RESUMO
INTRODUCTION: Healthcare gentrification is the process in which the distribution of healthcare resources within a neighbourhood affects residents' access to healthcare services. To understand the complexity of healthcare access and to consider the socio-structural dimensions affecting equity in access to care, we aim to explore how healthcare gentrification has been described in the scientific literature and to document the reported relations between gentrification and healthcare access. METHODS AND ANALYSIS: We will conduct a scoping review from data published from inception to September 2024 based on the methodology developed by Arksey and O'Malley (2005) and improved by Levac et al (2010). We will search the following databases: MEDLINE (OVID), Embase (embase.com), CINAHL Plus with Full Text (EBSCO), Web of Science and Geobase (Engineering Village). The review will be conducted from February 2024 to September 2024. The search strategy will be elaborated in conjunction with a professional librarian. Screening of titles and abstracts and full-text screening will be done in duplicates. A third reviewer will arbitrate discrepancies during the screening process. We will present our results narratively. ETHICS AND DISSEMINATION: This scoping review does not require ethical approval since it will be collected from publicly available documents. The results of this scoping review will also be presented as a scientific article, scientific conferences, research webinars also in social media, workshops and conferences organised by healthcare organisations or academic institutions or on any appropriate platform.

OBJECTIVES: Alcohol availability is associated with alcohol consumption and related harms, but there is less evidence on associations with heavy episodic drinking (HED), a drinking pattern prevalent among young adults. This study aimed to assess the associations between alcohol availability and HED among young Canadians. METHODS: We used a population-based sample of Canadian urban-dwelling young adult drinkers (18â29 years) from the cross-sectional Canadian Community Health Survey (CCHS; cycles 2015â2019). We linked data from CCHS respondents in British Columbia and Quebec with two measures of alcohol availability for both offsite and onsite outlets: density (AOD) and accessibility (SAI) within dissemination areas (N = 1,067,747). We used logistic regression to estimate the associations between alcohol availability and monthly HED, adjusting for covariates. RESULTS: The associations between availability and HED differed by province, and availability measure. In British Columbia, offsite and onsite accessibility using SAI was inversely associated with HED. For example, living in neighbourhoods with medium alcohol accessibility (as compared to low) was significantly associated with reduced odds of HED (offsite OR = 0.33, 95% CI 0.17â0.64; onsite OR = 0.49, 95% CI 0.27â0.89). In Quebec, offsite availability was positively associated with HED using SAI (although not statistically significant) while no clear trend was seen for onsite availability. CONCLUSION: Results were consistent with previous evidence. Restricting spatial availability of alcohol remains an important public health strategy for decreasing the ease/convenience of access. Understanding why patterns of availability and drinking differ across regions could inform regionally tailored policies.
RéSUMé: OBJECTIFS: La disponibilité des points de vente d'alcool (PVA) dans les quartiers est associée à la consommation d'alcool et aux méfaits qui y sont reliés, mais il y a encore peu de données probantes sur les associations avec la forte consommation épisodique, un mode de consommation d'alcool répandu chez les jeunes adultes. Cette étude visait à évaluer les associations entre la disponibilité des PVA et la forte consommation épisodique d'alcool chez les jeunes adultes canadiens. MéTHODES: Nous avons analysé les données de jeunes adultes (18 à 29 ans) ayant participé à l'Enquête sur la santé dans les collectivités canadiennes (ESCC; cycles 2015â2019) et vivant en milieu urbain en Colombie-Britannique et au Québec. Nous avons couplé ces données à deux mesures de disponibilité des PVA : la densité et l'accessibilité calculées à l'échelle des aires de diffusion (N = 1 067 747). Nous avons estimé les associations entre la disponibilité des PVA, en distinguant les PVA à consommer sur place (p. ex., bars) et pour emporter (p. ex., dépanneurs), et la forte consommation épisodique d'alcool à l'aide de modèles de régression logistique ajustés pour les variables de confusion potentielle. RéSULTATS: Les associations entre la disponibilité des PVA et la forte consommation épisodique différaient selon la province et la mesure de disponibilité choisie. En Colombie-Britannique, l'accessibilité aux PVA à consommer sur place et à emporter était inversement associée à une forte consommation épisodique d'alcool. Par exemple, le fait de vivre dans des quartiers où l'accessibilité à l'alcool était moyenne (comparativement à faible) était significativement associé à une plus faible probabilité de forte consommation épisodique (RC PVA à consommer sur place = 0,49, IC à 95% : 0,27â0,89; RC PVA pour emporter = 0,33, IC à 95% : 0,17â0,64). Au Québec, l'accessibilité aux PVA pour emporter était associée positivement à la forte consommation épisodique (bien que l'association n'était pas statistiquement significative), tandis qu'aucune tendance claire n'a été observée pour la disponibilité des PVA à consommer sur place. CONCLUSION: Nos résultats concordent avec les données probantes antérieures. Restreindre la disponibilité des points de vente d'alcool dans les quartiers demeure une stratégie de santé publique intéressante pour réduire la facilité d'accès à l'alcool. Une exploration plus en profondeur des raisons pour lesquelles les associations entre disponibilité et consommation d'alcool diffèrent entre provinces servirait à énoncer des politiques publiques adaptées aux régions.

