Identification of the Region of Vitamin D Responsiveness (GRH-PN01)
Hypothesis: low vitamin D status is associated with increased insulin resistance and increased blood pressure.
Approach: Multiple regression analysis of information extracted from a large database accumulated by a Canadian health foundation, specifically evaluating statistical associations between serum 25(OH)D levels and insulin responsiveness measures as well as blood pressure, after adjusting these variables for BMI, age, sex, and waist circumference.
|Study Design:||Observational Model: Ecologic or Community
Time Perspective: Cross-Sectional
|Official Title:||A Novel Approach Localizes the Association of Vitamin D Status With Insulin Resistance to One Region of the 25(OH)D Continuum.|
