Place effects on health: how can we conceptualise, operationalise and measure them?

Neighborhood Deprivation and Smoking in France: The TEMPO Cohort Study

BACKGROUND

Smoking prevalence follows a socioeconomic gradient. In France, although overall smoking rates have declined, the prevalence of daily smoking remains high among individuals with the lowest socioeconomic position (SEP), especially during the Covid-19 pandemic. Literature suggests that the level of neighborhood deprivation is also associated with smoking status, and this association might vary by SEP. However, the literature is mostly cross-sectional and limited in France.

AIM

To determine the association of neighborhood deprivation on smoking, and the role of individual SEP within this association.

METHODS

Using data from the French TEMPO cohort study, we conducted generalized estimating equation models to estimate the relationship between smoking status, tertiles of the French Deprivation Index (FDEP), and individual SEP, measured by education level.

RESULTS

The analysis was conducted on 837 participants with an average age of 31.2 years. The results of the generalized estimating equation model indicated no overall association between the FDEP and smoking, however our stratified analysis showed that those with low education residing in the highest deprivation tertile had, on average, 2.76 times greater odds of being smokers (95% CI 1.29-5.93) compared to those in the lowest deprivation tertile. Sensitivity analyses weighted by propensity scores to account for selective mobility showed consistent results.

CONCLUSION

In the first study of its nature in France, we found an association between neighborhood deprivation and smoking status for those with a low SEP. However, further research with a more representative cohort and a longer follow-up is needed.

Activity Space Mapping and Pre-Exposure Prophylaxis Uptake Among Gay, Bisexual, and Other Sexual Minority Men in Small Cities and Towns in the United States

In the US, gay, bisexual, and other sexual minoritized men (GBSMM) remain disproportionately impacted by HIV, and continue to experience unmet needs for pre-exposure prophylaxis (PrEP). A growing body of literature has underscored the need to consider the geographic factors of HIV prevention, particularly beyond administrative boundaries and towards localized spaces that influence the accessibility and utilization of health-promoting resources. Therefore, the purpose of this study is to examine the associations of driving times from activity spaces to PrEP offering facilities and individual PrEP uptake. A total of 218 GBSMM (ages 18-34) from Connecticut and Georgia were sampled from a longitudinal cohort study. We used the getis-ord-gi statistic to examine the spatial clustering of PrEP offering facilities, and generalized estimating equations (GEE) and post-hoc moderation analyses to explore the state interactions on driving time and PrEP uptake. Our main findings suggest that for participants in Connecticut, state of residence was a significant moderator on driving time and ever hearing of PrEP and ever taking PrEP. Whereas for participants in Georgia, state of residence moderated the likelihood of returning to activity spaces of participants in both Connecticut and Georgia on PrEP uptake. These findings provide important direction for geographic inequities on PrEP use, but also a pragmatic method for co-creating and re-imagining place-health research. These results also offer an avenue to leverage the dynamic nuance of activity spaces as indicators to inform structural interventions for PrEP that are more equitable for GBSMM in small cities and towns in the U.S.

Social Inequities in Cardiovascular Disease Risk Factors at Multiple Levels Persist Among Mothers in Texas

The life stage between the ages of 30-45 years for women is critical, given the competing demands of occupational advancement, intimate partner relationships, and childcare responsibilities. Cardiovascular disease (CVD) is the leading cause of death among women in the US, which is experienced inequitably by race/ethnicity/nativity and socioeconomic status and is embedded within geographic contexts. The objective of the current study was to examine social inequities in pre-pregnancy risk factors for cardiovascular disease. We analyzed 16 years of geocoded natality data in Texas (N = 2,089,588 births between 2005 and 2020 to mothers aged 30-45 years) linked with census tract- and county-level data. Dependent variables included pre-pregnancy diabetes, hypertension, obesity, and smoking. Independent variables included individual-level race/ethnicity/nativity and educational attainment, tract-level poverty and racial/ethnic concentrations, and county-level urban/rural status, with controls for other sociodemographic characteristics and time trend. Two-level, random intercept hierarchical generalized logistic models were used to estimate associations and model fit. Significant social inequities at the individual-, tract-, and county-levels in each risk factor were found. For example, tract-level variables had substantial and significant association with the four CVD risk factors, ranging from 13% to 72% higher odds in adjusted models. For all four risk factors, the more rural the county of residence was, the higher the odds of having the risk factor (24% to 256% higher odds). Individual-level social inequalities by race/ethnicity/nativity (ORs ranging from 0.04 to 2.12) and education (ORs ranging from 1.25 to 5.20) were also observed. Enhancing our understanding of this important period of life may enable policy and interventions to better support women through this critical life stage.

Neighborhood intergenerational mobility and population health inequality: Spatial dependency and heterogeneity

Health inequity represents a significant social injustice with major policy implications. This study examines the role of neighborhood intergenerational mobility (IM)-defined as the extent to which children within a specific neighborhood can achieve better socioeconomic outcomes than their parents-in shaping population health, addressing widening health inequalities. We propose that neighborhood IM is positively associated with population health, moderated by spatial dependency and heterogeneity. Analyzing over 69,000 census tracts in the contiguous United States using spatially-lagged X models, we find that neighborhood IM is positively associated with health status. The positive relationship weakens in neighborhoods surrounded by neighborhoods with higher levels of IM and strengthens in neighborhoods surrounded by neighborhoods with lower levels of IM. It also weakens in more advantaged environments-characterized by higher socioeconomic indicators, better built environment features, and more favorable natural environment conditions-and strengthens in less advantaged environments with poorer socioeconomic, built, and natural conditions. Our findings underscore the critical role of neighborhood context and heterogeneity in shaping the effects of social determinants on health, suggesting that policymakers should prioritize resources for disadvantaged neighborhoods with lower IM, particularly those surrounded by similarly low-IM areas, to mitigate health disparities more effectively. Our study provides new insights into the role of neighborhood IM in population health and demonstrates the value of geographic approaches for understanding and mitigating health disparities.

Leveraging context-specific behavioral economic principles to enable patients to change their physical activity patterns

This study explores how context-specific behavioral economic principles could be employed to tailor interventions to support patients' efforts to modify day-to-day routines. Using adapted geo-ethnography techniques, interviews collected in-depth descriptions about facilitators and barriers to physical activity (PA), and contexts influencing decisions about day-to-day activities. Data were analyzed using the COM-B model for behavior change and MINDSPACE behavioral economic principles as coding frameworks. Twenty-nine patients (19 men, 10 women) aged 50-79 participated. Findings indicate patients were motivated and capable of increasing PA but were challenged to identify opportunities to adapt day-to-day routines for increasing PA. Patients described disrupting default routines, increasing commitments, changing the messenger, and introducing incentives as potentially useful behavioral economic principles to improve day-to-day decisions about increasing PA. Patients had insight into potential behavioral economic principles, although they were not previously educated, and were valuable partners in developing research and clinic-based behavioral economic intervention strategies.

Regional variations in healthcare in people living with dementia in Germany: protocol for a mixed-methods study

INTRODUCTION

Care for people living with dementia is both important and complex, and there is evidence of large regional variations in the quality of care. This study protocol describes design, methods and objectives of an investigation of regional variations in the utilisation, the quality and the costs of care for people living with dementia in Germany.

METHODS AND ANALYSIS

An exploratory, naturalistic, mixed-methods study is being conducted with three modules: Module A: A quantitative analysis of claims data of statutory health insurance will be conducted to investigate regional variations in the utilisation and costs of care. Module B: In selected regions of interest that deviate significantly from the average in terms of utilisation in Module A, the quality of care and patient characteristics, variations and possible causes of these variations in care will be examined in more detail using quantitative and qualitative assessments. Module C: The claims and primary data from modules A and B will be combined, synthesised and evaluated to elicit recommendations for regional healthcare using a participatory consensus method.

ETHICS AND DISSEMINATION

The study is overseen by the German Alzheimer's Association. The study's ethics and data protection plan was approved by the data and ethics committee of the leading university, Brandenburg Medical School Theodor Fontane (reference number: 152092023-BO-E) as well as the data committee of the three participating health insurances. Dissemination plans include dissemination of our main results to the general public, people affected, the scientific community and funding-, policy- and decision makers. Study outcomes and conclusions will be published on our own and the funder's websites, through presentations at conferences and in scientific journals. The funder ensures dissemination of main study results and recommendations for action to relevant organisations and institutions. Publication of the study's main results is planned within 6 months of the study's conclusion.

