Prevalence of open defecation among households with toilets and associated factors in rural south India: an analytical cross-sectional study

Mapping and predicting open defecation in Ethiopia: 2021 PMA-ET study

INTRODUCTION

There has been extensive research conducted on open defecation in Ethiopia, but a notable gap persists in comprehensively understanding the spatial variation and predictors at the household level. This study utilizes data from the 2021 Performance Monitoring for Action Ethiopia (PMA-ET) to address this gap by identifying hotspots and predictors of open defecation. Employing geographically weighted regression analysis, it goes beyond traditional models to account for spatial heterogeneity, offering a nuanced understanding of geographical variations in open defecation prevalence and its determinants. This research pinpoints hotspot areas and significant predictors, aiding policymakers and practitioners in tailoring interventions effectively. It not only fills the knowledge gap in Ethiopia but also informs global sanitation initiatives.

METHODS

The study comprised a total weighted sample of 24,747 household participants. ArcGIS version 10.7 and SaT Scan version 9.6 were used to handle mapping, hotspots, ordinary least squares, Bernoulli model analysis, and Spatial regression. Bernoulli-based model was used to analyze the purely spatial cluster detection of open defecation at the household level in Ethiopia. Ordinary Least Square (OLS) analysis and geographically weighted regression analysis were employed to assess the association between an open defecation and explanatory variables.

RESULTS

The spatial distribution of open defecation at the household level exhibited clustering (global Moran's I index value of 4.540385, coupled with a p-value of less than 0.001), with significant hotspots identified in Amhara, Afar, Harari, and parts of Dire Dawa. Spatial analysis using Kuldorff's Scan identified six clusters, with four showing statistical significance (P-value < 0.05) in Amhara, Afar, Harari, Tigray, and southwest Ethiopia. In the geographically weighted regression model, being male [coefficient = 0.87, P-value < 0.05] and having no media exposure (not watching TV or listening to the radio) [coefficient = 0.47, P-value < 0.05] emerged as statistically significant predictors of household-level open defecation in Ethiopia.

CONCLUSION

The study revealed that open defecation at the household level in Ethiopia varies across the regions, with significant hotspots identified in Amhara, Afar, Harari, and parts of Dire Dawa. Geographically weighted regression analysis highlights male participants lacking media exposure as substantial predictors of open defecation. Targeted interventions in Ethiopia should improve media exposure among males in hotspot regions, tailored sanitation programs, and region-specific awareness campaigns. Collaboration with local communities is crucial.

Prevalence of Open Defecation Practice and Associated Factors Among Households in Geshiyaro Project Implementation Sites in Ethiopia: A Cross-Sectional Study

Background

Open defecation is a significant global challenge, impacting public health, environmental sanitation, and social well-being, especially in low- and middle-income countries like Ethiopia. It is the second-largest cause of disease burden worldwide by facilitating the spread of germs that cause diarrhea diseases. Studies examining open defecation practices are insufficient, especially in areas implementing Ethiopia's Geshiyaro project. Therefore, this study aimed to assess the status of open defecation practice and associated factors in the study area.

Method

A community-based cross-sectional study was conducted from June to July 2023. The total number of households included in this study was 7995. A structured questionnaire and observational checklist were used to collect data. Descriptive and multivariate logistic regression analyses were performed using STATA version 16.

Results

The study found that 16.5% of households practiced open defecation. The following factors were significantly associated with the occurrence of open defecation: residence (AOR = 1.56, 95% CI: 1.26-1.92), education (AOR = 0.59, 95% CI: 0.49-0.72), age (AOR = 0.53, 95% CI: 0.41-0.69), knowledge on diarrhea prevention (AOR = 1.32, 95% CI: 1.17-1.50), marital status (AOR = 1.61, 95% CI: 1.32-1.97), and awareness creation about WASH services (AOR = 1.96, 95% CI: 1.71-2.25). On the other hand, no significant association was observed between the occurrence of open defecation and the household's income (AOR = 1.07, 95% CI: 0.93-1.23) or the head of household sex (AOR = 0.94, 95% CI: 0.78-1.12).

