Leveraging Citizen Science and Information Technology for Population Physical Activity Promotion

How is health considered in urban transport planning? A review of the literature

OBJECTIVES

Urban transport is an important determinant of population health. Ensuring health is well considered in urban transport planning is important to create healthy cities, healthy populations and sustainable societies. This review aimed to describe how health is considered in urban transport planning.

STUDY DESIGN

A narrative literature review was conducted.

METHODS

Eligible literature included research articles, review articles, perspective articles, policy reports and technical reports published in English since 2013. PubMed, the Transport Research Integrated Database and grey literature sources were searched.

RESULTS

Seventy articles were included, predominantly from high-income countries. Findings indicated that while urban transport is well recognised as a determinant of health, health considerations are often underprioritized in urban transport planning. Key issues identified included systemic power imbalances favouring car-orientated planning, insufficient legislative frameworks to promote health, the non-holistic assessment of health impacts in established environmental assessment processes, transport appraisal methodologies which undervalued health and differences between the health and planning professions in their preferred sources of evidence with associated challenges in knowledge translation. A consistent theme in the literature was that a strategic approach needed to be taken to improve how health is considered in urban transport planning and central to this was building relationships to enable collaborative and partnership working.

CONCLUSION

Health was poorly considered in urban transport planning. Contributing issues related to power, legislation, impact assessment and knowledge translation. A strategic approach is important to address these issues.

Partnering with Communities to Understand Social Determinants of Health (SDoH) Impacts on Access to Shared Micromobility

This study explored the facilitators and barriers of community bike share use in a mid-sized city with high incidence of poverty and racial diversity using a community-based participatory action research (CBPAR) photovoice framework with the Stanford Our Voice (OV) Discovery Tool digital application. Community members participated in one of three community citizen science walks with follow up focus groups facilitated by osteopathic medical student researcher to address "What makes it easy or hard to ride a bike using the bike share?" Twenty-seven diverse community members partnered with four osteopathic medical students exploring vulnerable individuals' lived experiences, beliefs/understanding of the Social Determinants of Health (SDoH) and access to the bike share program. A total of 322 photos and narrative comments from citizen science walk audits developed deductive themes and follow up focus groups informed inductive themes. Themes addressed challenges to access, maintenance, safety in bike transit, comfort, and environment that create barriers to use and increase inequities for lower income and historically underrepresented communities. The use of OV provided photograph, narrative, and geocoded photo location. This novel approach served as an effective tool for community action with city decision makers. The narrative research identified the impact of the barriers, and the photographs and geocoding provided clear descriptions for locations to prioritize change by adding street signs for access and safety, fixing road safety issues or bike maintenance concerns. It actively engaged the community with the city to drive discussions and plans for change in repair systems and infrastructure that also addressed equity and acknowledged the SDoH supporting residents in lower income or historically underrepresented communities. Citizen science engaged community voices, supporting change in city policies and transportation initiatives to support the sustainability of the bike share program.

Using citizen science to explore barriers and facilitators for healthy and sustainable lifestyles in office environments

The socio ecological model states that individual behaviors at work are shaped by the interactions between individual employees and their work environments. This study used citizen science to gain insights into which elements of the built, social, and organizational environment in an office and surrounding neighborhoods in two Swedish cities were perceived as barriers to or facilitators of healthy and sustainable behaviors at work. Participants in the eight-week Sustainable Office Intervention pilot study (SOFIA) (n = 33) were cluster-randomized into an experimental arm (sustainable lifestyle) or a control intervention arm (healthy lifestyle). They used the Our Voice Healthy Neighborhood Discovery Tool mobile app to document contextual elements at their workplaces. In total, 114 photos and text-based narratives were recorded, and four themes emerged: built environment, building design, office ergonomics, and food and beverages. Eighteen percent of the photos were linked to pro-environmental behaviors, all exclusively captured by the experimental arm. Twelve barriers and solutions for improving the workplace environment were identified during discussions with participants in both arms. The findings provide insights for designing or renovating office spaces and urban planning to promote healthier and more sustainable lifestyles for office workers.

Fostering collective action for adolescent well-being: citizen science in a Colombian semi-rural area

We present findings from the Our Voice in Barú project, examining adolescent engagement in citizen science to address environmental and social factors affecting well-being in a semi-rural Afro-descendant community in Latin America. The project aimed to identify barriers and enablers of well-being, informing adolescent-led actions for sustainable environmental changes relevant to adolescent health. Utilizing the Our Voice citizen science method, which involved technology-enabled walks, participatory cartography workshops and community meetings, we engaged adolescents and other community members. Complex systems framework was employed to analyze results and assess the promotion of collective action and local change. Local enablers of well-being included availability of quality sports and recreational venues as safe spaces, educational settings and cultural aspects, fostering safety, community pride, and personal growth. Conversely, barriers included environmental contamination, deteriorated sports venues and drug addiction, indicating the community's limited access to services and exposure to harmful substances. Adolescent citizen scientists, in partnership with the research team and relevant community decision-makers, successfully achieved changes aimed at identified barriers, including infrastructural enhancements like the repair of pumps to remove stagnant water, improvements in the quality and safety of recreational venues, and the implementation of community-led initiatives to address substance abuse and promote healthier behaviors. The Our Voice in Barú project empowered adolescents to advocate for change and promoted collective action to tackle barriers identified as significant to their well-being.

Stakeholder perspectives on the barriers and facilitators of engagement in healthy lifestyle behaviours in underrepresented adolescents: a focus group study from the European SEEDS project

BACKGROUND

Obesity in adolescence has increased in the last decades. Adolescents fail to meet the recommended guidelines for physical activity (PA) and healthy diet. Adolescents with a low socioeconomic status (SES) particularly seem to have fewer healthy lifestyle behaviours. The European Science Engagement to Empower aDolescentS (SEEDS) project used an extreme citizen science approach to develop and implement healthy lifestyle behaviour interventions in high schools. As part of this project, key stakeholders were invited to reflect on the intentions of adolescents to engage in healthy lifestyle behaviours. The aim of this study was to gain stakeholder insights into the barriers and facilitators to healthy lifestyle behaviours of adolescents from low SES areas and on the possible role of these stakeholders in facilitating healthy lifestyle behaviours.

METHODS

Six semi-structured focus groups were conducted in four European countries with 28 stakeholders from different settings (schools, community, and government), like teachers, policy advisors and youth workers. The theoretical framework of focus groups was based on the Theory of Planned Behaviour. The main questions of the focus groups were centred on PA and healthy diet. The focus groups were qualitatively analysed in NVivo using thematic analysis to identify topics and themes.

RESULTS

According to stakeholders, adolescents have sufficient understanding of the importance of PA and a healthy diet, but nevertheless engage in unhealthy behaviour. Parents were mentioned as important facilitators for engaging adolescents in healthy lifestyle behaviours. Stakeholders listed lack of knowledge, time, and financial resources as barriers for adolescents from low SES families to engage in healthy lifestyle behaviours. The school environment was listed as an important facilitator of adolescents' healthy lifestyle changes, but stakeholders acknowledged that current school days, curriculum and buildings are not designed to promote healthy lifestyle behaviours. External support and collaboration with community and governmental stakeholders was seen as potentially beneficial to improve healthy lifestyle behaviours.

