Neural Responses to Auditory Food Stimuli Following Cognitive Behavioral Therapy for Binge-Eating Disorder.

OBJECTIVE: Adults with binge-eating disorder (BED), compared with those without BED, demonstrate higher blood-oxygen-level-dependent (BOLD) response to food cues in reward-related regions of the brain. It is not known whether cognitive behavioral therapy (CBT) can reverse this reward system hyperactivation. This randomized controlled trial (RCT) assessed changes in BOLD response to binge-eating cues following CBT versus wait-list control (WLC). METHOD: Females with BED (N = 40) were randomized to CBT or WLC. Participants completed assessments at baseline and 16 weeks including measures of eating and appetite and functional magnetic resonance imaging (fMRI) to measure BOLD response while listening to personalized scripts of binge-eating and neutral-relaxing cues. Data were analyzed using general linear models with mixed effects. RESULTS: Overall retention rate was 87.5%. CBT achieved significantly greater reductions in binge-eating episodes than WLC (mean ± standard error decline of 14.6 ± 2.7 vs. 5.7 ± 2.8 episodes in the past 28 days, respectively; p = 0.03). CBT and WLC did not differ significantly in changes in neural responses to binge-eating stimuli during the fMRI sessions. Compared with WLC, CBT had significantly greater improvements in reward-based eating drive, disinhibition, and hunger as assessed by questionnaires (ps < 0.05). DISCUSSION: CBT was effective in reducing binge eating, but, contrary to our hypothesis, CBT did not improve BOLD response to auditory binge-eating stimuli in reward regions of the brain. Further studies are needed to assess mechanisms underlying improvements with CBT for BED. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03604172.

Factors associated with racial and ethnic disparities in chronic pain after acute traumatic injury.

BACKGROUND: Chronic pain represents a substantial health burden and source of disability following traumatic injury. This study investigates factors associated with racial and ethnic disparities in chronic pain. METHODS: Prospective, longitudinal, panel study. Seriously injured patients were recruited from two trauma centres in the Northeastern and Southwestern USA. Data from medical records and individual surveys were collected in-hospital, and at 3-month and 12-month postinjury from a balanced cohort of non-Hispanic black, non-Hispanic white and Hispanic patients. We used linear regression to estimate the associations between race and ethnicity and 3-month and 12-month pain severity outcomes. We grouped all available cohort data on factors that theoretically influence the emergence of chronic pain after injury into five temporally ordered clusters and entered each cluster sequentially into regression models. These included: participant race and ethnicity, other demographic characteristics, preinjury health characteristics, acute injury characteristics and postinjury treatment. RESULTS: 650 participants enrolled (Hispanic 25.6%; white 38.1%; black 33.4%). Black participants reported highest relative chronic pain severity. Injury-related factors at the time of acute hospitalisation (injury severity, mechanism, baseline pain and length of stay) were most strongly associated with racial and ethnic disparities in chronic pain outcomes. After controlling for all available explanatory factors, a substantial proportion of the racial and ethnic disparities in chronic pain outcomes remained. CONCLUSION: Racial and ethnic disparities in chronic pain outcomes may be most influenced by differences in the characteristics of acute injuries, when compared with demographic characteristics and postacute treatment in the year after hospitalisation.

Spiritual coping behaviors among injured urban black men in Philadelphia.

PURPOSE: High rates of firearm injury among urban Black men in the US can lead to long physical and psychological recovery times, worsened by limited access to mental health services. Spirituality can propel positive thoughts, actions, perceptions and behaviors about self and others yet how it is used among Black men recovering from firearm injury is underexplored. This study examined the role of spirituality in the recovery of Black male survivors of firearm injury. METHOD: Ten injured urban Black men in Philadelphia were interviewed using descriptive phenomenology. A subset of participants from the Emotional Responses and Recovery from Injury in Urban Black Men study who agreed to be recontacted for future studies were enrolled. Informed consent was obtained, semi-structured interviews were conducted via phone and were audiotaped, transcribed, and de-identified. Thematic content analysis was used to understand perceptions of spirituality and to identify spiritual coping behavior themes. RESULTS: Findings suggest that injured urban Black men engaged in theistic and non-theistic spiritual activities that resulted in positive character development, reduced risk of re-injury, hope, improved mental health and social bonds. CONCLUSION: Spirituality may serve as a protective factor against firearm re-injury or retaliation by promoting desired behaviors and mental health among injured urban Black men. Combining culturally sensitive spiritual resources and psychotherapy may lead to effective trauma-informed care in addressing spiritual and existential challenges of injured urban Black men who may find spirituality important.