Conclusion

Open defecation remains a critical public health concern in Ethiopia's Geshiyaro project sites. Various factors influencing this practice have been identified. Targeted interventions are needed to enhance access to safe sanitation facilities and promote awareness of WASH services, aligning with SDG 3 target 3, and SDG 6 target 2.

Open defecation practice among households with latrines in rural communities of Ararso District, Somali Region, Eastern Ethiopia

Background

Open defecation contributes to the spread of different feco-oral diseases. Therefore, access to a latrine is strongly recommended, as it considerably reduces the risks. Even though provision of latrine facilities alone does not guarantee the desired health benefits, they should be integrated with behavior change. In Ethiopia, efforts have been made to increase the coverage of latrine facilities. However, evidence on how consistently households use it is limited. Most prior studies focused on latrine utilization among households, and limited evidence is available about open defecation practices among households with latrines and associated factors. Thus, this study is critical for developing effective intervention approaches to prevent open defecation among households with latrines.

Objective

The aim of this study was to assess the open defecation practice and associated factors among households with latrines in rural communities of Ararso District, Somali Region, Eastern Ethiopia, 2023.

Method

A community-based, cross-sectional study design was employed among households with latrines in the district. A total of 632 households latrines were selected using a systematic sampling technique. Data were collected using a structured questionnaire and an observational checklist. The questionnaire was designed in KoboTool box, Humanitarian Response software, and the data were collected using the Kobo Collect version 2023.2.4 mobile application. The data were downloaded from the server in the Microsoft Excel format for data cleaning before being exported to STATA version 14 for analysis. Bivariate and multivariable analyses were employed to investigate the relationship between outcome and independent variables. Odd ratios with 95% confidence intervals were utilized to assess the association between the outcome and the predictor variables. A P-value of <0.05 was used as the threshold point for statistical significance.

Result

In this study, the prevalence of open defecation practice among households with latrines was 32.4% (95% CI: 28.1, 35.9). Sex of the household (AOR = 1.60, 95% CI: 1.06, 2.4), educational status (AOR = 2.40, 95% CI: 1.08, 5.53), family size (AOR = 1.62, 95% CI: 1.22, 2.78), the presence of under-5-year-old children in the house (AOR = 1.84, 95% CI: 1.19, 2.75), the need for latrine maintenance (AOR = 2.37.95% CI: 1.62, 3.48), current status of the latrine (AOR = 2.37, 95% CI: 1.62, 3.48), and latrine cleanness status (being unclean) (AOR = 1.91, 95% CI: 1.29, 2.81) were significantly associated with open defecation practice among households with latrine.

Conclusion

The study concluded that open defecation was significantly practiced by households with latrines. This revealed that the presence of a latrine alone was insufficient to considerably reduce open defecation. To alleviate this problem, the government and health workers, in collaboration with the health bureau, should promote frequent sanitation and hygiene education in the communities.

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.

Barriers of household toilet utilization among toilet owners in a rural area of Northern India: An analytical cross-sectional study

Background

Open defecation continues to prevail among toilet owners despite effective implementation of the Swachh Bharat Mission (Gramin). We conducted this study to determine toilet utilization rates and learn about the barriers to toilet use in the rural areas. By understanding the barriers, physicians can provide targeted education and become better equipped to manage their patients' conditions and advocate for their demands.

Materials and Methods

We conducted a cross-sectional study on the households of the rural field practice areas of the department in central Uttar Pradesh by the census method. House listing was procured from the departmental records. The questionnaire was directed at both the household level and individual level.

Results

The proportion of households with access to a toilet was found to be 91.1% of which 504 households were included in the study. Among the toilet owners, 115 (22.8%) households were not using toilets exclusively by all the members. At the individual level, age groups (of 20-59 years, and ≥60 years) and female gender were found to be significantly associated with open defecation. At the household level, government assistance for toilet construction and livestock keeping was found to be associated with open defecation. Major barriers to toilet use were childhood habits, dearth of toilets in the farming grounds/workplace, women during menstruation and having a non-functional toilet.

