- Study examines the dose-response relationship between light-intensity physical activity (LPA) and all-cause mortality across different levels of moderate-to-vigorous physical activity (MVPA).
- Used UK Biobank data (n=71,715) with accelerometer-measured LPA and MVPA, and mortality data from death registries.
- Found a non-linear dose-response effect of LPA on mortality, with diminishing effects as MVPA levels increased.
- Achieving WHO-recommended MVPA levels (22-44 min/day) combined with LPA (195-225 min/day) significantly reduces 10-year mortality risk.
- Highlights the importance of integrating LPA into public health strategies, especially for individuals with low MVPA or those unable to engage in higher-intensity activities.
