Sahiledengle B, Petrucka P, Desta F, Sintayehu Y, Mesfin T, Mwanri L. Childhood undernutrition mediates the relationship between open defecation with anemia among Ethiopian children: a nationally representative cross-sectional study. BMC Public Health 2024; 24:1484. [PMID: 38831296 PMCID: PMC11145842 DOI: 10.1186/s12889-024-18931-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 05/23/2024] [Indexed: 06/05/2024] Open
Abstract
BACKGROUND Poor sanitation and/or open defecation are a significant public health problem in Ethiopia, where access to improved sanitation facilities is still limited. There is a growing body of literature about the effect of open defecation on children's linear growth failure. However, very few studies about the effects of open defecation on child anemia exist. In this study, we examine whether childhood undernutrition (i.e. stunting, wasting, and underweight) mediates the relationship between open defecation and childhood anemia in children aged 6-59 months in Ethiopia. METHODS We used pooled Ethiopia Demographic and Health Survey data (2005-2016) comprising 21,918 (weighted data) children aged 6-59 months. Anemia was defined as an altitude-adjusted hemoglobin (Hb) level of less than 11 g/deciliter (g/dl) for children under 5 years. Childhood undernutrition was assessed using height-for-age Z-scores (HAZ), weight-for-age Z-scores (WAZ), and weight-for-height Z-scores (WHZ) for stunting, wasting, and underweight respectively. Mediation effects were calculated using the bootstrap and the indirect effect was considered significant when the 95% bootstrap confidence intervals (95% CI) did not contain zero. Moreover, separate multilevel regression analyses were used to explore the statistical association between open defecation and child anemia, after adjusting for potential confounders. RESULTS Our analysis revealed that nearly half (49.6%) of children aged 6 to 59 months were anemic, 46.8% were stunted, 9.9% were wasted, and 29.5% were underweight. Additionally, 45.1% of children belonged to households that practiced open defecation (OD). Open defecation was associated with anemia (AOR: 1.28; 95% CI: 1.18-1.39) and it positively predicted anemia with direct effect of β = 0.233, p < 0.001. Childhood undernutrition showed a partial mediating role in the relationship between OD and anemia. Analyzing the indirect effects, results revealed that child undernutrition significantly mediated the relationship between open defecation and anemia (stunting (βindirect = 0.014, p < 0.001), wasting (βindirect = 0.009, p = 0.002), and underweight (βindirect = 0.012, p < 0.001)). When the mediating role of child undernutrition was accounted for, open defecation had a positive impact on anemia with a total effect of βtotal = 0.285, p < 0.001. CONCLUSION Open defecation showed a significant direct effect on anemia. Child undernutrition remarkably mediated the relationship between OD and anemia that further magnified the effect. This finding has an important programmatic implication calling for strengthened, accelerated and large-scale implementation of strategies to end open defecation and achieve universal access to sanitation in Ethiopia.

Int J Geriatr Psychiatry 2024; 39:e6110. [PMID: 38831201 DOI: 10.1002/gps.6110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 05/23/2024] [Indexed: 06/05/2024]
Abstract
OBJECTIVES To explore the association between drinking water sources and cognitive functioning among older adults residing in rural China. METHODS Data were extracted from the 2008-2018 Chinese Longitudinal Healthy Longevity Survey. Drinking water sources were categorized according to whether purification measures were employed. The Chinese version of the Mini-Mental State Examination was used for cognitive functioning assessment, and the score of <24 was considered as having cognitive dysfunction. Cox regression analyses were conducted to derive hazard ratios (HRs) and 95% confidence intervals (CIs) for the effects of various drinking water sources, changes in such sources, and its interaction with exercise on cognition dysfunction. RESULTS We included 2304 respondents aged 79.67 ± 10.02 years; of them, 1084 (44.49%) were men. Our adjusted model revealed that respondents consistently drinking tap water were 21% less likely to experience cognitive dysfunction compared with those drinking untreated water (HR = 0.79, 95% CI: 0.70-0.90). Respondents transitioning from natural to tap water showed were 33% less likely to experience cognitive dysfunction (HR = 0.67, 95% CI: 0.58-0.78). Moreover, the HR (95% CI) for the interaction between drinking tap water and exercising was 0.86 (0.75-1.00) when compared with that between drinking untreated water and not exercising. All results adjusted for age, occupation, exercise, and body mass index. CONCLUSIONS Prolonged tap water consumption and switching from untreated water to tap water were associated with a decreased risk of cognitive dysfunction in older individuals. Additionally, exercising and drinking tap water was synergistically associated with the low incidence of cognitive dysfunction. These findings demonstrate the importance of prioritizing drinking water health in rural areas, indicating that purified tap water can enhance cognitive function among older adults.

