The causal relationships between leisure-time physical activity and body mass index in adulthood: a triangulation study

Previous studies have presented conflicting findings regarding the potential causal relationships between leisure-time physical activity (LTPA) and body mass index (BMI). Here, we use individual-level data and apply a triangulation framework that incorporates three complementary methods to investigate the bidirec...

Causal Effects of Physical Activity and Sedentary Behavior on Healthcare Costs

The Effect of Cardiorespiratory and Muscular Fitness on Healthcare Costs Among Adults: A Triangulation Study.

The hypothesis that better CRF and MF reduce healthcare costs is partially supported, as trends were observed in subgroups and across cost categories, although statistical significance was primarily reached for CRF.

Longitudinal changes of cardiorespiratory fitness are associated with cardiovascular disease and mortality: evidence from the UK Biobank.

Adolescent weight gain trajectories and their associations with biological aging: a genetically informed study.

Higher level of adolescent BMI partly mediated the association between higher BMI-PRS and accelerated biological aging from late adolescence to middle adulthood, indicating that high BMI in adolescence may accelerate biological aging.
