Association of Symptoms of Obstructive Lung Disease and All-Cause Mortality in Older Adult Smokers.

ABSTRACT: OBJECTIVES:This study aims to investigate the impact of respiratory symptoms in current and former smokers with and without obstructive lung disease (OLD) on all-cause mortality. DESIGN:Secondary analysis in a prospective cohort (the Health, Aging and Body Composition study). SETTING:Memphis, Tennessee, and Pittsburgh, Pennsylvania. PARTICIPANTS:Black and white men and women with a history of current and former smoking (N = 596; 63% male and 37% female) aged 70-79 years followed for 13 years. Participants were categorized into 4 mutually exclusive groups based on symptom profile and forced expiratory volume in the 1st second to forced vital capacity ratio. The groups were Less Dyspnea-No OLD (N = 196), More Dyspnea-No OLD (N = 104), Less Dyspnea-With OLD (N = 162), and More Dyspnea-With OL