Racial/Ethnic Differences and Effects of Clinical/Socioeconomic Factors on Time from Diagnosis to Treatment in Pancreatic Cancer

PURPOSE

Five-year survival for pancreatic adenocarcinoma (PDAC) is < 10% but can vary by a patient's race, socioeconomic status (SES), and the factors related to the neighborhood where a patient lives (nSES) . Prolonged time from diagnosis to first treatment (T2T) is another important disparity indicator. Here, we examined the effect of race, nSES, and patient-level clinical factors on T2T and survival in metastatic PDAC (mPDAC) patients.

METHODS

Patients with mPDAC treated at an academic cancer center between 2010 and 2018 (n = 334) were evaluated for nSES measures related to racial concentration, neighborhood deprivation, stability, immigration status, and transportation access from the US Census. We assessed and reported the effects of nSES and patient-level variables (age, race, gender, Charlson Comorbidity Index (CCI), etc.) on T2T and survival using univariate and multivariate Cox proportional hazards regression, hazard ratios (HR), confidence intervals (CI).

RESULTS

82.9% of the patients were White; 17.1% were Black. Median T2T was 26 days with no significant difference in T2T and survival by race. In multivariable models, no nSES variables were significantly associated with T2T. T2T did not significantly impact survival; however, receipt of chemotherapy (HR = 0.14 [95% CI = 0.06, 0.30]) was associated with better survival outcomes.

CONCLUSION

Among patients with mPDAC, T2T was not associated with race/ethnic disparities or survival in a mostly White, high SES population treated at a comprehensive cancer center. Future investigations into pancreatic cancer disparities may be warranted in other hospital settings and in larger, more diverse study samples.

How could 20-minute neighbourhoods impact health and health inequalities? A policy scoping review

BACKGROUND

'Twenty-minute neighbourhoods' (or variations, such as 15-minute cities) are receiving increasing policy attention with anticipated impacts on population health (inequalities) outcomes alongside sustainability improvements. Yet, factors contributing to possible health impacts are not well understood. This scoping review aimed to identify proposed and evidenced pathways to health (inequality) outcomes from international policy plans.

METHODS

We first identified relevant academic literature, searching Scopus, (Ovid) Medline and Embase databases. A second search aimed to identify local or national planning or policy documents on government websites and related organisations. We followed a snowball search strategy to retrieve examples identified from the academic literature search and from the C40 cities network. These policy documents were our primary target for extraction, and we extracted and analysed by individual place. Pathways to health and health inequality outcomes identified in these documents were inductively coded thematically. We used Sankey diagrams to visually aggregate the thematic codes for each place relating to pathways to health outcomes and social determinants (mechanisms).

RESULTS

In total, 36 places across 17 countries were included, described across 96 academic articles, policy plans and reports. While different health improvement outcomes were included as a goal in nearly all policy plans, most frequently references were to health in general rather than specific health outcomes. Pathways to health were discussed in numerous policy plans across three overarching themes: proximity, place redesign, and environmental action. Proximity pathways were most frequently outlined as the means to achieve health outcomes, with active travel acting through increased physical activity/reduced obesity as the most frequent individual pathway. However, few plans specified what would actually be implemented in practice to achieve the increased proximity to services. Health inequalities were only mentioned by six places specifically, although nearly half of all places mentioned broader inequality aims (e.g., poverty reduction). Possible unintended consequences to health inequalities also received some attention, for example through displacement of residents.

DISCUSSION

Pathways to assumed health (inequality) outcomes require better specification and evidence. Health inequalities are particularly under-explored, and scenario modelling might provide a means to explore the dynamic aspects necessary to examine these important outcomes pre-implementation.

Association between social cohesion and food insecurity among adults living in a healthcare region in southern Brazil

BACKGROUND

Food insecurity (FI) has grown worldwide in recent years, especially in developing countries. Studies have shown that aspects of the social environment, such as social cohesion in the neighborhood, may be associated with FI; however, this topic has yet to be explored, in Brazil. This study aims to verify the association between aspects of the perceived social environment of the neighborhood (social cohesion) and FI.

METHODS

This is a cross-sectional study with adults and elderly individuals (n = 400) residing in a healthcare region in Porto Alegre, Rio Grande do Sul (Brazil). The sample is selected proportionally from areas of higher and lower socioeconomic status, and data are collected through household interviews. The presence of FI is assessed using the Brazilian Food Insecurity Scale (short version). The perception of the neighborhood regarding social cohesion is obtained using a questionnaire validated for the Brazilian population. Poisson regression with robust variance was used to estimate the crude and adjusted prevalence ratios (PRs) and their respective 95% confidence intervals (95% CIs).

RESULTS

Individuals with more positive perceptions of social cohesion in the neighborhood are less likely to experience FI than those with less positive perceptions [PR = 0.73; 95% CI (0.55-0.97)], after adjustments.

CONCLUSIONS

The community social environment is independently associated with FI and may have characteristics that positively influence the probability of individuals experiencing FI. Interventions at the community level are necessary to address FI.

Association between snack intake behaviors of children and neighboring women: A population-based cross-sectional analysis with spatial regionalization

Background

Accumulated evidence indicates that neighborhood environments affect children's health behaviors. However, measuring neighborhood environments remains challenging because there exist strengths and weaknesses both in objective and perceived environment measures. Drawing on a recent conceptual model of how environment, perception, and behavior interact, we hypothesized that neighbors' behavioral similarities indicate the combined influence of physical and social environmental opportunities on specific behaviors. We then examined how these similarities (i.e. the behavioral tendencies of children's adult neighbors) relate to children's obesogenic dietary behaviors.

Methods

We used data for 2275 women and 821 elementary schoolchildren from a 2012-2013 population-based survey in greater Tokyo, Japan. Snack intake was defined as the total consumption of various types of snacks, estimated using a validated self-administered diet history questionnaire. Spatial regionalization, a type of spatial clustering, was used to empirically identify segments that could effectively differentiate regional variation in women's snack intake behaviors. We conducted multiple regression analysis to assess the cross-sectional association between children's snack intake and the mean snack intake of neighborhood women, adjusting for mother's intake.

Results

A 1-g increase in the mean snack intake of neighborhood women was associated with a 0.23-g (95% confidence interval: 0.00-0.45) increase in children's intake, while a 1-g increase in mother's intake was associated with a 0.34-g (95% confidence interval: 0.26-0.41) increase in children's intake.

Discussion

The results suggest that the out-of-home physical and social neighborhood environments may have non-ignorable associations with children's dietary behaviors by offering behavioral opportunities in addition to maternal influence.

'Why do GPs want to come here?': residents' intentions to register with new-coming GPs in a disadvantaged neighbourhood in Copenhagen with a GP shortage: a qualitative study

OBJECTIVE AND INTERVENTION

To explore contextual factors influencing residents' intentions to register with one of the new-coming GPs established as a result of a municipally driven GP coverage intervention in a disadvantaged neighbourhood in Copenhagen with a GP shortage.

DESIGN

A qualitative study design informed by realist methodology was used to conduct the study. Data were obtained through a survey with residents (n = 67), two focus group interviews with residents (n = 21), semi-structured interviews with the project- and local community stakeholders (n = 8) and participant observations in the neighbourhood. The analysis was carried out through systematic text condensation and interpreted and structured by Pawson's layers of contextual influence (infrastructural and institutional). The concept of collective explanations by Macintyre et al. and Wacquant's framework of territorial stigmatisation were applied to analyse and discuss the empirical findings.

SUBJECT AND SETTING

Residents from five local community organisations in a disadvantaged neighbourhood in Copenhagen.

MAIN OUTCOME MEASURES

Infrastructural and institutional contextual factors influencing residents' intentions to register with one of the new-coming GPs.

RESULTS

Infrastructural contextual factors included the national shortage of GPs, the administration fee for registering with a new GP, and the neighbourhood's reputation as being feared and unattractive for GPs to establish themselves. Institutional contextual factors included mistrust towards municipal authorities and the new-coming GPs shared by many residents, the duration without a local GP, GPs' reputation and a perceived lack of information about the GP coverage intervention, and an experience of not being involved.

CONCLUSION AND IMPLICATION

Infrastructural and institutional contextual factors influenced residents' intentions to register with one of the new-coming GPs. The findings will be helpful in adjusting, implementing, and disseminating the intervention and developing and implementing future complex interventions in disadvantaged neighbourhoods.