CONCLUSIONS

This study shows the variety of barriers adolescents from low SES areas face, and the need for a broader collaboration between key stakeholders to facilitate healthy lifestyle behaviours. Schools are regarded specifically as important facilitators. Currently, the school environment entails various barriers. However, when addressing those, schools can increase opportunities for healthy lifestyle behaviours of adolescents from low SES areas.

TRIAL REGISTRATION

This study is registered in ClinicalTrials.gov on 12/08/2021: NCT05002049.

"The Real Impacts That AAAs are Making:" Developing Measures of Area Agency on Aging Success

The more than 600 Area Agencies on Aging (AAAs) throughout the U.S. are as diverse as the communities they serve, making it challenging to establish indicators of success that are not simply compliance-focused. This study builds agreement among AAAs to identify impactful, feasible, and measurable indicators of success. A mixed methods study was conducted with two surveys of AAA experts to identify indicators of success; assessments of those indicators' impact, feasibility, and measurability; and virtual focus groups to interpret findings. Most indicators that had the potential for high impact received low feasibility and measurability scores. AAAs want more technical assistance, funding, and staffing resources from their states and the Administration on Aging to make data collection and analysis less burdensome and more outcome-oriented. State Units on Aging and the Administration on Aging can use the study findings to improve assessments of AAAs without placing undue burdens on staff attempting to demonstrate their impact. This study can help to identify future priorities regarding AAA assessments and innovations.

Using photovoice to generate policy recommendations to improve the alcohol urban environment: A participatory action research project

The place where we live, work and play may influence our alcohol drinking behaviours. This study aimed to present local policy recommendations on urban determinants for alcohol consumption prevention in a low-income and a high-income area of Madrid (Spain) using a participatory action research method, with photovoice and nominal group techniques. Participants (n = 26) engaged in a photovoice project initiated a process of critical reflection by discussing and analysing their alcohol environment based on photographs they took themselves. At the end of six week group discussion sessions, participants identified 33 themes related to their alcohol environment. They later met to translate the final categories into urban policy recommendations using a logical framework approach. Then, with a nominal group, they prioritized these recommendations based on time, impact, feasibility, and cost. Finally, participants produced a total of 61 policy recommendations for the improvement of the alcohol environment, highlighting the need for researcher-community collaborations when designing public health interventions.

Citizen science approaches to crowdsourcing food environment data: A scoping review of the literature

Globally, the adoption and implementation of policies to improve the healthiness of food environments and prevent population weight gain have been inadequate. This is partly because of the complexity associated with monitoring dynamic food environments. Crowdsourcing is a citizen science approach that can increase the extent and nature of food environment data collection by engaging citizens as sensors or volunteered computing experts. There has been no literature synthesis to guide the application of crowdsourcing to food environment monitoring. We systematically conducted a scoping review to address this gap. Forty-two articles met our eligibility criteria. Photovoice techniques were the most employed methodological approaches (n = 25 studies), commonly used to understand overall access to healthy food. A small number of studies made purpose-built apps to collect price or nutritional composition data and were scaled to receive large amounts of data points. Twenty-nine studies crowdsourced food environment data by engaging priority populations (e.g., households receiving low incomes). There is growing potential to develop scalable crowdsourcing platforms to understand food environments through the eyes of everyday people. Such crowdsourced data may improve public and policy engagement with equitable food policy actions.

Exploring views and experiences of the general public's adoption of digital technologies for healthy lifestyle in Singapore: a qualitative study

Objective

Little is known about the general adult population's adoption of digital technology to support healthy lifestyle, especially when they are expected to take greater personal responsibility for managing their health and well-being today. The current qualitative study intended to gain an in-depth understanding of determinants of digital technology adoption for healthy lifestyle among community-dwelling adults in Singapore.

Design

A qualitative study design, with thematic framework analysis was applied to develop themes from the data.

Setting

Semi-structured individual interviews were conducted with participants either face-to-face or online through a videoconferencing platform.

Participants

14 women and 16 men from the general population who were between the ages of 22 and 71 years.

Results

Three major themes were developed: (1) digitally disempowered (2) safety and perceived risks and harm; (3) cultural values and drives. Adoption of technology among the general population is needs-driven, and contingent on individual, technological and other cross-cultural contextual factors.

Conclusion

Our findings highlight there is no one solution which fits all individuals, emphasizing the challenges of catering to diverse groups to reduce barriers to adoption of digital technologies for healthy lifestyle. Digital guidance and training, as well as social influences, can motivate technological adoption in the population. However, technical problems as well as data security and privacy concerns should first be adequately addressed. This study provides rich cross-cultural insights and informs policy-making due to its alignment with government public health initiatives to promote healthy lifestyle.

Best practice guidelines for citizen science in mental health research: systematic review and evidence synthesis

Partnering with people most affected by mental health problems can transform mental health outcomes. Citizen science as a research approach enables partnering with the public at a substantial scale, but there is scarce guidance on its use in mental health research. To develop best practise guidelines for conducting and reporting research, we conducted a systematic review of studies reporting mental health citizen science research. Documents were identified from electronic databases (n = 10), grey literature, conference proceedings, hand searching of specific journals and citation tracking. Document content was organised in NVIVO using the ten European Citizen Science Association (ECSA) citizen science principles. Best practise guidelines were developed by (a) identifying approaches specific to mental health research or where citizen science and mental health practises differ, (b) identifying relevant published reporting guidelines and methodologies already used in mental health research, and (c) identifying specific elements to include in reporting studies. A total of 14,063 documents were screened. Nine studies were included, from Australia, Belgium, Canada, Denmark, Netherlands, Spain, the UK, and the United States. Citizen scientists with lived experience of mental health problems were involved in data collection, analysis, project design, leadership, and dissemination of results. Most studies reported against some ECSA principles but reporting against these principles was often unclear and unstated. Best practise guidelines were developed, which identified mental health-specific issues relevant to citizen science, and reporting recommendations. These included citizen science as a mechanism for empowering people affected by mental health problems, attending to safeguarding issues such as health-related advice being shared between contributors, the use of existing health research reporting guidelines, evaluating the benefits for contributors and impact on researchers, explicit reporting of participation at each research stage, naming the citizen science platform and data repository, and clear reporting of consent processes, data ownership, and data sharing arrangements. We conclude that citizen science is feasible in mental health and can be complementary to other participatory approaches. It can contribute to active involvement, engagement, and knowledge production with the public. The proposed guidelines will support the quality of citizen science reporting.

Engaging Nigerian Older Persons in Neighborhood Environment Assessment for Physical Activity Participation: A Citizen Science Project

Background and Objectives

Global organizations are advocating that older persons' voices should guide communities in age-friendly design. An important aspect of age friendliness to enable daily function and health is ensuring that physical activity can occur, regardless of age, within local neighborhoods.

Research Design and Methods

This study used a specific citizen science approach, Our Voice, to engage a sample (N = 13) of older adults (60 or older) in Festac Town, Nigeria. The citizen scientists' roles were to assess and identify how different aspects of the neighborhood environment act as supports or barriers to their physical activity participation. They were individually enabled using a tablet-based mobile application called the Stanford Healthy Neighborhood Discovery Tool to record a total of 156 geocoded photos and 151 commentaries of neighborhood environmental features that facilitate or hinder physical activity in and around their neighborhoods. In a guided process, the following occurred: collaborative discussions of findings with other citizen scientists to determine common targets, setting of priority targets for change, and brainstorming strategies and solutions.