Abstract
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.

Abstract
Background Inappropriate feces disposal leads to environmental contamination, and increases the risk of exposure to children. We aimed to estimate the proportion of rural households with knowledge and practice of safe management of feces (SMoF) among under-five children and to identify associated factors. Materials and Methods A cross-sectional study was conducted in eight villages in Bengaluru Urban district over 2 months, using a face-validated semi-structured interview schedule. SMoF was defined based on five criteria - defecation site, transport tool, feces disposal, cleaning of transport tool, and hand washing. Results Out of 320 under-five children surveyed, 15.7% were pre-ambulatory and 84.3% were ambulatory. The majority of the caregivers (92.5%) felt that children should defecate in the latrine and only 23.7% were aware that child feces were more infectious than adult feces. SMoF was only practiced by caregivers of ambulatory children (52.6%). Households with older caregivers (P = 0.01) and those living in a pucca house (P = 0.02) with a latrine inside (P = 0.04) were found to practice SMoF. Children of households that practiced unsafe disposal of child feces experienced more diarrheal episodes (P = 0.04). Caregivers >20 years were found to have better odds of SMoF [20-25 years (adjusted odds ratio, aOR: 9.02), 26-30 years (aOR: 12.17), >30 years (aOR: 8.93)] compared to those <20 years. Conclusion The proportion of households with knowledge and practice of SMoF was low. Awareness of SMoF is essential to reduce the incidence of diarrheal diseases and improve sanitation. Our findings also call for awareness building at schools and colleges.

Abstract
This study assessed the sanitary condition and quality of selected wells and boreholes in Shika, Zaria Nigeria. Fifty samples each were collected during the dry and wet seasons. This involved sanitary survey, water quality assessment, isolation and characterization of Shiga toxin-producing Escherichia coli O157:H7 (STEC) and, antibiogram assay. Based on the risk of contamination, wells (72%) had a high risk of contamination, while boreholes (44%) had low risk of contamination. Their physicochemical quality varied with season and location, and mean total coliform (TC) and faecal coliform (FC) were significantly lower in the dry season (p < 0.05). STEC were isolated from only wells with a prevalence of 4%, and exhibited a multidrug resistance pattern (amoxicillin, erythromycin and tetracycline). There was a strong positive correlation between sanitary status and water quality. The high- and very high-risk categories (wells) were strongly correlated with TC, FC, BOD, phosphate, turbidity and pH. .

Abstract
Globally, the deterioration of drinking water quality is a major public health problem that contributes to the spread of disease and causes death. Therefore, it is important to have regular quality control monitoring. This study aimed to assess the level of physicochemical and bacteriological quality of household drinking water and its contributing factors in flood-prone settlements of South Gondar Zone, Ethiopia. A community-based cross-sectional study was conducted in flood-prone settings of Northwest Ethiopia from January 17 to March 30, 2021. Structured questionnaires were used to gather the sociodemographic, environmental, and behavioral data. A total of 675 drinking water samples were collected from water storage containers of selected households. Logistic regression models were used for both univariate and multivariable studies. The survey included a total of 675 households. The mean values of pH (5.9 ± 1.03), turbidity (6.7 ± 2.21 NTU), and free residual chlorine (0.02 ± 0.01 mg/l) did not meet the WHO recommended limits for drinking water. The prevalence of fecal contamination of drinking water in the study area was 62.2% with [95% CI (53-60%)]. Family size [AOR = 2.205, 95% CI (1.375-3.536), absence of latrine [AOR = 3.449, 95% CI (1.349-8.823)], and lack of a separate container to draw water from its storage [AOR = 0.454, 95% CI (0.249-0.827)] were significant predictors for fecal contamination of household drinking water. In conclusion, the water quality in terms of pH, turbidity, residual chlorine, and bacteriological parameters was poor and not suitable for consumption. High prevalence of fecal contamination of water was found, and it was significantly associated with family size, the absence of a latrine, and the lack of a separate cap to take water from the storage. Therefore, continuous chlorination and monitoring its concentration, educating the community on how to use stored water, educating the advantage of having a latrine, and promoting point-of-use treatments such as filtration and boiling are needed.

