Exploring the determinants of under-five mortality and morbidity from infectious diseases in Cambodia—a traditional and machine learning approach

Cambodia has made progress in reducing the under-five mortality rate and burden of infectious diseases among children over the last decades. However the determinants of child mortality and morbidity in Cambodia is not well understood, and no recent analysis has been conducted to investigate possible determinants. We applied a multivariable logistical regression model and a conditional random forest to explore possible determinants of under-five mortality and under-five child morbidity from infectious diseases using the most recent Demographic Health Survey in 2021–2022. Our findings show that the majority (58%) of under-five deaths occurred during the neonatal period. Contraceptive use of the mother led to lower odds of under-five mortality (0.51 [95% CI 0.32–0.80], p-value 0.003), while being born fourth or later was associated with increased odds (3.25 [95% CI 1.09–9.66], p-value 0.034). Improved household water source and higher household wealth quintile was associated with lower odds of infectious disease while living in the Great Lake or Coastal region led to increased odds respectively. The odds ratios were consistent with the results from the conditional random forest. The study showcases how closely related child mortality and morbidity due to infectious disease are to broader social development in Cambodia and the importance of accelerating progress in many sectors to end preventable child mortality and morbidity.

High lead contamination in Mother's breastmilk in Bihar (India): Health risk assessment of the feeding children

Lead poisoning in the recent times has caused serious health threats in the exposed human population. It is estimated that about 815 million people are exposed to lead poisoning worldwide and in India total 275 million children are exposed to blood lead contamination. The present study was carried outed in 6 districts of Bihar to know the extent of lead exposure in the children through their mother's breastmilk. The biological samples such as breastmilk, mother's urine, child's urine, and mother's blood samples were collected for quantitative lead estimation. Moreover, the selected household water sources (handpump) and the food consumed by the individuals-wheat, rice and potato samples were also collected for lead quantification. The study reveals that the breastmilk had high lead content in 92% of the samples (highest value 1309 μg/L), in blood presence of lead was observed in 87% studied samples (highest value 677.2 μg/L). In mother's urine the highest lead value was 4168 μg/L (62%) and in child's urine the highest value was 875.4 μg/L (62%) respectively of the studied samples. Moreover, in the studied food samples, wheat had lead content in 45% the studied samples (highest value 7910 μg/kg). In rice in 40% of the studied samples (highest value 6972 μg/kg) and in potato 90% of the studied samples (highest value = 13786 μg/kg) were found with elevated lead content respectively. The hazard quotient (HQ) and the cancer risk (CR) for lead contamination was very much higher in mothers followed by their children. The entire study indicated that lead exposure through food (wheat, rice and potato) has reached the mother's breastmilk and from their it has reached their child's body. This could cause serious hazards in the exposed children causing serious neurological damages, low IQ, low memory, and low mental growth in them. Therefore, a strategic action is required to control the present problem.

Use of engineering economic equivalence tenets to prioritize water source(s) for use by households, ‘The Case of Mbeya City – Tanzania’

ABSTRACT In Tanzania, inadequate water access impacts 26% of urban and 38% of rural populations, heavily reliant on piped water systems prone to rationing. Low-income earners suffer from high water bills and poor water quality. Alternative sources like gravity-fed systems, rain harvesting, and drilled wells are overlooked, lacking evaluation using engineering economic equivalence (EEE) principles for prioritization. This study fills this gap by examining the literature and using Mbeya City data from users of tapped water, rain harvesting, and drilled wells to prioritize household water sources. EEE computations determine the present worth, valuing tapped water systems, rain harvesting, and drilled wells at Tshs 11,009,424/-, 10,283,000/-, and 12,099,940/-, respectively. Although rain harvesting seems favorable, it is unsuitable for drinking, and tapped water systems involve fluctuating daily costs. Consequently, the ‘drilled water system’ is the preferred option for sustainable household water access.

