Objective
Understanding how recreational cannabis legalization may impact cannabis use disorder (CUD) among adolescents and young adults is key to developing an appropriate public health response. This research investigates whether associations among adolescent and young adult perception of risk of harm from cannabis use, prevalence of past-month c...
Objective
Lung cancer is a leading cause of cancer death in the United States. Exposure to outdoor air pollution (OAP) is associated with increased lung cancer incidence, however little is known about the association of OAP and survival after diagnosis.
Methods
We investigated the effects of OAP and lung cancer survival in Pennsylvania using data...
Background
It is known that geographic location plays a role in developing lung cancer. The objectives of this study were to examine spatio-temporal patterns of lung cancer incidence in Pennsylvania, to identify geographic clusters of high incidence, and to compare demographic characteristics and general physical and mental health characteristics i...
This study leverages data from a pilot randomized controlled trial to investigate whether the effectiveness of a text-delivered mHealth intervention targeting adolescent depression and anxiety differs according to residential- and activity space-based measures of exposure to community-level socioeconomic disadvantage. For depression, we find that i...
Lead (Pb) soil contamination in urban environments represents a considerable health risk for exposed populations, which often include environmental justice communities. In Philadelphia, Pennsylvania (PA), Pb pollution is a major concern primarily due to extensive historical Pb-smelting/processing activity and legacy use of Pb-based paints and leade...
Objective
This short communication reports on the association of annual measures of young adult (age 18-24) past month cannabis use with cannabis use disorder (CUD) treatment admissions by state in the U.S. from 2008-2017.
Methods
Annual data on percentage of past month cannabis use and the total number of CUD treatment admissions among young adul...
To illustrate methods for assessing environmental exposures associated with lung cancer risk, we investigated anthropogenic based air pollutant data in a major metropolitan area using United States-Environmental Protection Agency (US-EPA) Toxic Release Inventory (TRI) (1987–2017), and PM 2.5 (1998–2016) and NO 2 (1996–2012) concentrations from NASA...
Background:
Water total trihalomethanes (TTHMs) are disinfectant byproducts found in municipal water supplies. TTHM exposure has been linked to cancer and may be associated with adverse reproductive outcomes. A non-optimal cervicovaginal microbiota and low cervicovaginal beta-defensin-2 levels are associated with increased risk of spontaneous pret...
While urban greenspace is increasingly recognized as important to mental health, its role in substance use is understudied. This exploratory study investigates the interaction of greenspace with peer network health, sex, and executive function (EF) in models of substance use among a sample of disadvantaged, urban youth. Adolescents and their parent...
This study investigated the geographic variation and the clustering of lung cancer incidence rates in Philadelphia and the surrounding areas using addresses at the time of diagnosis. Using 60,844 cases from Pennsylvania Cancer Registry, we calculated and mapped the age-adjusted incidence rates for five Pennsylvania (PA) counties near Philadelphia b...
To assess risk factors that contribute to lung cancer burden in the Abramson Cancer Center (ACC) catchment area, we integrated geospatial data of exposure to pollutants from publicly available EPA and NASA datasets. The study area covers the 421 zip codes that make up the 12 counties of the catchment area from which most of the ACC patients come. T...
Pollution from heavy metals in urban environments is a topic of growing concern because many metals, including Pb and Cr, are a human health hazard. Exposure to Pb and Cr has been linked to the inhibition of neurological development as well as toxic effects on many organs. Yellow traffic paint (YTP) is a mixture that contains organic polymers, bind...
Background
: Over half of the world's population now lives in urban areas, and this proportion is expected to increase. While there have been numerous reviews of empirical studies on the link between nature and human health, very few have focused on the urban context, and most have examined almost exclusively cross-sectional research. This review i...
Despite the success of recent efforts to increase access to improved water, sanitation, and hygiene (WASH) globally, approximately one-third of schools around the world still lack adequate WASH services. A lack of WASH in schools can lead to the spread of preventable disease and increase school absences, especially among women. Inadequate financing...

