Impact of a demand-side integrated WASH and nutrition community-based care group intervention on behavioural change: a randomised controlled trial in western Kenya

Assessment of water, hygiene, and sanitation practice and associated factors among Bihari refugee camp in Bangladesh: A cross-sectional study

Background and Aims

The global significance of water, sanitation, and hygiene (WASH) cannot be overstated, extending far beyond the confines of developing nations and encompassing even the most developed ones. This study, rooted in the Bihari refugee camp in Bangladesh, seeks to underscore the universality of WASH concerns.

Methods

Using a cross-sectional design and a structured questionnaire, we conducted a meticulous evaluation of WASH practices with 313 participants selected through random sampling.

Results

Findings shows the water practice, among all of them, only 4.8% of the respondents were very happy with the water supply system and 16.0% of the respondents were happy with this. A total of 29.7% of the respondents were satisfied with safe drinking water and only 4.8% of the respondents were very satisfied with safe drinking water. Regarding the hygiene practice, among all respondents, 10.2% of them were satisfied with using the same bathroom by multiple people. Only 5.4% respondents were happy in their living environment. Regarding sanitation practice, only 31.3% had private toilet facilities. Among all of the respondents, 13.7% of the respondents were satisfied with using the same toilet by multiple people. Respondents who were illiterate (p < 0.01) and self-employed (p < 0.04) were satisfied with the water supply. Similarly, respondents who were illiterate (p < 0.03) and self-employed (p < 0.00) were satisfied with safe drinking water. Respondents who were illiterate (p < 0.02) and whose monthly income was below 8000 BDT (p < 0.00) were satisfied using same bathroom by multiple people. Respondents who were self-employed (p < 0.01), whose monthly income 8000-12,000 BDT (p < 0.01) and having single room (p < 0.00) were satisfied using the same toilet by multiple people.

Conclusion

Enhanced access to safe WASH facilities, coupled with a comprehensive understanding of the study's findings, have the potential to serve as vital signposts for the development and implementation of policies and interventions.

Evidence-based complementary feeding recipe book for Kenyan caregivers: A novel approach

The Kenyan Ministry of Health (MOH) and a consortium of nutritionists, researchers and communication, and design specialists developed a novel approach to create an evidence-based recipe book promoting complementary feeding (CF) in Kenya. The ADAPT approach includes five steps: applied research (A), dialogue with stakeholders (D), adapted behaviour change communication (BCC) theories (A), purpose-driven visual communication (P), and tailoring to priority audiences (T). Through this approach, the recipe book addresses key knowledge gaps using behaviour change theories and visual communication best practice to increase accessibility, acceptability, retention and motivation for behaviour change. The book addresses barriers to CF identified through formative applied research. Dialogue with stakeholders helped ensure cultural appropriateness and the book's alignment with MOH recommendations and key messages. The book uses behaviour change theories to approach the reader in a respectful way that motivates behaviour change. The use of consistent, purpose-driven visuals helps ensure key messages are easily understood and accessible to all caregivers regardless of literacy level. The book's tone and content are tailored to its audiences' attributes, needs and preferences. This five-step process inspired the development of ADAPT, a novel approach that integrates behaviour change and visual communication for greater impact. This paper outlines how the consortium used the ADAPT approach to develop an evidence-based book that thoughtfully and holistically addresses a wide range of barriers, provides practical solutions and increases self-efficacy around CF. It offers a blueprint for public health practitioners from any field who are interested in using visual behaviour change communication to promote healthy behaviour.

Influence of care group participation on infant and young child feeding, dietary diversity, WASH behaviours and nutrition outcomes in rural Zimbabwe

Background

The care group approach (CGA) is a community-based nutrition behaviour change strategy centred on 'peer-to-peer learning' through women support groups.

Objective

To assess the impact of the CGA on the adoption of appropriate infant and young child feeding (IYCF), dietary diversity and water, sanitation and hygiene (WASH) practices, and associated nutrition-related outcomes.

Methods

A retrospective cohort study used a mixed-method approach in selected rural districts in Zimbabwe in June 2022. A structured questionnaire was used to collect data on IYCF, diet quality, WASH and child morbidity. Binary logistic regression was used to evaluate the association between exposure and outcome. Significance was at p<0.05.

