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

A rapid review of digital approaches for the participatory development of health-related interventions

Objectives

Using participatory approaches to design health interventions is promising, and the ongoing digitalization has enabled the development of diverse digital formats for this purpose. These digital formats bring forth distinct advantages and challenges that should be carefully considered. This rapid review aims to present an overview of digital formats employed in participatory health intervention development and their reported benefits and barriers.

Design

A qualitative rapid review was conducted, following recommendations by the Cochrane Rapid Reviews Methods Group. The literature search was carried out in October 2022 and encompassed the PubMed, Embase, PsycINFO, and Cochrane CENTRAL databases. Studies were included if they were published in 2010 or later and reported the development of a health-related intervention employing digital formats in the participatory process.

Results

A total of 22 studies were included. We identified three types of digital formats used for participatory health intervention development: web-based participatory formats (n = 14), digital participatory visual formats (n = 5), and digital participatory mapping (n = 3). The reported benefits of applying digital formats included enhanced participant anonymity, increased time and cost efficiency, and more flexibility regarding scheduling and extent of participation. Among the reported barriers were sufficient internet connectivity, required technical skills, and online fatigue.

Conclusion

The review shows a variety of digital formats employed to develop participatory health interventions. Yet, these methods are primarily digital adaptations of pre-existing analog formats. Innovative digital approaches involving, for example, virtual reality devices remain largely unused. The review also revealed a need for establishing shared terminology and reporting standards to facilitate communication, comparison, and synthesis of findings in this evolving area of research.

Citizen Science Studies in Nursing: A Systematic Review

BACKGROUND

Citizen science is a research approach wherein citizens actively participate alongside professionals in some or all stages of the research process. The bidirectional benefits it generates, especially in the field of health, including empowerment, new hypotheses, and results, and addressing issues truly important to society, justify the necessity to establish a common framework and address barriers to ensure a fruitful evolution of this new approach within nursing research. The aim was to analyze nursing projects with a citizen science focus that have been conducted.

METHODS

PRISMA guidelines were employed to conduct a systematic review. Searches were conducted on PubMed, CINHAL, LILACS, IBECS, and Cochrane. Following the identification and screening process, 13 studies were included. The quality of the articles was assessed using the Joanna Brigg Institute (JBI) critical appraisal checklist and the quality of citizen science research using the Citizen Science Appraisal Tool.

RESULTS

Citizen science studies in nursing were notably recent (2017-2023). Five research areas were identified, with environmental health being the most predominant. Multiple tools, both technological and traditional, were utilized, with the "Photovoice" and "Our Voice" methodologies being prominent. Citizen participation was limited to data collection and analysis in 7 out of the 13 studies, with most studies working with small samples. Findings regarding the application of this practice were positive, but no study exceeded 26 points on the CSAT scale to be considered high quality in citizen science.

CONCLUSIONS

Citizen science can be a promising approach within the field of nursing. There is a need to increase individual participation to fully realize the potential bidirectional benefits. It is imperative to establish a common theoretical framework and continue working on the development of this methodology within nursing.

Examining the referral of patients with elevated blood pressure to health resources in an under-resourced community in South Africa

BACKGROUND

Low-and-middle income countries face a disproportionate burden of non-communicable diseases (NCDs) that threaten to overwhelm under-resourced health systems. Community health workers (CHWs) can promote NCD prevention, reach patients, and connect them to local community health resources; however, little has been done to examine how referrals to these resources are utilized by community members. The purpose of this study is to examine the use of referrals to community-based health resources and investigate the factors influencing patient utilization of referrals connecting them to appropriate health resources for elevated blood pressure (BP).

METHODS

CHWs conducted home visits, which included BP screening and brief counseling, with community members in Soweto, South Africa. Participants with elevated (systolic BP: 121-139/ diastolic BP: 81-89 mmHg) or high (≥ 140/90 mmHg) BP were referred to either a local, community-based physical activity (PA) program managed by a non-governmental organization or local health clinics. The number of participants that received and utilized their referrals was tracked. Follow-up interviews were conducted with individuals given a referral who: (1) went to the PA program, (2) did not go to the PA program, (3) went to a clinic, and (4) did not go to a clinic. Interviews were transcribed and analyzed to identify common themes and differences between groups regarding their decisions to utilize the referrals.