Mental health outcomes in formerly incarcerated Black men: A systematic mixed studies review.

AIMS: The aim of this review was to evaluate the current state of scientific knowledge describing the mental health of Black men who have experienced incarceration. DESIGN: This systematic mixed studies review employed a sequential explanatory design integrating quantitative and qualitative published research. DATA SOURCES: PubMed, CINAHL, PsycINFO, Social Work and Criminal Justice databases were searched using search terms addressing core constructs of mental health, Black men, incarceration and re-entry, January 2010 through October 2021. REVIEW METHODS: Articles identified through a search protocol were screened for inclusion as: peer-reviewed original research, published in English and relevant to the mental health of formerly incarcerated Black men in the United States. RESULTS: Twenty-three articles met inclusion criteria. Quantitative findings demonstrated significant associations between incarceration history and poor mental health, including higher levels of psychological distress, increased severity of depressive and PTSD symptoms, and delayed mental health treatment. Discrimination, negative police encounters, solitary confinement and difficulty finding employment were associated with the relationship between incarceration and mental health outcomes. Four themes were identified from the qualitative synthesis: (1) Social Determinants of Mental Health (2) Pushing Through Emotional Despair (3) Challenges to Healthcare Engagement and (4) Gender, Race and Intersections between Social Identities. IMPACT: The United States has the highest rate of incarceration in the world and disproportionately incarcerates Black men. This review contextualizes the relationship between incarceration history and mental health in the lived experiences and perspectives of formerly incarcerated Black men. Findings indicate the need for interventions to support mental health needs and prevent downstream health consequences in this population. CONCLUSION: Mental health concerns are pervasive in formerly incarcerated Black men; to address key gaps in current scientific understandings future research should focus on how Black men navigate help-seeking experiences and use mental health services in the context of an incarceration history.

A longitudinal analysis of violence and healthcare service utilization in Mexico.

OBJECTIVES: We analyze the degree to which community violence in Mexico, largely due to organized crime violence, affects health care service utilization. METHODS: This study exploits temporal and geographic variation in monthly county-level homicide rates, matching outpatient service utilization from individual longitudinal measures. Sensitivity analyses test for an age specific concentration of violence, respiratory conditions that are likely unrelated to violence, insurance status and health center availability per capita. We test for distributional responses to violence by urban and rural localities. RESULTS: The likelihood of service utilization increases by 5.2% with each additional homicide per 100,000. When we include self-reported health conditions in the model, our main coefficient remains significant at 4.5%. We find no added effect to our results from interaction terms for age specific concentration of violence, respiratory conditions, insurance status, or health center availability. A substantial increase of 11.7% in the likelihood of service utilization occurs in localities with > = 100,000 inhabitants, suggesting that service utilization is sensitive to the location of violence. CONCLUSIONS: Results highlight the relationship between and increase in violence at the local level and an increase in health care service utilization. This study is among the first to examine this relationship empirically in Mexico. Future research is needed to shed more light on this relationship and its mechanisms.

Differential Pain Presentations Observed across Post-Traumatic Stress Disorder Symptom Trajectories after Combat Injury.

OBJECTIVE: This study evaluated the association between pain outcomes and post-traumatic stress disorder (PTSD) symptom trajectories after combat-related injury, while adjusting for receipt of regional anesthesia (RA) soon after injury. METHODS: The PTSD symptom trajectories of N = 288 combat-injured service members were examined from within a month of injury up to two-years after. Linear mixed-effects models evaluated the association between PTSD symptom trajectories and average pain and pain interference outcomes while adjusting for receipt of RA during combat casualty care. RESULTS: Four PTSD trajectories were characterized: resilient, recovering, worsening, and chronic. Differential pain presentations were associated with PTSD symptom trajectories, even after adjusting for receipt of RA. Compared to those with a resilient PTSD symptom trajectory, individuals presenting with chronic PTSD trajectories were estimated to experience average pain scores 2.61 points higher (95% CI: 1.71, 3.14). Participants presenting with worsening (ß = 1.42; 95% CI: 0.77, 1.78) and recovering PTSD trajectories (ß = 0.65; 95% CI: 0.09, 1.08) were estimated to experience higher average pain scores than participants with resilient PTSD trajectories. Significant differences in pain interference scores were observed across PTSD trajectories. Receiving RA was associated with improved pain up to two years after injury (ß = -0.31; 95% CI: -0.90, -0.04), however no statistically significant association was detected between RA and PTSD trajectories. CONCLUSIONS: Chronic and worsening PTSD trajectories were associated with greater pain intensity and interference following combat injury even when accounting for receipt of early RA for pain management. These findings underscore the need to jointly assess pain and PTSD symptoms across the trauma care continuum.