Conclusion

This study indicates that merely installing a household toilet does not ensure exclusive utilization of toilet and the practice of open defecation might continue to be prevalent if corrective measures are not undertaken.

The Use of Sanitary Latrines and the Practice of Open-Air Defecation in a Rural Setup in Perambalur District: A Cross-Sectional Study

Background Public health initiatives aim to decrease infectious diseases by enhancing sanitation, which is their primary goal. The practice of sporadically contaminating the environment with human feces has been around for generations and is embedded in the cultural behavior of villagers in India. This study aimed to estimate the proportion of people with access to latrine facilities and the proportion of people who practice open defecation in the villages of Perambalur, Tamil Nadu. Methodology This community-based, cross-sectional, analytical study was conducted in two rural villages in the Perambalur district for six months. After obtaining approval from the institutional ethics committee, we informed participants about the study's purpose. We conducted the study in selected rural areas and included every single residence in the hamlet, irrespective of whether the residents were permanent or temporary. We did not include families that were not reachable at any point during the survey. A convenient sampling procedure was used to select 330 houses for the study. The lead investigator interviewed one individual from each household, preferably the head of the family. A semi-structured questionnaire was used to collect the pertinent information. All collected data were entered into Microsoft Excel (Microsoft Corp., Redmond, WA, USA), and SPSS software version 21 (IBM Corp., Armonk, NY, USA) was used to analyze the results. Results Only around 3.6% of the study participants lived in kutcha households, and about 99.1% of participants identified as Hindu. The proportion of household latrines used was 64.1% among the study participants. Of them, 52.3% engaged in open defecation. Only 4.7% of participants had access to an underground drainage system. Most participants gained knowledge from medical professionals (84.8%). Social media was the second most used source, accounting for about 60.7% of the total. The most frequent reason given for practicing open-air defecation was the perception that constructing restrooms would be expensive (76.3%), while the second most frequent reason was a lack of land (53.4%). An independent t-test found no statistically significant relationship between the availability of household latrines and the number of girls or boys, age, or family income. Compared to those living in semi-pucca and kutcha households, most participants (77.3%) who lived in pucca houses had household latrines. The chi-square test revealed that this proportional difference was statistically significant (p = 0.0001). Conclusions The study participants used household latrines 64.1% of the time. Of the participants, 52.3% engaged in open defecation. The government's initiative to build toilets has only helped a quarter of the population, which needs to be improved. Only 5% of people living in rural areas have access to an underground drainage system. The results of our study provide a justification for the government program's mandate that healthcare practitioners must deliver health education. Therefore, a personalized approach is required to overcome the behavioral barrier among rural people and achieve behavior change.

A review of rural and peri-urban sanitation infrastructure in South-East Asia and the Western Pacific: Highlighting regional inequalities and limited data

Rural and peri-urban communities in developing countries rely on sanitation systems which are often unsafely managed. One of the major barriers to assess safely managed sanitation is a lack of data about the existing sanitation infrastructure and levels of containment safety. The aim was to review rural and peri-urban on-site sanitation studies in order to understand different infrastructure types, associated management practices and any impacts on human health. The scope was limited to South-East Asia and Western Pacific regions in order to better identify regional inequalities. Among the 155 reviewed articles, 73 studies (47%) linked sanitation infrastructure to poor human health. Nearly all articles reported latrine ownership (n = 149, 96%) while sanitation infrastructure types were covered less frequently (n = 104, 67%). In particular, there was a lack of published literature describing back-end characteristics (dimension and materials) (n = 12, 8%) and/or management practices (n = 4, 3%). This stems from a limited application of research methodologies that characterise sanitation infrastructure and faecal sludge management (containment, emptying and on-site treatment). Inequality between regions was prevalent with three quarters of the studies on latrine back-end infrastructure from Bangladesh and India in South-East Asia. A strategic research approach is needed to address the current knowledge gaps regarding sanitation infrastructure and safe faecal sludge management.

