Participatory science and innovation for improved sanitation and hygiene: process and outcome evaluation of project SHINE, a school-based intervention in Rural Tanzania

Making Germs Visible - Assessing the Impact of a School-Based, Low-Cost Intervention on Hand Hygiene Knowledge, Attitude and Practice of Children in Rural India

Handwashing with soap at critical moments is one of the most important factors in controlling the spread of germs and preventing the spread of infection. The objective of this study was to determine the effectiveness of a low-cost, school-based intervention that simulated germs and their spread on hand hygiene knowledge, attitude and practice of primary school children. Five hundred and sixty-two students from 28 rural schools were enrolled in this pre-posttest study. Endline data was collected 4 weeks after conducting the intervention at baseline. The mean scores for knowledge, attitude and practice improved significantly after the intervention (p < .05). Significant positive gains were also observed in children's understanding of germs, the associated illness threat and washing hands with soap as a prevention mechanism. The present study suggests that entertainment-education-based interventions have the potential to improve hygiene behavior among children while being low-cost.

BabyWASH and diarrhea prevention practices following multimedia educational intervention in hard-to-reach areas of the Afar and Somali regions of Ethiopia: a mixed-method endline evaluation

BACKGROUND

Water, sanitation, and hygiene (WASH) interventions, which are specifically targeted towards young children-known as "BabyWASH"-reduce exposure to environmental contamination and prevent microbial burden in their play and feeding environments. The purpose of this endline study was to evaluate the effectiveness and potential sustainability of a multimedia educational intervention in influencing key BabyWASH and diarrhea prevention practices in four hard-to-reach woredas (i.e. administrative districts) of the Afar and Somali regions of Ethiopia.

METHODS

A mixed-method, comparative cross-sectional study was conducted, which included 457 household surveys, 16 key informant interviews, and 8 focus group discussions. The multimedia educational intervention comprised: broadcasting radio talk shows and radio spot messages, capacity-building training for community health workers and community leaders, community mobilization campaigns, and the distribution of promotional print media materials. Propensity score matching analysis was used to estimate the effect of the multimedia educational intervention on key BabyWASH and diarrhea prevention attitudes and practices, which was then triangulated with qualitative findings.

RESULTS

The multimedia intervention had a significant positive impact on good BabyWASH and diarrhea prevention practices, including appropriate practices of child feces disposal (t-test = 5.17; p < 0.001), handwashing with soap or ash (t-test = 8.85; p < 0.001), maintaining separate playgrounds for young children (t-test = 2.83; p < 0.001), washing of child's body, hands, and faces (t-test = 15.78; p < 0.001), and food hygiene practices (t-test = 2.74; p < 0.05). The findings of the qualitative assessment also revealed that the multimedia intervention packages and the approaches used were successful in influencing key BabyWASH and diarrhea prevention behaviors in the intervention implementation woredas. In addition, providing capacity building training to local actors and community leaders and recording radio talk shows and sharing them with community members were recognized as effective intervention implementation strategies.

CONCLUSION

The endline evaluation found that the multimedia educational intervention improved awareness, perception, and practice of BabyWASH and diarrhea prevention behaviors in intervention woredas compared to control woredas. Sanitation and hygiene promotion interventions in pastoralist settings can be effective when using locally and contextually appropriate intervention strategies. However, considerations for integrating both behavioral and structural components in WASH interventions is essential.

Behavior Model of Community-Based Sanitation Management in Coastal Areas: Confirmatory Factor Analysis

Background

The research aims to analyze the factors consisting of resident status, gender role, stakeholder roles, infrastructure, socio-cultural, and socio-economic that influence the community behavior in managing the sanitation of coastal areas.

Methods

A cross-sectional design obtained 504,955 households of family heads in the Percut Sei Tuan Sub-district. The sample size was calculated using a category survey formula of 414 households. A simple random sampling technique was used, and the questionnaire instrument was tested for validity and reliability. The data were analyzed using CFA (Confirmatory Factor Analysis) to assess the factors that influence community behavior in managing sanitation.

Results

There was a socio-cultural relationship with the behavior of managing sanitation in coastal communities with a T-statistic value of 3.268. Furthermore, gender, infrastructure, and stakeholders' roles influence the behavior of managing sanitation with a T-statistic value of 3.310, 3.573, and 2.263, respectively.