Law and Policy as Tools in Healthy People 2030.

Laws and policies are critical determinants of health and well-being. They can encourage positive behaviors and discourage harmful behaviors, and they can enhance or worsen health, health equity, health disparities, and health literacy. Recognizing their contribution to conditions in the environments in which people are born, live, learn, work, play, worship, and age, and people's experiences of these conditions, the US Department of Health and Human Services considered the roles of law and policy throughout its development of Healthy People 2030. Laws and policies often interrelate, but they have different purposes. A law is an established procedure, standard, or system of rules that members of a society must follow. A policy is a decision or set of decisions meant to address a long-term purpose or problem. Healthy People 2030 offers an opportunity for users in diverse sectors and at all levels to use laws and policies to support or inform the initiative's implementation, address health disparities and health inequities, and improve health and well-being in this decade. Introducing new laws and policies or rescinding existing ones to achieve Healthy People 2030 goals offers a chance to rigorously assess outcomes and weigh the balance of good outcomes against unintended consequences.

Beyond Band-Aids for Bullet Holes: Firearm Violence As a Public Health Priority.

OBJECTIVES: To review the public health approach to preventing and treating firearm violence. DATA SOURCES: Peer-reviewed, published scholarship and federal data systems. STUDY SELECTION: English-language, indexed research articles on the epidemiology, risk, prevention, and consequences of firearm violence. DATA EXTRACTION: This narrative review includes findings related to the epidemiology and impact of firearm violence, focusing on short- and long-term outcomes. Evidence supporting interventions at the individual, agent, and environmental level to reduce firearm-related harm was examined. DATA SYNTHESIS: Firearm violence is a major public health challenge in the Unites States. The consequences of firearm violence reach beyond the nearly 40,000 firearm-related deaths and 90,000 firearm-related injuries each year. Firearm violence, including self-harm, assault, and unintentional injury, affects the health of individuals, families, communities, and health systems. Data sources remain inadequate, however, to fully capture these impacts. Treating firearm violence as a disease and taking a public health approach to prevention and treatment is key to reducing the harms of firearm violence. Using a public health framework not only recognizes the physical and mental consequences of firearm violence but also focuses our attention on underlying causes and on innovative, multi-level interventions to reduce the harms of firearm violence. CONCLUSIONS: The public health approach positions clinicians to change the conversation from political diatribe of pro-gun and anti-gun to systematically reducing injury and death. To achieve comparable success, we must design, test, and implement effective interventions at the environmental, policy, technological, and individual levels to prevent firearm violence. We must collect robust data on firearm violence and its consequences. And we must reckon with the conditions of inequality and disadvantage that feed violence through all means.

Pathways to Help-Seeking Among Black Male Trauma Survivors: A Fuzzy Set Qualitative Comparative Analysis.

Many Black men suffer symptoms of traumatic stress in the aftermath of traumatic injury, and they also often carry social concerns, including experiences of discrimination and stigma, and a lack of financial resources. The objective of the present study was to understand how traumatic symptoms and social factors combine in complex ways toward the outcome of psychological help-seeking. We analyzed qualitative and quantitative data from 32 injured Black men admitted to a Level 1 trauma center. Qualitative interviews explored their attitudes toward seeking professional psychological help. We analyzed quantitative data, collected using validated instruments, on posttraumatic stress and depression symptoms, financial worry, and discrimination/stigma. Fuzzy set qualitative comparative analysis (fsQCA) was conducted by calibrating each condition to fuzzy set membership scores based on our knowledge of the causal conditions and the cases. We then constructed truth tables for QCA analysis using fsQCA software. Three causal pathways for psychological help-seeking were identified: Two pathways showed that severe trauma symptoms in the absence of financial worry were sufficient for seeking help, whereas the third showed that financial worry and discrimination in the absence of trauma symptoms were sufficient for help-seeking. We identified two causal pathways for negated help-seeking, in which low posttraumatic symptom severity and low levels of discrimination or financial worry were sufficient for not seeking psychological help. The QCA analysis revealed multiple pathways for psychological help-seeking among Black men who suffer trauma. These findings highlight the need for further research to understand complex pathways toward psychological help-seeking in this population.

