New research suggests that teens who exercise during their teen years have a reduced risk of death in their middle and older ages, Reuters reported.
Researchers found that women who participated in exercise as adolescents had a reduced risk of death from cancer and all causes in their middle and older ages.
"In women, adolescent exercise participation, regardless of adult exercise, was associated with reduced risk of cancer and all-cause mortality," researcher Sarah Nechuta said in a statement. "Our results support the importance of promoting exercise participation in adolescence to reduce mortality in later life and highlight the critical need for the initiation of disease prevention early in life."
For the study, researchers analyzed data from the Shanghai Women's Health Study which involved about 75,000 women between the ages of 40 and 70 years. After an average of 12.9 years of follow-up, there were 5,282 deaths, including 2,375 from cancer and 1,620 from cardiovascular disease, Live Science reported.
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.
They also found that women who participated in team sports as adolescents had a 14 percent lowered risk for death from cancer, and a 10 percent lowered risk for death from all causes. Women who participated in exercise both in their adolescent and adult lives had a 20 percent lowered risk for death from all causes.
"While we found adolescent exercise to be associated with lowered risk of death from cancer and cardiovascular disease as adults, some associations were attenuated after adjusting for adult factors that may influence mortality later in life, such as exercise, diet, body mass index [BMI], socioeconomic status, and a history of chronic diseases. However, it is important to note that adult factors, such as adult exercise, BMI, and chronic diseases are potentially influenced by adolescent exercise, and adjusting for adult factors in these types of studies may not always be the best approach, as overadjustment could be a concern," Nechuta added.
Nechuta said further studies with more detailed adolescent physical activity assessments and studies in other populations are needed.
