A systematic review of the evidence on the effect of the built and physical environment on mental health

The Meaning of Social Support for Mental Health Service-Users: The Case Managers' Perspective

This study sought to understand the unique types of social support salient to mental health service-users from the perspective of case managers. The sample consisted of case managers working in county mental health agencies in the southwest and west coast. Data was gathered from three focus groups and analyzed using NVivo 10 and Consensual Qualitative Research. Six themes were described including relational support, consistency support, validation and affirmation support, social connection support, day-to-day living support and vocational support. While the social support domains described in this study share conceptual underpinnings with traditional conceptualizations of support, our findings reveal unique types of support from the perspective of case managers. Findings from this study offer an important perspective-case managers-to the extant body of research investigating the meaning of social support for people with lived mental health experiences. Of particular interest is the finding that relational support, affirmative and validation support, and consistency support are salient case manager functions.

The Salford Nature Environments Database (SNED): an open-access database of standardized high-quality pictures from natural environments

The growing interest in harnessing natural environments to enhance mental health, including cognitive functioning and mood, has yielded encouraging results in initial studies. Given that images of nature have demonstrated similar benefits, they are frequently employed as proxies for real-world environments. To ensure precision and control, researchers often manipulate images of natural environments. The effectiveness of this approach relies on standardization of imagery, and therefore, inconsistency in methods and stimuli has limited the synthesis of research findings in the area. Responding to these limitations, the current paper introduces the Salford Nature Environments Database (SNED), a standardized database of natural images created to support ongoing research into the benefits of nature exposure. The SNED currently exists as the most comprehensive nature image database available, comprising 500 high-quality, standardized photographs capturing a variety of possible natural environments across the seasons. It also includes normative scores for user-rated (801 participants) characteristics of fascination, refuge and prospect, compatibility, preference, valence, arousal, and approach-avoidance, as well as data on physical properties of the images, specifically luminance, contrast, entropy, CIELAB colour space parameter values, and fractal dimensions. All image ratings and content detail, along with participant details, are freely available online. Researchers are encouraged to use this open-access database in accordance with the specific aims and design of their study. The SNED represents a valuable resource for continued research in areas such as nature-based therapy, social prescribing, and experimental approaches investigating underlying mechanisms that help explain how natural environments improve mental health and wellbeing.

How does the macroenvironment influence brain and behaviour-a review of current status and future perspectives

The environment influences brain and mental health, both detrimentally and beneficially. Existing research has emphasised the individual psychosocial 'microenvironment'. Less attention has been paid to 'macroenvironmental' challenges, including climate change, pollution, urbanicity, and socioeconomic disparity. Notably, the implications of climate and pollution on brain and mental health have only recently gained prominence. With the advent of large-scale big-data cohorts and an increasingly dense mapping of macroenvironmental parameters, we are now in a position to characterise the relation between macroenvironment, brain, and behaviour across different geographic and cultural locations globally. This review synthesises findings from recent epidemiological and neuroimaging studies, aiming to provide a comprehensive overview of the existing evidence between the macroenvironment and the structure and functions of the brain, with a particular emphasis on its implications for mental illness. We discuss putative underlying mechanisms and address the most common exposures of the macroenvironment. Finally, we identify critical areas for future research to enhance our understanding of the aetiology of mental illness and to inform effective interventions for healthier environments and mental health promotion.

The effect of dwelling size on the mental health and quality of life of female caregivers living in informal tiny homes in Hong Kong

BACKGROUND

Although the adverse impact of substandard informal housing has been widely documented, most studies concentrated on developing societies, thereby leaving informal housing in developed regions underexplored. This study examines Hong Kong, where limited dwelling size is a distinctive feature that characterises informal housing, to explore the impact of housing informality on mental health, with a particular focus on dwelling size. It centers on subdivided units (SDUs), which are tiny compartments partitioned from a large domestic quarter, to understand how housing informality and housing size affect the mental well-being of female caregivers, who typically bear the brunt of the housework.

METHODS

In partnership with nongovernment organisations in three SDU-abundant districts, this mixed-methods study conducted a survey on 413 female caregivers aged 18-65 and qualitative research combining ethnographic observations and in-depth interviews on 36 families living in SDUs in Hong Kong between 2021 and 2023. The mental health outcomes and health-related quality of life (HRQoL) of the participants were assessed by using the Depression, Anxiety, and Stress Scale-21 and a EuroQol-5 Dimension-5 Level questionnaire.

RESULTS

Depression, anxiety and stress were prevalent across the female caregivers living in SDUs (12.4%), as well as a significantly lower HRQoL compared with that of the general population (0.882 vs. 0.919). Findings showed that a total floor area smaller than 13.0 m2 was associated with increased likelihood of experiencing anxiety and depression and reduced HRQoL. Cramped living space adversely affected the caregivers' well-being through the 1) physical, 2) relational and 3) personal aspects of home experiences. Negative experiences at home can cause housework burnout, exacerbate family conflicts and lead to feelings of repression and low self-efficacy.

CONCLUSIONS

This study contributes to the understanding of the consequences of housing informality in diverse geographical contexts and illuminates the effect of dwelling size by identifying the mechanisms through which housing size can affect the mental well-being of residents, which may vary depending on their family status. The findings yield important policy implications, including the need to establish a minimum space standard for subdivided residential dwellings and ensure equitable access to community spaces for deprived families.

Neighborhood predictors of suicide and firearm suicide in Detroit, Michigan

BACKGROUND

Suicide is a leading cause of death in the United States with rates increasing over the past two decades. The rate of suicide is higher in rural areas, but a greater number of people in urban areas die by suicide; understanding risk factors for suicide in this context is critically important to public health. Additionally, while many studies have focused on individual-level risk factors, few studies have identified social or structural features associated with suicide or firearm suicide, especially among young people.

METHODS

Study outcomes included total firearm suicide, total youth (age 10-29) firearm suicide, total suicide, and total youth suicide in Detroit, Michigan from 2012 through 2019. The predictors in this study included 58 census-tract level variables characterizing the physical features, residential stability, socioeconomic status, and demographics of neighborhoods in Detroit over the study period. We used random forest, extreme gradient boosting (XGBoost), and generalized linear mixed models to predict the four outcomes.

RESULTS

We found that the tract-level variables used in all three modeling approaches performed poorly at predicting the suicide outcomes, with area under the curve values at times exceeding 0.60 but with extremely low sensitivity (ranging from 0.05 to 0.45). However, the percentage of parcels sold in arms-length transfers in the previous 5 years, the count of vacant lots per square mile, and the percentage of children aged three and older who were enrolled in preschool each demonstrated associations with at least two of the outcomes studied.

CONCLUSIONS

Our findings suggest place-based factors at the tract level do not provide meaningful insight into the risk of suicide or firearm suicide among youth or the general population in Detroit, Michigan. Future practice and study should consider focusing on both larger and smaller areas, including city and individual-level factors. For example, studies might benefit from the use of both neighborhood and individual-level measures and their interactions to improve our understanding of place-based risk factors and suicide risk.

The role of emotion in urban development decision-making: A qualitative exploration of the perspectives of decision-makers

People's feelings about their neighbourhoods are important for health, but they may be undervalued in urban development decision-making. This study explores how decision-makers understand and respond to residents' emotions. Reflexive thematic analysis was conducted on a secondary dataset consisting of 123 interviews with influential professionals in urban development decision-making. We developed three themes and one subtheme: '(mis)understanding residents' emotions', 'neglecting the health impact of positive emotions', 'avoidance of emotion in community engagement' and 'sanitized emotions'. We recommend decision-makers engage directly with residents' emotions during urban development processes to ensure healthier place-making.