Associated factors of dietary diversity among schoolchildren in Plateau Central region of Burkina Faso: a cross-sectional study

ContextSchool-age is a dynamic period of growth and development, leading to good health and a productive adult life. Adequate dietary intake provides essential nutrients for growth, health and cognition. However, the practices of adequate nutrition is still not a matter of course for schoolchildren in many countries. The aim of this study was to identify associated factors of dietary diversity among students in public primary school in the Central Plateau Region.MethodMulti-stage sampling was used to select schoolchildren. A semi-structured questionnaire was used to collect information’s of food consumption at home and at school using a 24-h dietary recall method. Binary logistic regression was used to identify variables associated with students' dietary diversity scores (DDS) with statistical significance at p < 0.05, after performing Chi-square test of independence to identify candidates variables at p < 0.25.ResultsThe study involved 560 pupils aged 6 to 14 older, including 52.9% girls and 47.9% boys. Dietary diversity was divided into three classes: low (DDS ≤ 4), medium (DDS = 5) and high (DDS ≥ 6). Thus, 13.4% of students have a low DDS and average in 48.9%, versus 37.7% high. Students in Ganzourgou were twice as likely to have a low DDS (AOR = 2.01, 95% CI:1.00–4.04) compared to those in Oubritenga. Household drinking water source, pupil status and father's occupation were significantly associated with pupils' dietary intake.ConclusionPrimary schoolchildren don’t have good dietary practices in the Plateau Central Region. Promoting dietary diversification in households and balanced meals in school canteens would be necessary to improve the DDS of schoolchildren.Trial registrationClinical Trial Number: 2022_33_/MS/MESRSI/CERS of 02/14/2022.

Climate change, seasonality and household water security in rural Gambia: A qualitative exploration of the complex relationship between weather and water

Climate change could pose a threat to water security for many communities, particularly in settings where rainfall patterns are becoming more varied and there is higher frequency of extreme events, such as heavy rainfall and droughts. Understanding how rainfall affects water security—including water access, water quality and water use behaviours—can inform investment in more climate-resilient infrastructure and safeguard against future health risks. This study aims to explore how households in rural Gambia experienced water security in relation to seasonal rainfall patterns and extreme weather events. Data collection focused on two communities (Kiang West and Basse) with differing access to water infrastructure, within which some villages had greater access to groundwater sources, such as solar-powered boreholes, and others primarily used uncovered wells. 46 participants were interviewed in Spring 2022 using multiple qualitative methods, including in-depth interviews and transect walks. We found that people’s experience of water security and rainfall (including seasonal rainfall, drought and heavy rainfall) was complex and varied according to the primary household water source. Both dry and rainy season posed challenges to household water security in terms of quality and quantity. Households with access to more resilient infrastructure, such as solar-powered boreholes, discussed a shift in the relationship between weather and water security, where they were less vulnerable to water shortages during dry conditions compared to those using wells. However, these sources did not fully resolve water security issues, as they experienced water shortages during cloudy conditions. Extreme weather events, such as heavy rainfall, heightened perceived water issues, as these events sometimes damaged water infrastructure and contaminated water sources. Seasonal workloads, that were higher in the rainy season, also jeopardised water security, as this limited time for water collection. Increased investment in infrastructure, maintenance, water-treatment and behavioural change is required to mitigate the risks.

Prevalence and determinants of minimum dietary diversity for women of reproductive age in Uganda

