Impact of smoking behaviors on asthma incidence and allcause mortality in middle-aged and older adults: A longitudinal study from China.

ABSTRACT:

Introduction

The impact of smoking behaviors on asthma incidence and all-cause mortality among middle-aged and older adults remains understudied. In particular, whether the potential effect of adolescent smoking initiation on late-onset asthma is independent of cumulative tobacco exposure is unclear.

Methods

Cox proportional hazards models assessed longitudinal impact of smoking behaviors on asthma incidence and mortality risks using 2011-2018 China Health and Retirement Longitudinal Study (CHARLS) data. Cross-sectional smoking-asthma associations were analyzed with logistic regression. Additionally, restricted cubic splines were used to assess the nonlinear relationships between smoking characteristics and asthma incidence.

Results

Smokers had a 65% higher risk of in