Results

A total of 127 exposed and 234 controls were enrolled. There was no significant difference between exposed and controls on the prevalence of; diarrhoea (p=0.659), cough (p=0.191) and fever (p=0.916). No significant difference was observed in the proportion ever breastfed (p=0.609), Children with Adequate Dietary Diversity Score (p=0.606) across the two groups. However, the proportion of families with adequate Household Dietary Diversity Score (HDDS) (p=0.005) and Minimum Dietary Diversity for Women (MDD-W) (p=0.009) were significantly higher in exposed than controls. Knowledge on all promoted behaviours was significantly higher in the exposed than in controls with the exception of exclusive breast feeding. While the practices were significantly higher in exposed compared with controls for: 'Appropriate complementary feeding for children aged 6-24 months' (p=0.001), 'good nutrition for women of reproductive age' (p=0.001), 'production and consumption of diverse nutritious food' (p=0.001) and 'production and consumption of biofortified crops' (p=0.001).

Conclusions

The results showed that CGA potential to increase knowledge and achieve nutrition and health-related behaviour change in low-income settings if integrated into existing community programmes. Interestingly, HDDS and MDD-W were significantly higher in exposed than controls. However, more research is required to obtain conclusive results.

Prevention of human exposure to livestock faecal waste in the household: a scoping study of interventions conducted in sub-Saharan Africa

BACKGROUND

Poorly managed animal faecal waste can result in detrimental environmental and public health implications. Limiting human exposure to animal waste through Animal inclusive Water Sanitation and Hygiene (A-WASH) strategies is imperative to improve public health in livestock keeping households but has received little attention to date. A small number of A-WASH interventions have previously been identified through a systematic review by another research team, and published in 2017. To inform intervention design with the most up-to-date information, a scoping study was conducted to map the existing evidence for A-WASH in sub-Saharan Africa (SSA) emerging since the previous review.

METHODS

This review followed PRISMA guidelines to identify interventions in SSA published between January 2016 to October 2022. Databases searched included PubMed, PMC Europe, CabDirect and Web of Science. Studies were eligible for inclusion if they were written in English and documented interventions limiting human contact with animal faecal material in the SSA context. Key data extracted included: the intervention itself, its target population, cost, measure of effectiveness, quantification of effect, assessment of success, acceptability and limitations. These data were synthesized into a narrative, structured around the intervention type.

FINDINGS

Eight eligible articles were identified. Interventions to reduce human exposure to animal faecal matter were conducted in combination with 'standard' human-centric WASH practices. Identified interventions included the management of human-animal co-habitation, educational programs and the creation of child-safe spaces. No novel A-WASH interventions were identified in this review, beyond those identified by the review in 2017. Randomised Controlled Trials (RCTs) were used to evaluate six of the eight identified interventions, but as effect was evaluated through various measures, the ability to formally compare efficacy of interventions is lacking.

CONCLUSION

This study indicates that the number of A-WASH studies in SSA is increasing and the use of RCTs suggests a strong desire to create high-quality evidence within this field. There is a need for standardisation of effect measures to enable meta-analyses to be conducted to better understand intervention effectiveness. Evaluation of scalability and sustainability of interventions is still lacking in A - WASH research.

Safe infant feeding in healthcare facilities: Assessment of infection prevention and control conditions and behaviors in India, Malawi, and Tanzania

Infants need to receive care in environments that limit their exposure to pathogens. Inadequate water, sanitation, and hygiene (WASH) environments and suboptimal infection prevention and control practices in healthcare settings contribute to the burden of healthcare-associated infections, which are particularly high in low-income settings. Specific research is needed to understand infant feeding preparation in healthcare settings, a task involving multiple behaviors that can introduce pathogens and negatively impact health. To understand feeding preparation practices and potential risks, and to inform strategies for improvement, we assessed facility WASH environments and observed infant feeding preparation practices across 12 facilities in India, Malawi, and Tanzania serving newborn infants. Research was embedded within the Low Birthweight Infant Feeding Exploration (LIFE) observational cohort study, which documented feeding practices and growth patterns to inform feeding interventions. We assessed WASH-related environments and feeding policies of all 12 facilities involved in the LIFE study. Additionally, we used a guidance-informed tool to carry out 27 feeding preparation observations across 9 facilities, enabling assessment of 270 total behaviors. All facilities had 'improved' water and sanitation services. Only 50% had written procedures for preparing expressed breastmilk; 50% had written procedures for cleaning, drying, and storage of infant feeding implements; and 33% had written procedures for preparing infant formula. Among 270 behaviors assessed across the 27 feeding preparation observations, 46 (17.0%) practices were carried out sub-optimally, including preparers not handwashing prior to preparation, and cleaning, drying, and storing of feeding implements in ways that do not effectively prevent contamination. While further research is needed to improve assessment tools and to identify specific microbial risks of the suboptimal behaviors identified, the evidence generated is sufficient to justify investment in developing guidance and programing to strengthen infant feeding preparation practices to ensure optimal newborn health.

