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.

For sure! Let me know if you ever want to chat. Happy to share more resources.

Here's one with adult participants from the UK Biobank, however. journals.plos.org/plosone/arti...

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/

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.

Background Despite the widespread endorsement of 24-h movement guidelines (physical activity, sleep, screentime) for youth, no standardized processes for categorizing guideline achievement exists. The...

New pre-print up! We took a look at how data handling decisions influence interpretations around meeting 24hr movement guidelines and associations with health outcomes in children.
What does it mean to use the mean? The impact of different data handling strategies on the proportio...
