Scientific research over the last decade has increasingly demonstrated that exposure to secondhand smoke is not simply a nuisance; it is deadly. Secondhand smoke exposure causes multiple diseases in children, including asthma and pneumonia, and results in thousands of avoidable hospitalizations. Secondhand smoke exposure is a major cause of sudden infant death syndrome and may cause lung cancer and heart attacks with repeated exposure. No safe level of exposure exists.

Metabolic, hormonal, and hemostatic changes associated with pregnancy loss (stillbirth and miscarriage) may contribute to the development of cardiovascular disease (CVD) in adulthood. This study evaluated prospectively the association between a history of pregnancy loss and CVD in a cohort of postmenopausal women.