Conclusions

Socio-cultural practices require motivation and support from various parties in creating good sanitation areas. Therefore, support from stakeholders is needed to influence the achievement of certain goals. They have the authority and budget that can be allocated to support efforts and improve sanitation.

Rural Entrepreneurship: An Analysis of Current and Emerging Issues from the Sustainable Livelihood Framework

Most entrepreneurship studies have an urban focus, and it is studied mainly from the perspective of opportunity exploitation. Rural entrepreneurship presents different characteristics, and it requires analysis from a resource-based view since this kind of entrepreneurial behavior takes place in rural communities under resource constraints. The sustainable livelihood perspective represents a relevant framework in rural entrepreneurship, considering resources and capacities to face poverty in rural areas. Therefore, this study presents a literature review to identify current and emerging issues in rural entrepreneurship from a sustainable livelihood framework. The literature review identifies that the main concepts involved in rural entrepreneurship and sustainable livelihood are women, poverty alleviation, youth, social entrepreneurship, and institutions. Likewise, social capital and human capital prevail as the most relevant capitals in the analyzed documents. The study offers research opportunities in emerging issues related to social entrepreneurship, governance and institutions, livelihood growth, and eco-entrepreneurship for extending the boundaries of rural entrepreneurship from the sustainable livelihood framework.

An Application of the Integrated Behavioral Model for Water, Sanitation and Hygiene to Assess Perceived Community Acceptability and Feasibility of the Biosand Filter among Maasai Pastoralists in Rural Tanzania

In addition to diarrheal disease risk, lack of access to safe water may have other indirect effects throughout one's life, such as school and workplace absenteeism, leading to less economic productivity. In contexts with scarce resources and unsafe drinking water, household water treatment and safe storage options such as the Biosand filter (BSF) allows households to directly reduce contamination and increase the quality of their drinking water. This study aimed to develop an understanding of perceived community acceptability and feasibility related to pre- and post-implementation of a BSF pilot project in rural Maasai households in the Ngorongoro Conservation Area (NCA), Tanzania. The study was guided by the Integrated Behavioral Model for Water Sanitation and Hygiene interventions (IBM-WASH) to understand the various factors influencing end-user perceptions of the BSF. In-depth interviews, group discussions and think tanks were conducted among a cross-section of community members, stakeholders, and other actors from May 2016 to September 2017. The data were analyzed using a thematic content analysis approach. A range of perceived contextual, technological, and psychosocial factors were found to potentially affect the acceptability and feasibility of BSF adoption in the NCA, highlighting the complex layers of influences in the setting. Whilst the BSF is seemingly an accepted option to treat water within the NCA, the community identified key barriers that may lower BSF adoption. The application of the IBM-WASH model served as a useful framework for evaluating the introduction of the BSF, identifying insights into contextual, technological, and psychosocial community factors.

Implementing trachoma control programmes in marginalised populations in Tanzania: A qualitative study exploring the experiences and perspectives of key stakeholders

Background

Despite aspects of the SAFE strategy for reducing trachoma in Tanzania have been somewhat successful, the disease still persists in marginalised communities even with repeated trachoma control interventions. This study aims to understand the facilitators and barriers associated with implementing trachoma control programmes in these communities, from the perspective of non-governmental organisations (NGOs).

Methods

Participants were the representatives of NGOs who had knowledge and experience in the implementation of trachoma control programmes. Data was collected using in-depth, semi-structured interviews guided by a topic guide, which was updated after each interview using a constant comparative method. Interviews were audio-recorded and then transcribed verbatim. Thematic analysis was done inductively. Codes were generated from the transcripts and then clustered into themes.

Findings

The context within marginalised communities often acted as a perceived barrier to successful implementation of control programmes. This included poor environmental cleanliness, lack of trust, poor disease knowledge and traditional lifestyles. Community values could either be a facilitator or a barrier, depending on the scenario. The anatomical location of the disease and the poor understanding of the disease progression also served as barriers. Considerations affecting decision-making among NGO’s include financial feasibility, community needs and whether the quality of the intervention could be improved. NGOs felt that the collaboration and the opportunity to learn from other organisations were beneficial aspects of having different actors. However, this also resulted in variability in the effectiveness of interventions between districts.

