Qatar Biobank (QBB), the first very large scale, long-term public biorepository in Qatar, is designed to build a powerful research infrastructure for future investigations of the lifestyle, metabolic and genetic risk factors by collecting comprehensive phenotypic baseline data among healthy volunteers, As of March 2016, the Qatar Biobank has reached a cohort size of around 5230 men and women aged 18 years and older, the present study include a 3070 Qatari Nationals, 51% of them were men and 49% women. Mean age between men and women at enrollment did almost not differ 38.8 years for men and 39.6 years for women, were men were more physically active then women (p<0.0001). Our data on physical measurements showed that three quarter of both men and women was overweight or even obese. Women had a higher BMI (29.4 kg/m2 versus 28.6 kg/m2, p<0.0001. Approximately one-third of men (33.2%) and one-fifth of women (20.0%) had pre-hypertension (p<0.0001). Almost 10% of men and women had hypertension. Analyses of a selection of the blood data showed overall that men had a worse lipid profile than women had (p<0.0001). Approximately 8% of men and 11% of women had a severe Vitamin D deficiency, and even 84% of men and 77% of women were at risk with a mild to moderate Vitamin D deficiency. Almost 14% of all participants reported that they were diagnosed with diabetes. Nineteen percent of the participants with an HbA1c above 6.5% did not even know they had diabetes.