BackgroundGlobally, over a billion women of reproductive age (WRA) suffer from some kind of undernutrition micronutrient deficiencies, and/or anemia as a result of inadequate dietary diversity. This leads to poor maternal and child health outcomes, however, there is limited research on population level research on minimum dietary diversity for women (MDD-W). This study assessed the prevalence and predictors of MDD-W among WRA in Uganda.MethodsThis study was a secondary analysis of data from the lot quality assurance sampling (LQAS) survey conducted across 55 Ugandan districts between May and September 2022. Women of various ages were interviewed across 5 study subgroups that this study used to construct its study population (WRA). Descriptive analyses, tests for outcome differences, and multilevel mixed-effects logistic regression were conducted at a 5% statistical significance level using STATA version 17. The results were reported using Adjusted Odds Ratios (aOR) as the measure of the outcome.ResultsThe study analyzed responses from 29,802 WRA with a mean age of 27.8 (± 6.8) years. Only 8.8% (95% CI 8.5–9.3) achieved the MDD-W, the least proportion was observed in the South-Central region (3.13%). In the adjusted analysis, WRA who were older than 25 years (aOR 1.1, 95% CI 1.1–1.3, p < 0.001), had secondary education (aOR = 1.4, 95% CI 1.1–1.7, p = 0.003) or above (aOR = 1.7, 95% CI 1.3–2.2, p < 0.001), and used modern contraceptives (aOR = 1.1, 95% CI 1.0-1.3, p = 0.01) were more likely to achieve the MDD-W. Conversely, WRA who travelled longer distances to the nearest household water source (aOR = 0.8, 95% CI 0.7–0.9, p = 0.002) and those residing in larger households (aOR = 0.9, 95% CI 0.8-1.0, p = 0.019) were less likely to achieve the MDD-W.ConclusionA low proportion of WRA met the MDD-W. Age, education level, household sizes and use of modern contraception were predictors of MDD-W among WRA in Uganda. MDD-W-related program efforts in Uganda should strengthen multisectoral collaboration with prioritization of younger women, education, household sizes and access to safe water sources.

Suboptimal Bacteriological Quality of Household Water in Municipal Ibadan, Nigeria.

Access to potable water is difficult for many African residents. This study evaluated the bacteriological quality of household water collected in the dry and wet seasons across five municipal local government areas (LGAs) in Ibadan, a large city in southwest Nigeria. A total of 447 water samples (dry season, n = 250; wet season, n = 197) were aseptically collected from a random sample of mapped households within Ibadan's five municipal LGAs. The pH values and total aerobic and coliform bacterial counts were measured, and samples were screened for Escherichia coli, Salmonella, Shigella, and Yersinia by standard phenotypic techniques and multiplex polymerase chain reaction. The most common source of water was well (53.2%), followed by borehole (34%). None of the households used municipal tap water. Cumulatively, aerobic (P = 0.0002) and coliform (P = 0.0001) counts as well as pH values (P = 0.0002) changed significantly between seasons, with increasing and decreasing counts depending on the LGA. Nonpotable water samples were found to be very common during the dry (86.8%) and wet (74.1%) seasons. Escherichia coli spp., as indicators of recent fecal contamination, were isolated from 115 (25.7%) of the household water sources. Thirty three Salmonella, four enteroaggregative E. coli, and four enterotoxigenic E. coli isolates but no Shigella or Yersinia isolates were identified. This study revealed the absence of treated tap water and the poor quality of alternative sources with detectable pathogens in municipal Ibadan. Addressing the city-wide lack of access to potable water is an essential priority for preventing a high prevalence of feco-orally transmitted infections.

Household environment associated with anaemia among children aged 6–59 months in Ethiopia: a multilevel analysis of Ethiopia demographic and health survey (2005–2016)