Exploring Disparities in Behavioral Health Service Use in the Early Stages of the COVID-19 Pandemic

BACKGROUND

Previous studies examined the impact of the COVID-19 pandemic on mental health, but few studies looked at associations between the pandemic and state-funded behavioral health service utilization. We aimed to examine behavioral health service utilization during the early phase of COVID-19 among individuals with psychiatric disorders (PD), substance use disorders (SUD), and co-occurring disorders (COD).

METHODS

Using the last Adult Needs and Strengths Assessment (ANSA) completed in 2019 and 2020 in a Midwestern state, a column proportion test and Poisson regression model examined the associations of the pandemic year, age, gender, race/ethnicity, diagnostic type, and behavioral health needs.

RESULTS

Between 2019 and 2020, the number of adults newly involved in behavioral health services increased from 11,882 to 17,385. The number of total actionable items (TAI) differed by gender and age group. Adults who were Black or American Indian were more likely to have a significantly higher number of needs that interfered with functioning (β = 0.08; CI [0.06, 0.09]), (β = 0.16; CI [0.08, 0.23]), respectively, than White peers. Individuals with COD showed the highest number of needs (β = 0.27; CI [0.26, 0.28]) when compared to the needs of individuals with psychiatric disorders, after controlling for year, age, gender, and race/ethnicity.

CONCLUSIONS

Additional research is needed to better understand the intersections of age, gender identity, race/ethnicity, the complexity of needs, and useful strengths. The involvement of practitioners, service organizations, researchers, and policymakers will be required to provide accessible, effective behavioral health services with cultural and developmental adaptations to support recovery.

Associations of Subjective Memory with Life Space and Neighborhood Built Environment in Older Adults in the ACTIVE Study

Objectives: To investigate the longitudinal association of life space and neighborhood and built environment (NBE) with subjective memory among individuals 65 and older, and the mediating role of depressive symptoms, a major correlate of life space mobility, NBE, and subjective memory. Methods: We examined community-dwelling participants in the Advanced Cognitive Training for Independent and Vital Elderly study (N = 2,622, Mean age = 73.7 years, 24.9% Black) across annual assessments of up to 3 years. Results: Baseline life space and NBE were positively associated with subjective memory, and these associations were partly mediated by depressive symptoms. Over time, higher baseline life space predicted a better subjective memory as one aged. Life space was concurrently associated with subjective memory across time, mediated by concurrent depressive symptoms. Discussion: Potentially modifiable environmental factors such as life space and NBE appear to influence level and change in subjective memory as we age. Interventions supporting movement in our environments may help offset subjective memory problems, a potential early sign of dementia.

The social determinants of mental health and disorder: evidence, prevention and recommendations

People exposed to more unfavourable social circumstances are more vulnerable to poor mental health over their life course, in ways that are often determined by structural factors which generate and perpetuate intergenerational cycles of disadvantage and poor health. Addressing these challenges is an imperative matter of social justice. In this paper we provide a roadmap to address the social determinants that cause mental ill health. Relying as far as possible on high-quality evidence, we first map out the literature that supports a causal link between social determinants and later mental health outcomes. Given the breadth of this topic, we focus on the most pervasive social determinants across the life course, and those that are common across major mental disorders. We draw primarily on the available evidence from the Global North, acknowledging that other global contexts will face both similar and unique sets of social determinants that will require equitable attention. Much of our evidence focuses on mental health in groups who are marginalized, and thus often exposed to a multitude of intersecting social risk factors. These groups include refugees, asylum seekers and displaced persons, as well as ethnoracial minoritized groups; lesbian, gay, bisexual, transgender and queer (LGBTQ+) groups; and those living in poverty. We then introduce a preventive framework for conceptualizing the link between social determinants and mental health and disorder, which can guide much needed primary prevention strategies capable of reducing inequalities and improving population mental health. Following this, we provide a review of the evidence concerning candidate preventive strategies to intervene on social determinants of mental health. These interventions fall broadly within the scope of universal, selected and indicated primary prevention strategies, but we also briefly review important secondary and tertiary strategies to promote recovery in those with existing mental disorders. Finally, we provide seven key recommendations, framed around social justice, which constitute a roadmap for action in research, policy and public health. Adoption of these recommendations would provide an opportunity to advance efforts to intervene on modifiable social determinants that affect population mental health.

Well-being Effects of a Subsidy Retention Fund for Renovation of Dwellings of Locked-in Owners in Ghent

With its subsidy retention fund, the city of Ghent targets homeowners, who live in a dwelling of bad quality and do not have the resources to renovate or move out. Being in this no-choice situation, they are locked-in homeowners. Through this innovative policy instrument, Ghent aims to improve the quality of its housing stock targeting households who may not take up other renovation-encouraging instruments. To reach the households who would otherwise not be able to renovate, important efforts in outreaching and offering technical and social guidance accompany the renovation subsidy. Guidance activities substantially increase the cost of the instrument, but in reaching the households living in bad-quality houses, it has the potential to create major benefits not only technically but also socially as housing quality is related to well-being. Generally, the identification of a causal relationship is difficult as well-being and its mediators are complex matters. This case offered a unique opportunity to collect information from the beneficiaries on a range of well-being domains both before the renovation of their dwelling and after the renovation. Even though the research was restricted to short-term effects, the results suggest that improvements in different domains of well-being can be linked to the improvement of housing quality. These improvements in well-being in Ghent show that (local) government spending in housing renovation of locked-in homeowners can be an instrument to achieve social progress.

The architecture of mental health: identifying the combination of apartment building design requirements for positive mental health outcomes

Background

Housing quality is a crucial determinant of mental health. While the construction of high-rise buildings is a popular policy strategy for accommodating population growth in cities, there is considerable debate about the health consequences of living in poorly designed apartments. Drawing on three Australian state government apartment design policies introduced to improve apartment design quality, this study aimed to identify the combination of design requirements that were optimally supportive of positive mental health.

Methods

K-means cluster analyses identified groups of buildings (n = 172) that were homogenous in their implementation of a mix of n = 80 measured design requirements. Positive mental health was measured using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Linear mixed-effects models controlling for demographic characteristics, self-selection factors and clustering of participants within buildings compared residents in the different clusters.

Findings

Residents in the "high policy performance buildings", characterised by having a greater implementation of n = 29 design requirements across nine design elements, had significantly higher (+1.96 points) WEMWBS scores compared with residents in the "low policy performance buildings".

Interpretation

This study is the first to empirically identify a mix of policy-specific architecture design requirements that are associated with positive mental health in apartment residents. These findings provide vital empirical evidence to inform national and international apartment and high-rise housing policies, and design instruments and practices to protect people's health in apartment dwellings.

