Women who participated in exercise as adolescents had a reduced risk of death from cancer and all causes in their middle and older ages. After adjusting for socioeconomic factors in adult life, the researchers found that women who participated in exercise as adolescents for 1.33 hours a week or less had a 16 percent lowered risk for death from cancer, and a 15 percent lowered risk for death from all causes; those who participated in exercise as adolescents for more than 1.33 hours a week had a 13 percent lowered risk for death from all causes.