RESULTS

CHWs visited 1056 homes, with 1001 community members consenting to the screening; 29.2% (n = 292) of adults were classified as having optimal BP (≤120/80 mmHg), 35.8% (n = 359) had elevated BP, and 35.0% (n = 350) had high BP. One hundred and seventy-three participants accepted a referral to the PA program with 46 (26.6%) enrolling. Five themes emerged from the interviews: (1) prior knowledge and thoughts on BP, (2) psychosocial factors associated with BP control, (3) perception about receiving the referral, (4) contextual factors influencing referral utilization, and (5) perceived benefits of utilizing the referral.

CONCLUSION

CHWs can successfully increase community members' access to health resources by providing appropriate referrals. However, greater attention needs to address community members' barriers and hesitancy to utilize health resources.

Implementing and Evaluating Community Health Worker-Led Cardiovascular Disease Risk Screening Intervention in Sub-Saharan Africa Communities: A Participatory Implementation Research Protocol

The increasing burden of non-communicable diseases (NCDs), particularly cardiovascular diseases (CVD) in low- and middle-income countries (LMICs) poses a considerable threat to public health. Community-driven CVD risk screening, referral and follow-up of those at high CVDs risk is essential to supporting early identification, treatment and secondary prevention of cardiovascular events such as stroke and myocardial infarction. This protocol describes a multi-country study that aims to implement and evaluate a community health worker (CHW)-led CVD risk screening programme to enhance referral linkages within the local primary care systems in sub-Saharan Africa (SSA), using a participatory implementation science approach. The study builds upon a prior community-driven multicentre study conducted by the Collaboration for Evidence-based Health Care and Public Health in Africa (CEBHA+). This is a participatory implementation research. The study will leverage on the CVD risk citizen science pilot studies conducted in the four selected CEBHA+ project countries (viz. Ethiopia, Rwanda, Malawi, and South Africa). Through planned engagements with communities and health system stakeholders, CHWs and lay health worker volunteers will be recruited and trained to screen and identify persons that are at high risk of CVD, provide referral services, and follow-up at designated community health clinics. In each country, we will use a multi-stage random sampling to select and then screen 1000 study participants aged 35-70 years from two communities (one rural and one urban). Screening will be done using a simple validated non-laboratory-based CVD risk assessment mobile application. The RE-AIM model will be used in evaluating the project implementation outcomes, including reach, fidelity, adoption and perceived effectiveness. Developing the capacities of CHWs and lay health worker volunteers in SSA to support population-based, non-invasive population-based CVD risk prevention has the potential to impact on early identification, treatment and secondary prevention of CVDs in often under-resourced communities. Using a participatory research approach to implementing mobile phone-based CHW-led CVD risk screening, referral and follow-up in SSA will provide the evidence needed to determine the effectiveness of CVD risk screening and the potential for scaling up in the wider region.

The "Our Voice" Method: Participatory Action Citizen Science Research to Advance Behavioral Health and Health Equity Outcomes

Citizen science research that more fully engages the community can systematically involve people from under-resourced groups to create practical health-enhancing improvements across physical, social and food environments. Exemplary health equity-focused outcomes include key health behaviors (e.g., healthy eating or physical activity) and community-level changes (e.g., public transit to food shops) that are central to health promotion while being demonstrably impacted by local environmental contexts. Yet, few examples of this approach are readily available for application within complex, community-based settings. In this paper, we present the Our Voice (OV) four-step method to demonstrate an integrated participatory citizen science approach and its usability for action-focused researchers and community health practitioners. In addition, we present a summary of the major research, processes, and community outcomes, with examples drawn from nutrition and healthy food access areas, among others. Finally, we explore the hallmark features of the OV method that effectively engage citizen scientists, empowering action and fostering solution-building across social and environmental structures impacting community health. Expanding research that marries participatory research philosophies with innovative citizen science methods, supported by systematic data collection, visualization, and delivery technologies, in turn provides a powerful toolkit for tackling local to global health equity challenges.