BackgroundAnaemia continues to be a major public health challenge globally, including in Ethiopia. Previous studies have suggested that improved household environmental conditions may reduce anaemia prevalence; however, population-level evidence of this link is lacking in low-income countries. Therefore, this study aimed to examine the association between environmental factors and childhood anaemia in Ethiopia.MethodsIn this study, we conducted an analysis of the data from the Ethiopian Demographic and Health Survey (EDHS), a nationally representative population-based survey conducted in Ethiopia between 2005 and 2016. The study included a total of 21,918 children aged 6–59 months. Children were considered anemic if their hemoglobin (Hb) concentration was less than 11.0 g/dl. To examine the association between environmental factors and anemia, we used multilevel mixed-effect models. These models allowed us to control for various confounding factors including: child, maternal, household and community-level variables. The study findings have been reported as adjusted odds ratios (AORs) along with 95% confidence intervals (CIs) at a significance level of p < 0.05.ResultsThe study found the overall prevalence of childhood anaemia to be 49.3% (95%CI: 48.7–49.9) between 2005 and 2016 in Ethiopia. The prevalence was 47.6% (95%CI: 46.1–49.1) in 2005, 42.8% (95%CI: 41.8–43.8) in 2011, and increased to 57.4% (95%CI: 56.3–58.4) in 2016. The pooled data showed that children from households practising open defecation were more likely to be anaemic (AOR: 1.19, 95% CI: 1.05–1.36). In our survey specify analysis, the odds of anaemia were higher among children from households practising open defecation (AOR: 1.33, 95% CI: 1.12–1.58) in the EDHS-2011 and EDHS-2016 (AOR: 1.49, 95% CI: 1.13–1.90). In contrast, neither household water sources nor the time to obtain water was associated with anaemia after controlling for potential confounders. The other variables significantly associated with childhood anaemia include: the child’s age (6–35 months), not fully vaccinated (AOR: 1.14, 95%CI: 1.05–1.24), children not dewormed in the last 6 months (AOR: 1.11, 95%CI: 1.01–1.24), children born to mothers not working (AOR: 1.10, 95%CI: 1.02–1.19), children from poor households (AOR: 1.18: 95%CI: 1.06–1.31), and rural residence (AOR: 1.23, 95%CI: 1.06–1.42).ConclusionIn Ethiopia, about fifty percent of children suffer from childhood anemia, making it a serious public health issue. Open defecation is a major contributing factor to this scourge. To address this issue effectively, it is recommended to strengthen initiatives aimed at eliminating open defecation that involve various approaches, including sanitation infrastructure development, behavior change campaigns, and policy interventions. In addition, to reduce the burden of anemia in children, a multi-faceted approach is necessary, involving both prevention and treatment strategies.

Armed conflict and household water sources

AbstractAccess to safe drinking water is among the most important determinants of public health outcomes. We pair household-level data from Iraq together with data on armed conflict and adopt a generalized difference-in-differences approach to study the relationship between household drinking water sources and armed conflict intensity. We find that households located in conflict-affected areas are more likely to use piped water accessed at their homes or bottled water as their primary source of drinking water, but are less likely to use public water sources or tanked water delivered on trucks and carts. We explore the temporal dynamics of these adjustments as well as heterogeneity by household characteristics. We further present direct evidence that conflict-exposed households are less likely to travel to obtain water.

Impact and interventions of waterborne and foodborne illnesses caused by bacterial pathogens in Nigeria: A review

Waterborne and foodborne illnesses caused by bacterial pathogens are major public health concerns, especially in developing countries like Nigeria—waterborne pathogens such as Escherichia coli, Salmonella spp. and Klebsiella spp. Contribute to the spread of health challenges, primarily due to poor sanitation, contaminated drinking water, and inadequate hygiene. Similarly, foodborne pathogens, including Escherichia coli, Listeria monocytogenes and Salmonella spp., are major causes of human illness, with animal-based foods often acting as transmission vectors. This review examines the current state of diagnosis, highlighting that most household water sources in Nigeria are vulnerable to contamination, with significant microbial loads exceeding WHO standards. It raises the need for effective interventions such as improved hygiene practices, water supply, sanitation and food safety management systems. Furthermore, this review discusses the impact of these pathogens on public health, noting that waterborne and foodborne diseases result in substantial mortality and economic burdens. Also, implementing good hygienic practices, Hazard Analysis Critical Control Point (HACCP) systems, and public health education are essential strategies for reducing the incidence of these diseases. This review concludes by calling for a collaborative effort among governments, policymakers, stakeholders, and researchers to develop and implement multifaceted interventions to combat these pervasive health threats.