INTRODUCTION: Improving sustainable transportation options will help cities tackle growing challenges related to population health, congestion, climate change and inequity. Interventions supporting active transportation face many practical and political hurdles. Implementation science aims to understand how interventions or policies arise, how they can be translated to new contexts or scales and who benefits. Sustainable transportation interventions are complex, and existing implementation science frameworks may not be suitable. To apply and adapt implementation science for healthy cities, we have launched our mixed-methods research programme, CapaCITY/É. We aim to understand how, why and for whom sustainable transportation interventions are successful and when they are not. METHODS AND ANALYSIS: Across nine Canadian municipalities and the State of Victoria (Australia), our research will focus on two types of sustainable transportation interventions: all ages and abilities bicycle networks and motor vehicle speed management interventions. We will (1) document the implementation process and outcomes of both types of sustainable transportation interventions; (2) examine equity, health and mobility impacts of these interventions; (3) advance implementation science by developing a novel sustainable transportation implementation science framework and (4) develop tools for scaling up and scaling out sustainable transportation interventions. Training activities will develop interdisciplinary scholars and practitioners able to work at the nexus of academia and sustainable cities. ETHICS AND DISSEMINATION: This study received approval from the Simon Fraser University Office of Ethics Research (H22-03469). A Knowledge Mobilization Hub will coordinate dissemination of findings via a website; presentations to academic, community organisations and practitioner audiences; and through peer-reviewed articles.

Introduction: Exiting sex work is a complex process which can be facilitated by integrated action on health and its social determinants such as housing and employment. Few programs offer such coordinated support, and even fewer have been evaluated. We assessed if and how Exit Doors Here, a program anchored in the Critical Time Intervention (CTI) model, facilitated women's progress towards their goals, and exit from sex work. Description: We performed a contribution analysis by combining pre-post questionnaire and administrative data from 55 women enrolled in the program (2018-2021), yearly interviews with program staff and peer mentors, and literature reviews to assess program outcomes and mechanisms as described in the theory of change. Discussion: We found evidence that the program contributed to participants progressing on their pre-employment, housing, income, and sex work exiting goals. We identified four "key ingredients" facilitating success: trust building, collaborative goal setting, connecting with community supports and weekly drop-in sessions. Conclusion: This rigorous theory-based evaluation provides much needed evidence on the process and effectiveness of an integrated sex work exiting program. Findings regarding key program ingredients can inform other interventions serving similarly marginalized populations.
RESUMO
INTRODUCTION: Young adult drinking is a public health priority, but knowledge of socioeconomic status (SES) indicators and alcohol use among emerging adults (EAs; aged 18-29 years) is primarily informed by college samples, populations in their late teens and early twenties and non-Canadian data. We compared the association of three different SES indicators with monthly heavy episodic drinking (HED), less-than-monthly HED, no HED, and no drinking among Canadian EAs. METHODS: We pooled the 2015 to 2019 waves of the Canadian Community Health Survey to include participants aged 18 to 29 years (n = 29 598). Using multinomial regression, we calculated weighted estimates of alcohol use by education, household income and area-level disadvantage, adjusting for adult roles and sociodemographic characteristics. RESULTS: Approximately 30% of EAs engaged in monthly HED, whereas 16% did not drink at all in the past year. Compared to those in the lowest household incomes, being in the top income quintile was significantly associated with increased relative odds of monthly HED (e.g. in combined SES model, RRR = 1.21, 95% CI: 1.04-1.39). Higher levels of education, being in higher income quintiles and living in less disadvantaged areas were significantly associated with reduced relative odds of no HED and not drinking. Adjusting for adult roles did not substantially change the associations between SES and alcohol use. CONCLUSION: Higher SES was associated with HED among EAs, although the magnitude of association was small. Universal prevention measures addressing the affordability, availability and marketing of alcohol could be complemented by interventions targeting EA populations at higher risk of HED.

