Second-hand smoke exposure is highest in eastern Asia and Oceania and higher among women and children compared with men. The distribution of DALYs attributable to second-hand smoke exposure is bimodal, with peaks in the post-neonatal period and again in older age groups. Globally 0·9 million (0·7 million to 1·1 million) deaths were attributable to second-hand smoke exposure, of which 56 340 (28 951–89 043) occurred among children younger than age 10 years.