[Association between community violence and the risk of food insecurity in a capital city in Southern Brazil]

Food insecurity and urban violence are among the main public health problems in Brazil, with approximately half of the population having impaired access to food, in addition to most individuals having already experienced some violent event in their neighborhood. Studies have shown that violence in the neighborhood can be associated with food insecurity, however, in Brazil, this topic is little explored. This study aimed to verify the association between the perception of violence in the neighborhood and the risk of food insecurity. This study has a cross-sectional design, having been carried out with adults and older adults (n = 400) living in a health district of the city of Porto Alegre, Rio Grande do Sul State. A stratified sampling method was adopted. Data was collected by household interviews. The presence of risk of food insecurity and the perception of violence in the community were evaluated using instruments validated for the Brazilian population. Poisson regression with robust variance was used to estimate the crude and adjusted prevalence ratios (PR) and their respective 95% confidence intervals (95%CI). Individuals that perceived their neighborhood as violent were more likely to be at risk of food insecurity (PR = 1.35; 95%CI: 1.04-1.77). Perception of neighborhood violence is associated with risk of food insecurity, independently, after adjusting for potential confounders. Issues related to the social environment, especially in relation to perceived violence, must be considered in the creation of public policies and actions against food insecurity.

Development of Composite Measures of Neighborhood Economic Factors for Use in Spinal Cord Injury Outcomes Studies: A Spinal Cord Injury Model Systems Database Study

OBJECTIVE

To develop composite measures of neighborhood economic factors for use with the national Spinal Cord Injury Model Systems (SCIMSs) database in cross-sectional and longitudinal investigations of the social determinants of health.

DESIGN

Secondary data analysis of administrative data from the 2009, 2014, and 2019 American Community Survey (ACS) 5-year estimates and survey data collected for the SCIMS database.

SETTING

Community.

PARTICIPANTS

The validity of the neighborhood economic measures developed from the ACS data was tested with a sample of SCIMS participants who completed a follow-up interview between 2017 and 2021 (N=8,130). The predictive validity of the neighborhood measures was assessed with a subsample of cases with complete data on the outcome and covariate measures (N=6,457).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

A binary measure of self-rated health status (1=poor/fair health; 0=good/very good/excellent).

RESULTS

A combination of panel review and data reduction techniques yielded 2 distinct measuring neighborhood socioeconomic status (SES) and neighborhood socioeconomic disadvantage that were validated using 3 waves of ACS data and the SCIMS data. The odds of reporting poor health were lower among people living in moderate- and high-SES neighborhoods and highest among people living in moderately and highly disadvantaged neighborhoods. The negative association between neighborhood SES and poor health was fully attenuated by differences in participants' individual demographic and economic characteristics whereas the positive association between neighborhood disadvantage and poor health persisted after adjusting for individual differences.

CONCLUSIONS

The two composite measures of neighborhood economic factors developed by this study are robust in samples from different periods of time and valid for use with the SCIMS database. Future investigations conducting surveillance of the needs of the SCI population using this resource may consider using these measures to assess the effect of the social determinants of health in outcomes after SCI.

Social epidemiology of urban COVID-19 inequalities in Latin America and Canada

BACKGROUND

The COVID-19 pandemic has spread through pre-existing fault lines in societies, deepening structural barriers faced by precarious workers, low-income populations, and racialized communities in lower income sub-city units. Many studies have quantified the magnitude of inequalities in COVID-19 distribution within cities, but few have taken an international comparative approach to draw inferences on the ways urban epidemics are shaped by social determinants of health.

METHODS

Guided by critical epidemiology, this study quantifies sub-city unit-level COVID-19 inequalities across eight of the largest metropolitan areas of Latin America and Canada. Leveraging new open-data sources, we use concentration indices to quantify income- and vulnerability-related inequalities in incidence, test positivity, and deaths over the first 125 weeks of the pandemic between January 2020 and May 2022.

RESULTS

Our findings demonstrate that incidence, deaths, and test positivity are all less concentrated in low-income sub-city units than would be expected, with incidence ranging concentration in lower income neighbourhoods in Toronto (CI = -0.07) to concentration in higher income neighbourhoods in Mexico City (CI = 0.33). Drawing on relevant studies and evaluations of data reliability, we conclude that the best available public surveillance data for the largest cities in Latin America are likely not reliable measures of the true COVID-19 disease burden. We also identify recurring trends in the evolution of inequalities across most cities, concluding that higher income sub-city units were frequent early epicentres of COVID-19 transmission across the Latin America and Canada.

CONCLUSIONS

Just as critical epidemiology points to individuals biologically embodying the material and social conditions in which we live, it may be just as useful to think of cities reifying their material and social inequities in the form of sub-city unit-level infectious disease inequities. By shifting away from a typical vulnerability-based social determinants of health frame, policymakers could act to redress and reduce externalities stemming from sub-city unit-level income inequality through redistributive and equity-promoting policies to shift the centre of gravity of urban health inequalities before the next infectious disease epidemic occurs.

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.

Early-life air pollution and green space exposures as determinants of stunting among children under age five in Sub-Saharan Africa

BACKGROUND

Childhood malnutrition is a major public health issue in Sub-Saharan Africa (SSA) and 61.4 million children under the age of five years in the region are stunted. Although insight from existing studies suggests plausible pathways between ambient air pollution exposure and stunting, there are limited studies on the effect of different ambient air pollutants on stunting among children.

OBJECTIVE

Explore the effect of early-life environmental exposures on stunting among children under the age of five years.

METHODS

In this study, we used pooled health and population data from 33 countries in SSA between 2006 and 2019 and environmental data from the Atmospheric Composition Analysis Group and NASA's GIOVANNI platform. We estimated the association between early-life environmental exposures and stunting in three exposure periods - in-utero (during pregnancy), post-utero (after pregnancy to current age) and cumulative (from pregnancy to current age), using Bayesian hierarchical modelling. We also visualise the likelihood of stunting among children based on their region of residence using Bayesian hierarchical modelling.

RESULTS

The findings show that 33.6% of sampled children were stunted. In-utero PM2.5 was associated with a higher likelihood of stunting (OR = 1.038, CrI = 1.002-1.075). Early-life exposures to nitrogen dioxide and sulphate were robustly associated with stunting among children. The findings also show spatial variation in a high and low likelihood of stunting based on a region of residence.

IMPACT STATEMENT

This study explores the effect of early-life environmental exposures on child growth or stunting among sub-Saharan African children. The study focuses on three exposure windows - pregnancy, after birth and cumulative exposure during pregnancy and after birth. The study also employs spatial analysis to assess the spatial burden of stunted growth in relation to environmental exposures and socioeconomic factors. The findings suggest major air pollutants are associated with stunted growth among children in sub-Saharan Africa.

Time-Use Sequences: A Mixed-Methods Study Exploring How, When, and Where Spatiotemporal Patterns of Everyday Routines Can Strengthen Public Health Interventions

BACKGROUND

Behavior change interventions are critical for the secondary prevention of cardiovascular disease and for reducing the risk of a repeat event or mortality. However, the effectiveness of behavior change interventions is challenged by a lack of spatiotemporal contexts, limiting our understanding of factors that influence the timing and location in which day-to-day activities occur and the maintenance of behavior change. This study explored how behavior change interventions could incorporate spatiotemporal contexts of patient activities for modifying behaviors.

METHODS

A mixed-methods approach with adapted geo-ethnography techniques was used to solicit detailed descriptions of patients' day-to-day routines, including where, when, and how patients spend time. Data were gathered from patients in one cardiac intervention program in Nova Scotia, Canada, from June to September 2021.

RESULTS

A total of 29 individuals (19 men and 10 women) between the ages of 45 and 81 and referred to the program after a cardiac event participated. The results show three key findings: (1) most patients exceeded the minimum guidelines of 30 min of daily physical activity but were sedentary for long periods of time, (2) patient time-use patterns are heterogenous and unique to contexts of individual space-time activity paths, and (3) time-use patterns reveal when, where, and how patients spend significant portions of time and opportunities for adapting patients' day-to-day health activities.

CONCLUSIONS

This study demonstrates the potential for interventions to integrate tools for collecting and communicating spatial and temporal contexts of patient routines, such as the types of activities that characterize how patients spend significant portions of time and identification of when, where, and how to encourage health-promoting changes in routine activities. Time-use patterns provide insight for tailoring behavior change interventions so that clinic-based settings are generalizable to the contexts of where, when, and how patient routines could be adapted to mitigate cardiovascular risk factors.

Co-creating community wellbeing initiatives: what is the evidence and how do they work?

BACKGROUND

Addressing wellbeing at the community level, using a public health approach may build wellbeing and protective factors for all. A collaborative, community-owned approach can bring together experience, networks, local knowledge, and other resources to form a locally-driven, place-based initiative that can address complex issues effectively. Research on community empowerment, coalition functioning, health interventions and the use of local data provide evidence about what can be achieved in communities. There is less understanding about how communities can collaborate to bring about change, especially for mental health and wellbeing.

