Cognitive trajectories after surgery: Guideline hints for assessment and treatment.

Elderly patients who undergo major surgery (not-neurosurgical) under general anaesthesia frequently complain about cognitive difficulties, especially during the first weeks after surgical "trauma". Although recovery usually occurs within a month, about one out of four patients develops full-blown postoperative Neurocognitive disorders (NCD) which compromise quality of life or daily autonomy. Mild/Major NCD affect approximately 10% of patients from three months to one year after major surgery. Neuroinflammation has emerged to have a critical role in the postoperative NCDs pathogenesis, through microglial activation and the release of pro-inflammatory cytokines which increase blood-brain-barrier permeability, enhance movement of leukocytes into the central nervous system (CNS) and favour the neuronal damage. Moreover, pre-existing Mild Cognitive Impairment, alcohol or drugs consumption, depression and other factors, together with several intraoperative and post-operative sequelae, can exacerbate the severity and duration of NCDs. In this context it is crucial rely on current progresses in serum and CSF biomarker analysis to frame neuroinflammation levels, along with establishing standard protocol for neuropsychological assessment (with specific set of tools) and to apply cognitive training or neuromodulation techniques to reduce the incidence of postoperative NCDs when required. It is recommended to identify those patients who would need such preventive intervention early, by including them in pre-operative and post-operative comprehensive evaluation and prevent the development of a full-blown dementia after surgery. This contribution reports all the recent progresses in the NCDs diagnostic classification, pathogenesis discoveries and possible treatments, with the aim to systematize current evidences and provide guidelines for multidisciplinary care.

Characterising a syndemic among black women at risk for HIV: the role of sociostructural inequity and adverse childhood experiences.

Objectives Black women disproportionately experience STIs (including HIV/AIDS), gender-based violence, substance misuse and mental health conditions. Addressing a gap in syndemic research, we characterised comorbidity overlap within the context of sociostructural inequities and adverse childhood experiences (ACEs) among black women in Baltimore, Maryland. Methods Between 2015 and 2018, black women (n=305) were recruited from STI clinics in Baltimore, Maryland. Among those with complete survey data (n=230), we conducted a latent class analysis to differentiate women based on their profile of the following syndemic comorbidities: STIs, adult sexual victimisation, substance misuse and mental health disorders. We then examined the association between ACEs and syndemic latent class membership. Results Thirty-three percent of women experienced three to nine ACEs before age 18 years, and 44% reported four to six comorbidities. The two-class latent class solution demonstrated the best fit model, and women were categorised in either class 1 (past-year STI; 59%) or class 2 (syndemic comorbidities; 41%). Women in class 2 were more likely to report unstable housing (10% vs 3%) and identify as bisexual/gay (22% vs 10%) than women in class 1. ACEs were significantly associated with an increased likelihood of class 2 membership. Conclusions This study reinforces the importance of screening for ACEs and offering trauma-informed, integrated care for black women with syndemic comorbidities. It also highlights the critical nature of tailoring interventions to improve sociostructural equity, preventing and reducing syndemic development.

An examination of the association between forced sex history and reproductive coercion experiences among Black women attending STD clinics in Baltimore, MD, USA.

BACKGROUND: Reproductive coercion victimization (RCV) is a significant public health issue that negatively affects women's sexual and reproductive health outcomes. Less is known about reproductive coercion perpetration (RCP). Few studies have examined these phenomena among representative samples of Black women. METHODS: Retrospective data of women (n = 298) attending STD clinics in Baltimore, MD were analyzed. We calculated lifetime and 12-month prevalence reports of reproductive coercion, and reported values stratified by forced sex history. Binomial logistic regression models were used to examine the association between forced sex history and RCV, accounting for other types of violence typologies. RESULTS: Lifetime and past 12-month RCV and RCP prevalence were higher among women with forced sex experiences than their counterparts (Lifetime RCV: 46.9% versus 17.5%; past 12-month RCV: 19.4% versus 8.5%. Lifetime RCP: 24.5% versus 17%; past 12-month RCP: 13.3% versus 10.5%). Adjusted models, lifetime reproductive coercion: Women reporting forced sex had a 3.58 times higher odds of having had experienced RCV compared to women not reporting forced sex (AOR 3.58; 95% CI 2.00, 6.46). Women reporting forced sex had a 3.66 times higher odds of having ever experienced pregnancy coercion compared to their counterparts (AOR 3.66; 95% CI 1.93, 7.03) and 4.30 times higher odds of having ever experienced condom manipulation (AOR 4.30; 95% CI 2.15, 8.86). Adjusted models, past 12-month reproductive coercion: Women reporting forced sex had a 2.72 times higher odds of having had experienced past 12-month RCV compared to women not reporting forced sex (AOR 2.72; 95% CI 1.27, 5.91). Women reporting forced sex had a 3.25 times higher odds of having experienced past 12-month pregnancy coercion compared to their counterparts (AOR 3.25; 95% CI 1.38, 7.83) and 3.41 times higher odds of having experienced past 12-month condom manipulation (AOR 3.41; 95% CI 1.14, 10.98). CONCLUSIONS: Participants in our study reported high rates of RCV. Our novel exploration revealed significantly high rates of co-occurring forced sex experiences and RCV and initial prevalence report of RCP. Agencies have a unique opportunity to intervene by implementing screening protocols and referrals for supportive services. These findings may inform future intervention research efforts aimed at improving reproductive health outcomes among Black women.