Results

Facilitators of physical activity included: pedestrian and traffic facilities (e.g., traffic lights, walkways); green areas and parks; multigenerational community features (e.g., programs/facilities); opportunities for social connection (e.g., neighborhood associations, churches); safety of destinations and services; and public toilets. Barriers to physical activity included: hazardous walkways/traffic; noise pollution; refuse, selling of public parks; crime (e.g., kidnapping, criminal hideouts); no safe drinking water; and ageism. The priorities for changes were social connectivity; improved pedestrian and traffic facilities; and green and beautiful environments.

Discussion and Implications

In this study, both physical and social aspects of the environment were deemed important for older Nigerians to enable physical activity in their local community. This approach has a promise for age-friendly initiatives seeking local changes by meaningfully engaging older adults.

How Can Sport-Based Interventions Improve Health among Women and Girls? A Scoping Review

Sport has been identified by the World Health Organization as an underutilized yet important contributor to global physical activity, by UNESCO as a fundamental right, and by the United Nations as a promising driver for gender equity through improved long-term health of women and girls. Although sport-based interventions have been popularized to advance educational, social, and political development globally, little attention has been given to its impacts on health outcomes among women and girls. We undertook a scoping review of research on sport-based interventions for health among women and girls to summarize current research approaches and findings. PRISMA scoping review guidelines were observed. Online databases (PubMed, PsycINFO, Web of Science) were used to identify peer-reviewed records published through August 2022. The interventions identified (n = 4) targeted health outcomes such as gender-based violence, HIV prevention, reproductive health, and child marriage. Based on our review, we recommend four key opportunities to advance the field of sport-based interventions in addressing health equity among women and girls. In addition, we highlight promising future research directions to broaden sport engagement of women and girls, improve long-term health, and build capacity toward health equity.

Employing citizen science to enhance active and healthy ageing in urban environments

Engaging older residents in problem definition and solution-building is key to the success of place-based initiatives endeavouring to increase the age-friendliness of urban environments. This study employed the Our Voice framework, engaging older adult citizen scientists (n = 14) and community stakeholders (n = 15) across the city of Birmingham, UK. With the aim of identifying urban features impacting age friendliness and co-producing recommendations for improving local urban areas, citizen scientists participated in 12 technology-enabled walkability assessments, three in-person discussion groups, two one-to-one online discussions, and two workshops with community stakeholders. Together, citizen scientists co-produced 12 local and six city-wide recommendations. These recommendations were embedded into an implementation framework based on workshop discussions to identify age-friendly pathways in urban environments.

Our Voice in a rural community: empowering Colombian adolescents to advocate for school community well-being through citizen science

BACKGROUND

Santa Ana is home to an Afro-descendant rural population of the island of Barú in Cartagena, Colombia. While a popular area for tourism, Santa Ana's population is affected by multidimensional poverty, precarious work conditions, homelessness, broken streets and sewer systems, limited quality education, and a lack of recreation and sport spaces. While Santa Ana's Community Action Board aims to unify efforts and resources to solve these problems, the state's capacity to meet the requirements of the Board is limited.

METHODS

We evaluated the relationship between healthy lifestyles and characteristics of Santa Ana's school using the Our Voice Citizen Science Research Method. This systemic approach combines information and communication technologies with group facilitation to empower adolescents to: 1) collect and discuss data about factors in their local environments that facilitate or hinder well-being within their school community; 2) identify relevant local stakeholders who could help to address the issues identified; and 3) advocate collectively for local improvements to support increased well-being at a community level.

RESULTS

Eleven citizen scientists ages 13 to 17 years from the science club of Institución Educativa Santa Ana were recruited and together conducted 11 walks within the school to collect data about the facilitators and barriers to student well-being. They identified barriers to well-being related to school infrastructure, furniture, bathrooms, and sense of belonging. They then advocated with school stakeholders and reached agreements on concrete actions to address identified barriers, including fostering a culture among students of caring for school property and presenting their findings to the community action board. This methodology allowed the community to realize how students can become agents of change and take collective action when motivated by solution-oriented methodologies such as Our Voice. Project ripple effects, including greater empowerment and participation in collective actions by students, also were observed.

CONCLUSIONS

This study underscores the importance of the school's built environment in the well-being of students in rural areas. The Our Voice method provided the opportunity to inform school-based interventions, and promoted ripple effects that expanded productive dialogue to the community level and generated systemic actions involving actors outside of the school community.

The Dignity Project Framework: An extreme citizen science framework in occupational therapy and rehabilitation research

INTRODUCTION

Engaging citizens and patients as research partners is receiving increasing emphasis across disciplines, because citizens are untapped resources for solving complex problems. Occupational therapists are engaging in inclusive research, but not always in equitable partnership. Moving beyond inclusive research to a dignified framework for research prioritises lived experience and human rights in health research.

METHODS

Using nominal group technique over a series of three working group meetings, eight experts, including three with lived experience of disability and research, prioritised principles and steps for conducting dignified rehabilitation research in partnership with citizens with disability.

FINDINGS

Embedding transparency, accessibility and inclusion, dignified language, and authenticity throughout research were integral to maintaining dignity and safety for citizens with disability engaged in research. The Dignity Project Framework encompasses five phases, namely, (1) vision, (2) uncover, (3) discuss, (4) critical reflection, and (5) change, which address the prominent criticisms of the disability community about research and embed the principles of importance into research practice.

CONCLUSION

The framework builds on inclusive research frameworks to a human rights-based, dignified framework for extreme citizen science. Grounding disability in contemporary conceptualisations and providing a method for democratising knowledge production provide occupational therapists with a method for dignified partnership with citizens with disability.

Our Voice NOLA: Leveraging a Community Engaged Citizen Science Method to Contextualize the New Orleans Food Environment

OBJECTIVE

We employed the Our Voice citizen scientist method using a mobile application (app) to identify and contextualize neighborhood-level features influencing food access and wellbeing in New Orleans, Louisiana.

DESIGN

A three-phase, multi-method study comprised of: (1) a researcher-assisted tag-a-long neighborhood walk (referred to as a 'journey') with the Discovery Tool (DT) app to document neighborhood-level features via geo-coded photos and audio-recorded narratives; (2) a post-journey interview to enable citizen scientists to share their lived experiences; and (3) a community meeting with citizen scientists and local stakeholders.

SETTING

Various neighborhoods in New Orleans, Louisiana, USA.

PARTICIPANTS

Citizen Scientists (i.e., residents) aged 18 years and older.

MAIN OUTCOME MEASURE(S)

Features that influence food access and health behaviors.

ANALYSIS

Descriptive statistics and a thematic content analysis were conducted to assess survey and app data.

RESULTS

Citizen scientists (N = 14) captured 178 photos and 184 audio narratives. Eight major themes were identified: safety; walkability; aesthetics; amenities; food; health services; neighborhood changes; and infrastructure/city planning. The post-journey interview provided insights around the abovementioned themes. The community meeting demonstrated the willingness of citizen scientists and stakeholders to convene and discuss issues and relevant solutions.

