Understanding Households' Willingness to Pay for Improved Sanitation Services in Benin: A Study Protocol.

Nowadays, in Benin, latrine construction by households highly depends on their financial contributions. However, empirical evidence shows that many households are unwilling to invest in adequate sanitation services. The study aims to determine the household's willingness to pay for improved sanitation services and the associated factors. The study population will include households lacking unimproved sanitation facilities. The household heads will be eligible for survey participation. We will perform a contingent valuation to determine households' willingness to pay for a Ventilated Improved Pit (VIP) latrine. Following a description of the surveyed population, we will assess willingness to pay using the 'doubleb' command in Stata. Subsequently, we will conduct multivariate logistic regression to determine the factors associated with willingness to pay. The expected results will be: a description of the basic characteristics of households without improved sanitation services, an estimation of household willingness to pay for VIP latrines using the contingent valuation, and factors associated with household willingness to pay for VIP latrines. This study will contribute to the literature on household demand for improved sanitation services in Benin.

Exploring the association between household access to water, sanitation and hygiene (WASH) services and common childhood diseases using data from the 2017-2018 Demographic and Health Survey in Benin: focus on diarrhoea and acute respiratory infection.

OBJECTIVE: The paper aimed to study the association between household access to water, sanitation and hygiene (WASH) services and the occurrence of diarrhoea and acute respiratory infection among children under 5 years in Benin. DESIGN: We performed secondary analyses using Benin's Fifth Demographic and Health Survey datasets. The dependent variables were diarrhoea and acute respiratory infection (yes=1, no=0). Among the independent variables were the household access to individual WASH services, grouped as follows: 'basic', 'limited', 'unimproved' and 'no service'. Multivariate logistic regression was used to determine the association between household access to WASH services and the occurrence of diarrhoea and acute respiratory infection. Results from the multivariate logistic regression were presented using adjusted Odds Ratios (aORs) with 95% Confidence Intervals (95% CIs). SETTING: Benin. PARTICIPANTS: Children under 5 years successfully surveyed during Benin's Fifth Demographic and Health Survey. OUTCOME MEASURES: Diarrhoea and acute respiratory infection. RESULTS: In the current study, 12 034 children under 5 years met the selection criteria and were included in the analyses. The prevalence of diarrhoea and acute respiratory infection was 10.5% (95% CI=9.8% to 11.3%) and 2.9% (95% CI=2.5% to 3.4%), respectively. Children living in households without sanitation service, that is, practising open defecation (aOR=1.9, 95% CI=1.4 to 2.6), and with unimproved (aOR=1.9, 95% CI=1.3 to 2.7) and limited (aOR=1.5, 95% CI=1.1 to 2.2) services were more likely to have diarrhoea compared with children with basic sanitation services. Household access to WASH services was not associated with acute respiratory infection. CONCLUSION: We suggest reinforcing household access to basic sanitation services to combat diarrhoea in children under 5 years. Further research is needed on the effects of WASH interventions on diarrhoea and acute respiratory infection in children under 5 years.

Effects of the level of household access to water, sanitation and hygiene on the nutritional status of children under five, Benin.

BACKGROUND: Whether or not the Water, Sanitation and Hygiene (WASH) conditions in which children under five live determine their nutritional status is still under discussion. The work aimed to study the effects of household WASH conditions to which children under five are exposed on their nutritional status in Benin. METHODS: The study utilized a cross-sectional design and consisted of secondary analyses using datasets from the fifth Demographic and Health Survey (DHS-V) conducted in Benin. Stunting, wasting and underweight were the dependent variables. The WASH conditions in which children live were evaluated in the immediate environment, i.e., at the level of their households. After describing the study variables, the relationships between the dependent variables and the exposures were checked using multivariate logistic regression. Data analysis was performed with Stata 15 and took into account the survey's sampling design. RESULTS: The prevalence of stunting, wasting and underweight was 31.15% (95% CI = 29.90-32.42), 4.79% (95% CI = 4.33-5.31) and 15.82% (95% CI = 14.92-16.76), respectively. The stunting odds were 1.35 (95% CI = 1.15-1.59) and 1.27 (95% CI = 1.01-1.59) times higher for children from households with no water and sanitation services, respectively, compared to children living in households with basic water and sanitation services. Children under five from households with no hygiene facilities and using limited hygiene services had 1.31 (95% CI = 1.05-1.63) and 1.35 (95% CI = 1.10-1.67) times the odds of being stunted, respectively, compared to children covered by basic hygiene facilities. There is no evidence of a significant relationship between household access to WASH and wasting in children under five. The odds of being underweight were 1.33 (95% CI = 1.02-1.72) times higher among children under five from households with limited hygiene facilities than among children from households with basic hygiene facilities. CONCLUSION: Interventions to fight malnutrition in children under five should include a WASH dimension.