Made in the shade: A qualitative study of factors impacting shade provision at outdoor public parks.

Shade provides a variety of public health benefits; however, outdoor recreation sites often have limited shade. We conducted semi-structured interviews (n = 13) with shade stakeholders (i.e. individuals with a professional role involving shade design or provision) to gain in-depth understanding of the factors impacting shade provision at public parks. Interview transcripts were analyzed using inductive thematic analysis. Five main themes emerged: (1) attitudes toward shade at parks; (2) designing shade at parks; (3) advantages and disadvantages of natural and built shade; (4) barriers to shade at parks; and, (5) approaches to reduce shade barriers. Shade stakeholders indicated shade is important and necessary and they strive to design shade in park spaces with park user patterns in mind. However, barriers including competing interests, budget, space constraints, and maintenance and operational concerns can limit their ability to do so. Future research should determine strategies to overcome these barriers.

Residential Greenness Positively Associated with the Cortisol to DHEA Ratio among Urban-Dwelling African American Women at Risk for HIV.

As ecosystems that support human health, societies, and civilization change in the era of the Anthropocene, individuals with disproportionate balance of salivary hormones may be at greatest risk of morbidity and mortality. Vulnerable communities, in particular, are overburdened by inequities in features of built environments linked to health disparities. This study examined the cross-sectional association of greenness in the built environment with the ratio of cortisol to dehydroepiandrosterone (DHEA) in an urban-dwelling high-risk community sample of African American women (n = 84, age 18-44 years). Saliva samples, collected across 2 consecutive days, were assayed for cortisol and DHEA. Controlling for sexual violence, perceived stress, education, and income, as well as crime, traffic density, and vacant properties, we observed a significant positive cross-sectional association between greenness and the cortisol to DHEA ratio, (ß = 7·5, 95% CI: 0.89, 14.19). The findings highlight environmental influence on stress response at waking when there is the greatest individual variation. Implications for advancing our understanding of the waking ratio of cortisol to DHEA as a potential marker of physiological resilience are discussed.

Polyvictimization and Substance Use Among Sexual Minority Cisgender Women.

BACKGROUND: Violent victimization and substance use are higher among sexual minority cisgender women (SMCW) than heterosexual cisgender women. Unknown, however, is how polyvictimization-experiencing multiple types of violent victimization-affects substance use among SMCW. Purpose/Objectives: This study explores the relationship between polyvictimization and substance use among a small sample of SMCW. Methods: An exploratory secondary data analysis was conducted on data from a convenience sample of 115 SMCW currently in relationships (70.4% lesbian, 73.9% non-Hispanic white) via a cross-sectional survey. Lifetime physical, sexual, and crime-related violent victimization were measured via the Trauma History Questionnaire. Past-year substance use was measured via the Drug Abuse Screening Test (DAST-10). Mann-Whitney U testing and linear regression modeling were used to examine differences in substance use by victimization status (victimized/non-victimized) and the association between polyvictimization and substance use. Results: Lifetime prevalence of violent victimization was high with 60.9% of the sample reporting at least one type of victimization: 10.4% experienced physical, 22.6% experienced sexual, and 22.6% experienced crime-related violent victimization. Substance use was significantly greater for victimized participants than non-victimized participants. Modeling showed that as violent victimization increased by one unit, substance use scores increased by .30 units. Conclusion/Importance: Preliminary evidence suggests that increase in violent victimization was associated with increased substance use among SMCW. Findings indicate a need for additional confirmatory research with more representative samples and longitudinal data. Behavioral health practitioners are urged to consider the implications of these findings and assess for past cumulative violence and current risk of substance use disorder, to appropriately facilitate treatment planning.

