Implication

Prospective cohort study finds no significant link between spousal secondhand smoke and mortality in never smokers, suggesting weaker associations than previously believed.

Key Points

To measure the association between environmental tobacco smoke exposure from spousal smoking and long-term mortality from coronary heart disease, lung cancer, and chronic obstructive pulmonary disease.
Prospective cohort study tracking 118,094 California adults enrolled in late 1959 in the American Cancer Society cancer prevention study (CPS I) across 39 years until 1998.
Evaluated 35,561 never smokers (9,619 men and 25,942 women) whose spouses had documented smoking histories.
In never-smoking men married to ever smokers versus never smokers, the age-adjusted relative risk was 0.94 (95% CI, 0.85 to 1.05) for coronary heart disease, 0.75 (95% CI, 0.42 to 1.35) for lung cancer, and 1.27 (95% CI, 0.78 to 2.08) for chronic obstructive pulmonary disease.
In never-smoking women married to ever smokers versus never smokers, the age-adjusted relative risk was 1.01 (95% CI, 0.94 to 1.08) for coronary heart disease, 0.99 (95% CI, 0.72 to 1.37) for lung cancer, and 1.13 (95% CI, 0.80 to 1.58) for chronic obstructive pulmonary disease.
No statistically significant associations were identified across four shorter follow-up intervals or after controlling for seven confounding variables and excluding individuals with pre-existing disease.