Poor health and well-being are prevalent among young people. Neighborhoods may play a role in promoting good health. Little is known on if and how neighborhood characteristics affect health, and social inequalities therein, among young people. In this scoping review, we asked: (1) what features of the neighborhood physical and social environments have been studied in association with the physical and mental health and well-being of young people 15 to 30 years old; and (2) to what extent have social differentials in these associations been studied, and how? We identified peer-reviewed articles (2000 to 2023) through database and snowball searches. We summarized study characteristics, exposure(s), outcome(s) and main findings, with an eye on social inequalities in health. Out of the 69 articles reviewed, most were quantitative, cross-sectional, conducted among 18-year-olds and younger, and focused on the residential neighborhood. Neighborhood social capital and mental health were the most common exposure and outcome studied, respectively. Almost half of the studies examined social inequalities in health, mostly across sex/gender, socioeconomic status, and ethnicity. Evidence gaps remain, which include exploring settings other than residential neighborhoods, studying the older age stratum of young adulthood, and assessing a broader range of social inequalities. Addressing these gaps can support research and action on designing healthy and equitable neighborhoods for young people.

An emerging approach to facilitating exiting sex work is through applying the Critical Time Intervention [CTI] model. CTI represents a time-limited approach that supports marginalized individuals during periods of transition. We performed a fidelity assessment as part of a process evaluation of Exit Doors Here [EDH], a program supporting women who wish to exit sex work. We reflect on the appropriateness of the CTI model for supporting these women, and highlight contextual and population specificities which might need to be considered for effective scaling up of similar programs. First, we applied an existing fidelity assessment tool to the EDH program. Program staff highlighted areas for adaptation. We then adapted the tool based on this feedback and assessed program fidelity by analyzing data from eight participants' CTI charts. Fidelity ratings were computed and interpreted according to established guidelines. Consultations with program staff resulted in adaptations to seven of the 12 fidelity assessment tool items. The majority of adaptations surrounded the time-limited nature of CTI and unique needs of the program participants such as their experiences with violence and substance use. The fidelity assessment of the adapted tool demonstrated that even after adaptations were made, certain items were still not appropriate for this study population. Difficulties in implementing selected program components with high fidelity can be attributed to contextual and population specificities of the study population. This study reiterates the importance of considering such factors when developing and implementing programs aimed at improving the health and livelihoods of marginalized women such as those who engage in sex work.
Limited research exists that speaks to the appropriateness of the Critical Time Intervention [CTI] model for women who attempt to exit sex work. We found that many components of the CTI model [e.g., time limited nature] were not appropriate for providing care to women who engage with sex work due to their complex and intersecting needs/realities. Considering population specificities is key to providing effective health and social care to these groups. These findings contribute to existing gaps in the implementation science literature and program development which aims to assist women exit sex work and other similarly marginalized groups.

