Article Abstract
Purpose: To investigate the associations among objectively measured sedentary behavior, light physical activity, and markers of cardiometabolic health in young women.
Methods: Cardiovascular disease risk factors, homeostasis model assessment for insulin resistance (HOMA-IR), lipid accumulation product, and inflammatory markers were measured in 50 young, adult women. Accelerometers were worn over 7 days to assess sedentary time (<150 counts min(-1)), light physical activity (150-2,689 counts min(-1)), and moderate-to-vigorous physical activity (MVPA; ≥2,690 counts min(-1)). Multivariate regression examined independent associations of sedentary behavior and light physical activity with cardiometabolic health. Covariates included MVPA, cardiorespiratory fitness (VO2peak) and body mass, and body composition.
Results: Sedentary behavior was associated with triglycerides (p = 0.03) and lipid accumulation product (p = 0.02) independent of MVPA. These associations were attenuated by VO2peak and body mass or body composition (p ≥ 0.05). Light physical activity was independently associated with triglycerides and lipid accumulation product after adjustment for all covariates (p < 0.05). The association between light physical activity and HOMA-IR was independent of MVPA (p = 0.02) but was attenuated by VO2peak and body mass or body composition (p > 0.05).
Conclusions: Sedentary behavior and light physical activity were independently associated with markers of cardiometabolic health in young, adult women. Our data suggest that VO2peak and body composition may be important mediators of these associations. Decreasing sedentary behavior and increasing light physical activity may be important for maintaining cardiometabolic health in young, adult women.
Objective: This study investigates the factors influencing sedentary behavior in older adult Chinese stroke patients using decision trees and logistic regression models.
Methods: Convenience sampling method was employed to enroll 346 respondents aged ≥60 years with stroke from the Department of Neurology of three tertiary-level A hospitals in Heilongjiang province, based on the inclusion criteria. The Sedentary Behavior Questionnaire for Older Adults, the International Physical Activity Questionnaire Short Form (IPAQ-S), the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Depression Scale (SDS), and the Social Support Scale (SSRS) were used to assess sedentary behavior, physical activity level, sleep quality, depressive symptoms, and social support, respectively.
Physical activity and sedentary behavior have significant prognostic importance in survivors of breast cancer. However, not much is known about physical activity and sedentary behavior in the midwestern United States for patients who have breast cancer. This study provides patient-reported physical activity and sedentary behavior from a cohort of patients from the midwestern United States.

Although exercise supports the physical function and health of older people living with HIV (PLWH), less than half of PLWH globally achieve recommended levels of activity. A qualitative descriptive design was used to determine what motivates sedentary PLWH, 50 years and older, to participate in an exercise trial. Interviews were conducted with PLWH who participated in an exercise trial (n = 30) and PLWH who declined enrollment in the same exercise trial (n = 4).
Introduction: The associations between sedentary lifestyles, physical activity and the risk of respiratory diseases are crucial areas of medical and health research. Despite numerous studies, uncertainties and controversies regarding causal relationships persist. We utilized Mendelian randomization (MR) analysis, an advanced statistical tool, to further investigate causal links.
Objective: Aim: The aim of the study was to explore the factors that influence the development of a caring attitude toward health in modern youth as a foundation for an active life stance.
Patients And Methods: Materials and Methods: Various methods, including analysis of normative and scientific sources, systematic analysis, and empirical research, were employed. An anonymous survey of 114 pedagogical students was conducted to assess how much they value their health.
