Abstract

A total of 344 employees at Notre Dame University, Lebanon completed three questionnaires: food frequency questionnaire, background questionnaire (socio-demographic & lifestyle factors), and international physical activity questionnaire — short form. Serum 25(OH)D level was measured using the Calbiotech 25(OHD) enzyme-linked immunosorbent assay Kit (Spring Valley, California, USA). Vitamin D status was determined based on the National Osteoporosis Foundation (suboptimal vs. optimal: serum 25(OH)D level < vs. ≥ 75 nmol/L /< vs. ≥30 ng/mL) and the Institute of Medicine (inadequacy or adequacy: 25(OH)D < or ≥50 nmol/L /< or ≥20 ng/mL) guidelines. The National Cholesterol Education Program Adult Treamten Panel III criteria  for the Metabolic Syndrome ( MetS) were used to identify individuals with MetS and any of its components. The data were analyzed using the SPSS version 22 for Windows. A p-value <0.05 was considered to be statistically significant. The prevalence rate of MetS was found to be 23.5%. Among MetS components, central obesity was the most prevalent condition (50.6%), followed by hypertriglyceridemia (32.6%), low HDL levels (23.8%), high blood pressure (21.2%) and last by impaired fasting blood glucose (20.3%). Using the National Osteoporosis Foundation and Institute of Medicine guidelines respectively, the odds of having MetS were found to be 2.5 to 3 times higher among those with suboptimal or inadequate vitamin D status than those with optimal or adequate vitamin D status, after adjustment for confounders. Study findings can be used to spread awareness about the potential role of optimal/adequate vitamin D status in preventing development of MetS