CONCLUSIONS AND IMPLICATIONS

Findings demonstrate the ability of technology and citizen science to help better understand the complexities of New Orleans' past, present and distinct culture-and implications for food access and wellbeing in the context of trauma in an urban ecosystem.

Changes in Fruit and Vegetable Consumption and Leisure Time Physical Exercise after a Citizen Science-Based Worksite Health Promotion Program for Blue-Collar Workers

Blue-collar workers have, on average, poorer health than white-collar workers. Existing worksite health promotion programs (WHPPs) are often not successful among blue-collar workers. This study evaluates the effect of the Citizen Science-based WHPP on the targeted lifestyle behaviors among construction workers. The data of 114 participants were retrieved from questionnaires before (T0) and after (T1) the WHPP. Outcome measures were mean and categorical changes in daily fruit and vegetable intake and weekly leisure time physical exercise. Changes were tested using Wilcoxon signed rank tests and McNemar tests. No statistically significant changes were found between T0 and T1. In total, 73.7% of the participants felt involved in the WHPP. Changes in the outcome measures were not significantly different between subgroups based on age, nor in subgroups based on feelings of involvedness. The low intensity of the developed program could be an explanation for this lack of significant change. Future studies using the Citizen Science approach in an occupational setting should aim at developing a more intensified program and should test its effectiveness by comparing changes in a (randomized) controlled trial.

Eine Perspektive von Grundschulkindern auf Bedingungsfaktoren der aktiven und eigenständigen Mobilität – eine qualitative Studie

Nur wenige Kinder erreichen die Bewegungsempfehlungen der Weltgesundheitsorganisation und profitieren von den gesundheitlichen Effekten der körperlichen Aktivität. Die Förderung nicht-organisierter Bewegungsaktivitäten, wie die aktive und eigenständige Mobilität, ist ein relevanter Ansatzpunkt für Interventionen zur Bewegungsförderung bei Kindern im Grundschulalter. Ziel der vorliegenden Studie war es, hinderliche und förderliche Faktoren für die eigenständige und aktive Mobilität auf dem Schulweg zu identifizieren, aus welchen geeignete Interventionsmaßnahmen abgeleitet werden können.

Im Rahmen der Studie wurden zwölf Grundschulkinder im Alter von acht bis zehn Jahren qualitativ anhand der Photovoice-Methode zu ihrem Schulweg befragt. Basierend auf dem sozial-ökologischen Modell wurden individuelle, soziale und physische Einflussfaktoren aus den Daten extrahiert. Insbesondere die elterliche Erlaubnis, eine mangelnde fahrrad- und fußgängerfreundliche Infrastruktur und rücksichtslose motorisierte Verkehrsteilnehmer*innen hindern Kinder an einem aktiven und eigenständigen Zurücklegen des Schulwegs.

Anhand der Studie wurden vielfältige Faktoren auf unterschiedlichen sozial-ökologischen Ebenen identifiziert, welche in Interventionsmaßnahmen zur Förderung eines aktiven und eigenständigen Schulwegs berücksichtigt werden sollten. Zudem sollten Verbesserungsvorschläge der Grundschüler*innen zur Ermöglichung eines aktiven und eigenständigen Schulwegs in der Stadtplanung und -entwicklung kritisch reflektiert und berücksichtigt werden, um kindgerechte Umwelten zu schaffen.

Active and healthy ageing in urban environments: laying the groundwork for solution-building through citizen science

Urban age-friendly initiatives strive to promote active and healthy ageing by addressing urban influences that impact individuals as they age. Collaborative community partnerships with multi-level stakeholders are crucial for fostering age-friendly initiatives that can transform urban community health. Employing a citizen social science (CSS) approach, this study aimed to engage older adults and stakeholders in Birmingham, UK, to (i) identify key urban barriers and facilitators to active and healthy ageing, and (ii) facilitate collaboration and knowledge production to lay the groundwork for a citizen science project. Older adults (n = 16; mean age = 72(7.5 SD); 11 female) and community stakeholders (n = 11; 7 female) were engaged in six online group discussions, with audio recordings transcribed and thematically analysed to present key urban barrier and facilitator themes. Ageism, winter, technology and safety were barriers identified by both groups. Outdoor spaces and infrastructure, transportation, community facilities, and Covid-19 pandemic were identified as barriers and/or facilitators. Older adults identified the ageing process as a barrier and diversity of the city, health and mobility and technology as facilitators. For stakeholders, barriers were deprivation and poverty, gender differences, and ethnicity, whereas age-inclusive activities were a facilitator. Organic and active opportunities for older adults and stakeholders to connect, co-produce knowledge on urban environments and share resources presented foundations of solution-building and future collaboration. CSS effectively facilitated a range of stakeholders across local urban spaces to collaborate and co-produce ideas and solutions for enhancing local urban environments to promote active and healthy ageing.

Developing non-exercise activity thermogenesis (NEAT) through building design

Purpose

Physical inactivity has a considerable negative impact on health. Physical activity has reduced partly due to workplace and lifestyle changes, causing people to spend more time in buildings and increasing sedentary behaviour. The purpose of this paper is to address a largely untapped opportunity for designers and managers to improve building users’ health by designing buildings that raise users’ Non-Exercise Activity Thermogenesis (NEAT) levels. In this research a conceptual model was developed to assess buildings’ performance in providing NEAT-promoting opportunities through building design features and management, in relation to building users’ propensity for NEAT behaviours.

Design/methodology/approach

The conceptual model was developed by a multi-disciplinary team of researchers and data to populate the model was obtained through a survey of 75 buildings in Jakarta (Indonesia).

Findings

The presented proof-of-concept shows that the model’s “meso-scale” approach to study physical activity and building design can lead to potential improvements of NEAT levels and physical activity in buildings.

Originality/value

The review of precedent models shows that this subject has been researched at micro-scale (i.e. detailed monitoring of individuals’ movement) and macro-scale (i.e. epidemiological studies of populations’ health). The presented model is original, as it explores a “meso-scale”(i.e. building scale) that is unique.

The Role of Urban Environments in Promoting Active and Healthy Aging: A Systematic Scoping Review of Citizen Science Approaches

Promoting active and healthy aging in urban spaces requires environments with diverse, age-friendly characteristics. This scoping review investigated the associations between urban characteristics and active and healthy aging as identified by citizen science (CS) and other participatory approaches. Using a systematic scoping review procedure, 23 articles employing a CS or participatory approach (participant age range: 54-98 years) were reviewed. An inductive and deductive thematic analysis was completed to (a) identify local urban barriers and facilitators and (b) map them against the World Health Organization (WHO) Checklist of Essential Features of Age-Friendly Cities. A new Citizen Science Appraisal Tool (CSAT) was developed to evaluate the quality of CS and other participatory approaches included in the reviewed articles. A range of interconnected urban barriers and facilitators was generated by residents across the personal (e.g. perceived safety), environmental (e.g. unmaintained infrastructure), socio-cultural (e.g. cross-cultural activities), economic (e.g. affordable housing) and political (e.g. governmental support to migrant communities) domains. Mapping the barriers and facilitators to the WHO age-friendly checklist underscored the checklist's relevance and elucidated the need to explore barriers for migrant and cross-cultural communities and neighborhood development and alterations. The CSAT demonstrated strengths related to active engagement of residents and study outcomes leading to real-world implications. To advance the potential of CS to enrich our understanding of age-friendly environments, employing co-production to enhance relevance and sustainability of outcomes is an important strategy. Overall, employing CS highlighted the value of systematically capturing the experiences of older adults within studies aimed at promoting active and healthy aging.

