Bikeability Study: Two papers published

Back when I was in graduate school some colleagues and I were funded to conduct a survey of bicyclists residing in Jefferson County, Alabama (Birmingham) and Travis County, Texas (Austin). Rich data was collected on how, where, and why people ride in two areas with very different cycling cultures. I was able to write two of my dissertation papers using these data, and they were turned into manuscripts that have both been published.

The first, titled “Perceived Social and Built Environment Correlates of Transportation and Recreation-Only Bicycling Among Adults” was published in the CDC journal Preventing Chronic Disease. In this paper, we explored the association between perceived social and built environment factors, such as residential density, traffic safety, destination, connectivity, safety from crime, aesthetics, and bicycle infrastructure, with total, transportation, and recreation bicycling. We found that bicycling for transportation is associated with different perceived environmental factors than is recreation-only bicycling, with some significant modification by sex. The full paper, which is available via open access, can be found here: https://www.cdc.gov/PCD/issues/2018/18_0060.htm

The second, titled “Bikeability: Assessing the Objectively Measured Environment in Relation to Recreation and Transportation Bicycling” was published in the journal Environment & Behavior. For this paper, we examined the actual rather than perceived environment in relation to domain specific bicycling. Specifically, we examined the association between objectively measured environmental variables and transportation and recreation bicycling frequency, and to develop transportation and recreation bikeability indices. We found that no objectively measured environmental variables were associated with recreation bicycling, but many were for transportation bicycling. The final transportation bikeability index included the combined effect of bicycle lanes, residential density, population density, ozone level, distance to transit, parks, and tree canopy coverage, and was found to have a significant direct association with any past-year transportation bicycling and transportation bicycling frequency.

Two new publications out in the world

I'm excited to announce that two manuscripts for which I am first author have been recently published!

The first is "Intrapersonal and Environmental Correlates of Bicycling in U.S. Adults", published in print in the American Journal of Preventive Medicine March issue. This paper examined the association between multilevel factors and bicycling for recreation and transportation in a nationally representative sample from the 2012 National Survey of Bicyclist and Pedestrian Attitudes and Behaviors. Results indicated that there were significant differences between bicyclists and non-bicyclists, as well as between recreation and transportation bicyclists. The paper can be accessed via ScienceDirect here.

The second is "Reliability and One-Year Stability of the PIN3 Neighborhood Environmental Audit in Urban and Rural Neighborhoods", just published online in the Journal of Urban Health. This study described the reliability and stability of the PIN3 environmental audit instrument in both urban and rural neighborhoods. It was determined that the PIN3 instrument is a reliable and stable audit tool for studies assessing neighborhood attribute s in urban and rural environments.

Ride Report: Mobile app user guide

I have a new article published online about the Ride Report App. If you're not familiar, Ride Report is a smartphone application that automatically tracks bicycling and other transportation modes. It's a great way to track your riding without having to remember to start and stop an app (like you need to do with Strava or a gps device).

I personally find it silly and annoying to use a gps for my daily bike commutes or for the quick trip to the grocery store. Ride report is a great resource for me to keep track of every mile that I've ridden, rather than just the "fitness" rides I track using a gps. Case in point: according to Ride Report, so far this year I've ridden 2,592 miles; in comparison, Strava has me at 1,860 miles. Those little transportation rides really add up!

Anyway, check out the article at the British Journal of Sports Medicine, and also check out the Ride Report app (for Apple and Android devices)!

Associations of Physical Activity, Sedentary Time, and Screen Time With Cardiovascular Fitness in United States Adolescents: Results from the NHANES National Youth Fitness Survey (NNYFS)

I am excited to report that my journal article using data from the NHANES National Youth Fitness Survey to examine the associations between physical activity, sedentary time, and screen time with cardiovascular fitness is published ahead of print in the Journal of Physical Activity and Health. You can find the abstract (and article if you have access or are willing to pay for it) at the following address:

Welcome!

I've created a website to share my research, and possibly general ramblings. You might be a friend, family, study participant, or complete stranger, but regardless of who you are or why you've come, thank you for the visit.
