Objective: To determine Knowledge, Attitude and Practices of Environmental Sanitation in Semi-Urban Communities in Orlu, Imo State, Nigeria. Methods: A cross sectional descriptive design using a multistage random sampling technique to select 426 participants from households and business premises in semi-urban communities in Orlu Local Government Area of Imo State. Data was collected using a pretested, semi structured, interviewer administered questionnaire. Descriptive analyses were done with frequencies and summary statistics to assess the respondents’ knowledge, attitude and practices of environmental sanitation. Results: The results revealed that the mean age of the respondents’ was 37.0 ± 2.2 with a male to female ratio of 1:1.2. Despite high awareness about environmental sanitation (95.0%) reported among the respondents, proportion of them with good knowledge about environmental sanitation (22.9%), attitude (38.6%) and practice (20.8%) towards environmental sanitation was low. The mean quantity of waste generated per week per household or business premise was 14.1 ± 0.94 kg with a majority of the respondents (80.0%), not separating their waste before disposal. The commonest solid waste component generated was organic/perishable materials (74.8%) and the commonest disposal practice reported was open dumping (49.8%). Conclusion: A lot of attention is still required in the development of basic sanitation infrastructure and also, in the promotion of strategies or interventions that influence behavioural change towards environmental sanitation especially in developing countries like Nigeria.展开更多