A Scoping Review of Citizen Science Approaches in Chronic Disease Prevention

Background

Citizen science approaches, which involve members of the public as active collaborators in scientific research, are increasingly being recognized for their potential benefits in chronic disease prevention. However, understanding the potential applicability, feasibility and impacts of these approaches is necessary if they are to be more widely used. This study aimed to synthesize research that has applied and evaluated citizen science approaches in chronic disease prevention and identify key questions, gaps, and opportunities to inform future work in this field.

Methods

We searched six databases (Scopus, Medline, Embase, PsycInfo, PubMed, and CINAHL) in January 2022 to identify articles on the use of citizen science in prevention. We extracted and synthesized data on key characteristics of citizen science projects, including topics, aims and level of involvement of citizen scientists, as well as methods and findings of evaluations of these projects.

Results

Eighty-one articles reported on citizen science across a variety of health issues, predominantly physical activity and/or nutrition. Projects primarily aimed to identify problems from the perspective of community members; generate and prioritize solutions; develop, test or evaluate interventions; or build community capacity. Most projects were small-scale, and few were co-produced with policy or practice stakeholders. While around half of projects included an evaluation component, overall, there was a lack of robust, in-depth evaluations of the processes and impacts of citizen science projects.

Conclusions

Citizen science approaches are increasingly being used in chronic disease prevention to identify and prioritize community-focused solutions, mobilize support and advocacy, and empower communities to take action to support their health and wellbeing. However, to realize the potential of this approach more attention needs to be paid to demonstrating the feasibility of using citizen science approaches at scale, and to rigorous evaluation of impacts from using these approaches for the diverse stakeholders involved.

Citizen science in the community: Gaining insight in community and participant health in four deprived neighbourhoods in the Netherlands

The aim of this study was to examine if citizen science contributes to gaining insight into community health and to the health of the citizen scientists themselves. Therefore, thirteen citizens in four deprived neighbourhoods were trained as citizen scientists to conduct research in their own communities. Results showed that the citizen scientists identified forty (health related) themes in their communities. The citizen scientists reported an increase in their overall self-perceived health which, however, was not significantly demonstrated in the prequestionnaire and postquestionnaire.

Postcolonial pandemic publics: examining social media health promotion in India during the COVID-19 crisis

Affordances offered by new media platforms are perceived as revolutionary instruments for removing the inequities of access to health promotion and communication. However, the production and dissemination of health promotional material on digital platforms does not necessarily translate into uniform access across diverse demographics. This article addresses the lacuna when it comes to analyzing Health Promotion initiatives in India, with a specific focus on the governmental publicity carried out on social media during the four phases of COVID-19 national lockdown between 24 March and 31 May 2020. Our intervention examines how governmental social media health promotion in India played a key role in shaping the 'outbreak narrative' during the lockdown across different levels of social and economic privilege. Through a combination of quantitative data analysis and qualitative interview methods, this article analyzes the circulation and impact of official publicity in online and offline spaces, during the COVID-19 lockdown in India. Resultant findings allow for a comprehensive assessment of whether such publicity contributed to democratized citizen science discourses: enabling social protection measures for vulnerable majorities or potentially reified the existing privileges of the economically and socially affluent minority. We find that health promotion campaigns during a pandemic must focus on reaching the widest possible audience in the most efficient manner. Specifically, in the Indian context, health promotion through mass-media like Television and Radio, and participatory media platforms needed to be implemented in tandem with new media platforms, to achieve required engagement with vulnerable communities on key health issues.

Co-creating a local environmental epidemiology study: the case of citizen science for investigating air pollution and related health risks in Barcelona, Spain

BACKGROUND

While the health risks of air pollution attract considerable attention, both scholarly and within the general population, citizens are rarely involved in environmental health research, beyond participating as data subjects. Co-created citizen science is an approach that fosters collaboration between scientists and lay people to engage the latter in all phases of research. Currently, this approach is rare in environmental epidemiology and when co-creation processes do take place, they are often not documented. This paper describes the first stages of an ongoing co-created citizen science epidemiological project in Barcelona (Spain), that included identifying topics that citizens wish to investigate as regards air pollution and health, formulating their concerns into research questions and co-designing the study protocol. This paper also reflects key trade-offs between scientific rigor and public engagement and provides suggestions to consider when applying citizen science to environmental health studies.

METHODS

Experts created an online survey and analyzed responses with descriptive statistics and qualitative coding. A pop-up intervention was held to discuss with citizens their concerns about air pollution and health. Later on, a community meeting was organized to narrow down the research topics and list potential research questions. In an online survey, citizens were asked to vote for the research question they would like to investigate with the experts. A workshop was held to choose a study design in which citizens would like to partake to answer their preferred research question.

RESULTS

According to 488 respondents from the first survey, cognitive and mental health were the main priorities of investigation. Based on the second survey, with 27% of the votes from 556 citizens, the most popular research question was, "How does air pollution together with noise and green/blue spaces affect mental health?". The study design selected was an observational study in which citizens provide daily repeated measures of different cognitive and mental health outcomes and relate them to the air pollution concentrations.

CONCLUSIONS

Based on the co-creation activities and the results obtained, we conclude that applying citizen science in an environmental health project is valuable for researchers despite some challenges such as engaging citizens and maximizing representativity.

Enabling Better Physical Activity and Screen Time Behaviours for Adolescents from Middle Eastern Backgrounds: Semi-Structured Interviews with Parents

The unrelenting obesity pandemic in Middle Eastern (ME) adolescents living in Australia warrants culturally responsive and locally engineered interventions. Given the influence of parents on the lifestyle behaviours of adolescents, this qualitative study aimed to capture the opinions of ME parents on the barriers and enablers to sufficient physical activity and limiting screen time behaviours in adolescents. Semi-structured interviews were conducted with 26 ME parents (female) aged 35–59 years old, most of whom resided in lower socioeconomic areas (n = 19). A reflexive thematic analysis using the Theoretical Domains Framework and the Capability, Opportunity, Motivation-Behaviour model was performed for coding. Parents voiced confidence in their knowledge of the importance of physical activity and limiting screen time but were less optimistic in their ability to enable change in behaviours, especially for older adolescents without outside support. Despite adolescents having the necessary skills to engage in a wide array of sports, the parents admitted deep fears regarding the safety of the social environment and restricted their children’s independent mobility. Gender differences were noted, with parents reporting older girls expressing disinterest in sports and having limited physical opportunities to participate in sports at school. It may be that a community-based participatory framework is needed to improve physical activity opportunities and to address specific physical, social, and cultural barriers.

The effectiveness of digital interventions for increasing physical activity in individuals of low socioeconomic status: a systematic review and meta-analysis

BACKGROUND

Digital technologies such as wearables, websites and mobile applications are increasingly used in interventions targeting physical activity (PA). Increasing access to such technologies makes an attractive prospect for helping individuals of low socioeconomic status (SES) in becoming more active and healthier. However, little is known about their effectiveness in such populations. The aim of this systematic review was to explore whether digital interventions were effective in promoting PA in low SES populations, whether interventions are of equal benefit to higher SES individuals and whether the number or type of behaviour change techniques (BCTs) used in digital PA interventions was associated with intervention effects.