Physiological Changes from Violence-Induced Stress and Trauma Enhance HIV Susceptibility Among Women.

PURPOSE OF REVIEW: This theoretical review identifies physiological mechanisms by which violence against women (VAW) may increase women's susceptibility to HIV through trauma, stress, and immune dysfunction. RECENT FINDINGS: Research documents systemic and local immune responses are related to stress and trauma from abuse across the life course (i.e., childhood, IPV, adulthood re-victimization). Findings are interpreted within a theoretical framework grounded in the Social Stress Theory and the concept of toxic stress, and highlight the current state of the science connecting: (1) VAW to the physiological stress response and immune dysfunction, and (2) the physiological stress response and inflammation to HIV susceptibility and infection in the female reproductive tract. Despite a dearth of research in human subjects, evidence suggests that VAW plays a significant role in creating a physiological environment conducive to HIV infection. We conclude with a discussion of promising future steps for this line of research.

Impact of legislation on youth indoor tanning behaviour: A systematic review.

Jurisdictions around the world have implemented indoor tanning legislations, which aim to protect all individuals, especially youth, from dangers of artificial ultraviolet radiation exposure. The objective of this study was to conduct a systematic review to synthesize the available peer-reviewed literature to determine whether indoor tanning legislation has impacted the prevalence of youth indoor tanning. Following PRISMA guidelines, six databases were searched in 2016. Reference lists from relevant articles were also searched. An updated literature search was conducted in 2018. Each article was critically appraised using a merged checklist created from two previously validated checklists. All articles meeting the inclusion criteria were retained after appraisal. Seven studies, all conducted in the U.S., met the inclusion criteria. All studies used an observational, cross-sectional design. There were small absolute decreases in youth indoor tanning prevalence after legislation vs before (n = 3, mean = 3% decrease, range = 1%-6% decrease). Prevalence of youth indoor tanning was significantly lower in states with indoor tanning legislation vs states without legislation (n = 4, mean = 5% lower, range = 1%-18% lower). Prevalence of youth indoor tanning was lower in states with longer standing indoor tanning legislation vs states with more recently implemented legislation (n = 2, mean = 9% lower, range = 2%-20% lower). Indoor tanning legislation is generally associated with lower indoor tanning prevalence among youth. The small percent differences equate to millions of youth at the population level. Longer time lapses from legislation implementation to evaluation, coupled with greater enforcement, compliance, legislative stringency, and public education may result in even more pronounced declines in youth indoor tanning prevalence.

Examining Trauma and Readiness to Change among Women in a Community Re-Entry Program.

BACKGROUND: Posttraumatic stress disorder (PTSD) and co-occurring substance use disorders (SUDs) are common among women who are incarcerated. OBJECTIVE: The purpose of this study was to examine the relationship between trauma and readiness to change substance use behaviors. METHODS: This study used data from 103 participants enrolled in a residential re-entry program for women with SUDs and trauma history. Women reporting clinically elevated Trauma Symptom Inventory (TSI) subscale scores were compared to those without elevated scores on the University of Rhode Island Change Assessment (URICA) readiness to change instrument. Primary analyses included t-tests and ANCOVA to control for age and ethnicity. RESULTS: In general, women with clinically elevated trauma scores also reported greater readiness to change. The analyses revealed significant differences on the URICA Readiness to Change scores between women who had elevated Defensive Avoidance and Impaired Self-Reference according to the TSI. Results approached significance for women who had elevated TSI subscale scores for Sexual Concerns and Dissociation. CONCLUSIONS: These results point to a need to further understand links between trauma and readiness to change, particularly, the role of posttraumatic growth and psychological distress. This study has implications for social workers and clinicians delivering evidence-based treatment. Women who had high trauma symptoms were more willing to address change. Findings also suggest a need to tailor interventions to include motivational components that are also trauma-informed.

Overview of the Robert Wood Johnson Foundation Nurse Faculty Scholars program.

BACKGROUND: The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing faculty shortage and thereby decrease the nursing shortage. PURPOSE: The purpose of the study was to describe the program development, implementation, and ongoing outcome evaluation. METHODS: Data on scholarly productivity, impact of research, research funding, and leadership positions were compiled, including an h-index (impact of publications) comparison with a comparison group of other interdisciplinary faculty at the same institutions of the 90 current and alumni scholars. DISCUSSION: There is evidence of the achievements of the individual scholars; however, the effect of the synergy of the multiple components of the program is difficult to capture in traditional evaluation strategies. CONCLUSIONS: The sense of possibility and responsibility (to the profession, to improving the health of all Americans, and to one's school of nursing and university) was a significant outcome of the program. Lessons learned from the program are important for the leadership development and retention of nursing faculty.

