🏃‍♀️+🤳+🛌Concurrent adherence to all three guidelines decreased by 2% (9% in 2018 to 7% in 2022. By understanding the natural co-dependence of 24hr movement behaviors we can begin to improve existing programs/interventions or develop new ones!

Do you use compositional data analysis to examine 24-hour movement behaviors in relation to health? Consider reading our recent review of reporting practices across 102 studies. TLDR - we need to improve! Recommendations provided. https://t.co/FcdeYx9YrA

New study out today in @AmJPrevMed. We investigated out-of-school and weekend activities that contribute to meeting 24-hour movement guidelines among US adolescents. Alongside sports, community service/volunteering was a standout! https://t.co/WuocThKI4D

This was a big undertaking which included national/international collaboration. It would not have been possible without relying on previous work from ~500 authors, the Delphi panel of experts, and the co-authors who helped put everything together for the final consolidation.

New study by @Lauren_vonK! We wanted to understand how researchers balance best practices of intervention development alongside the realities of limited funding, time, and other challenges. Results come from a survey of 430 PIs funded by the NIH.