Abstract
Climate change has become a global issue and affects various regions at different levels. The hydro-climatic conditions and the natural fragility of Sub-Saharan Africa (SSA) make it prone to floods. The review was intended to comprehensively explore the determinants of floods in the continent and their effects on public health. An extensive systematic literature search in English was conducted for peer-reviewed papers, abstracts and internet articles, grey literature, and official Government documents and analysed to identify common themes, findings, and outcomes. Finally, the findings were categorized into common themes. The review revealed that the frequency and intensity of precipitations have increased in recent decades in SSA. This is worsened by anthropogenic activities including urban sprawl, population growth, and land use changes. The health effects of floods are diverse, varied, and specific to a particular context which can be immediate and long-term. The economic losses due to the flood events in the continent are huge. In conclusion, Governments across the continent need to give flood management a top priority as part of national disaster preparedness, response, and mitigation. Floods cannot be managed in isolation; it has to be incorporated into national urban planning with urbanization to make cities resilient and sustainable.

Abstract
BACKGROUND Globally, there were about 50.8 million internally displaced people in 2020, of whom 42% were in sub-Saharan Africa. In areas where there are conflicts, the humanitarian emergency makes infectious disease management extremely complex. Soil-transmitted helminths (STHs) are among the most common infections globally including in Ethiopia that thrives during complex emergencies. However, with regards to STHs, studies in the context of conflict areas have not been documented in Ethiopia. METHODS In southern Ethiopia, a community-based cross-sectional study design was employed. Simple random sampling method was used to enroll a total of 405 under-fives. Structured questionnaire was used to collect data. Kato-Katz technique was used to examine stool specimens for Ascaris lumbricoides, Trichuris trichiura and hookworm spp. The Z-score for stunting, wasting and underweight were computed using the World Health Organization anthroprocedures. RESULTS The respective prevalence of soil-transmitted helminths infection and malnutrition was 67.4% (273) and 54.2% (219). Ascaris lumbricoides was the predominant helminth parasite with a prevalence of 90%, followed by T. trichiura (12%) and hookworm spp. (5%). STHs infection was significantly associated with under-nutrition (AOR: 1.88, CI 1.22-2.90) and internal displacement (AOR: 3.08, CI 1.17-8.09). Infection with A. lumbricoides was associated with both stunting and wasting (AOR: 3.04, CI 1.48-6.26) and (AOR: 3.51, CI 1.79-6.91), respectively. CONCLUSIONS Both soil-transmitted helminths and malnutrition were important public health problems among under-fives in the present conflict affected areas. Internal displacement, unimproved water, absence of latrine and sanitary services were among significant determinants for STH infections.

Abstract
Background Floods have affected 2.3 billion people worldwide in the last 20 years, and are associated with a wide range of negative health outcomes. Climate change is projected to increase the number of people exposed to floods due to more variable precipitation and rising sea levels. Vulnerability to floods is highly dependent on economic wellbeing and other societal factors. Therefore, this systematic review synthesizes the evidence on health effects of flood exposure among the population of sub-Saharan Africa. Methods We systematically searched two databases, Web of Science and PubMed, to find published articles. We included studies that (1) were published in English from 2010 onwards, (2) presented associations between flood exposure and health indicators, (3) focused on sub-Saharan Africa, and (4) relied on a controlled study design, such as cohort studies, case-control studies, cross-sectional studies, or quasi-experimental approaches with a suitable comparator, for instance individuals who were not exposed to or affected by floods or individuals prior to experiencing a flood. Results Out of 2306 screened records, ten studies met our eligibility criteria. We included studies that reported the impact of floods on water-borne diseases (n = 1), vector-borne diseases (n = 8) and zoonotic diseases (n = 1). Five of the ten studies assessed the connection between flood exposure and malaria. One of these five evaluated the impact of flood exposure on malaria co-infections. The five non-malaria studies focused on cholera, scabies, taeniasis, Rhodesian sleeping sickness, alphaviruses and flaviviruses. Nine of the ten studies reported significant increases in disease susceptibility after flood exposure. Conclusion The majority of included studies of the aftermath of floods pointed to an increased risk of infection with cholera, scabies, taeniasis, Rhodesian sleeping sickness, malaria, alphaviruses and flaviviruses. However, long-term health effects, specifically on mental health, non-communicable diseases and pregnancy, remain understudied. Further research is urgently needed to improve our understanding of the health risks associated with floods, which will inform public policies to prevent and reduce flood-related health risks.