Evidence on how the COVID-19 pandemic has affected women's reproductive health remains scarce, particularly for low- and middle-income countries. Deleterious indirect effects seem likely, particularly on access to contraception and risk of unwanted pregnancies, but rigorous evaluations using quasi-experimental designs are lacking. Taking a diachronic perspective, we aimed to investigate the effects of the pandemic on four indicators of women's reproductive health: history of recent adverse events during pregnancy (past), use of contraception and unwanted pregnancies (present), and childbearing intentions (future). This study was conducted in four rural health districts of Burkina Faso: Banfora, Leo, Sindou and Tenado. Two rounds of household surveys (before and during the pandemic) were conducted in a panel of 696 households using standardized questionnaires. The households were selected using a stratified two-stage random sampling method. All women aged 15-49 years living in the household were eligible for the study. The same households were visited twice, in February 2020 and February 2021. The effects were estimated by fitting hierarchical regression models with fixed effects or random intercepts at the individual level. A total of 814 and 597 women reported being sexually active before and during the COVID-19 pandemic, respectively. The odds of not wanting (any more) children were two times higher during the pandemic than before (2.0, 95% CI [1.32-3.04]). Among those with childbearing intention, the average desired delay until the next pregnancy increased from 28.7 to 32.8 months. When comparing 2021 versus 2020, there was an increase in the adjusted odds ratio of contraception use (1.23, 95% CI [1.08-1.40]), unwanted pregnancies (2.07, 95% CI [1.01-4.25]), and self-reported history of miscarriages, abortions, or stillbirths in the previous 12 months (2.4, 95% CI [1.04-5.43]). Our findings in rural Burkina Faso do not support the predicted detrimental effects of COVID-19 on the use of family planning services in LMICs, but confirm that it negatively affects pregnancy intentions. Use of contraception increased significantly among women in the panel, but arguably not enough to avoid an increase in unwanted pregnancies.
RESUMO
The COVID-19 pandemic and associated public health preventive measures such as lockdown and home confinement have posed unique challenges to female sex workers (FSW) globally, including in Canada where the sex trade is not formally recognized. In this commentary, we discuss the unintended consequences the pandemic has had on various social determinants of health among FSW. We draw on a review of scholarly and grey literature, complemented by our experience with the Exit Doors Here program, a sex work exiting program implemented in Toronto, Canada. Due to COVID-19, many FSW suddenly lost their main source of income, work conditions became riskier, and sheltering-in-place presented challenges for women with no safe housing. The slowdown of social and health care services also meant FSW were not receiving the required attention. We make recommendations for intersectoral mitigation strategies to limit the short- and long-term impacts of COVID-19 on FSW health and livelihoods. Recommendations focus on addressing women's marginalizing circumstances and speak to a gender transformative approach to the COVID-19 recovery. Our recommendations are relevant to FSW and other marginalized groups, in the current context and in the context of future health, social, and economic crises.

In-situ methodologies, including go-along and photo-elicited interviews, are ideal for harnessing people's lived experiences of place and their meanings for health and health equity. Their immersive nature means that the COVID-19 pandemic has impacted their use. Physical distancing measures combined to anxiety over the sharing of physical space have created ethical and practical challenges to the conduct of in-person in-situ methodologies. However, in-situ methodologies are precisely needed to gain deeper understandings of people's changing relationships to place post-COVID-19. In this commentary we discuss emerging challenges, highlight questions researchers should ask before engaging in these methods in the future, and explore adaptations and alternatives to traditional in-person in-situ methodologies.

During the first wave of the COVID-19 pandemic, global measures preventing the spread of the new coronavirus required most of the population to lockdown at home. This sudden halt to collective life meant that non-essential services were closed and many health promoting activities (i.e. physical activity, school) were stopped in their tracks. To curb the negative health impacts of lockdown measures, activities adapting to this new reality were urgently developed. One form of activity promoted indoor physical activity to prevent the adverse physical and psychological effects of the lockdown. Another form of activity included the rapid development of online learning tools to keep children and youth engaged academically while not attending school. While these health promoting efforts were meant to benefit the general population, we argue that these interventions may have unintended consequences and inadvertently increase health inequalities affecting marginalized youth in particular, as they may not reap the same benefits, both social and physical, from the interventions promoting at-home physical activities or distance learning measures. We elaborate on several interventions and their possible unintended consequences for marginalized youth and suggest several strategies that may mitigate their impact.

