Prof Philippe Gradidge

Philippe Jean-Luc Gradidge is a South African health scientist affiliated with the University of the Witwatersrand, where he contributes to research in exercise science, public health, and chronic disease prevention. His scholarship bridges clinical exercise physiology and population health, with a strong emphasis on cardiometabolic risk reduction in underserved and vulnerable communities.

His publications highlight expertise in physical activity promotion, workplace and community-based interventions, and task-shifting strategies using community health workers. He has led and collaborated on trials examining high-intensity and moderate exercise training, sit-to-stand workstations, and home-based screening initiatives, demonstrating practical approaches to reducing sedentary behaviour, hypertension, and obesity in South African contexts.

Gradidge also contributes to large international cohort analyses, including work within the Women’s Health Initiative, exploring socioeconomic pathways, inflammation, arthritis, cardiovascular outcomes, and post-viral sequelae in postmenopausal women. This body of work reflects strengths in epidemiological methods, longitudinal modeling, and translational research aimed at informing equitable prevention strategies for non-communicable diseases.