METHODS

A systematic search strategy was used to identify eligible studies from MEDLINE, Embase, PsycINFO, Web of Science, Scopus and The Cochrane Library, published between January 1990 and March 2020. Randomised controlled trials, using digital technology as the primary intervention tool, and a control group that did not receive any digital technology-based intervention were included, provided they had a measure of PA as an outcome. Lastly, studies that did not have any measure of SES were excluded from the review. Risk of Bias was assessed using the Cochrane Risk of Bias tool version 2.

RESULTS

Of the 14,589 records initially identified, 19 studies were included in the final meta-analysis. Using random-effects models, in low SES there was a standardised mean difference (SMD (95%CI)) in PA between intervention and control groups of 0.06 (- 0.08,0.20). In high SES the SMD was 0.34 (0.22,0.45). Heterogeneity was modest in both low (I2 = 0.18) and high (I2 = 0) SES groups. The studies used a range of digital technologies and BCTs in their interventions, but the main findings were consistent across all of the sub-group analyses (digital interventions with a PA only focus, country, chronic disease, and duration of intervention) and there was no association with the number or type of BCTs.

DISCUSSION

Digital interventions targeting PA do not show equivalent efficacy for people of low and high SES. For people of low SES, there is no evidence that digital PA interventions are effective, irrespective of the behaviour change techniques used. In contrast, the same interventions in high SES participants do indicate effectiveness. To reduce inequalities and improve effectiveness, future development of digital interventions aimed at improving PA must make more effort to meet the needs of low SES people within the target population.

Testing the effectiveness of community-engaged citizen science to promote physical activity, foster healthier neighborhood environments, and advance health equity in vulnerable communities: The Steps for Change randomized controlled trial design and methods

While low-income midlife and older adults are disproportionately affected by non-communicable diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. The specific aim of the Steps for Change cluster-randomized controlled trial is to compare systematically the initial (one-year) and sustained (two-year) multi-level impacts of an evidence-based person-level physical activity intervention (Active Living Every Day [ALED] and age-relevant health education information), versus the ALED program in combination with a novel neighborhood-level citizen science intervention called Our Voice. The study sample (N = 300) consists of insufficiently active adults ages 40 years and over living in or around affordable senior public housing settings. Major study assessments occur at baseline, 12, and 24 months. The primary outcome is 12-month change in walking, and secondary outcomes include other forms of physical activity, assessed via validated self-report measures supported by accelerometry, and physical function and well-being variables. Additional intervention impacts are assessed at 24 months. Potential mediators and moderators of intervention success will be explored to better determine which subgroups do best with which type of intervention. Here we present the study design and methods, including recruitment strategies and yields. TRIAL REGISTRATION: clinicaltrial.gov Identifier = NCT03041415.

Engaging citizen scientists to build healthy park environments in Colombia

Colombia's Recreovía program offers community-based free physical activity (PA) classes in parks. We evaluated built and social environmental factors influencing Recreovía local park environments, and facilitated a consensus-building and advocacy process among community members, policymakers and academic researchers aimed at improving uptake and impact of the Recreovía program. We used a mixed-methods approach, with individual and contextual PA measurements and a resident-enabled participatory approach (the Our Voice citizen science engagement model). Recreovía participants were likely to be women meeting PA recommendations, and highly satisfied with the Recreovía classes. Reported facilitators of the Recreovía included its role in enhancing social and individual well-being through PA classes. Reported barriers to usage were related to park maintenance, cleanliness and safety. The Our Voice process elicited community reflection, empowerment, advocacy and action. Our Voice facilitated the interplay among stakeholders and community members to optimize the Recreovía program as a facilitator of active living, and to make park environments more welcoming.

Using citizen science to empower older adults to improve a food security initiative in Australia

Food security is an increasing problem for older adults who are living longer and having to stretch their resources further. Initiatives such as subsidized community market days are increasingly important in bolstering food security amongst these groups but there have been few attempts to understand these initiatives from the perspective of community members. This exploratory study examined the utility of a novel citizen science approach to engage older adults in evaluating and improving a local food security initiative. Using the Our Voice methodology, citizen scientists recorded their perceptions of their local Market Day via photographs and audio narratives. Thirteen citizen scientists captured 127 photographs and 125 commentaries. Citizen scientists participated in workshops to discuss, code and synthesize their data, and used their findings to advocate for change. A number of improvements to the Market Day were made by key stakeholders on the basis of citizen scientist recommendations, including improving the processes for sourcing and storing food and changing the layout to improve access. This study demonstrates that citizen science is a useful and feasible approach to engaging community members in capturing data and advocating for change to ensure that local initiatives meet the needs of communities.

Built environment in programs to promote physical activity among Latino children and youth living in the United States and in Latin America

To prevent obesity among Latino youth in the United States and Latin America, it is necessary to understand the specific context and interplay of physical activity (PA) and the built environment (BE). This paper aims to advance the research agenda of BE and PA for obesity prevention in Latin America and among Latino youth in the United States by (1) identifying environmental indicators to inform the design of interventions and policy, (2) identifying interdisciplinary methodological approaches for the study of the complex association between BE and PA, and (3) presenting case studies of PA-promoting BE programs. A group of U.S. and Latin American scientists collaboratively worked to propose innovative indicators of the BE, methodological approaches for the study of the complex association between BE and PA, and review case studies of PA-promoting BE programs in both regions. The results identified gaps in knowledge, proposed environmental indicators (e.g., landscape, street design, mobility patterns, and crime and safety), reviewed methodological approaches (social network analysis, citizen science methods), and case studies illustrating PA-promoting BE programs (i.e., play streets, active school transport, and school setting interventions). The obesity prevention among Latino and Latin American youth requires advanced research on BE and PA addressing context-specific priorities and exchanging lessons learned.

Measurement challenges for childhood obesity research within and between Latin America and the United States

Childhood obesity is a major public health challenge across Latin America and the United States. Addressing childhood obesity depends on valid, reliable, and culturally sensitive measurements. Such progress within and between countries of the Americas could be enhanced through better measurement across different age groups, different countries, and in sending and receiving communities. Additionally, better and more comparable measurements could accelerate cross-border collaboration and learning. Here, we present (1) frameworks that influenced our perspectives on childhood obesity and measurement needs across the Americas; (2) a summary of resources and guidance available concerning measurement and adaptation of measures for childhood obesity research; and (3) three major areas that present challenges and opportunities for measurement advances related to childhood obesity, including parental behavior, acculturation, and the potential to incorporate ethnographic methods to identify critical factors related to economics and globalization. Progress to reduce childhood obesity across the Americas could be accelerated by further transnational collaboration aimed at improving measurement for better surveillance, intervention development and evaluation, implementation research, and evaluation of natural experiments. Additionally, there is a need to improve training related to measurement and for improving access to valid and reliable measures in Spanish and other languages common in the Americas.

Exploring University Age-Friendliness Using Collaborative Citizen Science

Background and Objectives

Since the launch of Dublin City University’s Age-Friendly University (AFU) Initiative in 2012, relatively little empirical research has been published on its feasibility or implementation by institutions of higher learning. This article describes how collaborative citizen science—a research method where professional researchers and community members work together across multiple stages of the research process (e.g., data collection, analysis, and/or knowledge mobilization) to investigate an issue—was used to identify barriers and supports to university age-friendliness at the University of Manitoba (UofM) in Canada.

