Bone density in axial and appendicular skeleton in patients with lactose intolerance: influence of calcium intake and vitamin D status.

Background: Lactose intolerance (LI) is a common enzymatic insufficiency, manifesting by poor tolerance of dairy products, leading to low calcium intake and poor calcium absorption from dairy products. These changes might lead to an impairment of bone metabolism [1].

Objectives: To evaluate the impact of LI on quantitative bone parameters in axial and appendicular skeletal sites.
