Background: Diarrhoea diseases are among the leading causes of morbidity and mortality in under-five-children (U-5C) in Nigeria. Inadequate safe water, sanitation, and hygiene account for the disease burden. Cases of diarrhoea still occur in high proportion in the study area despite government-oriented interventions. Objective: To determine the hygiene and sanitation risk factors predisposing U-5C to diarrhoea in Ibadan, Nigeria. Methods: Two hundred and twenty pairs of children, matched on age, were recruited as cases and controls over a period of 5 months in Ibadan. Questionnaire and observation checklist were used to obtain information on hygiene practices from caregivers/mothers and sanitation conditions in the households of 30% of the consenting mothers/caregivers. Data were analysed using descriptive and inferential statistics. Results: Caregivers/mothers' mean ages were 31.3 ±7.5 (cases) and 30.6 ±6.0(controls) years. The risk of diarrhoea was significantly higher among children whose mothers did not wash hands with soap before food preparation (OR=3.0, p<0.05), before feeding their children (OR=3.0, p<0.05) and after leaving the toilet (OR=4.7, p<0.05). Factors significantly associated with diarrhoea were: poor water handling (OR=2.0,CI=1.2-3.5), presence of clogged drainage near the house (OR=2.1,CI=1.2-3.7) and breeding places for flies (OR=2.7,CI=1.6-4.7). The mean risk score among cases and controls from the sanitary inspection of drinking water sources were 5.4 ± 2.2 and 3.2 ± 1.9 (p<0.05) and household storage containers were 2.4 ± 1.8 and 1.2 ± 0.7 (p<0.05) respectively Conclusion: Hygiene and sanitation conditions within households were risk factors for diarrhoea. This study revealed the feasibility of developing and implementing an adequate model to establish intervention priorities in sanitation in Ibadan, Nigeria.

Background: Water pollution from abattoir effluents may create substantial environmental and public health hazards. Available literature is scanty on the quality of groundwater located near abattoirs in tropical developing countries like Nigeria. This study, therefore, accessed the impact of abattoir activities on the quality of groundwater in Omu-Aran Nigeria.Methods: A total of eighteen water samples were taken from five privately own wells and one control well located at varying distances and elevations to the abattoir. The physicochemical characteristics of the water were determined using the standard methods. Data were analyzed using descriptive statistics and ANOVA. Results:The mean values of parameters in the water samples collected from the studied wells ranged from 5.80 ± 0.20 to 7.23 ± 0.55 mg/L, 12.0 ± 1.0 to 26.0 ± 2.0 mg/L, 0.06 ± 0.02 to 0.16 ± 0.02 mg/L and 208.0 ± 24.25 to 254.67 ± 12.22 cfu/mL for dissolved oxygen, biological oxygen demand, lead and total coliforms, respectively. There was a significant difference in the quality of water from the studied and control wells in the parameters except that of total coliform. The quality of the groundwater improved with increasing distance from the abattoir. Conclusions:Findings revealed that abattoirs have the potential to impact the quality of groundwater. Therefore, careful consideration is required when choosing a location for siting new abattoirs. For existing ones, particularly those close to residential areas, effective pollution control measures should be put in place to protect groundwater. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

The study examined the determinants of willingness-to-pay for private solid waste disposal systems by urban households in Ibadan, Nigeria. A multistage random sampling technique was used to select 552 households for the study. Data obtained from survey were analysed using a logit model-based contingent valuation. Evidence from the logit model indicated that seven variables had significant influence on the households' willingness-to-pay. Of these, income and asset owned were positive and significant at P < 0.01 but amount of willingness-to-pay and firm services were negative and significant at P < 0.01. Education and occupation were positive and significant at the P < 0.05 level while age was negative and significant at P < 0.10. The implication is that households have certain socio-economic characteristics, which influence their willingness-to-pay for solid waste disposal. The study recommends government intervention in a variety of forms such as encouraging public-private participation in solid waste disposal, an aggressive environmental clean-up campaign, decentralization of Waste Management Boards and privatization of some aspects of waste management to ameliorate solid waste problems and improve health.

BackgroundSource of potable water has implication on the population health. Availability of Improved Drinking Water Sources (IDWS) is a problem in developing countries, but variation exists across segments of the population. This study therefore examined the relationship between wealth status, sex of household head and source of potable water.MethodsThe 2013 Nigeria Demographic and Health Survey data was used. A representative sample of 40,680 households was selected for the survey, with a minimum target of 943 completed interviews per state covering the entire population residing in non-institutional dwelling units in the country. Households where information on drinking water sources was not reported were excluded, thus reducing the sample to 38021. The dependent and key independent variables were IDWS and Wealth Index respectively. Data were analysed using Chi-square and binary logistic regression (α = .05).ResultsHouseholds that used IDWS were headed by females (66.7 %) than males (58.7 %). Highest proportion of households who used IDWS was found in the rich wealth index group (76.7 %). The likelihood of using IDWS was higher in household headed by females (OR = 1.41; C.I = 1.33–1.49, p <0.001). Households that belong to rich wealth index and middle class were 5.06(C.I = 4.81–5.32, p <0.001) and 2.62(C.I = 2.46–2.78, p <0.001) respectively times more likely to IDWS than the poor. This pattern was sustained when other confounding variables were introduced into the regression equation as control.ConclusionsHouseholds headed by women used improved drinking water sources than those headed by men. However, wealth index has strong influence on the strength of relationship between sex of household head and improved drinking water sources.
