Secondhand smoke (SHS) exposure significantly worsens lung function and increases cardiovascular mortality risk in older adults. This study highlights the long-term health consequences of SHS, emphasizing the need for protective measures.

Area of Science:

  • Environmental Health
  • Cardiovascular Medicine
  • Pulmonology

Background:

  • Cardiovascular disease and obstructive lung disease are leading global causes of mortality.
  • The precise impact of secondhand smoke (SHS) exposure on pulmonary function and cardiovascular health remains incompletely understood.
  • Investigating SHS exposure's long-term effects is crucial for public health strategies.

Purpose of the Study:

  • To determine the association between baseline SHS exposure and the risk of lung function decline over nearly a decade.
  • To elucidate the relationship between SHS exposure and cardiovascular mortality.
  • To explore potential mediating roles of lung function (FEV1) and baseline cardiovascular disease status.

Main Methods:

  • Longitudinal cohort study of 1,057 older adults.

  • Analysis of baseline SHS exposure (home and work) and its association with lung function decline (FEV1) and cardiovascular mortality.
  • Utilized marginal structural models (MSMs) to account for mediating effects of FEV1 and baseline cardiovascular disease.

    • Main Results:

    • Lifetime cumulative SHS exposure was linked to a greater decline in FEV1.
    • Lifetime home SHS exposure showed an increased risk of cardiovascular mortality.
    • The association between SHS and cardiovascular mortality persisted even after accounting for FEV1 and baseline cardiovascular disease.

    Conclusions:

    • Lifetime SHS exposure is associated with accelerated lung function decline.
    • SHS exposure increases the risk of cardiovascular mortality.
    • Findings underscore the detrimental effects of SHS on both pulmonary and cardiovascular health.
