Telomeres, genetic structures regulating cell growth and senescence, are one pathway through which the exposome may impact health. Greenspace exposure, representing the amount of green areas in one's neighborhood, is one component of the exposome and has been associated with multiple health benefits. To investigate the potential link between greenspace exposure and telomere length, we analyzed data from the 1999-2001 National Health and Nutrition Examination Survey (NHANES) sample. Our study examined individual, risk, and contextual factors. We found that greater greenspace exposure in one's neighborhood was associated with longer telomere lengths when considering individual and risk factors, suggesting a positive effect of living in greener neighborhoods. However, this relationship became non-significant when contextual factors, such as air pollution and deprivation, were included in the analysis. These findings highlight a complex relationship between greenspace and telomere length, warranting further research to explore contextual factors in detail.}, journal={SCIENCE OF THE TOTAL ENVIRONMENT}, author={Ogletree, S.

There is a need for evidence for parks and recreation departments and agencies to base decisions when adapting policies in response to the rapid change in demand and preferences during the pandemic. The application of social media data analytic techniques permits a qualitative and quantitative big-data approach to gain unobtrusive and prompt insights on how parks are valued. This study investigates how public values associated with NYC parks has shifted between pre- COVID (i.e., from March 2019 to February 2020) and post- COVID (i.e., from March 2020 to February 2021) through a social media microblogging platform -Twitter. A topic modeling technique for short text identified common traits of the changes in Twitter topics regarding impressions and values associated with the parks over two years. While the NYC lockdown resulted in much fewer social activities in parks, some parks continued to be valued for physical activity and nature contact during the pandemic. Concerns about people not keeping physical distance arose in parks where frequent human interactions and crowding seemed to cause a higher probability of the coronavirus transmission. This study demonstrates social media data could be used to capture park values and be specific per park. Results could inform park management during disruptions when use is altered and the needs of the public may be changing.}, journal={LANDSCAPE AND URBAN PLANNING}, author={Huang, Jing-Huei and Floyd, Myron F. and Tateosian, Laura G. and Hipp, J.

It has been hypothesized that mixed-use land development could increase park use as a result of mixed-use neighborhoods being consistently activated throughout the day, but the results of previous research on this question have been inconsistent and the mediational role of neighborhood activation has not been tested. This study leverages data from Google Places Popular Times and the National Establishment Time Series to directly test the mediational role of the daily temporal distribution of neighborhood activation, to construct a novel measure of commercial activity diversity, and to help disentangle built-environment density from commercial diversity. Park use data was measured from 10,004 systematic observations of 20 neighborhood parks in New York City in the spring and summer of 2017. The hypothesis that commercial activity diversity is positively associated with park use was not supported in any models. However, a positive relationship between built-environment density and park use was found, which may help to explain prior inconsistent findings.}, journal={PREVENTIVE MEDICINE REPORTS}, author={Fry, Dustin and Hipp, J.

Despite urban parks being a great venue for physical activity, children change both the frequency of park use and their park use habits as they age into adolescence. However, little is known about how these differences vary by gender and how distinct race/ethnicity groups differentially change their park habits. This study analyzed the differences in park use and per capita energy expenditure between children and teenagers of different gender and race/ethnicity backgrounds. Using the System for Observing Play and Recreation in Communities (SOPARC), systematic observations were conducted in 20 New York City parks in 2017, located in low-income areas with high presence of Latino or Asian residents. A total of 9963 scans in 167 distinct target areas counted 16,602 children (5-10 years old) and 11,269 teenagers (11 or older). Using adjusted marginal means, we estimated the number of park users of each age range, gender, and race/ethnicity expected to be found in each park activity setting. Teenagers of both genders and most race/ethnicity groups were less likely to be in a park and had lower per capita energy expenditure, compared with children. The difference in park attendance was greater than the difference in per capita energy expenditure. Dissimilarities were clearly gendered and race/ethnicity dependent. Asian and Latino females showed the greatest divergence between childhood and adolescence. African American boys were the only group to show a positive age contrast in park attendance and per capita energy expenditure.}, number={5}, journal={Journal of Urban Health}, publisher={Springer Science and Business Media LLC}, author={Marquet, Oriol and Hipp, J.

Given the importance of parks as settings for outdoor recreation and physical activity, the presence of crime may have a detrimental effect on public health. This study uses objective police crime reports and observational park use data to assess type of crime and the time when the crime was committed effects on park user behaviors in 20 parks located in low-income neighborhoods in New York City. The System for Observing Play and Recreation in Communities (SOPARC) was used to assess the number of park users and their physical activity during 78 park visits in Spring 2017. The association between crime rates and park use was assessed using two types of crimes (violent and property crimes). The timing of the crime was assessed using the crimes committed within periods of one week, one month, and three months prior to the visit to the park. By including objective measures of crime together with the exact time on which they were committed, we were able to analyze the short and long term effects of crime on park behavior. Overall, there was a consistent negative association between crime and park use. This relationship was stronger at the 1 month and 3 months' period and weaker at the 1-week period. Violent crimes were strongly associated with lower park use, and crimes proved to be associated with child park use to a greater degree. Girls were more affected by crime than boys.}, journal={Preventive Medicine}, publisher={Elsevier BV}, author={Marquet, Oriol and Hipp, J.
