Sedentary behavior, physical activity and cardiorespiratory fitness on leukocyte telomere length
Background: Emerging work is starting to investigate the cumulative effects of moderate-to-vigorous physical activity (MVPA), sedentary behavior and cardiorespiratory fitness on health. The objective of this study was to examine the cumulative and independent associations of MVPA, sedentary behavior and cardiorespiratory fitness on leukocyte telomere length (LTL). Methods: Data from the 1999-20...
متن کاملLeisure-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 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 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 کاملPhysical Activity, Physical Fitness, and Leukocyte Telomere Length: The Cardiovascular Health Study.
INTRODUCTION The influence of physical activity (PA) and physical fitness (PF) at older ages on changes in telomere length (TL)--repetitive DNA sequences that may mark biologic aging--is not well-established. Few prior studies (mainly cross-sectional) have been conducted in older adults, and few studies have evaluated PF. METHODS We investigated cross-sectional and prospective associations of...