Physico-Chemical and Bacteriological Quality of Household Drinking Water from Source to Point of Use in Akewu Community in Ibadan, Oyo State, Southwest, Nigeria

Poor household water storage is one of the major factors contributing to contamination of drinking water in Nigeria. Studies have shown that sizes of containers opening can affect water quality, but little has been documented on comparative effect of storage containers with different opening sizes in improving drinking water quality in Ibadan. This study was designed to assess the effect of different storage containers on household drinking water quality in selected communities in Ibadan. A quasi-experimental design was adopted. Four communities in Ibadan North Local Government namely; Akewu using protected springs as household drinking water sources were purposively selected. Forty-four households (11 from each community) were selected and randomly assigned to four treatment groups; those with Covered Buckets with Taps (CBT), Covered Buckets without Tap (CB), Covered Kegs with Taps (CKT) and Covered Kegs without Tap (CK). Prior to introducing the treatment containers, water samples were collected from their Regular Storage Containers (RSC) and springs for physicochemical and bacteriological analysis using standard methods. Participants were thereafter encouraged to store drinking water in the treatment containers provided for them. Water samples were later collected from CBT, CB, CKT and CK containers twice daily for 3 alternate days over two weeks for bacteriological analysis. In addition, oldest female of selected households were interviewed using a pre-tested semi-structured questionnaire to elicit information on their socio-demographic characteristics, storage container cleaning and handwashing practices. Results of physicochemical and bacteriological findings were compared with Standard Organisation of Nigeria (SON) guidelines. Data were analysed using descriptive statistics, t- test and ANOVA at p=0.05. At baseline, mean pH values of water samples from the springs and RSC were 6.4±0.6 and 7.1±0.7 respectively compared with 6.5-8.5 limits recommended by SON. Mean chloride concentration of springs (14.3±7.4mg/l) and RSC (19.3±10.0 mg/l) samples were below 250mg/l limit recommended by SON. Mean Total Coliform Count (TCC) of the springs in the four communities was 18.0±4.0 and mean TCC of RSC was 12.7±4.9 which exceeded the SON standard of 10MPN/100ml. Five percent of water samples from RSC had mean E.coli count of 100/100ml compared with SON guidelines of 0/100ml. The mean TCC after introducing CB, CBT, CK and CKT in all the communities were 10.0±4.0, 8.5±4.2, 6.9±2.8 and 7.3±3.7 respectively (p&lt;0.05). No E.coli was found in the samples collected from the treatment storage containers. The percentage difference of coliform count in water from springs and RSC was 29.4% while percentage difference from RSC and CB, CBT, CK and CKT were 21.5%, 33.2%, 45.5% and 42.5% respectively. Mean age of the 44 respondents interviewed was 37.9±10.7years. Seventy-three percent washed their hands with only water after defecation and 95.0% stored water for cooking and drinking in the same container. Sixty-eight percent cleaned their containers weekly while 32.0% cleaned twice weekly.

Evaluation of Ground Water Quality in Yeliyur Grama Panchayath Villages, Kunigal Taluk

Life on Earth is dependent on water, which is an essential component of the atmosphere. The source of household water for millions of homes in both rural and urban areas is the tube well. Groundwater is the most alternative is facing threats. Tube well and open well samples were collected at different sites of Yeliyur grama panchayath Villages, Kunigal Taluk. The Physico- Chemical properties of all the collected 20 groundwater samples were analyzed. The quality of groundwater in and around Yeliyur grama panchayath Villages, Kunigal Taluk has been studied various parameter such as pH, Total Dissolved Solid (TDS), total hardness, total alkalinity, turbidity, Na+, K+, Cl-, F-, Ca2+, Mg2+, SO42-, NO32-, DO, Chromium and Pb. The final experimental results were compared with the WHO variable standards (2021).

E. coli contamination of drinking water sources in rural and urban settings: an analysis of 38 nationally representative household surveys (2014-2021).