Household sanitation and menstrual hygiene management among women: Evidence from household survey under Swachh Bharat (Clean India) Mission in rural Odisha, India

Introduction

Discussion on women empowerment without addressing their basic needs would be meaningless. As such, the needs of women and girls have been prioritized in global sanitation efforts including menstrual hygiene. However, there is little research on existing approaches on menstrual management. India's most ambitious sanitation campaign named Swachh Bharat Mission or "Clean India Mission" aimed to achieve universal sanitation coverage in every single household, targeted to end open defecation by October 02, 2019. This study aimed to assess the women's perception of household sanitation facilities and menstrual hygiene management experience in Odisha under Swachh Bharat Mission.

Methods

The study is a community-based survey having cross-sectional in nature conducted among 700 rural women and girls aged 15-45 years in the Balesore district of Odisha state in India from January to April 2021. A multi-stage sampling method was adopted to select the study participants. Data was collected using a pretested questionnaire based on the Performance Monitoring and Accountability 2020 survey questionnaire and analyzed by SPSS version 25. Descriptive statistics was used to assess the household sanitation and menstrual hygiene management experience among women.

Results

More than two-thirds (68.4%) of rural households use improved sanitation facilities. Around 30% of families have inadequate sanitation infrastructure, which means at least one household member defecates in the open space. Nearly 64.6% disposed of their menstrual absorbents in the bush or field, while 29.1% disposed in the river and 24.1% in the waste bin. Still, 40.6% of women were using clothes as menstrual absorbents, and 54.9% of the respondents reported washing their menstrual materials for re-use. Of those who washed and re-used, 99.2% said their re-use material was completely dry before re-use. About 69.7% of the respondents mentioned that they change their menstrual absorbents in sleeping areas at home. About 91% of the respondents reported that the place where they changed their menstrual absorbents was safe, clean, and private. Only 22.5% of women responded to having water and soap at their menstruation management area.

Conclusion

The effort for improvements in sanitary techniques during menstruation is partly effective in creating healthy behavior. The current strategy for developing programs to adopt menstrual hygiene measures needs a bottom-up approach with women at the center. Components associated with menstrual hygiene management, such as women's cleanliness, water supply, and the availability and accessibility of disposable sanitary napkins, should be given specific attention. It is essential to acknowledge the issues like toilet construction and behavior change communication to consolidate the gains in an era of "Clean India Mission."

Contextual and psychological factors influencing open defecation free status: an exploratory qualitative study in rural South Western Uganda

INTRODUCTION

Achieving the Open defecation free (ODF) status remains a major challenge in Uganda, yet it contributes significantly to child health improvement. Literature on social, cultural and behavioral aspects that influence the ODF status in rural Uganda is limited. The study therefore, explored perceived factors influencing the ODF status in rural South Western Uganda.

METHODS

An exploratory study employing qualitative techniques and based on deductive analysis between month December 2020 and January 2021 was conducted. Seven Focus Group Discussions (FGDs and three Key Informant Interviews (KIs) were conducted in Kabale District, southwestern Uganda. Focus Group Discussion participants were mothers and fathers having children of 2 years and below while KIIs included local community leaders and health extension workers. Data was analyzed using a categorization matrix derived from the Risks, Attitudes, Norms, Abilities, and Self-regulation (RANAS) model which is comprised of contextual and psychological factors. Text was further categorized into high and low statements for attainment of ODF status.

RESULTS

The contextual factors influencing the Open Defecation Free status behavior included; farming activities far from home, financial constraints, rainy seasons, collapsible soft soils, and alcohol use. Psychological factors influencing ODF status included; perceived health risk for typhoid disease, low perceived severity for lack of ODF components, negative attitude of less value attached to ODF components, and a feeling of time wastage practicing ODF status behavior. The perception that the community has the ability to attain the ODF status was high. Although, the capability to maintain ODF was low when it comes to replacement of ODF component if stolen or destroyed.

CONCLUSION

Open Defecation Free status is influenced by contextual and psychological factors. Therefore, it's crucial for sanitation promotors to always identify such context specific factors in order to design sanitation and hygiene promotion interventions to address the ODF free status related challenges.