Abstract
In 2019, 30,000 people were forced to leave their homes due to conflict, persecution, and natural disaster each day. Eighty-five percent of refugees live in developing countries, and they often face underfunded and inadequate environmental health services. Many displaced persons live in camps and other temporary settlements long after the displacement event occurs. However, there is little evidence on environmental health conditions in the transitional phase-defined by the United Nations High Commissioner for Refugees as six months to two years after displacement. To address this gap in research, we conducted a systematic scoping review of environmental health conditions, exposures, and outcomes in transitional displacement settings, as well as reported obstacles and recommendations for improvement. Eighty-eight publications met the inclusion criteria. Water supply was the most frequently discussed environmental health topic. Overcrowding was the most common risk factor reported, Vibrio cholerae was the most common pathogen reported, and diarrhea was the most commonly reported health outcome. Obstacles and recommendations were categorized as institutional, political or implementation-based. Identified knowledge gaps included minimal information on setting logistics and on topics such as menstrual hygiene, oral hygiene and fomite contamination. In order to improve environmental health conditions in transitional displacement settings, all levels of government and non-governmental organizations should increase collaboration to improve resource provision. This study is the first to report on environmental health conditions in this important time of transition between the emergency and protracted stages of displacement.

Abebe TA, Tucho GT. Open defecation-free slippage and its associated factors in Ethiopia: a systematic review. Syst Rev 2020; 9:252. [PMID: 33143715 PMCID: PMC7641843 DOI: 10.1186/s13643-020-01511-6] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 10/26/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Recent studies have shown an increase in open defecation and slippage of open defecation-free certified villages in Ethiopia, despite significant progress the country made on sanitation programs. Hence, realizing of existing facts, this study was conducted aiming at a critical review of available literature and to provide consolidated data showing the level of slippage and its associated factors in Ethiopia. METHODS Systematic literature searches were performed from four international databases. The search involved articles published from December 1, 2013, up to June 4, 2019. The Cochran's Q and I2 test statistics were used to check heterogeneity among the studies. To negotiate heterogeneity from qualitative data, we used a mixed-method approach. The researchers also conducted a publication bias assessment and sensitivity analysis. A random effect meta-analysis was employed to determine the pooled estimates of open defecation free slippage rate with a 95% confidence interval (CI). The data analysis was performed using the CMA V.3 software program. RESULT After screening 1382 studies, 12 studies were finally included in this systematic review. The estimated pooled rate of open defecation-free slippage in Ethiopia was 15.9% (95% CI 12.9-19.4%). The main contributing factors for open defecation-free slippage were lack of technical support, financial constraints, low-quality building materials, improper program implementation, and lack of sanitation marketing. CONCLUSION It was estimated that 1 out of 6 Ethiopian households engaged in open defecation after they have certified open defecation-free status, implying the low possibility of achieving sustainable development goals of 2030, which aims to ensure sanitation for all. Therefore, the government of Ethiopia and donors should better give special attention to the following options: (1) awareness for open defecation-free slippage, (2) launch a post-open defecation-free program, and (3) encourage research on pro-poor sustainable sanitation technologies.

Assessment of Knowledge, Attitudes, and Practices on Water, Sanitation, and Hygiene in Some Selected LGAs in Kaduna State, Northwestern Nigeria. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2020; 2020:6532512. [PMID: 32934659 PMCID: PMC7479483 DOI: 10.1155/2020/6532512] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 08/04/2020] [Accepted: 08/16/2020] [Indexed: 01/24/2023]
Abstract
Access to safe water, sanitation, and hygiene (WASH) facilities is a basic necessity for human livelihood, survival, and well-being. Adequate WASH facilities provision is a critical issue to most developing countries around the world including Nigeria. Knowledge, attitudes, and practices regarding WASH are integral to effective and sustainable WASH facilities provision. This study assessed the level of knowledge, behavior, and practices towards water, sanitation, and hygiene in Kaduna state, Nigeria, with a view to ensuring sustainable WASH facilities intervention in the region. Data collection tools included spot check observation and questionnaire involving 854 participants, selected from five local government areas (LGAs): Chikun, Kajuru, Soba, Kachia, and Zango Kataf. From the results, major drinking water sources were surface waters (52.5%) and unprotected hand dug wells (44.8%); only 46.2% treated their water supply and few (16.6%) used chlorination method. Pit latrine toilets were the major (76.5%) excreta disposal means, and open defecation practices were widespread (41.4%). Level of personal and environmental hygiene understanding was fairly good in all the local government areas, and 65.4% claimed to use water and soap for washing hands after defecation. Incidence of water related diseases is generally low in the area. Despite the commendable findings in the study areas, communities are still at risk due to lack of safe water supply and poor practices of home treatment and excreta disposal. Therefore provision of WASH facilities and WASH education is fundamental for ensuring public health in the study area.

