For the world’s largest ageing population, personalising physical activity guidance by baseline cardiovascular risk could reshape public health strategies in China and beyond.
Chinese scientists have demonstrated, through the large-scale China-PAR project, that the protective effect of physical activity against atherosclerotic cardiovascular disease is significantly modified by an individual’s predicted baseline cardiovascular risk. This finding, published in the Journal of Sport and Health Science, draws on longitudinal data from Chinese cohorts and challenges the one-size-fits-all approach to exercise recommendations. The research suggests that while increasing physical activity consistently lowers cardiovascular risk, the magnitude of benefit is greater among those with a higher initial risk profile, meaning that targeted exercise interventions could yield disproportionately large gains for China’s most vulnerable populations.
The study represents a significant methodological advance because it integrates dynamic risk prediction with behavioural exposure, offering a framework that is directly actionable for clinicians and policymakers. For China, where the burden of cardiovascular disease is rising alongside rapid urbanisation and lifestyle change, these results provide a rationale for prioritising physical activity programmes among those identified as high-risk by simple, scalable risk scores. Globally, the work reinforces the need to move beyond generic exercise guidelines toward stratified, precision-based prevention strategies that account for individual physiological vulnerability.
Why it matters:
For researchers and healthcare strategists, this evidence supports the integration of cardiovascular risk screening with physical activity counselling, a step that could improve resource allocation in public health systems. For professionals in health technology and insurance, the risk-modified benefit curve offers a quantitative basis for designing personalised wellness programmes and risk-adjusted premium models tailored to China’s diverse population.