Is Benin on track to reach universal household coverage of basic water, sanitation and hygiene services by 2030?

INTRODUCTION: With the end of the Millennium Agenda, the United Nations Member States adopted the Sustainable Development Agenda in 2015. This new agenda identifies 17 Sustainable Development Goals (SDGs) and 169 targets for 2030, including Water, Sanitation and Hygiene (WASH). OBJECTIVE: To study the evolution of household access to WASH services over the last two decades in Benin and make projections for 2030. METHODS: In this study, secondary analyses were performed using the datasets of the Demographic and Health Surveys in Benin from 2001 to 2017-2018. The statistical unit was the household. The achievement of the WASH SDGs targets was monitored through the proportion of households using individual basic WASH services, the proportion of households using surface water for drinking, and the proportion of households practising open defecation. The study generated Annual Percentage Changes (APCs) for outcome variables. Based on the APCs between 2001 and 2017-2018, projections were made for 2030. RESULTS: From 2001 to 2017-2018, household access to individual basic WASH services increased from 50.54% to 63.98% (APC = +1.44%), 5.39% to 13.29% (APC = +5.62%), and 2.12% to 10.11% (APC = +9.92%), respectively. At the same time, the prevalence of surface water consumption and open defecation among households decreased from 10.54% to 5.84% (APC = -3.52%) and 67.03% to 53.91% (APC = -1.31%), respectively. If the trend observed between 2001 and 2017-2018 remains unchanged, the national coverage of households with basic individual WASH services would be 76.50%, 26.33% and 10.51%, respectively, by 2030. The prevalence of surface water consumption and open defecation among households would be 3.73% and 45.71%, respectively, by 2030. CONCLUSION: Benin achieved significant progress in household coverage of adequate WASH services over the last two decades. However, progress appears insufficient to achieve universal coverage of households with basic WASH services, and eliminate surface water consumption and open defecation by 2030. There is a need to strengthen research into the drivers of household access to adequate WASH services.

Effects of household access to water, sanitation, and hygiene services on under-five mortality in Sub-Saharan Africa.

Introduction: Sub-Saharan Africa has the highest under-five mortality rate and is among the regions where people have the least access to adequate Water, Sanitation, and Hygiene (WASH) services. The work aimed to investigate the effects of WASH conditions faced by children on under-five mortality in Sub-Saharan Africa. Methods: We carried out secondary analyses using the Demographic and Health Survey datasets of 30 countries in Sub-Saharan Africa. The study population consisted of children born within 5 years preceding the selected surveys. The dependent variable was the child's status (1 = deceased versus 0 = alive) on the survey day. The individual WASH conditions in which children live were assessed in their immediate environment, i.e., at the level of their households of residence. The other explanatory variables were related to the child, mother, household, and environment. Following a description of the study variables, we identified the predictors of under-five mortality using a mixed logistic regression. Results: The analyses involved 303,985 children. Overall, 6.36% (95% CI = 6.24-6.49) of children died before their fifth birthday. The percentage of children living in households with access to individual basic WASH services was 58.15% (95% CI = 57.51-58.78), 28.18% (95% CI = 27.74-28.63), and 17.06% (95% CI = 16.71-17.41), respectively. Children living in households using unimproved water facilities (aOR = 1.10; 95% CI = 1.04-1.16) or surface water (aOR = 1.11; 95% CI = 1.03-1.20) were more likely to die before five than those coming from households with basic water facilities. The risk of under-five mortality was 11% higher for children living in households with limited sanitation facilities (aOR = 1.11; 95% CI = 1.04-1.18) than for those with basic sanitation services. We found no evidence to support a relationship between household access to hygiene services and under-five mortality. Conclusion: Interventions to reduce under-five mortality should focus on strengthening access to basic water and sanitation services. Further studies are needed to investigate the contribution of access to basic hygiene services on under-five mortality.