'Sharing things with people that I don't even know': help-seeking for psychological symptoms in injured Black men in Philadelphia.

Objectives: Psychological distress is common in survivors of traumatic injury, yet across United States' trauma systems, it is rare that standard injury care integrates psychological evaluation and professional mental healthcare. The purpose of this study was to explore help-seeking for psychological symptoms in injured Black men living in Philadelphia. Design: A subset of a cohort of 551 injured Black men admitted to a Trauma Center in Philadelphia participated in qualitative interviews that explored their perceptions of psychological symptoms after injury and the factors that guided their decision to seek professional mental health help. Data from 32 participants were analyzed for narrative and thematic content. Results: Three overarching themes emerged: (1) facilitators of help-seeking, (2) barriers to help-seeking, and (3) factors underlying the decision not to consider professional help. Five participants felt that their injury-related psychological distress was severe enough to merit professional help despite any perceived barriers. Seventeen participants identified systemic and interpersonal obstacles to professional help that prevented them from seeking this kind of care. These included: financial constraints, limited access to mental healthcare services, and fear of the judgments of mental healthcare professionals. Ten participants would not consider professional help; these men perceived a lack of need and sufficiency in their existing social support networks. Conclusions: Research is needed to inform or identify interventions that diminish the impact of barriers to care, and identify from whom, where, and how professional mental health help might be more effectively offered to injured Black men in recovery environments like Philadelphia.

Mixed studies review of factors influencing receipt of pain treatment by injured black patients.

AIM: To explore the factors that influence provider pain treatment decision-making and the receipt of pain management by injured Black patients in the United States. DESIGN: We completed a systematic mixed studies review using a results-based convergent synthesis design. DATA SOURCES: PubMed, SCOPUS and CINAHL were searched for articles published between 2007-2017 using the search terms 'African American', 'Black American', 'race', 'pain treatment', 'pain management' and 'analgesia'. Twenty studies were included in this review. REVIEW METHOD: A search of databases and hand-searching identified peer-reviewed published papers. The Mixed Method Appraisal Tool was used to appraise the studies. RESULTS: The results indicate that healthcare provider characteristics, racial myths about pain sensitization and assumed criminality all impact provider treatment decision-making and the receipt of pain treatment by injured Black patients. IMPACT: This review addresses racial disparities in pain management by focusing on the factors that impact the receipt of pain treatment by injured Black patients. The findings will have an impact on providers who prescribe pain treatment and on the patients they treat. These findings suggest that assumed criminality of certain patients can negatively impact care, which is a type of bias not frequently explored or discussed in health disparities research. This review will help inform further research in healthcare disparities and prompt providers to examine their assumptions about the patients for whom they care. CONCLUSION: These results provide important areas for further study, including how assumed criminality of certain patients can have a negative impact on care.

Opioid use disorder research and the Council for the Advancement of Nursing Science priority areas.

BACKGROUND: Chronic diseases, such as opioid use disorder (OUD) require a multifaceted scientific approach to address their evolving complexity. The Council for the Advancement of Nursing Science's (Council) four nursing science priority areas (precision health; global health, determinants of health, and big data/data analytics) were established to provide a framework to address current complex health problems. PURPOSE: To examine OUD research through the nursing science priority areas and evaluate the appropriateness of the priority areas as a framework for research on complex health conditions. METHOD: OUD was used as an exemplar to explore the relevance of the nursing science priorities for future research. FINDINGS: Research in the four priority areas is advancing knowledge in OUD identification, prevention, and treatment. Intersection of OUD research population focus and methodological approach was identified among the priority areas. DISCUSSION: The Council priorities provide a relevant framework for nurse scientists to address complex health problems like OUD.

Firearm Violence: A Global Priority for Nursing Science.