METHOD

A comprehensive literature search was undertaken to identify community wellbeing initiatives that address mental health. After screening 8,972 titles, 745 abstracts and 188 full-texts, 12 exemplar initiatives were identified (39 related papers).

RESULTS

Eight key principles allowed these initiatives to become established and operate successfully. These principles related to implementation and outcome lessons that allowed these initiatives to contribute to the goal of increasing community mental health and wellbeing. A framework for community wellbeing initiatives addressing principles, development, implementation and sustainability was derived from this analysis, with processes mapped therein.

CONCLUSION

This framework provides evidence for communities seeking to address community wellbeing and avoid the pitfalls experienced by many well-meaning but short-lived initiatives.

Structural changes in a Danish social housing area: The impact of forced permanent rehousing on contact frequency with general practitioner and use of antidepressants

There is a lack of knowledge about the health consequences of politically initiated forced permanent rehousing (FPR) of residents in social housing areas. This study investigates if FPR is associated with the contact frequency with general practitioner (GP) and the proportion of residents who use antidepressants. The study included 432 rehoused residents matched 1:2 with remaining residents and residents from a comparable neighbouring area without exposure to rehousing. For GP contact frequency, we conducted a difference-in-difference analysis while the proportion of residents who used antidepressants was investigated through descriptive statistics. We found high GP contact frequency in the three groups, but no significant differences. Further, we found a low proportion of residents who used antidepressants in all groups, but a small increase from baseline to follow-up. Our results thus suggest that FPR neither affected the rehoused residents' GP contact frequency nor the proportion who used antidepressants.

Contextual Deprivation, Race and Ethnicity, and Income in Air Pollution and Cardiovascular Disease

Importance

Socioeconomically disadvantaged subpopulations are more vulnerable to fine particulate matter (PM2.5) exposure. However, as prior studies focused on individual-level socioeconomic characteristics, how contextual deprivation modifies the association of PM2.5 exposure with cardiovascular health remains unclear.

Objective

To assess disparities in PM2.5 exposure association with cardiovascular disease among subpopulations defined by different socioeconomic characteristics.

Design, Setting, and Participants

This cohort study used longitudinal data on participants with electronic health records (EHRs) from the All of Us Research Program between calendar years 2016 and 2022. Statistical analysis was performed from September 25, 2023, through February 23, 2024.

Exposure

Satellite-derived 5-year mean PM2.5 exposure at the 3-digit zip code level according to participants' residential address.

Main Outcome and Measures

Incident myocardial infarction (MI) and stroke were obtained from the EHRs. Stratified Cox proportional hazards regression models were used to estimate the hazard ratio (HR) between PM2.5 exposure and incident MI or stroke. We evaluated subpopulations defined by 3 socioeconomic characteristics: contextual deprivation (less deprived, more deprived), annual household income (≥$50 000, <$50 000), and race and ethnicity (non-Hispanic Black, non-Hispanic White). We calculated the ratio of HRs (RHR) to quantify disparities between these subpopulations.

Results

A total of 210 554 participants were analyzed (40% age >60 years; 59.4% female; 16.7% Hispanic, 19.4% Non-Hispanic Black, 56.1% Non-Hispanic White, 7.9% other [American Indian, Asian, more than 1 race and ethnicity]), among whom 954 MI and 1407 stroke cases were identified. Higher PM2.5 levels were associated with higher MI and stroke risks. However, disadvantaged groups (more deprived, income <$50 000 per year, Black race) were more vulnerable to high PM2.5 levels. The disparities were most pronounced between groups defined by contextual deprivation. For instance, increasing PM2.5 from 6 to 10 μg/m3, the HR for stroke was 1.13 (95% CI, 0.85-1.51) in the less-deprived vs 2.57 (95% CI, 2.06-3.21) in the more-deprived cohort; 1.46 (95% CI, 1.07-2.01) in the $50 000 or more per year vs 2.27 (95% CI, 1.73-2.97) in the under $50 000 per year cohort; and 1.70 (95% CI, 1.35-2.16) in White individuals vs 2.76 (95% CI, 1.89-4.02) in Black individuals. The RHR was highest for contextual deprivation (2.27; 95% CI, 1.59-3.24), compared with income (1.55; 95% CI, 1.05-2.29) and race and ethnicity (1.62; 95% CI, 1.02-2.58).

Conclusions and Relevance

In this cohort study, while individual race and ethnicity and income remained crucial in the adverse association of PM2.5 with cardiovascular risks, contextual deprivation was a more robust socioeconomic characteristic modifying the association of PM2.5 exposure.

Associations between neighbourhood deprivation, ethnicity and maternal health outcomes in England: a nationwide cohort study using routinely collected healthcare data

BACKGROUND

In the United Kingdom, pregnant women who live in the most deprived areas have two times the risk of dying than those who live in the least deprived areas. There are even greater disparities between women from different ethnic groups. The aim of this study was to investigate the role of area-based deprivation and ethnicity in the increased risk of severe maternal morbidity (SMM), in primiparous women in England.

METHODS

A retrospective nationwide population study was conducted using English National Hospital Episode Statistics Admitted Patient Care database. All primiparous women were included if they gave birth in an National Healthcare Service (NHS) hospital in England between 1 January 2016 and 31 December 2021. Logistic regression was used to examine the relative odds of SMM by Index of Multiple Deprivation and ethnicity, adjusting for age and health behaviours, medical and psychological factors.

RESULTS

The study population comprised 1 178 756 primiparous women. Neighbourhood deprivation increased the risk of SMM at the time of childbirth. In the fully adjusted model, there was a linear trend (p=0.001) between deprivation quintile and the odds of SMM. Being from a minoritised ethnic group also independently increased the risk of SMM, with black or black British African women having the highest risk, adjusted OR 1.84 (95% CI 1.70 to 2.00) compared with white women. There was no interaction between deprivation and ethnicity (p=0.49).

CONCLUSION

This study has highlighted that neighbourhood deprivation and ethnicity are important, independently associated risk factors for SMM.

Scoping review of practice-focused resources to support the implementation of place-based approaches

ISSUE ADDRESSED

There is increasing interest across public health research, policy, and practice in place-based approaches to improve health outcomes. Practice-focused resources, such as grey literature, courses and websites, are utilised by practitioners to support the implementation of place-based approaches.

METHODS

A detailed search of two search engines: Google and DuckDuckGo to identify free practice-focused resources was conducted.

RESULTS

Forty-one resources met inclusion criteria, including 26 publications, 13 web-based resources and two courses. They were mainly focused on collaboration, developed by not-for-profit organisations, focused on a broad target audience, and supported people living with disadvantage. The publications we reviewed generally: clearly stated important information, such as the author of the publication; used their own evaluations, professional experience and other grey literature as supporting evidence; included specific, practical implementation strategies; and were easy to read.

CONCLUSIONS

Based on findings, we recommend that: (1) the development of resources to support evidence-informed practice and governance be prioritised; (2) resources clearly state their target audience and tailor communication to this audience; (3) resources draw on evidence from a range of sources; (4) resources continue to include practical implementation strategies supported by examples and (5) resource content be adaptable to different contexts (e.g., different settings and/or target populations). SO WHAT?: This is the first review of practice-focused resources to support the implementation of place-based approaches and the findings can be used to reduce duplication of efforts and inform future research, policy, and practice, particularly the refinement of existing resources and the development of future resources.

Contextual and individual inequalities in breast cancer screening participation and outcomes in Turin (North-West Italy)

Breast cancer incidence and screening participation exhibit an unequal distribution in the population. This study aims to investigate the impact of socioeconomic position (SEP) on three breast screening indicators (participation, recall, and cancer detection rates) among women aged 50-69 in the city of Turin between 2010 and 2019. The study also aims to determine whether contextual factors (deprivation index) or individual factors (educational level) have a greater influence. The data used in this study are sourced from the Turin Breast Screening Program (TBSP) and the Turin Longitudinal Study (TLS). To test the hypothesis and account for the hierarchical structure of the data, multilevel models were used. Both contextual and individual SEP were found to be associated with screening participation. Participation increased with higher levels of deprivation (odds ratio for most deprived: 1.13; 95% CI 1.11-1.16) and decreased with higher educational levels (OR for low educated: 1.37; 95% CI 1.34-1.40). Contextual SEP did not show any association with recall or cancer detection rates, but individual SEP had an impact. Women with lower educational levels had a statistically significant 19% lower odds of being recalled and a statistically significant 20% lower odds of being diagnosed with cancer. Additionally, immigrant women were less likely to participate in screening, be recalled, or receive a cancer diagnosis. Educational level consistently influenced the analyzed screening indicators, while contextual deprivation appeared to have less importance. It is likely that women living in less deprived areas and with higher education have greater access to opportunistic screening.