Childhood Maltreatment and Child Protective Services Involvement Among the Commercially Sexually Exploited: A Comparison of Women Who Enter as Juveniles or as Adults.

A risk for commercial sexual exploitation is childhood maltreatment. It's unknown whether juveniles in commercial sexual exploitation experience more childhood maltreatment than adults or how involved child protective services is in investigating maltreatment, a focus of this study. Women (N = 96) who sold sex commercially completed a cross-sectional questionnaire. Descriptive statistics, t tests, chi-squares, and odds ratios were used to examine differences in background, childhood maltreatment, and child protective services involvement by juvenile or adult entry. Although 93% of participants experienced child maltreatment, juveniles had increased odds of parent/caregiver sexual abuse, being left alone, being kicked out, and running away from a parent/caregiver. There were no differences in cumulative childhood maltreatment resulting in an investigation or removal, indicating that juveniles not investigated or removed by child protective services had as much childhood maltreatment as juveniles who were investigated or removed by child protective services. Results highlight the need for child welfare staff to recognize childhood maltreatment as risks for commercial sexual exploitation.

Exhaust All Measures: Ethical Issues in Pediatric End-of-Life Care.

The death of a child may have a profound impact on parents, family members, and health care providers who provided care for the child. Unique challenges are faced by parents of seriously ill children as they must serve as the legal authority for health care decisions of children under age 18, although the child's wishes must also be considered. Social workers must balance core social work values, bioethical values, and psychosocial issues presented by such situations. While studies have been conducted with physicians and nurses regarding ethical issues in pediatric end-of-life care settings, little is known about how social workers experience these conflicts. This article utilizes two vignettes to illustrate potential ethical issues in this setting and applies the National Association of Social Workers Standards for Palliative and End of Life Care (NASW, 2004 ) to explore options for their resolution. These vignettes provide descriptions of possible reactions in this setting and can be used as a basis for further exploration of ethics in pediatric end-of-life care from a social work perspective.

Do crosslinking and vitamin E stabilization influence microbial adhesions on UHMWPE-based biomaterials?

BACKGROUND: Microorganism adhesion on polyethylene for total joint arthroplasty is a concern. Many studies have focused on vitamin E-stabilized ultrahigh-molecular-weight polyethylene (UHMWPE), whereas first-generation, highly crosslinked UHMWPE, which is the most commonly used in clinical practice, has been scarcely evaluated. QUESTIONS/PURPOSES: We aimed (1) to compare the adherence of Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, and Candida albicans with virgin (untreated) UHMWPE (PE) and crosslinked UHMWPE (XLPE); (2) to correlate the results with the biomaterial surface properties; and (3) to determine whether the decreased adhesion on vitamin E-stabilized UHMWPE (VE-PE) previously recorded for bacteria can also be confirmed for C albicans. METHODS: Microbial adhesion of biofilm-producing American Type Culture Collection (ATCC) and clinical strains on XLPE and VE-PE were compared with PE at 3, 7, 24, and 48 hours of incubation and quantified, as colony forming units (CFU)/mL, using a sonication protocol. Sample surfaces were characterized by scanning electron microscopy, roughness and contact angle measurements, attenuated total reflection-Fourier transform infrared spectroscopy, and x-ray photoelectron spectroscopy (XPS) to reveal qualitative differences in surface composition and topography that could influence the microbial adhesion. The results were analyzed by descriptive statistics and tested by unpaired t-tests. RESULTS: All microorganisms, both ATCC and clinical strains, showed lower adhesion (p < 0.05) on XLPE with adhesion percentages ranging from 18% to 25%, compared with PE with adhesion percentages ranging from 51% to 55%, after 48 hours. Only the ATCC S epidermidis showed a reduced adhesion profile even at 3 hours (adhesion ratio of 14% on XLPE versus 50% on PE) and 24 hours (19% on XLPE versus 55% on PE) of incubation. ATCC and clinical C albicans were less adherent to XLPE than to PE (p < 0.05) showing even at the earlier incubation time points adhesion values always of 10(3) CFU/mL and 10(4) CFU/mL, respectively. Roughness and contact angle were 0.8 ± 0.2 µm and 92° ± 3°, respectively, with no differences among samples. Qualitative differences in the surface chemical composition were revealed by XPS only. A confirmation of the decreased adhesion on VE-PE respect to PE was also registered here for C albicans strains (p < 0.05). CONCLUSIONS: Vitamin E stabilization and crosslinking of UHMWPE are capable of reducing microbial adhesion. Further studies are needed to fully elucidate the mechanisms of modulation of microbial adhesion to medical-grade UHMWPE. CLINICAL RELEVANCE: Our results suggest that VE-PE and XLPE may have an added benefit of being more resistant to bacterial adhesion, even fungal strains.