PURPOSE: This purpose of this article is to frame firearm violence as a health and public health problem, to illustrate the magnitude of the problem, to examine factors that increase the risk to be injured by a firearm, or conversely, that confer protection, and to identify relevant priority areas for nursing science. ORGANIZING CONSTRUCT: Firearm violence results in physical and psychological injuries and is a global health priority. Firearm violence is categorized as intentional (interpersonal and self-inflicted) and unintentional (interpersonal and self-inflicted) and accounts for an estimated 196,000 to 220,000 nonconflict deaths annually. METHODS: We reviewed the theoretical and scientific literature to analyze the magnitude and geographic distribution of firearm violence, the factors associated with firearm injury, the consequences of firearm violence, and areas where nursing science can make an impact on prevention, outcomes, and recovery. FINDINGS: Firearm violence is a significant public health problem that affects the health of individuals, families, and communities. The burdens and contributors to firearm violence vary worldwide, making it important to understand the local context of this global phenomenon. Relevant areas of inquiry span primary prevention focusing on individual and environmental risk factors; and focus on managing the physical and psychological consequences postinjury; and mitigating long-term consequences of firearm violence. CONCLUSIONS: Reducing the global burden of firearm violence and improving the health and safety of individuals, families, and communities provide compelling reasons to integrate this area into nursing science. CLINICAL RELEVANCE: The goals of nursing are to keep people healthy and safe and to help return those injured to their optimal levels of health and well-being. Understanding the factors that come together to injure people with a firearm in various physical, social, economic, and cultural environments positions nurses to both extend the dialogue beyond pro-gun versus anti-gun and to design and carry out rigorous studies to reduce firearm violence.

Ways of knowing in precision health.

Precision health can provide an avenue to bridge and integrate ways of knowing for research and practice. Nurse scientists have a long-standing interest in using multiple sources of information to address research questions of significance to the profession and discipline of nursing, which can lead to much needed contributions to precision health care. In this paper, nursing scientists discuss emerging research methods including omics, electronic sensors, and geospatial data, and mixed methods that further develop nursing science and contribute to precision health initiatives. The authors provide exemplars of the types of knowledge and ways of knowing that, using these and other advanced data and analytic strategies, may advance precision health within the context of nursing science.

Adult Connection in Assault Injury Prevention among Male Youth in Low-Resource Urban Environments.

Strengths-based strategies to reduce youth violence in low-resource urban communities are urgently needed. Supportive adolescent-adult relationships may confer protection, but studies have been limited by self-reported composite outcomes. We conducted a population-based case-control study among 10- to 24-year-old males in low-resource neighborhoods to examine associations between supportive adult connection and severe assault injury. Cases were victims of gunshot assault injury (n = 143) and non-gun assault injury (n = 206) from two level I trauma centers. Age- and race-matched controls (n = 283) were recruited using random digit dial from the same catchment. Adolescent-adult connections were defined by: (1) brief survey questions and (2) detailed family genograms. Analysis used conditional logistic regression. There were no significant associations between positive adult connection, as defined by brief survey questions, and either gunshot or non-gun assault injury among adolescents with high prior violence involvement (GSW OR = 2.46, 95% CI 0.81-7.49; non-gun OR = 1.59, 95% CI 0.54-4.67) or low prior violence involvement (GSW OR = 0.92, 95% CI 0.34-2.44; non-gun OR = 1.96, 95% CI 0.73-5.28). In contrast, among adolescents with high levels of prior violence involvement, reporting at least one supportive adult family member in the family genogram was associated with higher odds of gunshot assault injury (OR = 4.01, 95% CI 1.36-11.80) and non-gun assault injury (OR = 4.22, 95% CI 1.48-12.04). We were thus unable to demonstrate that positive adult connections protected adolescent males from severe assault injury in this highly under-resourced environment. However, at the time of injury, assault-injured adolescents, particularly those with high prior violence involvement, reported high levels of family support. The post-injury period may provide opportunities to intervene to enhance and leverage family connections to explore how to better safeguard adolescents.

Neighbourhood social trust and youth perceptions of safety during daily activities.

Exposure to adverse neighbourhood conditions can negatively impact adolescent well-being and perceived safety. However, the impact of neighbourhood social trust on perceived safety is largely unknown. We studied 139 adolescent men to investigate how their perceptions of safety varied as a function of social trust levels in the neighbourhoods they traversed; neighbourhoods that were not necessarily their own. Adolescents mapped their minute-by-minute activities over a recent day and rated their perceived safety on a 10-point scale during in-person interviews. Neighbourhood social trust was measured via a citywide random sample survey. Mixed effects regression showed that, compared with their safety perceptions when in areas of low social trust, older adolescents were 73% more likely to feel unsafe when in areas of medium social trust, and 89% more likely to feel unsafe when in areas of high social trust. Inverse relationships between neighbourhood social trust and adolescents' perceived safety highlight the complex interplay between youth, environmental contexts and safety.

