Post-intervention Survey on the Knowledge, Attitude, Beliefs and Practices of People in Lagos State, Nigeria about HIV/AIDS.

The purpose of this study was to evaluate the impact of a mass-education campaign on knowledge, attitudes and practice of people leaving in Lagos State, Nigeria. A pre- and post-intervention survey was conducted among 6000 respondents from 116 administrative wards randomly selected from all the 20 Local Government Areas (LGA) in Lagos State (300 respondents per LGA) in January 2002 to document the effect of a series of communication interventions on the prevention of HIV/AIDS implemented between May and December 2001 in the state and to describe the changes that may have occurred in the knowledge base, attitude, beliefs and practices. The result showed that the level of knowledge is relatively high as indicated in both the pre- and post-intervention survey, though there was a gain in knowledge in some areas after the intervention. Respondent's practices as they relate to issues that cause the spread of the disease did not change significantly after the intervention. The study demonstrated that mass campaigns using multiple channels can be effective in HIV/AIDS prevention, with the observed positive change and the sustained level of awareness.
