Key result
Regular passive smoking linked to ~91% higher CHD risk in nonsmoking women.
Why the study?
Previous epidemiological studies suggested an association of passive smoking with CHD but lacked assessment of workplace exposure and control for all confounders.
Does exposure to passive smoking increase the risk of incident CHD in nonsmoking women?
Cohort (n=32,046)
Does exposure to passive smoking increase the risk of incident CHD in nonsmoking women?
Relative Risk: 1.91 (95% CI 1.11–3.28)
Regular exposure to passive smoking at home or work significantly increases the risk of incident coronary heart disease among nonsmoking women.

May support avoiding passive smoke to lower CHD risk in nonsmoking women; extends prior observational data but leaves causality open.
Kawachi et al. (1997) conducted a cohort in Coronary heart disease (n=32,046). Passive smoking vs. No exposure to passive smoking was evaluated on Incident coronary heart disease (RR 1.91, 95% CI 1.11-3.28). Regular exposure to passive smoking at home or work increased the risk of incident coronary heart disease among nonsmoking women (RR 1.91; 95% CI 1.11-3.28).
