Equity implications for sanitation from recent health and nutrition evidence

Stories of change in nutrition in Burkina Faso 1992-2018: a micro-level perspective

Looking back at what has effectively improved nutrition may inform policy makers on how to accelerate progress to end all forms of malnutrition by 2030. As under-five stunting declined substantially in Burkina Faso, we analyzed its nutrition story at the micro-level. We conducted a regression-decomposition analysis to identify demographic and health drivers associated with change in height-for-age using longitudinal, secondary, nationally-representative data. We triangulated results with findings from semi-structured community interviews (n = 91) in two "model communities" with a history of large stunting reduction. We found that improvement in immunization coverage, assets accumulation and reduction in open defecation were associated with 23%, 10% and 6.1% of the improvement in height-for-age, respectively. Associations were also found with other education, family planning, health and WASH indicators. Model communities acknowledged progress in the coverage and quality of nutrition-specific and nutrition-sensitive sectoral programs co-located at the community level, especially those delivered through the health and food security sectors, though delivery challenges remained in a context of systemic poverty and persistent food insecurity. Burkina Faso's health sector's success in improving coverage of nutrition and healthcare programs may have contributed to improvements in child nutrition alongside other programmatic improvements in the food security, WASH and education sectors. Burkina Faso should continue to operationalize sectoral nutrition-sensitive policies into higher-quality programs at scale, building on its success stories such as vaccination. Community leverage gaps and data gaps need to be filled urgently to pressure for and monitor high coverage, quality delivery, and nutrition impact of agriculture, education, and WASH interventions.

Exploring barriers to the adoption and utilization of improved latrine facilities in rural Ethiopia: An Integrated Behavioral Model for Water, Sanitation and Hygiene (IBM-WASH) approach

BACKGROUND

Even though evidence shows that access to and use of improved latrines is related to healthful families and the public, obstacles to the adoption and use of improved latrine facilities remain. Globally, not many inquiries appear to have been carried out to satisfactorily inform us regarding the multi-level barriers influencing the adoption and utilization of improved latrines facilities. Related studies in Ethiopia are even fewer.

METHODS

Two qualitative data gathering methods, viz., key informant interviews and focus group discussions, were employed to collect data for this study. A total of fifteen focus group discussions were conducted with members of the community in the rural Wonago district of Ethiopia. Similarly, ten key informant interviews were conducted with water, sanitation, and hygiene officers, and health extension workers responsible for coordinating sanitation and hygiene activities. Open code software 4.03 was used for thematic analysis.

RESULT

Barriers to adoption and use of improved latrine facilities were categorized into Contextual factors (e.g. Gender, educational status, personal preference for using the field, limited space, population density, the status of land ownership), Psychosocial factors (Culture, beliefs, attitudes, and perceptions of minimal health threat from children's feces), and Technological factors (inconveniences in acquiring materials and cost of constructing a latrine).

CONCLUSION

There are a series of multi-leveled barriers to the sustained adoption and use of latrines. Providing funding opportunities for the underprivileged and offering training on the engineering skills of latrine construction at the community level based on the contextual soil circumstances could expand the latrine coverage and use. Similarly, taking into account the variability in motivations for adopting and using latrines among our study in Ethiopia and other studies, we implore public health experts to recognize behaviors and norms in their target communities in advance of implementing sanitation interventions.

When complexity matters: a step-by-step guide to incorporating a complexity perspective in guideline development for public health and health system interventions

BACKGROUND

Guidelines on public health and health system interventions often involve considerations beyond effectiveness and safety to account for the impact that these interventions have on the wider systems in which they are implemented. This paper describes how a complexity perspective may be adopted in guideline development to facilitate a more nuanced consideration of a range of factors pertinent to decisions regarding public health and health system interventions. These factors include acceptability and feasibility, and societal, economic, and equity and equality implications of interventions.

MAIN MESSAGE

A 5-step process describes how to incorporate a complexity perspective in guideline development with examples to illustrate each step. The steps include: (i) guideline scoping, (ii) formulating questions, (iii) retrieving and synthesising evidence, (iv) assessing the evidence, and (v) developing recommendations. Guideline scoping using stakeholder consultations, complexity features, evidence mapping, logic modelling, and explicit decision criteria is emphasised as a key step that informs all subsequent steps.