BACKGROUND: For women who want to, exiting sex work can be challenging. Numerous programs strive to help women wanting to exit sex work and secure alternative sources of income by providing targeted support at key moments during the transition, yet few of those initiatives are rigorously evaluated. In 2017 "Exit Doors Here", a 9-month sex work exiting program based on the critical time intervention (CTI) approach, was developed to provide wrap-around support services (e.g., health, addiction, housing, education, and employment supports) to women wishing to transition towards exiting sex work. METHODS: We present the design of an evaluation study of Exit Doors Here which combines quantitative and qualitative methods to assess participant recruitment and retention into the program, program fidelity, and relationships with service providers (process evaluation), as well as progress made by participants in terms of strengthening their social support networks and moving closer to achieving their housing, pre-employment (i.e., educational, training and volunteering), and income-related goals, as well as their involvement in sex work (outcome evaluation). Each year for 4 years, between 25 and 30 Exit Doors Here clients will be invited to complete an interviewer-administered questionnaire at the beginning and after completing the program, and to share data from their CTI charts and related documentation. Once a year, program staff and peer workers will be interviewed, and service providers will be surveyed. DISCUSSION: Conducting a formative (process) evaluation will allow us to inform program implementation and improve program delivery early on for maximum benefit. The summative (outcome) evaluation will provide much needed evidence on the effectiveness of CTI in supporting a traditionally underserved population to achieve the housing, pre-employment and income-related goals they value, and their progress towards reducing their involvement in, and eventually exiting, sex work.

Neighbourhood resources are often considered to be spatially accessible to people when they are located close to their place of residence, a perspective which overlooks individuals' unique lived experience of their neighbourhood and how they define it. Drawing on the relational approach to place and on Sen's capability approach, we explore spatial accessibility to health-related resources, and the social gradient therein, in light of people's place experiences. Using data from 1101 young adults from Montreal (Canada) who participated in the Interdisciplinary Study of Inequalities in Smoking (ISIS), we compare the social gradients in the presence of health-related resources located (i) within uniform areas (defined as circular buffers and road-network buffers) around participants' place of residence; and (ii) within participants' self-defined neighbourhoods. Social inequalities in accessibility to a diversity of health-related resources (grocery stores, fruit and vegetable stores, eating and drinking places, recreational sports centres, civic, social, and fraternal organizations, bike paths, parks, social services, libraries, dental offices, physician offices) were more pronounced in self-defined neighbourhoods than in uniform buffer areas. Neglecting the variability in people's place experiences may distort the assessment of social inequalities in accessibility, and ultimately, of neighbourhood effects on health inequalities.

INTRODUCTION: The presence of tobacco retailers in residential neighborhoods has been inversely associated with residents' likelihood of quitting smoking. Few studies have yet explored whether this association holds when accounting for tobacco retailers found in the multiple environments where people conduct their daily activities, that is, their activity space. METHODS: We analyzed cross-sectional data from 921 young adults (18- to 25-years old) participating in the Interdisciplinary Study of Inequalities in Smoking (Montreal, Canada). Respondents self-reported sociodemographic, smoking, and activity location data. Log-binomial regression was used to estimate prevalence ratios (PRs) for the association between smoking cessation and (1) the number of tobacco retailers (counts), and (2) the distance to the closest retailer (proximity) in participants' residential neighborhood and activity space. RESULTS: Smoking cessation was positively associated with low and intermediate tertile levels of tobacco retailer counts in both the residential neighborhood and activity space, and with the furthest distance level in the activity space [PR (95% CI) = 1.21 (1.02 to 1.43)]. CONCLUSIONS: Individuals encounter resources in the course of their regular daily activities that may hamper smoking cessation. This study highlights the relevance of considering the tobacco retail environment of both individuals' residential neighborhood and activity space to understand its association with smoking cessation. IMPLICATIONS: This article contributes to the literature on the association between the tobacco retail environment and smoking cessation in young adults by moving beyond the residential neighborhood to also assess individuals' access to tobacco retailers in the multiple areas where they regularly spend time, that is, their activity space. Findings suggest that lower numbers of tobacco retailers in both the residential neighborhood and activity space, and further distance to tobacco retailers in the activity space are associated with increased smoking cessation.

