Leisure-time physical activity and leukocyte telomere length among older women.
BACKGROUND Shortened leukocyte telomere length (LTL), a purported marker of cellular aging, is associated with morbidity and mortality. However, the association of physical activity, a modifiable lifestyle behavior, with LTL has not been adequately studied among older adults. METHODS In this cross-sectional study, we examined associations of various intensity levels of leisure-time physical a...
متن کاملAssociation of Accelerometer-Measured Physical Activity With Leukocyte Telomere Length Among Older Women.
Background Previous studies on physical activity and telomere length have relied largely upon self-reported physical activity data, and few studies have examined older adults. The association of objectively measured physical activity with leukocyte telomere length (LTL) is currently unknown. Methods In this study, we examined cross-sectional associations between accelerometer-measured total, ...
متن کاملChildhood Physical and Sexual Abuse History and Leukocyte Telomere Length among Women in Middle Adulthood
OBJECTIVE Abuse victimization in childhood is associated with a variety of age-related cardiometabolic diseases, but the mechanisms remain unknown. Telomeres, which form the protective caps at the ends of chromosomes, have been proposed as measures of biological age, and a growing body of research suggests that telomere attrition may help to explain relationships between stress and cardiometabo...
متن کاملAssociations of Accelerometer-Measured and Self-Reported Sedentary Time With Leukocyte Telomere Length in Older Women.
Few studies have assessed the association of sedentary time with leukocyte telomere length (LTL). In a cross-sectional study conducted in 2012-2013, we examined associations of accelerometer-measured and self-reported sedentary time with LTL in a sample of 1,481 older white and African-American women from the Women's Health Initiative and determined whether associations varied by level of moder...
متن کاملDifferences in Exercise Performance and Leisure-time Physical Activity in Older Men and Women.
PURPOSES (a) To compare exercise performance and leisue-time physical activity (LTPA) between older men and women, (b) to assess the relationship between exercise performance and LTPA, and (c) to determine whether group differences in exercise performance persist after controlling for LTPA. METHODS A total of 105 women and 155 men who were 65 years of age and older participated in this study....
