Body size and physical activity in relation to incidence of chronic obstructive pulmonary disease.

ABSTRACT:

Background

Limited evidence suggests that adiposity and lack of physical activity may increase the risk of chronic obstructive pulmonary disease (COPD). We investigated the relation of body size and physical activity with incidence of COPD.

Methods

We obtained data on anthropometric measurements and physical activity from 113,279 participants in the National Institutes of Health-AARP Diet and Health Study who reported no diagnosis of COPD at baseline (1995-1996). We estimated associations between these measurements and subsequent diagnosis of COPD between 1996 and 2006, with extensive adjustment for smoking and other potentially confounding variables.

Results

Participants reported 3648 new COPD diagnoses during follow-up. The incidence of COPD was higher in both sever