Linguistic acculturation and perceptions of quality, access, and discrimination in health care among Latinos in the United States.

This study examined the relationship between acculturation and Latinos' perceptions of health care treatment quality, discrimination, and access to health information. The results of this study indicated that participants who had lower levels of acculturation perceived: 1) greater discrimination in health care treatment; 2) a lower quality of health care treatment; 3) less confidence filling out health related forms; and 4) greater challenges understanding written information about their medical conditions. Participants who identified as immigrants also perceived that their poor quality of medical care was due to their inability to pay and to their race/ethnicity.

Beyond Victim Identification: A Practitioner's Guide to Designing a Youth Anti-Sex Trafficking Advocacy Program.

Thousands of youth are sexually trafficked each year in the United States. In order to address this concern, anti-trafficking advocates often emphasize the importance of uniform screening protocols to assist with the identification of survivors. Unfortunately, an oft-overlooked component of sex trafficking identification is what to do once a victim has been identified, and how to best meet survivors' complex needs. In this article, the authors provide social work practitioners and other advocates with best practice guidelines for how to design and evaluate anti-sex trafficking advocacy programs for children and youth. These guidelines include considerations related to direct services with clients, community partnerships, and organizational capacity, as well as recommendations for how to begin and then evaluate programming. Regardless of the form selected for the program, all anti-sex trafficking programs should be designed to provide effective, client-centered follow-up and advocacy once a positive identification is made in the community. The recommendations included in this paper are based upon extant literature, the authors' practice experience with survivors, and insights from anti-sex trafficking program evaluations.

Coping self-efficacy and social support as predictors of adolescent sex trafficking exit: Results of a secondary analysis.

INTRODUCTION: Social work case management services are increasingly available to youth who want to exit commercial sexual exploitation (CSE). However, few empirical studies investigate the efficacy of such services, particularly whether these services promote an exit from CSE. Guided by ecological systems theory and the Intentions to Exit Prostitution (IEP) model, this study investigates the efficacy of social work case management services for youth CSE survivors. METHODS: Youth survivors of CSE (n = 95) participated in a one-group, quasi-experimental double pre/posttest design study. Measures included the Multidimensional Scale of Perceived Social Support (MSPSS), Coping Self-Efficacy Scale (Cop-SE), and a modified version of the University of Rhode Island Change Assessment (URICA) surveys at zero- and six-months following study commencement. The research team also collected demographic and victimization data, the number and type of social work case management services received, and goal plan data. Analyses included repeated measures tests and linear and multinomial logistic regressions to determine if doses of social work case management are predictive of the positive short-term outcomes that are linked to increased readiness to exit CSE. RESULTS: Youth CSE survivors experienced upward trends in perceived social support and coping self-efficacy scores between zero- and six-months following study commencement. Linear and logistic regressions demonstrated that variables like months of service time, trafficking classification, goal counts, race, and age can predict outcomes like survivor social support, coping self-efficacy, and intention to change behaviors that can lead to revictimization. IMPLICATIONS: Results suggest social work case management services that improve coping self-efficacy and perceived social support can lead to cognitive changes that promote an exit from CSE. Practitioners should target services that adhere to dimensions of the IEP as these improvements are likely to support positive outcomes for youth survivors of CSE.

Discrimination, resilience, and HIV testing frequency among black women seeking services from STD clinics.