... However, as environmental degradation continues while people seeking higher life quality, whether environmental pollution would inhibit urbanization remains arguable. Exposure to air pollution has been associated with a wide range of health problems, including childhood asthma (Gasana et al., 2012), worsening asthma (Yang and Omaye, 2009), impaired lung function (Chung et al., 2022;McKeon et al., 2022), hospitalization (Renzi et al., 2022), limited physical activity (Tainio et al., 2021), and cardiovascular disease (Samet and Krewski, 2007;Shah et al., 2013). Due to the increasingly severe environmental pollution in urban areas, the phenomenon of "counter urbanization" has been observed in many regions (particularly in more developed countries), which is manifested as the urban residents migrating to suburbs, small and medium-sized cities, or rural areas (Berry, 1980;Wu et al., 2020a). ...
... Our context-dependent results point to the importance of tailoring mHealth interventions to the context [100]. If the #LIFEGOALS intervention would have included information and tips on how to be more physically active or how to reduce sedentary behavior in times of the pandemic (i.e., anticipating social and environmental limitations), this might have had more beneficial effects on lifestyle and mental health. ...
... For example, in Santa Ana, CA (U.S.), rental status was related to elevated concentrations of heavy metals in soil such as Pb (Masri et al 2021). However, this was not the case in Philadelphia, PA (U.S.) for both blood lead levels (BLLs) and Pb risk factors (O'Shea et al 2021, Caballero-Gómez et al 2022, which were more related to home ownership than those renting a home. This was likely because of past housing policy in Philadelphia that was different from that in Santa Ana (O'Shea et al 2021, Caballero-Gómez et al 2022. ...
... Although the number of people with CUD seeking treatment is increasing in Europe and North America, the overall utilization of CUD-specific treatments is relatively low and the majority of the affected individuals is untreated (9,10). In the United States, CUD treatment seeking behavior and CUD treatment admissions among young adults (aged 18 to 24 years) have even declined (11). On the other hand, effective treatment options for CUD are limited and focus primarily on psychosocial interventions, including motivational enhancement therapy, cognitive behavioral therapy and contingency management (12). ...
... As important precursors of PM2.5 and O3, ambient volatile organic compounds (VOCs) play a critical role in the formation of secondary air pollutants [3,4]. In addition, some studies have shown that many VOC species are hazardous air pollutants (HAPs) [5,6], such as formaldehyde, benzene, chloroform, etc., which are classified as carcinogens by the International Agency for Research on Cancer (IARC) [7,8]. ...
... There are various health benefits associated to contact with nature, including better control/prevention of chronic diseases, decreased mortality, improved mental health, greater social cohesion, and reduced health inequalities, among other benefits [6,7]. In childhood, living or playing in natural environments seems to help them to acquire skills, increase their self-esteem and resilience strategies, make them more independent, stimulate more cooperative and creative forms of play, and prevent the use of legal and illegal drugs [8,9]. All these positive childhood experiences in nature influence the community, which promotes pro-environmental behavior from childhood to adulthood [10]. ...
... Some elements in road sediment commonly linked to anthropogenic sources include Cd, Cr, Cu, Pb, and Zn. Specific anthropogenic sources from vehicles, households, industry, and commercial activity include, but are not limited to: vehicle traffic and coal combustion for Cd (e.g., Zgłobicki et al., 2019); house siding and brake wear for Cu (e.g., Davis et al., 2001); house siding and tire wear for Zn (e.g., Davis et al., 2001); steel facilities (e.g., Dietrich et al., 2019) and lead chromate (PbCrO 4 ) particles in road paint for Cr (e.g., White et al., 2014;O'Shea et al., 2021a); while Pb has sources including PbCrO 4 (e.g., White et al., 2014), lead wheel balancing weights in vehicles (e.g., Ayuso and Foley, 2020;Hwang et al., 2016), other Pb-bearing paint components (e.g., Tchounwou et al., 2012), or past deposition of leaded gasoline that may be resuspended as soil particles in the environment (e.g., Laidlaw et al., 2012). Thus, potential anthropogenic sources of heavy metals are numerous in urban settings. ...
... Building a fuller understanding of the impact of the environmental context on mental health has become a priority for the global mental health research agenda [5,6]. Numerous recent reviews evidence the importance of the environment for mental health through impacts associated with, for example, climate change [7] and related flooding events [8,9], air pollution [10] and access to urban green space [11][12][13]. In the social sciences, this impact is often explored via frameworks that consider both the nature experience and nature exposure pathways linking environments with health and wellbeing [14,15]. ...
... A recent systematic review identified a lack of published information about WASH programs in schools compared with WASH programs aimed at communities (McGinnis et al. 2017). There are even fewer studies on long-term sustainable actions to guarantee the WT. ...