An innovative visual approach to the simultaneous study of two dimensions of progress in longevity: an application to French and German regions

BACKGROUND

Both enhancing life expectancy and decreasing inequalities in lifespan between social groups are significant goals for public policy. To date, however, methodological tools to study progress in both dimensions simultaneously have been lacking. There is also a consensus that absolute and relative inequalities in lifespan must be studied together.

METHODS

We introduce a novel graphical representation that combines national mortality rates with both absolute and relative measures of social inequality in mortality. To illustrate our approach, we analyze French and German data stratified by place of residence.

RESULTS

For all-age mortality, in France we find a steady pace of decline in both mortality and in regional inequalities in mortality over recent decades. In Germany, substantial progress was made in the 1990s, mostly driven by convergence between eastern and western Germany, followed by a period of slower progress. Age-specific analyses for Germany reveal a worrying divergence in regional trends at ages 35-74 in recent years, which is particularly pronounced among women.

CONCLUSION

Our novel visual approach offers a way to simultaneously examine two dimensions of progress in longevity, and facilitates meaningful comparisons between populations, even when their current mortality rates differ. The applied methods can be easily reproduced in any country for which long-term mortality series stratified by region, or any relevant socioeconomic characteristic, are available. It is useful for both scientific analysis and policy advice.

Place, displacement, and health-seeking behaviour among the Ugandan Batwa: A qualitative study

For many Indigenous Peoples, relationships to the land are inherent in identity and culture, and to all facets of health and wellbeing, physically, emotionally, psychologically, and spiritually. The Batwa are Indigenous Peoples of rural, southwest Uganda who have experienced tremendous social and economic upheaval, due to relatively recent forced displacement and land dispossession. This loss of physical connection to their ancestral lands has significantly impacted Batwa health, and also affected available healthcare options for Batwa. This exploratory study (1) identified and characterized factors that influence Batwa health-seeking behaviour, using acute gastrointestinal illness, a critical public health issue, as a focal point for analysis; and (2) explored possible intersections between the Batwa's connection to place-and displacement-and their health-seeking behaviour for acute gastrointestinal illness. Twenty focus group discussions, stratified by gender, were conducted in ten Batwa settlements in Kanungu District, Uganda and eleven semi-structured interviews were conducted with primary healthcare workers, community health coordinators, clinical officers, and development program coordinators. Qualitative data were thematically analyzed using a constant comparative method. Batwa identified several significant motivators to engage with Indigenous and/or biomedical forms of healthcare, including transition to life outside the forest and their reflections on health in the forest; 'intellectual access' to care and generational knowledge-sharing on the use of Indigenous medicines; and Batwa identity and way of life. These nuanced explanations for health-seeking behaviour underscore the significance of place-and displacement-to Batwa health and wellbeing, and its relationship to their health-seeking behaviour for acute gastrointestinal illness. As such, the results of this study can be used to inform healthcare practice and policy and support the development of a culturally- and contextually-appropriate healthcare system, as well as to reduce the burden of acute gastrointestinal illness among Batwa.

A comparison of content from across contemporary Australian population health surveys

OBJECTIVE

Associations between place and population health are of interest to researchers and policymakers. The objective of this paper is to explore, summarise and compare content across contemporary Australian geo-referenced population health survey data sets.

METHODS

A search for recent (2015 or later) population health surveys from within Australia containing geographic information from participants was conducted. Survey response frames were analysed and categorised based on demographic, risk factor and disease-related characteristics. Analysis using interactive Sankey diagrams shows the extent of content overlap and differences between population health surveys in Australia.

RESULTS

Thirteen Australian geo-referenced population health survey data sets were identified. Information captured across surveys was inconsistent as was the spatial granularity of respondent information. Health and demographic features most frequently captured were symptoms, signs and clinical findings from the International Statistical Classification of Diseases and Related Health Problems version 11, employment, housing, income, self-rated health and risk factors, including alcohol consumption, diet, medical treatments, physical activity and weight-related questions. Sankey diagrams were deployed online for use by public health researchers.

CONCLUSIONS

Identifying the relationship between place and health in Australia is made more difficult by inconsistencies in information collected across surveys deployed in different regions in Australia.

IMPLICATIONS FOR PUBLIC HEALTH

Public health research investigating place and health involves a vast and inconsistent patchwork of information within and across states, which may impact broad-scale research questions. The tools developed here assist public health researchers to identify surveys suitable for their research queries related to place and health.

When everyone's doing it: The relative effects of geographical context and social determinants of health on teen birth rates

Geographic disparities in teen birth rates in the U.S. persist, despite overall reductions over the last two decades. Research suggests these disparities might be driven by spatial variations in social determinants of health (SDOH). An alternative view is that "place" or "geographical context" affects teen birth rates so that they would remain uneven across the U.S. even if all SDOH were constant. We use multiscale geographically weighted regression (MGWR) to quantify the relative effects of geographical context, independent of SDOH, on county-level teen birth rates across the U.S. Findings indicate that even if all counties had identical compositions with respect to SDOH, strong geographic disparities in teen birth rates would still persist. Additionally, local parameter estimates show the relationships between several components of SDOH and teen birth rates vary over space in both direction and magnitude, confirming that global regression techniques commonly employed to examine these relationships likely obscure meaningful contextual differences in these relationships. Findings from this analysis suggest that reducing geographic disparities in teen birth rates will require not only ameliorating differences in SDOH across counties but also combating community norms that contribute to high rates of teen birth, particularly in the southern U.S. Further, the results suggest that if geographical context is not incorporated into models of SDOH, the effects of such determinants may be interpreted incorrectly.

Impactful co-design: Adult decision-makers' perspectives on actualising children's ideas for health-promoting neighbourhoods in Aotearoa New Zealand

Our study sought to understand adult decision-makers' views on what was important for actualising children's ideas using co-design, towards creating health-promoting local environments. Ten adult decision-makers, experienced in co-design with children aged 5-13 years in Aotearoa New Zealand, participated in individual interviews. We generated three themes (Empowering children within co-design; Being intentional about children's influence; Curating who is involved) using reflexive thematic analysis. Our themes informed a novel framework of 'impactful co-design' accompanied by a practical checklist for adult decision-makers (practitioners, policy-makers, and researchers). Study findings affirm co-designing local neighbourhoods as an inherently social and technical endeavour, advocate for greater consideration of inclusivity and cultural context, and highlight the need for co-design with children to include safety, empowerment, and evaluation. We position impactful co-design as one useful process to enact children's meaningful participation.

Subnational estimates of life expectancy at birth in India: evidence from NFHS and SRS data

BACKGROUND

Mortality estimates at the subnational level are of urgent need in India for the formulation of policies and programmes at the district level. This is the first-ever study which used survey data for the estimation of life expectancy at birth ([Formula: see text]) for the 640 districts from NFHS-4 (2015-16) and 707 districts from NFHS-5 (2019-21) for the total, male and female population in India.

METHODS

This study calculated annual age-specific mortality rates from NFHS-4 and NFHS-5 for India and all 36 states for the total, male and female population. This paper constructed the abridged life tables and estimated life expectancy at birth [Formula: see text] and further estimated the model parameters for all 36 states. This study linked state-specific parameters to the respective districts for the estimation of life expectancy at birth [Formula: see text]for 640 districts from NFHS-4 and 707 districts from NFHS-5 for the total, male and female population in India.

RESULTS

Findings at the state level showed that there were similarities between the estimated and calculated [Formula: see text] in most of the states. The results of this article observed that the highest [Formula: see text] varies in the ranges of 70 to 90 years among the districts of the southern region. [Formula: see text] falls below 70 years among most of the central and eastern region districts. In the northern region districts [Formula: see text] lies in the range of 70 years to 75 years. The estimates of life expectancy at birth [Formula: see text] shows the noticeable variations at the state and district levels for the person, male, and female populations from the NFHS (2015-16) and NFHS (2019-21). In the absence of age-specific mortality data at the district level in India, this study used the indirect estimation method of relating state-specific model parameters with the IMR of their respective districts and estimated [Formula: see text] across the 640 districts from NFHS-4 (2015-16) and 707 districts from NFHS-5 (2019-21). The findings of this study have similarities with the state-level estimations of [Formula: see text] from both data sources of SRS and NFHS and found the highest [Formula: see text] in the southern region and the lowest [Formula: see text] in the eastern and central region districts.

