Ethnic differences in the effect of asthma on pulmonary function in children.

ABSTRACT:

Rationale

The impact of asthma on chronic lung function deficits is well known. However, there has been little study of ethnic differences in these asthma-associated deficits.

Objectives

To examine whether there are ethnic differences in the effects of asthma on children's lung function.

Methods