The world is not on track to achieve universal access to safely managed water by 2030, and access is substantially lower in rural areas. This Sustainable Development Goal target and many other global indicators rely on the classification of improved water sources for monitoring access. We aimed to investigate contamination in drinking water sources, comparing improved and unimproved sources in urban and rural settings. We used data from Multiple Indicator Cluster Surveys, which tested samples from the household water source and a glass of water for Escherichia coli contamination across 38 countries. Contamination was widespread and alarmingly high in almost all countries, settings, and water sources, with substantial inequalities between and within countries. Water contamination was found in 51.7% of households at the source and 70.8% in the glass of water. Some improved sources (e.g., protected wells and rainwater) were as likely to be contaminated as unimproved sources. Some sources, like piped water, were considerably more likely to be contaminated in rural than urban areas, while no difference was observed for others. Monitoring water contamination along with further investigation in water collection, storage, and source classification is essential and must be expanded to achieve universal access to safely managed water.

Potential risk of stunting in children under five years living by the riverside: A systematic review

Introduction: Stunting, or linear growth failure, is defined by a height-for-age z-score of below -2SD according to WHO growth standard. Stunting can have short-, medium-, and long-term consequences. Rivers have an important role in human life. In several riverside areas, households still depend on the river for their livelihoods and health. This study aimed to explore the prevalence of stunting in children living by the riverside and its related factors. Methods: Epidemiological studies published from PUBMED, MEDLINE via EBSCOHost, Science Direct, ProQuest, and Research Gate databases were systematically searched. The publication period was not restricted. Only open-access and English articles were examined. Results: A total of 20 from 1200 studies were reviewed. The prevalence of stunting ranged from 20% to 48.3%. The other outcomes besides stunting were wasting and underweight status. There were 83 risk factors studied, and the most studied variables were age, gender, diarrhoea, water source, parent’s education, immunisation, and inappropriate complementary feeding practices (6 to 13 studies). Household water sources from rivers and economic status were consistently correlated with stunting. Majority of the risk factors studied were related to nutrition. From the environmental aspect, the most studied risk factors were water sources and sanitation. Conclusion: Children living by the riverside face a significant risk of stunting attributed to the consistent correlation between household water sources from rivers and economic status, affecting various aspects of daily life beyond drinking water. Future research is needed to examine the impact of environmental factors and the behaviours of riverside communities.

Microbial community function and bacterial pathogen composition in pit latrines in peri-urban Malawi

Despite the widespread global reliance on pit latrines as improved sanitation systems, the decomposition of waste within pit latrines is poorly understood. One area needing elucidation is the characterization and function of microbial communities within pit latrines. To address this gap, we characterized the microbial communities of 55 lined pit latrines at three sampling layers from two communities in peri-urban Malawi. The microbial communities of the fecal sludge samples were analyzed for beta diversity, pathogen presence, and functional profiling. Household surveys were conducted and used to compare microbial community patterns to household characteristics and pit latrine use patterns. Compared to activated sludge, anaerobic digestion in municipal wastewater systems, and human gut microbiomes, pit latrines were found to contain unique microbial communities. While the microbial community composition as a whole did not vary by sampling depth, pathogen composition varied by sampling depth, location, and household water source. The inferred microbial function also varied by depth (e.g., increase in methanogens and decrease in aerobes with depth). The richness of lined pit latrines determined from surface samples from eight latrines was found to be representative for a given area. Samples from middle and lower depths collected using a Gulper pump did not provide more information on richness, a result that informs future sampling designs. These findings are important for improving waste-based epidemiology (WBE) approaches to understand community health and waste degradation characterization of lined pit latrines.

Source of household water as main risk factor of soil-transmitted helminth infections among elementary school pupils in Wamena District, Jayawijaya Regency, Papua

