Association between physical activity and cardiovascular-kidney-metabolic syndrome in older Chinese adults
Background: Cardiovascular-kidney-metabolic (CKM) syndrome represents a new framework to address the non-communicable disease burden in ageing populations. However, evidence on the association between physical activity and the integrated CKM syndrome is scarce, particularly among older Asian adults. We aimed to investigate this association in a large sample of older Chinese adults. Methods: This cross-sectional study utilised data from the China …
Association of changes in overall and specific leisure activities with long-term all-cause mortality in older adults
Background: Leisure activities (LAs) are vital for healthy ageing and are linked to lower mortality risk in older adults. However, most previous longitudinal studies have assessed LAs at only one time point. We aimed to explore the impact of dynamic changes in LAs on subsequent all-cause mortality among older adults. Methods: We enrolled 21 262 older adults who had participated in the six waves of the Chinese Longitudinal Healthy Longevity Survey…
Impact of changes in leisure activities on incident disability among older adults
Background: As research has shown that participation in leisure activities (LAs) is closely related to health outcomes in later life, we explored the associations between dynamic changes in LAs and disability in activities of daily living (ADL) in older people. Methods: We enrolled 11627 older adults free of disability from six waves in the Chinese Longitudinal Healthy Longevity Survey (1998, 2000, 2002, 2005, 2008, and 2011). All participants co…
Associations between upper limb flexibility and all-cause mortality in the oldest-old

This study aimed to explore the association of ULF with all-cause mortality in community-dwelling oldest-old in China. Methods: A total of 21 861 older adults aged ≥80 years were enrolled from five waves of the Chinese Longitudinal Healthy Longevity Survey. The assessment of ULF at baseline involved three objective physical tas…
Mediating effects of physical activities and cognitive function on the relationship between dietary diversity and all-cause mortality in community-dwelling older adults
Background: Although dietary diversity (DD) has been confirmed to be associated with multiple health outcomes and longevity in older people, the related mechanisms have not been elucidated. In this study, we explored the mediating roles of physical activities and cognitive function in the relationship between DD and all-cause mortality. Methods: We recruited 34 068 community-dwelling older adults aged ≥60 years from the Chinese Longitudinal Healt…
Self-selection or situational stratification? A quasiexperimental study on social class differences in health behaviors in China
Fundamental cause theory suggests that differences in social status lead to health inequalities, with lifestyle serving as the intermediary mechanism. This study uses multiple waves of data from the China Family Panel Studies (CFPS) to first explore differences in drinking, smoking, and physical exercise across different social classes and finds that managers have significantly greater tendencies toward risky health behaviors such as drinking and…

Modeling the Radiocarbon Reservoir Effect in Lacustrine Systems
The modern water (both pre- and post-atmospheric nuclear testing) of most lakes has an anomalously old apparent radiocarbon age due to what is commonly referred to as the “reservoir effect.” In contrast to marine settings, this 14 C-offset phenomenon is primarily caused by pre-aged carbon discharged to lakes by rivers and/or groundwater. In this paper, a 2-component box model based on the principle of 14 C mass balance in lake water and in the ea…