Soil-transmitted helminth infections after mass drug administration for lymphatic filariasis in rural southern India

OBJECTIVES

Targeted deworming is the current strategy for control of morbidity associated with soil-transmitted helminths (STH) among at-risk populations: preschool-aged children, school-aged children and women of childbearing age. We report the prevalence and intensity of STH in a district after lymphatic filariasis (LF) mass drug administration (MDA) in southern India where albendazole was co-administered from 2001.

METHODS

Children aged 2 to 15 years and adults (defined as ≥15 years) in a rural administrative block of Tamil Nadu were recruited using a probability proportional to size method. Stool samples were screened and eggs per gram (EPG) determined by Kato-Katz method. Multilevel logistic regression (MLR) and multilevel negative binomial regression (MNBR) analyses were used to identify factors associated with infection and intensity, respectively.

RESULTS

Of 862 participants who provided samples, 60 (7.0%; 95% confidence interval (CI): 5.3-8.7) were positive for STH with a predominance of hookworm infections (n = 57, 6.6%; 95% CI: 5.0-8.3). Increasing age (odds ratio (OR): 1.09; 95% CI: 1.04-1.15) and regular usage of the toilet (OR: 0.32; 95% CI: 0.12-0.88) were independently associated with hookworm infection and age was significantly associated with increasing intensity of hookworm infection (infection intensity ratio (IIR): 1.28; 95% CI: 1.19-1.37). A brief review of STH prevalence in endemic settings before and after the stoppage of LF MDA indicated that, in most settings, a substantial reduction in STH prevalence is seen.

CONCLUSION

Community-wide MDA in all age groups in these post-LF MDA districts with low prevalence and light intensity infections could result in transmission interruption of STH.

Having a latrine facility is not a guarantee for eliminating open defecation owing to socio-demographic and environmental factors: The case of Machakel district in Ethiopia

Background

Open defecation practice problem is rampant in most rural areas of developing countries, including Ethiopia. To combat this problem, the Ethiopian government implemented different sanitation interventions including Community-Led Total Sanitation and Hygiene (CLTSH). The CLTSH approach is mainly aimed to eradicate open defecation practice through mobilizing the community to construct a latrine facility and utilize it. Although this intervention has significantly improved households’ access to a latrine facility, its impact on bringing behavioral change such as avoiding open defecation is not well studied.

Objective

Our study aimed to assess the prevalence of open defecation among households having their latrine and its determinant factors in rural settings in Northwest Ethiopia.

Methods

A community-based cross-sectional study was conducted in Machakal district from September 1 to 30, 2019. A total of 472 household heads who had a latrine facility and systematically selected from six rural Kebeles of the district, were involved in the study. The data were collected using a structured questionnaire and observational checklist tools through face-to-face interviews and observation methods. Bivariate and multivariable logistic regression models were run to identify the factors that influence open defecation practice. During the multivariable analysis, statistical significance was declared at the p-value of <0.05 with 95% CI.

Results

The prevalence of open defecation practice among household heads who had latrine facility was 27.8% (95% CI, [23.1–32.8]). Female gender (AOR = 2.94, 95% CI [1.13–7.68]), not attending of formal education (AOR = 3.10, CI 95% [1.34–7.13]), having >5 family members (AOR = 1.72, CI 95% [1.05–2.80]), presence of under-five child (AOR = 3.64 CI 95% [2.14–6.21]), preferring leaf as anal cleaning material (AOR = 3.18, CI 95% [1.67–6.08]), having unclean latrine (AOR = 2.15, CI 95% [1.34–3.44]), and having latrine that needs maintenance (AOR = 2.50 CI 95% [1.52–4.11]) variables were associated with open defecation practice.

Conclusions

Among the total respondents, finding more than a quarter of open defecators is concerning for a district that achieved greatly in terms of latrine coverage. This indicates the above-mentioned factors contributed to influence household heads to defecate openly despite having latrines. Therefore, the government and partners need to focus on designing strategies that effectively address determinant factors of open defecation.

