Happy to share our new study comparing perceptions of social and built environments between rural and urban parents in the US. We also explore how these perceptions shape youth physical activity differently across the rural-urban continuum. doi.org/10.1016/j.pm...

Recent blog post I wrote for the Michael & Susan Dell Center for Healthy Living about the importance of out-of-school activity promotion and 24hr movement behavior guideline adherence among children and adolescents. sph.uth.edu/research/cen...

Finally, it’s not impossible to get R01 funding without having had a previously-funded NIH grant. You just need to demonstrate strong prelim. evidence for your project (plus all the other stuff they’re looking for). If you’re coming up on losing your ESI status I would go for the R01 if you can.

R03s, as someone else mentioned as well, are a good option for smaller projects, but your funding will be limited.

As someone else mentioned, K01s are a good mechanism as well. They require an additional training component to be written and you need ~75% protected time for them. They can be up to 5 years and are a good jumping off point for your R01.

I’ve tried to develop 2-3 R21s and have them cycle through the submission and resubmission process. They’re typically 2 years of funding to establish some preliminary evidence for a R01 submission, but the writing process is good practice for the R01.

Unfortunately, there isn't much out there about how walking/biking to school might play a role in the broader 24hr cycle... but that's a good idea for a study.

There are also approaches like WOS and CSPAP that factor in active commuting as an effective way to promote PA among children. The National Center for Safe Routes to School is a great place to start for broader resources: www.saferoutesinfo.org

There is a ton of literature out there about active commuting to school. A review published last year that found if kids actively commuted to/from school, it could contribute to about 50% of meeting PA guidelines: pubmed.ncbi.nlm.nih.gov/37497601/

New study out in AJPM. 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. www.ajpmonline.org/article/S074...

Out-of-school Activities and Adherence to 24-hour Movement Guidelines

The purpose of this study was to explore associations between participation in out-of-school/weekend organized activities and adherence to the 24-hour movement guidelines among US adolescents.

Follow-up from the pre-print I posted awhile back. If you work with 24hr movement behavior data, our newest publication might be of interest! In it, we demonstrate how decisions made before analyzing 24hr data influence guideline adherence and health outcomes. doi.org/10.1186/s441...