CONCLUSIONS

In the lack of [Formula: see text] estimates at the district level in India, this study could be beneficial in providing timely life expectancy estimates from the survey data. The findings clearly shows variations in the district level [Formula: see text]. The districts from the southern region show the highest [Formula: see text] and districts from the central and eastern region has lower [Formula: see text]. Females have higher [Formula: see text] as compared to the male population in most of the districts in India.

Women, water and access: inscribing gender power in and through a place

This paper explores the socio-cultural and gender-based dynamics associated with place values, and their implications for women's access to water through case studies of upland and riverine communities in southern Nigeria. We used a range of fieldwork methods including public meetings, focus group discussions, in-depth interviews, keen observations, key informants and other secondary sources. Our findings show that drinking water sources are a part of the many forms of visible material structures that embody and generate automatic reproduction of gender-based beliefs, attitudes, feelings and practices. The outcome of such practices affects men and women differently in relation to access, workload and capacity for hygiene and other socio-economic practices. In discussing access to essential public goods, social and economic capacities take priority focus over the impact of 'place values' either as standalone or intersectional elements. Research should be expanded to incorporate these elements and their intersectional perspectives in shaping access to water.

Do Publicly Funded Neighborhood Investments Impact Individual-Level Health-Related Outcomes? A Longitudinal Study of Two Neighborhoods in Pittsburgh, PA from 2011 to 2018

Research examining the relationship between a neighborhood's built-environment and resident health or health-related outcomes has largely either focused on static characteristics using a cross-sectional research design or focuses on the neighborhood in its entirety. Such an approach makes it difficult to understand how specific dynamic neighborhood characteristics are associated with individual well-being. In this analysis, we use longitudinal data from the Pittsburgh Research on Neighborhood Change and Health (PHRESH) studies to assess the relationship between publicly funded neighborhood investments occurring across seven years (2011-2018) on five health-related outcomes: food insecurity, stress, perceived neighborhood safety, neighborhood satisfaction, and dietary quality. We additionally utilize this dataset to determine whether the distance between an individual's place of residence and the investment, as measured at the neighborhood, 1 mile, and ½ mile level, effects the magnitude of associations. Using individual and year fixed effects models, we find that when measured at the neighborhood level, a one standard deviation increase in investments (about $130 million dollars) is associated with decreased food insecurity (-0.294 sd), increased safety (0.231 sd), and increased neighborhood satisfaction (0.201 sd) among adults who remain in the study for at least two waves of data collection. We also analyze specific investment types and find that commercial investments are largely driving the changes in food insecurity, safety, and neighborhood satisfaction, while business investments are correlated with the decrease in stress. We find no relationship between investments and dietary quality.

Evidence of COVID-19 fatalities in Swedish neighborhoods from a full population study

The COVID-19 pandemic has highlighted a debate about whether marginalized communities suffered the disproportionate brunt of the pandemic's mortality. Empirical studies addressing this question typically suffer from statistical uncertainties and potential biases associated with uneven and incomplete reporting. We use geo-coded micro-level data for the entire population of Sweden to analyze how local neighborhood characteristics affect the likelihood of dying with COVID-19 at individual level, given the individual's overall risk of death. We control for several individual and regional characteristics to compare the results in specific communities to overall death patterns in Sweden during 2020. When accounting for the probability to die of any cause, we find that individuals residing in socioeconomically disadvantaged neighborhoods were not more likely to die with COVID-19 than individuals residing elsewhere. Importantly, we do find that individuals show a generally higher probability of death in these neighborhoods. Nevertheless, ethnicity is an important explanatory factor for COVID-19 deaths for foreign-born individuals, especially from East Africa, who are more likely to pass away regardless of residential neighborhood.

Systematic review of best practices for GPS data usage, processing, and linkage in health, exposure science and environmental context research

Global Positioning System (GPS) technology is increasingly used in health research to capture individual mobility and contextual and environmental exposures. However, the tools, techniques and decisions for using GPS data vary from study to study, making comparisons and reproducibility challenging.

OBJECTIVES

The objectives of this systematic review were to (1) identify best practices for GPS data collection and processing; (2) quantify reporting of best practices in published studies; and (3) discuss examples found in reviewed manuscripts that future researchers may employ for reporting GPS data usage, processing and linkage of GPS data in health studies.

DESIGN

A systematic review.

DATA SOURCES

Electronic databases searched (24 October 2023) were PubMed, Scopus and Web of Science (PROSPERO ID: CRD42022322166).

ELIGIBILITY CRITERIA

Included peer-reviewed studies published in English met at least one of the criteria: (1) protocols involving GPS for exposure/context and human health research purposes and containing empirical data; (2) linkage of GPS data to other data intended for research on contextual influences on health; (3) associations between GPS-measured mobility or exposures and health; (4) derived variable methods using GPS data in health research; or (5) comparison of GPS tracking with other methods (eg, travel diary).

DATA EXTRACTION AND SYNTHESIS

We examined 157 manuscripts for reporting of best practices including wear time, sampling frequency, data validity, noise/signal loss and data linkage to assess risk of bias.

RESULTS

We found that 6% of the studies did not disclose the GPS device model used, only 12.1% reported the per cent of GPS data lost by signal loss, only 15.7% reported the per cent of GPS data considered to be noise and only 68.2% reported the inclusion criteria for their data.

CONCLUSIONS

Our recommendations for reporting on GPS usage, processing and linkage may be transferrable to other geospatial devices, with the hope of promoting transparency and reproducibility in this research.

A qualitative study of barriers and facilitators for health behavior change in low-income men with prostate cancer

PURPOSE

Low-income prostate cancer survivors, who typically have worse outcomes and greater all-cause mortality, often have poor health-promoting behaviors. Our objective was to assess perceived facilitators of and barriers to healthy behavior change by interviewing low-income men with prostate cancer who received no-cost treatment through a state-funded program.

METHODS

Between September 2021 and April 2022, we conducted semi-structured interviews with 19 men (ages 60-75). Purposive sampling was utilized from participants of a cohort of men with prostate cancer from low-income backgrounds. Interviews were recorded, transcribed, and then coded by the authors to generate salient themes via thematic analysis.

RESULTS

We found internal characteristics and structural characteristics that functioned independently and in concert to promote and/or hinder healthy behavior change. Internal characteristics such as motivations (prostate cancer diagnosis, self-perceptions, support system, and preferences) and determination, defined as level of motivation, drove behavior actualization. Structural characteristics that influenced behavior change included resources (access to food and opportunities for exercise) and social support.

CONCLUSIONS

These outcomes suggest that motivation and determination can serve as protective facilitators encouraging healthy behaviors despite structural barriers low-income prostate cancer survivors may face. However, motivations challenged by financial constraints were not sufficient to guide healthy behavior change. With this in mind, we recommend that interventions promoting healthy behavior change among this population should focus on identifying and strengthening internal assets such as motivations, self-perceptions, preferences, and support systems.

Lefebvre's production of space: Implications for nursing

In this paper, we argue that nurses need to be aware of how the production of space in specific contexts - including health care systems and research institutions - perpetuates marginalized populations' state of social otherness. Lefebvre's idea regarding spatial triad is mobilized in this paper, as it pertains to two-spirited, lesbian, gay, bisexual, trans and queer populations (2SLGBTQ*). We believe that nurses can create counter-spaces within health care systems and research institutions that challenge normative discourses. Lefebvre's work provides us the necessary tools to understand how various places or environments produce identities. In understanding Lefebvre's principles, we believe that nurses can play an essential role in creating counter-spaces, thereby instigating counter-institutional practices, for those who experience otherness.

Area-level Measures of the Social Environment: Operationalization, Pitfalls, and Ways Forward

People's mental health is intertwined with the social environment in which they reside. This chapter explores approaches for quantifying the area-level social environment, focusing specifically on socioeconomic deprivation and social fragmentation. We discuss census data and administrative units, egocentric and ecometric approaches, neighborhood audits, social media data, and street view-based assessments. We close the chapter by discussing possible paths forward from associations between social environments and health to establishing causality, including longitudinal research designs and time-series social environmental indices.

What is missing from how we measure and understand the experience of poverty and deprivation in population health analyses?

BACKGROUND

Explaining why some populations are healthier than others is a core task of epidemiology. Socioeconomic position (SEP), encompassing a broad range of exposures relating to economic circumstances, social class and deprivation, is an important explanation, but lacks a comprehensive framework for understanding the range of relevant exposures it encompasses.