Conclusion

NGOs should focus on behaviour change and health education that is tailored to marginalised communities and seek innovative ways to implement trachoma intervention programmes whilst being minimally intrusive to the traditional way of life. Partners should also implement ways to ensure high quality programmes are being provided, by increasing staff accountability and compensating volunteers fairly.

Trachoma is a neglected tropical disease caused by the bacterium Chlamydia trachomatis and can result in blindness if left untreated. The World Health Organisation devised the SAFE strategy (Surgery, Antibiotics, Facial Cleanliness and Environmental Improvements) to combat this disease. In Tanzania, many trachoma control interventions are implemented by non-governmental organisations (NGOs). The disease still persists in areas with marginalised, including Maasai, despite repeated interventions. These communities are often difficult to reach due to their livelihoods and local beliefs. This study investigates the facilitators and barriers to implementing interventions within hard to reach communities from the perspectives of NGOs. Findings will provide insight on how NGOs implement and ensure their programmes are effective, whilst being mindful of the intrinsic factors important to the community, which will inform improvements and alterations in trachoma interventions.

Attributes of drinking water, sanitation, and hygiene associated with microbiological water quality of stored drinking water in rural schools in Mozambique and Uganda

Contaminated drinking water causes morbidity and mortality worldwide, especially in low- and middle-income countries. Drinking water quality has been studied extensively in household settings, but little research is available on drinking water quality in schools. School settings are of particular importance, because children are more susceptible than adults to a variety of diseases from contaminated drinking water. Many school water, sanitation and hygiene (WaSH) interventions have been studied for their efficacy to reduce diarrheal disease incidence, but few have evaluated drinking water quality, which reflects an important exposure pathway between WaSH services and health outcomes. Using school surveys developed from internationally established WaSH indicators and field microbiological water quality tests, we studied 374 rural schools in Mozambique and Uganda to understand the association between specific WaSH services and drinking water microbiological contamination, specifically testing most probable number (MPN) of Escherichia coli, an indicator of fecal contamination, per 100 mL. In Mozambique and Uganda, 71% and 83% respectively of rural schools had low risk drinking water quality (<1 E. coli/100 mL); thirteen percent and seven percent had very high-risk water quality (≥100 E. coli/100 mL). When accounting for all WaSH services studied, schools that used an improved-type water source had 0.22 times less E. coli in stored drinking water in Mozambique (95% CI: 0.07, 0.65) and 0.12 times less E. coli in Uganda (95% CI: 0.02, 0.80). In Mozambique, use of a water source within 30 minutes for travel and collection and the presence of water and soap/ash for handwashing were also significantly associated with less E. coli in drinking water. The findings of this study provide public health practitioners with implementable WaSH services to improve school drinking water quality, which has implications for the health, learning environment, and cognitive development of school children in rural Mozambique and Uganda.

Evaluating children's handwashing in schools: an integrative review of indicative measures and measurement tools

Children are a key target of handwashing interventions as washing hands reduces the spread of disease and reliance on antibiotics. While there is guidance for evaluating handwashing with adults in other settings, this is lacking for children in schools. An integrative review of 65 studies where handwashing was measured in schools was conducted to establish which indicative measures (what is measured to evaluate the processes and/or impacts of, handwashing) and measurement tools (data collection instruments) have been applied to evaluate handwashing in schools, and under what circumstances. Further analysis highlighted different challenges when seeking to apply such measures and tools in schools, as opposed to other settings. It was concluded that indicative measures, and measurement tools need to be appropriate to the organizational setting, the study participants, and research objectives. A summative analysis of relevant considerations is presented.