Comparing Reproductive Health Awareness, Nutrition, and Hygiene among Early and Late Adolescents from Marginalized Populations of India: A Community-Based Cross-Sectional Survey

Adolescence (10–19 years) is marked by many physiological changes and is vulnerable to health and nutritional problems. Adolescence, particularly, early adolescence is inadequately addressed in our national surveys. The present study aimed to assess the reproductive health awareness, nutrition, and hygiene of marginalized adolescent girls and boys and compare them among early and late adolescents. Our cross-sectional study was a part of a community-based project across India’s five zones, namely North, East, West, Central, and South. Unadjusted and adjusted logistic regression was performed to compare awareness about HIV/AIDS, or Sexually Transmitted Infections (STI), consumption of Iron Folic Acid (IFA) tablets and three meals in a day, safe menstrual hygiene practices, history of anemia, and open defecation practice among early and late adolescents. Data were reported as unadjusted and adjusted odds ratio (aOR) with a 95% confidence interval (95% CI). Among early adolescents, around 58% of girls and boys did not consume IFA tablets, and 28% of girls and 24% of boys defecated in the open. Compared to late adolescents, early adolescent girls had lower odds of awareness about HIV/AIDS (aOR (95% CI): 0.50 (0.47–0.54)) and open defecation (aOR (95% CI): 0.90 (0.83–0.98)) and higher odds of hand hygiene after defecation (aOR (95% CI): 1.52 (1.37–1.68)) and safe menstrual practices (aOR (95% CI): 1.42 (1.23–1.64)). There is a dire need to start public health interventions from early adolescence for long-term benefits throughout adolescence.

Norms and Social Network-Centric Behavior Change Intervention (Nam Nalavazhvu) for Improved Toilet Usage in Peri-Urban Communities of Tamil Nadu: Protocol for a Cluster-Randomized Controlled Trial

BACKGROUND

Inconsistent toilet usage is a continuing challenge in India. Despite the impact of social expectations on toilet usage, few programs and studies have developed theoretically grounded norm-centric behavior change interventions to increase toilet use in low-income settings.

OBJECTIVE

The objective of this paper is to detail the rationale and design of an ex ante, parallel cluster-randomized trial evaluating the impact of a demand-side, norm-centric behavior change intervention on exclusive toilet use and maintenance in peri-urban Tamil Nadu, India.

METHODS

Following formative research, we developed an evidence-based norm-centric behavior change intervention called Nam Nalavazhvu (Tamil for "our well-being"). The multilevel intervention aims to improve toilet usage by shifting empirical expectations or beliefs about other relevant people's sanitation practices. It also provides action-oriented information to aid individuals to set goals and overcome barriers to own, consistently use, and maintain their toilets. This trial includes 76 wards in the Pudukkottai and Karur districts, where half were randomly assigned to receive the intervention and the remaining served as counterfactuals.

RESULTS

We enrolled wards and conducted a baseline survey among randomly selected individuals in all 76 wards. The 1-year behavior change intervention is currently ongoing. At the endline, we will collect relevant data and compare results between study arms to determine the impacts of the Nam Nalavazhvu intervention on sanitation-related behavioral, health, and well-being outcomes and potential moderators. This study is powered to detect differences in the prevalence of exclusive toilet use between study arms. We are also conducting a process evaluation to understand the extent to which the intervention was implemented as designed, given the special pandemic context.

CONCLUSIONS

Findings from this trial will inform norm-centric behavior change strategies to improve exclusive toilet usage.

Historical analysis of inverse correlation between soil-transmitted helminthiasis and pancreatic cancer

In this descriptive epidemiological study, the soil-transmitted helminth (STH) burden and pancreatic cancer (PC) mortality rates of different countries and peoples are compared to demonstrate an inverse correlation. Formerly ubiquitous helminth infection possibly played a significant role in defending the human host against PC until the advancement of modern hygiene, with helminth eradication in recent times in developed countries and urban centers. It is posited that a high rate of infection by STH in developing countries and rural areas protects the human host from the development of PC, possibly by immune modulation. This hypothesis is used to explain increased PC rates in minority groups in the United States who had decreased helminth exposure in the late 20th century.

