Objectives: The study assessed the behavioural contexts of household shared sanitation (SS), the factors that could enhance its cleanliness and sustainable maintenance in the study area., Study Design: The study design was cross-sectional in nature., Methods: A pretested, interviewer-administered questionnaire with 113 questions provided information on knowledge, attitude and SS maintenance practices from 312 respondents selected through a four-stage sampling technique. Data were analysed by descriptive, chi-square and logistic regression statistics with attitude and toilet cleanliness as the dependent variables, while the sociodemographic characteristics, knowledge and practice, including the toilet cleanliness index, were the explanatory variables at P < 0.05., Results: The mean age of respondents was 46.1 ± 16.4 years. The majority were women (62.7%), tenants (64.7%) and had a secondary education (61.3%). In addition, 27.9% and 2.7% of respondents had shops and gender-segregated SS, respectively. Their knowledge and attitudes were good (66.3%) and positive (72.1%), while the majority (60.3%) of the SS was dirty. Almost two-thirds (62.8%) and 37.2% of respondents, respectively, had one and two or more compartments of unimproved pit toilets (31.6%) and water closets (28.6%), while 1.4% practiced open defaecation, despite having SS. More than two-fifths of SS were cleaned daily (45.4%) by women (52%), using water and soap (33.4%). Most households (93.4%) complied with the SS cleaning routines, with non-compliance attributed to lack of interest (29.5%), apathy when others defaulted (27.9%), lack of time (26.2%) and inadequate water (14.8%). There was a significant association between attitudes and education (P = 0.025), wealth (P = 0.011) and toilet-cleaning frequency (P = 0.015). The positive behaviour determinants of SS are factual knowledge (P = 0.039), efforts required to clean (P = 0.019), the ability to remember (P = 0.011) and cleaning commitment (P = 0.040), while freedom of expression among households using SS was a positive predictor of avoiding conflict, among the social dilemma factors., Conclusions: Good knowledge and positive attitudes were reported among users of SS, although with mixed practice and behaviour patterns. Factual knowledge, cleaning commitments and freedom of expressions predict SS cleanliness, which should be reinforced using periodic messages and structured health promotion strategies., (Copyright © 2018 The Royal Society for Public Health.

Background: The environment in the abattoir is of public health concern because of its implications on the quality of meat sold in the markets. The poor sanitary states of abattoirs have been reported in the literature. Very few studies have provided a comprehensive assessment of the sanitary conditions in the abattoir premises. This study sought to assess the compliance of abattoirs in Ibadan, Southwest Nigeria with standards set by Federal Ministry of Environment., Methodology: A descriptive cross-sectional study was conducted in Ibadan using an observational checklist adapted from Policy guidelines on market and abattoir sanitation by the Federal Ministry of Environment. Twelve (12) abattoirs in Ibadan metropolis were assessed. Data obtained were analyzed using descriptive statistics., Results: Concerning general inspection, only one (8.3%) of the abattoirs had adequate access route, potable water supply and functional drainage system. Many had poor solid waste management practices as heaps of refuse littered the surroundings. Internal inspection of the abattoirs revealed that two (16.7%) had adequate space and facilities. Ten (83.3%) had first aid posts even though they were not equipped with materials. Eleven (91.7%) abattoirs had toilet facilities that were either poorly kept or abandoned., Conclusion: This study showed that most of the abattoirs in Ibadan metropolis were operating under unhygienic and sub-standard conditions and lacked basic requirements for a good abattoir as stipulated in the Policy Guidelines on Market and Abattoir Sanitation. There is an urgent need to enforce the minimum standards as stipulated in the policy guidelines.

Inappropriate solid waste management practices in schools in less-developed countries, particularly in major urban communities, constitute one of the major factors leading to declining environmental health conditions. The objective of the authors' descriptive, cross-sectional study was to assess solid waste management problems in selected urban schools in Ibadan, Nigeria. Eight secondary schools with average pupil populations not less than 500 per school were selected randomly. Four hundred questionnaires (50 per school) were administered. In addition, an observational checklist was used to assess the physical environment. Paper and plastics were the most frequently generated wastes. Common methods of solid waste disposal reported were use of dustbins for collection and open burning. Major problems perceived with current refuse disposal methods by the study students were odors, pest infestation, and spillages. Littering and spillages of solid waste were also common features reported. Data suggested inadequate waste management facilities and practices in study schools. The lack of refuse bins may have contributed to waste spillages and the burning practices. Odors may have arisen from both the decay of overstored organic waste rich in moisture and emissions from refuse burning. This scenario poses a community environmental health nuisance and may compromise school environmental quality.

The principal objectives of this study are to (a) investigate the prevalence of elevated blood lead levels (EBLLs) in children of three major cities of Nigeria with different levels of industrial pollution; (b) identify the environmental, social and behavioral risk factors for the EBLLs in the children; and (c) explore the association between malaria (endemic in the study areas) and EBLLs in the pediatric population. The study involved 653 children aged 2-9 years (average, 3.7 years). The mean blood lead level (BLL) for the children was 8.9+/-4.8microg/dL, the median value was 7.8microg/dL, and the range was 1-52microg/dL. About 25% of the children had BLL greater than 10microg/dL. There were important differences in BLLs across the three cities, with the average value in Ibadan (9.9+/-5.2microg/dL) and Nnewi (8.3+/-3.5microg/dL) being higher than that in Port Harcourt (4.7+/-2.2micro/dL). Significant positive associations were found between BLL and a child's town of residence (p<0.001), age of the child (p=0.004), length of time the child played outside (p<0.001), presence of pets in a child's home (p=0.023), but negatively with educational level of caregiver (p<0.001). This study is one of the first to find a significant negative association between BLL and malaria in a pediatric population, and this association remained significant after controlling for confounding diseases and symptoms. The shared environmental and socio-demographic risks factors for lead exposure and Plasmodium (most common malaria parasites) infection in urban areas of Nigeria are discussed along with possible ways that lead exposure may influence the host response to infection with malarial parasites.

The bacteriological quality of drinking water from well, spring, borehole, and tap sources and that stored in containers by urban households in Ibadan was assessed during wet and dry seasons. The MPN technique was used to detect and enumerate the number of coliforms in water samples. Results showed that majority of households relied on wells, which were found to be the most contaminated of all the sources. At the household level, water quality significantly deteriorated after collection and storage as a result of poor handling. Furthermore, there was significant seasonal variation in E. coli count at source (P=0.013) and household (P=0.001). The study concludes that there is a need to improve the microbial quality of drinking water at source and the household level through hygiene education, and provision of simple, acceptable, low-cost treatment methods.