Participatory Epidemiology: Principles, Practice, Utility, and Lessons Learnt

Participatory epidemiology (PE) evolved as a branch of veterinary epidemiology and has been largely employed for the control and early warning of infectious diseases within resource-limited settings. It was originally based on combining practitioner communication skills with participatory methods to facilitate the involvement of animal caretakers and owners (embracing their knowledge, experience, and motivations) in the identification and assessment of animal disease problems, including in the design, implementation, monitoring and evaluation of disease control programs, policies, and strategies. With the importance of understanding social perceptions and drivers receiving increasing recognition by epidemiologists, PE tools are being adapted for an increasingly wide range of settings and endeavors. More recently, PE tools have been adapted for use in food and nutrition security programs, One Health activities, wildlife disease surveillance and as part of mixed-methods research across a range of socio-economic settings. This review describes the evolution of PE (in relation to veterinary epidemiology and briefly in relation to public health epidemiology), the underpinning philosophy and principles essential to its effective application and the importance of gender-sensitive approaches and data triangulation, including conventional confirmatory testing. The article also provides illustrative examples highlighting the diversity of approaches and applications of PE, hallmarks of successful PE initiatives and the lessons we can learn when these are missing. Finally, we look forward, describing the particular utility of PE for dealing with emerging infectious diseases, gaining attention of field-level cross-sector officials who can escalate concerns to a higher level and for continuing to raise the voices of those less-heard (such as women, minority groups, and remote communities with limited exposure to formal education) in defining the problems and planning activities that will likely impact directly on their well-being and livelihoods.

Health interventions among mobile pastoralists: a systematic review to guide health service design

OBJECTIVE

Mobile pastoralists are one of the last populations to be reached by health services and are frequently missed by health campaigns. Since health interventions among pastoralists have been staged across a range of disciplines but have not yet been systematically characterised, we set out to fill this gap.

METHODS

We conducted a systematic search in PubMed/MEDLINE, Scopus, Embase, CINAL, Web of Science, WHO Catalog, AGRICOLA, CABI, ScIELO, Google Scholar and grey literature repositories to identify records that described health interventions, facilitators and barriers to intervention success, and factors influencing healthcare utilisation among mobile pastoralists. No date restrictions were applied. Due to the heterogeneity of reports captured in this review, data were primarily synthesised through narrative analysis. Descriptive statistical analysis was performed for data elements presented by a majority of records.

RESULTS

Our search yielded 4884 non-duplicate records, of which 140 eligible reports were included in analysis. 89.3% of reports presented data from sub-Saharan Africa, predominantly in East Africa (e.g. Ethiopia, 30.0%; Kenya, 17.1%). Only 24.3% of reports described an interventional study, while the remaining 75.7% described secondary data of interest on healthcare utilisation. Only two randomised controlled trials were present in our analysis, and only five reports presented data on cost. The most common facilitators of intervention success were cultural sensitivity (n = 16), community engagement (n = 12) and service mobility (n = 11).

CONCLUSION

Without adaptations to account for mobile pastoralists' unique subsistence patterns and cultural context, formal health services leave pastoralists behind. Research gaps, including neglect of certain geographic regions, lack of both interventional studies and diversity of study design, and limited data on economic feasibility of interventions must be addressed to inform the design of health services capable of reaching mobile pastoralists. Pastoralist-specific delivery strategies, such as combinations of mobile and 'temporary fixed' services informed by transhumance patterns, culturally acceptable waiting homes, community-directed interventions and combined joint human-animal One Health design as well as the bundling of other health services, have shown initial promise upon which future work should build.

Water Scarcity and Water Quality: Identifying Potential Unintended Harms and Mitigation Strategies in the Implementation of the Biosand Filter in Rural Tanzania

Bottom-up public health interventions are needed which are built on an understanding of community perspectives. Project SHINE is a community-based participatory action research intervention focused on developing sustainable water, sanitation, and hygiene strategies with Maasai pastoralists in Tanzania. The aim of the study is to understand perceptions related to water quality and scarcity as well as to assess the potential of the Biosand Filter as a low-cost, low-tech water treatment option. To avoid unintended harms, the community was engaged in identifying potential harms and mitigation strategies prior to the implementation of the filter.Two in-depth interviews and two group discussions were analyzed using thematic content analysis, while three think tanks were analyzed using directed content analysis. The findings highlight a range of concerns regarding water scarcity and quality. The think tank approach was an effective means of engaging the community in identifying potential unintended harms across four dimensions: the physical, psychosocial, economic, and cultural contexts. In addition, two external themes emerged as salient: political harm and harm by omission.