Abstract
Background Trachoma is a neglected tropical disease which is the leading infectious cause of blindness in the world. Trachoma is one of the major health problems in Tigray Region, Northern Ethiopia. However, knowledge, attitudes, and practices about trachoma are not yet studied in depth. The objective of the study was to assess knowledge, attitudes, and practices on trachoma and its associated factors among rural communities in two districts of Tigay Region, Northern Ethiopia. Methods A cross-sectional study was conducted in two districts of Tigray Region, Northern Ethiopia, from May 7–24, 2017. Data were collected on paper based, were entered into Epi Info version 3.5.1, and then exported to SPSS version 21 for analysis. Logistic regression analysis was done to identify factors associated with knowledge, attitudes, and practices. Results In this study, a total of 194 respondents were included. The overall level of good knowledge, attitudes, and practices on trachoma was 51%, 49.5%, and 35.6%, respectively. Having ever received health education was significantly associated with good knowledge (adjusted odds ratio (AOR) = 4.10; 95% confidence interval (CI): 1.91–8.79) and attitudes (AOR = 2.10; 95% CI: 1.02–4.25). Moreover, good knowledge was associated with good practices on trachoma prevention and control (AOR = 2.86; 95% CI: 1.46–5.62). Conclusion Our study implies that areas with high burden of trachoma need to improve communities' knowledge, attitudes, and practices towards trachoma prevention and control in order to eliminate trachoma as a public health problem. Therefore, health education focused on SAFE strategy should be provided to increase knowledge and changing attitudes that contribute for good practices towards trachoma prevention and control among communities.

Abstract
Hill tribes are a group of people who live in remote areas in northern Thailand. They typically use untreated water for drinking, that can lead several health problems. The six main hill tribes—Akha, Hmong, Karen, Lahu, Lisu, and Yao—were selected for the study. A validated questionnaire was used for data collection. Water samples were collected from the selected villages and tested for the quality at Mae Fah Luang University, Thailand. Results: the major sources of drinking water were mountain water supplies (74.3%), and commercial bottled water (21.4%). Easy access, sufficiency for the whole year, and food-drug administration sign labeled were the criteria used for selecting sources of drinking water. Colorless and safety were also used as a selection criteria for their drinking water in some tribes. Lisu, Karen, and Hmong treated their drinking water by boiling, while Akha and Lahu stored the water in certain containers to allow particle settling before drinking water without treatment. 42.0% of the water samples had a turbidity values <5 NTU, and total coliform and fecal coliform bacteria were detected in 100.0% of the samples. To prevent water-borne diseases among the hill tribe people, appropriate water treatments such as boiling, filtration, and disinfection are recommended.

Abstract
In developing countries, the waterborne transmission of hepatitis E virus (HEV), caused by HEV genotypes 1 (HEV-1) and 2 (HEV-2), leads to the onset of large recurrent outbreaks. HEV infections are of particular concern among pregnant women, due to very high mortality rates (up to 70%). Unfortunately, good understanding of the factors that trigger the occurrence of HEV epidemics is currently lacking; therefore, anticipating the onset of an outbreak is yet not possible. In order to map the geographical regions at higher risk of HEV epidemics and the conditions most favorable for the transmission of the virus, we compiled a dataset of HEV waterborne outbreaks and used it to obtain models of geographical suitability for HEV across the planet. The main three variables that best predict the geographical distribution of HEV outbreaks at global scale are population density, annual potential evapotranspiration and precipitation seasonality. At a regional scale, the temporal occurrence of HEV outbreaks in the Ganges watershed is negatively correlated with the discharge of the river (r = -0.77). Combined, our findings suggest that ultimately, population density and water balance are main parameters influencing the occurrence of HEV-1 and HEV-2 outbreaks. This study expands the current understanding of the combination of factors shaping the biogeography and seasonality of waterborne viral pathogens such as HEV-1 and HEV-2, and contributes to developing novel concepts for the prediction and control of human waterborne viruses in the near future.

