropic hormone (ACTH).
