Background: The prevalence of obesity and vitamin D deficiency in Saudi Arabia has increased recently. Decreased physical activity might play a role in obesity. Previous studies showed an association between low vitamin D level and its receptor polymorphism with obesity development.
Objective: To determine association of low vitamin D level and its receptor polymorphism with obesity in Saudi men.
Methods: This case control study was carried out from March 2016 through March 2017. Three hundred Saudi male students (from applied medical sciences in Taif University, Taif, Saudi Arabia) were classified according to BMI into lean, overweight and obese groups. For each individual, blood glucose, cholesterol, HDL-C, LDL-C, insulin and 25-(OH) vitamin D were measured. In addition, Apal, BsmI and TaqI genotypes were performed for each individual from March 2016 through March 2017, through computer-based search of the following databases: PubMed, Web of Science (Thomson ReutersTM). The references of the original literature and the related articles were also searched, for potential complementary studies. Data were analyzed by SPSS version 16, using Spearman's rho and ANOVA tests.
Results: There was significant negative association between 25-(OH) vitamin D level and obesity (p<0.01). Genotyping study showed that both bb of BsmI and tt of TaqI genotypes were higher in the obese group compared with lean group (p<0.05). Moreover, bb genotype has higher BMI and HOMA-IR than both BB and Bb; and tt genotype also has higher BMI and HOMA-IR than TT and Tt genotypes (p<0.05).
Conclusion: Low vitamin D level and VDR BsmI and Taq1 genotypes may be a risk factor of obesity.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.
The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research.