RATIONALE: In the United States, Black women are disproportionately affected by HIV, accounting for most new HIV infections diagnosed among women. Socio-structural barriers to HIV testing include stigma and discrimination but may be mitigated by resilience. OBJECTIVE: We aimed to examine the effect of discrimination and resilience on HIV testing behaviors among Black women. METHODS: Between 2016 and 2018, we conducted The ESSENCE Project, a retrospective cohort study on the role of physiological and environmental factors on the association between sexual assault and HIV risk among Black women in Baltimore, Maryland, USA. Black women aged 18-44 were recruited from public health STD clinics and completed an audio-computer-assisted self-interview survey. Hierarchical multiple negative binomial regression models were used to examine the associations of everyday discrimination (subtle and overt) and resilience on HIV testing frequency; resilience and its subscales (relational maintenance, personal fortitude, positive coping, independence and insight) were also examined as moderators. RESULTS: Among 236 Black women reporting HIV testing history, the median number of lifetime HIV tests was 4 (IQR = 2, 6). Mean everyday discrimination was 2.3 (SD = 1.2). Mean resilience was 5.3 (SD = 0.8). Everyday discrimination and its subscales (overt and subtle) were negatively associated with lifetime HIV testing frequency, while overall resilience was not associated with lifetime HIV testing frequency. Accounting for demographics, overall resilience moderated the association of subtle discrimination and lifetime HIV testing frequency. For the resilience subscales, more specifically: (1) associations of subtle discrimination and HIV testing frequency were significant at the lowest relational maintenance and lowest positive coping resilience; and (2) the association of subtle discrimination and HIV testing frequency was significant at the highest resilience for all four subscales. CONCLUSIONS: These findings highlight the need for provider- and community-level interventions addressing the deleterious effects of everyday discrimination and more specifically subtle everyday discrimination to encourage HIV testing.

Discrimination, Sexual Violence, Depression, Post-traumatic Stress Disorder, and Social Support among Black Women.

BACKGROUND: Black Americans face significant discrimination associated with mental health disorder, which may be exacerbated among sexually victimized people. Social support may buffer that relationship. METHODS: Cross-sectional data from a retrospective cohort study were analyzed to examine if discrimination and sexual victimization overlap to exacerbate symptoms of depression and post-traumatic stress disorder (PTSD) and to determine the extent to which social support moderated that association among Black women living in Baltimore, Maryland [138 non-abused (no physical/sexual victimization) and 98 abused (sexually victimized) since age 18]. RESULTS: Symptoms of depression and PTSD were independently associated with discrimination. Multilinear regression showed social support from friends moderated the association between discrimination and depressive symptoms among sexually abused participants only. CONCLUSION: Discrimination may exacerbate symptoms of depression and PTSD more for sexually victimized Black women, but sources of informal social support may attenuate adverse effects of discrimination on depressive symptoms among members of that group.

Risks of Severe Assault and Intimate Partner Homicide among Transgender and Gender Diverse Intimate Partner Violence Survivors: Preliminary Findings from Community Listening Sessions.

Intimate partner violence (IPV) is an epidemic among transgender and gender diverse (TGD) people. However, intimate partner homicide (IPH) among TGD people is under researched. Thus, thematic content analysis was used to describe and examine antecedents of severe assault and IPH among TGD adults who have experienced IPV (N = 13), via community listening sessions. While some themes resembled known severe assault and IPH risks among cisgender women, several themes were unique to TGD people and should be considered when safety planning with TGD individuals or adapting IPV screening tools for this population.

An evaluation of the amount, type and use of shade at public playgrounds in Guelph, Ontario, Canada. / Évaluation de la superficie, du type et de la fréquentation des zones ombragées des terrains de jeu à Guelph (Ontario, Canada).

INTRODUCTION: The provision of shade at outdoor recreation sites such as playgrounds confers a variety of public health benefits. It can prevent overexposure to solar ultraviolet radiation, and, in turn, protect against skin cancer. Further, shade mitigates heat and may promote physical activity. In this study, we evaluate and describe the amount, type and use of shade at public playgrounds. METHODS: Using a modified shade audit tool, shade audits were conducted to visually evaluate shade coverage at 85 city-operated playgrounds in Guelph, Ontario, Canada, in summer 2019. RESULTS: The main play area of most playgrounds (68%) had no shade available. Although the areas surrounding playgrounds had more shade coverage than the main play areas, we also found minimal shade coverage (> 0% to 30%) in this area for many playgrounds (48%). All shade over main play areas was provided by trees (i.e. natural shade). Permanent, built shade structures were observed in the surrounding area of 13% of playgrounds. Shade coverage in the areas surrounding playgrounds was positively correlated with the number of individuals (rs = 0.259; p = 0.017), children (rs = 0.270; p = 0.012), and active individuals (rs = 0.253; p = 0.020) using the surrounding area. This suggests that individuals seek shade at playgrounds and may be more active in shaded areas. CONCLUSION: Children have limited protective shade available to them at playgrounds. Future research is needed to determine how to best increase shade provision and to further explore the impact it has on playground usage, activity levels, temperature and UVR exposure.
