In general, this is a study of significant scientific interest in the field of public health related to healthy lifestyles, characterized by a robust methodological design that strengthens and expands the existing body of evidence.
Specifically, this work presents up-to-date estimates that provide evidence on health outcomes associated with small changes in physical activity patterns and sedentary behavior in high-income countries. The authors highlight two key issues: first, they clarify that these results are intended to help understand general benefits for society and should not be used to provide advice or personalized exercise plans for a specific individual. Second, they emphasize the need to further develop research in low- and middle-income countries, where demographic structures, levels of physical activity, and epidemiological risk profiles may differ substantially from those observed in the study cohort; it would also be necessary to assess the feasibility and viability of replicating a study with similar characteristics in these countries.