Estimating the changing burden of disease attributable to low levels of physical activity in South Africa for 2000, 2006 and 2012

Background. Physical activity is associated with a lower risk of cardiovascular outcomes, certain cancers and diabetes. The previous South African Comparative Risk Assessment (SACRA1) study assessed the attributable burden of low physical activity for 2000, but updated estimates are required, as well as an assessment of trends over time.Objective. To estimate the national prevalence of physical activity by age, year and sex and to quantify the burden of disease attributable to low physical activity in South Africa (SA) for 2000, 2006 and 2012.Methods. Comparative risk assessment methodology was used. Physical activity was treated as a categorical variable with four categories, i.e. inactive, active, very active and highly active. Prevalence estimates of physical activity levels, representing the three different years, were derived from two national surveys. Physical activity estimates together with the relative risks from the Global Burden of Disease, Injuries, and Risk Factors (GBD) 2016 study were used to calculate population attributable fractions due to inactive, active and very active levels of physical activity relative to highly active levels considered to be the theoretical minimum risk exposure (>8 000 metabolic equivalent of time (MET)-min/wk), in accordance with the GBD 2016 study. These were applied to relevant disease outcomes sourced from the Second National Burden of Disease Study to calculate attributable deaths, years of life lost, years lived with disability and disability adjusted life years (DALYs). Uncertainty analysis was performed using Monte Carlo simulation.Results. The prevalence of physical inactivity (<600 METS) decreased by 16% and 8% between 2000 and 2012 for females and males, respectively. Attributable DALYs due to low physical activity increased between 2000 (n=194 284) and 2006 (n=238 475), but decreased thereafter in 2012 (n=219 851). The attributable death age-standardised rates (ASRs) declined between 2000 and 2012 from 60/100 000 population in 2000 to 54/100 000 population in 2012. Diabetes mellitus type 2 displaced ischaemic heart disease as the largest contributor to attributable deaths, increasing from 31% in 2000 to 42% in 2012.Conclusions. Low physical activity is responsible for a large portion of disease burden in SA. While the decreased attributable death ASR due to low physical activity is encouraging, this burden may be lowered further with an additional reduction in the overall prevalence of physical inactivity, in particular. It is concerning that the attributable burden for diabetes mellitus is growing, which suggests that existing non-communicable disease policies need better implementation, with ongoing surveillance of physical activity, and population- and community-based interventions are required in order to reach set targets.

Citizen Science Approach to Home Radon Testing, Environmental Health Literacy and Efficacy

Exposure to radon is a leading cause of lung cancer worldwide. However, few test their homes for radon. There is a need to increase access to radon testing and decrease radon exposure. This longitudinal, mixed-methods study using a citizen science approach recruited and trained a convenience sample of 60 non-scientist homeowners from four rural Kentucky counties to test their homes for radon using a low-cost continuous radon detector, report back findings, and participate in a focus group to assess their testing experience. The aim was to evaluate changes in environmental health literacy (EHL) and efficacy over time. Participants completed online surveys at baseline, post-testing, and 4-5 months later to evaluate EHL, response efficacy, health information efficacy, and self-efficacy related to radon testing and mitigation. Mixed modeling for repeated measures evaluated changes over time. Citizen scientists reported a significant increase in EHL, health information efficacy, and radon testing self-efficacy over time. While there was a significant increase in citizen scientists' confidence in their perceived ability to contact a radon mitigation professional, there was no change over time in citizen scientists' beliefs that radon mitigation would reduce the threat of radon exposure, nor was there a change in their capacity to hire a radon mitigation professional. Further research is needed to understand the role of citizen science in home radon mitigation.

Exploring Female University Students' Participation in Physical Activity in Saudi Arabia: A Mixed-Methods Study

Background

The importance of physical activity in improving physical and mental health has been emphasized in many studies. Researchers in Saudi Arabia have reported an increase in physical inactivity among Saudis, especially among University female population. Current efforts in the field in Saudi Arabia have yet to explore barriers and facilitators that influence female University student's participation in physical activity. This study aims to provide an assessment of the situation regarding physical activity among female University students in Saudi Arabia.

Methods

This mixed method study preceded a participatory action research initiative. The first part of the mixed method consisted of a cross-sectional survey of 375 female University students in Saudi Arabia who completed the short form of the International Physical Activity Questionnaire. The second part consisted of semi-structured, in-depth interviews with 14 female University students and 16 female exercise trainers.

Results

Results showed that most participants (91%) spent more time in walking activity compared to moderate (66%) and vigorous activity (57%) for at least 10 min at a time over a period of 7 days. Results showed that 70% of participants did not meet the WHO recommendation of 150 min per week of moderate activity, while around 62% of participants did not meet the WHO recommendation of 75 min per week of vigorous activity. Barriers to participation included limited facilities for physical activities, academic workload, gender role, and the need to adhere to cultural standards. Facilitators included valuing positive results, general health concerns, and family support.