System Approaches to Water, Sanitation, and Hygiene: A Systematic Literature Review

Endemic issues of sustainability in the water, sanitation, and hygiene (WASH) sector have led to the rapid expansion of ‘system approaches’ for assessing the multitude of interconnected factors that affect WASH outcomes. However, the sector lacks a systematic analysis and characterization of the knowledge base for systems approaches, in particular how and where they are being implemented and what outcomes have resulted from their application. To address this need, we conducted a wide-ranging systematic literature review of systems approaches for WASH across peer-reviewed, grey, and organizational literature. Our results show a myriad of methods, scopes, and applications within the sector, but an inadequate level of information in the literature to evaluate the utility and efficacy of systems approaches for improving WASH service sustainability. Based on this analysis, we propose four recommendations for improving the evidence base including: diversifying methods that explicitly evaluate interconnections between factors within WASH systems; expanding geopolitical applications; improving reporting on resources required to implement given approaches; and enhancing documentation of effects of systems approaches on WASH services. Overall, these findings provide a robust survey of the existing landscape of systems approaches for WASH and propose a path for future research in this emerging field.

Theory-driven formative research to inform the design of a national sanitation campaign in Tanzania

Introduction

There are gaps in global understanding about how to design and implement interventions to improve sanitation. This formative study provided insights for the subsequent redesign of a government-led national sanitation campaign targeting rural populations in Tanzania.

Methods

The Behaviour Centred Design approach was used to investigate the determinants of toilet building, improvement and use. Varied, novel, and interactive research tools were employed in fifty-five households in two regions of rural Tanzania. Results were analysed to articulate a Theory of Change, which then informed intervention design.

Results

Participants valued hard work, enterprise, and improving their lives over many years. They wanted better toilets but felt no urgency to act quickly. A common emotional motivator for improving toilets was to protect children from disease (Nurture) but this was insufficient to drive rapid change. Disgust with traditional toilets meant they were built at a distance from the house: an ‘out of sight, out of mind’ attitude. Other powerful motives included the desire to improve living conditions (Create), and to become a modern Tanzanian (Status), albeit without ‘showing off’. Construction costs and water scarcity were the main stated barriers. Receiving information about realistic costs, support accessing materials, and visiting better latrines elsewhere were commonly reported reasons for improving latrines.

Conclusions

The resulting Theory of Change recommended that the intervention should surprise people with a novel conversation about toilets, promote toilets as a means of conferring status, and introduce a perceived urgency to ‘act now’. It should suggest that modest improvements would lead to a better life. Feelings of disgust and fear with poor quality toilets should be amplified, and barriers lessened through promoting transformational toilet improvements, and improving access to modern toilet products. This research provided considerable insight into sanitation behaviours in rural Tanzania, which informed creative intervention design.

Water, Sanitation and Hygiene (WASH) in Schools in Low-Income Countries: A Review of Evidence of Impact

Many schools in low-income countries have inadequate access to water facilities, sanitation and hygiene promotion. A systematic review of literature was carried out that aimed to identify and analyse the impact of water, sanitation and hygiene interventions (WASH) in schools in low-income countries. Published peer reviewed literature was systematically screened during March to June 2018 using the databases PubMed, Embase, Web of Science, the Cochrane Library, Science Direct, and Google Scholar. There were no publication date restrictions. Thirty-eight peer reviewed papers were identified that met the inclusion criteria. The papers were analysed in groups, based on four categories of reported outcomes: (i) reduction of diarrhoeal disease and other hygiene-related diseases in school students; (ii) improved WASH knowledge, attitudes and hygiene behaviours among students; (iii) reduced disease burden and improved hygiene behaviours in students’ households and communities; (iv) improved student enrolment and attendance. The typically unmeasured and unreported ‘output’ and/or ‘exposure’ of program fidelity and adherence was also examined. Several studies provide evidence of positive disease-related outcomes among students, yet other assessments did not find statistically significant differences in health or indicated that outcomes are dependent on the nature and context of interventions. Thirteen studies provide evidence of changes in WASH knowledge, attitudes and behaviours, such as hand-washing with soap. Further research is required to understand whether and how school-based WASH interventions might improve hygiene habits and health among wider family and community members. Evidence of the impact of school-based WASH programs in reducing student absence from school was mixed. Ensuring access to safe and sufficient water and sanitation and hygiene promotion in schools has great potential to improve health and education and to contribute to inclusion and equity, yet delivering school-based WASH intervention does not guarantee good outcomes. While further rigorous research will be of value, political will and effective interventions with high program fidelity are also key.