BackgroundSoil-transmitted helminth (STH) infections are caused by three types of worms: Ascaris lumbricoides, Trichuris trichiura, and hookworms. Soil-transmitted helminth infections have significant health and socioeconomic implications for communities in developing countries, particularly in Indonesia. This study aims to determine the prevalence and risk factors of STH infections among elementary school pupils in Wamena District. MethodsThe study design used was a cross-sectional design involving 317 elementary school pupils. The children were interviewed using a structured questionnaire that included demographic information, hygiene, and environmental sanitation data of the respondents. Stool samples were collected from all consenting participants in sterile plastic containers and were analyzed within 24 hours of collection, using the Kato-Katz method. The data were analyzed using bivariate statistical analysis (Chi-square) and multivariate analysis (logistic regression). ResultsThe prevalence of helminthiasis among elementary school pupils was 19.9% (63/317). STH prevalence of mild category was 17.4% (55/317). The risk factors for STH infections among school children were the habit of not washing hands with soap after defecation, with an odds ratio of 5.04 [95% CI (2.22-11.48)], and the source of water for household use, with an odds ratio of 7.22 [95% CI (3.66-14.22)]. ConclusionThe prevalence of helminthiasis was found to be 19.9% (63/317), with an STH prevalence of mild category. Risk factors for STH infections included the habit of not washing hands with soap after defecation and the source of water for household use.

Water Quality Assessment of Sahastradhara Stream, Dehradun, Uttarakhand, India

Sahastradhara stream is a main attraction of tourist as well as source of household and potable water for the region and the surrounding villages. The stream is being polluted attributable to a variety of human-made activities and water quality is being deteriorated. During these studies, water samples were collected from the three different The physical-chemical characteristics of the water, including temperature, pH, transparency, turbidity, DO, BOD, CO2, alkalinity, and chloride, were analysed at Site-I (the reference Site), Site-II (the more popular tourist destination, severely contaminated Site), and Site-III (moderately polluted). The Physico-chemical parameters were recorded highest at Site-II (DO 7.5mg/l), Turbidity (58.1-80.16 NTU), Alkalinity (245.4-308.2mg L-1), pH (6.1-7.2), temperature (25.60C-27.60C), BOD (1.5 mg/l-2.6mg/l), CO2 (1.5-1.83) followed by S-3 (temperature 26.2-27.20C, pH 7.1-7.2, tur. 79.2-81.1cm, DO 8.1-8.2mg/l, CO2 1.62-1.81, Alkalinity 255.6-262.2 mg/l, BOD, 2.3-2.4 mg/l, Chloride 32.1-32.5 mg/l) and S-I (temperature 25.6-26.30C, pH 7.0-7.1, turbidity 60.2-68.2cm, DO 8.5, CO2, 1.53-1.62 mg/l, Alkalinity, 250.2-256.6 mg/l, BOD,1.5-1.6 mg/l, chloride, 30.0-30.2 mg/l). The study has shown that water at Site-I of Sahastradhara stream is suitable for human use and other purposes, whereas Due to a major change in the water quality of the Sahastradhara stream brought on by various touristic and anthropogenic activities, the water at Sites II and III is unfit for all uses. At the 5% level of significance, every parameter changed considerably over the study period.

Domestic water quality and the discriminatory influence of socio-economic stratification on accessibility to safe water in a part of Osun State, Nigeria

The status of the water supplied to households in an urban local government area in southwest Nigeria was examined. Specific objectives were to characterize household water sources, assess the per capita usage of potable water sources and examine quality of the household water in the area. The purposively selected study area, Olorunda local government area in Osun State, Nigeria (being an urban local government area) was stratified into ‘urban core’ (central business district, CBD or high population density area), ‘transition’ (medium population density area but with less social infrastructure) and ‘sub-urban’ (typically government reserved area and low population density area) based on household density and associative socio-economic status. The methods were a mix of questionnaire administration to heads of 120 households (40 per stratum) and collection of the drinking water samples from the supply sources at four randomly selected households in each stratum. The water samples were analysed for the concentrations of nitrite (NO2-), nitrate (NO3-), fluoride (F-), lead (Pb) and arsenic (As) as well as E-coli bacteria contents based on their importance in determining water quality in urban areas. The results showed that domestic water sources are mainly hand dug well (55.8%), borehole (37.5%) and pipe borne (6.7%). Residents averagely consumed at most 4L of water per day. Furthermore, the investigated chemical parameters varied as NO2 (0.37-0.94 mg/l), NO3 (0.29-0.70 mg/l), and F- (0.003-0.97 mg/l). As and Pb occurred in trace quantities, and there were no pollution threats to consumers. The amount of E coli and total coliform contents were however outside the safe limits for residents, suggesting contamination of household water by the bacteria sources. The study concluded communities with low socio-economic status which do not have access to state-provided tap water source are more likely to consume polluted water than those with high socio-economic status or that are supplied with state-provided tap water. The study advocates improve urban water management for the urban fringe dwellers.