Conclusion

Knowledge gained from this study might support organizations and public health authorities to develop physical activity interventions that better address Saudi women's perceived needs. These findings are an important contribution to current knowledge in light of recent advances in women's rights in Saudi Arabia.

A pilot study on the feasibility of testing residential tap water in North Carolina: implications for environmental justice and health

BACKGROUND

In 2015 alone, community water systems serving about 21 million Americans violated the United States Environmental Protection Agency's (US-EPA) water quality standards. While water at community treatment and distribution centers is regularly monitored and tested, little is known about pollutants in the water systems at the household level.

AIMS

This pilot study assessed the feasibility of (1) testing for the presence and concentration of 14 contaminants and physicochemical parameters in household tap water in a low-income neighborhood and (2) using community engagement for recruitment and citizen science approaches to data collection.

METHODS

We used a multistage approach that included geo-mapping to delineate testing sites, community engagement for recruitment and citizen science approaches to increase the response rate. We used a 14-in-one dipstick test designed to measure trace amounts of heavy metals, non-metallic elements, and physicochemical water properties in drinking water in a sample of 70 homes.

RESULTS

In 50%, 25%, and 7% of water samples tested, the concentration of mercury, lead, and chromium, respectively, were higher than US-EPA drinking water standards. Citizen science approaches were effective for increasing response rates and low-income household participation in water quality testing.

SIGNIFICANCE

The overlap between poverty, older homes, and high concentrations of potentially toxic metals in drinking water presents concerns for community health. Our pilot community engagement and citizen science approaches are likely scalable and would be of benefit to both the scientific community and to municipalities with constrained budgets. Future studies may examine the role of the principles of environmental justice in the distribution and prevalence of toxic elements in drinking water.

The Role of Citizen Science in Promoting Health Equity

While there are many definitions of citizen science, the term usually refers to the participation of the general public in the scientific process in collaboration with professional scientists. Citizen scientists have been engaged to promote health equity, especially in the areas of environmental contaminant exposures, physical activity, and healthy eating. Citizen scientists commonly come from communities experiencing health inequities and have collected data using a range of strategies and technologies, such as air sensors, water quality kits, and mobile applications. On the basis of our review, and to advance the field of citizen science to address health equity, we recommend (a) expanding the focus on topics important for health equity, (b) increasing the diversity of people serving as citizen scientists, (c) increasing the integration of citizen scientists in additional research phases, (d) continuing to leverage emerging technologies that enable citizen scientists to collect data relevant for health equity, and (e) strengthening the rigor of methods to evaluate impacts on health equity. Expected final online publication date for the Annual Review of Public Health, Volume 43 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Citizen Science in Sweden’s Stigmatized Neighborhoods

Based on the synthesis of outside versus inside perspectives, this paper weighs the positive attributes of the so-called deprived place against its negative media image. Applying the concept of territorial stigmatization, small-scale citizen science was conducted to gain a unique understanding of the Swedish neighborhood from within. With the United Nations’ Sustainable Development Goal 11 in mind, this approach enables researchers to reach otherwise difficult to access young urban outcasts and probe the potential to overcome their community’s lack of political influence. An overlap between local media narratives and urban outcasts’ perceptions of “drug and crime” and “football and school” was revealed. Yet, this first-generation study also painted a somewhat different picture of the stigmatized neighborhood, supplying new insights about places that matter most for marginalized young males. In this Swedish case, their pictures revealed that the local corner market, football court and youth club act as an antidote for the effects of stigmatization. This Our Voice citizen science initiative proved to be a good measure of two communities’ abilities to withstand stigmatization, which is either tainted by false perceptions from the outside or weakened by crime from within. Finally, attempting to bypass structural discrimination, citizen scientists’ findings and researchers’ conclusions were made available to students, colleagues and guests at a poster presentation hosted by Mälardalen University and to concerned politicians from Eskilstuna City Hall as well as the broader public via a local Swedish television station.

A Novel Model for Generating Creative, Community-Responsive Interventions to Reduce Gender-Based Violence on College Campuses

Currently, the most successful prevention interventions against sexual violence (SV) on United States college campuses target modifications at the individual and interpersonal levels. Community-level interventions have been under-developed for college campuses. To address this gap, we employ a citizen science model for understanding campus community factors affecting SV risk. The model, called Our Voice, starts by engaging groups of college students to collect data in their own communities, identifying factors they view as increasing the risk of SV. In facilitated meetings, participants then review and analyze their collective data and use it to generate actionable community-level solutions and advocate for them with local decision-makers. We share findings from a first-generation study of the Our Voice model applied to SV prevention on one college campus, and include recommendations for further research.

