Respiratory Health and Cigar and Pipe Use in the NHLBI Pooled Cohorts Study

Principal Investigator: Elizabeth Oelsner

Funding Mechanism: National Institutes of Health - Grant

ID number: 1R21HL153700-01

Award Date: 7/27/2020

Institution: Columbia University Health Sciences

Cigarette smoking is the major risk factor for chronic lower respiratory disease (CLRD), which includes chronic obstructive pulmonary disease (COPD) and asthma. The goal of this study is to test whether cigar and pipe use is associated with accelerated lung function decline and CLRD-related hospitalizations and mortality. Researchers will analyze data from the National Heart, Lung, and Blood Institute (NHLBI) Pooled Cohorts Study, which collected lung function data (including spirometry exam data) from nine US general population-based cohorts that included 65,251 American Indian, Asian, Black, Hispanic and White adult men and women. Study aims are: (1) to harmonize self-reported interview questions on cigar and pipe use across the study cohorts in order to characterize cigar/pipe use; (2) to assess associations between cigar/pipe use and lung function changes over time, including rates of forced expiratory volume in one second (FEV1) decline, forced vital capacity (FVC) decline, FEV1/FVC, and airflow obstruction; and (3) to assess the association between cigar/pipe use and CLRD-related hospitalizations and mortality. Study findings may inform future regulatory activities related to cigar and pipe tobacco products.