Hygienic Risk Exposures Across Ethnic Groups in Rural Areas of Guangxi, China: Prevalence, Associated Factors, and Perceptions of Policy

BACKGROUND

Controlling hygienic risk exposures (HREs) is important for reducing acute respiratory infection or parasitic infection; however, studies across vulnerable ethnicities are limited. This study aimed to identify the prevalence and associated factors of HREs and perception on HRE policies among ethnic groups in Guangxi, China.

METHODS

A community-based cross-sectional study was conducted in rural areas of Guangxi, China, among Han majority and Zhuang, Yao, Miao, Dong, Mulao, and Maonan minorities. The prevalence of HREs and perceptions concerning the HRE policies were presented using descriptive statistics. Associated factors were analyzed using a logistic regression model, and adjusted prevalence ratios and 95% confidence interval were calculated.

RESULTS

High prevalence of HREs on hand and soil hygiene were found in all ethnicities. Miao minority had the highest prevalence of HREs, particularly in poor hand washing (74.1%), infrequent nail clipping (90.4%), and outdoor soil contact (92.7%), compared with the others. Prevalence of HREs in some ethnic minority groups were significantly different from those in Han majority after adjusted with other significant factors. Village leaders were more aware of existing national and community regulations related to HREs than household heads. Village leaders and household heads of almost all ethnic groups perceived high policy's compliance in their village or household on avoiding fertilizing with farmyard manure.

CONCLUSIONS

HREs were prevalent in all ethnic groups, especially in Miao minority. Ethnicity, one of social determinants, was significantly associated with HREs. Raising awareness at both the village and household levels on HREs is needed for all ethnic groups.

The improved and the unimproved: Factors influencing sanitation and diarrhoea in a peri-urban settlement of Lusaka, Zambia

Accounting for peri-urban sanitation poses a unique challenge due to its high density, unplanned stature, with limited space and funding for conventional sanitation instalment. To better understand users, needs and inform peri-urban sanitation policy, our study used multivariate stepwise logistic regression to assess the factors associated with use of improved (toilet) and unimproved (chamber) sanitation facilities among peri-urban residents. We analysed data from 205 household heads in 1 peri-urban settlement of Lusaka, Zambia on socio-demographics (economic status, education level, marital status, etc.), household sanitation characteristics (toilet facility, ownership and management) and household diarrhoea prevalence. Household water, sanitation and hygiene (WASH) facilities were assessed based on WHO-UNICEF criteria. Of particular interest was the simultaneous use of toilet facilities and chambers, an alternative form of unimproved sanitation with focus towards all-in-one suitable alternatives. Findings revealed that having a regular income, private toilet facility, improved drinking water and handwashing facility were all positively correlated to having an improved toilet facility. Interestingly, both improved toilets and chambers indicated increased odds for diarrhoea prevalence. Odds of chamber usage were also higher for females and users of unimproved toilet facilities. Moreover, when toilets were owned by residents, and hygiene was managed externally, use of chambers was more likely. Findings finally revealed higher diarrhoea prevalence for toilets with more users. Results highlight the need for a holistic, simultaneous approach to WASH for overall success in sanitation. To better access and increase peri-urban sanitation, this study recommends a separate sanitation ladder for high density areas which considers improved private and shared facilities, toilet management and all-inclusive usage (cancelling unimproved alternatives). It further calls for financial plans supporting urban poor access to basic sanitation and increased education on toilet facility models, hygiene, management and risk to help with choice and proper facility use to maximize toilet use benefit.

Evaluating the declarations of open defecation free status under the Swachh Bharat (‘Clean India’) Mission: repeated cross-sectional surveys in Rajasthan, India

Background

The most ambitious sanitation campaign to end open defecation (OD) in India came to a close on 2 October 2019 and there are limited independent, robust data to measure its success. We aimed to evaluate Rajasthan’s claim of open defecation free status in March 2018 under the Swachh Bharat Mission (SBM) or ‘Clean India Mission’ by measuring OD trends from 2016 to 2018.

