|Study Start Date:||June 2009|
|Study Completion Date:||October 2009|
|Primary Completion Date:||October 2009 (Final data collection date for primary outcome measure)|
Experimental: Vitamin D
Intervention arm: Oral vitamin D 100,000 IU once a month for three consecutive months.
Drug: Oral vitamin D 100,000 IU
Oral vitamin D 100,000 IU once a month for three consecutive months.
|Placebo Comparator: Placebo||
similar placebo once a month for three consecutive months
Eligible women will be invited by their primary care physician to participate in the study. After signing an informed consent women will be randomized to receive oral vitamin D 100,000 IU or similar placebo once a month for three consecutive months. Pertinent clinical and demographic date will be documented and relevant laboratory test will be performed by the primary care team. One month after the third dose the same data and tests will be retrieved on each woman. Compliance with the study protocol will be enhanced and confirmed by a research assistant.
To assess the relationship between IFG and 25(OH) vitamin D levels in overweight Arab women.
To assess whether vitamin D supplementation significantly improves IFG. To assess whether vitamin D supplementation significantly modifies IL-10 and hs-CRP.