Patients' views on health promotion and disease prevention services provided by healthcare workers in a South African tertiary hospital

BACKGROUND

Patients' views and experiences in healthcare institutions provide a means of assessing the quality of services patients receive from healthcare workers (HCWs). However, the views of patients on the health promotion (HP) and disease prevention (DP) services offered by HCWs and the delivery mode have not been adequately studied.

AIM

This study assessed the views of patients on HP and DP services provided by various categories of HCWs.

SETTING

The study was conducted at a tertiary hospital in the Nelson Mandela Bay Municipality, South Africa.

METHOD

An exploratory cross-sectional study was conducted among 500 patients. The questionnaire elicited responses from patients regarding the HP and DP services received from the different cadres of HCWs at three different admission phases: pre-admission phase (PAP), admission phase (ADP), and post-admission phase (POP). Descriptive, bivariate, and multivariate analysis was conducted.

RESULTS

In the PAP, most patients (83.33%, n = 5; 87.85%, n = 217; and 76.14%, n = 150) seen by the rehabilitation health workers, medical doctors, and nurses respectively were empowered to manage their health. Patients attended to by nurses were 0.45 (95% CI 0.27-0.74) times less likely than those attended to by medical doctors to receive information that that will help them address the physical and environmental needs. In the ADP, patients attended to by nurses were less likely, compared to those attended to by medical doctors to be empowered to have good control over their health. In the POP, patients attended to by nurses are more likely to have their health behaviours change for better compared to those not seen by any HCW.

CONCLUSION

Patients attending tertiary hospital received greater HP and DP services during the PAP and ADP of patient care. Greatest influence for behavioural change of patients on HP and DP were achieved from the medical doctors, nurses and rehabilitation service staff. Improving structural factors may prove beneficial in enhancing patients' experience from all HCW groups and phases of patient care.

Determinants of food preparation and hygiene practices among caregivers of children under two in Western Kenya: a formative research study

INTRODUCTION

Diarrhea is a leading cause of child morbidity and mortality worldwide and is linked to early childhood stunting. Food contamination from improper preparation and hygiene practices is an important transmission pathway for exposure to enteric pathogens. Understanding the barriers and facilitators to hygienic food preparation can inform interventions to improve food hygiene. We explored food preparation and hygiene determinants including food-related handwashing habits, meal preparation, cooking practices, and food storage among caregivers of children under age two in Western Kenya.

METHODS

We used the Capabilities, Opportunities, and Motivations model for Behavior Change (COM-B) framework in tool development and analysis. We conducted 24 focus group discussions with mothers (N = 12), fathers (N = 6), and grandmothers (N = 6); 29 key informant interviews with community stakeholders including implementing partners and religious and community leaders; and 24 household observations. We mapped the qualitative and observational data onto the COM-B framework to understand caregivers' facilitators and barriers to food preparation and hygiene practices.

RESULTS

Facilitators and barriers to food hygiene and preparation practices were found across the COM-B domains. Caregivers had the capability to wash their hands at critical times; wash, cook, and cover food; and clean and dry utensils. Barriers to food hygiene and preparation practices included lack of psychological capability, for instance, caregivers' lack of knowledge of critical times for handwashing, lack of perceived importance of washing some foods before eating, and not knowing the risks of storing food for more than four hours without refrigerating and reheating. Other barriers were opportunity-related, including lack of resources (soap, water, firewood) and an enabling environment (monetary decision-making power, social support). Competing priorities, socio-cultural norms, religion, and time constraints due to work hindered the practice of optimal food hygiene and preparation behaviors.