Spatializing stigma-power: Mental health impacts of spatial stigma in a legally-excluded settlement in Mumbai, India

In disadvantaged neighborhoods such as informal settlements (or "slums" in the Indian context), infrastructural deficits and social conditions have been associated with residents' poor mental health. Within social determinants of health framework, spatial stigma, or negative portrayal and stereotyping of particular neighborhoods, has been identified as a contributor to health deficits, but remains under-examined in public health research and may adversely impact the mental health of slum residents through pathways including disinvestment in infrastructure, internalization, weakened community relations, and discrimination. Based on analyses of individual interviews (n = 40) and focus groups (n = 6) in Kaula Bandar (KB), an informal settlement in Mumbai with a previously described high rate of probable common mental disorders (CMD), this study investigates the association between spatial stigma and mental health. The findings suggest that KB's high rate of CMDs stems, in part, from residents' internalization of spatial stigma, which negatively impacts their self-perceptions and community relations. Employing the concept of stigma-power, this study also reveals that spatial stigma in KB is produced through willful government neglect and disinvestment, including the denial of basic services (e.g., water and sanitation infrastructure, solid waste removal). These findings expand the scope of stigma-power from an individual-level to a community-level process by revealing its enactment through the actions (and inactions) of bureaucratic agencies. This study provides empirical evidence for the mental health impacts of spatial stigma and contributes to understanding a key symbolic pathway by which living in a disadvantaged neighborhood may adversely affect health.

Social inequalities in self-perceived health in Chile, does the urban environment matter?: a cross-sectional study

BACKGROUND

The health of a population is determined by urban factors such as the physical, social and safety environment, which can be modified by urban regeneration policies. The aim of this study was to analyze the associations of elements of the social, physical and safety environment of the neighborhood in the urban context with self-perceived health (SPH), according to axes of inequality, such as gender and educational level in Chile in 2016.

METHODS

Cross-sectional study using a nationally representative population-based survey of Chile. We used data from the 2016 National Survey of Quality of Life and Health. Poor SPH in the urban population older than 25 years was analyzed in relation to social, physical and safety environment variables. Poisson multilevel regression models were estimated to obtain prevalence ratios (PR) and their respective 95% confidence intervals (95%CI). All analyses were stratified by sex and educational level.

RESULTS

SPH was worse in women than in men, especially in those with a lower education level. Poor SPH was associated with lack of support networks (PR = 1.4; 95%CI = 1.1-1.7), non-participation in social organizations (PR = 1.3; 95%CI = 1.1-1.6) and perceived problems with the quality of public space (PR = 1.3; 95%CI = 1.2-1.5) in women with a medium-high educational level and with a feeling of not belonging to the neighborhood (PR = 1.5; 95%CI = 1.2-1.8) and the perception of pollution problems (PR = 1.2; 95%CI = 1.0-1.4) in women with a low educational level. A feeling of unsafety was associated with both educational levels (PR = 1.3; 95%CI = 1.0-1.5). Poor SPH was associated with the feeling of not belonging (PR = 1.7; 95%CI = 1.2-2.5), and unsafety (PR = 2.1; 95%CI = 1.8-2.4) in men with a medium-high educational level, while there were fewer associations in men with a lower education level.

CONCLUSIONS

Urban interventions are recommended to improve the health of the resident population and should take into account axes of inequality.

The Association between Physical Environment and Externalising Problems in Typically Developing and Neurodiverse Children and Young People: A Narrative Review

The physical environment is of critical importance to child development. Understanding how exposure to physical environmental domains such as greenspace, urbanicity, air pollution or noise affects aggressive behaviours in typical and neurodiverse children is of particular importance given the significant long-term impact of those problems. In this narrative review, we investigated the evidence for domains of the physical environment that may ameliorate or contribute to the display of aggressive behaviours. We have considered a broad range of study designs that include typically developing and neurodiverse children and young people aged 0-18 years. We used the GRADE system to appraise the evidence. Searches were performed in eight databases in July 2020 and updated in June 2022. Additional articles were further identified by hand-searching reference lists of included papers. The protocol for the review was preregistered with PROSPERO. Results: We retrieved 7174 studies of which 67 are included in this review. The studies reported on green space, environmental noise and music, air pollution, meteorological effects, spatial density, urban or rural setting, and interior home elements (e.g., damp/sensory aspects/colour). They all used well validated parent and child reported measures of aggressive behaviour. Most of the studies were rated as having low or unclear risk of bias. As expected, noise, air pollution, urbanicity, spatial density, colour and humidity appeared to increase the display of aggressive behaviours. There was a dearth of studies on the role of the physical environment in neurodiverse children. The studies were heterogeneous and measured a range of aggressive behaviours from symptoms to full syndromes. Greenspace exposure was the most common domain studied but certainty of evidence for the association between environmental exposures and aggression problems in the child or young person was low across all domains. We found a large knowledge gap in the literature concerning neurodiverse children, which suggests that future studies should focus on these children, who are also more likely to experience adverse early life experiences including living in more deprived environments as well as being highly vulnerable to the onset of mental ill health. Such research should also aim to dis-aggregate the underlying aetiological mechanisms for environmental influences on aggression, the results of which may point to pathways for public health interventions and policy development to address inequities that can be relevant to ill health in neurodiverse young people.

Area-level deprivation, neighbourhood factors and associations with mental health

The COVID-19 pandemic saw residential neighbourhoods become more of a focal point in people's lives, where people were greater confined to living, working, and undertaking leisure in their locality. This study investigates whether area-level deprivation and neighbourhood conditions influence mental health, accounting for demographic, socio-economic and health circumstances of individuals. Using nationally representative data from Ireland, regression modelling revealed that area-level deprivation did not in itself have a discernible impact on mental health status (as measured using the Mental Health Inventory-5 instrument and the Energy and Vitality Index), or likelihood of having suffered depression in the previous 12 months. However, positive perceptions of area safety, service provision, and area cleanliness were associated with better mental health, as was involvement in social groups. Broad ranging policies investing in neighbourhoods, could have benefits for mental health, which may be especially important for deprived communities.

Trauma-Informed Design of Supported Housing: A Scoping Review through the Lens of Neuroscience

There is growing recognition of the importance of the design of the built environment in supporting mental health. In this context, trauma-informed design has emerged as a new field of practice targeting the design of the built environment to support wellbeing and ameliorate the physical, psychological and emotional impacts of trauma and related pathologies such as Post Traumatic Stress Disorder (PTSD). With high levels of prevalence of PTSD among people escaping homelessness and domestic violence, a priority area is the identification and application of evidence-based design solutions for trauma-informed supported housing. This study sought to examine the scope of existing evidence on the relationship between trauma, housing and design and the correlation of this evidence with trauma-informed design principles, and to identify gaps and opportunities for future research. In response to the commonly articulated limitations of the evidence-base in built environment design research, we combined a scoping review of literature on trauma, housing and design with insights from neuroscience to focus and extend understanding of the opportunities of trauma-informed design. We found that while limited in scope, there is strong alignment between existing evidence and the principles of trauma-informed design. We also identify three areas of future research related to the key domains of safety and security; control; and enriched environments.

A Meta-Analysis on the Influence of Age-Friendly Environments on Older Adults' Physical and Mental Well-Being

The importance of age-friendly environments (AFEs) for older adults has been empirically and theoretically highlighted by the extant literature. However, the strength of the association between environments and older adults’ well-being has not been comprehensively quantified. Given the different attributes of the physical and mental dimensions, this meta-analysis aims to synthesise and quantify the association between AFEs and the physical and mental well-being of older adults. Fourteen eligible studies were included in this analysis: among which eight explored the link between AFEs and physical well-being, and eleven investigated AFEs in association with mental well-being. A random-effects model showed a small but significant correlation between AFEs and the mental well-being of older adults (r = 0.160, 95% CI [0.084, 0.224], p < 0.001), and the correlation between AFEs and physical well-being was also significant (r = 0.072, 95% CI [0.026, 0.118], p < 0.01). The number of environmental factors involved in AFEs moderated the association with physical well-being, from which the association was only significant among studies focusing on fewer environmental factors (n < 6). Results of this meta-analysis indicated that AFEs may be more effective in promoting the emotions of older adults, compared to ameliorating their physical functioning. The limitations of current empirical studies and directions for future research in the field of environmental gerontology were also discussed.