The neighborhood food environment may contribute to ethnic inequalities in diet. Using data from 1389 participants in the Olympic Regeneration in East London (UK) study we assessed whether ethnic inequalities in neighborhood availability of fast-food restaurants mediated and/or modified ethnic inequalities in fast-food intake in 13-15â¯year-old adolescents. We compared the proportion of high fast-food consumers across "White UK", "Black", and "South Asian" ethnic categories. We used Poisson regression with robust standard errors to assess direct and indirect effects (mediation analysis) and risk ratios of high fast-food intake by ethnic category and fast-food restaurant availability level (effect measure modification analysis). There were ethnic inequalities in high fast-food intake, with risk ratios in adolescents of Black and South Asian background of 1.53 (95% CI: 1.25, 1.87) and 1.71 (95% CI: 1.41, 2.07) respectively compared to White UK participants. We found no evidence of a mediating effect by fast-food restaurant availability, but found some evidence of effect measure modification: ethnic inequalities in fast-food intake were largest in neighborhoods lacking fast-food restaurants, and narrowed as availability increased. Future research should explore why ethnic minorities are more likely to be high fast-food consumers than the majority ethnic group, especially when fast-food restaurant availability is lowest.
RESUMO
The objective of this study was to explore relationships between the neighborhood food environment and obesity in urban women living in São Leopoldo, Rio Grande do Sul State, Brazil. A cross-sectional survey was carried out. This study was conducted with 1,096 women. Structured interviews were conducted using a standard pre-tested questionnaire. Obesity was defined as body mass index (BMI) ≥ 30kg/m2. Circular buffers of 400m in radius were created based on the centroid of the women's houses who participated, in the 45 census tracts inhabited by them. Neighborhood food establishments were identified through systematic survey of all streets in the study areas and geographical coordinates of shops were collected. Establishments were evaluated using the NEMS tool. The prevalence of obesity was 33% among the women participants. After adjusting for individual variables, supermarkets and healthy food establishments were positively associated with obesity, PR = 1.05 (95%CI: 1.01-1.10), PR = 1.02 (95%CI: 1.00-1.04), respectively, while mean buffer income was negatively associated, PR = 0.64 (95%CI: 0.49-0.83). Neighborhood food environment factors were associated with obesity even after controlled for individual variables, as socioeconomic variables, behavioral and food purchase.

Devices equipped with sensors to track mobility, such as through Global Position Systems (GPS) and accelerometery, are increasingly being used for research. Following Canadian, US, and International guidelines there is a need to give special consideration when conducting research with vulnerable populations. This paper examines specific ethical concerns for conducting research with mobile sensing devices for use by vulnerable populations, considering aspects of both research design and research process. Drawing on insights from feminist design and aligned fields, such as participatory design and action research, we contend that any research design and process for working with vulnerable populations must be developed in collaboration with the particular groups and communities who are part of the research. As part of this process of collaborative research, we discuss risks in terms of the lack of control over data associated with choosing commercial devices, as well as practicality and obtrusiveness of devices for the wearer. We also discuss the significance of informed consent and refusal and issues relating to security and safety during research. As part of the collaborative research design and process, we argue that participants should be given as much control over their data as possible. Based on this discussion, we provide recommendations for researchers to consider, which are broadly relevant for research using mobile sensing devices but particularly significant in relation to vulnerable populations.