Adolescent Levers for a Diet and Physical Activity Intervention Across Socioecological Levels in Kenya, South Africa, Cameroon, and Jamaica: Mixed Methods Study Protocol

Background

The increasing burden of noncommunicable diseases that are prevalent in low- and middle-income countries (LMICs) is largely attributed to modifiable behavioral risk factors such as unhealthy diets and insufficient physical activity (PA). The adolescent stage, defined as 10 to 24 years of age, is an important formative phase of life and offers an opportunity to reduce the risk of noncommunicable diseases across the life course and for future generations.

Objective

The aim of this paper is to describe a protocol for a study using a convergent mixed methods design to explore exposures in the household, neighborhood, school, and the journey from home to school that may influence diet and PA behaviors in adolescents from LMICs.

Methods

Male and female adolescents (n≥150) aged between 13 and 24 years will be recruited from selected high schools or households in project site countries to ensure the socioeconomic diversity of perspectives and experiences at the individual, home, and neighborhood levels. The project will be conducted at 5 sites in 4 countries: Kenya, Cameroon, Jamaica, and South Africa (Cape Town and Johannesburg). Data on anthropometric measures, food intake, and PA knowledge and behavior will be collected using self-report questionnaires. In addition, a small number of learners (n=30-45) from each site will be selected as citizen scientists to capture data (photographs, audio notes, text, and geolocations) on their lived experiences in relation to food and PA in their homes, the journey to and from school, and the school and neighborhood environments using a mobile app, and for objective PA measurements. In-depth interviews will be conducted with the citizen scientists and their caregivers to explore household experiences and determinants of food intake and foodways, as well as the PA of household members.

Results

The study described in this protocol paper was primarily funded through a UK National Institute for Health Research grant in 2017 and approved by the relevant institutional ethics review boards in the country sites (South Africa, Cameroun, and Jamaica in 2019, and Kenya in 2020). As of December 23, 2020, we had completed data collection from adolescents (n≥150) in all the country sites, except Kenya, and data collection for the subgroup (n=30-45) is ongoing. Data analysis is ongoing and the output of findings from the study described in this protocol is expected to be published by 2022.

Conclusions

This project protocol contributes to research that focuses on adolescents and the socioecological determinants of food intake and PA in LMIC settings. It includes innovative methodologies to interrogate and map the contexts of these determinants and will generate much-needed data to understand the multilevel system of factors that can be leveraged through upstream and downstream strategies and interventions to improve health outcomes.

Informatics-enabled citizen science to advance health equity

The COVID-19 pandemic has once again highlighted the ubiquity and persistence of health inequities along with our inability to respond to them in a timely and effective manner. There is an opportunity to address the limitations of our current approaches through new models of informatics-enabled research and clinical practice that shift the norm from small- to large-scale patient engagement. We propose augmenting our approach to address health inequities through informatics-enabled citizen science, challenging the types of questions being asked, prioritized, and acted upon. We envision this democratization of informatics that builds upon the inclusive tradition of community-based participatory research (CBPR) as a logical and transformative step toward improving individual, community, and population health in a way that deeply reflects the needs of historically marginalized populations.

Community-driven citizen science approach to explore cardiovascular disease risk perception, and develop prevention advocacy strategies in sub-Saharan Africa: a programme protocol

BACKGROUND

In sub-Saharan Africa (SSA), which experiences a disproportionately high cardiovascular disease (CVD) burden, population-based screening and prevention measures are hampered by low levels of knowledge about CVD and associated risk factors, and inaccurate perceptions of severity of risk.

METHODS

This protocol describes the planned processes for implementing community-driven participatory research, using a citizen science method to explore CVD risk perceptions and to develop community-specific advocacy and prevention strategies in the rural and urban SSA settings. Multi-disciplinary research teams in four selected African countries will engage with and train community members living in rural and urban communities as citizen scientists to facilitate conceptualization, co-designing of research, data gathering, and co-creation of knowledge that can lead to a shared agenda to support collaborative participation in community-engaged science. The emphasis is on robust community engagement, using mobile technology to support data gathering, participatory learning, and co-creation of knowledge and disease prevention advocacy.

DISCUSSION

Contextual processes applied and lessons learned in specific settings will support redefining or disassembling boundaries in participatory science to foster effective implementation of sustainable prevention intervention programmes in Low- and Middle-income countries.