The role of physical environmental characteristics and intellectual disability in conduct problem trajectories across childhood: A population-based Cohort study

BACKGROUND

The paucity of research investigating the role of the physical environment in the developmental progression of conduct problems and the potential moderating effects of intellectual disability (ID) is surprising, given the clinical relevance of elucidating environmental determinants of disruptive behaviours.

AIMS

To use data from a large UK cohort study to assess associations between physical environmental exposures, ID, and conduct problem trajectories.

METHOD

The sample included 8168 Millennium Cohort Study children (1.9% with ID). Multilevel growth curve modelling was used to examine the role of physical environment characteristics in the developmental trajectories of conduct problems after adjustments for ID status.

RESULTS

Exposure to external environmental domains was not associated with differences in children's conduct problems across development. Alternatively, internal aspects of the household environment: spatial density (b = 0.40, p < .001) and damp problems (b = 0.14, p < .001) were both significantly associated with increased trajectories. Various individual and familial covariates were positively associated with conduct problems over time, including: presence of ID (b = 0.96, p < .001), autism spectrum disorder (b = 1.18, p < .001), male sex (b = 0.26, p < .001), poverty (b = 0.19, p < .001), maternal depression (b = 0.65, p < .001), and non-nuclear family structure (b = 0.35, p < .001). Positive ID status appeared to moderate the effects of internal household spatial density, reporting a non-linear negative association with spatial density and conduct problems across development (b = -1.08, p < .01).

CONCLUSIONS

Our findings highlight the potential harmful consequences of poor internal residential conditions on children's development of disruptive behaviours.

A Systematic Review of the Effects of Urban Living on Suicidality and Self-Harm in the UK and Ireland

We conducted a systematic review to answer the following: (a) Is there any evidence to support increased prevalence of suicidality and self-harm (i.e. self-harm or suicidality) in urban versus rural environments? (b) What aspects of the urban environment pose risk for suicidality and self-harm? Thirty-five studies met our criteria. Our findings reflect a mixed picture, but with a tendency for urban living to be associated with an increased risk of suicidality and self-harm over rural living, particularly for those living in deprived areas. Further research should focus on the clustering and additive effects of risk and protective factors for suicidality and self-harm in urban environments.

Effect of Housing Quality on the Mental Health of University Students during the COVID-19 Lockdown

COVID-19 outbreak imposed rapid and severe public policies that consistently impacted the lifestyle habits and mental health of the general population. Despite vaccination, lockdown restrictions are still considered as potential measures to contrast COVID-19 variants spread in several countries. Recent studies have highlighted the impacts of lockdowns on the population's mental health; however, the role of the indoor housing environment where people spent most of their time has rarely been considered. Data from 8177 undergraduate and graduate students were collected in a large, cross-sectional, web-based survey, submitted to a university in Northern Italy during the first lockdown period from 1 April to 1 May 2020. Logistic regression analysis showed significant associations between moderate and severe depression symptomatology (PHQ-9 scores ≥ 15), and houses with both poor indoor quality and small dimensions (OR = 4.132), either medium dimensions (OR = 3.249) or big dimensions (OR = 3.522). It was also found that, regardless of housing size, poor indoor quality is significantly associated with moderate-severe depressive symptomatology. Further studies are encouraged to explore the long-term impact of built environment parameter modifications on mental health, and therefore support housing and public health policies.

Physical home learning environments for digitally-supported learning in academic continuing education during COVID-19 pandemic

Since the outbreak of the COVID-19 pandemic in 2020, digital technologies for distance learning have been used in educational institutions worldwide, raising issues about social implications, technological development, and teaching and learning strategies. While disparities regarding access to technical equipment and the internet ('the digital divide') have been the subject of previous research, the physical learning environment of learners participating in online learning activities has hardly been investigated. In this study, the physical-spatial conditions of learning environments, including technical equipment for distance learning activities and their influence on adult learners in academic continuing education during initial COVID-19 restrictions, were examined. Data were collected with an online survey sent to all students enrolled in an Austrian continuing education university, together with a small number of semi-structured interviews. A total of 257 students participated in the survey during the 2020 summer semester. Our findings provide insights in two infrequently-studied areas in learning environment research: the physical learning environment for online learning and the learning environment in academic continuing education. The study illustrates that students in academic continuing education have spacious living conditions and almost all the equipment necessary for digitally-supported learning. According to gender and household structure, significant differences were found regarding technical equipment, ergonomic furniture and availability of a dedicated learning place. In their learning sessions during the restrictions, students reported low stress levels and positive well-being. The more that they perceived that their physical learning environment was meeting their needs, the higher were their motivation and well-being and the lower was their stress. Their learning experience was further improved by the extent to which they had a separate and fixed learning place that did not need to be coordinated or shared with others. The study contributes to the literature on creating conducive learning environments for digitally-supported online learning for adult learners.

Systematic review of quantitative studies assessing the relationship between environment and mental health in rural areas

OBJECTIVE

Physical and natural environments might strongly influence mental health and well-being. Many studies have examined this relationship in urban environments, with fewer focused on rural settings. The aim of this systematic review was to synthesise quantitative evidence for the relationship between environmental factors (drought, climate and extreme weather events, land use/environmental degradation, green space/vegetation, engagement in natural resource management activities) and mental health or well-being in rural areas.

DESIGN

Following a systematic search of three databases (PsycINFO, MEDLINE and Web of Science), 4368 articles were identified, of which 28 met eligibility criteria for inclusion in the review.

RESULTS

Poorer mental health and well-being was typically found to have an association with extreme climate or weather events and environmental degradation. The observed relationships were largely assessed at area-wide or community levels.

CONCLUSIONS

Studies examining the relationship between the environmental condition of land and mental health at an individual level, particularly within farms, are lacking. Addressing this gap in research requires interdisciplinary expertise and diverse methodology. Few studies examined the effects of natural resource management practices/principles or biodiversity on mental health. While there is evidence that extreme climate or weather events have a negative impact on mental health in rural areas, there remain considerable gaps in our knowledge of how rural environments influence mental health and well-being.

Urban Parks as Perceived by City Residents with Mobility Difficulties: A Qualitative Study with In-Depth Interviews

Urban green spaces make an invaluable contribution to the health and well-being of all city residents. Therefore, urban park quality and accessibility are crucial factors in stimulating physical and mental health benefits. This study aimed to assess the quality of urban parks and their accessibility as reported by people with mobility difficulties (seniors, blind and partially sighted people). Four key features of a place (accessibility and linkages, comfort and image, uses and activities and sociability) were considered in an in-depth-interviews (IDI) and "walk-and-talk" interviews. Study results indicate a problem of accessibility of urban parks for people with mobility difficulties (uneven gravel surfaces). However, non-physical aspects of park visits (social activities, cultural events, place branding) were reported as essential factors in explaining the motivation for park visits. Despite individual preferences, experience or reported difficulties, all respondents' attitudes towards park trips were positive. Therefore, we assume that accessibility is more than just physical comfort. Cultural and social activities play an important role in motivating people with a disability to visit a park.