Abstract
BACKGROUND As of the year 2014, about 2.5 billion people globally lacked access to improved sanitation. The situation is even worse in the sub-Saharan African countries including Kenya. The practice of open defecation (OD) peaks beyond 72% of the population in Turkana County, Kenya, despite various interventions to end it. METHODS This article reports on both qualitative and quantitative aspects of a cross-sectional study. A partially mixed sequential dominant (quantitative) status was used to understand various socioeconomic factors associated with OD practice in Lodwar's human settlements, Turkana County. Simple random sampling technique was chosen to select participants for this study with the sample drawn from various administrative units of Lodwar. Standardized questionnaires, focus group discussions, and key informant interviews were used to collect data. RESULTS The quantitative findings revealed that culture was the leading factor as to why people practiced OD with a frequency of 44%. The findings further revealed that poverty was the major influencing factor for latrine ownership among the households (frequency 27%). Pearson χ2 tests revealed that there was a significant association between latrine presence and education level of the household head (χ2 = 107.317; P < .05), latrine sharing (χ2 = 403; P < .05), and occupation of the household head (χ2 = 74.51; P < .05). The quantitative findings showed that culture was by far the most common factor that contributed to the OD practice with a theme intensity of 31.1%. Further analyses identified 5 major cultural aspects that were associated with OD practice. This included sexual immorality, OD as a common habit, nomadic pastoralism, bride's dignity and mixing of feces. Open defecation as a common habit among the respondents was the most cited factor that contributed to its rampant practice (theme intensity 31.3%) followed closely by nomadic pastoralism kind of life among the residents that limit latrine construction (theme intensity 28.1%). CONCLUSIONS In addition to cultural aspects, high poverty levels influence latrine adoption and consequently OD practices. Future sanitation interventions addressing OD should assess and factor in these cultural aspects in such communities to come up with appropriate eradication measures which have otherwise been difficult to solve through poverty eradication and sanitation campaigns that have been in existence.

ENVIRONMENTAL HEALTH INSIGHTS 2019; 13:1178630219887960. [PMID: 31908471 PMCID: PMC6935769 DOI: 10.1177/1178630219887960] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2019] [Accepted: 10/21/2019] [Indexed: 05/22/2023]
Abstract
BACKGROUND Poor latrine conditions, structure, and design may deter latrine use and provoke reversion to open defecation (OD). Statistics show that only 18% of the households in Turkana County, Kenya, have access to a latrine facility with most of these facilities in poor structural designs and poor hygienic conditions, which encourages rampant OD practices. AIM This article reports on quantitative aspects of a larger cross-sectional survey to assess latrine structure, design, and conditions, and the practice of OD in Lodwar. METHODS An observational study was carried out to examine latrine conditions, structure, and design in Lodwar, Kenya. A standardized questionnaire was also used to collect quantitative data. Stratified random sampling technique was employed to select respondents for this study with the sample drawn from 4 administrative units of Lodwar town covering the low-, medium-, and high-income households. Data were managed using Statistical Packages for Social Science (SPSS) software. RESULTS Nineteen percent of the sampled households did not possess a latrine facility at their homesteads with 73% of the latrines constructed using poor materials (mud, mats, polythene bags, and grass). Twenty percent of the respondents were scared of using a latrine with the main reason being loose soils that do not support strong constructions. Eighty-seven percent of the respondents agreed that the presence of feces on the latrine floor encouraged the practice of OD and 321 (80%) respondents stated that the latrine construction materials influenced latrine ownership and its subsequent use. CONCLUSIONS Respondents attributed rampant OD practices to poor latrine structure, design, and conditions. In addition, rampant cases of latrine sharing result in latrine filthiness, which eventually encourages OD practice. Inequality in sanitation, among counties, should be addressed in Kenya. The government should take charge of provision of good-quality communal latrines to the less-privileged societies like Turkana. Community empowerment and introduction of a small fee for cleaning and maintenance of these facilities will also improve their conditions. Ending the practice of OD will lead to increased positive public health and environmental outcomes in the study area.