Research Design and Methods

Ten citizen scientists each completed 1 data collection walk around the UofM campus and used a tablet application to document AFU barriers and supports via photographs and accompanying audio commentaries. The citizen scientists and university researchers then worked together in 2 analysis sessions to identify AFU priority areas and brainstorm recommendations for institutional change. These were then presented to a group of interested university stakeholders.

Results

The citizen scientists collected 157 photos documenting AFU barriers and supports on campus. Accessibility, signage, and transportation were identified as being the most pressing issues for the university to address to improve overall age-friendliness.

Discussion and Implications

We suggest that academic institutions looking to complete assessments of their age-friendliness, particularly those exploring physical barriers and supports, could benefit from incorporating older citizen scientists into the process of collecting, analyzing, and mobilizing findings.

Community-Based Approaches to Reducing Health Inequities and Fostering Environmental Justice through Global Youth-Engaged Citizen Science

Growing socioeconomic and structural disparities within and between nations have created unprecedented health inequities that have been felt most keenly among the world's youth. While policy approaches can help to mitigate such inequities, they are often challenging to enact in under-resourced and marginalized communities. Community-engaged participatory action research provides an alternative or complementary means for addressing the physical and social environmental contexts that can impact health inequities. The purpose of this article is to describe the application of a particular form of technology-enabled participatory action research, called the Our Voice citizen science research model, with youth. An overview of 20 Our Voice studies occurring across five continents indicates that youth and young adults from varied backgrounds and with interests in diverse issues affecting their communities can participate successfully in multiple contributory research processes, including those representing the full scientific endeavor. These activities can, in turn, lead to changes in physical and social environments of relevance to health, wellbeing, and, at times, climate stabilization. The article ends with future directions for the advancement of this type of community-engaged citizen science among young people across the socioeconomic spectrum.

A systematic review of empirical and simulation studies evaluating the health impact of transportation interventions

Urban transportation is an important determinant of health and environmental outcomes, and therefore essential to achieving the United Nation's Sustainable Development Goals. To better understand the health impacts of transportation initiatives, we conducted a systematic review of longitudinal health evaluations involving: a) bus rapid transit (BRT); b) bicycle lanes; c) Open Streets programs; and d) aerial trams/cable cars. We also synthesized systems-based simulation studies of the health-related consequences of walking, bicycling, aerial tram, bus and BRT use. Two reviewers screened 3302 unique titles and abstracts identified through a systematic search of MEDLINE (Ovid), Scopus, TRID and LILACS databases. We included 39 studies: 29 longitudinal evaluations and 10 simulation studies. Five studies focused on low- and middle-income contexts. Of the 29 evaluation studies, 19 focused on single component bicycle lane interventions; the rest evaluated multi-component interventions involving: bicycle lanes (n = 5), aerial trams (n = 1), and combined bicycle lane/BRT systems (n = 4). Bicycle lanes and BRT systems appeared effective at increasing bicycle and BRT mode share, active transport duration, and number of trips using these modes. Of the 10 simulation studies, there were 9 agent-based models and one system dynamics model. Five studies focused on bus/BRT expansions and incentives, three on interventions for active travel, and the rest investigated combinations of public transport and active travel policies. Synergistic effects were observed when multiple policies were implemented, with several studies showing that sizable interventions are required to significantly shift travel mode choices. Our review indicates that bicycle lanes and BRT systems represent promising initiatives for promoting population health. There is also evidence to suggest that synergistic effects might be achieved through the combined implementation of multiple transportation policies. However, more rigorous evaluation and simulation studies focusing on low- and middle-income countries, aerial trams and Open Streets programs, and a more diverse set of health and health equity outcomes is required.

Urban Transformations and Health: Methods for TrUST-a Natural Experiment Evaluating the Impacts of a Mass Transit Cable Car in Bogotá, Colombia

Background: Cable cars provide urban mobility benefits for vulnerable populations. However, no evaluation has assessed cable cars' impact from a health perspective. TransMiCable in Bogotá, Colombia, provides a unique opportunity to (1) assess the effects of its implementation on the environmental and social determinants of health (microenvironment pollution, transport accessibility, physical environment, employment, social capital, and leisure time), physical activity, and health outcomes (health-related quality of life, respiratory diseases, and homicides); and (2) use citizen science methods to identify, prioritize, and communicate the most salient negative and positive features impacting health and quality of life in TransMiCable's area, as well as facilitate a consensus and advocacy-building change process among community members, policymakers, and academic researchers.

Methods: TrUST (In Spanish: Transformaciones Urbanas y Salud: el caso de TransMiCable en Bogotá) is a quasi-experimental study using a mixed-methods approach. The intervention group includes adults from Ciudad Bolívar, the area of influence of TransMiCable. The control group includes adults from San Cristóbal, an area of future expansion for TransMiCable. A conceptual framework was developed through group-model building. Outcomes related to environmental and social determinants of health as well as health outcomes are assessed using questionnaires (health outcomes, physical activity, and perceptions), secondary data (crime and respiratory outcomes) use of portable devices (air pollution exposure and accelerometry), mobility tracking apps (for transport trajectories), and direct observation (parks). The Stanford Healthy Neighborhood Discovery Tool is being used to capture residents' perceptions of their physical and social environments as part of the citizen science component of the investigation.

Discussion: TrUST is innovative in its use of a mixed-methods, and interdisciplinary research approach, and in its systematic engagement of citizens and policymakers throughout the design and evaluation process. This study will help to understand better how to maximize health benefits and minimize unintended negative consequences of TransMiCable.

Employing Participatory Citizen Science Methods to Promote Age-Friendly Environments Worldwide

The trajectory of aging is profoundly impacted by the physical and social environmental contexts in which we live. While “top–down” policy activities can have potentially wide impacts on such contexts, they often take time, resources, and political will, and therefore can be less accessible to underserved communities. This article describes a “bottom–up”, resident-engaged method to advance local environmental and policy change, called Our Voice, that can complement policy-level strategies for improving the health, function, and well-being of older adults. Using the World Health Organization’s age-friendly cities global strategy, we describe the Our Voice citizen science program of research that has specifically targeted older adults as environmental change agents to improve their own health and well-being as well as that of their communities. Results from 14 Our Voice studies that have occurred across five continents demonstrate that older adults can learn to use mobile technology to systematically capture and collectively analyze their own data. They can then successfully build consensus around high-priority issues that can be realistically changed and work effectively with local stakeholders to enact meaningful environmental and policy changes that can help to promote healthy aging. The article ends with recommended next steps for growing the resident-engaged citizen science field to advance the health and welfare of all older adults.