Strategic Assessment of Neighbourhood Environmental Impacts on Mental Health in the Lisbon Region (Portugal): A Strategic Focus and Assessment Framework at the Local Level

Scientific evidence shows that each place/environment generates specific conditions with associated impacts on the mental health and well-being of the population. A holistic, multilevel and integrated environmental approach to mental health enhances the understanding of this phenomena, supporting the local decision-making processes to improve spatial planning of neighbourhood environments. The aim of this study is to develop a strategic assessment framework, based on four municipalities in the Lisbon Region (Portugal), that explores policy and planning initiatives capable of generating favourable neighbourhood environmental conditions for mental health while also detecting risks. Using baseline results of significant statistical associations between individuals’ perceptions of their neighbourhood environment and their mental health in the Lisbon Region, a Strategic Focus on Environmental and Mental Health Assessment framework (SEmHA) was built, by applying the methodology “Strategic Thinking for Sustainability” in Strategic Environmental Assessment, developed by Partidário in 2012. Taking into account the promotion of the population’s mental health, four critical decision factors of neighbourhood environments were identified: (1) public space quality (e.g., improving sense of place), (2) physical environment quality (e.g., low levels of noise exposure), (3) professional qualification and creation of economic activities (e.g., attracting new economic activities), and (4) services and facilities (e.g., improving access to health and education services). The proposed strategic focus and assessment framework contributes to ensuring that interventions in neighbourhood environments truly achieve community mental health benefits and reduce inequalities, thus helping policy makers to assess impacts at the local level.

Space and Well-Being in High Security Environments

Research into the spatial dimensions of deprivation of liberty and psychiatric hospitalization has a long and complex tradition. In this context, the increasing numbers of prisoners and patients in forensic hospitals have impressively shown how difficult it is to ensure security, therapy and rehabilitation when space is scarce or not well-suited. In this narrative review, we present the main findings of recent lines of research on spaces in prisons and forensic psychiatric wards, with particular attention to the links between overcrowding in prisons and secure forensic psychiatric hospitals and violence, the foundations of prison and hospital architecture, and on how the design of spaces in prisons and hospitals can influence well-being. We assess and discuss these findings in the context of the current debate on how well-being in secure spaces can support the achievement of rehabilitation goals even in overcrowded institutions.

Permanent Supportive Housing Design Characteristics Associated with the Mental Health of Formerly Homeless Adults in the U.S. and Canada: An Integrative Review

The built environment directly and indirectly affects mental health, especially for people transitioning from long-term homelessness to permanent supportive housing (PSH) who often experience co-occurring behavioral health challenges. Despite a rapid increase in PSH availability, little research examines influences of architecture and design within this context. This integrative review synthesized limited research on PSH design in the U.S. and Canada to identify built environment characteristics associated with PSH residents’ mental health, highlight gaps in the literature, and prioritize future research directions. A systematic search for peer-reviewed articles was conducted using nine databases drawing from multiple disciplines including architecture, environmental psychology, interior design, psychology, psychiatry, medicine, and nursing. Seventeen articles met inclusion criteria. Study design, methodology, built environment properties, place attributes, and relevant findings were extracted and iteratively analyzed. Three domains relevant to architecture and design were identified related to home, ontological security, and trauma sensitivity; dwelling unit type, privacy, control, safety, housing quality and location, and access to amenities; and shared common space. Integrative review results emphasize the potential of architecture and design to contribute to improved built environment quality and mental health outcomes among PSH residents. Methodological limitations and directions for future research are also discussed.

The urban public realm and adolescent mental health and wellbeing: A systematic review

Adolescent mental health is becoming a critical concern. Mental illness rates are rising and many psychological disorders first present symptoms during teenage years. Studies consistently show associations between the built environment and mental health, including internalising mental health disorders in adults, but the evidence for adolescents is less robust and few studies attempt to isolate causality. This review examines the relationship between the urban public realm and adolescent mental health and wellbeing. Our search yielded 24 studies for inclusion. We undertook qualitative synthesis of 20 cross-sectional studies and conducted a separate quality analysis of four longitudinal studies. Greenspace and neighbourhood quality are associated with adolescent mental health and wellbeing although this may be due more to residual confounding, selection effects and same-source bias than evidence for a causal effect. Furthermore, the few longitudinal studies that seek to test causality remain prone to these biases. Overall, we find little evidence of an effect of the urban public realm on adolescent mental health and wellbeing, which, we argue, reflects the difficulty of researching complex pathways between environments and health and highlights a challenge to the field. To address this challenge, we propose a research agenda that prioritises more and better data drawn from diverse study designs, and more and better theories developed from diverse epistemologies.

Mental Well-Being and the Influence of Place: Conceptual Approaches for the Built Environment for Planning Healthy and Walkable Cities

Promotion of healthy cities has prompted urban planners and designers to build new conceptual frameworks to improve the design of public spaces, in which mental well-being emerges as a fundamental concept. Mental well-being is related to spatial design, with increasing attention being paid to the built environment as an important predictor of mental well-being. The objective of this article is to advance and contribute new knowledge about the characteristics of the built environment and its potential benefits for mental well-being. A meta-analysis is carried out on various empirical and theoretical approaches from the literature. Using a WOS database as a case study, a methodology based on a bibliometric analysis is proposed to examine which elements of the built environment impact mental well-being in research between 1975 and 2020, using the HistCites and VOSviewer tools. The results show that there are six thematic axes related to the built environment that would favor greater mental well-being in public spaces: walkability, density, spatial design, environmental noise, green areas and social interaction. The six thematic axes are critically analyzed and integrated into a conceptual framework to address the impacts of the built environment on mental well-being in the planning of cities. It concludes with a discussion on the implications of these concepts for urban public policy and the promotion of healthier and more sustainable and walkable environments in Latin American cities.

How Do Urban Environments Affect Young People's Mental Health? A Novel Conceptual Framework to Bridge Public Health, Planning, and Neurourbanism

Childhood and adolescence are crucial periods for mental and social development. Currently, mental illness among young people is a global epidemic, and rates of disorders such as depression and anxiety are rising. Urban living, compared with rural living, is linked with a higher risk of serious mental illness, which is important because the world is urbanizing faster than ever before. Urban environments and their landscapes, designs, and features influence mental health and well-being. However, no conceptual frameworks to date have detailed the effect of urban environments on young people's mental health, and few studies have considered the growing role of digital and social media in this relationship, leading to calls for the development of holistic approaches to describe this relationship. This article synthesizes existing knowledge on urban places (both built and natural environments) and mental health in the public health and urban planning literature and examines the emerging field of neurourbanism (a multidisciplinary study of the effect of urban environments on mental health and brain activity) to enhance current practice and research. We developed 2 novel conceptual frameworks (1 research-oriented, 1 practice-oriented), adapted from Bronfenbrenner's socioecological model, that focus on the relationship between urban environments and young people's mental health. We added a digital and social media contextual level to the socioecological model, and we applied a multilayer concept to highlight potential cross-field interactions and collaborations. The proposed frameworks can help to guide future practice and research in this area.

Effects of an urban regeneration program on related social determinants of health in Chile: A pre-post intervention study

Urban regeneration programs, such as "Programa Quiero mi Barrio" (PQMB) that is carried out in neighborhoods with greater deprivation across Chile, can improve health and quality of life in socio-economically deprived neighborhoods. The aim of this study was to analyze the effects of this program on the physical, social, and safety environments of neighborhoods intervened between 2011 and 2018, according to gender and socioeconomic position. Four indices and six sub-indices were constructed to measure physical, social, and safety environments of the neighborhoods. We conducted a pre- and post-intervention analysis with 2095 people using linear models adjusted for repeated measurements. After the intervention, participants had an improved perception of physical, social, and safety environments, as well as the use of spaces, particularly among women and people with higher levels of education. Therefore, the PQMB program is a form of public policy that can improve the quality of life and health of people living in underprivileged areas.

