en عمومى General پژوهشي Research <p dir="ltr"><strong>Background- </strong>Recent studies have reported the high prevalence of different degrees of vitamin D deficiency in Iran. The present study was conducted to determine the correlation between serum levels of vitamin D and Peak Bone Mass (PBM) in a group of Iranian population at the age of PBM.</p> <p dir="ltr"><strong>Material & Methods-</strong> The present cross-sectional study was conducted on 20-35 year-old adults participating in the first phase of the Iranian Multicentric Osteoporosis Study (IMOS). The correlation between serum levels of 25(OH)D and BMD values were assessed by Spearman correlation coefficient.</p> <p dir="ltr"><strong>Results-</strong>1941 individuals were studied. There was no significant difference between BMD&nbsp; values at the studied areas with vitamin D levels nor status groups in either gender.</p> <p dir="ltr"><strong>Conclusion-</strong> Our study revealed no association between serum vitamin D levels and BMD in individuals at the age of PBM.</p> Vitamin D, Osteoporosis, Peak Bone Mass, Bone Mineral Density 401 406 http://intjmi.com/browse.php?a_code=A-10-1-128&slc_lang=en&sid=1 Nahid Eshagh Hosseini 10031947532846002595 10031947532846002595 No Osteoporosis Research Center, Endocrinology and Metabolism Clinical Sciences Institute, Tehran University of Medical Sciences, Tehran, Iran, Hamidreza Aghaei Meybodi 10031947532846002596 10031947532846002596 Yes Osteoporosis Research Center, Endocrinology and Metabolism Clinical Sciences Institute, Tehran University of Medical Sciences, Tehran, Iran, Abbasali Keshtkar 10031947532846002597 10031947532846002597 No Department of Health Sciences Education Development, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran, Mohsen Rezaei Homami 10031947532846002598 10031947532846002598 No Institute of Health & Wellbeing, Health Economics & Health Technology Assessment, University of Glasgow, Glasgow, UK Patricia Khashayar 10031947532846002599 10031947532846002599 No Center for Microsystems Technology, Imec and Ghent University, Gent-Zwijnaarde, Belgium, Bagher Larijani 10031947532846002600 10031947532846002600 No Endocrinology and Metabolism Research Center, Endocrinology and Metabolism Clinical Sciences Institute, Tehran University of Medical Sciences, Tehran, Iran
