Serum 25-hydroxy-vitamin D and ionised calcium in relation to lung function and allergen skin tests.

ABSTRACT:

Background

Evidence suggests that higher levels of vitamin D and calcium are associated with greater lung function and that vitamin D is inversely associated with atopic sensitisation. It is unknown whether the associations of vitamin D and calcium with lung function are independent of each other or mediated by atopic sensitisation.

Objective

To study the associations of 25-hydroxyvitamin D (25(OH)D) and ionised calcium levels with lung function and specific allergen sensitisation in adolescents (12-19 years) and adults (20-59 years) and to assess whether the associations with lung function are due to altered atopic sensitisation.

Methods

This is a cross-sectional analysis of the data from the third National Health and Nutrition Examination Survey.
