Prevalence, mortality and risk factors for self-reported COPD among smokers and never smokers, NHANES 1999-2018.

ABSTRACT:

Introduction

Cigarette smoke is the main risk factor for chronic obstructive pulmonary disease (COPD), but 25% to 50% of cases occur in non-smokers. In the US, limited recent national data compare COPD prevalence between smokers and never smokers. Furthermore, our study seeks to explore the prevalence and mortality of self-reported COPD among smokers (including current smokers and ex-smokers) and never smokers in the US from 1999 to 2018, and to identify the risk factors and differences.

Methods

This cross-sectional analysis used data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018. Age-standardized prevalence of self-reported COPD among current smokers, ex-smokers, and never smokers was calculated using sample weights and 2010 US Census estimate