Exploring how the urban neighborhood environment influences mental well-being using walking interviews

Mental well-being in cities is being challenged worldwide and a more detailed understanding of how urban environments influence mental well-being is needed. This qualitative study explores neighborhood factors and their interactions in relation to mental well-being. Individual semi-structured walking interviews were conducted with 28 adults living in the Brussels-Capital Region. This paper provides a detailed description of physical neighborhood factors (green-blue spaces, services, design and maintenance, traffic, cellphone towers) and social neighborhood factors (neighbor ties, neighbor diversity, social security) that link to mental well-being. A socio-ecological framework is presented to explain interactions among those neighborhood factors, and personal and institutional factors, in relation to mental well-being. The findings are linked to existing concepts and theories to better understand the mechanisms underlying the associations between the urban neighborhood environment and mental well-being. Finally, implications of the walking interview method are discussed.

Transportation noise exposure and anxiety: A systematic review and meta-analysis

BACKGROUND

Exposure to transportation noise is hypothesized to contribute to anxiety, but consistent associations have not been established.

OBJECTIVE

To provide a comprehensive synthesis of the literature by examining associations between traffic-related noise (i.e., road traffic noise, railway noise, aircraft noise and mixed traffic noise) and anxiety.

METHODS

We systematically searched Web of Science, Scopus, Embase, PubMed, and PsycINFO for English-language observational studies published up to February 2020 reporting on the traffic noise-anxiety association. We appraised the risk of bias using an assessment tool and the quality of evidence following established guidelines. A random-effects meta-analysis was performed for pooled and separated traffic-related noise sources.

RESULTS

Of the 3575 studies identified, 11 fulfilled the inclusion criteria and 9 studies were appropriate for meta-analysis. For the pooled overall effect size between transport noise and anxiety, we found 9% higher odds of anxiety associated with a 10 dB(A) increase in day-evening-night noise level (L_den), with moderate heterogeneity (OR = 1.09, 95% CI: [0.97; 1.23], I² = 70%). The association was more likely to be significant with more severe anxiety (OR = 1.08, 95% CI: [1.01; 1.15], I² = 48%). Sub-group analysis revealed that the effects of different noise sources on anxiety were inconsistent and insignificant. The quality of evidence was rated as very low to low.

CONCLUSIONS

Our findings support the hypothesis of an association between traffic noise and more severe anxiety. More high-quality studies are needed to confirm associations between different noise types and anxiety, as well as to better understand underlying mechanisms.

The Effect of Discrimination on Stress among Public Housing Residents: A Comparative Study between Social-Mix and Independent Public Housing Complexes

This study aims to examine the differential effect of discrimination on stress between social-mix and independent public housing complexes. We analyzed the 2017 Seoul Public Housing Residents Panel Study data that were collected from public housing residents living in Seoul, Korea by running ordinal logit analyses. The empirical analysis shows that discrimination has a lower effect on stress in social-mix housing complexes than in independent public housing complexes. In addition, the moderating effect of community-based activities on the relationship between discrimination and stress was found in the independent public housing complex model.

The Association between Green Space and Adolescents' Mental Well-Being: A Systematic Review

This systematic review summarised and evaluated the evidence for associations between green space and adolescents’ mental well-being. The PRISMA statement guidelines were followed for reporting systematic reviews. Fourteen articles met the inclusion criteria for this review. Synthesis suggests beneficial associations between green space exposure and reduced stress, positive mood, less depressive symptoms, better emotional well-being, improved mental health and behaviour, and decreased psychological distress in adolescents. Several studies found the relationship varied by demographic and socio-economic factors. The limited number of studies and the risk of bias were the main limitations, together with heterogeneity regarding green space and mental well-being assessments. Overall, this review highlights the potential contribution of green space in schoolyards. Improving the availability, accessibility and quality of green space is likely to generate positive impacts on adolescents’ mental well-being. More consistent evidence on the use of different types of green space and perceptions of features are needed in the future.

Disentangling how the built environment relates to children's well-being: Participation in leisure activities as a mediating pathway among 8-year-olds based on the Norwegian Mother and Child Cohort Study

There is scarce insight into the role of the built environment for children's subjective well-being. In an attempt to increase our knowledge on this matter, we conducted a cross-sectional study comprising 23,043 children from the Norwegian Mother and Child Cohort Study. Information about children's leisure activities and their moods and feelings were linked to geospatial data on green space, facilities and population density to assess whether these built characteristics are related to subjective well-being and if participating in leisure activities is a mediator in such relations. We found that children having a park and more playgrounds/sports fields in the neighborhood, as well as those living in more densely populated areas, had more depressive moods and negative feelings. However, participating in leisure-time physical activity, organized activities and social activity with friends mediated these relations and contributed to counterbalancing some of the negative associations observed. The findings suggest that planners and policy makers should focus on ensuring children have neighborhood resources and venues that could support engagement in leisure activities that add positive experiences for their subjective well-being.

Urban regeneration policies and mental health in a context of economic crisis in Andalusia (Spain)

Literature suggests that urban regeneration policies might contribute towards improving mental health of residents, but to date there is a lack of empirical research on how these policies and downward social mobility can interact and influence health outcomes. The current study aims to explicitly test whether regeneration policies implemented in deprived Andalusian urban places (southern Spain) moderate the use of anxiolytics and/or antidepressants, taking into consideration families' downward social mobility during the recent period of economic crisis in Spain. We designed a post intervention survey to retrospectively compare the evolution of psychotropic drug consumption in target and comparison areas. We observe a general increase in the use of anxiolytics and/or antidepressants from 2008 to 2015, specifically for people in whose families the economic crisis had the greatest impact (odds ratio = 2.18; p value < 0.001). However, better evolution is observed among residents of the target areas compared with residents of similar urban areas where this kind of polices have been not in force (odds ratio = 0.50; p value < 0.05). Therefore, urban regeneration policies might act as moderators of the risk of mental health, particularly when people are subject to the loss of individual/family resources in urban vulnerable contexts.

Living liveable? RESIDE's evaluation of the "Liveable Neighborhoods" planning policy on the health supportive behaviors and wellbeing of residents in Perth, Western Australia

BACKGROUND

The RESIDential Environments (RESIDE) project is a unique longitudinal natural experiment designed to evaluate the health impacts of the "Liveable Neighbourhoods" planning policy, which was introduced by the Western Australian government to create more walkable suburbs.

OBJECTIVES

To summarize the RESIDE evidence of the impact of the planning policy on a range of health-supportive behaviours and wellbeing outcomes and to assess the consistency and direction of the estimates of associations.

METHODS

An audit of 26 RESIDE research papers (from 2003 to 2012) identified the number of positive associations (statistically significant and consistent with policy expectations), negative associations (statistically significant and inconsistent with policy expectations), and null findings from multiple-exposure models between objective and perceived measures of 20 policy design requirements and 13 health-supportive behaviors and wellbeing outcomes.