Exploring associations between household environmental factors and handwashing with essential agents in sub-Saharan Africa.

3 billion people lack proper home hand hygiene facilities globally. Of these, 1.4 billion (18%) lack soap or water, while 1.6 billion (22%) have neither. This analysis explores the link between living conditions and the use of essential agents in sub-Saharan Africa. This secondary data analysis examines potential associations between the domiciliary environment and the use of essential agents in sub-Saharan Africa. Eighteen demographic and health surveys were used to analyze the association between household environmental factors and handwashing with essential agents. STATA version 16 was used to analyze data from 203,311 households across weighted samples. Using a multivariable multilevel mixed effect logistic regression analysis, it was possible to determine how each independent factor affected the outcome while taking the data clustering into account. The adjusted odds ratio and its associated 95% confidence interval were used to assess the independent factors' statistical significance. Only one in three households 34.84%, practiced handwashing with essential agents, with the highest prevalence in Angola (70.2%) and the lowest in Malawi (6.5%). Educational status [aOR = 1.77; 95%(CI = 1.68-1.86)], female headship[aOR = 1.09; 95%(CI = 1.06-1.2)], household wealth[aOR = 4.08; 95%(CI = 3.84-4.33)], not sharing toilets with other homes[aOR = 1.13; 95%(CI = 1.10-1.17)], having a fixed place for hand washing[aOR = 1.49; 95%(CI = 1.45-1.54)], not having regular access to water [aOR = 0.09; 95%(CI = 0.095-0.10)]and being a rural resident [aOR = 0.85; 95%(CI = 0.82-0.88)] were associated with handwashing. sub-Saharan nations are failing to demonstrate advancements in handwashing practices. There are still a lot of homes without access to basic infrastructure for handwashing and household water sources. For essential agent adoption programs to be successful in an environment with limited resources, Water, Sanitation, and Hygiene measures must be implemented. Furthermore, it is critical to include contextual factors from the current study as well as socio-cultural and psychological characteristics that dissuade people from using essential agents in intervention strategies.

Association between living environmental quality and risk of arthritis in middle-aged and older adults: a national study in China.

The association between combined environmental factors and the risk of arthritis is still scarcely studied. The present study performed cross-sectional and cohort studies to explore the association between risk score of living environment quality and the risk of arthritis in middle-aged and older adults in China. The study was based on China Health and Retirement Longitudinal Study (CHARLS), and it recruited 17,218 participants in the cross-sectional study and 11,242 participants in the seven-year follow-up study. The living environment quality was measured by household fuel types, household water sources, room temperature, residence types, and ambient concentration of PM2.5. Logistic regression and Cox proportional hazard regression models were utilized to examine the association between the living environment quality and the risk of arthritis. Competing risk models and stratified analyses were applied to further verify our results. Compared with individuals in the suitable environment group, people who lived in moderate (OR:1.28, 95%CI: 1.14-1.43) and unfavorable environments (OR:1.49, 95%CI:1.31-1.70) showed higher risks of arthritis when considering the multiple living environmental factors (P for trend <0.001) in the cross-sectional analysis. In the follow-up study, similar results (P for trend = 0.021), moderate environment group (HR:1.26, 95%CI:1.01-1.56) and unfavorable environment group (HR: 1.36, 95%CI: 1.07-1.74), were founded. Inferior living environment might promote the development of arthritis. It is necessary for the public, especially old people, to improve the living environment, which may be the key to the primary prevention of arthritis.