A citizen science approach to determine perceived barriers and promoters of physical activity in a low-income South African community

The study's objective was to assess the feasibility of using citizen science to identify and address physical activity (PA) barriers in a low-income South African community. We purposively selected as citizen scientists, eleven participants (21-45 years) from a cohort study who expressed interest in becoming physically active or were already active. They used the Stanford Neighborhood Discovery Tool mobile application to take photos and provide audio narratives of factors in their community that were barriers to or facilitated PA. Thereafter, in a facilitated workshop, citizen scientists thematically reviewed their findings, prioritised issues and proffered potential solutions. Researchers also thematically coded these data. PA levels were measured using standard questionnaires. None of the citizen scientists owned a car, and their PA was either work- or transport-related. Themes identified as priorities that hindered citizen scientists' PA were dirt, sidewalks appropriated by vendors or homeowners, parks and gym vandalisation, and personal safety fears. Access to stadiums and parks enabled PA. Citizen scientists identified their local councillors and street committee chairpersons as fundamental for advocacy for a PA-friendly environment. Low-income community members can be empowered to gather meaningful data using mobile technology and work together to identify potential solutions for promoting PA-friendly environments.

Review of Geospatial Technology for Infectious Disease Surveillance: Use Case on COVID-19

This paper discusses on the increasing relevancy of geospatial technologies such as geographic information system (GIS) in the public health domain, particularly for the infectious disease surveillance and modelling strategies. Traditionally, the disease mapping tasks have faced many challenges—(1) authors rarely documented the evidence that were used to create map, (2) before evolution of GIS, many errors aroused in mapping tasks which were expanded extremely at global scales, and (3) there were no fidelity assessment of maps which resulted in inaccurate precision. This study on infectious diseases geo-surveillance is divided into four broad sections with emphasis on handling geographical and temporal issues to help in public health decision-making and planning policies: (1) geospatial mapping of diseases using its spatial and temporal information to understand their behaviour across geography; (2) the citizen’s involvement as volunteers in giving health and disease data to assess the critical situation for disease’s spread and prevention in neighbourhood effect; (3) scientific analysis of health-related behaviour using mathematical epidemiological and geo-statistical approaches with (4) capacity building program. To illustrate each theme, recent case studies are cited and case studies are performed on COVID-19 to demonstrate selected models.

Charting a future for Canada's first Age-Friendly University (AFU)

Situated within a Canadian context, but with implications for a broad range of institutional settings, this paper describes the events that preceded the adoption of the Age-Friendly University (AFU) framework at the University of Manitoba (U of M), as well as the specific strategies being employed within the university to assess and encourage age-friendliness. These include: a) the university's Centre on Aging and its mandate to foster interdisciplinary age-related research and community dialogue, b) the creation of an interdisciplinary AFU committee and several working groups, c) innovative research projects that have assessed university age-friendliness from a variety of stakeholder perspectives, and d) an interactive undergraduate course activity being used to educate students about AFU features. Present and future AFU challenge areas and potential solutions are discussed.

Enhancing safe routes to school programs through community-engaged citizen science: two pilot investigations in lower density areas of Santa Clara County, California, USA

BACKGROUND

While promoting active commuting to school can positively affect children's daily physical activity levels, effectively engaging community members to maximize program impact remains challenging. We evaluated the initial utility of adding a technology-enabled citizen science engagement model, called Our Voice, to a standard Safe Routes to School (SRTS) program to enhance program engagement activities and student travel mode behavior.

METHODS

In Investigation 1, a prospective controlled comparison design was used to compare the initial year of the Santa Clara County Public Health Department's SRTS program, with and without the Our Voice engagement model added, in two elementary schools in Gilroy, California, USA. School parents served as Our Voice citizen scientists in the SRTS + Our Voice school. In Investigation 2, the feasibility of the combined SRTS + Our Voice methods was evaluated in a middle school in the same district using students, rather than adults, as citizen scientists. Standard SRTS program engagement measures and student travel mode tallies were collected at the beginning and end of the school year for each school.

RESULTS

In the elementary school investigation (Investigation 1), the SRTS + Our Voice elementary school held twice as many first-year SRTS planning/encouragement events compared to the SRTS-Alone elementary school, and between-school changes in walking/biking to school rates favored the SRTS + Our Voice school (increases of 24.5% vs. 2.6%, P < .001). The Investigation 2 results supported the feasibility of using students to conduct SRTS + Our Voice in a middle school-age population.

CONCLUSIONS

The findings from this first-generation study indicated that adding a technology-enabled citizen science process to a standard elementary school SRTS program was associated with higher levels of community engagement and walking/biking to school compared to SRTS alone. The approach was also found to be acceptable and feasible in a middle school setting.

Conceptualizing structural change in health promotion: why we still need to know more about theory

As recently discussed in the public health literature, many questions concerning 'structural' approaches in health promotion seem to remain unanswered. We argue that, before attempting to provide answers, it is essential to clarify the underlying theoretical assumptions in order to arrive at the right questions one should ask. To this end, we introduce into the current debate an existing theoretical framework that helps conceptualize structural and individual aspects of health promotion interventions at different levels of action. Using an example from the field of physical activity promotion, we illustrate how an integrated framework can help researchers and health promoters rethink important issues and design better interventions. In particular, such an approach may help overcome perceived distinctions between different types of approaches, re-conceptualize ideas about the effectiveness of interventions, and appropriately address issues of health disparities.

Older Adults Using Our Voice Citizen Science to Create Change in Their Neighborhood Environment

Physical activity, primarily comprised of walking in older adults, confers benefits for psychological health and mental well-being, functional status outcomes and social outcomes. In many communities, however, access to physical activity opportunities are limited, especially for older adults. This exploratory study engaged a small sample (N = 8) of adults aged 65 or older as citizen scientists to assess and then work to improve their communities. Using a uniquely designed mobile application (the Stanford Healthy Neighborhood Discovery Tool), participants recorded a total of 83 geocoded photos and audio narratives of physical environment features that served to help or hinder physical activity in and around their community center. In a facilitated process the citizen scientists then discussed, coded and synthesized their data. The citizen scientists then leveraged their findings to advocate with local decision-makers for specific community improvements to promote physical activity. These changes focused on: parks/playgrounds, footpaths, and traffic related safety/parking. Project results suggest that the Our Voice approach can be an effective strategy for the global goals of advancing rights and increasing self-determination among older adults.

Unique Views on Obesity-Related Behaviors and Environments: Research Using Still and Video Images

OBJECTIVES

To document challenges to and benefits from research involving the use of images by capturing examples of such research to assess physical activity- or nutrition-related behaviors and/or environments.

METHODS

Researchers (i.e., key informants) using image capture in their research were identified through knowledge and networks of the authors of this paper and through literature search. Twenty-nine key informants completed a survey covering the type of research, source of images, and challenges and benefits experienced, developed specifically for this study.

RESULTS

Most respondents used still images in their research, with only 26.7% using video. Image sources were categorized as participant generated (n = 13; e.g., participants using smartphones for dietary assessment), researcher generated (n = 10; e.g., wearable cameras with automatic image capture), or curated from third parties (n = 7; e.g., Google Street View). Two of the major challenges that emerged included the need for automated processing of large datasets (58.8%) and participant recruitment/compliance (41.2%). Benefit-related themes included greater perspectives on obesity with increased data coverage (34.6%) and improved accuracy of behavior and environment assessment (34.6%).

CONCLUSIONS

Technological advances will support the increased use of images in the assessment of physical activity, nutrition behaviors, and environments. To advance this area of research, more effective collaborations are needed between health and computer scientists. In particular development of automated data extraction methods for diverse aspects of behavior, environment, and food characteristics are needed. Additionally, progress in standards for addressing ethical issues related to image capture for research purposes is critical.