RESULTS

In total 332 eligible estimates of associations (n = 257 objective measures and n = 75 perceived measures) were identified. Positively significant findings were detected for: 57% of walking estimates with objectively measured policy design features (negative = 3%; null = 40%) (n = 115) and 54% perceived measures (negative = 0%; null = 33%) (n = 27); 42% of sense of community estimates with objectively measured of policy design features (negative = 8%; null = 50%) (n = 12) and 61% perceived measures (negative = 8%; null = 31%) (n = 13); 39% of safety or crime-related estimates with objectively measured of policy design features (negative = 22%; null = 39%) (n = 28) and 100% perceived measures (n = 7). All (n = 4) estimates for mental health outcomes with objectively measured policy-related design features were positively significant.

CONCLUSIONS

The synthesis of findings suggests that new suburban communities built in accordance with the "Liveable Neighbourhoods" policy have the potential to encourage health supportive behaviors and wellbeing outcomes including transport and recreation walking, and to create neighborhoods with a stronger sense of community where residents may feel safer.

Overview of "Systematic Reviews" of the Built Environment's Effects on Mental Health

Good mental health is related to mental and psychological well-being, and there is growing interest in the potential role of the built environment on mental health, yet the evidence base underpinning the direct or indirect effects of the built environment is not fully clear. The aim of this overview is to assess the effect of the built environment on mental health-related outcomes. Methods. This study provides an overview of published systematic reviews (SRs) that assess the effect of the built environment on mental health. We reported the overview according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases searched until November 2019 included the Cochrane Database of Systematic Reviews, EMBASE, MEDLINE (OVID 1946 to present), LILACS, and PsycINFO. Two authors independently selected reviews, extracted data, and assessed the methodological quality of included reviews using the Assessing Methodological Quality of Systematic Reviews-2 (AMSTAR-2). Results. In total, 357 records were identified from a structured search of five databases combined with the references of the included studies, and eleven SRs were included in the narrative synthesis. Outcomes included mental health and well-being, depression and stress, and psychological distress. According to AMSTAR-2 scores, the quality assessment of the included SRs was categorized as "high" in two SRs and as "critically low" in nine SRs. According to the conclusions of the SRs reported by the authors, only one SR reported a "beneficial" effect on mental health and well-being outcomes. Conclusion. There was insufficient evidence to make firm conclusions on the effects of built environment interventions on mental health outcomes (well-being, depression and stress, and psychological distress). The evidence collected reported high heterogeneity (outcomes and measures) and a moderate- to low-quality assessment among the included SRs.

Health Impact Assessment (HIA) of a fluvial environment recovery project in a medium-sized Spanish town

INTRODUCTION

The Interdepartamental Public Health Plan of Catalonia (2014) seeks to enforce Health in All Policies (HiAP) at the regional and local levels. Within this context, the City Council of Sant Andreu de la Barca (SAB), the Metropolitan Area of Barcelona (MAB), and the Public Health Agency of Catalonia started a Health Impact Assessment (HIA) of an urbanistic redesign of the Llobregat fluvial area in SAB, the results of which are presented in this paper.

METHODOLOGY

In 2018, after a HIA screening, a prospective nonquantitative HIA was conducted. Politicians, professionals, and citizens participated in identifying potential impacts. Impacts were prioritized and linked to health determinants, scientific evidence, and potentially affected social groups. Afterwards, recommendations were formulated in order to improve the health impacts of the project. Finally, indicators were selected to evaluate HIA implementation.

RESULTS

The HIA was successfully implemented with the participation of technicians and citizens of SAB. The health impacts identified were mainly related to environmental, public safety, lifestyle, socioeconomic, and political contexts. Ten recommendations were defined to minimize the potential negative health impacts of the project, with six of them directly included and only one dismissed due to incompatibility.

CONCLUSION

A HIA was successfully carried out in the medium-sized town of Catalonia, promoting Health in all Policies at a local level and improving health impacts of an urbanistic project.

Urban environment and mental health: the NAMED project, protocol for a mixed-method study

INTRODUCTION

Mental health issues appear as a growing problem in modern societies and tend to be more frequent in big cities. Where increased evidence exists for positive links between nature and mental health, associations between urban environment characteristics and mental health are still not well understood. These associations are highly complex and require an interdisciplinary and integrated research approach to cover the broad range of mitigating factors. This article presents the study protocol of a project called Nature Impact on Mental Health Distribution that aims to generate a comprehensive understanding of associations between mental health and the urban residential environment.

METHODS AND ANALYSIS

Following a mixed-method approach, this project combines quantitative and qualitative research. In the quantitative part, we analyse among the Brussels urban population associations between the urban residential environment and mental health, taking respondents' socioeconomic status and physical health into account. Mental health is determined by the mental health indicators in the national Health Interview Survey (HIS). The urban residential environment is described by subjective indicators for the participant's dwelling and neighbourhood present in the HIS and objective indicators for buildings, network infrastructure and green environment developed for the purpose of this project. We assess the mediating role of physical activity, social life, noise and air pollution. In the qualitative part, we conduct walking interviews with Brussels residents to record their subjective well-being in association with their neighbourhood. In the validation part, results from these two approaches are triangulated and evaluated through interviews and focus groups with stakeholders of healthcare and urban planning sectors.

ETHICS AND DISSEMINATION

The Privacy Commission of Belgium and ethical committee from University Hospital of Antwerp respectively approved quantitative database merging and qualitative interviewing. We will share project results with a wide audience including the scientific community, policy authorities and civil society through scientific and non-expert communication.

Evidence for Environmental Noise Effects on Health for the United Kingdom Policy Context: A Systematic Review of the Effects of Environmental Noise on Mental Health, Wellbeing, Quality of Life, Cancer, Dementia, Birth, Reproductive Outcomes, and Cognition

This systematic review commissioned by the UK Department for the Environment, Food and Rural Affairs (Defra), considers how the evidence base for noise effects on health has changed following the recent reviews undertaken for the WHO Environmental Noise Guidelines. This systematic review assesses the quality of the evidence for environmental noise effects on mental health, wellbeing, and quality of life; birth and reproductive outcomes; and cognition for papers published since the WHO reviews (mid-2015 to March 2019), as well as for cancer and dementia (January 2014 to March 2019). Using the GRADE methodology (Grading of Recommendations Assessment, Development and Evaluation) most evidence was rated as low quality as opposed to very low quality in the previous reviews. There is now low-quality evidence for a harmful effect of road traffic noise on medication use and interview measures of depression and anxiety and low quality evidence for a harmful effect of road traffic noise, aircraft noise, and railway noise on some cancer outcomes. Many other conclusions from the WHO evidence reviews remain unchanged. The conclusions remain limited by the low number of studies for many outcomes. The quantification of health effects for other noise sources including wind turbine, neighbour, industrial, and combined noise remains a research priority.