O estudo teve como objetivo explorar as relações entre o ambiente alimentar da vizinhança e obesidade em mulheres na área urbana de São Leopoldo, Rio Grande do Sul, Brasil, através de um inquérito transversal. O estudo teve uma amostra de 1.096 mulheres. Foram realizadas entrevistas estruturadas com um questionário padronizado e previamente testado. A obesidade foi definida como índice de massa corporal (IMC) ≥ 30kg/m2. Foram criadas zonas-tampão com raio de 400m em torno do centroide das residências das participantes nos 45 setores censitários. Os estabelecimentos varejistas com venda de alimentos na vizinhança foram identificados através de uma pesquisa sistemática das áreas do estudo, e foram coletadas as coordenadas geográficas dessas lojas. Os estabelecimentos foram avaliados com a ferramenta NEMS. A prevalência de obesidade foi 33% entre as participantes. Depois de ajustar para as variáveis individuais, os supermercados e os estabelecimentos com alimentos saudáveis mostraram uma associação positiva com a obesidade, RP = 1,05 (IC95%: 1,01-1,10), RP = 1,02 (IC95%: 1,00-1,04), respectivamente, enquanto que a renda média da zona-tampão mostrou associação negativa, RP = 0,64 (IC95%: 0,49-0,83). Os fatores de ambiente alimentar da vizinhança estiveram associados à obesidade, mesmo depois de controlar para as variáveis individuais, socioeconômicas, comportamentais e de compra de alimentos.
El objetivo de este estudio fue investigar las relaciones entre el entorno alimentario del vecindario y la obesidad en mujeres que viven en áreas urbanas de São Leopoldo, Rio Grande do Sul, Brasil. Se llevó a cabo un estudio transversal. Este estudio se realizó con 1.096 mujeres. Se realizaron entrevistas estructuradas, usando un cuestionario estándar probado previamente. La obesidad se definió como un índice de masa corporal (IMC) ≥ 30kg/m2. Se crearon amortiguadores circulares en un radio de 400m, basados en el centroide de las casas de las mujeres que participaron, en los 45 distritos censales donde residían. Los establecimientos de comida del vecindario fueron identificados mediante un estudio sistemático de todas las calles en las áreas de estudio y también se recabaron las coordenadas geográficas de las tiendas. Los establecimientos fueron evaluados usando el instrumento NEMS. La prevalencia de obesidad fue de un 33% entre las mujeres participantes. Tras el ajuste de las variables individuales, los supermercados y los establecimientos de comida sana estuvieron positivamente asociados con la obesidad, RP = 1,05 (IC95%: 1,01-1,10), RP = 1,02 (IC95%: 1,00-1,04), respectivamente, mientras que un promedio de renta media estuvo negativamente asociado, RP = 0,64 (IC95%: 0,49-0,83). Los factores del vecindario en el entorno alimentario estuvieron asociados con la obesidad incluso después de ser controlados por variables individuales como: socioeconómicas, comportamentales y de compra de comida.

OBJECTIVE: To examine associations between availability of fast-food restaurants and convenience stores in the home and school neighbourhoods, considered separately and together, and adolescents' fast-food and sugar-sweetened beverage (SSB) intakes. DESIGN: Cross-sectional observational study. SETTING: East London, UK. SUBJECTS: Adolescents (n 3089; aged 13-15 years) from the Olympic Regeneration in East London (ORiEL) Study self-reported their weekly frequency of fast-food and SSB consumption. We used food business addresses collected from local authority registers to derive absolute (counts) and relative (proportions) exposure measures to fast-food restaurants and convenience stores within 800 m from home, school, and home and school combined. Associations between absolute and relative measures of the food environment and fast-food and SSB intakes were assessed using Poisson regression models with robust standard errors. RESULTS: Absolute exposure to fast-food restaurants or convenience stores in the home, school, or combined home and school neighbourhoods was not associated with any of the outcomes. High SSB intake was associated with relative exposure to convenience stores in the residential neighbourhood (risk ratio=1·45; 95 % CI 1·08, 1·96) and in the home and school neighbourhoods combined (risk ratio=1·69; 95 % CI 1·11, 2·57). CONCLUSIONS: We found no evidence of an association between absolute exposure to fast-food restaurants and convenience stores around home and school and adolescents' fast-food and SSB intakes. Relative exposure, which measures the local diversity of the neighbourhood food environment, was positively associated with SSB intake. Relative measures of the food environment may better capture the environmental risks for poor diet than absolute measures.

BACKGROUND: Accounting for daily mobility allows assessment of multiple exposure to environments. This study compares spatial data obtained (i) from an interactive map-based questionnaire on regular activity locations (VERITAS) and (ii) from GPS tracking. METHODS: 234 participants of the RECORD GPS Study completed the VERITAS questionnaire and wore a GPS tracker for 7 days. Analyses illustrate the spatial match between both datasets. RESULTS: For half of the sample, 85.5% of GPS data fell within 500 m of a VERITAS location. The median minimum distance between a VERITAS location and a GPS coordinate ranged from 0.4â¯m for home to slightly over 100â¯m for a recreational destination. CONCLUSIONS: There is a spatial correspondence between destinations collected through VERITAS and 7-day GPS tracking. Both collection methods offer complementary ways to assess daily mobilities, useful to study environmental determinants of health and health inequities.