CONCLUSION

Food hygiene is an underexplored, but potentially critical, behavior to mitigate fecal pathogen exposure for young children. Our study revealed several knowledge and opportunity barriers that could be integrated into interventions to enhance food hygiene.

Sustainable Elimination of Schistosomiasis in Ethiopia-A Five-Year Follow-Up Study

In 2009, Mekele, the capital of the Tigray Region in Ethiopia, presented a mean prevalence of 44.7% of schistosomiasis (S. mansoni) in school children. Termed a public health problem, NALA, an international public health non-governmental organization, and their partners implemented a novel model of intervention, which aimed to compliment mass drug administration (MDA) campaigns with behavioral change (BC) and improved sanitation to achieve sustained elimination of schistosomiasis. The four-year intervention (2009−2012) covered 38 primary schools. The objective of this study was to examine factors associated with control or resurgence of the disease, and the association between the behavioral change program and disease prevalence, ten years after initiation. Eleven primary schools were selected for this follow-up study. All students provided a stool sample and filled in a knowledge, attitude and practice (KAP) questionnaire. In seven out of eleven schools (63.6%) the prevalence of schistosomiasis was maintained below 2% ten years after the initiation of the intervention. In four schools, prevalence returned to pre-intervention levels, defining them as persistent hot spots (PHS). Students from PHS schools scored lower on KAP questionnaires compared to students from responder schools; 3.9 ± 0.9 vs. 4.2 ± 0.9 (p-value < 0.001) for practice questions and 4.4 ± 1.4 vs. 4.6 ± 1.5 (p-value = 0.03) for attitude questions. The prevalence of schistosomiasis correlated positively with age, (p-value = 0.049), sex (relative risk = 1.7, p-value < 0.001), and location. Semi-urban locations (n = 382) had higher disease prevalence than urban locations (n = 242), (22.7% vs. 5.5%, p-value < 0.001). Students residing in semi-urban areas and close to a river (<500 m) were at higher risk of contracting schistosomiasis than those living in urban areas far from the river (RR = 5.95, p-value < 0.001). Finally, a correlation between prevalence and proximity of schools to rivers was found (semi-urban areas; RR = −0.91, p-value = 0.001 vs. urban areas; RR = −0.51, p-value = 0.001). Soil-transmitted-helminths prevalence in 2009 was 8.1% and declined during the intervention years to 0.5%. Prevalence in 2018 was found to be stable at 0.8%. These results demonstrate the long-term success of NALAs’ comprehensive model of intervention for elimination of schistosomiasis in school children, combining behavioral change and improved sanitation with MDA.

Application of the Capabilities, Opportunities, Motivations, and Behavior (COM-B) Change Model to Formative Research for Child Nutrition in Western Kenya

Background

Interventions aimed at improving dietary intake and feeding practices have alone proven insufficient for combatting stunting resulting from poor nutrition and repeated infections.

Objectives

To support the development of an integrated water, sanitation, and hygiene (WASH) and nutrition, social, and behavior change strategy aimed at reducing stunting, formative research was conducted in 2 program sites in western Kenya.

Methods

Twenty-nine key informant interviews were conducted with community leaders, health workers, and project staff, and 24 focus group discussions with caregivers of children under 2 y on topics related to feeding, sanitation, and hygiene behaviors. Three frameworks informed the study design and analysis of our formative research: the Capabilities, Opportunities, and Motivations model for behavior change, which identifies what needs to change in order for behavior change interventions to be effective; the Grandmother Project's Change Through Culture Approach, which values the important role of influential household and community members in producing household health; and Starr and Fornoff's approach to Theory of Change development.

Results

Caregivers exhibited sufficient psychological capabilities (knowledge and skills) for many of the key maternal and infant nutrition behaviors. However, reflective motivation to perform optimal behaviors was undermined by limitations in physical and social opportunities, including limited time and competing priorities for mothers, limited accessibility and availability of diverse foods, low self-efficacy for exclusive breastfeeding, and fears of negative consequences related to specific foods and recommended practices.

Conclusions

Interventions that aim to improve maternal and child diets should address the underlying social, cultural, and environmental determinants that contribute to motivations and opportunities to perform recommended practices.