Exploring the contingent associations between functional limitations and depressive symptoms across residential context: a multilevel panel data analysis

Objectives: This study examines the multilevel relationship between functional limitations and depressive symptoms among community-dwelling US older adults, and how it is moderated by community environmental characteristics (neighborhood fear, social cohesion, structural disadvantage and residential stability).Method: Data come from two waves of National Social Life, Health and Aging Project (NSHAP) collected in 2005/2006 and 2010/2011, consisting of 2,261 individuals aged 57-85 (mean = 68.5; SD = 7.5) nested in 100 regional areas. Two-level hierarchical linear models are fitted to test if and to what extent limited physical capacity and neighborhood measures are interactively related to depressive symptoms.Results: Adjusting for confounders (e.g. age, gender, education, employment status, social support), we find a significant positive relationship between functional limitations and depressive symptoms. At the aggregate level, socially cohesive neighborhoods are negatively related to depression. Several cross-level interactions are also observed. First, the association between poor functional health and depression is greater in neighborhoods perceived to be less safe. It is also stronger in places with more structural disadvantages. Lastly, the physical impairment-depression link is more pronounced where there is higher residential stability, i.e., greater proportion of long-term residents.Conclusion: Our study bridges an important empirical gap in the literature. Prior studies have rarely investigated how the connection between functional limitations and depressive symptoms among older adults is conditioned by neighborhood characteristics. By using multilevel analysis of population-based longitudinal data, we show that physical space (neighborhood community) plays a critical role in understanding this important, yet understudied, relationship.

Predicting high and low levels of positive mental health among people living alone in the Lapland region of Finland

Purpose

The purpose of this paper is to investigate positive mental health (PMH) and factors related to it among those living alone in the sparsely populated area of the Lapland region.

Design/methodology/approach

The study utilises data from the Mental Health Survey of the Lapland region in Finland, covering 12 municipalities. The scores of short Warwick–Edinburgh Mental Well-Being Scale (sWEMWBS) were categorised into three levels of PMH. Logistic regression models were used to separately estimate the odds ratios for the high level of PMH compared with the moderate level of PMH and the low level of PMH compared with the moderate level.

Findings

Social support seemed to be very strongly associated with both low and high levels of PMH among people living alone. Participating in activities provided by organisations or societies decreased the odds of having low PMH. Among men, young age predicted low PMH.

Originality/value

The number of people living alone in Finland and other parts of Europe is increasing, yet there are few studies focusing on their positive mental health (PMH). Using scales such as sWEMWBS adds to the authors’ knowledge about the positive mental well-being of those living alone, especially in rural areas, thus making it possible to utilise mental health promotion interventions effectively and accordingly.

Close proximity to roadway and urbanicity associated with mental ill-health in older adults

Evidence for the association between built environment and mental ill health, especially in older population where mental ill health is common, remains inconclusive. We examined the association of roadway distance and urbanicity, measured as percentage of urban land use within 1 km from participants' residence, with mental ill-health in a longitudinal study of community-dwelling older adults in the United States between 2005 and 2006 and 2011-2012. We evaluated perceived stress, depression and anxiety symptoms using the Cohen's Perceived Stress Scale, the Center for Epidemiological Studies - Depression, and the Hospital Anxiety and Depression Scale - anxiety subscale, respectively. Increment in roadway distance was significantly associated with -0.03 point (95% CI: -0.05, -0.01) change in depressive score, with loneliness and PM_2.5 partially mediating the observed associations. Age, gender, race/ethnicity, and physical activity significantly modified the distance-depression association. Anxiety was inversely associated with roadway distance (-0.02; 95% CI: -0.03, 0.00), though the associations became insignificant upon adjusting for road traffic or noise. Urbanicity was significantly associated with 0.29 (95% CI: 0.10, 0.57) point increase in depressive symptoms in multivariable model; the association was partly mediated by loneliness, physical activity, social support and air pollution. No association was found between roadway distance and perceived stress, and between urbanicity, and anxiety and perceived stress. Built environment was associated with mental ill health, partially through pathways related to air pollution and certain individual characteristics (e.g. loneliness). Our study warrants further examination of the mediation and interaction of the built environment-mental health association.

Is the built environment associated with morbidity and mortality? A systematic review of evidence from Germany

The empirical evidence on this relationship mainly comes from Anglo-American countries whereas evidence from Germany is only emerging. Our objective is to provide a narrative overview and critical appraisal of the existing empirical evidence on the relationship between the built environment and morbidity/mortality in Germany. We conducted a systematic literature search where we included all empirical studies that linked the built environment aspects with morbidity or mortality outcomes. Findings were summarized and critically evaluated according to the Newcastle Ottawa Scale. Eighteen studies met the inclusion criteria and underwent in-depth analysis. Findings indicate that traffic exposure and green space tend to be associated with acute respiratory symptoms but not with chronic respiratory conditions. Evidence was inconsistent for the role of infrastructural aspects and urbanicity. Our review confirms the well-established association between traffic and respiratory health. Yet, the consistency between self-reported and objective measures of respiratory health should be investigated in more detail.

The effects of the London 2012 Olympics and related urban regeneration on physical and mental health: the ORiEL mixed-methods evaluation of a natural experiment

Background

There is limited evidence for public health policy-makers on the health impacts of urban regeneration programmes.

Objectives

To assess whether or not the London 2012 Olympic and Paralympic Games, and related urban regeneration, were associated with an increase in physical activity and mental health and well-being; to assess whether or not any benefits were sustained over time; and to capture the experiences of residents of the Olympic host boroughs.

Design

Quasi-experimental prospective cohort study of adolescents and their parents/carers, with a nested qualitative longitudinal study of families.

Setting

London boroughs of Newham, Barking and Dagenham, Tower Hamlets and Hackney.

Participants

A cohort of 2254 adolescents in 25 schools; a repeat cross-sectional study of parents/carers and a sample of 20 families for the qualitative study.

Intervention

The London 2012 Olympic and Paralympic Games, and urban regeneration primarily associated with the redevelopment of the Olympic Park for legacy use.

Primary outcome measures

Change in the proportion of respondents meeting physical activity recommendations (using self-reported physical activity); change in the proportion of respondents reporting depression and anxiety and change in well-being score.

Main results

At 6 months, adolescents who became inactive were less likely to come from the intervention borough (Newham) than from comparison boroughs [risk ratio (RR) = 0.69, 95% confidence interval (CI) 0.51 to 0.93]. At 18 months, there were no statistically significant differences between intervention and comparison boroughs for all adolescent physical activity and screen-time transitions. Those who visited the Olympic Park more than once a month were the least likely to remain inactive (RR 0.11, 95% CI 0.02 to 0.48) and the least likely to become inactive (RR 0.38, 95% CI 0.24 to 0.60) compared with those who were active at baseline and at the 18-month follow-up. No impacts on parental/carer physical activity were observed. Adolescents who were ‘no longer depressed’ (RR 1.53, 95% CI 1.07 to 2.20) or ‘remained depressed’ (RR 1.78, 95% CI 1.12 to 2.83) at 6 months were more likely to be from the intervention borough. For well-being, there was no association between boroughs and change in well-being between baseline and the 6-month follow-up. At 18 months’ follow-up, adolescents who ‘remained depressed’ (RR 1.93, 95% CI 1.01 to 3.70) were more likely to be from the intervention borough than from comparison boroughs. No associations were observed for well-being at 18 months. There was limited evidence of change for parental mental health and well-being. The qualitative study found that residents generally welcomed the unexpected chance to live in a cleaner, safer and more unified environment. The findings suggested that the Games temporarily alleviated certain stressors in the social and physical environment. Overall, the Games lessened participants’ sense of social exclusion and appeared to generate a sense of inclusion and respite, even if this was only temporary. Study limitations include the potential for adolescents to not be assigned the correct level of exposure to urban regeneration and the effect of reductions in central and local public budgets owing to the UK Government’s deficit reduction programme.

Conclusions

This study provided the highest quality data to date on the short- and medium-term social and health impacts of sporting mega-events. We found limited evidence that the London 2012 Olympic and Paralympic Games had a positive effect on adolescent or parental physical activity, mental health or well-being.
