Chan School of Public Health, Boston, the SPORT Research Group and CERNEP Research Center at the University of Almería (Spain), and Erasmus MC University Medical Centre, Rotterdam, the Netherlands. It was <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2810197">published online</a> on in JAMA Network Open.</p> <h2>LIMITATIONS:</h2> <p>The study only accounted for confounders at baseline, does not establish causation, and utilized unvalidated questionnaires to gather information on physical activity.</p> <h2>DISCLOSURES:</h2> <p>Individual authors report receiving financial support, but there was no specific funding for this study. Dr. Estévez-López reports no relevant financial conflicts.