Methods

We used publicly available data from Performance Monitoring and Accountability 2020, a representative survey with two-stage stratified cluster sampling. Enumeration areas were the primary sampling units selected by the probability proportional ­to ­size method. The repeated cross-sectional surveys independently collected household water and sanitation data in Rajasthan (n=20 485). Among households reporting toilet access, the data were pooled across the four rounds for an observational analysis using logistic regression. The primary outcome measure was regular OD among households with access to toilet facilities.

Findings

Between October 2016 and July 2018 main OD practices in rural Rajasthan households decreased from 63.3% (95% CI 57.0% to 69.6%) to 45.8% (95% CI 38.4% to 53.2%) and in urban households from 12.6% (95% CI 6.0% to 19.1%) to 9.4% (95% CI 4.0% to 14.7%). Households with regular OD occurring despite access to a toilet made up 21.7% (95% CI 16.9% to 26.6%) of rural and 12.1% (95% CI 3.6% to 20.7%) of urban Rajasthan as of July 2018. The multivariate logistic regression revealed that factors related to water stress and sanitation sharing were associated with household members regularly practising OD.

Conclusions

These data highlight the importance of a continued focus on constructing toilets that are affordable with low water requirements during the next phase of SBM. An independent survey that can provide robust estimates of OD is needed to monitor progress of toilet construction and use.

Purity, Pollution, and Space: Barriers to Latrine Adoption in Post-disaster India

This study examines the adoption of latrines provided as part of reconstruction efforts after the 2004 tsunami in India. Primary data from 274 households encompassing 1154 individuals were collected from 14 villages. GLM and GLMM tests indicate that sex (more females adopted than males) is a statistically significant factor in latrine adoption (p = 0.046 and p = 0.005, respectively), while income, education, and male age cohorts were significant only in the GLM model. Regression analyses show that six social and demographic variables are somewhat predictive of latrine usage (R² = 0.123). Thus, while quantitative methods provided a contextual summation, qualitative methods ultimately explained why individuals chose to adopt or abandon the latrines. Interviews (n = 76) and focus group discussions (n = 14) revealed that latrine adoption is influenced by cultural conceptualizations of purity, pollution, and space. For example, conceptualizations of purity and pollution led some households to deem latrines as profane and thus a barrier to the entry of gods, while spatial constraints forced others to convert latrine space to other beneficial uses (e.g., puja room and storage area). Finally, the cost of pumping septic tanks and shared infrastructure arose as barriers to latrine adoption. These barriers underscore the importance of economics as well as community demand, capacity, and cohesion in latrine adoption.

Measuring open defecation in India using survey questions: evidence from a randomised survey experiment

OBJECTIVES

To investigate differences in reported open defecation between a question about latrine use or open defecation for every household member and a household-level question.

SETTING

Rural India is home to most of the world's open defecation. India's Demographic and Health Survey (DHS) 2015-2016 estimates that 54% of households in rural India defecate in the open. This measure is based on a question asking about the behaviour of all household members in one question. Yet, studies in rural India find substantial open defecation among individuals living in households with latrines, suggesting that household-level questions underestimate true open defecation.

PARTICIPANTS

In 2018, we randomly assigned latrine-owning households in rural parts of four Indian states to receive one of two survey modules measuring sanitation behaviour. 1215 households were asked about latrine use or open defecation individually for every household member. 1216 households were asked the household-level question used in India's DHS: what type of facility do members of the household usually use?

RESULTS

We compare reported open defecation between households asked the individual-level questions and those asked the household-level question. Using two methods for comparing open defecation by question type, the individual-level question found 20-21 (95% CI 16 to 25 for both estimates) percentage points more open defecation than the household-level question, among all households, and 28-29 (95% CI 22 to 35 for both estimates) percentage points more open defecation among households that received assistance to construct their latrines.

CONCLUSIONS

We provide the first evidence that individual-level questions find more open defecation than household-level questions. Because reducing open defecation in India is essential to meeting the Sustainable Development Goals, and exposure to open defecation has consequences for child mortality and development, it is essential to accurately monitor its progress.