METHODS

We reviewed existing literature on experiential accounts of poverty through database searching and the identification of relevant material by experts. We mapped relevant concepts into a complex systems diagram. We developed this diagram through a process of consultation with academic experts and experts with direct experience of poverty. Finally, we categorized concepts on the basis of whether they have previously been measured, their importance to the causal flow of the diagram, and their importance to those consulted, creating a list of priorities for future measurement.

RESULTS

There are a great many aspects of SEP which are not frequently measured or used in epidemiological research and, for some of these, work is needed to better conceptualize and develop measures. Potentially important missing aspects include stigma, social class processes, access to education, sense of lost potential, neighbourhoods, fairness and justice, emotional labour, masking poverty, being (in)visible, costs, and experiences of power.

CONCLUSIONS

Analyses seeking to understand the extent to which SEP exposures explain differences in the health of populations are likely to benefit from a comprehensive understanding of the range and inter-relationships between different aspects of SEP. More research to better conceptualize and measure these aspects is now needed.

Through Their Eyes: Youth Perspectives on Sexual and Reproductive Health Barriers and Facilitators in Baltimore, Maryland

PURPOSE

Youth face barriers to sexual and reproductive health (SRH). Few states require the delivery of comprehensive sex education in schools, and youth report challenges with accessing clinical care. We sought to identify youth's perceived barriers and facilitators to SRH in their communities.

METHODS

We utilized photovoice, a community-based participatory research methodology. Youth were recruited from high schools in Baltimore, Maryland. Participants were given a tutorial on Photovoice methodology and photography. In groups of 5-7 participants, youth brainstormed questions relevant to their perspective of SRH. Three months were allocated to taking photographs. Participants wrote brief narratives to accompany their photographs, and group level assessment was used for participants to comment on others' photographs. Participants discussed the narratives and comments, created themes, and generated action steps to address barriers to SRH. Further thematic analysis was conducted using NVivo.

RESULTS

There were 30 participants aged 14-19 years with 26 self-identifying as female and four nonbinary. Self-identified race/ethnicity included 50% Black/African American, 30% Asian American, and 20% White or Hispanic/Latino. Four domains emerged: desire for societal-level change, community-level change, peer-level change, and positive examples of SRH within their communities (e.g., gender-inclusive spaces and free menstrual products).

DISCUSSION

Youth photographs shed light on a strong desire for an improved school environment, in terms of safety, cleanliness, gender-inclusivity, menstrual product access, and SRH education.

Cohort profile: a large EHR-based cohort with linked pharmacy refill and neighbourhood social determinants of health data to assess heart failure medication adherence

PURPOSE

Clinic-based or community-based interventions can improve adherence to guideline-directed medication therapies (GDMTs) among patients with heart failure (HF). However, opportunities for such interventions are frequently missed, as providers may be unable to recognise risk patterns for medication non-adherence. Machine learning algorithms can help in identifying patients with high likelihood of non-adherence. While a number of multilevel factors influence adherence, prior models predicting non-adherence have been limited by data availability. We have established an electronic health record (EHR)-based cohort with comprehensive data elements from multiple sources to improve on existing models. We linked EHR data with pharmacy refill data for real-time incorporation of prescription fills and with social determinants data to incorporate neighbourhood factors.

PARTICIPANTS

Patients seen at a large health system in New York City (NYC), who were >18 years old with diagnosis of HF or reduced ejection fraction (<40%) since 2017, had at least one clinical encounter between 1 April 2021 and 31 October 2022 and active prescriptions for any of the four GDMTs (beta-blocker, ACEi/angiotensin receptor blocker (ARB)/angiotensin receptor neprilysin inhibitor (ARNI), mineralocorticoid receptor antagonist (MRA) and sodium-glucose cotransporter 2 inhibitor (SGLT2i)) during the study period. Patients with non-geocodable address or outside the continental USA were excluded.

FINDINGS TO DATE

Among 39 963 patients in the cohort, the average age was 73±14 years old, 44% were female and 48% were current/former smokers. The common comorbid conditions were hypertension (77%), cardiac arrhythmias (56%), obesity (33%) and valvular disease (33%). During the study period, 33 606 (84%) patients had an active prescription of beta blocker, 32 626 (82%) had ACEi/ARB/ARNI, 11 611 (29%) MRA and 7472 (19%) SGLT2i. Ninety-nine per cent were from urban metropolitan areas.

FUTURE PLANS

We will use the established cohort to develop a machine learning model to predict medication adherence, and to support ancillary studies assessing associates of adherence. For external validation, we will include data from an additional hospital system in NYC.

Strangers in a strange land: mapping household and neighbourhood associations with improved wellbeing outcomes in Accra, Ghana

Urban poverty is not limited to informal settlements, rather it extends throughout cities, with the poor and affluent often living in close proximity. Using a novel dataset derived from the full Ghanaian Census, we investigate how neighbourhood versus household socio-economic status (SES) relates to a set of household development outcomes (related to housing quality, energy, water and sanitation, and information technology) in Accra, Ghana. We then assess "stranger" households' outcomes within neighbourhoods: do poor households fare better in affluent neighbourhoods, and are affluent households negatively impacted by being in poor neighbourhoods? Through a simple generalized linear model we estimate the variance components associated with household and neighbourhood status for our outcome measures. Household SES is more closely associated with 13 of the 16 outcomes assessed compared to the neighbourhood average SES. Second, for 9 outcomes poor households in affluent areas fair better, and the affluent in poor areas are worse off. For two outcomes, poor households have worse outcomes in affluent areas, and the affluent have better outcomes in poor areas, on average. For three outcomes "stranger" households do worse in strange neighbourhoods. We discuss implications for mixed development and how to direct resources through households versus location-based targets.

How Societal Forces of Change Are Transforming Youth Physical Activity Promotion in North America

BACKGROUND

Climate change, increasing recognition of institutionalized discrimination, and the COVID-19 pandemic are large-scale, societal events (ie, forces of change) that affect the timing, settings, and modes of youth physical activity. Despite the impact that forces of change have on youth physical activity and physical activity environments, few studies consider how they affect physical activity promotion.

METHODS

The authors use 2 established frameworks, the ecological model of physical activity and the youth physical activity timing, how, and setting framework, to highlight changes in physical activity patterns of youth in North America that have resulted from contemporary forces of change.

RESULTS

North American countries-Canada, Mexico, and the United States-have faced similar but contextually different challenges for promoting physical activity in response to climate change, increasing recognition of institutionalized discrimination, and the COVID-19 pandemic. Innovative applications of implementation science, digital health technologies, and community-based participatory research methodologies may be practical for increasing and sustaining youth physical activity in response to these forces of change.

CONCLUSIONS

Thoughtful synthesis of existing physical activity frameworks can help to guide the design and evaluation of new and existing physical activity initiatives. Researchers, practitioners, and policymakers are encouraged to carefully consider the intended and unintended consequences of actions designed to respond to forces of change.

The Epidemiological and Economic Impact of COVID-19 in Kazakhstan: An Agent-Based Modeling

BACKGROUND

Our study aimed to assess how effective the preventative measures taken by the state authorities during the pandemic were in terms of public health protection and the rational use of material and human resources.

MATERIALS AND METHODS

We utilized a stochastic agent-based model for COVID-19's spread combined with the WHO-recommended COVID-ESFT version 2.0 tool for material and labor cost estimation.

RESULTS

Our long-term forecasts (up to 50 days) showed satisfactory results with a steady trend in the total cases. However, the short-term forecasts (up to 10 days) were more accurate during periods of relative stability interrupted by sudden outbreaks. The simulations indicated that the infection's spread was highest within families, with most COVID-19 cases occurring in the 26-59 age group. Government interventions resulted in 3.2 times fewer cases in Karaganda than predicted under a "no intervention" scenario, yielding an estimated economic benefit of 40%.

CONCLUSION

The combined tool we propose can accurately forecast the progression of the infection, enabling health organizations to allocate specialists and material resources in a timely manner.

A mixed methods exploration of injection drug use risk behaviors and place-based norms in Ukraine

INTRODUCTION

Despite global reductions in HIV incidence and significant investment in local harm reduction services, Ukraine continues to experience high HIV and HCV prevalence among people who inject drugs (PWID). Place-based factors and social norms affect drug use-related risk factors, but research has paid little attention to the relationship between drug use practices and place in Ukraine, including how these factors may contribute to or protect against HIV/HCV risk.