Tends of "Zero-dose" children aged 12-23 months in Togo from 2000 to 2017 and predictions for 2030

Guided by the principle of leaving no one behind by improving equitable access and use of new and existing vaccines, the Immunization Agenda 2030 aims, among other things, to halve the incidence of "zero-dose" at the national level. This study aimed at studying the tends of the prevalence of "zerodose" children from 2000 to 2017 and making predictions for 2030. The study consisted of secondary data analyses from the Multiple Indicator Cluster Surveys (MICS) conducted in Togo. The study population consisted of children aged 12-23 months surveyed during MICS2 in 2000, MICS3 in 2006, MICS4 in 2010 and MICS6 in 2017. The dependent variable was the "zero-dose" vaccination status (1=Yes vs 0=No). The explanatory variables were related to the child, mother, household and environment. The study generated the overall annual percentage changes (APC) and by the independent variables. As a result, the prevalence of children with "zero-dose" expected for 2030 was estimated using Excel 2013 and Stata 16.0 software. In total, 636, 864, 916 and 952 children aged 12-23 months were included for MICS2, MICS3, MICS4 and MICS7, respectively. The prevalence of "zerodose" children decreased from 37.15% in 2000 to 31.72% in 2006, then 30.10% in 2010 and 26.86% in 2017, with an overall APC= - 1.89%. The highest relative annual decrease was from 2000 to 2006. If the historical rate of decrease remains unchanged, we predict that percentage of "zero-dose" children aged 12-23 months will be 20.96% in 2030, with a decrease of 22% compared to 2017, against a target of 50%. We suggest that strengthening strategies to increase full immunization coverage of children will contribute to reducing the percentage of zero dose children. A prerequisite will be a better understanding of the predictors of the "zero-dose" phenomenon in children

Prevalence of fatigue while driving among two-wheeled vehicle drivers and associated factors: Exploratory approach from secondary analysis based on hospital data, Benin.

Fatigue while driving is one of the risk factors of road crashes. It's still poorly considered in interventions because of insufficient literature. In addition, the literature on this issue doesn't focus on two-wheelers, the most frequent users in the Benin context. The study examined the prevalence of fatigue while driving among two-wheeled vehicle drivers and the related factors. It's a secondary baseline data analysis from a cohort of road crash victims recruited from five hospitals in Benin. Data were collected from July 2019 to January 2020. Patients who identified themselves as drivers during the accident were included. Data on individual characteristics, including fatigue status in the moments preceding the collision, and other risk factors and environmental settings, were extracted. We used multivariate logistic regression. Among the respondents, 12.20% (95% CI=10.20-14.53) reported fatigue in the moments preceding the collision. The odds of fatigue while driving were significantly higher in male drivers (aOR=3.60; 95% CI=1.08-11.98), during professional trips (aOR=2.09; 95% CI=1.30-3.37), in non-helmet wearers (aOR=1.85; 95% CI=1.09-3.13), in users of stimulants (aOR=3.13; 95% CI=1.50-6.54), in those with a history of chronic diseases (aOR=1.95; 95% CI=1.16-3.27), at dusk (aOR=4.22; 95% CI=2.22-8.02), at night (aOR=6.90; 95% CI=3.95-12.05), and on Inter-State National Roads (aOR=2.01; 95% CI=1.18-3.43). Fatigue is a risk factor for road crashes in Benin, associated with other risk factors that highlight particularly vulnerable profiles and groups. Integrating prevention policies based on these cumulative risk factors will result in efficiency improvements.

Household access to basic drinking water, sanitation and hygiene facilities: secondary analysis of data from the demographic and health survey V, 2017-2018.

BACKGROUND: In Benin, access to water, sanitation and hygiene (WASH) remains an issue. This study aims to provide an overview of household access to basic WASH services based on nationally representative data. METHOD: Secondary analyses were run using the 'HOUSEHOLD' dataset of the fifth Demographic and Health Survey 2017-2018. The dependent variables were household access to individual and combined basic WASH services. The characteristics of the household head and those related to the composition, wealth and environment of the household were independent variables. After a descriptive analysis of all study variables, multivariate logistic regression was performed to identify predictors of outcome variables. RESULTS: The study included 14,156 households. Of these, 63.98% (95% CI = 61.63-66.26), 13.28% (95% CI = 12.10-14.57) and 10.11% (95% CI = 9.19-11.11) had access to individual basic water, sanitation and hygiene facilities, respectively. Also, 3% (95% CI = 2.53-3.56) of households had access to combined basic WASH services. Overall, the richest households and few, and those headed by people aged 30 and over, female and with higher levels of education, were the most likely to have access to individual and combined basic WASH services. In addition, disparities based on the department of residence were observed. CONCLUSION: The authors suggest a multifactorial approach that addresses the identified determinants.
