Association of Smoking Initiation and Cessation Across the Life Course and Cancer Mortality: Prospective Study of 410 000 US Adults
Menée aux Etats-Unis à partir de données portant sur 410 000 adultes, cette étude prospective analyse l'association entre l'âge au début du tabagisme et lors de la cessation et la mortalité par cancer
Smoking remains the leading cause of cancer mortality in the US. Prior research has shown that smokers who start younger have greater mortality risk than those who start later, and quitting (especially at younger ages) substantially reduces that risk. However, the relevance of age at smoking initiation and cessation to cancer mortality in contemporary populations, particularly across the life course, is not well established.