Complexity of the Relationships of Pain, Posttraumatic Stress, and Depression in Combat-Injured Populations: An Integrative Review to Inform Evidence-Based Practice.

BACKGROUND: Understanding the complex interrelationships between combat injuries, physical health, and mental health symptoms is critical to addressing the healthcare needs of wounded military personnel and veterans. The relationship between injury characteristics, pain, posttraumatic stress disorder (PTSD), and depression among combat-injured military personnel is unique to modern conflicts and understudied in the nursing literature. AIM: This integrative review synthesizes clinical presentations and relationships of combat injury, PTSD, depression, and pain in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) United States military service members and veterans. METHODS: A literature search was conducted using relative key terms across databases to identify peer-reviewed publications between 2001 and 2016 that examined health outcomes of combat-injured persons in OEF and OIF. The quality of evidence was evaluated and results synthesized to examine the association of combat injury as a risk factor for PTSD, the relationship of PTSD and depression pre- and postinjury, and pain management throughout care. RESULTS: Twenty-two articles were included in this review. Greater injury and pain severity poses risks for developing PTSD following combat injury, while early symptom management lessens risks for PTSD. Depression appears to be both a contributing risk factor to postinjury PTSD, as well as a comorbidity. LINKING EVIDENCE TO ACTION: Findings demonstrate a compelling need for improvements in standardized assessment of pain and mental health symptoms across transitions in care. This integrative review informs nurse researchers and providers of the clinical characteristics of pain, PTSD, and depression following combat injury and offers implications for future research promoting optimal surveillance of symptoms.

Trauma Providers' Knowledge, Views, and Practice of Trauma-Informed Care.

Trauma-informed interventions have been implemented in various settings, but trauma-informed care (TIC) has not been widely incorporated into the treatment of adult patients with traumatic injuries. The purpose of this study was to examine health care provider knowledge, attitudes, practices, competence, and perceived barriers to implementation of TIC. This cross-sectional study used an anonymous web-based survey to assess attitudes, knowledge, perceived competence, and practice of TIC among trauma providers from an urban academic medical center with a regional resource trauma center. Providers (nurses, physicians, therapists [physical, occupational, respiratory]) working in trauma resuscitation, trauma critical care, and trauma care units were recruited. Descriptive statistics summarized knowledge, attitudes, practice, competence, and perceived barriers to TIC and logistic regression analyses examined factors predicting the use of TIC in practice. Of 147 participants, the majority were nurses (65%), followed by therapists (18%) and physicians (17%), with a median 3 years of experience; 75% answered the knowledge items correctly and 89% held favorable opinions about TIC. Nineteen percent rated themselves as less than "somewhat competent." All participants rated the following as significant barriers to providing basic TIC: time constraints, need of training, confusing information about TIC, and worry about retraumatizing patients. Self-rated competence was the most consistent predictor of providers' reported use of specific TIC practices. Despite some variability, providers were generally knowledgeable and held favorable views toward incorporating TIC into their practice. TIC training for trauma providers is needed and should aim to build providers' perceived competence in providing TIC.

The Association Between Urban Tree Cover and Gun Assault: A Case-Control and Case-Crossover Study.

Green space and vegetation may play a protective role against urban violence. We investigated whether being near urban tree cover during outdoor activities was related to being assaulted with a gun. We conducted geographic information systems-assisted interviews with boys and men aged 10-24 years in Philadelphia, Pennsylvania, including 135 patients who had been shot with a firearm and 274 community controls, during 2008-2011. Each subject reported a step-by-step mapped account of where and with whom they traveled over a full day from waking until being assaulted or going to bed. Geocoded path points were overlaid on mapped layers representing tree locations and place-specific characteristics. Conditional logistic regressions were used to compare case subjects versus controls (case-control) and case subjects at the time of injury versus times earlier that day (case-crossover). When comparing cases at the time of assault to controls matched at the same time of day, being under tree cover was inversely associated with gunshot assault (odds ratio (OR) = 0.70, 95% confidence interval (CI): 0.55, 0.88), especially in low-income areas (OR = 0.69, 95% CI: 0.54, 0.87). Case-crossover models confirmed this inverse association overall (OR = 0.55, 95% CI: 0.34, 0.89) and in low-income areas (OR = 0.54, 95% CI: 0.33, 0.88). Urban greening and tree cover may hold promise as proactive strategies to decrease urban violence.