CONCLUSIONS

Through explicit consideration of a range of factors and enhanced understanding of the specific circumstances in which interventions work, a complexity perspective can yield guidelines with better informed recommendations and facilitate local adaptation and implementation. Further work will need to look into the methods of collecting and assessing different types of evidence beyond effectiveness and develop procedural guidance for prioritising across a range of decision criteria.

Achieving the Sustainable Development Goals for water and sanitation in Indonesia - Results from a five-year (2013-2017) large-scale effectiveness evaluation

Background

Access to safe sanitation and the elimination of open defecation are pre-conditions for improved child health and nutrition and wider achievement of the Sustainable Development Goals (SDGs). While Indonesia has a solid policy framework, the country ranks third globally in terms of numbers of people practicing open defecation.

Objectives

Our aim was to assess the effectiveness of a five-year strategy to reduce open defecation through accelerating implementation of the national sanitation program across districts receiving variable levels of external support.

Methods

Among three provinces with poor sanitation program performance, districts were selected to receive one of three levels of external support. High intensity districts (n = 6) benefitted from enabling environment strengthening support including political and social mobilization, direct capacity development, and efforts to strengthen planning, budgeting, monitoring and supervision; learning districts (n = 16) benefitted from cross-district learning opportunities and political mobilization through provincial government advocacy efforts; and comparison districts (n = 58) were monitored under routine program conditions. Outcomes included open defecation free (ODF) status and new toilet facility construction and were assessed through village level monitoring systems across all districts. Negative binomial regression and multivariate analysis were used to assess associations between levels of intervention intensity and outcomes.

Findings

Among districts receiving high-intensity external support improvements in political commitment, planning, coordination, financing, monitoring and supervision were observed. Relative to comparison districts, high intensity districts were more likely to be ODF (aRR 4.65, CI 2.12–10.20) with greater increase in household toilet coverage (aRR 11.15 CI 1.04–119.82). Weaker non-significant associations with ODF were observed among learning districts relative to comparison districts.

Interpretation

Efforts to strengthen provincial and district government capacity to implement sanitation programming in Indonesia can yield substantial improvements in outcomes in a relatively short period of time.

•

The effectiveness of five-year sanitation strategies in Indonesia was assessed.

•

In high-intensity districts improvements in government systems were observed.

•

High-intensity districts were more likely to be open defecation free.

•

Sanitation outcomes can be improved when government systems are strengthened.

Enabling Factors for Sustaining Open Defecation-Free Communities in Rural Indonesia: A Cross-Sectional Study

Community Approaches to Total Sanitation (CATS) programmes, like the Sanitasi Total Berbasis Masyarakat (STBM) programme of the Government of Indonesia, have played a significant role in reducing open defecation though still little is known about the sustainability of the outcomes. We assessed the sustainability of verified Open Defecation Free (ODF) villages and explored the association between slippage occurrence and the strength of social norms through a government conducted cross-sectional data collection in rural Indonesia. The study surveyed 587 households and held focus group discussions (FGDs) in six ODF villages two years after the government’s ODF verification. Overall, the slippage rate (i.e., a combination of sub-optimal use of a latrine and open defecation at respondent level) was estimated to be 14.5% (95% CI 11.6–17.3). Results of multivariate logistic regression analyses indicated that (1) weaker social norms, as measured by respondents’ perceptions around latrine ownership coverage in their community, (2) a lack of all-year round water access, and (3) wealth levels (i.e., not being in the richest quintile), were found to be significantly associated with slippage occurrence. These findings, together with qualitative analysis, concluded that CATS programmes, including a combination of demand creation, removal of perceived constraints through community support mechanisms, and continued encouragement to pursue higher levels of services with post-ODF follow-up, could stabilize social norms and help to sustain longer-term latrine usage in study communities. Further investigation and at a larger scale, would be important to strengthen these findings.