METHODS

This project used a sequential mixed methods design. Between March and August 2018, we interviewed 30 PWID in Dnipro, Ukraine. Participants completed a single in-depth interview in which they described where and with whom they lived; how they generated income; and where, when, how, and with whom they purchased and used drugs. Between May 2019 and March 2020, we recruited 150 PWID in Dnipro to complete a survey that was designed based on interview findings and consisted of three components: an activity space inventory, an egocentric social network inventory, and an HIV risk behavior assessment.

RESULTS

Both interview and survey respondents reported consistent use of pharmacies to acquire syringes and nearly universal use of new syringes when injecting. Interview participants reflected that while syringe sharing was previously considered a "common practice," PWID now viewed it as infrequent and unacceptable. However, interview respondents enumerated the contexts in which needle and syringe reuse occurred, including purchasing drugs directly from a dealer and chipping in with other PWID to prepare drugs bought through a stash.

CONCLUSION

Participants described relatively easy access to new needles and syringes through pharmacies and expressed strong social sanctioning against reusing needles or syringes. However, equipment sharing behaviors and norms persisted in certain contexts, creating an opportunity for further harm reduction campaigns that incorporate changing norms in these situations to "close the gap" and further reduce HIV and other infections among PWID.

Educational disparities in joint pain within and across US states: do macro sociopolitical contexts matter?

ABSTRACT

Despite growing recognition of the importance of social, economic, and political contexts for population health and health inequalities, research on pain disparities relies heavily on individual-level data, while neglecting overarching macrolevel factors such as state-level policies and characteristics. Focusing on moderate or severe arthritis-attributable joint pain-a common form of pain that considerably harms individuals' quality of life-we (1) compared joint pain prevalence across US states; (2) estimated educational disparities in joint pain across states; and (3) assessed whether state sociopolitical contexts help explain these 2 forms of cross-state variation. We linked individual-level data on 407,938 adults (ages 25-80 years) from the 2017 Behavioral Risk Factor Surveillance System with state-level data on 6 measures (eg, the Supplemental Nutrition Assistance Program [SNAP], Earned Income Tax Credit, Gini index, and social cohesion index). We conducted multilevel logistic regressions to identify predictors of joint pain and inequalities therein. Prevalence of joint pain varies strikingly across US states: the age-adjusted prevalence ranges from 6.9% in Minnesota to 23.1% in West Virginia. Educational gradients in joint pain exist in all states but vary substantially in magnitude, primarily due to variation in pain prevalence among the least educated. At all education levels, residents of states with greater educational disparities in pain are at a substantially higher risk of pain than peers in states with lower educational disparities. More generous SNAP programs (odds ratio [OR] = 0.925; 95% confidence interval [CI]: 0.963-0.957) and higher social cohesion (OR = 0.819; 95% CI: 0.748-0.896) predict lower overall pain prevalence, and state-level Gini predicts higher pain disparities by education.

The Impact of Health Geography on Public Health Research, Policy, and Practice in Canada

The link between geography and health means that the places we occupy-where we are born, where we live, where we work, and where we play-have a direct impact on our health, including our experiences of health. A subdiscipline of human geography, health geography studies the relationships between our environments and the impact of factors that operate within those environments on human health. Researchers have focused on the social and physical environments, including spatial location, patterns, causes of disease and related outcomes, and health service delivery. The work of health geographers has adopted various theories and philosophies (i.e., positivism, social interactionism, structuralism) and methods to collect and analyze data (i.e., quantitative, qualitative, spatial analysis) to examine our environments and their relationship to health. The field of public health is an organized effort to promote the health of its population and prevent disease, injury, and premature death. Public health agencies and practitioners develop programs, services, and policies to promote healthy environments to support and enable health. This commentary provides an overview of the recent landscape of health geography and makes a case for how health geography is critically important to the field of public health, including examples from the field to highlight these links in practice.

Short-term impact of a neighbourhood-based intervention on mental health and self-rated health in Hamilton, Ontario, Canada

The Hamilton Neighbourhoods Study aimed to measure the short-term impact of a neighbourhood-based intervention known as the City of Hamilton's Neighbourhood Action Strategy on health and neighbourhood outcomes. A quasi-experimental study with 881 intervention participants across six targeted neighbourhoods and 173 control participants was conducted to investigate changes in self-rated health and mental health from baseline to follow-up. There was evidence of small improvements in mental health in two neighbourhoods, but there was no change in self-rated health. Place-based interventions aimed at high poverty neighbourhoods may have only modest impacts on health in the short-term.

COVID-19 brought the water struggles in Ghana into our homes in Canada: Collective emotions and WASH struggles in distant locations during health emergencies

The COVID-19 pandemic has heightened and made visible the embodied consequences of water, sanitation and hygiene (WASH) inequalities and the relationalities of health in place. This paper combines insights from relational geographies and embodied epidemiology to explore psychosocial concerns among Ghanaian migrants in Canada due to their multiple and simultaneous roles in the WASH space in Ghana, particularly during the COVID-19 pandemic. We explored this using narratives from in-depth interviews with 27 participants (16 women and 11 men) residing in Ontario, Canada. The case of Ghana offers insight into how social ties with home communities could provide a safety net during emergencies but could also affect the psychosocial wellbeing of migrants. Results revealed four interrelated psychosocial stressors, including social stressors, financial stressors, stressors related to perceived inequality and stressors related to the fear of infection during WASH access. The paper underscores the urgent need for research to move beyond local health implications of WASH inequalities and begin to prioritize how these social inequalities are embodied at distant locations.

Disparities in violent fatal injury among racial and ethnic minorities, 2009-2019: a portfolio analysis of United States-National Institutes of Health

The excess mortality burden due to violent fatal injuries is an urgent public health issue for adolescents and young adults, especially those from racial and ethnic minority populations. We examined the research portfolio of the United States National Institutes of Health (NIH) related to violent fatal injuries between 2009 and 2019 to focus on adolescents and young adults from NIH-designated populations experiencing health disparities and to identify trends and research gaps. We analyzed funded projects by populations covered, geographic location of the study population, type of research (etiology, intervention, methodology), type of determinants, and publications generated. In 10 years, NIH funded 17 grants that produced 90 publications. Researchers used socioecological frameworks most to study violent crime, except in rural locations. Research gaps include the direct impact of violent crime among those victimized and health care (the least studied determinant) and premature mortality disparities caused by hate crimes.

The effects of contemporary redlining on the mental health of Black residents

Understanding how structural racism, including institutionalized practices such as redlining, influence persistent inequities in health and neighborhood conditions is still emerging in urban health research. Such research often focuses on historical practices, giving the impression that such practices are a thing of the past. However, mortgage lending bias can be readily detected in contemporary datasets and is an active form of structural racism with implications for health and wellbeing. The objective of the current study was to test for associations among multiple measures of mental health and a measure of contemporary redlining. We linked a redlining index constructed using Home Mortgage Disclosure Act data (2007-2013) to 2021 health data for Black/African American participants in the Study of Active Neighborhoods in Detroit (n = 220 with address data). We used multilevel regression models to examine the relationship between redlining and a suite of mental health outcomes (perceived stress, anxiety, depressive symptoms, and satisfaction with life), accounting for covariates including racial composition of the neighborhood. We considered three mediating factors: perceived neighborhood cohesion, aesthetics, and discrimination. Although all participants lived in redlined neighborhoods compared to the complete Detroit Metropolitan area, participants with very low income, low levels of experienced discrimination, and lower perceptions of neighborhood aesthetics resided in highly redlined neighborhoods (score ≥5). We observed that higher resident-reported neighborhood aesthetics were found in neighborhoods with lower redlining scores and were associated with higher levels of satisfaction with life. We found that lower levels of redlining were significantly associated with higher levels of perceived discrimination, which was significantly, positively associated with anxiety, depressive symptoms, and perceived stress scores. Our findings highlight that contemporary redlining practices may influence the aesthetics of the built environment because these neighborhoods experience less investment, with implications for residents' satisfaction with life. However, areas with lower redlining may be areas where Black/African American people experience increased perceived discrimination.

A review of place-related contextual factors in syndemics research

This review investigates the extent to which a place-based approach has been used to conceptualize context, as well as the place-related contextual factors explored in studies that explicitly invoked a syndemic framework. The literature search focused on 29 peer-reviewed empirical syndemic studies. Only 11 studies used a place-based approach to define and measure contextual factors and the spatial context was denoted using administrative boundaries such as census tracts, counties, and countries. A narrow range of place-related contextual factors were explored and most of them were related to social and economic factors that were used to define a place. Methodological gaps like a paucity of multilevel studies and studies using a place-based approach to measure context were identified. Future syndemics research should leverage multidimensional geospatial approaches to decipher the role of place-related contextual factors in syndemic dynamics.