Evaluations of water, sanitation and hygiene interventions should not use diarrhoea as (primary) outcome

Water, sanitation and hygiene interventions have been the subject of cluster trials of unprecedented size, scale and cost in recent years. However, the question 'what works in water, sanitation, hygiene (WASH)?' remains poorly understood. Evaluations of community interventions to prevent infectious disease typically use lab-confirmed infection as a primary outcome; however, WASH trials mostly use reported diarrhoea. While diarrhoea is a significant source of morbidity, it is subjected to significant misclassification error with respect to enteric infection due to the existence of non-infectious diarrhoea and asymptomatic infection. We show how this may lead to bias of estimated effects of interventions from WASH trials towards no effect. The problem is further compounded by other biases in the measurement process. Alongside testing for infection of the gut, an examination of the causal assumptions underlying WASH interventions present several other reliable alternative and complementary measurements and outcomes. Contemporary guidance on the evaluation of complex interventions requires researchers to take a broad view of the causal effects of an intervention across a system. Reported diarrhoea can fail to even be a reliable measure of changes to gastrointestinal health and so should not be used as a primary outcome if we are to progress our knowledge of what works in WASH.

Benefits and Risks of Smallholder Livestock Production on Child Nutrition in Low- and Middle-Income Countries

Livestock production may improve nutritional outcomes of pregnant women and children by increasing household income, availability of nutrient-dense foods, and women's empowerment. Nevertheless, the relationship is complex, and the nutritional status of children may be impaired by presence of or proximity to livestock and their pathogens. In this paper, we review the benefits and risks of livestock production on child nutrition. Evidence supports the nutritional benefits of livestock farming through income, production, and women's empowerment. Increasing animal source food consumption requires a combination of efforts, including improved animal management so that herd size is adequate to meet household income needs and consumption and addressing sociocultural and gendered norms. Evidence supports the inclusion of behavior change communication strategies into livestock production interventions to facilitate the sustainability of nutritional benefits over time, particularly interventions that engage women and foster dimensions of women's empowerment. In evaluating the risks of livestock production, evidence indicates that a broad range of enteric pathogens may chronically infect the intestines of children and, in combination with dietary deficits, may cause environmental enteric dysfunction (EED), a chronic inflammation of the gut. Some of the most important pathogens associated with EED are zoonotic in nature with livestock as their main reservoir. Very few studies have aimed to understand which livestock species contribute most to colonization with these pathogens, or how to reduce transmission. Control at the point of exposure has been investigated in a few studies, but much less effort has been spent on improving animal husbandry practices, which may have additional benefits. There is an urgent need for dedicated and long-term research to understand which livestock species contribute most to exposure of young children to zoonotic enteric pathogens, to test the potential of a wide range of intervention methods, to assess their effectiveness in randomized trials, and to assure their broad adaptation and sustainability. This review highlights the benefits and risks of livestock production on child nutrition. In addition to identifying research gaps, findings support inclusion of poor gut health as an immediate determinant of child undernutrition, expanding the established UNICEF framework which includes only inadequate diet and disease.

The Applications of Implementation Science in Water, Sanitation, and Hygiene (WASH) Research and Practice

BACKGROUND

Delivery of high quality, at-scale, and sustained services is a major challenge in the water, sanitation, and hygiene (WASH) sector, made more challenging by a dearth of evidence-based models for adaption across contexts in low- and middle-income countries.

OBJECTIVE

We aim to describe the value of implementation science (IS) for the WASH sector and provide recommendations for its application.

METHODS

We review concepts from the growing field of IS-defined as the "scientific study of methods to promote the systematic uptake of research findings and other evidence-based practices into routine practice, and hence, to improve the quality and effectiveness of health services"-and we translate their relevance to WASH research, learning, and delivery.

DISCUSSION

IS provides a suite of methods and theories to systematically develop, evaluate, and scale evidence-based interventions. Though IS thinking has been applied most notably in health services delivery in high-income countries, there have been applications in low-income settings in fields such as HIV/AIDS and nutrition. Expanding the application of IS to environmental health, specifically WASH interventions, would respond to the complexity of sustainable service delivery. WASH researchers may want to consider applying IS guidelines to their work, including adapting pragmatic research models, using established IS frameworks, and cocreating knowledge with local stakeholders. https://doi.org/10.1289/EHP7762.
